有效循环血量的减少是休克的发病环节之一。近来有人报告,心源性休克时也有血容量低下的问题。根据动物实验说明,狗在急性心肌梗塞伴发休克时,血容量降低10％或20％。但血容量变化的原理尚不清楚。本工作测定了家兔实验性心源性休克时循环血量的变化,以便进一步研究心源性休克时循环血量的变化与其他因素的相互关系及其发病机理。 Reduction of effective circulating blood volume is one of the incidence of shock. Recently it was reported that cardiogenic shock also has the problem of hypovolemia. According to animal experiments show that dogs with acute myocardial infarction associated shock, the blood volume decreased by 10% or 20%. But the principle of blood volume changes is not clear. This study measured the changes of circulating blood volume in experimental cardiogenic shock in rabbits in order to further study the relationship between the changes of circulating blood volume and other factors during cardiogenic shock and its pathogenesis.
