成人败血症249例回顾性临床分析

目的 分析成人败血症的临床特点及病原菌分布、耐药性特点,为临床血流感染的防治提供依据.方法 对医院1999～2008年成人败血症249例进行回顾性临床分析.结果 患者院内感染败血症154例,占61.8%;总死亡率34.5%;最常见的临床并发症依次为恶性肿瘤、糖尿病及粒细胞缺乏;病原菌检出革兰阴性菌146株,占58.6%,革兰阳性菌82株,占32.9%,真菌占8.4%,最常见的病原菌依次为大肠埃希菌(29.7%),金黄色葡萄球菌(14.5%)和肺炎克雷伯菌(11.7%);大肠埃希菌及肺炎克雷伯菌产ESBLs率分别为43.2%和42.9%;葡萄球菌属中耐甲氧西林葡萄球菌占69.8%;亚胺培南对肠杆菌科细菌、万古霉素对革兰阳性球菌耐药率均为0.结论 成人败血症病例逐年增加,其中社区感染败血症的比例近年来有所增加;分离的病原菌耐药程度较高,但未发现耐碳青酶烯类肠杆菌科细菌及耐万古霉素革兰阳性球菌.
