Veno–veno–arterial extracorporeal membrane oxygenation …
网页2016年2月10日 · Veno–veno–arterial (VVA) ECMO may offer effective oxygenation and hemodynamic support without differential hypoxia by regulating the return of oxygenated blood to the underperfused coronary and cerebral circulation [3–5]. Therefore, VVA mode can be an alternative treatment modality for ARDS patients with severe septic shock.
Risk of harlequin syndrome during bi-femoral peripheral VA …
网页2020年7月20日 · The main finding of their simulation study was that arterial saturations are highly dependent on the venous cannulation site during VA-ECMO in patients with severe respiratory failure . Venous drainage from the superior caval vein is preferred in VA-ECMO if hypoxic respiratory failure is present .
The ELSO Maastricht Treaty for ECLS Nomenclature: abbreviations …
网页2019年2月8日 · Thus, “VVA” or “VAV” may be used in the same center for VA ECMO with dual return cannulae, depending on whether the initial mode was VV or VA . Separately, smaller catheters may be placed to promote distal perfusion of a cannulated lower extremity, e.g., on the arterial side [ 11 , 12 ], or to improve drainage or release congestion of ...
Disrupting differential hypoxia in peripheral veno-arterial ...
网页2015年12月1日 · Patients receiving circulatory support with peripheral veno-arterial extracorporeal membrane oxygenation (VA-ECMO) are at risk of developing differential hypoxia. This phenomenon occurs in patients with concomitant respiratory failure. Poorly oxygenated blood, ejected into the ascending aorta from the left ventricle, competes with …
Effects of different VV ECMO blood flow rates on lung perfusion ...
网页2024年8月17日 · Objective Our study aimed to investigate the effects of different extracorporeal membrane oxygenation (ECMO) blood flow rates on lung perfusion assessment using the saline bolus-based electrical impedance tomography (EIT) technique in patients on veno-venous (VV) ECMO. Methods In this single-centered prospective …
How I manage differential gas exchange in peripheral venoarterial ...
网页2023年10月27日 · Dual circulation is a common but underrecognized physiological occurrence associated with peripheral venoarterial extracorporeal membrane oxygenation (ECMO). Competitive flow will develop between blood ejected from the heart and blood travelling retrograde within the aorta from the ECMO reinfusion cannula. The intersection …
Comparison of anticoagulation strategies for veno-venous ECMO …
网页2021年1月4日 · Background Extracorporeal membrane oxygenation (ECMO) support in acute respiratory failure may be lifesaving, but bleeding and thromboembolic complications are common. The optimal anticoagulation strategy balancing these factors remains to be determined. This retrospective study compared two institutional anticoagulation …
Life-threatening massive pulmonary embolism rescued by …
网页2017年3月28日 · Background Despite quick implementation of reperfusion therapies, a few patients with high-risk, acute, massive, pulmonary embolism (PE) remain highly hemodynamically unstable. Others have absolute contraindication to receive reperfusion therapies. Venoarterial-extracorporeal membrane oxygenation (VA-ECMO) might lower …
Veno-venous ECMO indications: more than respiratory support
网页2019年8月7日 · Recently, we have read with tremendous interest the article published by Prof. Gattinoni et al. [1], which is focused on certain aspects that are under-evaluated in extracorporeal gas exchange therapy. Obviously, veno-venous extracorporeal membrane oxygenation (VV ECMO) indications are related to respiratory syndromes, and …
Optimizing PO2 during peripheral veno-arterial ECMO: a narrative …
网页2022年7月26日 · During refractory cardiogenic shock and cardiac arrest, veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is used to restore a circulatory output. However, it also impacts significantly arterial oxygenation. Recent guidelines of the Extracorporeal Life Support Organization (ELSO) recommend targeting postoxygenator …
