A disease caused by oxygen deprivation. Hypoxia - what is this disease? What are the dangers of posthypoxic changes

Hypoxia does not fall under the category of "specific diseases". It can be due to the most incredible reasons and be the main element of all kinds of ailments. Therefore, many find it difficult to understand this unnatural process, since henceforth they encountered only specific diseases that have vivid signs.

This is a general painful process, the interpretation of which should begin with disorders that occur at the intercellular level.

Changes fall into two categories:

1. Adaptive reactions;
2. decompensation.

Initially, the human body tries to somehow respond to a developing disease, activating its adaptive reflexes. It is they who, for a short time, help organs and tissues work stably in cases of possible starvation.

When hypoxia is prolonged, adaptation reactions are no longer enough to maintain tone. The pledged resources are gradually depleted, and a period of decompensation sets in. There are irreparable changes in the body. They lead to negative consequences, including death.

Four degrees

Doctors draw the attention of the population to four degrees of hypoxia, depending primarily on its severity and severity of the course:

Light

revealed during various kinds of physical activity.

Moderate

can manifest itself in a state of absolute rest.

heavy

characterized by a pronounced hypoxic syndrome and has a tendency to go into a coma.

critical

extreme, resulting in hypoxia leading to coma or death.

Reasons for development

The following circumstances should be attributed to the root causes:

• Altitude, for example, mountain sickness or illness of pilots;
• cramped rooms, crowds of people;
• stay in an underground mine;
• improper ventilation system;
• work at depth, under water;
• smoke in the air in the place of residence;
• malfunctions in the functioning of anesthesia and respiratory equipment.

The basis of endogenous hypoxia is considered:

• Respiratory diseases: pneumonia, bronchitis and others;
• the ingress of third-party things into the bronchi in case of swallowing small parts by children;
• asphyxia;
• heart defects: open foramen ovale, ductus arteriosus;
• dysfunction of the respiratory center of the central nervous system in case of injuries, tumors;
• fracture of the chest, damage to the diaphragm;
• heart rhythm failures;
• thrombosis;
• anemia;
• poisoning with synthetic substances;
• blood loss;
• diabetes mellitus, obesity;
• coma;
• chronic diseases of the kidneys, blood;
• problems with the thyroid gland;
• starvation, alcoholism, drug use.

Main types

Doctors divide hypoxia into classes. This division is actively used in science as the most extensive and reasoned.

Given the variant of appearance, pathology happens:

• exogenous, which directly depends on environmental factors.
• Endogenous due to external ailments.

For endogenous, the following subspecies are characteristic:

• respiratory;
• circulatory;
• hemic;
• tissue;
• substrate;
• reloading;
• mixed.

According to the rate of occurrence of hypoxia, they are divided into:

1. Lightning - lasts about 3 minutes.
2. Acute - no longer than 2 hours;
3. Subacute - up to 5 hours;
4. Chronic - can last for weeks or years.

Depending on the limits of oxygen starvation, hypoxia can be general and local.

Let's take a closer look at each of the existing types.

exogenous

It is directly related to the oxygen that a person inhales every second. Due to its small volume, during inhalation, the lungs are little enriched with oxygen. After that, the blood, poorly saturated with oxygen, spreads throughout the body to organs and tissues, and those, in turn, are subjected to hypoxia. It is also possible the appearance of cyanosis, dizziness, loss of consciousness.

Respiratory

Appears due to some disease of the respiratory organs. In the region of the pulmonary alveoli, there are obstacles for the instant connection of hemoglobin with the most important oxygen. As a result, a serious insufficiency or swelling of the brain develops.

Circulatory

Associated with circulatory disorders. When such changes concern all blood vessels, then hypoxia acquires the appropriate name "systemic". And when, for some reason, blood circulation is disturbed only in the region of one organ, then this is local.

With this type of blood, there is the necessary proportion of oxygen, but interruptions in circulation do not allow it to reach specific organs in time.

Hemic

It is characterized by a rapid decrease in hemoglobin. It includes two subspecies: anemic and caused by deterioration in the quality of hemoglobin. Anemic speaks of anemia and a decrease in the amount of hemoglobin. And the second type involves poisoning with poisons that form a form of hemoglobin that is not able to carry oxygen.

tissue

In this type, the cells stop absorbing oxygen. This is done in the following cases:

• Suppression of enzyme activity;
• lack of enzymes due to lack of vitamins;
• poisoning by toxic substances of microbes;
• with radiation, serious infectious diseases.

Substrate

There is a normal delivery of oxygen to the organs, but in conditions of a lack of nutrients. Most often it occurs with regular fasting and diabetes.

reloading

It is considered a consequence of heavy physical exertion. In the process of strong training, the cells actively work, consuming oxygen. But such a state does not carry a hidden danger.

mixed

This is a very serious type that appears with serious lesions of various organs. For example, severe poisoning, coma.

Acute

The course of its development is rapid and is accompanied by terrible changes in the body. It requires immediate elimination in order to save the organs from exhaustion.

Doctors consider acute hypoxia to be much more dangerous than chronic, since it can make a disabled person out of a person in a short period of time.

Chronic

It can last for months as an accompaniment to various ailments. In this case, the changes are carried out rather slowly. The body has time to get used to, and the organs can continue to function as well.

Symptoms

It is possible to recognize the signals of hypoxia only in its three types: acute, subacute and chronic. The lightning-fast type most often ends in death.

• Acute lasts 2-3 hours, and during this time the number of heart contractions decreases, pressure drops, the rhythm of inhalations and exhalations changes. If this condition is not eliminated, then the person falls into a coma, and a fatal outcome is possible.
• Subacute and chronic forms are characterized by the occurrence of severe hypoxic syndrome. Against its background, symptoms from the central nervous system, necrosis, hemorrhage become noticeable. Because of this, a person is in a state of euphoria, suffers from anxiety in the area of ​​the musculoskeletal system.

If hypoxia progresses, then the following symptoms may appear:

1. lethargy;
2. headache;
3. tinnitus, dizziness;
4. nausea, vomiting;
5. convulsions.

Convulsions occur under the influence of third-party factors. In this case, it all starts with small twitches of the muscles of the face and goes to the arms and legs.

A person may feel pain in the region of the heart, shortness of breath, tachycardia, and a decrease in temperature. Subsequently, the pressure rapidly drops to 20-40 mm Hg. Art., death occurs.

Fetal hypoxia

Through the placenta, the baby receives a minimum amount of oxygen. The child, while still in utero, suffers from this difficult condition.

Most often, the causes are all kinds of mother's diseases: anemia, diseases of the liver, kidneys, heart.

Hypoxia in mild form does not have a negative effect on the fetus. But moderate and severe can lead to undesirable consequences in terms of the development of the baby: necrosis, defects, premature birth.

Absolutely at any stage of pregnancy there is the possibility of hypoxia. When the fetus is exposed to this condition in the first trimester, there is a great risk that abnormalities incompatible with life will appear. If we are talking about the third and second trimester, then damage to the central nervous system may occur. In the future, there will be a delay in development.

Hypoxia is not a separate ailment, but only part of one serious disorder. Having seen its first signs, one should look for the true causes that led to oxygen starvation.

There are also acute and chronic fetal hypoxia. For the acute form, an urgent treatment has been developed that saves the fetus from death. Chronic is able to accompany a woman throughout her pregnancy, exerting her devastating effect on the child. As a result, he is born weak and with vices.

Pathology can be recognized by a significant decrease in its activity (less than 10 shocks per day) and the appearance of bradycardia - below 70 beats per minute.

These signs allow each woman to independently feel when there is a lack of oxygen to the child. A more accurate check is given by the doppler of the vessels of the placenta, CTG, ultrasound.

Newborn

The concept of "hypoxia of the newborn" is not used in science. But it is often used to determine the condition of a child born from a medical point of view and to identify a possible hypoxic lesion.

Hypoxia of newborns is understood as oxygen starvation of the baby in childbirth or during a gestation.

Doctors try to assess the severity of hypoxia on the Apgar scale. It consists of 5 factors that should be recorded immediately after birth and after 5 minutes. In the end, everything is calculated by summation. The child teaches his assessment.

A strong child, respectively, can get a score of 8-10 points. If there is moderate hypoxia - 4-7 points immediately after birth. When, five minutes later, a score of 8-10 points is already put, it means that hypoxia has passed, and the child has managed to renew his strength. But if the Apgar score is 0-3 points, we have one of the most severe forms of hypoxia, respectively, the child is immediately transferred to the intensive care unit.

