心脏手术后切口感染危险因素及防控措施

Risk Factors and Prevention and Control Measures of Incision Infection After Cardiac Surgery

目的探讨心脏手术后切口病原菌分布及切口感染的危险因素,为切口感染的防控提供依据。方法回顾性分析2018年1月至2021年5月心脏手术后切口感染临床资料,对心脏术后切口感染的病原菌分布特点、切口感染发生的危险因素进行分析。结果406例心脏手术患者中,术后切口感染患者32例,感染率为7.88%;切口感染的单因素及多因素分析结果显示,胸带使用时间>3 d、糖尿病、术中输血是切口感染发生的独立危险因素(P<0.05)。结论心脏术后切口感染主要以金黄色葡萄球菌为主,切口感染发生的独立危险因素有胸带使用时间>3 d、糖尿病、术中输血。

Objective To investigate the distribution of pathogenic bacteria in incisions after cardiac surgery and the risk factors of incision infection,so as to provide evidence for the prevention and control of incision infection.Methods The clinical data of incision infection after cardiac surgery from January 2018 to May 2021 were retrospectively analyzed.The distribution characteristics of pathogenic bacteria and risk factors of incisional infection after cardiac surgery were analyzed.Results There were 406 patients undergoing cardiac surgery,including 32 patients with postoperative incision infection,and the infection rate was 7.88%.The univariate and multivariate analysis of incision infection showed that chest strap use time>3 days,diabetes and intraoperative blood transfusion were independent risk factors for incision infection(P<0.05).Conclusion Staphylococcus aureus is the main cause of incision infection after cardiac surgery.The independent risk factors for incision infection are chest strap use time>3 days,diabetes and intraoperative blood transfusion.
