1、导尿管相关尿路感染的易发因素及预防的研究作者：苏燕娟，陈佩燕，佘衍玲，陈燕君【摘要】目的：研究导尿管相关的尿路感染的易发因素，提出预防措施。方法：对108例患者在导尿前均行尿培养证实无尿路感染。108例随机分为A和B两组。A组包括A1组和A2组，A1组(24例)更换引流袋1次/d，A2组(30例)更换引流袋1次/3d。B组包括B1组和B2组。B1组(23例)接受膀胱冲洗2次/d。B2组(31例)不行膀胱冲洗。全部病例均于导尿后第4天和第7天进行尿液细菌培养。结果：更换引流袋的时间和患者的菌尿明显相关，每3d更换引流袋的

2、菌尿发生率低于每天更换者(χ2=6.89，P<0.01);膀胱冲洗组菌尿的发生率高于不冲洗组，差异有显著性(χ2=4.58,P<0.05);留置尿管的时间越久，菌尿的发生率越高(χ2=7.99，P<0.01)。结论：导尿后不膀胱冲洗，引流袋更换2次/周，缩短尿管留置时间等能降低尿路感染率。【关键词】导尿管；尿路感染；膀胱冲洗；引流袋　　AStudyoftheLiableEpisodeAgentoftheUrinaryTractInfectionwithAssociationofCatheterandi
