摘要 目的探讨重症监护病房患者下呼吸道感染非发酵菌菌群的分布特点及耐药性。方法选取2011年7月至2013年5月在我院重症监护病房院内感染的422例下呼吸道感染的患者的痰液标本进行细菌培养及耐药性分析。结果经过细菌培养,422名患者共分离出970株致病菌株,67例患者只感染一种菌株,162例患者感染两种菌株,193例患者感染两种菌株,84.12%为混合感染。鲍氏不动杆菌的感染率最高占所有感染菌株的32.47%,铜绿假单胞菌次之,为23.40%。对常见致病菌的耐药性进行分析可知,任何一种致病菌都对多种药物具有较高的耐药率。结论重症监护病房患者多为混合菌感染,鲍氏不动杆菌感染率最高,耐药率较高。
