目的 了解天津市儿童医院医院感染现状,为预防和控制医院感染提供依据.方法 对2005年上半年该院6101例住院患者的临床资料和2005年全年分离的医院感染病原菌进行回顾性调查,以了解感染率及致病菌耐药情况.结果 医院感染总发生率为3.47%(212/6101),其中,普通医院感染率为2.95%(180/6101),外科伤口感染率为2.66%(32/1204).在全部感染中呼吸道感染最为常见(119/212,56.1%).造成医院感染的前6位病原菌依次为大肠埃希菌、凝固酶阴性葡萄球菌、肠球菌、肺炎克雷伯菌、金黄色葡萄球菌和铜绿假单胞菌.结论 调查显示,细菌多药耐药较常见,应加强对医院感染和抗生素耐药情况的监控.
abstract：
objective to investigate the prevalence of nosocomial infections in tianjin children's hospital and to provide database for monitoring and control of nosocomial infection.methods the medical records of 6101 children admitted in the first half of 2005 and the laboratory results of isolated bacteria from clinical samples in 2005 were retrospectively investigated.results the total nosocomial infection rate was 3.47%(212/6101),in which the surgical nosocomial infection rate was 2.66%(32/1204)and 2.95%(180/6101)infections were caused by non-surgical incisions.respiratory tract was the most frequent infection site(119/212,56.1%).several opportunistic pathogens were responsible for the major nosocomial infections,they were escherichia coli,coagulase negative staphylococcus,enterococcus,klebsiella pneumonia,staphylococcus aureus and pseudolnonas aeruginosa.conclusion the pathogenic isolates for the infections show high resistance to most antibiotics.monitor and control of the incidence of nosocomial infections and resistance to antibiotics should be enforced.
