休克是临床上常见的综合征,按照病理生理学改变主要分为4种类型,包括心源性休克、低血容量性休克、梗阻性休克和分布性休克。各种类型休克的核心均为微循环灌注不足,造成组织氧供和氧交换受到影响,导致组织细胞缺氧,引起组织器官功能障碍。休克类型中的分布性休克(如脓毒症休克)最为复杂。临床上常见的脓毒症休克患者的心排出量可以正常甚至高于正常,周围血管阻力也可能正 Shock is a clinically common syndrome, according to the pathophysiology of change is divided into four types, including cardiogenic shock, hypovolemic shock, obstructive shock and distributive shock. Various types of shock are the core of microcirculation perfusion, resulting in tissue oxygen supply and oxygen exchange are affected, leading to tissue cells hypoxia, causing organ dysfunction. Shock in the distribution of shock (such as septic shock) the most complex. Cardiac excretion in patients with septic shock can be normal or even higher than normal, peripheral vascular resistance may also be positive
