摘　　要：目的探讨腰椎后路全椎板减压椎间植骨融合内固定术(PLIF)老年患者手术部位感染(SSI)的病原学特点及危险因素。方法收集1168例PLIF老年患者临床资料,分析SSI发病率、病原学特点、危险因素。结果PLIF老年患者SSI发生率为4.5%,金黄色葡萄球菌最常见(40.4%)。身体质量指数>25 kg/m^(2)、合并糖尿病、手术时间>3 h、手术节段数>3、17:00后手术是SSI独立危险因素(P<0.05)。结论PLIF老年患者SSI发生率较高,独立危险因素较多;最常见病原菌是金黄色葡萄球菌。Objective To analyze the etiological characteristics and risk factors of surgical site infection(SSI)in elderly patients with posterior lumbar interbody fusion(PLIF).Methods Clinical data of 1168 elderly patients with PLIF were collected.The incidence,etiology and risk factors of SSI were analyzed.Results The incidence of SSI in elderly patients with PLIF was 4.5%,with Staphylococcus aureus being the most common(40.4%).BMI>25 kg/m^(2),diabetes mellitus,operation time>3 h,operative vertebrae>3,and operation after 17:00 were independent risk factors of SSI(P<0.05).Conclusions The incidence of SSI in elderly patients with PLIF is relatively high,with multiple independent risk factors.S.aureus is the most common pathogen.
