食管癌术后心律失常相关因素分析

Related Factors of Postoperative Arrhythmias in Esophageal Carcinoma Patients

为了探讨影响食管癌术后心律失常的相关因素,观察了术后心律失常的发生与患者年龄(≥65岁)、性别、吸烟、术前合并症、肺功能、心电图(EKG)改变、低血钾、术后24小时失血量及手术方式的关系。结果显示,318例食管癌术后心律失常发生率为47.48%。年龄(≥65岁)、FEV1/FVC≤70%和/或MVV%≤60%、术前ECG异常、术前血钾≤4.0mmol/L、术后24小时失血≥500ml及手术方式与术后心律失常的发生相关。提示术前改善低心肺功能、纠正低血钾、减少术中出血,高龄患者和多切口手术方式者术后加强监护,可预防和减少术后心律失常发生。

To explore the related factors of arrhythmia in postoperative esophageal carcinoma patients, we observe the relationship among arrhythmia and some factors such as age （ ≥ 65 years old ）, sex, smoking, preoperative cardiopulmonary complications, lung function, the change of electrocardiogram （EKG）, hypokalemia, blood loss after operation in 24 hours and operation method. Among 318 esophageal carcinoma patients, the incidence rate of postoperative arrhythmia is 47.48 %. The factors of postoperative arrhythmia include age（≥65 years old）, FEV1/FVC≤70 % and/or MVV%≤60 %, the change of preoperative EKG, hypokalemia less than 4.0 mmol/ L, blood loss≥500ml after operation in 24 hours and operation method. Therefore, prevent and decrease the occurrence of postoperative arrhythmia, it is necessary to improve preoperative cardiopulmonary function, treat hypokalemia, decrease blood loss and reinforce postoperative care to the older and patients with more incision.
