慢性充血性心力衰竭合并肺部感染临床特征分析

目的 探讨慢性充血性心力衰竭(CHF)合并肺部感染临床特征.方法 回顾性分析180例CHF住院患者的临床资料.结果 该组患者共发生肺部感染94例,占52.2%,入院前感染78例,占43.3%,医院感染16例,占8.9%;94例合并肺部感染的患者共分离出111株细菌,革兰阴性菌84株,占75.7%,革兰阳性菌27株,占24.3%;分布最多的3种细菌为铜绿假单胞菌(25.3%)、金黄色葡萄球菌(18.0%)和肺炎克雷伯菌(15.3%);主要细菌呈现出较高的耐药性;单因素分析显示,年龄≥60岁、住院时间≥30 d、侵入性操作、糖尿病和心功能Ⅲ、Ⅳ级为肺部感染的危险因素.结论 CHF合并肺部感染病以革兰阴性菌为主,应根据药敏试验选用合理的抗菌药物,同时应根据高危因素来控制和预防医院感染.
