关于休克的定义目前有三种看法: 一、休克是外周循环衰竭引起的。它是由于外周小动脉收缩致心脏输出量减少或外周小动脉扩张致有效循环量骤减,引起血压下降。这种说法虽能说明诸如感染性休克、出血性休克、过敏性休克等的临床现象,但不很全面,没有明确提出组织灌流量的问题,而且忽视了心脏在休克的作用,也不能圆满地解释心原性休克。 There are three current definitions of shock: First, shock is caused by peripheral circulatory failure. It is due to contraction of the peripheral arterioles resulting in reduced cardiac output or peripheral arteriolar expansion caused by the effective circulation abrupt decrease in blood pressure. Although this statement can explain such as septic shock, hemorrhagic shock, anaphylactic shock and other clinical phenomena, but not very comprehensive, did not explicitly put forward the issue of tissue perfusion, but also ignored the role of the heart in shock can not be satisfactorily Explain cardiogenic shock.
