两种手术室空气质量的对比分析

目的 了解影响手术室空气质量的相关因素,探讨提高手术室洁净度的措施.方法 对长春市某三甲医院的普通手术间和层流手术间进行空气静态和动态细菌学监测.结果 普通手术间和层流手术间静态采样合格率分别为98.97%、99.02%,两组比较差异无统计学意义;普通手术间和层流手术间在择期手术开始时(T_0)采样合格率分别为93.51%、94.67%,两组比较差异无统计学意义(P>0.05);普通手术室和层流手术室在急诊手术开始时(T_0)采样合格率分别为78.95%、93.88%,两组比较差异有统计学意义(P<0.05);普通手术室随着手术时间的延长细菌总数逐渐增加,层流手术室在手术开始的T_2内,细菌总数呈波动性上升,T_3后显著下降.结论 急诊手术、手术时间是影响手术室空气质量的危险因素.手术室采用净化空调系统可以提高空气洁净度.

Air Quality Between Two Types of Operating-rooms:A Comparative Analysis

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 (T_0) 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 (T_2) time (60 ming since operation begain), and descended dramatically during the (T_3) 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.
