目的:通过对ICU病区耐甲氧西林葡萄球菌(MRSA)感染进行流行病学调查,探讨其易感因素和护理对策,为预防和控制医院感染提供参考。方法:对2008年3月7～29日ICU病区感染MRSA的10例病人及医院环境进行了流行病学调查及护理分析。结果:ICU病区MRSA的感染率为47.62%,且环境中空气、陪护人员手、医务人员等亦培养出MRSA,通过耐药谱分析显示具有高度同源性。结论:该次MRSA感染为局部暴发流行。医院必须加强对护理人员及室内外环境监控,防止交叉感染,严格无菌侵入性操作和抗生素的使用,从而有效减少医院感染的发生。

Objective：To investigate the epidemic of metieill -resistant staphy locoeeus aureus （MRSA） in intensive care unit （ICU）, analyse the risk factors and its eountermea sures. The ways to prevent and treat this nosoeomial infection. Methods：The ease histories from 10 in patients and environment of hospital who developed MRSA infection in ICU form Mar. 7 to Mar. 29,2008 ,were studied retrospectively to find out the reason of the epidemia and its eountermea sures. Results ：The rate of MRSA infection was 47.6% in ICU. MRSA could be found the air, hands of accompanying persons, healthy eareworker et al. the MRSA spectrum euhured from is treatment based on the sputum culture results was in accordance with that in its environment. Conclusion：The MRSA infection was fulminate epiidemiologieal at a certain ward intensifying environmental, nursing, airy monitoring inside and outside ICU, avoiding across infection, adopting aseptic courses in invasive procedures and keeping good utilization principles for antimierobial drugs, decline nosoeomial infection of the MRSA in ICU.
