摘　　要：目的了解引起重症监护室医院获得性感染的因素,采取预防措施,减少医院获得性感染的发生。方法对重症监护室40例次医院获得性肺炎的资料进行前瞻性研究,并通过环境卫生学监测,探讨其发生原因和传播途径。结果引起医院获得性肺炎的病原体主要为革兰氏阴性杆菌(77%),其中又以铜绿假单胞菌为主(35.7%)。环境卫生学监测从听诊器上检出多重耐药的铜绿假单胞菌,另外医务人员的手、集水瓶、手电筒和床头柜细菌超标。结论抗生素的广泛使用是以铜绿假单胞菌感染为主的医院获得性肺炎的主要原因;听诊器的污染是导致多名患者交叉感染多重耐药的铜绿假单胞菌的重要原因,医务人员的手是其传播途径。Objectives To take effective measures to reduce the incidence of nosocomial infections,we explored the factors contributing to nosocomial infection in Intensive Care Unit(ICU).Methods perspective study was conducted to investigate 40 nosocomial pneumonias in ICU,and sanitary science surveillance was performed to make clear the causes and transmission routes.Results The principal pathogen causing nosocomial pneumonia is Gram-Negative bacillus(77%),and Pseudomonas aeruginosa accounted the major part(35.7%).Sanitary Science Surveillance detected multidrug-resistant Pseudomonas aeruginosa from stethoscope.In addition,bacteria on hands of medical workers,catchment bottle,torch and bedside commode were overproof.Conclusions extensive use of antimicrobial is primary reason leading to nosocomial pneumonia infected by P.seudomonas aeruginose.Many patients infected multdrug-resistant Pseudomonas aerugiosa were mainly due to contaminated stethoscope.Hands of medical workers were the transmission route.
