泌尿外科医院感染危险因素分析

目的：探讨泌尿外科医院感染的危险因素。方法：回顾性调查1996年4月－1999年4月间我院泌尿外科手术患者2976例的医院感染情况。结果：泌尿外科医院感染率为4．87％，其中男性占73．1％，女性占26．9％；感染部位依次为下呼吸道、手术伤口、泌尿道、胃肠道、上呼吸道、皮肤软组织；I类切口术后感染率为4．4％，Ⅱ类切口术后感染率为30．3％，Ⅲ类切口术后感染率为13．6％；动脉插管感染率为27．6％，静脉插管感染率为25．5％，泌尿道插管感染率为30．3％，呼吸道感染率为20．8％ ，全麻感染率为42．6％ 。结论：医院感染与患者年龄、感染时间和抗菌药物使用情况无关。与性别、部位分布、手术切口类型、侵入性操作、危险指数等级及病原微生物有密切关系。

Analysis of risk factors for nosocomial infection of urological surgical department.

Purpose:To explore the risk factors for nosocomial infection of urological surgical department.Method:2 976 cases of urological surgical patients was investigated retrospectively for the nosocomial infective prevalence in urological surgical department from the April 1996 to April 1999.Result:Nosocomial ratio in urological surgical department was 4.87 %,in which 73.1 % for male and 26.9 % for female.The infective sites are lower respiratory tract,surgical wound,urinary tract,gastrointestinal tract,upper respiratory tract and skin soft tissues in turn,infection rates were 4.38 %, 10.4 %, 13.6 %, 27.6 %, 25.5 %, 30.3 %, 20.8 %, 42.6 % for clean wound,dirty wound,infection wound,artery catheter,venouse catheter,urinary tract catheter,respiratory tract,and general anesthesia respectively.Conclusion:The nosocomial infection was not related to age,infection time and the usage of antibiotics;but was closely related to gender,surgical sites,surgical wound type,invasive operation,the degree of tisk index and micropathogens.
