【摘要】 目的 分析总结引起体外循环下停跳冠状动脉搭桥(CABG)围术期死亡的危险因素。方法 2000年4月～2004年4月施行的单纯CABG病人229例，对比性别、年龄、高血压、糖尿病、脑血管意外、肺部疾病史、肾功能、术前心梗、心衰、心功能分级以及造影情况、CPB时间、阻断时间、搭桥数、低心排、心律失常、心衰、IABP辅助、低血压、少尿、大量引流、开胸止血、肺部感染、呼衰、肾衰、纵隔感染、下肢感染、清创、消化道出血等因素，采用Logistic回归法寻找危险因素。结果 回归法显示术后使用IABP、脑梗死、长时间转流、急性肾功能衰竭和术前NYHA分级是围术期死亡的危险因素。结论 各项危险因素需进一步细化分析，以更好地降低死亡率。

    【Abstract】 Objective To find out the risk factors of peri-operative mortality of CABG.Methods Two hundreds and twenty-nine patients underwent isolated on-pump CABG from 2000 to 2004.The selected factors are:gender,age,hypertension,diabetes,previous cerebrovascular accident,COPD,renal dysfunction,previous heart attack,chronic heart failure,NYHA grade,vascular angiogram,CPB time,Cross-clamp time,number of bypassed vessels,all kinds of peri-operative complication.Using Logistic analysis to find out the risk fators.Results Using IABP,brain embolism,elongated CPB time and NYHA grade are the risk factors of peri-operative death.Conclusion We need to do more details to decrease the mortality. ......