If the baby with fixed intrauterine hypoxia 5 minutes after birth receives a score of 7-10 points, and then grows without deviations, then drug therapy is not needed. He managed to overcome his oxygen starvation. If there are still violations, they must be treated.

What threatens

Hypoxia often gives complications that depend on the duration of fasting. If it is possible to eliminate it before the exhaustion of compensatory functions, the organs and tissues completely return to their original appearance and begin to work.

The duration of this period directly affects the degree of damage to organs, especially the brain. It can withstand without oxygen only 3-4 minutes, then necrosis appears. The liver, kidneys and heart muscle can last a little more - 30-40 minutes.

Oxygen deficiency in the brain causes problems in the functioning of the nervous system. Then there is a neuropsychic syndrome and dementia. The main thing is to choose the right complex method of rehabilitation.

Undesirable results include not maintaining physical exertion, all kinds of hemorrhages.

Treatment

Most often in practice there are combined types of hypoxia. Therefore, treatment must be comprehensive.

To maintain the required level of oxygen, doctors use hyperbaric oxygen therapy. It is based on the supply of oxygen to the lungs under pressure, which is specially set by specialists.

Due to this, oxygen through the blood is supplied directly to organs and tissues. This technique makes it possible not only to provide organs with oxygen, but also to slightly expand the vessels of the brain and heart.

As an addition, drugs are actively used to help increase blood pressure. If necessary, a blood transfusion will be needed.

For example, during hemic hypoxia, the following actions are actively carried out:

• Oxygen carriers are introduced;
• hemosorption, which makes it possible to remove poisoning products from the blood;
• drugs that perform the functions of respiratory chain enzymes are introduced;
• glucose is introduced, which provides the necessary energy;
• steroid hormones are used.

It is allowed to use any treatment methods that can at least a little help in revitalizing the former functions of organs and systems.

How to avoid

Prevention should be aimed at avoiding positions that can cause oxygen starvation. To do this, you must not forget about an active lifestyle, long walks, physical activity, proper nutrition and timely treatment of chronic ailments.

When working in closed offices, you should remember about regular ventilation, which will make it possible to saturate the air with oxygen and get rid of unnecessary carbon dioxide.

Conclusion

Conclusion

Noticing at least some symptoms of hypoxia, you should immediately seek help from doctors. The time gained in this condition can save a life. The main thing to remember is that this is not a disease, but a special condition. There are many different reasons for the occurrence of hypoxia, it is imperative to find and eliminate them.

Hypoxia (oxygen starvation)

Oxygen starvation in medicine has the term - hypoxia. Such a pathology is not considered a disease or syndrome, it is a condition in which the body receives less oxygen. There are different forms of hypoxia. The consequences of the reaction of the body depend on the type of pathology.

oxygen starvation

The cells of the human body for the normal functionality of organs and systems must be constantly saturated with oxygen. If this process fails, then it cannot do without consequences.

Not everyone has a correct understanding of what it is: hypoxia. Most people believe that oxygen starvation can only occur if a person is deprived of the opportunity to breathe for a long time, but this is not entirely true. Oxygen deficiency is also possible for internal reasons.

Lack of oxygen most often causes a disease such as hypoxia of the heart. A feature of the pathology is the defeat of the ventricles of the heart. With hypoxia of the heart, a stroke or myocardial infarction often occurs.

In medicine, there is a special term - myocardial hypoxia (GM). The pathological process affects the right or left ventricle. The main reason is the lack of oxygen in the tissues of the heart. The consequence of GM is cell death (necrosis).

The reasons

Various reasons can provoke an insufficient supply of oxygen to myocardial tissue, including external factors and diseases associated with the transport of substances through the vessels.

There are five main groups of negative factors.

• exogenous- lack of air in the room. With a long stay in a room where "fresh" air does not enter, the likelihood of developing heart failure is high.
• Respiratory- violation of the intake of air through the respiratory tract from the outside. For example, suffocation or drowning.
• Histotoxic- violation of the absorption of oxygen by tissues due to poisoning with heavy metals or carbon monoxide.

• Circulatory- lack of substances resulting from blockage of blood vessels.
• mixed- the influence of several factors simultaneously or the sequential impact of several causes.

Hypoxia, according to statistics, is more often observed in men, but representatives of both sexes are susceptible to this pathology.

Attention! With oxygen starvation, it is important not to delay in providing medical care. The chance of death is quite high.

Signs of oxygen starvation

Symptoms of myocardial hypoxia can have completely different signs. At the same time, there is no significant difference in the defeat of one or the other ventricle.

Signs of oxygen deficiency of the heart depend on several factors:

• forms of pathology;
• severity;
• the duration of the anoxic state.

The hypoxic state can occur in several forms. It is on what type of pathological process is observed in the patient that the manifestation of symptoms and the method of treatment depend.

There are four forms:

• instant - occurs instantly in two to three minutes;
• acute - can develop from twenty minutes to 2 hours;
• subacute - progresses over three to five hours;
• chronic - the most moderate form, which can last for years.

The most dangerous is the instant form. As a rule, it is during its occurrence that an acute pathological lesion of the heart develops.

General signs

Symptoms of a pathological condition with a lack of oxygen have characteristic manifestations:

• increased and irregular heartbeat;
• fibrillation (appearance of ventricular or atrial flutter);
• constant feeling of weakness and fatigue;
• the appearance of shortness of breath or uneven breathing and others.

With oxygen starvation, the work of the heart is disturbed, therefore, the pathological condition is clearly displayed on the cardiogram.

Important! In the acute or instantaneous form of the pathology, attention should be paid to the symptoms preceding myocardial infarction (chest pain, panic attack, dizziness and rapid heartbeat).

Hypoxia: treatment

It is impossible to cope with myocardial hypoxia without determining the reasons for which an insufficient supply of oxygen to the body occurs (occurred).

Treatment can be carried out in several ways:

• drug therapy;
• surgical intervention;
• ethnoscience.

Surgical intervention is used only in extreme cases, when oxygen starvation is provoked by heart disease.

Therapeutic methods

Medical therapy involves taking medications. Medicines can be prescribed only by a doctor, after passing the diagnosis and determining the clinical picture.

To alleviate myocardial hypoxia, drug treatment includes taking the following groups of drugs:

• antihypoxants ("Mexidol", "Neoton", "Mildronate", etc.);
• sedatives;
• calcium blockers;
• blockers.

Medications help reduce the intensity of symptoms and help normalize metabolic processes.

Blood transfusion and plasmapheresis are also used. The essence of these procedures is the introduction into the body of "renewed" (new) blood, saturated with oxygen.

Folk methods

In cases where the oxygen starvation of the cardiac system does not have a significant degree of insufficiency, it is possible to use the recommendations of traditional medicine together with medical methods.

With myocardial hypoxia, treatment is carried out with folk remedies that contribute to the normalization of the vascular system. The main remedy that has proven itself on the positive side is hawthorn tincture.

• tinctures of wild rose, wood lice or lingonberries;
• natural birch sap (taken at 0.5 liters per day);
• tea with linden or lemon balm.

Folk methods include:

• getting rid of bad habits;
• regular walks in parks, forests, etc.;
• adherence to a diet that reduces the amount of cholesterol in the blood.

People suffering from hypoxia or who are in the period of rehabilitation after sudden oxygen starvation are recommended complete calm, climate change (when living in an urban area) and trips to sanatoriums located in ecologically clean areas. A trip to the sea will also be useful.

Oxygen plays a vital role, and its deficiency leads to irreversible consequences. This element is involved in the creation of energy, and its lack leads to a stop of vital processes.

Hypoxia - what is it? This is the scientific name for oxygen starvation, that is, a condition in which oxygen deficiency occurs in tissues. Lack of oxygen can be within moderate limits for life, but also lead to irreversible consequences.

Hypoxia is an insufficient supply of oxygen to the body or a violation of the order of utilization of carbon dioxide due to oxidation.

Most sensitive to lack of oxygen:

• central nervous system;
• myocardium
• kidneys;
• liver.

These parts of the human body require the most energy, and oxygen deficiency leads to disruption of their work.

Important! The most dangerous for the body are hypoxia of the brain and heart. Myocardial hypoxia can develop rapidly, which leads to tissue necrosis, that is, their death. The lack of oxygen worsens the work of the heart rhythm, the left and right ventricles begin to work differently, trying to balance the lack of oxygen. All this causes ventricular fibrillation, a life-threatening condition.

