General information

Terms of use disinfectants

Perhaps, we should start with the fact that the algorithm for the preparation of disinfecting solutions is not as complicated as it seems at first glance. During the training of middle and junior medical personnel, disinfection is given special attention. Because it is these people who support the sanitary and epidemic regime in medical institutions.

Types of disinfection

Disinfectant working solutions are prepared immediately before cleaning. And the characteristics of the solutions, such as concentration and volume, depend on its type. There are four types of disinfection:

  1. Prophylactic. It is regularly held in medical institutions to prevent the development of infectious diseases in both patients and staff.
  2. Focal. Be sure to be carried out by employees of the sanitary-epidemic station in the source of infection of infectious diseases. This is necessary to stop the spread of infection and prevent massive infection.
  3. Current. Disinfection that “accompanies” the patient. That is, it is carried out wherever there is sick: at home, in an ambulance carriage, in an infectious diseases hospital, in a ward.
  4. The final. It is carried out in the focus of infection by specially trained personnel after the patient recovers or dies.

Disinfection methods

The number and concentration of disinfectant solutions are taken into account when choosing a disinfection method. The mechanical method involves the removal of microorganisms from the human body, tools and surfaces by washing, washing, damp cleaning or ventilation. This is the easiest way to disinfect, and it is often used to pre-clean medical instruments.

The chemical method is based on the use of various groups of agents that affect microorganisms. They can create a film on the surface of the tool, can kill bacteria or stop their growth. The choice of drug depends on the desired final effect. The treatment may be in the form of irrigation, wiping or falling asleep.

The biological method is based on the confrontation of different types of microorganisms. This allows you to achieve a monoculture of bacteria, which can then be destroyed in any other way. In modern disinfection, this method is no longer used because of its complexity.

The thermal method is one of the most common. This is known to all mothers boiling, pasteurization, as well as roasting with dry heat and autoclaving. Specialized rooms, the so-called TSO (sterilization treatment center), are equipped in medical institutions, where the disinfection of materials and instruments takes place.

Radiation or physical method involves the use of ultraviolet rays to neutralize microorganisms (quartz).

Classification of disinfectant solutions

The algorithm for the preparation of disinfectant solutions depends on the basic substance, which is used for the elimination of microorganisms.

There are the following groups of drugs:

  1. Halogen compounds: chlorine, iodine, bromine. As a rule, it is alcohol solutions that are diluted with water. They clean the skin well and sterilize surfaces in operating rooms and wards.
  2. Chlorine-containing drugs, such as calcium hypochloride, Javelion, or Chloramil C, go separately.
  3. For the mechanical cleansing of the wound and the wiping of instruments, oxygen-containing agents are used: hydrogen peroxide, virone, saidex. Getting to the areas of contamination, they provide a rich foam, which not only kills microbial agents, but also “pushes” them out of the damaged areas.
  4. Aldehyde containing agents - lysoformin and bianol.
  5. Surface active substances. The most frequent representatives are Samara and Minstral.
  6. Alcohols include preparations based on ethanol, propanol and isopropanol. They form a film on the surface of the skin that prevents bacteria from colonizing. The same principle of action and on medical instruments.

Precautionary measures

The algorithm for the preparation of disinfectant solutions includes all available precautions against the ingestion of drugs on the mucous membranes, in the respiratory tract or in the stomach. The rules primarily relate to the age of staff and health.

  1. Only persons who have reached the age of majority are allowed to work with disinfectant solutions. They are required to undergo a medical examination, as well as receive instructions on how to properly work with disinfectants, and sign in a safety journal.
  2. Pregnant women, as well as young mothers who breastfeed their babies, are excluded from such work. This is due to the fact that in small doses the drugs still enter the body of the personnel, and therefore can harm the child.
  3. All medical professionals should use goggles, respirators and protective gloves to reduce the harmful effects on the body and prevent chemical burns.
  4. Personnel must undergo a medical examination in order to identify the beginning of an occupational disease in time.

Preparation of the solution

The algorithm for the preparation of disinfectant solutions is quite simple. To clean the surfaces in medical institutions using solutions of bleach. The steps to dilute the powder are as follows:

  1. Wear a robe, mask, goggles and protective gloves.
  2. Kilogram dry bleach pour in a ten-liter bucket. Then slowly pour water (10 l) into this container, stirring gently.
  3. Close the bucket with a lid and leave it for 24 hours.
  4. Strain the solution, pour it into a bottle of dark glass, seal it tightly and write a label indicating the date and time of preparation of the solution.
  5. The shelf life of such a disinfectant is a week.

