近两年来,我院应用血管扩张剂酚妥拉明和消心痛治疗心力衰竭100例,疗效满意,现将临床观察情况报告如下: 一、机理酚妥拉明主要是扩大血管减少阻力;消心痛主要是扩大血管容量。从而降低心脏的前后负荷,最终使心排血量增加。酚妥拉明还有增加心肌收缩力的作用,而不增加心肌耗氧量,故用于治疗急性心肌梗塞合并泵衰更为适宜。 In the past two years, our hospital application of vasodilator vasopressin and Xiao Xiao Tong of heart failure treatment of 100 cases, the effect is satisfactory, the clinical observation is now reported as follows: First, the mechanism of Phentolamine is mainly to expand the vascular resistance to reduce; Is to expand the vascular capacity. Thus reducing the heart before and after the load, the final increase in cardiac output. Phentolamine also increase the role of myocardial contractility, without increasing myocardial oxygen consumption, it is used for the treatment of acute myocardial infarction with pump failure is more appropriate.
