在心脏病人麻醉管理时,心电图、直接动脉压的监测已成常规。当前留置 Swan-Ganz 导管也成为常用的方法,这些方法能准确提供相应的情况,是麻醉管理中必不可少的监测手段。在缺血性心脏病人麻醉管理中,最重要的是防止已缺氧的心肌增加心肌氧耗量,然而目前尚不能在临床测定心肌氧消耗量(MVO_2)。尽管也有冠状静脉窦插管及超声心动图等测定方法,但目前还不能作为日常手段,因此只得依赖间接的 MVO_2指标。心率—压力乘积 RPP 作为间接 MVO_2指标之一面被重视。Kaplan 等对冠状动脉疾病病人麻醉中观察到 RPP 在12,000以上者心电图均有缺血改变,无缺血
In the management of cardiac patients anesthesia, ECG, direct arterial pressure monitoring has become routine. Current indwelling Swan-Ganz catheters have also become common methods that can accurately provide the appropriate conditions and are an essential monitoring tool in anesthesia management. In the management of ischemic heart diseases, the most important thing is to prevent myocardial hypoxia from increasing myocardial oxygen consumption. However, myocardial oxygen consumption (MVO2) can not be measured clinically at present. Although coronary sinus catheterization and echocardiography and other measurement methods, but not as a daily means, it has to rely on indirect MVO_2 indicators. The heart rate-pressure product RPP is taken as one of the indirect MVO_2 indicators. Kaplan and other patients with coronary artery disease observed in the RPP more than 12,000 were ischemic ECG changes, no ischemia
