Sterilization systems for intravenous fluids and blood transfusion and injection of intra-arterial blood begin with the preparation of rubber tubing. They are washed under running water to remove the talc and soak for 6-8 hours. in a solution of sodium bicarbonate (bicarbonate of soda) — 100 g of ammonia — 50 ml water — 10 liters. After repeated washing with running water they were boiled in distilled water for 30 min. and dried. Glass parts — control glass droppers — washed with hydrochloric acid or a 10% solution of potassium dichromate in sulfuric acid and repeatedly — running water. The system is mounted, or placed in a slut bags made of thick cloth and sterilized in an autoclave for 30-40 minutes at 2 am. Rubber tubing more than 3 times sterilize should not be, because they lose their elasticity and strength. As an exception, you can sterilize of boiling distilled water for 45 min.
Sterilization of anesthetic accessories — tracheal tubes (rubber and plastic), removable inflatable cuffs and masks — carry cold way. By boiling them go bad, lose their elasticity. Apply the solution diiodide (dvuyodistoy) mercury 1:1000 hydroalcoholic solution formaldehyde, water-alcohol solution chloramphenicol 1: 1000 or one of the solutions used to sterilize cutting tools. Solution poured into a tall wide cylinder, close the lid with holes on the tube diameter. They are placed in a cylinder vertically with the outside through the hole appeared segment length of 1.5-2 cm in the solution tube is kept at least 1 hour after a thorough mechanical cleaning of the mucus and pus. To do this, the tube is connected to a water tap and within 15-30 minutes. washed with a strong stream of water, and then wipe the inside and outside pad soaked in ether. The tubes can be sterilize in an autoclave for 30 minutes. at a pressure of 1,5 am. They are placed in a dressing box with walls draped with cheesecloth or a towel. The inner surface of masks and laryngoscope blades wash 0.5% solution of ammonia and repeatedly wipe cloth dampened with 96% alcohol. Metals — transitional tubes, forceps, dental braces — sterilized by boiling. Instruments for endoscopy sterilized without optics immersible oksitsianida mercury 1: 2000 1:5000 mercury or cyanide for 6 hours. Pre-wash them with warm soapy water and then wipe dry the alcohol. Optical part of the carefully wiped with alcohol and store in a dry gauze cap. Ureteral catheters and elastic bougies made of silk and special varnish impregnated, sterile couples formaldehyde in a glass or metal container, which is located at the bottom of the vessel with liquid formalin or formaldehyde pills. Metal bougies and catheters are sterilized by boiling.
Dental instruments are sterilized by boiling or in dry-air chamber at t ° 120 ° for 30-40 minutes.
