ICU与非ICU感染患者病原菌分布及耐药性对比分析

目的分析重症监护室（ICU）与非ICU患者感染病原菌的分布和耐药情况，为临床抗感染治疗提供依据。方法对2006年5月-2007年5月临床各科室送检标本进行细菌分离培养与鉴定，并对ICU与非ICU患者感染病原菌分布及耐药性进行对比分析。结果从ICU患者标本中分离培养出病原菌150株，其中非发酵菌总构成比为40.67％（61/150）；非ICU患者标本分离培养出病原菌495株，非发酵菌总构成比为17.98％（89/495）。ICU患者非发酵菌检出率高于非ICU患者（χ2 ＝33.20，P＜0.01）。ICU患者分离的主要病原菌依次为真菌（21.33％）、铜绿假单胞菌（17.33％）、大肠埃希菌（12.67％）；非ICU患者分离的主要病原菌依次为真菌（20.61％）、大肠埃希菌（17.98％）、金黄色葡萄球菌（10.30％）。ICU患者感染的鲍曼不动杆菌和金黄色葡萄球菌耐药较严重；第三代头孢菌素在治疗革兰阴性杆菌感染时，ICU与非ICU患者耐药差异较大。结论ICU患者非发酵菌检出率高，其感染的病原菌耐药严重，应加强管理与监测。

Distribution and drug resistance of pathogens isolated from patients in intensive care units and non intensive care units

Objective To analyze the distribution and drug resistance of pathogens isolated from patients in intensive care units( ICUs) and non-ICUs, so as to provide evidence for clinical anti-infective treatment. Methods Bacterial strains from patients in clinical departments from May 2006 to May 2007 were isolated and identified, pathogenic distribution and antimicrobial resistance between ICUs and non-ICUs were compared and analyzed.Results One hundred and fifty strains were isolated from patients in ICUs, the con...
