柳丁氨醇(Sulbutamol)是一种β_2-肾上腺素能兴奋剂,能使平滑肌松弛和降低体循环血管阻力。晚近,Sharma 等报道充血性心肌病患者静脉注射柳丁氨醇具有良好疗效,认为其主要作用犹如正性收缩能制剂。本文旨在研究慢性充血性心力衰竭患者口服和静脉注射柳丁氨醇后的血液动力学效应,并探求本药的作用究系血管扩张还是增加心肌收缩力。方法:甲组11例给柳丁氨醇8毫克口服,其中 Sulbutamol is a beta 2 -adrenergic stimulant that relaxes the smooth muscle and reduces systemic vascular resistance. Recently, Sharma et al reported that intravenous injection of salbutamol in patients with congestive cardiomyopathy has good efficacy, and that its main role is like a positive systolic agent. This article aims to study the hemodynamic effects of oral and intravenous salbutamol in patients with chronic congestive heart failure and to explore the role of this drug in studying whether vasodilation or increased myocardial contractility. Methods: A group of 11 cases to salbutamol 8 mg orally, of which