Oxygen starvation, depending on the cause, happens:

• exogenous;
• respiratory;
• blood;

The brain is the first organ to suffer from lack of oxygen.

• circulatory;
• histotoxic;
• reloading;
• mixed;
• technogenic.

Exogenous oxygen starvation is experienced by lovers of mountain hiking. This type is caused by a change in air pressure during inspiration (a large difference between the pressure in the lungs and in the external environment). The respiratory variety is caused by a poor supply of blood from the lungs to the blood vessels. This is often the case with smokers. Blood hypoxia is a common occurrence for owners of anemia. It is also associated with carbon monoxide poisoning. And overload hypoxia is familiar to those who are engaged in heavy physical labor.

According to the rate of development, hypoxia happens:

• lightning fast;
• acute;
• chronic.

Lightning develops rapidly, so the elimination of its causes should be just as fast. Acute - typical for post-infarction conditions and after a large loss of blood. Chronic accompanies heart diseases, such as, for example, heart disease and cardiosclerosis.

The result of hypoxia is the cessation of the functioning of all organs and systems in a matter of seconds from the moment the oxygen starvation of the body begins.

Signs of oxygen starvation

The most difficult thing to diagnose oxygen starvation is to determine it. The symptoms are often too vague. One of the typical signs of oxygen starvation is a sharp excitation of the nervous system up to a state of euphoria, followed by a sharp depression and apathy. During excitation, voluntary movements of the body are observed (anxiety for no reason, twitching of the collar, etc.), a violation of the normal rhythm of the heart and breathing (noticeable on the cardiogram - frequent and uneven heart contractions are observed). When the excitation abruptly passes, the skin becomes too pale, cold sweat appears on the forehead, “flickers” appear before the eyes.

The body tries to "rescue":

• paralysis of a group of muscles develops by increasing their tone;
• various protective reflexes appear and disappear;
• the body "turns off" some functions, which causes loss of consciousness.

Attention! With lightning-fast hypoxia, coma can occur 1–2 minutes after loss of consciousness.

In the first 15 seconds, a stoppage of brain activity occurs, and the person falls into a coma.

With myocardial hypoxia, there is a rapid work of the heart, with inactivity, it can also stop completely, which will lead to a lack of oxygen in the brain.

It is important to remember that the sooner first aid is provided, the less consequences for the body.

Quite typical for hypoxia symptoms are also:

• headache;
• hysterical state (when you want to laugh and cry at the same time);
• memory impairment and disorientation;
• aggressiveness and deterioration of mental activity;
• violation of sleep, vision, speech.

Treatment of hypoxia

Oxygen starvation can even lead to death, so when observing the first symptoms, it is important to provide first aid:

• provide access to fresh air;

The consequences of hypoxia depend on the rate of development of oxygen starvation

• unfasten clothing that restricts breathing;
• to do artificial respiration and in case of cardiac arrest - an indirect heart massage.

Important! Treatment depends on the underlying cause. Therefore, if necessary, stop the bleeding, ventilate the room, free the lungs or airways.

Sometimes the elimination of hypoxia comes down to a regular walk in the fresh air, but if the cause is a heart, kidney disease, or a malfunction of the brain or liver, then the treatment of oxygen starvation should be more serious. For each type, the necessary measures are quite diverse:

• lung ventilation;
• the use of bronchodilators, analeptics and antihypoxants;
• use of oxygen concentrates;
• blood transfusion;
• heart surgery for myocardial hypoxia.

Drug treatment of myocardial hypoxia

It should be remembered that different drugs are used to treat different types of drugs.

Treatment of cerebral hypoxia is directly subordinated to the causes of

Important! Do not self-medicate. Cardiac drugs should be prescribed only by a cardiologist.

All drugs that eliminate hypoxia are called antihypoxants. They are divided into three groups:

• direct type;
• indirect type;
• mixed.

Direct acting antihypoxants are first aid drugs for cardiac hypoxia. They stimulate energy processes in the heart muscle instead of the missing oxygen (for example, Mexidol, Neoton, Piracetam).

Indirect antihypoxants put the heart into a calmer state where it consumes less oxygen. However, this is an emergency remedy, as it can impair brain function. An excellent example of such drugs are sleeping pills and anesthetics.

Mixed antihypoxants combine the previous two types, but also contain vitamins.

Treatment of myocardial hypoxia with folk remedies

Folk remedies can only be an additional treatment in the chronic form, but by no means the main method of treatment and be used in other forms.

Beneficial effects on the work of the heart have:

• hawthorn;
• arnica;
• nettle;
• black currant;
• viburnum fruits;
• cowberry;
• ginseng;
• ginger;
• gingko;
• marshmallow;
• anise.

It is these plants that help to maintain cardiac function in a normal state.

Oxygen starvation or brain hypoxia is a severe pathological condition of the human body, in which insufficient oxygen enters the cells.

Causes of hypoxia:

1. various diseases of the body;
2. circulatory disorders;
3. paralysis of the respiratory muscles;
4. shock conditions;
5. heart and vascular insufficiency, heart block;
6. asphyxia;
7. alcohol;
8. carbon monoxide poisoning;
9. postoperative complications;
10. prolonged stay of a person in a gassed or stuffy room, at great depths or heights.

Regarding the rate of development, hypoxia happens:

Oxygen starvation is the cause of severe pathologies of the brain, heart, liver, kidneys. Severe hypoxia can lead to coma or death. Therefore, it is so important to take care of your health and in order to prevent or treat brain hypoxia, do not postpone a visit to the doctor.

What is oxygen starvation?

Oxygen is a vital element for our body. It is involved in complex biochemical processes at the cellular level. Briefly, this process can be described as the synthesis of energy. And we need energy for everything: for the functioning of organs and systems (for example, the work of the heart, contraction of the intestinal walls), for our mental and physical activity.

With oxygen starvation, our body receives less energy - this is chronic tissue hypoxia. The function of the affected organ is impaired. And in especially severe cases, tissues do not receive energy at all - in case of poisoning, asphyxia.

What happens during oxygen starvation?

It is not for nothing that experts call the brain a “critical organ” during hypoxia. After the cessation of blood supply, the dynamics of brain dysfunction is as follows:

Only 4 seconds in acute oxygen deficiency is able to withstand the brain tissue without disrupting activity.

With prompt qualified assistance, the state of coma can be reversible.

Signs of hypoxia

Signs of oxygen starvation depend on the type and causes of hypoxia. At an early stage, signs of hypoxia are subtle, but can have irreversible consequences.

Classification of types of oxygen starvation regarding the causes:

1. Exogenous hypoxia. It occurs as a reaction to low oxygen content, at low pressure, in stuffy rooms, when climbing to a height.
2. Hemic hypoxia- this is a lack of oxygen in the blood, for example, with anemia.
3. Respiratory hypoxia. Occurs when the body's ability to receive oxygen is impaired due to the pathology of the respiratory system.
4. Circulatory hypoxia associated with CVD pathology.
5. tissue hypoxia. It develops if oxygen is not absorbed by the tissues of the body.
6. Overload hypoxia. It can occur as a result of intense physical activity, when the body's need for oxygen increases.
7. Mixed hypoxia- prolonged oxygen starvation of a severe form with a combination of several reasons.

General signs of oxygen starvation.

With timely provided, adequate medical care, all body functions are restored.

Symptoms of oxygen starvation

They are quite varied and typical:

1. A sharp headache resulting from a pressure drop or lack of oxygen in the room.
2. A state of distraction and disorientation after a sudden deterioration in memory. Often the patient cannot understand where he is. Unable to remember where he went. This state does not last long. When it passes, the person calms down, attributing these symptoms to overwork or starvation.
3. A sharp transition from a state of excitement, euphoria, an increase in adrenaline to a state of lethargy and lethargy. There is a rapid heartbeat, dizziness, cold sweat, convulsions.
4. Involuntary and uncontrolled actions of the limbs, impaired skin sensitivity, lethargy, sensation of pain in the arms and legs.
5. Frequent mood swings, falling into extremes, the desire to laugh and cry for no particular reason.
6. Sleep disturbance, insomnia, awakenings in the middle of the night.
7. Aggression, irritability, weakness against the background of general fatigue of the body. A person cannot concentrate on a particular job.
8. Speech and vision impairment.
9. Decrease in mental abilities, difficulties with assimilation of new information.

By ignoring the symptoms of oxygen starvation of the brain, you are putting your health at serious risk. Timely access to specialists, early diagnosis and proper treatment will help prevent serious complications.

