ICU发生院内感染的危险因素调查分析

The Risk Factors Analysis of Nosocomial Infection in ICU

目的:调查分析ICU发生院内感染的危险因素,并为预防ICU发生院内感染提供依据。方法:根据是否发生院内感染将入住本院重症监护病房的391例患者分为试验组和对照组。分别对所有患者进行手术治疗、气管切开治疗、气管插管治疗、泌尿道插管治疗、住ICU时间大于10 d等相应的操作,并对这些因素进行分析。结果:391例患者的ICU院内感染率为25.8%。多因素分析ICU院内感染,表明泌尿道插管治疗、气管插管治疗、住ICU时间大于10 d及机械通气时间大于5 d是ICU发生院内感染的危险因素。结论:避免院内感染,在加强防范意识、增强无菌观念的基础上,减少患者住院时间、减少机械通气时间、减少对患者的侵袭性操作等是减少院内感染的发生的有效措施。

Objective：To investigate the risk factors analysis of nosocomial infection in ICU,and provide the basis for the prevention of nosocomial infections in ICU.Method：391 patients in the intensive care unit of our hospital stay were divided into the experimental group and the control group according to the occurrence of nosocomial infections.The factors of treated with surgery,tracheotomy,endotracheal intubation,urinary tract intubation,ICU stay longer than 10 days and other appropriate action were analyzed.Result：Nosocomial infection rate of 391 patients was 25.8%. Multivariate analysis showed that ICU nosocomial urinary tract intubation,endotracheal intubation,ICU stay longer than 10 days and mechanical ventilation for more than 5 days were the nosocomial infection risk factors of ICU.Conclusion：To avoid nosocomial infections in ICU,the reduction of sterile hospitalization time,reduce duration of mechanical ventilation,reduce invasive operation based on strengthening awareness and enhance the concept are effective measures.
