Presterilization cleansing of ALV apparatuses and anesthesia equipment
Both new and long in use apparatuses are subject to cleansing. To wash elements and component parts of devices, a mixture of 3% hydrogen peroxide and 0.5% detergent solution is applied. This allows to combine cleansing and disinfection into one process. The activity of detergents increases at 50°C. The apparatus is disassembled up to its units, flushed out under a jet of cold water, then with warm water in terms as short as possible following the use of apparatus (patients discharges may dry out). It is steeped by a complete submersion into a hot (50°C) detergent solution for 15-20 min with all spaces being filled. Then it is washed with a cotton and gauze tampons in the same solution — for 25-30 sec per each item. Tampons are used only once, solutions are changed in proportion to their contamination (by colour). Rinsing — for 5 min in transparent water (if a powder "Astra" or "Lotos" was used as a detergent solution — then 10 min), a phenolphthalein test is carried out, whereupon it is rinsed in distilled water, dried out with sterile bed sheet and decontaminated. In case of tuberculosis, gas gangrene or tetanus 3 ml of hot water (for humidifying) are introduced into the closed circuit of the apparatus for 30 min, then formaldehyde — for 4 hrs. Rubber items: masks, endotracheal tubes, air ducts, mouth-pieces, nozzles are immersed in 3% hydrogen peroxide for 60 min., 3% formaldehyde — 30 min., 1% chloramine — 30 min., 0.1% deoxone — for 20 min. Items for tracheostomy, made of metal, are boiled in distilled water for 30 min. After decontamination it is flushed with sterile water, dried and stored under aseptic conditions. Connective elements, made of metal or heat resistant plastics, are boiled or placed in the solution as for rubber items. Respiratory hoses, humidifier body and hot-wells are flushed immediately after use under a jet of running water, then washed according to the following regimen: 3% hydrogen peroxide + 0.5% detergent solution at 50°C. Then, they are decontaminated in hydrogen peroxide, chloramine or formaldehyde, flushed twice in distilled water, dried (hoses in suspended condition). An "accordion-like" respiratory bag is filled with detergent solution, flushed and decontaminated as hoses (flushed with distilled water and dried in suspended condition). Nonremovable valve boxes are drained, flushed with detergent solution, rinsed and wiped out with 70° alcohol. Removable parts of the valve are boiled. In case of tuberculosis decontamination of component parts and units, made of rubber and plastic, is carried out by the immersion into 3% hydrogen peroxide for 3 hours, 10% formaldehyde — for 1 hour, 5% chloramine — for 2 hours, 1% deoxone — for 30 min. Units, made of metal, are boiled for 30 min. In tetanus and gas gangrene: 6% hydrogen peroxide — for 6 hours, 1% deoxone — for 45 min, 10% formaldehyde — for 4 hours.
