恶性肿瘤合并医院获得性肺炎常见病原菌分布及其耐药性分析

目的 观察恶性肿瘤患者并发医院获得性肺炎(HAP)常见病原菌分布及其耐药性的特点,为临床治疗提供指导.方法 对医院102例恶性肿瘤并发HAP患者的合格痰标本进行培养及药敏试验,对病原菌分布特点和耐药性进行分析.结果 102例恶性肿瘤并发HAP检出病原菌121株,革兰阴性杆菌占60.3％,前5位细菌分别是铜绿假单胞菌、鲍氏不动杆菌、肺炎克雷伯菌、大肠埃希菌、嗜麦芽寡养单胞菌,产ESBLs肺炎克雷伯菌检出率41.2％,产ESBLs大肠埃希菌检出率为45.5％,对常用抗菌药物显示较高的耐药率,对哌拉西林/他唑巴坦、头孢哌酮/舒巴坦或碳青霉烯类、阿米卡星较敏感；革兰阳性球菌占22.3％,MRSA占金黄色葡萄球菌75.0％,MRCNS占凝固酶阴性葡萄球菌62.5％,对万古霉素、替考拉宁、利耐唑胺敏感率达100.0％;真菌占17.4％,以白色假丝酵母菌占绝大多数.结论 恶性肿瘤患者并发医院获得性肺炎的患者常见病原菌以革兰阴性杆菌为主,革兰阳性球菌及真菌感染比例越来越高,且耐药现象严重,应加强病原学及耐药性监测,指导临床合理用药,减少耐药性的发生.
