Treatment of cardiogenic shock with vasodilator drugs has been advocated on the basis of experimental work showing that a fall in peripheral resistance allows the cardiac output to increase without any increase in cardiac work.Seven patients suffering from shock secondary to myocardial infarction were treated with phenoxybenzamine. In two cases there was dramatic improvement in the signs and symptoms of shock, but in six of the seven cases there were severe adverse effects on respiration, including the development of wheezing and rales and rhonchi.
基于实验研究结果,有人主张使用血管扩张药物治疗心源性休克,这些研究表明外周阻力下降可使心输出量增加,而心脏做功并无增加。七名继发于心肌梗死的休克患者接受了苯氧苄胺治疗。其中两例休克的体征和症状有显著改善,但七例中有六例出现了严重的呼吸不良反应,包括喘息、啰音和哮鸣音。