Hypoxia research methods:

Treatment of oxygen starvation

Brain hypoxia is a serious pathological condition of the body, so treatment should be carried out at the first symptoms. Timely treatment will prevent negative consequences and avoid complications.

The treatment of oxygen starvation depends on the causes of the disease, by eliminating which positive dynamics can be achieved.

Emergency help for hypoxia.

If signs of hypoxia appear before the doctor arrives, it is important to provide the patient with fresh air and, if necessary:

• unfasten clothes;
• to remove water from the lungs;
• ventilate a smoky or stuffy room;
• remove the patient to fresh air;
• do artificial respiration.

Doctors provide therapy, saturation of the body with oxygen, blood transfusion, resuscitation.

Treatment methods depend on the causes and types of hypoxia. In some cases, it is enough to ventilate the room and walk in the fresh air.

Depending on the severity of the patient's condition, treatment can take place in a hospital or at home. To normalize the patient's condition, medications and vitamins are prescribed.

Serious treatment will be required if the causes of oxygen starvation are problems of the heart, kidneys, blood, lungs. Therefore, the establishment of the work of the cardiovascular system, respiration, correction of the acid-base state of the blood, water-salt balance is of great importance.

1. In the case of exogenous hypoxia, oxygen equipment will be needed.
2. With respiratory hypoxia, one cannot do without bronchodilators, respiratory analeptics, antihypoxants.
3. In some cases, artificial lung ventilation, oxygen concentrators are used.
4. Treatment of hemic hypoxia requires blood transfusion.
5. In the treatment of circulatory hypoxia, corrective operations on the heart and blood vessels are used.

Prolonged oxygen starvation can cause cerebral edema, requiring the appointment of decongestants. With untimely resuscitation, fulminant and acute hypoxia often lead to death. Therefore, preventive measures, early diagnosis and timely complex treatment of hypoxia are so important.

Prevention

To prevent hypoxia, it is necessary to eliminate all the causes that lead to a lack of oxygen.

1. Frequent walks in the fresh air - better outside the city or in the park.
2. If you have to stay indoors for a long time - frequent ventilation at any time of the year.
3. Periodic preventive examinations by specialists - for the early detection of diseases and their timely treatment.
4. Sufficient physical activity.
5. Prevention of beriberi: the use of fresh fruits and vegetables all year round. If necessary - taking vitamin and mineral complexes in courses.
6. Exclusion of smoking, drinking alcohol.

Which doctor should I contact with oxygen starvation?

It all depends on the course of the process. If this is chronic oxygen starvation, then usually the cause is heart or blood disease. Accordingly, the cardiologist or therapist is engaged in the correction. And if the brain suffers, a neurologist is connected to the treatment.

Acute or fulminant hypoxia, as well as severe chronic hypoxia, require urgent resuscitation measures. Therefore, in these cases, you need to immediately call an ambulance.

• Pulse oximetry. The method is accessible and simple - just put a pulse oximeter on your finger. Blood oxygen saturation is determined within a few seconds. The norm is at least 95%.

• Determination of acid-base balance (ASCHR) and blood gas composition.

• Capnography, CO-metry– study of gases of exhaled air.

• Laboratory and instrumental methods studies can establish the fact of hypoxia, but to establish its causes, an additional examination, individual for each patient, will be needed.

Oxygen is an active element, in the absence of which the vital activity of the human body stops within a few minutes. We will talk about what oxygen starvation is, called hypoxia. Hypoxia is an insufficient supply of oxygen to the body or a violation of the order of utilization of carbon dioxide due to oxidation. The continuous process of providing the human body with oxygen occurs due to the respiratory system and the transport elements of the blood flow. The first organ to suffer from lack of oxygen is the brain. Therefore, brain hypoxia will be the subject of the article.

More about oxygen starvation

So what is hypoxia? It is difficult to overestimate the importance of O2 for people. The result of hypoxia is the cessation of the functioning of all organs and systems in a matter of seconds from the moment the oxygen starvation of the body begins.

The consequences of hypoxia for any living organism are critical. In the first 15 seconds, a stoppage of brain activity occurs, and the person falls into a coma. With each new second of brain hypoxia, irreversible processes develop. And after 3-4 minutes, the brain stops functioning in adults, in other words, its death.

Types of hypoxia depending on the rate of development, table:

How does oxygen starvation of the brain manifest itself:

1. The phase of increased excitability is expressed in the inability to fully control one's actions, movements, facial expressions.
2. The appearance of cold sweat, perspiration indicates the body's attempts to cope with the consequences of hypoxia.
3. The unnatural shade of the skin covers immediately attracts attention. As a rule, there is hyperemia of the face, that is, pronounced redness. Or the skin becomes pale with a bluish tinge.
4. Inhibition from the side of the central nervous system is expressed in damage to the brain structures responsible for hearing, vision, and articulate speech. Hypoxia of the brain causes disturbances of these functions all at the same time or any one of them. In this case, the patient may complain of signs of oxygen starvation, such as darkening in the eyes, dullness of hearing, tinnitus, and others.
5. Loss of unconditional and conditioned reflexes, such consequences of oxygen starvation, are caused by cerebral edema due to perinatal hypoxia.

With a high sensitivity of the brain to hypoxic lesions, a person can fall into a coma. Disabling the main control center as a result of brain hypoxia entails cardiac arrest, blood circulation and complete cessation of the body's vital activity. It is now clear why even a short-term or limited lack of oxygen access to the lungs should not be allowed.

Consequences of cerebral hypoxemia

Why is brain hypoxia dangerous? The consequences of hypoxia depend on the rate of development of oxygen starvation. Instantaneous, subacute and acute stages in the vast majority of cases end in death. The exception is situations when the patient receives resuscitation assistance in the first seconds. What is the danger of oxygen starvation in the chronic form is determined by the area of ​​\u200b\u200bdamage to the brain matter.

The most common chronic hypoxia consequences:

• Vomiting, nausea.
• Dizziness, clouding of consciousness up to its loss.
• Violations of speech, auditory, visual functions.
• Systematic pain in the head.

If the patient at the time of brain hypoxia was provided with highly professional assistance, treatment and a course of rehabilitation and preventive measures were carried out. Then a complete restoration of brain activity is possible. But when chronic hypoxia of the brain accompanies a person for a long period of time and no measures are taken to cure the pathological condition. That such a development of events usually threatens with serious consequences. And even in the case of the start of belated therapy for brain hypoxia, it is unlikely that it will be possible to fully restore the previous state, the consequences of oxygen starvation will still be traced.

Causes of asphyxia of the brain

Oxygen starvation of the brain is not a disease, but a pathological state of hypoxia, the causes of which can be both external and internal. Brain hypoxia can occur not only due to the cessation or restriction of oxygen access, but also due to a violation of the process of removing carbon dioxide from the body.

But also the causes of hypoxia can be associated with blood pathologies and, first of all, a lack of hemoglobin.

Causes of oxygen starvation associated with any pathologies and circumstances of restricting air intake:

• Various types of anemia.
• Atherosclerotic changes in blood vessels.
• Pathologies of the larynx, such as swelling or spasm of the throat.
• Prolonged stay in a room that is not ventilated.
• Gas intoxication.
• Allergic reaction to alcohol intake.
• Complications after the operation.
• Stress, accompanied by a decrease in blood pressure.
• Heart failure or sudden cardiac arrest.
• Stroke, resulting in an acute lack of oxygen in one or both hemispheres of the brain.
• Asphyxia, paralysis or pathology of the respiratory organs.

Etiological types of hypoxia:

• Exogenous (hypoxic origin) - occurs in a poorly ventilated, closed room, as well as at reduced atmospheric pressure while climbing to a great height.
• Respiratory (respiratory system) - occurs as a result of diverse violations of the oxygen flow through the paths of the respiratory organs.
• Circulatory (cardiac system) is detected as a result of circulatory pathologies. It is divided into the general circulatory type of hypoxia, in which the supply of oxygen masses to the organs and systems of the body is disrupted. And a local version of oxygen starvation in case of local disruption of oxygen supply.
• Tissue (histotoxic) is formed when tissue processes fail, as a result of which oxygen is absorbed by them.
• Blood (hemic) occurs when hemoglobin is completely or partially destroyed by carbon monoxide or oxidizing agents.
• Mixed there is a combination of several varieties of hypoxia.
• Overload appears when there is a lack of oxygen due to excessive physical exertion.

