Aseptic Technology

Aseptic technique is a general term involving practices that minimize the introduction of microorganisms to patients during patient care. There are two categories of asepsis; general asepsis which applies to patient care procedures outside the operating theatre and surgical asepsis relating to procedures/processes designed to prevent surgical site infection. 
Aseptic technique includes preparation of the patient, such as hair removal and disinfection of the operative site; preparation of the surgeon, such as provision of decontaminated surgical attire, surgical scrub, and sterile surgical gloves; sterilization of instruments supplies, and implanted materials; and the use of operative techniques to reduce the likelihood of infection.
