一、概念 休克(Shokc)是个临床急症,不同病因的休克有其不同的概念,但不论那种休克其共同的病理生理改变都是有效循环血量锐减,身体组织血液灌注不足所引起的微循环障碍,从而导致组织细胞缺血、缺氧、酸中毒、电介质紊乱、血管内积血甚至组织坏死、细胞组织脏器功能、代谢、信使、循环等发生一系列的复杂变化。休克的发生阶段不同,其病理生理改变也不同,血压下降虽可为休克的病因,而重要的是休克的结果。休克早期并非血压下降,血压降低是休克的血流动力学障碍表现,任何休克都将有血压下降,反之,血压下降不一定都是休克。
First, the concept of shock (Shokc) is a clinical emergency, shock of different causes have different concepts, but regardless of the shock of their common pathophysiological changes are effective blood volume decreased sharply, the body caused by inadequate blood perfusion Circulatory disorders, resulting in a series of complex changes in tissue cells such as ischemia, hypoxia, acidosis, dielectric disturbance, intravascular hemorrhage and even tissue necrosis, cell and organ function, metabolism, messenger and circulation. Shock stage of occurrence of different pathophysiological changes are also different, although the decline in blood pressure may be the cause of shock, but important is the result of shock. Shock is not early blood pressure, blood pressure is decreased hemodynamic shock performance, any shock will have blood pressure, on the contrary, blood pressure drops are not necessarily all shock.
