摘　　要：目的分析心脏直视术后手术部位感染相关风险因素并在此基础上提出科学高效的解决策略,以降低心脏直视术后手术部位感染率。方法选取2012年3月-2015年3月于医院接受心脏直视手术治疗的患者258例为研究对象,采用回顾性调查方式分析病原菌构成及相关危险因素,数据采用SPSS 18.0软件进行统计分析。结果 258例心脏直视手术患者中有9例发生手术部位感染,感染率为3.49%;共检出14株病原菌,以革兰阴性菌为主,共7株,占50.00%;logistic回归分析结果显示,年龄、手术进行时间、手术过程失血量、抗菌药物的合理使用、外物置入等是导致患者术后手术部位感染发生的独立危险因素(P<0.05)。结论心脏直视手术术后手术部位感染的相关风险因素很多,需关注患者及手术操作等方面影响,提高手术治疗效果、降低手术部位感染率。OBJECTIVE To analyze the surgery-related risk factors of surgical site infections after open heart to provide scientific and efficient solution strategy,in order to reduce surgical site infection after open heart surgery.METHODS A total of 258 patients undergoing open heart surgery in the hospital from Mar.2012 to Mar.2015 were selected,using retrospective survey method to give a analysis of the constitute of pathogens and related risk factors.SPSS 18.0was used for data statistic analysis.RESULTS There were 9cases of surgical site infections in258 cases of open heart surgery,and the infection rate was 3.49%.A total of 14 strains of pathogens,mainly gram-negative bacteria 7strains,accounting for 50.00%.Logistic regression analysis showed that age,time of surgery,blood loss amount during surgery,rational use of antimicrobial drugs,and other foreign objects implantation were the independent risk factors for postoperative surgical site infections occurred in patients（P〈0.05）.CONCLUSIONThere are many risk factors associated with surgical site infections after open heart surgery.Both patients and surgical procedures should be paid enough attention to improve surgical outcomes and reduce surgical site infection rates.
