心原性休克是指原发性心脏泵功能衰竭和继发性周围器官组织灌注衰竭互为因果恶性循环所造成的休克综合征。目前国外普遍采用美国心脏病研究所的诊断标准:1.动脉压<90mmHg或比原有基础降低30mmHg。2.循环血量减少的证据;(1)尿量减少,常<30ml/h,(2)神志障碍(意识模糊、嗜睡、昏迷),(3) 周围血管收缩伴四肢厥冷、冷汗、皮肤凉湿、发绀等末梢循环衰竭征象。3.纠正引起心输出量减少和血压降低的因素如低血容量、心律失常、低氧等后,休克依然存在。一、血流动力学监测的重要性: 心原性休克的血流动力学变化,主要有三:①心
Cardigenic shock refers to the shock syndrome caused by a vicious circle of causal cycles between primary cardiac pump failure and secondary perfusion of peripheral organ tissue. At present, foreign countries generally use the diagnostic criteria of the American Heart Institute: 1. Arterial pressure <90mmHg or lower than the original 30mmHg. (2) delirium (confusion, drowsiness, coma), (3) peripheral vasoconstriction with extremities and cold, cold sweat, skin Cold and wet, cyanosis and other signs of peripheral circulation failure. 3. To correct the causes of cardiac output and reduce blood pressure caused by factors such as hypovolemia, arrhythmia, hypoxia, shock still exists. First, the importance of hemodynamic monitoring: hemodynamic changes in cardiogenic shock, there are three: ① heart
