【摘要】 目的 了解ICU病房病原菌感染特点，为预防和控制感染及合理用药提供依据。方法 收集该科2003年4月～2004年10月住院患者痰液标本做细菌培养。ATB自动细菌分析仪做鉴定和药敏试验。结果 共检出病原菌341株，其中绿脓假单胞菌111株，占32.6%；念珠菌71株，占20.8%；葡萄球菌66株，占19.4%；鲍曼不动杆菌56株，占16.4%；嗜麦芽窄食单胞菌18株，占5.3%；其他细菌19株，占5.6%。MRS检出率为86.3%。结论 ICU病房痰标本病原菌以绿脓假单胞菌检出率最高，真菌及鲍曼不动杆菌的检出有不断上升趋势，绿脓假单胞菌对常用抗生素耐药率在70%以上。加强ICU病房各种医疗操作的清洁消毒，防止院内感染，重视病原菌检出，合理应用抗生素非常重要。
