腹部外科患者手术部位感染危险因素分析

Risk factors for surgical site infections in patients undergoing abdominal surgery

目的分析发生腹腔手术后切口感染的高危因素,并探讨相关预防措施,为临床治疗提供数据依据。方法选取2011年1月-2013年2月在医院普通外科病房住院并行腹部手术的883例患者,将术后发生手术部位感染(SSI)30例患者分为感染组,未发生SSI 583例患者分为非感染组,研究其术后SSI发生率,对可能影响SSI的因素先进行单因素分析后,再进行非条件losistic多因素回归分析。结果 883例患者术后发生手术部位感染30例,感染率为3.4%;单因素分析发现10个与SSI有关的因素,losistic多因素回归分析发现年龄大、BMI指数高、手术时间长、合并基础疾病、急诊手术、Ⅱ、Ⅲ类切口是发生SSI独立危险因素。结论腹部外科患者术后手术部位感染率高,与患者自身及手术方面的多个因素相关,应针对相关危险因素预防与控制手术部位感染。

OBJECTIVE To analysis the risk factors of infection after abdominal surgery and to explore related preventive measures ,in order to provide data basis for clinical treatment .METHODS The data of 883 general surgical patients hospitalized from Jan .2011 to Feb .2013 were analyzed retrospectively and were divided into two groups .The 30 cases of patients of surgical site infection （SSI） were treated as infection group and the other 583 cases as non-infection group ,and the factors that might cause surgical site infection were analyzed by single-factor and logistic regression .RESULTS From 883 cases ,30 cases were with incision infection .The surgical site infec-tion rate was 3 .4% .There were 10 factors related to SSI by single-factor analysis ,older age ,higher BMI ,long surgery time ,combined with underlying diseases ,emergent surgery and Ⅱ/Ⅲ incision were found as the related factors causing surgical site infection by logistic regression analysis . CONCLUSION Patients with abdominal surgery have high postoperative surgical site infection rate ,and it is associated with a number of the patients and surgical aspects factors .We should focus on risk factors associated with the prevention and control of surgical site infection .
