医院重症监护室病原菌感染特点及耐药性分析

Analysis of Bacterial Infection and Antibiotic Resistance in ICU

目的:了解重症监护病房(ICU)病原菌感染特点及耐药特性。方法:对我院ICU病房2004年1月至2006年9月各类感染标本中分离的578株病原菌分析整理,并对其耐药性进行分析。结果:578株病原菌感染来源前3位分别是:痰465例(占80.5%)、其次为血19例(占3.3%)和尿19例(占3.3%);感染病原菌中以革兰氏阴性杆菌为主,427株(占73.6%),其次为酵母菌109株(占18.8%)革兰氏阳性球菌44株(占7.6%),在革兰氏阴性杆菌中非发酵菌291株(占68.1%),肠杆菌科细菌136株(占31.9%),常用抗菌素中:耐药率>50%的有氨苄西林、复方新诺明;亚胺培南对肠杆菌科的细菌耐药率为0%,但对非发酵菌有较高的耐药率。结论:ICU中感染严重,存在普遍的耐药性,根据微生物药敏结果选择用药很是必要。

Objective:To investigate the characteristic of pathogens infection and drug resistance isolated from intensive care unit(ICU).Methods 578 strains of pathogens were analyzed,which were isolated from January 1,2004 to September 30,2006 in intensive care unit(ICU)of our hospital.Antimicrobial susceptibility test was done to know the drug resistance.Results The speciments predominant were sputums where 578 strains of pathogens isolated,465(accounted for 80.5%),followed by blood,19(accounted for 3.3%);urine,19(a...
