重症监护室金黄色葡萄球菌感染干预效果观察

Intervention efficacy observation on Staphylococcus aureus infections in intensive care unit

[目的]通过监测重症监护室金黄色葡萄球菌感染及耐药性变化,探讨重症监护室综合性干预对控制医院感染的作用。[方法]采用回顾性分析的方法,对某医院2011年和2012年重症监护室采取综合性干预措施前后,患者金黄色葡萄球菌的分离结果进行对比性分析。[结果]两年间金黄色葡萄球菌的分离率无明显差异(P>0.05),但耐甲氧西林金黄色葡萄球菌构成比明显下降,差异有统计学意义(P<0.05)。金黄色葡萄球菌对苯唑西林、环丙沙星和左氧氟沙星的耐药率明显下降(P<0.05)。两年间重症监护室金黄色葡萄球菌对万古霉素、替考拉宁、利奈唑胺、呋喃妥因和喹奴普汀-达福普汀敏感率最高,均达100.00%。[结论]通过综合性干预,重症监护室金黄色葡萄球菌感染情况得到改善,耐药率总体有所下降。

Objective] To discuss comprehensive intervention effect on the control of hospital infections in the intensive care unit （ ICU ） of a hospital by monitoring Staphylococcus aureus infections and their drug resistance . [ Methods] Comparative analysis was done retrospectively in separation results of Staphylococcus aureus between 2011 and 2012 in ICU patients of a hospital . [ Results] Between 2011 and 2012, there was no obvious difference found in relevance ratio of Staphylococcus aureus（P〉0.05）, but that of methicillin resistant Staphylococcus aureus was on the decline significantly （P〈0.05）.The drug resistance rates of Staphylococcus aureus to oxacillin, ciprofloxacin, levofloxacin were on the decline significantly（P 〈0.05）.The drug susceptibility rates of Staphylococcus aureus to vancomycin, teicoplanin, linezolid , nitrofurantoin and primaquine slave tianeptine/dafoe tianeptine were the highest , reaching up to 100.00%. [ Conclusion] By comprehensive intervention , Staphylococcus aureus infections in ICU have been improved and drug resistance rates on the decline as a whole .
