Objective To analyze risk factors for surgical site infection(SSI) in cardiac surgery patients,so as to provide basis for making control measures.Methods 215 patients who underwent cardiac surgery in a hospital between January 2012 to December 2014 were investigated,univariate analysis and multivariate logistic regression analysis were used to analyze the related risk factors for postoperative SSI.Results The incidence of postoperative SSI in cardiac surgery patients was 16.28％ (35/215).Univariate analysis showed that the incidence of postoperative SSI was relatively higher in patients aged＞65 years,duration of operation＞5 hours,continuous operation,preoperative hospitalization time ＞7 days,irrational perioperative antimicrobial use,as well as patients with underlying diseases such as hypertension and diabetes mellitus.Multivariate logistic regression analysis indicated that the age,duration of operation,continuous operation,preoperative hospitalization time,irrational perioperative use of antimicrobial agents,and patients with underlying diseases were independent risk factors for SSI in patients who underwent cardiac surgery.Conclusion Incidence of SSI is higher in patients with cardiac surgery,preventive measures should be taken to control risk factors such as duration of operation,so as to reduce the incidence of SSI.%目的 探讨心脏外科患者手术部位感染危险因素,为制定控制措施提供依据.方法 选择2012年1月-2014年12月某院心脏外科收治的215例心脏手术患者,对可能引起手术部位感染的危险因素进行单因素及多因素分析.结果 心脏外科患者术后手术部位感染发病率为16.28％(35/215).单因素分析结果显示,年龄＞65岁、手术时间＞5 h、接台手术、术前住院时间＞7 d、围手术期抗菌药物使用不合理、患有高血压及糖尿病等基础疾病的患者手术部位感染发病率较高.多因素回归分析结果显示,年龄、手术时间、接台手术、术前住院时间、围手术期抗菌药物使用不合理、患基础疾病是心脏手术部位感染的独立危险因素.结论 心脏外科患者手术部位感染的发病率较高,应针对手术时间等可控因素采取防控措施,减少手术部位感染.
