INFECTIOUS SAFETY AND
INFECTION CONTROL
Infection control is a system of effective preventive and anti-epidemic measures aimed at preventing the occurrence and spread of nosocomial infections, based on the results of epidemic diagnosis.
The goal of infection control is to reduce the morbidity, mortality, and economic impact of nosocomial infections. A nosocomial infection is any clinically recognizable infectious disease that manifests itself in a hospital setting or when seeking treatment, an infectious disease of a hospital employee resulting from his professional activities, regardless of the onset of symptoms of the disease before or during the stay in the hospital. Requirements for the implementation of sanitary-anti-epidemic and sterilization-disinfection regimes are regulated by orders of the Ministry of Health of the USSR No. 288/76, No. 720/78, Ministry of Health of the Russian Federation No. 170/94, OST 42 21-2-85 and guidelines for disinfection, pre-sterilization cleaning and sterilization of products for medical purposes MU-287-Sh of December 30, 1998 and SanPiN 2.1.3.2630-10 "Sanitary and epidemiological requirements for organizations engaged in medical activities" (approved by the Decree of the Chief State Sanitary Doctor of the Russian Federation of May 8, 2010 No. 58)
Basic requirements for the work of a procedural nurse
In order to prevent infection of patients, it is necessary to carry out all types of injections, strictly observing the rules of asepsis and antisepsis. An individual disposable sterile syringe and needle is used for each patient. All manipulations are carried out by the procedural nurse in sterile gloves.
Used syringes, gloves, before disposal, are disinfected according to one of the permitted regimes in accordance with the order of the Ministry of Health of the Russian Federation No. 408 / 89 and SanPiN 2.1.7.2790-10 "Sanitary and epidemiological requirements for the treatment of medical waste."
Class A waste is collected in disposable bags or reusable containers. The collection rules for this class of waste are similar to the requirements for ordinary municipal solid waste.
Classes "B" and "C" must be collected in a disposable package. Transporting them outside the medical department in the open is prohibited.
Disposable bags with waste of classes "A", "B", "C" are subject to mandatory labeling with the code of the health facility unit, the date and name of the person responsible for collecting the waste.
Disinfection, PSO, general provisions
Disinfection, pre-sterilization cleaning and sterilization of medical devices (hereinafter referred to as products) are aimed at preventing nosocomial infections in patients and staff of medical institutions.
Disinfection of products is carried out in order to destroy pathogenic and opportunistic microorganisms-viruses (including pathogens of parenteral hepatitis viruses, HIV infection), bacteria (including Mycobacterium tuberculosis), fungi (including fungi of the genus Candida) - on medical products, in their channels and cavities.
All products are subject to disinfection after their use by the patient. After disinfection, disposable products are recycled.
Containers with solutions of disinfectants must be equipped with lids, have an inscription indicating the name of the agent, its concentration, purpose, date of preparation (for ready-to-use agents approved for repeated use, indicate the date when the agent was used).
Types of disinfection: physical, chemical.
Pre-sterilization cleaning
. Pre-sterilization cleaning of medical devices is carried out after their disinfection and subsequent washing of the remains of disinfectants with running drinking water.
. Pre-sterilization cleaning is carried out manually or mechanized (using special equipment) method.
. If the product, along with detergents, also has antimicrobial properties, pre-sterilization cleaning of products at the stage of soaking or boiling in a solution can be combined with their disinfection. . Detachable products are subjected to pre-sterilization cleaning in disassembled form.
When soaking or boiling in a washing solution, the products are completely immersed in the detergent solution, filling the channels and cavities of the products with it.
Washing is carried out with the help of a ruff, cotton-gauze swabs, cloth napkins; product channels are washed with a syringe. The use of a ruff when cleaning rubber products is not allowed.
Sterilization
Sterilization of medical devices is carried out in order to kill all pathogenic and non-pathogenic microorganisms on them, including their spore forms.
. Sterilization is carried out by physical (steam, air) and chemical (use of chemical solutions, gas) methods. The choice of an adequate sterilization method depends on the characteristics of the items to be sterilized.
. When sterilizing with steam, air and gas methods, products are usually sterilized packed in sterilization packaging materials; in the steam method, in addition, sterilization boxes without filters and with filters are used.
Disinfection of premises, furnishings
- repeated wiping with a rag soaked in a disinfectant solution with an interval of 15 minutes.
Rags processing.
. Immersion in one of the disinfectant solutions for 60 minutes. followed by rinsing, drying and sterilization before use.
. Boiling in a 2% soda solution - 15 minutes.
. Boiling in distilled water - 30 min.

The quality of pre-sterilization cleaning (PSO) is checked by setting azopyram or amidopyrine samples for the presence of residual amounts of blood and by setting a phenolphthalein sample for the presence of residual amounts of alkaline components of detergents. PSO quality control is carried out by TsGSEN - quarterly.
Self-control in health care facilities is carried out:
- in the central sterilization departments (CSO) - daily;
- in departments - at least once a week (organized and controlled by the head nurse).
. Subject to control: in the CSO -1% of each item processed per shift,
. In the case of a positive test for blood or residual amounts of alkaline components of detergents, the entire batch of controlled products from which they were selected for control is subjected to repeated cleaning until negative results are obtained. The results of the control are noted in the quality log of the PSO medical device in the form No. 366 / y.
