重症监护病房耐甲氧西林金黄色葡萄球菌感染的预防与控制

目的 调查分析医院重症监护病房(ICU)患者耐甲氧西林金黄色葡萄球菌(MRSA)交叉感染的原因,并探讨预防控制对策.方法 对2008年6月25日-8月1日ICU感染MRSA的两例患者进行病原学检查及环境卫生学监测.结果 从ICU医务人员手、床头桌、负压吸引器开关旋钮、墙壁供氧装置开关旋钮、吸痰用生理盐水等均检出MRSA,分离率分别为37.5%、20.0%、54.5%、37.5%、87.5%.结论 ICU患者易感染MRSA,该细菌耐药性强,治疗困难,可通过合理用药,严格无菌操作、加强消毒隔离措施可预防及控制交叉感染.

Prevention and Control of Methicillin-resistant Staphylococcus aureus Infection in ICU

OBJECTIVE To investigate and analyze the cause of the cross infection of Methicillin-resistant Staphylo-coccus aureus (MRSA) in ICU patients , and to apporach its preventive and control measures. METHODS Eiological inspection and sanitary monitoring have been done in ICU where there were two MRSA patients from June 6th, 2008 to August 1st, 2008. RESULTS MRSA has been detected on the hands of the ICU medical staff,on the bed-desks, on the switches of the vacuum extractor and gas supply unit on the wall, and in the NS for inhaling sputum. The separation rate were 37.5%, 20.0%, 54.5%, 37.5%, 87. 5%. CONCLUSIONS ICU patients are prone to be infected with MRSA, which has a strong drug resistance and the infection is difficult to be treated. The cross infection can be prevented and controlled by rational administration, sterile operation and insulation.
