By sterile environment in operation theatres major part of such exogenous infections can be controlled. OT should be divided into four zones named protective, clean, aseptic and disposal zones. Proper ventilation, air circulation, temperature, maintenance of sterile environment in operation theatres plays key role in prevention of such infections. Steps for maintaining sterile environment include cleaning and disinfection of operation theatres by various means like chemical disinfection or disinfection with ultraviolet radiation. Along with this surgical instruments also can be a source of exogenous infections.