Symptoms of asphyxia of brain tissue

The symptoms of oxygen starvation of the brain differ depending on the reasons that caused it. But, despite the similarity, there are still minor differences in the symptoms of brain hypoxia, which occur in acute or chronic form.

Acute hypoxia symptoms are characterized by two stages:

1. Overexcitation of the central nervous system, expressed in rapid breathing and heartbeat, there are all signs of hypoxia - this is euphoria, perspiration and sticky sweat, a sharp headache. The state of overexcitation lasts for seconds, after which it is replaced by depression of the central nervous system up to loss of consciousness.
2. Depression of the nervous system is accompanied by symptoms of hypoxia, such as weakness, flashing of black dots in the eyes, drowsiness, dizziness, general apathetic state of health. Before coma occurs, the patient may experience a partial impairment of consciousness, accompanied by stupor, somnolence or stupor. Without resuscitation support, the patient's superficial reflexes fail in a matter of minutes, and after them, deep reflexes - the heart and breathing stop.

The clinical picture of oxygen starvation of the brain symptoms:

• Unreasonable mood swings.
• Decreased mental productivity.
• Deterioration of memorization with increasing progression.
• Deviations in coordination of movements and speech.
• Loss of concentration and fatigue.
• Weakening of mental activity, dementia.
• Inability to adequately respond to newly received information.
• Depression and other psychoses (irritability, resentment, tearfulness).
• Difficulty falling asleep at night, accompanied by daytime sleepiness.

Cerebral oxygen starvation symptoms are not specific to hypoxemia. The above signs of chronic hypoxia may accompany other pathologies. But in any case, the attending physician must check in each case whether there is a place for cerebral hypoxia.

Treatment of cerebral hypoxemia

How to treat cerebral hypoxia? Treatment of cerebral hypoxia is directly subordinate to the causes of occurrence. In addition to resuscitation, in case of acute oxygen deficiency, there is also a standard hypoxia therapy regimen.

It consists in taking a number of drugs aimed at treating pathology, eliminating the causes and consequences of oxygen starvation of the brain.

To cure hypoxemia of the brain, drugs are prescribed:

• Nootropic.
• Eliminating headache.
• Normalizing blood circulation.
• Regulating vascular tone.
• Thinning blood.
• Bronchodilator.
• Anti-atherogenic.
• Iron-containing.
• Antidepressants and sedatives, as well as sleeping pills.
• Fortifying and vitamin complexes.

Medicines undoubtedly have a therapeutic effect, but without a healthy lifestyle, recovery will be incomplete with the likelihood of a relapse of the pathology. The diagnosis of chronic hypoxia of the brain requires a revision of the diet and daily schedule. As a preventive measure for oxygen starvation, breathing exercises are recommended, running, jumping or just walking is also suitable, preferably as fast as possible. The main rule of successful therapy and prevention is systematic.

Hypoxia, or in simple terms - oxygen starvation of the brain, is a serious disease that requires diagnosis and treatment. Hypoxia blocks the supply of oxygen to the nerve junctions. In the case when there are no symptoms of impaired functioning, the brain can withstand 4 seconds of acute hypoxia, already a few seconds after the cessation of blood supply, the person loses consciousness, after 30 seconds, the person falls into a coma.

The most serious outcome in this violation is the death of a person. Therefore, it is important to know the main causes of oxygen starvation of the brain and the symptoms that will help identify the first signs of a violation and avoid serious consequences and long-term treatment.

There are 3 types of hypoxia:

• Fulminant hypoxia - development occurs quickly, within a few seconds and minutes;

• Acute hypoxia - lasts for several hours, the cause may be - a heart attack, poisoning;

• Chronic insufficiency - develops for a long time, the causes are heart failure, cerebral atherosclerosis, heart disease.

Causes of oxygen starvation

Oxygen deficiency of the brain can be caused by several reasons:

1. Respiratory - the brain is not able to get the proper amount of oxygen, due to a violation of the respiratory processes. Examples include diseases such as pneumonia, asthma, chest trauma.

1. Cardiovascular - a violation of blood circulation in the brain. Causes may be: shock, thrombosis. Normalization of the work of the heart and blood vessels, helps prevent the development of a stroke of the brain.

1. Hypoxic - oxygen starvation, which occurs when oxygen in the air decreases. The most striking example is climbers, who, when climbing uphill, most clearly feel the lack of oxygen.

1. Blood - with this factor, oxygen transport is disturbed. The main reason is anemia.

1. Tissue - development occurs due to a violation of oxygen transport. The cause may be poisons or drugs that could destroy or block enzyme systems.

Main symptoms

Symptoms of a lack of oxygen in the brain can manifest themselves in different ways for each person. In one patient, sensitivity may decrease, lethargy may appear, in another, headaches may begin.

The main symptoms of oxygen starvation of the brain:

• Dizziness, the likelihood of loss of consciousness due to inhibition of the activity of the nervous system. The patient has severe bouts of nausea and vomiting;
• Blurred vision, darkness in the eyes.
• Change in skin color. The skin becomes pale or red. The brain reacts and tries to restore the blood supply, resulting in a cold sweat.
• Adrenaline rises, after which muscle weakness and lethargy occurs in the patient. A person ceases to control his movements and actions.
• Irritability, resentment appear, depression and other mental disorders develop.
• Inattention, the patient is hard to absorb information, reduced mental performance.

The final stage of the disease with oxygen starvation is the development of coma, and then soon the respiratory and cardiac arrest.

If the patient is provided with timely medical care, all body functions can be restored.

Diagnosis and treatment

To determine the current condition of the patient and whether he is really sick, a series of medical studies is required.

They include:

• Magnetic resonance imaging of the brain. This method shows the consequences of oxygen deficiency. With this method, you can see the areas of the brain where sufficiently saturated oxygen is supplied.

• Ultrasound - the method allows you to determine the deviation from the norm during the development of a child in the womb. Allows you to determine oxygen starvation at the initial stage.

• Complete blood count and clinical tests for acid-base balance.

• General and selective angiography.

Treatment of oxygen deficiency, first of all, consists in restoring the required supply of oxygen to the brain.

With a lack of oxygen in the brain, the following measures are prescribed:

• Maintaining the normal functioning of the cardiovascular and respiratory systems;
• Drugs to improve blood circulation in the brain;
• Antihypoxanes;
• Decongestants;
• Bronchodilator drugs.

Radical treatment of the disease is also carried out when the patient is already in serious condition. Such treatment includes: blood transfusion, installation of an oxygen mask, procedures for resuscitation of the patient.

Prevention of hypoxia

Preventing a disease is always easier than treating it. For a normal supply of oxygen to the body, you just need to follow the recommendations of experts. These tips can be used both for the prevention and treatment of oxygen deficiency.

The main tips include:

1. Fresh air . Walks should take at least 2 hours, preferably before going to bed. It is better to take walks in ecologically clean places (parks, forests).

1. Sport. Light exercise in the morning promotes better blood circulation, and if you also do it on the street, the effect will be doubled.

1. Correct schedule. It is required to normalize your regimen, take the required time for rest and sleep. To normalize the processes in the body, sleep should be given at least 7-8 hours. Do not forget to warm up if you work at the table.

1. Proper nutrition. For the normal supply of oxygen to the brain, nutrition plays an important role. The diet should consist of a large number of vegetables and fruits. You should eat foods rich in iron (buckwheat, meat, dried fruits), while dairy products and coffee consumption should be minimized.

1. Lack of stress. Try to avoid stressful situations and not be nervous in vain.

Respiratory prevention of oxygen deficiency

One of the most convenient and simple ways to prevent the disease is breathing exercises. This method is very easy to use and does not require any additional effort.

A few useful exercises to keep in mind:

1. Relax completely, you need to take a 4-second deep breath, then hold your breath for the same time and exhale slowly. Repeat about 12-15 times. After 1 month, increase the time of inhalation and exhalation.

1. Inhale deeply and take at least 6-7 short exhalations through the nose. The mouth remains closed. Repeat 3-4 times.

It is advisable to repeat these exercises 2 to 4 times a day.

Oxygen starvation in newborns

Symptoms of a lack of oxygen in the brain can occur in a newborn during the period when the baby is still in the womb, so directly during childbirth. Hypoxia in a severe stage, not rarely, can lead to serious consequences for both the mother and the baby.

Of these, it can be noted:

• premature birth;

• Intrauterine death of a child;

• stillbirth;

• Severe disability of the child.

