脊柱外伤后内固定术后感染的危险因素的分析

Risk factors of infection after orthopedic internal fixation in patients with spinal trauma

目的分析脊柱外伤内固定术后感染的危险因素,以期为临床诊疗提供参考。方法回顾性分析2008年1月一2014年1月在本院接受脊柱手术的外伤患者的临床资料。依据患者术后是否发生感染分为感染组和未感染组。结果共纳入212例患者,其中感染组患者45例,未感染组患者167例。单因素分析显示:感染组患者年龄≥60岁、多处骨折、污染切口、开放伤口、手术时间≥4 h、使用激素以及合并糖尿病的患者比例显著高于非感染组(P<0.05)。Logistic回归分析发现:年龄≥60岁、污染切口、使用激素及合并糖尿病是脊柱手术后感染的独立风险因素(P<0.05)。结论对于高龄、使用激素、污染切口及合并糖尿病的脊柱手术患者应当更加注意预防术后感染。

Objective To analyse the risk factors of infection after orthopedic internal fixa-tion in patients with spinal trauma.Methods Clinical materials of spinal trauma patients with or-thopedic internal fixation were retrospectively analyzed.Results 212 patients were analyzed.45 patients had postoperative infection （Group A）and 167 patients without postoperative infection. The logistic regression analysis showed that age≥60 years,open wounds,use of glucocorticosteroids and combined diabetes were the independent risk factors of postoperative infection for the patients with spinal trauma.Conclusion More attentions should be paid on the spinal trauma patients with features of age≥60 years,open wounds,use of glucocorticosteroids and diabetes in order to low the postoperative infection.
