多巴酚丁胺是较新的人工合成儿茶酚胺类药物,具有强正性肌力作用,几乎没有变时性或致心律失常作用,其作用迅速且半寿期只有2～3分钟。本文旨在比较静脉注射多巴酚丁胺和地高辛在急性心肌梗塞24小时内发生心力衰竭病人中的血液动力学效应。
Dobutamine is a newer synthetic catecholaminergic drug with a strong positive inotropic effect with little or no time-variability or arrhythmogenic effects, with rapid action and a half-life of only 2-3 minutes. This article aims to compare the hemodynamic effects of intravenous injection of dobutamine and digoxin in patients with heart failure within 24 hours of acute myocardial infarction.