The reasons why these severe consequences in children can be caused:

1. Problems of the cardiovascular system;

1. Intrauterine infections;

1. Wrong lifestyle (alcohol, cigarettes, drugs);

1. Fetal pathology;

1. Birth trauma.

Oxygen deficiency, as a diagnosis, is made in about 15% of pregnancies.

Most often, brain hypoxia in a child develops as a result of the mother’s improper lifestyle, alcohol consumption, and smoking.

Therefore, in order for your child to grow up a healthy and strong child, you should give up bad habits.

The danger of brain hypoxia

The state of oxygen starvation can lead to pathological changes. Violated brain activity and basic functions of the brain.

Whether the prognosis will be favorable depends on the degree of brain damage, and at what stage the disease was discovered.

The chances of a person's recovery also depend on what state he is in at the moment. With a prolonged coma, the basic functions of the body are impaired and the chance of recovery becomes very low.

With a short-term coma, the chances of being rehabilitated are very high. In this case, the treatment may take sufficient time.

Oxygen is something without which our body cannot live for even a few minutes. All human organs without exception are sensitive to its deficiency. But, the most sensitive is the brain. Oxygen starvation, or hypoxia, after a few seconds leads to damage to its cells, after 20 seconds a person falls into a coma, and after 4 minutes brain death occurs. Therefore, it is so important to understand why oxygen starvation of the brain occurs and what hypoxia can lead to.

Depending on how quickly oxygen starvation develops, hypoxia happens:

• Acute. The occurrence of obstructions to the blood supply to brain tissue. It can appear as a result of large blood loss, poisoning or a heart attack.
• Chronic. May occur in patients with cardiosclerosis, heart failure and other heart diseases.
• Lightning. Develops rapidly. The duration of such a phase of hypoxia can last several seconds or minutes.

Depending on what caused the violation, the following forms of hypoxia are distinguished:

1. Exogenous. Occurs when a person breathes air with a low amount of oxygen.
2. Respiratory. The reason is various disturbances in the work of the body, which prevent the supply of the amount of oxygen necessary for the brain.
3. Circulatory. Disorders in the work of the heart or blood vessels can lead to this form. characterized by rapid development.
4. Fabric. It appears due to a violation of the absorption of oxygen by the tissues of our body.

Cellular tissue hypoxia is characterized by a certain cyclicity. You can understand this by reading this diagram.

1. Hemic. It is a consequence of a decrease in the amount of oxygen dissolved in the blood.
2. Reloading. Occurs in people when the amount of oxygen that enters the body does not fully satisfy its need. It can be observed during heavy physical exertion.
3. Mixed. Most often it develops gradually and can have serious consequences. It arises as a result of a whole complex of negative factors.

Causes that provoke oxygen starvation of the brain

The most common causes of hypoxia in adults are:

• Stroke, which results in an acute oxygen deficiency in one of the hemispheres of the brain.
• Stressful situations, accompanied by a decrease in blood pressure.
• Anemia.

• Osteochondrosis.
• Prolonged stay in a closed, unventilated room or when climbing to a great height (in the mountains).
• Gassing.
• Cardiac arrest, which leads to the cessation of oxygen supply to the brain tissue.

• Heart failure.
• Paralysis or respiratory disease.
• Suffocation.

How to give first aid to a person with suffocation. In such cases, it will not be possible to wait for the arrival of doctors, you need to act immediately

• Various circulatory disorders of the body.
• Reaction to alcohol.
• Complications after surgery.
• Diseases of the nervous system.
• An allergic reaction that contributed to the development of laryngeal edema.

Symptoms of the disease

Cerebral oxygen starvation in adults has standard symptoms that often help with the diagnosis. These include:

1. Increased excitability, which was not observed before. A slight oxygen starvation of the brain provokes a state of euphoria, a person may not control his behavior. Excitability is replaced by lethargy and a feeling of depression.
2. Sharp headache. Most often it has a pressing character.
3. Arrhythmia and tachycardia.

Learn more about the causes and symptoms of the disease from the doctor of medical sciences, professor, head of the department of cardiology of the Novokuznetsk State Institute Vladimir Matveyevich Podkhomutnikov:

1. Change in skin color. It becomes pale, may be too red or bluish. In such a situation, the brain tries to restore normal blood supply, which can be manifested by excessive sweating.
2. Inhibition of the nervous system, which is a manifestation of posthypoxic brain damage. In this case, the patient notes or indomitable vomiting. Along with this, vision may be impaired. Hypoxia provokes loss of consciousness.
3. Perinatal damage to the brain as a result of its oxygen starvation. This condition provokes, the patient's conditioned and unconditioned reflexes disappear. If the blood supply to the brain is not restored, then the functioning of all internal organs is disrupted, the skin stops responding to external stimuli.

It must be remembered that oxygen starvation manifests itself differently for everyone, therefore, having noted some of the signs in yourself, you need to consult a doctor who can make an accurate diagnosis and prescribe treatment.

Diagnosis of hypoxia

To make a diagnosis, laboratory and instrumental studies are carried out:

• Pulse oximetry. This diagnostic method is rightly called the most accessible way to determine cerebral hypoxia. To do this, the patient puts a special device on his finger - a pulse oximeter.
• Study of acid-base balance. The method is based on the analysis of blood composition, which makes it possible to evaluate the quantitative indicators of many body functions.
• Complete blood count (if you are a resident of St. Petersburg, then here http://medi-center.ru/laboratornaya-diagnostika/analizy-v-spb you can make an appointment).

To understand the results of your tests, you need to know the rules. The main norms for indicators of a general blood test for men and women are given in this table

• Electroencephalogram.
• Computed and magnetic resonance imaging of the brain.
• Reovasography.

You can see how the procedure for obtaining electrocardiogram data is in this figure.

Depending on the patient's state of health, the degree of hypoxia and the alleged cause of brain oxygen deficiency, the doctor will prescribe an individual diagnostic program.

Treatment of oxygen starvation of the brain

Before starting the treatment of oxygen starvation in adults, it is necessary to establish the exact cause that provoked this condition. Therefore, it is important for the patient to clearly articulate the factors that could lead to this. Most often in an adult it is smoking, alcohol abuse, prolonged stay in a poorly ventilated room.

After assessing the severity of oxygen starvation, the doctor will recommend treatment in a hospital or at home. The patient is prescribed drugs that stabilize the normal functioning of the body. It is also necessary to take medications, the action of which is aimed at restoring the normal blood supply to the brain tissues.

Sometimes it is enough for an adult to relieve the symptoms of mild oxygen starvation by ventilating the room in which he is located or going outside. The situation is different if the cause is some kind of disease or malfunction of the body.

If oxygen starvation provoked a disease of the blood, cardiovascular or respiratory system, the patient will need more serious measures to eliminate it.

1. With exogenous hypoxia, oxygen equipment (masks, pillows, etc.) is used.
2. For the treatment of respiratory hypoxia, analgesics, antihypoxanes and drugs that dilate the bronchi are used. Sometimes artificial lung ventilation is performed.

Remember that some analgesics have a negative effect on the body and are addictive. It is important to be able to distinguish which of them are narcotic and which are non-narcotic.

1. Hemic hypoxia requires blood transfusion, which contributes to the normalization of blood circulation.
2. With a circular form of oxygen starvation, surgical intervention on the heart or blood vessels is necessary.
3. Antidote drugs are used to treat the histoxic form.

If the patient consults a doctor in time and effective treatment is prescribed, the prognosis for recovery will be favorable. However, if oxygen starvation continues for a long period of time, irreversible consequences may develop that cannot be eliminated.

You can learn interesting facts about the disease from the pediatrician, family doctor Konstantin Borisovich Zabolotny:

Folk remedies for the disease

Along with traditional methods of treatment, folk remedies are often prescribed that help restore blood supply to brain tissues. Decoctions from the fruits of mountain ash, herbs of horsetail, motherwort, wood lice and periwinkle have proven themselves well.

As an example, we can give a recipe for a folk remedy from crushed leaves of wood lice. To prepare such a tincture, 1 tablespoon of herbs should be poured with 1 cup of boiling water, mix, cover the dish with a lid and leave to infuse for 7-8 hours. Take this medicine 50 ml 30 minutes before meals.

But it is worth noting that before taking any folk remedy, it is necessary to consult a doctor, as some of them can cause allergic reactions.

When making a prognosis for a patient, doctors are guided by the degree of damage to the brain tissue, which depends on how long the brain experienced oxygen starvation.