First aid for accidental poisoning disinfectants

In case of violation of the mode of operation, non-observance of precautionary measures and in emergency situations, personnel may experience symptoms of general poisoning or local irritation of the skin, mucous membranes of the eyes, and respiratory tract disinfectants.

First aid in case of contact with unprotected skin - immediately wash this area with clean water. If formaldehyde is affected, treat the skin with a 5% solution of ammonia.

If irritation of the respiratory tract occurs, immediately remove the injured person from the room to fresh air or to a well-ventilated room. It is necessary to rinse the mouth and nasopharynx with water. In case of poisoning with formaldehyde, inhalation of water vapor with the addition of a few drops of ammonia is recommended, taking warm milk with sodium bicarbonate (baking soda) or Borjomi. According to the testimony - heart, sedative, antitussive, inhalation of oxygen. In severe cases, hospitalization.

If any drug gets into the eyes, they are immediately washed with a stream of water for several minutes. When eye irritation is instilled solution of albucide, with pain - 1-2% solution of novocaine.

In case of accidental ingestion of the chloro-active preparations in the stomach, it is washed with 2% sodium thiosulfate (hyposulfite) solution and 5-10-15 drops of ammonia with water, milk, baking soda, magnesia suspension (one or two tablespoons per glass of water) are given inside. In case of poisoning with formaldehyde, the stomach is washed with the addition of ammonia or 3% sodium carbonate (ammonium) solution to water. After washing, give raw eggs, protein water, milk.

Do I need to store and fit something in every pocket?

An iodine pen is a glass ampoule protected by a plastic case less than ten centimeters. So it is not a problem to take it with you. As the name suggests, it contains iodine, and therefore its use is the same as spray and ointment containing iodine.

Your choice: hand sanitizer gel. Disinfectant gels are made in the form of larger bottles with bottles or in small bottles of 50 ml or less. If necessary, they will also check at the airport. A small amount of the drug is applied to the hands, tilted and allow to dry freely. These products destroy the most common bacteria, fungi and viruses. However, skin may dry slightly.

Contraindications:Allergic reaction to chlorine-containing drugs

Safety nurses in the workplace:

2. Medical first aid kit.

Remember! Persons not younger than 18 years old are allowed to work with chlorine-containing drugs.

1. A hinge of dry powder chloramine 10 g

Do I need to disinfect large areas of skin?

Your choice: hypermanganes, iodine solutions. Hypermangan is available in the pharmacy as a deliberate powder. Used for disinfection baths. If you are preparing the solution of hypermans at home, it is important to dissolve only a few granules of the super-manganese powder. The resulting solution should be slightly pink. If you exceed the concentration of hypermanganate in the solution, it can cause skin burns.

The correct concentration depends on how it is used. As a rule, solutions are 1%, 5% or 10%. More concentrated iodine solutions are used in a hospital environment. Your choice: drops or ointment with septonex, a solution of boric acid and benzodedetsinom.

2. Capacity for water with marking to 1 l.

3. Capacity for des. solution.

4. Wooden spatula.

The sequence of actions m / s to ensure the safety of the environment:

1. Put on the second (surgical) gown, rubber apron, respirator or eight-layer mask, goggles, shoe covers, rubber gloves.

2. Check the operation of the supply and exhaust ventilation and alarm, turn on the ventilation.

Drops containing septonex can be applied one drop up to 5 times per day on the affected eye. After opening, the drops must be consumed within a month. If the symptoms of inflammation do not disappear within a few days, it is recommended not to continue with your doctor and consult a doctor. The fabric can be applied three times a day, but you can see it blurred for a while. The first centimeter of ointment is extruded and discarded before first use.

In addition to the solution, the solution is filled with a solution, the solution is applied to the eye, and eye movements are performed by the eye from 2 to 5 minutes, up to 5 times a day. Your choice: tea tree oil, sage. Tea tree oil is mainly used in traditional Oriental medicine for disinfection and treatment of various inflammatory conditions due to its antibacterial properties. Apply a few drops directly to the affected site.

3. Check for yourself (call the laboratory technician) chlorine activity and proper storage.

4. Hang a stencil on the door from the outside - “Do not enter! There is a preparation of des. solutions! ”, indicate the time when preparation is started.

