Dressings and its sterilization

The material is used during operations and dressings for drainage of wounds and operating margins, tamponade RAS and application of a variety of bandages, called dressing. Dressings should have a good absorbency, quickly dry up, to be flexible, easily sterilized.
From many different dressings most widely gauze, cotton wool and lignin. Gauze-cotton fabric, possessing the ability to suck the blood, pus and other liquids. Gauze, elastic, soft, not contaminate the wound and so is the material from which prepare bandages, napkins, tampons, pads. Wool fiber seed pods of cotton. In medicine used absorbent cotton, which has great suction capability. Wool place the wound covered with a gauze, increasing intake capacity bandages and protection of wounds from external influences. Lignin - corrugated sheets thinnest paper, used instead of hygroscopic cotton wool.
The bandages are produced as non-sterile in large rolls and packs (preparation dressing material required size and sterilization have health workers on site)and sterile in a small hermetically sealed packages of parchment. For first aid outside the facility (in production, in the field, at home) the most convenient use of sterile packages. Sterile dressings produced in the form of bandages or napkins different sizes and widths and individual packages. Produce special bandages and packages, impregnated with antiseptics: iodoform, green diamond, syntomycin and other solutions that increase blood clotting, - hemostatic gauze.
First aid at the enterprises and in establishments providing medical workers of the health units or health post, those employees trained in first aid, have first aid kits, stretchers, tyres. Health centres and health posts should be provided with the necessary supply of sterile dressings. Most convenient for storage and use are ready standard packages with sterile bandages, napkins, cotton wool. Must have individual aid package, which allows you to quickly and securely protect the wound from pollution.
If there is no ready sterile material dressings you can prepare yourself out of pieces of non-sterile gauze (Fig. 1). Napkins, tampons put in packs of 10 pieces Packed in drums and autoclave. Sterile dressing material stored in sealed drums. In the absence of a standard individual packages make improvised individual packages. To do this, take a piece of gauze size 6X9 cm, in the middle of it almost to the edges of the stack equal layer of cotton wool, gauze folded over out and wrapped in parchment paper 16X16 see Individual packages are placed in Bix and sterilized.
Sterilization linen, dressing material most often is carried out with steam under pressure in autoclaves. Hence another name of this type of sterilization, autoclaving. The autoclave is a double-walled metal boiler (Fig. 2) with an airtight screw cap. Between the outer and the inner wall pour water up to the level indicated on the gauge glass. The inner part of the autoclave sterilization is the camera, which is placed sterilized items. Heating water in the autoclave is via electric heaters or stoves, gas burners. When boiling water evaporates, but as the output for the pair not, in the autoclave increase pressure and temperature. Under certain temperature and pressure microbes die. The pressure inside the autoclave is measured by a manometer. A red line indicates the maximum pressure that can be created in the autoclave. Adjust the pressure with the help of a safety valve.
