MRSA医院获得性肺部感染流行趋势

Epidemic Tendency about MRSA in Hospital-acquired Lung Infection

目的 研究MRSA院内获得性肺部感染流行趋势和防治对策。方法 对重症监护病房患者MRSA肺部感染及传播因素进行监测。结果 金黄色葡萄球菌中MRSA占的比例逐年升高 ,尤其重症监护病房肺部感染的患者痰中MRSA检出率为 75 % ;医护人员工作中手、呼吸机管道MRSA阳性率为 4 0 %～ 5 0 % ,水龙头、拖布MRSA阳性率为 5 0 %～ 10 0 % ;通过环境消毒 ,物表未检出MRSA。结论 MRSA是医院获得性感染重要致病菌 ,在重症监护病房引起肺部感染流行 。

OBJECTIVE To investigate the epidemic tendency and preventive measures about MRSA in hospital acquired lung infection. METHODS To monitor patients who had MRSA infection of lung and disseminated agent in intensive care unit (ICU).
