全膝关节置换术后手术切口感染的影响因素分析

Analysison factors for surgical site infections after total knee arthroplasty

目的:分析全膝关节置换术(TKA)术后手术切口感染的影响因素。方法:回顾性分析2015年6月至2016年12月陕西省延安大学附属医院收治的110例行TKA患者的临床资料,采用单因素及多因素Logistic回归分析影响TKA术后手术切口感染的因素。结果:110例TKA术后手术切口感染率为7.3%,多因素Logistic回归分析结果显示,手术方式(OR=1.921)、异体输血(OR=2.103)、术后引流(OR=1.974)及手术时间(OR=1.401)是术后切口感染的独立危险因素(均P<0.05)。结论:TKA术后切口感染的发生与手术方式、异体输血、术后引流及手术时间有关,临床上应做好防护措施,尽可能消除危险因素,降低切口感染率。

Objective： To analyze the factors for surgical site infections （SSI） after total knee arthroplasty （TKA）. Methods： Clinical data from 110 patients undergoing TKA in our hospital from June 2015 to December 2016 were retrospectively selected. Univariate analysis and multivariable logistic regression analysis were used to analyze the factors for SSI after TKA. Results. The incidence of SSI was 7.3 %. Multivariable logistic regression analysis revealed that surgical procedures （OR= 1. 921）, allogenetic transfusion （OR=2. 103）, postoperative drainage （OR=1. 974） and operation time （OR=1. 401） were independent risk factors for SSI after TKA （P〈0.05）. Conclusion： SSI after TKA was correlated with surgical procedures, allogenetic transfusion, postoperative drainage and operation time.
