中医院脊柱内固定手术患者术后切口感染特点及危险因素研究

Study on the characteristics of surgical site infection with spinal instrumentation and risk factors in a traditional Chinese hospital

目的了解中医院脊柱内固定手术患者术后切口感染的发病情况及危险因素,为预防手术部位感染提供依据。方法通过前瞻性监测和统计学分析方法,对某中医院2013年度住院接受脊柱内固定手术患者术后切口感染情况进行了调查与分析。结果共调查418例实施脊柱内固定手术的患者,查出手术部位感染患者11例,感染发生率为2.63%。单因素分析显示,年龄、术前血糖值、术中失血量、术前住院天数等4个因素与脊柱内固定手术后手术部位感染有关;多因素回归分析发现,术前血糖值和术中失血量是手术部位感染发生的独立危险因素。结论该中医院脊柱内固定手术患者发生手术部位感染与多个因素相关,术前合理控制血糖、减少术中失血对于预防和控制手术部位感染有重要意义。

Objective To know the prevalence of surgical site infection（ SSI） in patients with spinal instrumentation surgeon in a traditional Chinese hospital and explore the risk factors of infection,in order to provide data basis for SSI infection prevention. Methods Prospective monitoring and statistical analysis were used to investigate and analyze the infection of the incision in patients with spinal instrumentation surgeon in a traditional Chinese hospital in 2013. Results Totally there are 11 cases with SSI in the 418 patients with spinal instrumentation surgeon. The surgical site infection rate was 2. 63%.The result of univariate analysis revealed that age,preoperative blood glucose level,intraoperative blood loss,length of stay before surgeon were correlated with SSI. The result of multivariate logistic regression analysis revealed that preoperative blood glucose level and the intraoperative blood loss were the independent risk factors of SSI. Conclusion SSI in patients in this hospital with spinal instrumentation surgery is associated with many factors. We think reasonable blood glucose control and less intraoperative blood loss are significant in preventing and controlling SSI in patients with spinal instrumentation surgery.
