术中人员流动对层流洁净手术室内空气及患者的影响研究

目的研究术中医务人员流动量对层流洁净手术室内空气含菌量、患者切口感染的影响。方法选择2018年3月至2019年6月于本院层流洁净手术室接受手术的患者143例,按医务人员流动情况分流动组108例和非流动组35例。对手术室空气采样并进行细菌培养,准确计算空气含菌量,观察患者术切口感染发生率,分析术中医务人员流动量与层流洁净手术室内空气含菌量及患者切口感染的相关性。结果流动组术中0.5小时、1小时、1.5小时、2小时及术毕时手术室空气含菌量均明显高于非流动组(p<0.05);1~10人次组术中0.5小时、1小时、1.5小时、2小时及术毕时手术室空气含菌量均明显低于10人次以上组(p<0.05);非流动组患者切口感染发生率0.00%(0/35)低于流动组的15.74%(17/108)(p<0.05);1~10人次组患者的切口感染发生率2.86%(1/34),低于10人次以上组的21.62%(16/74)(p<0.05);经Pearson相关性分析发现,术中医务人员流动量与层流洁净手术室内空气含菌量、患者切口感染发生率均呈正相关(r=0.629、0.738,p<0.05)。结论术中医务人员流动量与层流洁净手术室内空气含菌量及患者切口感染发生率存在显著相关性,即随着术中医务人员流动量增加,层流洁净手术室内空气含菌量增多,患者切口感染发生风险增加。
