手术室医院感染危险因素的logistic回归分析

Logistic regression analysis of risk factors of hospital infection in operating room

目的：研究手术室医院感染的危险因素，并探讨其相应的护理措施。方法对2011年1月至2013年6月期间接受外科手术治疗的1985例患者的临床资料进行回顾性分析，发现63例医院感染患者。收集上述患者的临床资料，包括性别、年龄、是否合并全身慢性疾病、手术是否为侵入性操作方式、麻醉方式、术后是否使用抗菌药物、手术室空气菌落数、手术无菌操作情况、手术室消毒情况、手术器械消毒情况等，并对上述资料进行logistic回归分析。结果年龄、基础疾病、侵入性操作、麻醉方式、手术室空气洁净度等是导致医院感染发生的影响因素。结论手术时应注意尽量减少导尿管置留时间，缩短手术麻醉插管时间和术后留置的时间，加强手术室及手术器械的消毒灭菌等环节，减少医院感染的发生。

Objective To study the risk factors of nosocomial infections in the operating room, and to explore the appropriate care measures. Methods The clinical data of 1 985 patients receiving surgical treatment from January 2011 to June 2013 were analyzed and 63 cases with hospital infections were found within them. The clinical data of the 63 patients were collected, including gender, age, systemic chronic diseases, invasive surgical operation, anesthesia, the use of antimicrobial drugs, operating room air colonies, surgical aseptic conditions, operating room disinfection, disinfection of surgical instruments, etc. , and the data were analyzed by Logistic regression analysis. Results Age, underlying diseases, invasive procedures, anesthesia and operating room air cleanliness were the risk factors of nosocomial infection. Conclusion We should shorten catheter indwelling time and shorten the time of anesthesia and postoperative indwelling catheterization, and strengthen sterilization of operating room and surgical instruments to reduce hospital infection.
