心力衰竭(下简称心衰)是儿科常见的危重急症之一,近年来由于心衰的病理生理、生物化学及洋地黄的药理动力学的研究,以及新的强效利尿剂,血管扩张剂的应用,使小儿心衰治愈率有了很大的提高。一、心衰的病理生理:充血性心衰时,血液排出量低于机体需要量,血液动力学的特点为心排出量减少,全身血管阻力增高,肺淤血,左室舒张终末
Heart failure (heart failure) is one of the most common critical emergency in pediatrics. In recent years, due to the pathophysiology of heart failure, biochemistry and the pharmacokinetics of digitalis, as well as the new potent diuretics, vasodilators Application, the cure rate of heart failure in children has been greatly improved. First, the pathophysiology of heart failure: congestive heart failure, the blood volume lower than the body needs, hemodynamic characteristics of reduced cardiac output, systemic vascular resistance increased, pulmonary congestion, left ventricular end diastolic
