医院多药耐药菌感染的监测与分析

目的了解医院多药耐药菌(MDRO)的分布情况,为临床治疗和合理制定医院感染控制措施提供依据。方法使用VITEK-AMS全自动微生物分析仪进行菌种鉴定和药敏试验,对分离到多药耐药菌的分布进行调查分析。结果共分离出病原菌2527株,多药耐药菌617株,占24.4%;617株多药耐药菌中革兰阳性球菌占20.1%,革兰阴性杆菌占79.9%;前3位是鲍氏不动杆菌、耐甲氧西林金黄色葡萄球菌和大肠埃希菌;主要分布在ICU、神经外科和神经内科,分别为30.6%、11.7%和10.5%;年龄最大90岁,最小33 d,>60岁占56.1%;引起医院感染的部位主要是呼吸道和泌尿道。结论临床应合理应用抗菌药物,加强对老年及危重患者多药耐药菌的监测与控制,特别要关注泛耐药的产生与流行。

Monitoring and analysis of multidrug-resistant organisms in hospital

OBJECTIVE To investigate the distribution of multi-drug resistant organisms(MDRO) with various resistance,to provide scientific basis for the establishment of effective medical protection and control measures,and provide useful information for clinical management.METHODS The medical sensitivity and identification of the isolated MDRO were determined by Vitek-AMS.RESULTS A total of 617 strains of MDRO were isolated from 2527 strains of pathogenic bacteria,of which the G+ were 20.1%,G-were 79.9%.The top 3 pat...
