310株铜绿假单胞菌的分布及耐药性分析

目的：了解2008年1月～12月医院分离的铜绿假单胞菌分布及其耐药情况,以指导临床合理用药。方法：收集临床分离的铜绿假单胞菌,利用MicSCAN-4半自动细菌鉴定和药敏系统分析仪及NC31G-鉴定板进行细菌鉴定及药敏试验,对临床常用15种抗菌药物的耐药性进行分析。结果：铜绿假单胞菌主要分离于痰液中以呼吸道感染为主,主要分布在重症监护室、呼吸科、肿瘤科,对头孢噻肟、头孢西丁、头孢唑啉3种药物的耐药率均大于50％,对头孢他啶、哌拉西林／他唑巴坦、耐药率均低于10％。结论：铜绿假单胞菌易产生多重耐药,加强耐药性监测,依据药敏结果合理选用有效的抗菌药物,控制院内感染,同时为临床提供最新的耐药性．资料。
