洁净手术室医院感染的现状分析

Current status of nosocomial infections in clean operating rooms

目的分析洁净手术室医院感染的现状,总结降低洁净手术室医院感染的措施,以期降低洁净手术室医院感染率,提高医疗质量。方法选取2011年1月-2012年12月医院洁净手术室患者4698例,对手术间细菌监测情况采用SPSS13.0软件进行统计分析,对洁净手术室患者临床资料采用t或χ2检验,多因素分析采用logistic回归分析,探讨洁净手术室医院感染的危险因素。结果年龄≥60岁、Ⅲ类切口、合并糖尿病、低蛋白血症的患者发生医院感染率明显高于年龄<60岁、Ⅰ类和Ⅱ类切口以及不合并糖尿病、低蛋白血症的患者,差异有统计学意义(P<0.05);经过多因素分析,年龄、切口分类、是否合并糖尿病和低蛋白血症是洁净手术室手术患者发生医院感染的独立危险因素(P<0.05)。结论针对洁净手术室内医院感染的特点,制定相应的干预对策,尽量减少患者的易感因素,同时提高对手术室的管理效率,可有效减少医院感染的发生率。

OBJECTIVE To analyze the current status of nosocomial infections in clean operating rooms and put forward prevention measures so as to reduce the incidence of nosocomial infections in the clean operating rooms and improve the medical quality.METHODS A total of 4698cases of clean operating room patients,who were treated in the hospital from Jan 2011 to Dec 2012,were enrolled in the study,then the monitoring of bacteria in the clean operating room was statistically analyzed with the use of SPSS13.0software,the clinical data of the patients were analyzed through t-test or chi-square test,the multivariate logistic regression analysis was performed,and the risk factors for the nosocomial infections in the clean operating rooms were analyzed.RESULTS The incidence of nosocomial infections in the patients with more than 60years of age,typeⅢincision,complication of diabetes,or hypoalbuminemia was significantly higher than that in the patients with less than 60years of age,type I or typeⅡ incision,without complication of diabetes or hypoalbuminemia,the difference was significant（P0.05）.The multivariate analysis showed that the age,types of incision,complication of diabetes,and complication of hypoalbuminemia were the independent risk factors for the nosocomial infections in the clean operating room patients（P0.05）.CONCLUSIONIt is an effective way to formulate corresponding interventions according to the characteristics of nosocomial infections in the clean operating rooms,try to reduce the susceptible factors,and improve the efficiency of management so as to effectively reduce the incidence of nosocomial infections.
