摘　　要：目的：探讨ICU导尿管相关性尿路感染（ CAUTI）的感染率及危险因素。方法采用前瞻性监测，对2011年1月至2011年12月入住ICU﹥48 h、年龄﹥1岁的置管患者进行监测，并对发生CAUTI的患者进行危险因素分析。结果监测患者共1096例，其中接受置导尿管的患者872例，导尿管使用率为79.6%，置管日为9010 d，发生CAUTI 21例，CAUTI感染率为2.4%，平均日感染率为2.3/千日。CAUTI感染率与置管时间、置尿管次数均呈正相关（χ2=39.76，P﹤0.01；χ2=28.2，P﹤0.01），留置天数与置管次数是ICU的CAUTI的独立危险因素。结论严格执行手卫生、无菌操作、合理维护、尽早拔除导尿管是预防CAUTI发生的关键。Objective To investigate the infection rate and risk factors of catheter-associated urinary tract infections（CAUTI）. Methods From January 2011 to December 2011,the patients admitted in ICU longer than 24 hours and older than 1 year old were prospective monitored,and the risk factors of catheter-related urinary tract infections were analyzed. Results One thousand and ninety-six cases were monitored,in which 872 patients received catheters. The utilization rate of catheter was 79. 6%,and the days of catheter were 9010 d. Twenty-one patients had catheter-related urinary tract infections,and the infection rate was 2. 4%. The average daily infection rate was 2. 3/one thousand days. The CAUTI infection rate was positively correlated with the days of catheter and the times of catheter（χ2 =39 . 76 ,P﹤0. 01;χ2 =28 . 2 ,P﹤0 . 01 ）. The days of catheter and the times of catheter were the independent risk factors of catheter-associated urinary tract infections in ICU. Conclusions Strictly enforcing hand hygiene,aseptic technique,proper maintenance,removal of the catheter as soon as possible is the key to preventing CAUTI occurred.
