鄂尔多斯市中心医院重症监护病房医院感染病原菌监测

Surveillance of Bacteria of Nosocomial Infection from Intensive Care Units(ICU) in Erdos Central Hospital

目的：分析我院重症监护病房（ICU）呼吸道感染的流行病学及细菌耐药情况,指导临床合理使用抗生素。方法：对鄂尔多斯市中心医院ICU 2008年1月2009年7月住院患者395份痰液标本培养及药敏结果,进行细菌菌株及细菌耐药性回顾性调查、分析。结果：革兰阴性杆菌占60.5%,G^-菌中以铜绿假单胞菌、大肠埃希菌以及肺炎克雷伯菌为主;G^＋占30.2%,主要以葡萄球菌属为主,真菌占9.3%。在细菌耐药性方面,大多数G^-杆菌仍对泰能保持较高的敏感率,G^＋球菌对万古霉素敏感。结论：ICU中感染严重,存在普遍的耐药性,根据微生物药敏结果选择用药很有必要。

Objective：To analyse prevailing strains and drug resistance isolated from intensive care units（ICU） with respiratory tract infection patients,contributing to future clinical prevention and treatment.Methods：A total of 395 sputum strains and drug susceptibility of pathogens were retrospectively analyzed in the patients with pulmonary infection in our intensive care unit from January,2008 to July,2009.Results：Gram-negative bacteria accounted for 60.5%,Gram-positive bacteria for 30.2% and fungi for 9.3%.G^-bacteria mainly included Pseudomonas aeruginosa,Escherichia coli and Klebsiella pneumoniae.G^＋ bacteria mainly included Staphylococcus.The majority of G^-bacte ria showed high susceptibility to imipenem,G^＋ bacteria were susceptive to vancomycin.Conclusion：Most of gram-negative bacilli in ICU were seriously resistant.It is very important to select antibiotics correctly for infection of the patients in ICU according to the results of susceptibilitytests.
