Theme: Organization of work in sterilization one. Preparation and sterilization of cutting, optical, generalsurgical instruments. Sterilization of stitch material.

І. Actuality of theme

Among complications in surgery most often there are complications of infectious character. They can result in a fatal outcome, in spite of the brilliantly executed operative interference. Warning of such complications is main principle of surgery, in the basis of which an asepsis and antiseptic lie. For warning of contact infection of wound it is necessary to attain sterility of all that will get in with a wound. It is achieved by sterilization of operating linen, bandaging and stitch material, gloves, instruments, by treatment of hands of surgeon and operating field. Sterilization of stitch material, surgical tool is directed on a prophylaxis both contact, and implantation infection of wound.

ІІ. Purpose of employment:

1. To learn structure and organization of work in sterilization one.

2. To know classification of surgical tool

3. To be able to prepare surgical instruments of sterilisation.

4. To be able to conduct tests on quality of before sterilisation treatment of surgical instruments.

5. To be able sterilisation cutting, optical, generalsurgical instruments.

6. To know classification of stitch material and requirement of it.

7. To be able to conduct sterilization of stitch material.
