[Analysis of influential factors of suspended bacteria in air in operating rooms].

In order to control the air borne bacterial contamination of operation in operating rooms, we designed to do air sampling with FA-1 suspending air bacterial particle sampling kits. Samples were from purified operating rooms and nonpurified operating rooms, aseptic operation and contaminated operation. Data were collected in 7 different stages and 3 different altitudes. Data were statistically analysed by means of logistic linear model. The results help us understand the influencing factors of air contamination. Strategies of control of those factors were discussed.
