摘　　要：目的了解某院部分高危病区医务人员、患者耐甲氧西林金黄色葡萄球菌(MRSA)携带和环境污染的状况,探讨医院内MRSA感染预防控制的策略。方法对某院7个高危病房的医护人员、陪护、患者的手及鼻前庭、医院病区环境进行随机采样培养。MRSA菌株鉴定按美国临床实验室标准化委员会(CLSI)的标准用头孢西丁(FOX)KB法。结果 787份医护人员及周围环境标本中,检出41(5.21%)株金黄色葡萄球菌,其中MRSA 11株,占26.83%;712份患者及周围环境标本中,检出68(9.55%)株金黄色葡萄球菌,其中MRSA43株,占63.24%。不同病区中,烧伤病房患者及周围环境MRSA检出率最高为16.50%。不同岗位中,护工工作服带菌率最高达7.14%。按职称统计,初级职称人员手和工作服MRSA检出率最高达2.23%。不同环境物体表面中,MRSA污染率最高的为呼吸机管口(11.76%),其次为水龙头和门/柜把手。患者带菌率最高的部位为烧伤黏膜(26.47%),其次为鼻前庭和手。结论医务人员、陪护、患者及病区环境均存在携带MR-SA的状况。应提高医护人员对MRSA在院内引起交叉感染的认识,加强保洁人员的管理及培训,积极做好环境卫生等基础工作,防止交叉感染。Objective To understand the status of MRSA carrying among health care workers and patients,and the environment in high-risk wards of a hospital and to explore prevention and control strategies of nosocomial MRSA infection.Methods Samples from the medical staff,the patients and environment in 7 high-risk wards of a hospital,were cultured.MRSA strains were identified by the CLSI standarded cefoxitin（FOX） KB method.Results In samples from 713 health care workers and the environment,41（5.75%） strains of SA were found including MRSA 11 strains（26.83%）.In samples from 639 patients and the environment,the detection rate of SA were 10.49% including 43 strains of MRSA（64.18%）.Conclusion It is critical to aware the situation of MRSA carrying in medical staff,patients and ward environment.We should improve hand hygiene compliance,strict implementation of sterile operating procedures and strengthen the management and training of cleaning staff to ensure effective environmental cleaning and disinfection.
