摘要 目的调查临床医务人员治疗护理耐甲氧西林金黄色葡萄球菌(methicillin-resistant staphylococcus aureus,MRSA)感染患者后的手耐甲氧西林金黄色葡萄球菌污染情况及比较常用消毒剂对耐甲氧西林金黄色葡萄球菌的消毒效果。方法选择240名为耐甲氧西林金黄色葡萄球菌感染患者实施治疗、护理操作后的医务人员为研究对象,根据采集标本时间分为3组,分别采用0.2%过氧乙酸、0.5%洗必泰和75%酒精擦拭双手消毒,消毒前后采集医务人员手标本。结果240名医务人员为耐甲氧西林金黄色葡萄球菌感染患者实施治疗、护理操作后的手耐甲氧西林金黄色葡萄球菌检出率为37.5%,其中护士检出率最高(43.1%);医务人员实施不同的操作手耐甲氧西林金黄色葡萄球菌的检出率最高的操作为换药(56.2%);对不同部位感染耐甲氧西林金黄色葡萄球菌的患者实施操作,医务人员手耐甲氧西林金黄色葡萄球菌检出率中伤口感染患者最高(68.2%);0.2%过氧乙酸、0.5%洗必泰和75%酒精对耐甲氧西林金黄色葡萄球菌均具有良好的消毒效果,未发现耐药。结论医务人员治疗护理耐甲氧西林金黄色葡萄球菌感染患者后的手是耐甲氧西林金黄色葡萄球菌感染的重要传播途径,需提高其手卫生依从性,以预防和控制耐甲氧西林金黄色葡萄球菌在医院内的传播。 Objective To investigate the MRSA-carrying hand of medical staff and to compare its disinfection with frequently-used disinfectants. Methods There were 240 medical staff who conducted treatment for patients infected by MRSA in the study and they were divided into three groups based on different disinfectants they applied after the treatment. Samples from hand were collected before and after disinfection. Results The detection rate of MRSA reached 37.5% with a highest detection rate among nurses of 43.1% and MRSA existed mostly after dressing (56.2%) and after conducting treatment for patients with wounds (68.2%). The disinfection with 0.2% peracetic acid or 0.5% Chlorhexidine or 75% alcohol was effective. Conclusion Hands of medical staff serve as an spread approach of MRSA, as a result, it is important to improve the compliance with hand hygiene of medical staff.
