目的 探索结直肠手术手术部位感染(SSI)的危险因素,为制定SSI预防措施提供依据.方法 回顾性调查2013年6月-2016年6月某院胃肠外科结直肠手术患者,对影响感染的相关危险因素进行非条件logistic 回归分析.结果 397例结直肠手术患者中,67例发生SSI,SSI发生率为16.88％.logistic回归分析结果显示,吸烟、低清蛋白、手术医生年资＜5年、围手术期抗菌药物使用不规范、NNIS评分高5项因素是结直肠手术SSI的独立危险因素(均P＜0.05).结论 结直肠手术SSI存在多种危险因素,应重视并针对其危险因素制定干预措施,以降低SSI发生率.%Objective To explore risk factors for surgical site infection(SSI) in colorectal surgery,and provide evidence for formulating measures for preventing SSI.Methods Patients who underwent colorectal surgery in the department of gastrointestinal surgery of a hospital from June 2013 to June 2016 were surveyed retrospectively,the related risk factors for SSI were analyzed by unconditional logistic regression analysis.Results Among 397 patients who underwent colorectal surgery,67 (16.88％) had SSI.Logistic regression analysis showed that smoking,low albumin,seniority of surgeons less than 5 years,irrational use of antimicrobial agents during perioperative period,and high National Nosocomial Infection Surveillance (NNIS) score were independent risk factors for SSI after colorectal surgery (all P＜0.05).Conclusion There are multiple risk factors for SSI after colorectal surgery,it is necessary to pay attention to it and formulate preventive measures,so as to reduce the occurrence of SSI effectively.
