Abstract : 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 文摘: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;类切口术后感染率为4 . 4 % ,类切口术后感染率为10 . 4 % ,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
