[摘要] 目的 分析临床深静脉导管(DVC)培养的病原学特征和耐药性。方法 回顾性分析瑞金医院2010年全年送检的深静脉导管的病原学及其耐药性。结果 991份送检导管病原学阳性154例(15.54%),检出病原菌176株,其中G+菌、G-菌和真菌各占41.47%、36.36%和22.17%;五种常见病原菌分别是表皮葡萄球菌(20.45%)、鲍曼不动杆菌(15.34%)、金黄色葡萄球菌(11.93%)、白色假丝酵母菌(11.36%)和铜绿假单胞菌(6.25%)。金黄色葡萄球菌中MRSA占94.12%,凝固酶阴性葡萄球菌中MRScn占69.44%;鲍曼不动杆菌、铜绿假单胞菌和肺炎克雷伯菌普遍存在多重耐药现象,鲍曼不动杆菌(26.92%)和铜绿假单胞菌(9.09%)甚至出现全耐药。结论 深静脉导管感染为院内感染,检出的病原菌多为耐药菌,无菌置管、加强导管的护理和加强病原学监测是控制DVC感染的关键。

[Abstract] Objective To investigate the characteristics of the organisims of deep-venous catheter(DVC) tip culture and their antibiotics resistance. Menthods The culture results All 991 DVC tip were analyzed retrospectivly from January to December of 2010. Rusults Among 991 cather tip cultures,154(15.54%) were positive with 176 microorganisms: G+bacteria accounted for 41.47%,G-bacteria 36.36%,and yeasts22.17%.The fivemost common microorganisms were Staphylcoccus epidemidis(20.45%), Acinetobacter baumanii(15.34%), Staphylococcus aureus(...
