急诊重症病房置管患者医院感染病原菌及其耐药性分析

目的 探讨急诊重症监护病房（EICU）置管患者医院感染的病原菌群及药敏结果,为临床合理应用抗生素提供依据.方法 回顾性分析132例EICU患者发生医院感染的临床资料及下呼吸道分泌物、血液、尿道分泌物细菌培养情况.结果 EICU中置管患者医院感染发生率为17.19%;病原菌以G-菌为主,其中铜绿假单胞菌、鲍曼不动杆菌、肺炎克雷伯菌、大肠埃希菌及金黄色葡萄球菌为主要致病菌,且耐药严重.结论 加强EICU置管患者病原学监测,合理应用抗生素,是降低医院感染发生率的关键.

The pathogen of nosocomial infection and its drug resistance in nosocomial infection patients with catheter in EICU

Objective To investigate the pathogen of nosocomial infection and antimicrobial susceptibility results in nosocomial infection patients with cather in emergency intensive care unit （EICU）. Methods The clinical data and the conditions of bacterial cultures in lower respiratory secretions ,blood and urethral discharge of 132 nosocomial infection patients in EICU were retrospectively analyzed. Results In EICU patients with catheter nosocomial infection rate was 17. 19%. Main pathogens were G-bacteria,including Pseudomonas aeruginosa, Acinetobacter banmannii, Klebsiella pneumoniae, Escberichia coli and Staphylococcus aureus as the main pathogenic bacteria and their drug resistance were seriously. Conclusion In order to reduce nosocomial infection rate in EICU patients with catheter pathogen monitoring and rational use of antibiotics should be strengthened.
