会阴侧切伤口医院感染的相关危险因素分析

目的为调查2009年8—10月深圳某医院妇产科产妇会阴侧切伤口发生医院感染事件的原因和预防相关院内感染的发生。方法采用描述性分析和病例对照的方法,了解某医院产科医院感染发生情况并对医院感染发生相关因素进行探讨。结果272例侧切术病人中8例发生医院感染,术后感染率为2．94％。经调查,会阴侧切缝合术后住院天数≥3d（x2=0．01,P=0．01）、住院时有合并症（Fisher＇sExectTest,P=0．04）是产科会阴侧切术产妇医院感染发生的危险因素,而产房物品表面（〉5cfu／m2）及病房空气（〉200cfu／m2）细菌污染严重可能为该次医院感染发生的直接原因。结论提高手术质量,做好产后护理及产房与病房的消毒工作是预防产妇会阴侧切伤口发生医院感染的重要措施。
