食管癌术后心房颤动的高危因素分析

Predictors of atrial fibrillation following esophageal carcinoma surgery

目的 了解食管癌手术后心房颤动的发生率、高危因素及预防措施。方法 将 4 4例食管癌术后发生心房颤动的资料 (房颤组 ) ,与按 1∶5的比例从 6 6 2例术后未发生心房颤动的资料中随机抽取的 132例 (对照组 )做对照 ,观察两组年龄、性别、术前心肺功能、生化指标、术后并发症等对食管癌术后发生心房颤动的可能影响因素 ,并进行统计学处理。结果 食管癌术后心房颤动的发生率为 6 7% ,房颤组的年龄在 6 5岁以上和男性的比率明显高于对照组 (P <0 0 1) ,术前心肺功能异常及术后肺部感染的比率高于对照组 (P <0 0 1,P <0 0 5 )。结论 心房颤动是食管癌术后常见的心律失常之一 ,高龄、男性、术前心肺功能异常、术后肺部感染。

Objectiv In order to identify the incidence and clinical predictors of atrial fibrillation(Af)after esophageal carcinoma surgery and how to prevent it's occurrence.Methods 44 cases Af appeared compared with 132 cases randomly selected from 662 cases Af not appeared.Two groups's ages,sex,intraoperative cardiac function and pulmonary ventilation and postoperative complication were observed and were analysed with satistic methods.Results The overall incidence of postoperation Af was 6.7%.it is higher than that of gynecological surgery and nomal surgery.Af group's ages and the rate of above 65 was higher than that of control group(P<0 01),the rate of intraoperative cardiac function and pulmonary ventilation and postoperative pulmo infection was higher than that of control group(P<0 01,P<0 05).Conclusion Af remains the most common arrhythmia after esophageal carcinoma.Ages and intraoperative cardiac function and pulmonary ventilation and postoperative pulmo infection and the dirrect stimulation to heart by surgery can effect the incidence of Af.
