The role of air ventilation and air sampling in reducing the incidence of surgical wound infection rates

Abstract

Air ventilation systems are a common feature in today's operating theatres. The main function is to decrease the bacterial load in the operating theatre, reducing the incidence of surgical wound infection rates. The ventilation system is only one of many factors which can contribute to a safe operating environment. Ever since the time of Lister the significance of airborne bacteria in the operating room has been a matter of interest and of dispute. The role of airborne bacteria acting as a source of infection for most types of operations continues to be a matter for debate. Despite the uncertainty, the development of laminar air flow and Plenum (conventional) ventilation systems has gained momentum, making it an essential standard of design and ventilation in the modern operating theatre.
