冠状动脉旁路移植术切口感染与非感染病例的对比分析

Infection and Non-infection on Incision of Coronary Artery Bypass Grafting:A Comparative Analysis

目的探讨冠状动脉旁路移植术(CABG)切口感染发生的原因与控制措施。方法以40例CABG切口感染病例为感染组及40例非感染病例为对照组,应用统计学秩和检验的方法,对两样本进行统计及对比分析。结果感染组的住院天数和各项医疗费用均大于对照组,感染组住院时间平均比对照组增加43.03 d(2.85倍),住院总费用平均增加人民币84 314.38元(2.02倍),差异有统计学意义。结论CABG手术切口感染的风险除患者因素以外,还来自很多患者以外的因素;要不断改进外科医师手术技巧,缩短患者术前住院日,更合理地预防使用抗菌药物;加强围手术期各相关环节的管理。

OBJECTIVE To discuss the cause of CABG infection and its controlling methodology. METHODS In order to conduct comparative analysis of 40 cases of CABG incision infection and 40 cases of CABG without infection, the ＂rank sum test＂ statistical models were applied. RESULTS According to the analysis of statistics, the hospitalized days and costs in sample group with infection were higher than that of control group, and the difference had statistical significance. Compared with the control group, the hospitalized days of sample group with infection averagely increased 43. 03 days （2. 85 times）, and the total hospitalized costs of it averagely increased RMB 84 314. 38 yuan （2.02 times）. CONCLUSIONS Apart from patients themselves, there are also many possibilities which will cause the infection, which ＇request the on-going works on surgery skills improvement, standardizing the process of aseptic technique, disinfection and isolation, utilizing antimicrobial agents rationally, reducing patients＇ hospitalized days before surgery, as well as improving the pre-operative management etc.
