肝胆手术患者手术部位感染相关因素logistic回归分析

Univariate and multivariate factor logistic regression analysis on surgical site infection after hepatic surgery

目的研究肝胆手术患者手术部位感染(SSI)的影响因素,为预防SSI的临床措施提供参考。方法选取2012年1月-2014年1月医院212例接受肝胆手术治疗患者的临床资料,回顾性分析其SSI发生率,并使用SPSS19.0统计软件对SSI进行单因素及多因素logistic模型分析。结果 212例肝胆手术患者SSI发生率为11.79%;单因素分析显示,住院时间、血清白蛋白、手术方式、手术持续时长、切口类型和长度、手术中出血量、术后引流管留置时间及术后并发症是SSI发生的相关因素,而logistic回归分析结果表明,术后出现脂肪液化和切口裂开等并发症,手术持续时长及术后引流管留置时间是其独立危险因素。结论肝胆手术患者发生SSI,应采取综合性的预防措施,避免多因素共同导致的SSI发生,才能有效降低其感染率,改善患者预后。

OBJECTIVE To study the risk factors for surgical site infections （SSI） in patients with hepatobiliary op‐erations ,so as to provide the clinical basis for preventing SSI .METHODS The completeclinical data of 212 patients who underwent the hepatobiliary surgery were retrospectively investigated ,and the related factors for hepatobili‐ary SSI were analyzed with univariate and multivariate factor logistic regression model by SPSS19 .0 .RESULTS The infection rate of SSI after hepatic surgery was 11 .79 % .Single factor analysis showed that time of hospitaliza‐tion ,serum albumin ,operation methods ,length of operation ,incision types and length ,amount of bleeding dur‐ing operations ,time of indwelling of drainage tube post‐operation and postoperative complications were related fac‐tors for SSI .Logistic regression analysis showed that complications such as fat liquefaction and disruption of wound , length of surgeries and postoperative indwelling of drainage tube were independent risk factors . CONCLUSION Comprehensive preventive measures should be taken to control SSI caused by multiple factors .Only in this way can we effectively reduce the infection rate and improve the prognosis of the patients .
