The bactericidal lamp is equipped at a height of no more than two meters. A strict record of the operating time of bactericidal lamps is maintained. In the offices there should be a quartzing and ventilation schedule. Weekly (during the general cleaning) the lamp is treated from all sides with a disinfectant solution, and then washed off with water. Means, active substances used for the conduct of disinfection.
Routine cleaning can be carried out as preventive disinfection using a wet method.
Disinfection – a set of methods for the complete, partial or selective destruction of vegetative pathogenic microorganisms for humans on environmental objects and on medical products. It is one of the most significant areas of prevention of nosocomial infections.
All hospital strains of nosocomial pathogens, along with almost complete antibiotic resistance, have significant resistance to external factors, incl. disinfectants.
Distinguish between current and general cleaning. Current cleaning is carried out in a wet way.
Paragraph 103 of the sanitary rules: wet cleaning of premises with washing floors, wiping furniture, equipment, window sills, doors, handles should be carried out constantly, but at least 2 times a day, using detergents (in surgical, obstetric departments at least 3 x times a day, including 1 time using disinfectants).
Routine cleaning in wards for patients, corridors, common areas in somatic hospitals should be carried out with working solutions of disinfectants according to the bactericidal regimen.
In ward departments of a therapeutic profile, disinfectants are used after a change of linen, as well as according to epidemiological indications.
Routine cleaning by the type of preventive disinfection is carried out 2 times a day in all rooms where parenteral interventions are performed, work is carried out with infectious patients or biological material from patients (operating rooms, dressing rooms, maternity rooms, intensive care units, neonatal wards, treatment rooms, infectious departments, dairy rooms, bacteriological, virological laboratories, admission department, CSO), followed by the use of disinfectants with exposure to the virucidal regimen.
Buffet departments are cleaned using disinfectants after each distribution of food, i.e. 3 times a day. Item 237.
The sequence of the current disinfection;
• Put on overalls for cleaning (robe, hat, apron, gloves, slippers).
• Prepare a 2% soap-soda solution (100.0 soap, 100.0 soda) or Sandim ShchP. Apply detergent to all treated surfaces. Wash it off with water.
• Apply disinfectant working solution.
• Wash off with clean water.
• Disinfect cleaning equipment: soak a rag, rags in disinfectant. solution in separate containers, rinse, dry.
• Remove the used spec. clothes.
• Carry out hygienic hand antisepsis.
• Put on clean overalls.
• Turn on the quartz for 30 minutes, ventilate for 15 minutes.
General cleaning is carried out in accordance with the schedule drawn up by the elder sister once every 7 days in sensitive departments and once a month in other functional rooms.
Disinfection levels: high, medium, low.
3.4. Disinfection modes: bactericidal, virucidal, fungicidal, tuberculocytic.
Types of disinfection: preventive , current, final For disinfection, the following methods are used: mechanical, physical, chemical, combined. All disinfectants can be divided into 9 main groups of chemical compounds:
1. Galloid compounds
5. Aldehyde-containing substances
7. Phenol-containing products
In accordance with the 165th order, each UZ must calculate the need for disinfectants, and provide an irreducible monthly supply of disinfectants. funds, as well as a change of misinformation. funds once a quarter.
3.5. Disinfection methods for medical instruments:
Pre-sterilization cleaning (PSO) – is carried out in order to remove protein, fat, mechanical contaminants, drug residues. Reusable products subject to sterilization are exposed. For PSO, solutions containing hydrogen peroxide and detergents (Lotus, aster, progress) are used.
If the agent has detergent properties along with antimicrobial properties, PSO can be combined with disinfection, which makes it possible to simplify the processing of the instrument.
Solutions of preparations for PSO may be used repeatedly until visible signs of contamination appear, but no more than for the time specified in the methodological document for the use of a particular agent.
PSO stages – soaking in a washing solution, washing each product in the same solution with a ruff, cotton-gauze swab, napkins, rinsing with drinking running water, rinsing with distilled water. After the PSS, the product is dried until the complete disappearance of moisture at a temperature of 85 degrees in dry-air cabinets. JI quality control
Control is subject to 1% of each product name, but not less than 3 units. The quality of PSO is assessed by setting an azopyram test for the presence of residual amounts of blood, oxidizing agents, washing powder with a bleaching effect, chloramine, rust, acids.
Disinfection, sterilization of medical devices in accordance with the requirements of the order of the Minsk Health Committee No. 165 dated November 25, 2002 “On disinfection and sterilization in UZ”.
All medical instruments, utensils, underwear, devices contaminated with blood or other biological fluids that come into contact with mucous membranes immediately after use are subject to disinfection in accordance with the order of the Ministry of Health of the Republic of Belarus No. 66 dated 2.04. 1993 “On measures to reduce the incidence of viral hepatitis in the Republic of Belarus”. This is primarily aimed at preventing occupational infection of medical personnel.
After disinfection, the products are washed with tap water, dried and used for their intended purpose, or subjected to pre-sterilization cleaning and sterilization.
4. In order to prevent nosocomial infections in ultrasound, regardless of the profile, three important requirements must be met:
• minimizing the possibility of introducing infection;
• exclusion of nosocomial infections;
• exclusion of the removal of the infection outside the medical institution.
In matters of prevention of nosocomial infections in hospitals, middle and junior medical staff are given the main, leading role of the organizer, responsible executor, and also the controller. Daily, careful and strict compliance with the requirements of the sanitary-hygienic and anti-epidemic regime in the course of performing their professional duties forms the basis of the list of measures for the prevention of nosocomial infections.
An important role in preventing the occurrence of nosocomial infections is played by measures aimed at reducing the microbial contamination of surfaces and air with the help of bactericidal irradiators, which are equipped at a height of no more than 2 meters. It is necessary to keep a strict record of the operating time of germicidal lamps. Depending on the type, the lamp is designed for 5000 or 3000 hours. In the offices there should be a quartzing and ventilation schedule. Every week (during general cleaning) the lamp is wiped from all sides from dust and grease deposits with a dry gauze cloth. The armature of the bactericidal lamp is treated with a disinfectant solution, and then washed off with water.
