层流重症监护病房下呼吸道感染调查分析

Investigation and analysis on under respiratory way infection in the ICU of laminar air flow

目的:了解层流ICU下呼吸道病原菌分布构成及耐药状况,为降低医院ICU感染率及临床经验性用药提供依据。方法:用回顾性调查的方法对本院2006年9月～2007年12月的层流ICU病房住院患者下呼吸道标本的培养结果进行分析。结果:菌群以革兰阴性菌为主(54株),占58.06%,其次真菌(26株),占27.96%,革兰阳性菌(13株),占13.98%,下呼吸道院内感染率为17.55%。结论:层流ICU下呼吸道院内G^+感染率下降,特别是金黄色葡萄球菌,加强ICU下呼吸道感染的病原菌监测及统计分析对临床经验性治疗非常必要。

Objective：To search for the pathogen distribution and the change of drug resistance of under respiratory way infection in the ICU of laminar air flow,it was significant for empirical use of anti microbial agents in linic.nethods： Review the data of all patients who were in ICU between September 2006 and December 2007. Results：The most prevalent isolates of pathogens of nosocomial infection were still Gram-negative bacteria （58.06%）,then fungi （27.96%） an gram-positive bacteria （13.98%）.The rate of nosocomial infection was 17.55%. Conclusion：It is lower on the rate of under respiratory way infection in the ICU of laminar air flow,especially of staphylococcus.It is so important to strengthen the checking out of pathogen of low respiratory infection in ICU,that can guide the experiential treat.
