Abstract:
OBJECTIVE To learn about the factors affecting the quality of the air in operating-rooms and discuss the methods of improving their air quality.METHODS The dynamic and static air bacteriology between laminar air flow operating-room and normal operating-room of a fertiary care level hospital of grade Ⅰ in Changchun were observed.RESULTS The passing rate of samples for air static bacteriology between two types of operating rooms at the begining of selective operations(T0) was without difference.At the begining of emergency operations,there was a disparity.The total number of bacteria in normal operating-room increased with the operating-time,but in the laminar flow operating-room,the total number of bacteria increased in fluctuations during the(T2) time(60 ming since operation begain),and descended dramatically during the(T3) time(90 min since operation).CONCLUSIONS The emergency and operation-time are the main factors affecting the air quality in operating-room and the cleaning air-condition could improve the air quality.
