目的分析1516例施行非体外循环冠状动脉旁路移植术(OPCABG)的男性患者术中心室颤动发生的危险因素.方法回顾性分析麻醉科2007年11月至2009年2月1516例记录齐全的男性患者OPCABG围术期资料.以术中发生心室颤动为因变量,将有统计学意义的单因素进行Logistic回归分析,并用Logistic回归分析模型评价各影响因素的作用大小.结果全组患者术中发生心室颤动24例(1.6％),无一例死亡.术前左心室射血分数(LVEF)＜ 40％(P＜0.01,OR=17.182)、搭桥数＞3支(P ＜0.05,OR=3.233)和术中发生心房颤动(P＜0.01,OR=24.979)为术中发生心室颤动的独立危险因素.结论患者术前左心室功能差(LVEF ＜40％)、冠状动脉搭桥支数大于3支和术中发生心房颤动与OPCABG手术中发生心室颤动密切相关.

Objective To analyze the risk factors of intraoperative ventricular fibrillation in male patients undergoing off-pump coronary artery bypass grafting (OPCABG).Methods The perioperative data of 1516 male patients undergoing OPCABG were investigated based on the perioperative OPCABG database from Nov.2007 to Feb.2009.The risk factors were identified by multiple logistic regression.Results 24 patients (1.6％) were suffered from intraoperative ventricular fibrillation and no patient died during OPCABG.Multivariate analysis demonstrated that preoperative ejection fraction (LVEF) less than 40％ (P ＜ 0.01,OR =17.182),more than 3 grafts (P ＜ 0.05,OR =3.233) and intraoperative atrial fibrillation (P ＜ 0.01,OR =24.979) were the independent risk factors of intraoperative ventricular fibrillation in male patients undergoing off-pump coronary artery bypass grafting.Conclusion This study shows LVEF less than 40％,more than 3 grafts and intraoperative atrial fibrillation are predominant factors of intraoperative ventricular fibrillation during OPCABG.
