摘要
摘要目的评价医院重症监护病房(ICU)非发酵革兰阴性杆菌感染的分布、耐药情况,为临床合理应用抗菌药物提供依据.方法采集非发酵革兰阴性杆菌感染患者的培养结果进行回顾性分析.结果ICU临床分离出非发酵革兰阴性杆菌共２０５株,以呼吸道分离菌株最多,占８１．５％,其次为导管/血液;非发酵革兰阴性杆菌中铜绿假单胞菌占４６．８％,其次为鲍曼不动杆菌、嗜麦芽窄食单胞菌等;多药耐药菌(MDR)组与非MDR组比较,各项指标差异有统计学意义(P＜０．０１).结论非发酵革兰阴性杆菌在ICU重症患者中发生多药耐药的情况严重,加强ICU病原学监测,对降低医院感染发生率、指导临床合理应用抗菌治疗有重要意义.关键词非发酵革兰阴性杆;重症监护病房;细菌耐药性;临床分析AbstractObjectiveToevaluatethehospitalintensivecareunit(ICU)non－fermentingGram－negativebacilliinfectiondistribution,drugresistance,andtoprovideabasisforclinicalrationaluseofantimicrobialdrugs．MethodsThecollectionofnon－fermentingGram－negativebacillicultureresultsinfectedpatientswereanalyzedretrospectively．ResultsICUclinicalisolatesofnon－fermentinggram－negativebacillitotalof２０５,moststrainsisolatedintherespiratorytract,accountingfor８１．５％,followedbycatheter/blood;non－fermentingGram－negativebacteriaPseudomonasaeruginosaaccounts４６．８％,followedbyAcinetobacterbaumannii,Aeromonasmaltophiliabacteria;multidrugresistant(MDR)MDRcomparisongroupandnon－group,theindexdifferencewasstatistiＧcallysignificant(P＜０．０１)．ConclusionThecaseofnon－fermentingGram－negativebacillioccurinICUpatientswithseveremulti－drugresistanceisserious,strengtKheeynwIoCrdUspathogenmonitoring,reducinghospitalinfectionratestoguiderationaluseofantimicrobialtherapyisimportant．non－fermentativegram－negativebacteria;intensivecareunit;resistantofbacteria;clinicalanalysis中图分类号R３８文献标识码B文章编号１００８－６３１５(２０１５)１２－１０２９－０２