If the lack of oxygen did not last long, then the prognosis is usually favorable and the patient manages to eliminate its consequences. But if hypoxia has not been treated for a long time, it can lead to the development of a vegetative state. In this state, the patient retains the basic functions of the body (breathing, blood pressure, etc.), but the person will not respond to what surrounds him. As a rule, such patients live within 1 year.

Oxygen starvation in some patients leads to impaired appetite, the appearance of blood clots and the development of pulmonary infections.

Hypoxia in newborns

Oxygen deficiency in the brain tissues can occur in a newborn at any stage of its development: during childbirth or even during intrauterine development. Hypoxia is one of the most commonly diagnosed disorders in newborn babies.

In some cases, this condition is life threatening. If a severe form of the disease occurs, the baby dies or receives a severe disability.

The following factors can affect the appearance of oxygen starvation:

• Maternal disease, severe pregnancy and childbirth. The fetus may experience a lack of oxygen due to anemia or heart defects of the pregnant woman, premature detachment of the placenta or the presence of bleeding in her.
• Pathology of blood flow through the umbilical cord and violation of the placental-uterine circulation. This also includes entanglement with the umbilical cord, damage to its vessels, trophic disorders of the placenta, protracted or rapid labor, the use of special medical instruments (forceps, etc.).

Gynecologist Raisa Zanitullina talks about fetal hypoxia in this video:

• Genetic abnormalities in the fetus, anomalies in its development, Rh conflict, infectious diseases, congenital heart disease, skull trauma.
• Asphyxia, as a result of which the airways of the fetus partially or completely overlap.

After birth, the baby must be examined by a neonatologist, who can pay attention to the symptoms of oxygen starvation in a newborn. In this case, the crumbs observed tachycardia. Subsequently, it turns into arrhythmia and heart murmurs. A child who has undergone hypoxia may develop blood clots and numerous hemorrhages in tissues and organs.

Treatment of the disease in newborns

The treatment of children differs significantly from the treatment of adult patients. If there is a suspicion of a lack of oxygen in the fetus, doctors try to speed up the birth, but at the same time not harm the mother and baby. To do this, a caesarean section or the imposition of obstetric forceps can be performed. After removing the baby, everything possible is done to provide him with the necessary amount of oxygen.

During childbirth, doctors can use special drugs, the action of which is aimed at increasing blood circulation in the placenta and the human body. Also, a set of resuscitation measures is often used, which free the respiratory tract of the newborn from mucus, carry out artificial respiration.

Until the child's condition stabilizes, he is shown the introduction of such drugs: sodium gluconate, glucose solution, etimizol. In the future, a child who has undergone hypoxia should be under the supervision of a pediatrician and a neuropathologist, who will monitor his development and, if necessary, correct possible changes in the functioning of the body.

However, doctors are not always able to conduct effective therapy that would help the baby completely get rid of the effects of oxygen starvation. In this case, the child remains disabled. This leads to his lag in physical or mental development. Therefore, doctors always recommend that pregnant women carry out prophylaxis, which consists in rational nutrition, taking vitamins, frequent exposure to fresh air, and light physical exercises that will correspond to a specific gestational age.

Hypoxia is not a disease, but a condition that can be effectively treated. Only for this, it is necessary to identify the pathology in time and begin the correct treatment.

One of the most urgent problems in obstetrics and neonatology is fetal hypoxia during pregnancy. According to some data, its frequency among the total number of births ranges between 4 and 6%, according to others, it reaches 10.5%.

Pathology associated with hypoxia, that is, with a lack of oxygen, is dangerous not only in the prenatal period, but also leads to serious consequences in children in the future. In 63% of the associated pathological changes in the body develop in the prenatal period, on average in 21% - in the intranatal period and in 5-6% - already in the neonatal period. How to determine fetal hypoxia and can it be avoided?

What is dangerous pathology?

This pathological condition, which often complicates pregnancy and childbirth, is the most common cause of fetal mortality and morbidity in infancy.

Oxygen deficiency in different periods of pregnancy and childbirth is characterized by the development of various pathologies and various consequences. So, for example, during the period of laying organs, it is possible to slow down the development of the embryo and form developmental anomalies, during the period of tissue differentiation of organs - to a delay in further development, to pathology of development or to damage to the central nervous system (in 60-80%), to a violation of the adaptive mechanisms of the fetus and newborns, an increase in the incidence of the latter.

Severe intrauterine hypoxia of the fetus can also be the cause of stillbirth or death of newborns in the early postpartum period (in 23%), disorders or delays in newborns of intellectual and / and psychomotor development. In addition, they have lesions of the heart and blood vessels (in 78%), central nervous (in 98% or more) and urinary (in 70%) systems, and severe eye diseases.

What is fetal hypoxia?

The term "fetal hypoxia" is used to refer to a complex of changes in its body resulting from insufficient oxygen supply to its organs and tissues or inadequate absorption (utilization) of oxygen by them.

This is not an independent disease or a primary nosological form, but a condition that is the result of various pathological processes in the “mother-placenta-fetus” system and complicating the intrauterine development of the latter.

Even in the case of an uncomplicated, physiological pregnancy, the supply of oxygen to the fetus is significantly lower compared to adults. But compensatory-adaptive mechanisms (an increase in the heart rate, a large minute volume of blood, a significant oxygen capacity of the blood, etc.) at any stage of development ensure its resistance to this deficiency, bringing the oxygen supply to full compliance with the needs for it.

The disorder of compensatory mechanisms leads to a hypoxic state, which, depending on the duration, is divided into:

1. Chronic, developing as a result of oxygen deficiency for a long time with a complicated course of pregnancy. Chronic intrauterine fetal hypoxia is associated mainly with morphological and functional changes in the placenta, which occur, as a rule, as a result of a violation of its blood supply due to inflammatory, degenerative and other types of lesions.
2. Subacute, which is characterized by a decrease in the degree of adaptive ability of the fetus and develops 1-2 days before the onset of labor.
3. Acute, occurring already during childbirth. Acute fetal hypoxia very rarely develops during pregnancy. An unfavorable factor in terms of prognosis is its often observed development against the background of already existing chronic hypoxia.

Causes and forms of hypoxia

The idea of ​​numerous causes and mechanisms of development makes it possible to understand how to avoid fetal hypoxia during pregnancy. All causative factors are conditionally combined into three groups:

• diseases and disorders in the body of a pregnant woman, leading to oxygen deficiency - pathology in the cardiovascular and pulmonary systems, compression syndrome of the inferior vena cava, poisoning or intoxication of the body, anemia, blood loss or shock of various causes, complications during pregnancy or childbirth, accompanied by excess in the body of a woman carbon dioxide or oxygen deficiency;
• disturbances in the fetal-placental system that develop during post-term pregnancy, abnormal placental location or thrombosis of placental vessels, false node of the umbilical cord or thrombosis of the latter, fetal hypoxia during childbirth as a result of premature detachment of the normal located placenta, abnormalities of labor, entanglement of the umbilical cord, tension or prolapse last;
• pathology in the fetus - infection, the presence of congenital malformations, hemolytic disease, anemia, prolonged compression of the head during childbirth.

Forms of hypoxia in accordance with the mechanisms of its development

Arterial-hypoxemic

Which include:

• hypoxic, resulting from impaired oxygen supply to the uteroplacental circulation;
• transplacental - the result of circulatory disorders in the placenta or in the fetal-placental system and disorders of the gas exchange function of the placenta.

Hemic

Associated with anemia due to blood loss or hemolytic syndrome, as well as a decrease in the degree of affinity for oxygen of fetal hemoglobin.

Ischemic

Developing due to:

• low cardiac output with cardiac and vascular anomalies, insufficient contractility of the heart muscle or severe cardiac arrhythmias;
• increased resistance in the vessels (mechanical compression, thrombosis of the uterine arteries, etc.), including due to a violation of the properties of the blood.

mixed

Representing a combination of two or more mechanisms of oxygen deficiency.

In practice, arterial-hypoxemic and mixed forms are most common.

Oxygen deficiency is the main factor in the mechanism of development of metabolic disorders, the functioning of organs and, as a result, the development of a terminal state. A decrease in the degree of oxygen saturation of the blood leads to a violation of its respiratory function and the development of an acidic environment. Changed conditions are the cause of the violation of many parameters of constancy and self-regulation of the internal environment of the body.

