超滤是心力衰竭的一种可选择的治疗方法,可以减少右心房压和肺动脉楔压,增加心输出量,并产生利尿作用和增加尿钠排出,而不影响患者的心率、收缩压、肾功能、电解质以及血管内容量。研究表明,通过外周血管进行超滤治疗对于容量超负荷的心衰患者是安全和有效的。本文主要介绍超滤在心力衰竭治疗中的原理、应用和研究现状。 Ultrafiltration is an alternative treatment of heart failure, can reduce the right atrial pressure and pulmonary wedge pressure, increase cardiac output, and produce diuretic effects and increased urinary sodium excretion, without affecting the patient’s heart rate, systolic blood pressure, kidney Function, electrolyte and intravascular volume. Research shows that ultrafiltration through peripheral blood vessels is safe and effective for patients with volume overload heart failure. This article describes the principle of ultrafiltration in the treatment of heart failure, application and research status quo.
