脊柱手术后切口感染的危险因素

Risk factors for surgical site infections after spine surgery

目的:分析脊柱手术后切口感染的相关因素,为临床防治提供依据。方法:回顾2010年6月至2013年5月我院行脊柱手术2 083例患者的临床资料,收集并进行统计分析。结果:发生了38例不同程度的切口感染,总体发生率为1.8%。单因素分析显示,性别、吸烟史、长期使用药物史等11项因素与脊柱手术术后切口感染的发生有关。进一步Logistic回归分析显示性别、住院时间、脊柱手术创伤指数与切口感染的关系更密切。结论:脊柱手术后切口感染的发生与多种因素有关,性别、住院时间、脊柱手术创伤指数是独立的危险因素。

Objective To analyze the related factors of surgical site infections after spine surgery so as to provide basis for clinical prevention. Methods We retrospectively reviewed the clinical data on 2,083 patients who had undergone spine surgery during the period of June 2010 to May 2013, and then conducted a statistica analysis. Results A total of 38 patients developed surgical site infections. The incidence of surgical site infections after spine surgery was 1.8%. 11 risk factors including gender, history of smoking, and history of prolonged uses of medications were related to surgical site infections The logistic regression analysis indicated that surgical site infections were more closely related to gender, length of hospital stay, and spine surgical invasiveness index. Conclusions Multiple factors can be attributed to surgical site infections after spine surgery. Gender, length of hospital stay, and spine surgical invasiveness index are the independent risk factors.
