Concept 【 Shock】 休克是指机体在受到各种有害因子作用后发生的,以 组织灌流量急剧降低为特征,并导致细胞功能、结构损伤 和各重要器官机能代谢紊乱的复杂的全身性病理过程。 Shock is a clinical condition and pathophysiologic process haracterized, regardless of cause, by inadequate blood flow to vital organs and inability of body cell mass to metabolize nutrients normally

【 Shock】 休克是多病因、多发病环节、多种体液因子参与的 种全身性病理过程,其始动环节是有效循环血量急剧 减少,其主要特征是微循环功能障碍,其后果是器官功 能衰竭
