两种空气净化机对手术室空气动静态消毒菌落数对比研究

目的比较2种不同消毒机对Ⅱ类手术室空气消毒的效果。方法将两个空间相等、条件基本相同的手术室随机分为观察1组和观察2组,观察1组用新型空气消毒机净之界,观察2组用动态消毒机,分别于消毒1h后于手术前0min,手术开始后20、40、60min做标准5点采样,比较二者的消毒效果。结果两种动态空气净化系统在术前0min,杀菌效果差异无统计学意义（P〉0.05）,在手术开始20、40、60min 3个时间段两组差异有统计学意义（P〈0.01）。结论新型空气消毒机净之界优于动态消毒机消毒效果,同时安全、经济,不产生衍生、次生污染物,值得临床推广使用。

Effect comparison between two kinds of air purification machine of dynamic and static air disinfection for the operating room

Objective To compare disinfection effects between two different kinds of disinfection instruments for the classⅡ operation room air.Methods the same basic conditions of operating rooms were randomly divided into observation group 1and observation group 2.In group 1,we used the new air disinfection,and in group 2,we used dynamic disinfection machine disinfect operating rooms.Take standard 5-point sampling after disinfection for 1h,operation for 0,20,40,60min,respectively,then compare the effect of the two disinfection ways.Results At the preoperative 0min moment,the two dynamic air purification system′s disinfection effects had no statistically significant（P＆gt;0.05）.But at the preoperative 20,40,60min moment,the disinfection effects between the two groups was statistically significant（P＆lt;0.01）.Conclusion The disinfection effect of the novel air disinfection machine is superior to the dynamic disinfection machine.Simultaneously,there was security,economic,no derivative,no secondary pollutants by novel air disinfection machine.It is worth of the clinical use.
