摘要
目的了解重症监护病房(ICU)血流感染流行的危险因素。方法对ICU2007年3-8月发生血流感染24例进行调查,对ICU中心静脉置管的操作和护理进行跟踪督查。结果感染主要发生在置管7 d内,15例占62.5%;产超广谱β-内酰胺酶(ESBLs)肺炎克雷伯菌、产气肠杆菌、鲍氏不动杆菌是血流感染的主要病原菌;ICU患者基础疾病重;多处血管内置管操作及操作时不恰当的无菌屏障是导致血流感染的主要危险因素。结论ICU患者病情危重,严格掌握中心静脉置管适应证与留置时间;中心静脉置管后输液严格的无菌技术等是预防血流感染的主要措施。
OBJECTIVE To investigate risk factors of bloodstream infection in ICU. METHODS From May 2007 to Aug 2007, the operation of central venous catheter and the medical attendance of 24 cases with bloodstream infection were retrospectively analyzed. RESULTS Fifteen cases with infection （62. 5 %） were found in 7 days; ESBLs-producing Klebsiella pneumoniae, Enterobacter, and Acinetobacter baumannii were the major pathogens. The major risk factors included severe underlying diseases, endovascular catheter operation and incorrect asepsis barrier. CONCLUSIONS The patients are severe in ICU. In order to control and prevent infection in ICU, effective measures should he taken, including taking strict aseptic treatment in central venous catheter and the medical attendance of catheters, and strengthen hygiene administration.
