2018年9月18日 · Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is a form of temporary mechanical circulatory support and simultaneous extracorporeal gas exchange for acute cardiorespiratory failure. 1, 2 All VA-ECMO circuits consist of a venous (inflow, drainage) cannula, a pump, an oxygenator, and an arterial (outflow, return) cannula.

Venoarterial (VA) ECMO provides support for the patient's heart and lungs by allowing most of a patient's blood to move through the circuit without going through the patient's heart. This type of ECMO takes blood out of a large vein and returns it into a large artery, allowing oxygen-rich blood to circulate through the body even if the heart is ...

2019年12月9日 · We provide a practical review for cardiovascular clinicians on the application of veno-arterial extracorporeal membrane oxygenation in adult patients with cardiogenic shock, including epidemiology of cardiogenic shock, indications, contraindications, and the extracorporeal membrane oxygenation circuit.

2024年10月6日 · Peripheral VA ECMO. back flow cannula used to prevent limb ischaemia; oxygenated blood returned to aorta so lungs get little O2 rich blood -> may exacerbate lung ischaemia; lower body receives better perfusion; Advantages. good Q; can create high oxygen tensions; Disadvantages. relative lung ischaemia; non-pulsatile blood flow

2022年7月11日 · 作为顽固心源性休克的挽救性治疗措施, VA-ECMO这一临时循环支持 (TCS) 技术在临床中应用越来越多。本文拟对VA-ECMO原理、适应症、管理、并发症作以综述, 并对最近发表的病例报告及试验研究结果予以讨论。 最近发现. VA-ECMO已广泛用于进一步临床决策的过渡, 这些临床决策包括: 心功能恢复后的ECMO撤机, 心脏移植, 长期机械循环支持装置的植入, 一旦治疗无望后的终止治疗。 VA-ECMO被认为是一线的TCS选择，是因为该措施可快速改善氧合、花费 …

Veno-venous (VV) or veno-arterial (VA) ECMO requires the drainage of deoxygenated blood from the venous system, moving it across a membrane oxygenator that removes carbon dioxide (CO 2), replenishes oxygen, and returns oxygenated blood back to the patient’s venous or arterial system depending on the use of VV or VA, respectively.

2025年1月15日 · VA ECMO increases LV afterload (which may impair LV function) and reduces RV preload. Weaning VA ECMO involves reducing ECMO support to determine how the heart will respond to increased RV preload and reduced LV afterload.

2020年10月1日 · Venoarterial extracorporeal membrane oxygenation (ECMO) is a well-established technique to rescue patients experiencing cardiogenic shock. As a form of temporary mechanical circulatory support, venoarterial ECMO can be life-saving, but it is resource intensive and associated with substantial morbidity and mortality.

2020年3月3日 · VENOARTERIAL extracorporeal membrane oxygenation (VA ECMO) is a form of mechanical circulatory support (MCS) intended to temporarily replace cardiopulmonary function in patients experiencing refractory cardiogenic shock.

V-A ECMO is used provide both circulatory and gas exchange support. It is considered in patients with severe cardiac failure or combined cardiac and respiratory failure refractory to inotropes, intra-aortic balloon counterpulsation and mechanical ventilation.
