摘　　要：目的：探讨层流系统对手术室空气净化的效果和安全性，减少手术感染的机率。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组和对照组，观察组采用层流系统进行空气净化，对照组用动态消毒机，分别于消毒前10min和消毒后30min，手术开始后30min、60min、90min、120 min和150min做标准5点采样，比较二者的消毒效果。结果：观察组在术前30min、术后150min尚能达到普通洁净手术室空气含菌量≤200cfu/m3的标准；对照组术后90min已经超过普通洁净手术室空气含菌量≤200cfu/m3的标准，菌落总数量持续增加。两组消毒效果差异具有统计学意义（P＜0.01）。结论：层流系统进行空气净化消毒效果优于动态消毒机，同时使用简便、快速、安全，值得临床推广使用。Objective： To explore the air disinfection effect and safety of operation rooms were decontaminated by laminar system, and reduce the risk of surgical infection. Methods： Two operation rooms with same volume and almost same conditions were divided randomly into observation group and control group, the observation group receiving air disinfection with laminar system, the control group receiving disinfection dynamic sterilizer, the samples were respectively taken 30 minutes before the operation and 30 minutes, 60 minutes、90 minutes、120 minutes and 150minutes after the beginning of the operation, the air disinfection effect was observed and compared in two groups. Results： The common standard of bacterium content ≤200 cfu/m3 was respectively reached in 30 min before operation and 150 minutes after the beginning of operation in observation group,but the standard of bacterium content ≤200 cfu/m3 can not be reached beyond 90 minutes,the amount of total colony continuously increased in control group. There was a significant difference between the two group （P〈0.01）. Conclusion： Disinfection effect of laminar system is better than the dynamic sterilizer, and convenient, quick, safe, hence is worthy of being recommended in clinical practice.
