摘要 目的探索在呼吸重症监护病房(RICU)内医院获得性肺炎(HAP)的危险因素与病原菌的分布情况。方法对85例接受呼吸机治疗的RICU内的患者,评估主要病因、合并症和并发症,监测内环境紊乱、RICU居住时间以及辅助呼吸类型,以及发生HAP的例数,细菌学监测结果。结果单因素分析,在RICU内的滞留时间和使用有创辅助通气是发生HAP的危险因素(P<0.05),多因素分析,使用有创辅助通气是发生HAP的危险因素(OR=18.581,P<0.05)。RICU内HAP的病原菌以革兰阴性菌为主(72%),以天然耐药菌为主。结论有创辅助呼吸和RICU居住时间是RICU内患者发生HAP的危险因素;RICU中HAP的病原菌以革兰阴性菌多见,而且多数对常用抗感染药物具有天然耐药的特性。
