急性循环障碍(梗阻性休克)是急性巨大肺栓塞(AMPE)患者最重要的死亡原因。液体负荷试验是其它各类休克的首选治疗方法,但是否对AMPE导致的急性循环衰竭具有治疗作用一直存在争论。有学者认为液体负荷试验可以提高右心室前负荷,从而提高心输出量;而有些学者则认为液体负荷试验加重右心室壁缺血,同时因右心室舒张末期容积增加,使左心室充盈减少,减少心输出量,加重循环衰竭。作者通过观察 Acute circulatory disturbance (obstructive shock) is the most important cause of death in patients with acute giant pulmonary embolism (AMPE). Fluid stress testing is the preferred treatment for all other types of shock, but it remains controversial whether or not it has a therapeutic effect on AMPE-induced acute circulatory failure. Some scholars believe that liquid stress test can improve the right ventricular preload, thereby improving cardiac output; while some scholars believe that liquid stress test aggravates right ventricular wall ischemia, while the right ventricular end-diastolic volume increases, so that the left ventricular filling decreased and decreased Cardiac output, increased circulation failure.
