ICU住院患者感染病原菌分布与耐药性监测

目的了解医院重症监护病房(ICU)住院患者感染病原菌分布及耐药现状,为临床合理用药提供依据。方法通过分离鉴定方法和K-B试验法,对某医院ICU住院患者送检病原学标本进行了病原菌分离鉴定和耐药性监测。结果 2011年7月-2012年7月,从该医院ICU住院患者送检的标本中共分离出病原菌1 109株,其中革兰阴性菌685株,占61.77%;真菌249株,占22.45%;革兰阳性菌175株,占15.78%。结论该医院ICU住院患者医院感染病原菌以革兰阴性菌占优势,且耐药率高,必须加强耐药菌监测与防范。

DISTRIBUTION AND DRUG RESISTANCE OF PATHOGENIC BACTERIA INFECTED BY INPATIENT OF ICU

Objective To evaluate the distribution and drug resistance of pathogenic bacteria causing nosocomial infection in ICU providing basis of clinic rational drug use.Methods The identification of isolated bacteria and K-B test were used to monitor the specimens from the ICU inpatients of one hospital for the pathogenic bacteria and their drug resistance.Results From July 2011 to July 2012,1 109 strains of pathogenic bacteria were isolated;685 strains were gram-negative and accounted for 61.77%;249 strains were fungi,the ratio of that was 22.45%;175 strains were gram-positive,which accounted for 15.78%.Conclusion Gram-negative bacilli are the main pathogenic bacteria in ICU,and the rate of drug resistance is high.It is important to enhance local surveillance of bacterial resistance.
