不同消毒方法对手术室空气消毒的效果比较

目的：探讨不同消毒方法对手术室空气消毒的效果。方法：自2007年1月至2008年1月间分别采用空气洁净器法、过氧乙酸喷雾法以及紫外线灯照射法对3间手术室进行消毒并监测空气消毒效果。结果：空气消毒器法自然菌消除率为94.59%,过氧乙酸喷雾法为89.32%,紫外线灯照射法为81.83%。消毒30min后,空气消毒器法细菌总数明显低于过氧乙酸喷雾法和紫外线灯照射法,自然菌消除率明显高于紫外线灯照射法,差异均具有统计学意义（P〈0.05）。过氧乙酸喷雾法细菌总数明显低于紫外线灯照射法,两者比较差异具有统计学意义（P〈0.05）。结论：三种方法均是有效的手术室空气消毒方法,其中空气洁净器使用范围更广泛,使用更方便。

Comparison of Air Sterilization Effect in Operating Room about Different Disinfection Measures

Objective:To investigate the effect of air sterilization in operating rooms about different disinfection measures.Method: 3 operating rooms were disinfected by aerpurity appliance,peracetic acid nebulization and ultra-violet lamp irradiation from January in 2007 to January in 2008 respectively,and the effects of air sterilization were detected.Result: The elimination coefficient of physio-bacterium was 94.59% in aer-purity appliance,89.32% in peracetic acid nebulization and 81.83% in ultra-violet lamp irrad...
