近十年来,二种因素的出现向麻醉医师提出了关心的新问题。其一是欣然愿意为有高度危险且有严重冠心病的外科患者作手术的外科同道们在不断增加。另一事实是关于患病和健全的左室功能的大量资料已经汇集,并被应用作指导心肌缺血的处理。这些知识被麻醉医师运用将使冠心病患者手术期间的发病率和死亡率减低。Mauney 和他的同事们把二年内有心肌梗塞的病人除外,发现在有心电图表现的冠心病病人中,有8%的病人术后发生心肌梗 In the past decade, the emergence of two factors has brought new concerns to anesthesiologists. One is the increasing willingness of surgical colleagues who are willing to operate on surgical patients with high-risk and serious coronary heart disease. Another fact is that a great deal of data on sick and sound left ventricular function has been pooled and used as a guide to guide the management of myocardial ischemia. This knowledge is used by anesthesiologists to reduce morbidity and mortality during coronary surgery. Mauney and colleagues excluded patients with myocardial infarction within two years and found that myocardial infarction occurred in 8% of patients with coronary artery disease who had electrocardiogram
