63例肝胆手术部位感染相关因素分析

目的：对肝胆手术部位感染相关影响因素进行探讨。方法回顾性分析1187例肝胆手术患者的临床资料，采用SPSS12．0软件对数据进行统计分析。结果1187例肝胆手术患者发生手术部位感染63例，感染率5．31％，其中切口浅部组织51例，切口深部组织8例，器官腔隙4例，分别占80．95％、12．70％和6．35％。分离出革兰阴性菌15株，占55．56％，革兰阳性菌12株，占44．44％，其中革兰阴性菌以大肠埃希菌、革兰阳性菌以金黄色葡萄球菌检出最多，分别占25．93％和14．81％，未分离出真菌；年龄、有无合并糖尿病、引流时间、术后并发症、手术时间和开腹手术等为手术部位感染的独立危险因素（P ＜0．05）。结论肝胆外科患者手术部位感染与多种因素有关，应加强患者术前术后病情评估，同时提高手术操作水平，从而降低手术部位感染率。

63 cases of liver surgical site infection related factors analysis

Objective To liver surgical site infection related influencing factors were discussed.Methods Retrospective analysis the clinical data of A total of 1 187 patients with liver and gallbladder surgery,using SPSS12.0 software for statistical analysis of data.Results A total of 1 187 cases of liver and gallbladder surgery patients and 63 cases of surgical site infection occurred,the in-fection rate of 5.31%,including incision shallow tissue 51 cases,8 incision deep tissue,organ lacuna in 4 cases,accounted for 80.95%,12.70% and 6.35% respectively.Isolated pathogenic bacteria distribution and composition ratios were as follow,15 strains of gram-negative bacteria(55.56%),12 gram positive bacteria strains(44.44%),including gram-negative bacteria in e.coli, gram-positive bacterium with staphylococcus aureus detection most(25.93% and 14.81% respectively),not isolated fungus;Age, presence of diabetes mellitus,drainage time,postoperative complications,operation time and open operation for independent risk fac-tors for surgical site infection (P <0.05).Conclusion Liver and gallbladder surgery in patients with surgical site infection is asso-ciated with a variety of factors,should strengthen the preoperative patients with postoperative condition evaluation,improve the lev-el of operation at the same time,thereby reducing surgical site infection.
