摘要
目的研究某院两个监护病房内耐甲氧西林金黄色葡萄球菌(MRSA)定植与感染状况,探讨MRSA定植与感染的危险因素及控制措施。方法对两个监护病房内住院患者(18例)的体表及血液、医护人员(20例)的体表及其周围环境进行采样培养,并分析其定植感染的危险因素,从而制定干预措施。结果 7例MRSA定植感染者中5例的年龄大于60岁,3例进行过手术治疗,5例使用侵入性操作,6例使用抗菌药物时间超过5天;20份医护人员体表标本和80份环境标本中均分离到MRSA菌株,检出率分别为35%和3.75%。结论侵入性操作及抗生素的大量使用等均为MRSA定植感染的危险因素,应适当减少;同时,应加强医务人员手卫生宣传教育,加强环境消毒,有效地预防和控制MRSA医院感染的发生。
Objective To study the conditions of colonization and infection of methieiUin-resistant Staphylococcus aureus （MRSA） among patients in 2 care wards, and to explore the risk factors and control measures of it. Methods Samples from the body and blood of inpatients （18 cases） and samples from the body of the medical staff（20 cases） and the environment in 2 care wards were cultured. The risk factors of nosocomial MRSA colonization and infection were analysed in order to formulate intervention measures. Results 7 cases of patients were detected with MRSA colonization and infection, with 5 cases older than 60 years old, 3 cases had been given operation, 5 cases had received invasive operation and 6 cases had used antibacterial drugs for more than 5 days; 20 samples from the body of the medical staff and 80 environmental samples were detected with MRSA, with the detection rate of 35% and 3.75% respectively. Conclusions Invasive operation and extensive using of antibiotics are both the risk factors of MRSA colonization and infection, which should be appropriately reduced. At the same time, we should strengthen the education of ＂washing hands＂ in medical staff and environmental disinfection to effectively ensure prevention and control of the nosocomial MRSA infection.
