综合性ICU病原菌临床分布特征分析

目的 探讨综合性ICU医院感染病原菌的临床分布特点.方法 回顾性分析154株病原菌的资料,分析其标本来源、科室分布及种类分布.结果 154株病原菌主要来源于痰液、导管和血液,分别占53.9％、15.6％、11.7％；科室分布以呼吸内科、胸外科、神经外科及骨科为主,分别占29.9％、18.2％、14.3％及13.0％；共分离出革兰阴性菌107株、革兰阳性菌41株和真菌6株,以大肠埃希菌、金黄色葡萄球菌和铜绿假单胞菌为主,分别占27.9％、22.1％、17.5％.结论 ICU感染仍以革兰阴性菌为主,金黄色葡萄球菌所占比重较大,临床应加强重点科室的检测.

Clinical distribution of pathogens isolated from general ICU

OBJECTIVE To explore the clinical distribution features of pathogens isolated from general ICU department. METHODS The clinical data of 154 strains of pathogens were reviewed,and the specimen orientation,department distribution,and species were analyzed. RESULTS Totally 154 strains were mainly cultured from sputum(53.9%),catheter(15.6%),and blood(11.7%),and they most distributed in departments of respiratory medicine(29.9%),thoracic surgery(18.2%),neurosurgery(14.3%),and orthopaedics(13.0%).154 strains were...