Initially, the universal compensatory reaction is aimed at protecting vital systems and organs and preserving their function. This occurs by stimulating the hormonal function of the adrenal glands and increasing the release of catecholamines by them, as a result of which the fetal heart rate during hypoxia initially quickens. In addition, centralization of blood circulation (blood redistribution) develops due to vasospasm in certain organs that are not vital (lungs, intestines, spleen, kidneys, skin).

All this helps to improve blood circulation in vital organs (heart, brain, adrenal glands, placenta) and, accordingly, to increase oxygen delivery to them by reducing its delivery to "less important" organs and tissues, which leads to the development of metabolic acidosis (acid environment) in the latter.

Significant and prolonged hypoxia causes depletion of compensatory mechanisms, inhibition of the function of the adrenal cortex, a decrease in the content of catecholamines and cortisol in the blood. This causes a deterioration in endocrine regulation by the function of vital centers, a decrease in the frequency of heart contractions and a decrease in blood pressure, a slowdown in blood flow, stagnation of blood in the veins and its accumulation in the portal vein system.

Such disorders are accompanied by a change in blood viscosity and its flowing properties, microcirculation disorders, gas exchange disorders in them, a decrease in pH, an increase in the permeability of the walls of small vessels, swelling of tissues, etc.

Pronounced changes in macrodynamics and microdynamics, accompanied by metabolic disorders, cause tissue ischemia and even necrosis, primarily in the brain, as well as small, sometimes massive hemorrhages in it and in other organs, dysfunction of the respiratory and cardiovascular centers of the brain and etc.

Consequences of hypoxia in a child after birth

The severity and duration of these effects depend on the degree and duration of hypoxia. Depending on its intensity, there are:

• mild degree, or functional hypoxia - there are only hemodynamic disorders;
• deep, which is accompanied by a reversible violation of all types of metabolism;
• severe, or destructive, in which irreversible damage develops at the cellular level.

Clinical picture and diagnosis

Clinical signs and subjective symptoms of fetal hypoxia during pregnancy are very poor and difficult to recognize. This requires listening to the heartbeats by a gynecologist using a stethoscope.

As a result of auscultation of heartbeats, the assumption of the presence of a pathological condition may arise when there is a deviation from the norm (increase or, conversely, decrease) in the number of heartbeats. In these cases, it is necessary to conduct additional (instrumental-diagnostic) studies.

Is it possible to determine fetal hypoxia for a pregnant woman on her own?

A general idea of ​​the mechanisms of this condition helps a woman to understand that the lack of oxygen intake or utilization by the fetus necessarily leads to a change in the nature of its motor activity. You can recognize this with a correct assessment of your sensations during fetal movements.

How does the fetus behave during hypoxia?

At the initial stages of the pathological condition, a pregnant woman notes an increase in the frequency and intensity of movements. In the case of a long-term lack of oxygen or its progression, the degree of motor activity decreases up to the complete cessation of movement.

A decrease in the number of movements to 3 or less within one hour is a clear sign of hypoxic suffering and is a direct indication for the immediate conduct of additional studies to decide on the choice of further tactics for managing pregnancy.

Instrumental and diagnostic signs of fetal hypoxia in the later stages, sometimes even earlier, are detected through such indirect methods as echography, cardiotocography, blood flow in the vessels of the uterine-placental-fetal system, determination of the fetal biophysical profile, oxygen and carbon dioxide pressure, acid-base state and lactic acid content in the woman's blood, biochemical examination of amniotic fluid, the level of certain hormones, etc.

The most accurate and informative methods in late pregnancy (in the third trimester) are cardiotocography, ultrasound scanning and dopplerometry.

The initial signs of oxygen "starvation" during cardiotocography are:

• an increase in heart rate to 170 beats per minute or a decrease to 100 beats;
• a decrease in the degree of heart rate variability (rhythm variability), which is normally 5-25 beats per minute (indicates the normal regulation of heart function by the sympathetic and parasympathetic systems);
• short-term monotonous nature of the heart rate, constituting no more than 50% of the record;
• reduced response to functional tests;
• a cardiotocogram score of 5 to 7 points.

With a pronounced oxygen deficiency, the following are observed:

• significant (more than 170 beats per minute) tachycardia or bradycardia, less than 100 beats per minute;
• pronounced decrease in rhythm variability;
• the monotony of the heart rate, which is more than 50% of the record;
• a paradoxical response to functional tests and a late (after 10-30 seconds) reaction in the form of a decrease in the fetal heart rate in response to its movement (during a non-stress test);
• the cardiotocogram score is 4 points or less.

In the diagnosis of great importance is the Doppler study of blood circulation in the vessels of the brain and the fetal aorta. This technique at an earlier date, compared with cardiotocography, reveals intrauterine hypoxia in pregnant women and allows them to recommend constant careful monitoring and treatment.

Hypoxia during childbirth is also manifested by disorders of the heart. The most accessible diagnostic methods during this period are auscultation and cardiotocography.

Diagnostic symptoms in the first stage of labor include:

1. The initial signs (regardless of presentation) are bradycardia, which is about 100 beats per minute, an intermittent monotonous heart rhythm, a response to contractions, which is expressed in a late decrease in heart rate to 70 beats.
2. Pronounced signs are bradycardia, reaching 80 beats per minute with cephalic presentation or tachycardia (up to 200 beats) with breech presentation, persistent arrhythmia and monotony of the heart rhythm independent of presentation. In addition, responses to contractions, expressed in long-term late decreases in the frequency of the rhythm in the form of W-shaped complexes in the case of head presentation and a combination of its increase with a decrease (up to 80 beats per minute) - in breech presentation.

In the second stage of labor:

1. Initial signs - bradycardia up to 90 beats or an increase in the frequency of contractions (tachycardia) up to 200 beats per minute, intermittent monotonous heart rate, after attempts - a late decrease in heart rate to 60 beats per minute.
2. Pronounced signs are bradycardia up to 80 or tachycardia over 190 beats per minute, persistent monotonous rhythm, rhythm disturbance, late and prolonged slowing of the rhythm (up to 50 beats) with cephalic or pelvic presentation, with W-shaped complexes.

In addition, the presence of meconium in the amniotic fluid also speaks in favor of a threatening situation (but only with head presentation). It may be in the form of separate suspended fragments (with initial signs) or a dirty emulsion (in severe cases). However, its presence can be the result not only of acute hypoxia, but also of long-term or short-term oxygen deficiency that occurred before the onset of labor. Birth is possible without asphyxia if hypoxic episodes are not repeated.

An unfavorable sign during the first and second stages of labor, in contrast to the prenatal period, is the occurrence of a pronounced regular motor and/or respiratory activity of the fetus, which leads to severe aspiration syndrome.

Treatment and prevention of fetal hypoxia

The treatment program consists of correcting the therapy of concomitant pathology (if any), normalizing blood circulation in the placenta, improving the delivery of oxygen and energy components to the fetus, measures that increase its adaptive capabilities and the course of metabolic processes, as well as increase resistance to oxygen deficiency.

Direct treatment of fetal hypoxia is carried out using methods and drugs that contribute to:

1. Relaxation of the myometrium.
2. Expansion of the uteroplacental vessels.
3. Improving the rheological characteristics of blood.
4. Stimulation of metabolism in the myometrium and placenta.

For these purposes, bed rest is prescribed, a woman's breathing with a mixture of oxygen and air for 1 hour up to two times a day, taking a protein-oxygen cocktail, hyperbaric oxygenation - if the pregnant woman has cardiovascular insufficiency.

Of the drugs used are Sigetin, Efillin, Curantil, Trental, anticoagulants (Heparin), Methionine, folic acid, high doses of vitamin “B 12”, Cocarboxylase, Lipostabil, Haloscorbin, antioxidants (vitamins “E” and “C”, glutamic acid) .

In acute hypoxia, chronic hypoxia at a period of 28-32 weeks in the absence of the necessary result from the treatment, deterioration of the biophysical profile and cardiotocogram, the presence of oligohydramnios, the appearance of meconium in the amniotic fluid, emergency delivery is indicated regardless of the gestational age.

In the labor period, as a preparation for surgical () or obstetric (perineo- or episiotomy, the imposition of obstetric forceps, vacuum extraction, extraction by the pelvic end) the resolution of childbirth is used breathing with humidified oxygen, intravenous administration of glucose, Eufillin, Cocarboxylase and ascorbic acid, Sigetin.

Prevention consists in early prenatal diagnosis, treatment of concomitant diseases (cardiovascular and pulmonary pathology, diabetes mellitus, etc.), identification, thorough examination, as well as timely hospitalization and treatment of women at risk.
