高原地区外科手术对病人心脏的影响

Influence of Surgical Operation on Patients' Hearts at High Altitude

目的探讨高原地区外科手术对病人心脏的影响。方法对156例手术病人常规进行术前、术中、术后心电监护。术中出现异常ECG,及时给予相应的治疗。结果ECG阳性检出率术前为25.4%、术中为68.7%、术后为13.1%。术中98例ECG异常,经相应治疗80例恢复正常。结论高原环境不会加重对手术病人的心肌损害。心电监护对防治手术病人无症状性心肌缺血及心律失常有重要临床意义。

Objective To discuss the influence of surgical operation on the patients＇ hearts at high altitude. Methods A total of 156 patients were enrolled into the study, and their electrocardiograms （ECG） were monitored respectively before, during and after surgical operation. Corresponding treatment was administered if abnormal ECG appeared during the operation. Results The positive rates of abnormal ECG before, during and after surgical operation were 25.4% , 68.7% and 13.1% , respectively. Among the 98 patients with abnormal ECG during the surgical operation, there were 80 ones whose ECG returned to normal via treatment. Conclusion There was no additional damage in the cardiac muscle of the patients who were performed surgical operation under the condition of high altitude. Monitoring ECG is of importance for preventing the patients from asymptomatic cardiac ischemia and arrhythmia.