5. Conveniently position the equipment you need, check the marking.

6. Pour a small amount of water into the container (preferably warm - to better dissolve the powder).

Sage is ideal for disinfecting the oral cavity. It is available in the pharmacy as saliva or alcohol tincture. You can make your infusion from home only by pouring hot water. Alcohol tincture must be diluted - half a teaspoon in 150 ml of warm water before use. Sage and drugs should not be used by pregnant and lactating women.

Your choice: disinfecting alcohol, disinfecting iodine. Even before removing the tick, it is recommended to abandon it by disinfecting alcohol, and then remove it with special ticks to remove ticks. Liquid disinfection is a multifunctional 60% alcohol used, for example, to disinfect newborn puppies. Before injection, it is also suitable for alcohol-impregnated dishwashers for single use.

7. Place a portion of dry chloramine powder (10g) in a container with water.

8. Add water to the 1l mark.

9. Stir the solution with a wooden spatula.

10. Close container tightly.

11. Attach a tag to the container - marking with the date, time of preparation and the name of the person who prepared it, his position.

12. Remove protective clothing.

13. Wash your hands, face with soap, dry off, rub into the skin of your hands silicone cream (any softening cream).

14. Close the lock room.

Evaluation of the results achieved

METODDYDESINS

Most often used in health care facilities:

  1. Mechanical method: wet cleaning, washing, washing hands, whitewashing and painting the premises.
  2. Physical method: ultraviolet irradiation, boiling, ultrasound, steam method.
  3. Chemical method: all methods are applied - rubbing, full immersion (soaking), irrigation, spraying, falling asleep.
  4. Combined method: washing hands with antiseptic soap, wet cleaning with disinfectants + UV.
  1. Question: Preparation of disinfectant solutions.

For the preparation of disinfectant solutions personnel is provided with disinfectants approved for use in the Russian Federation. When preparing disinfectant solutions, observe safety precautions when working with disinfectants in accordance with the instructions (guidelines) for the preparation. Solutions of disinfectants are prepared according to the instructions for use of the drug (guidelines) (see manipulation number 6). Tanks for the preparation of disinfectant solutions should be glass, enameled (without damage to the enamel), plastic. Tanks must be fitted with tightly fitting lids and labeled:

The expiration date

For disinfectants produced in the form of solutions of concentrates and in the form of powder, use appropriately sized measuring containers. For the preparation of disinfectant solutions using tap water. Some disinfectants require the preparation of a stock solution first, and then working solutions are prepared from it (for example, bleach) (see manipulation number 7).

Indicators are used for express control of working solution concentrations. The indicator should correspond to the tested solution. Firm "VINAR" produces indicator strips of the series "Dezikont". "Dezikont-NA" is used to control the neutral anolyte, "Dezikont-S" is used to control the "Septodor", etc.

  1. Question: The use of disinfectant solutions.

Disinfecting solutions are used to disinfect medical products, medical instruments, furnishings, premises, sanitary equipment, cleaning equipment, dishes, linens and care products.

Disinfection by wiping is carried out on objects that are not in contact with the patient or to which the immersion method cannot be applied. Wipe once or twice (according to the instructions) with a cloth moistened with disinfectant solution or a cloth soaked in disinfectants.

Dip disinfection is carried out:

  1. Option: the product is immediately immersed in a disinfecting solution.
  2. Option: visible impurities are removed from the product with the help of cloth napkins, then the product is immersed in disinfecting solution (the napkins are dumped into a separate container).
  3. Option: the product is pre-washed in a container with water (with a disinfecting solution), and then immersed in a disinfecting solution, the washings are also disinfected.

When disinfecting by immersion, detachable products are immersed disassembled. Tools with locking parts are immersed open, making several working movements in solution. Instruments having cavities and channels are immersed with the filling of their cavities. The height of the disinfecting solution above the tools is at least 1 cm.

Irrigation disinfection is carried out using disinfectants in the form of sprays or solutions are applied to the surface using special equipment.

After disinfection, items of care, medical devices and reusable instruments should be washed from the remains of the disinfectant in accordance with the recommendations of the manufacturer of the disinfectant.

Solutions of disinfectants are used for cleaning the wards and treatment room (see manipulation number 8, 9). There are washing-disinfectants of the new generation that do not require rinsing. Solutions of some disinfectants can be combined with a 0.5% detergent solution (Chlormix, Javel-Solid) according to the instructions. If the instructions do not indicate that solutions can be combined with detergent, then this cannot be done, as this may lead to a decrease in the activity of the disinfectant.

Calculation of disinfectant solution consumption is carried out according to the instructions for use.
