摘要 目的 了解医院产超广谱β-内酰胺酶(ESBLs)的革兰氏阴性杆菌耐药情况,指导临床用药。方法 收集2003年1月-2005年12月收治的感染性疾病患者标本,经培养,分离,共得革兰氏阴性杆菌744株,采用美国Microscanautoscan-4细菌分析仪进行鉴定和药敏分析,采用双纸片扩散法和确证试验对ESBLs进行检测。结果744株革兰氏阴性杆菌中检出产ESBLs株169株,检出率22.7%,其中,大肠埃希氏菌的检出率是36.3%,肺炎克雷伯氏菌的检出率是35.3%。肠杆菌科其他属和部分非发酵菌群也检出有不同程度的产酶株,产ESBLs菌株对19种常用抗菌药物的敏感性明显低于不产ESBLs的菌株(P〈0.05)。结论 产ESBLs的革兰氏阴性杆菌均具有极高的耐药性和多重耐药,治疗产ESBLs细菌引起的感染应首选亚胺培南、头孢派酮/舒巴坦和哌拉西林/他唑巴坦,其治疗效果好。
