摘　　要：目的探讨层流洁净手术室对手术切口感染的影响,为不同类型手术的手术室安排及手术切口感染控制提供参考依据。方法采用回顾性方法对医院2010年1月-2011年6月普通手术室1652台手术以及2011年7月-2012年6月层流洁净手术室842台手术资料分析,比较各类切口在普通手术室和层流洁净手术室施行的手术切口感染率。结果洁净手术室手术切口总感染率为1.31%,普通手术室切口总感染率为2.66%,洁净手术室切口总感染率低于普通手术室(P<0.05);洁净层流手术室Ⅰ、Ⅱ、Ⅲ类手术切口感染率分别为0、0.40%、5.10%,普通手术室Ⅰ、Ⅱ、Ⅲ类手术切口感染率分别为1.14%、2.48%、5.77%,洁净层流手术室Ⅰ、Ⅱ类切口感染率低于普通手术室(P<0.05);Ⅲ类手术切口感染率同普通手术室差异无统计学意义。结论层流洁净手术室能够降低Ⅰ、Ⅱ类手术切口感染率,有利于医院感染控制。OBJECTIVE To investigate the effect of laminar flow clean operating room on the incidence of surgical incision infections so as to provide basis for the arrangement of operating room as well as for the control of surgical incision infections. METHODS Totally 1652 cases of operations in the ordinary operating rooms from Jan 2010 to Jun 2011 and 842 cases of operations in laminar flow clean operating rooms from Jul 2011 to Jun 2012 were enrolled in the study, then the clinical data of the cases were retrospectively analyzed, and the incidence of surgical incision infections was compared between the ordinary operating rooms and the laminar flow clean operating rooms. RESULTS The total incidence rate of surgical incision infections in the ordinary operating rooms was 2.66%, significantly higher than 1.31% in the laminar flow clean operating rooms （P〈0.05）. In the laminar flow clean operating rooms, the incidence rate of type I incision infection was 0%, the type Ⅲ incision infections 0. 40%, and the type Ⅲ incision infections 5.10% ; in the ordinary operating rooms, the incidence rate of the type I incision infection was 1.14%, the type Ⅱ incision infection 2.48%, and the type Ⅲ incision infection 5.77%, the incidence rate of the type Ⅰ incision infection or the type ; incision infection was significantly lower in the laminar flow clean operating rooms than in the ordinary operating rooms （P〈0.05） ; the difference in the inci- dence rate of type Ⅲ incision infection between the laminar flow clean operating rooms and the ordinary operating rooms was not statistically significant. CONCLUSION The laminar flow clean operating room may decrease the incidence rate of the type I incision infections or type Ⅱ incision infections, it is conducive to the control of noso- comial infections.
