三、解痉、去淤、给氧 (一)解痉、去淤:微动脉、小静脉的收缩痉挛及微循坏血流的淤滞,是造成休克一系列病理生理变异的重要环节。因此,及时解痉、去淤,疏通微循环,是治疗休克的重点。 1.及时适量扩容:具有改善血液动力、中断休克的恶性循环的作用,通过机体本身的调节,使过度的神经、内分泌反应恢复正常,使心排血量的异常分配消失,使内脏血液灌注量恢复到生理状态,改善微循环。如内脏尚未受到不可逆损害,原有代谢紊乱及缺氧细胞的释放分解物质,也就可靠机体本身的缓冲、代偿、解毒、消除等功能自行解决。 2.应用血管解痉药物:目的在于使微循环进
Third, antispasmodic, to silt, oxygen (a) antispasmodic, to silt: arterioles, venules contraction spasm and microcirculation of blood stasis, is caused by a series of pathophysiological shock an important part of the pathophysiology. Therefore, timely spasm, to silt, to clear the microcirculation, is the focus of the treatment of shock. 1. Timely volume expansion: with the improvement of hemodynamics, the role of the vicious cycle of interruption of the role of shock, through the body’s own regulation, so that excessive nerve and endocrine reactions returned to normal cardiac output anomalies disappear, so that visceral blood perfusion Restore to the physiological state, improve microcirculation. If the viscera has not been irreversibly damaged, the original metabolic disorders and hypoxic cells to release the decomposition of substances, it is also reliable body itself buffer, compensation, detoxification, elimination and other functions to solve. 2. Application of vasospasm drugs: the purpose is to make microcirculation
