急诊重症监护病房耐甲氧西林金黄色葡萄球菌定植与感染调查分析

目的 调查急诊重症监护病房( EICU)耐甲氧西林金黄色葡萄球菌(MRSA)定植与感染状况,为实时控制医院感染暴发流行提供参考依据.方法 对临床资料进行分析,环境卫生学监测采样方法参照卫生部《消毒技术规范》,制定干预措施.结果 6例MRSA定植和感染病例平均年龄62.5岁,原发性基础疾病重；41份环境标本和16份来自接触阳性患者的医务人员手部标本中均分离到病原菌,阳性率分别为24.39％和18.75％.结论MRSA定植是造成医院感染的源头,将仅出现定植的病例并入感染病例进行统计分析,可实时监控院内医院感染的暴发.

Research and analysis of colonization and infection of methicillin-resistant Staphylococcus aureus in an emergency intensive care unit

Objective To investigate the colonization and infection of methicillin-resistant Staphylococcus aureus(MRSA) in an emergency intensive care unit(EICU) and provide evidence for real-time control of the outbreak of Nosocomial infection.Methods Clinical data was analyzed.The sampling process for sanitary monitoring used was in accordance with the Technical Standard for Disinfection by the Ministry of Public Health.Intervention measures were made.Results There were 6 samples of MRSA colonization and infection of MRSA,the average age of which was 62.5 years.Their primary diseases were severe.41 environmental samples and 16 samples from the hands of medical personnel who had contact with positive patients showed positive results,with the isolation rate of 24.39% and 18.75% respectively.Conclusion The MRSA colonization is the original cause of Nosocomial infection.Incorporation of the cases with colonization only into infection cases when doing statistical analysis can help to monitor the outbreak of Nosocomial infection in real time.
