老年人医院获得性肺炎的病原菌分布与临床特点

目的:探索老年人医院获得性肺炎的病原菌分布和特点。方法:对2003～2009年普通病房和重症监护病房(ICU)老年人医院获得性肺炎患者93例进行病原菌和药敏试验进行分析。结果:2003～2009年普通病房和ICU共分离出病原菌193株,排在前3位的依次的是大肠埃希氏菌(49株),肺炎克雷伯菌(45株),金黄色葡萄球菌(36株),占总菌株67.4%。其中G-杆菌对亚胺培南敏感,G+球菌对万古雷素敏感,对其他药物耐药性均较高。结论:老年人医院获得性肺炎耐药性较高,有必要采取积极的、正确的防治措施。

Objective： To investigate distribu- tion of pathogens and clinical characteristics with aged HAP. Methods： Pathogens were collected from patients with 93 cases aged HAP in ICU and common wards of our hos- pital during 2003 to 2009. The features of distribution and and antibiotic - resistance were analyzed. Resuhs：A total of 193 strains of pathogens were isolated from patients with aged HAP in ICU and common wards, The first 3 pathogens were Escheriehia eoli （49 strains ）, KlebsieUa pneamoniae （ 45 strains ） , Gram - positive cocci （ 36 strains）, by tuens, accounted for 67.4%. The drug resistant rates were higher to the most of antibiotics, But the resistant rate of Gram - negative bacill; to imipenem was lower,and the rate of Gram -positive cocci to vancomycin was also lower. Conclusion： The resistant rates were higher to the most of antibiotics, so it is necessary to take the ini- tiative to adop correctly preventive measure for patients with aged HAP.
