冠心病病人非心脏手术后心肌缺血原因分析

Causative Analysis on Postoperative Myocardial Ischemia in Coronary Heart Disease Patients Underwent Non-cardiac Surgery

目的 :为探讨冠心病病人术后麻醉苏醒期发生心肌缺血加重的原因及临床表现特点。方法 :对16 3例冠心病病人术后进行持续血压、脉搏血氧饱和度 (SPO2 )、肛温、心电监护、中心静脉压 (CVP)监测 ,观察心电图ST -T变化。结果 :发现术后低温、低氧血症、心动过速、血压异常可引起ST -T改变。结论 :冠心病病人术后出现心肌缺血 ,甚至心肌梗死可无临床症状 ,提示应加强监护 ,及时发现各种危险因素 ,防止心脏严重并发症的发生。

Objective: to probe into the causes and clinical manifestation of myocardial ischemia exacerbation in de-anesthesia stage of postoperative patients with coronary heart disease underwent non-cardiac surgery. Method: a total of 163 cases of postoperative coronary heart disease patients were carried out monitoring on their blood pressure, pulses, blood oxygen saturation (SPO 2), anal temperature, electrocardiogram (ECG), and central venous pressure (CVP). The ST-T changes in ECG of patients were observed. Results: it was found that postoperative hypothermia, hypoxemia, tachycardia, and abnormality of blood pressure of patients may cause their ST-T changes in ECG. Conclusion: coronary heart disease patients developed postoperative myocardial ischemia even myocardial infarction may be asymptomatic. It suggested that one should strengthen the monitoring and find out all sorts of risk factors of patients to prevent their cardiac complications from happening.
