Veno–veno–arterial extracorporeal membrane oxygenation …
2016年2月10日 · Eight patients with severe acute respiratory distress syndrome and septic shock received veno–veno–arterial extracorporeal membrane oxygenation (VVA ECMO) support. VVA ECMO improved hemodynamics, oxygenation, and survival in most patients, but the sample size was small and the study was retrospective.
How I manage differential gas exchange in peripheral venoarterial ...
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 of these two competitive …
The ELSO Maastricht Treaty for ECLS Nomenclature: abbreviations …
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 ...
Comparison of anticoagulation strategies for veno-venous ECMO …
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 management strategies …
Disrupting differential hypoxia in peripheral veno-arterial ...
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 retrograde flow from the …
Risk of harlequin syndrome during bi-femoral peripheral VA …
2020年7月20日 · A letter to the editor discusses the risk of harlequin syndrome, a differential hypoxia in upper and lower body, during peripheral veno-arterial extracorporeal membrane oxygenation (VA-ECMO). The authors suggest that changing the venous cannulation site from inferior to superior caval vein may improve upper body oxygenation, and contrast-enhanced …
Duration of veno-arterial extracorporeal life support (VA ECMO) …
2017年3月6日 · Background Veno-arterial extracorporeal membrane oxygenation (VA ECMO) is an effective rescue therapy for severe cardiorespiratory failure, but morbidity and mortality are high. We hypothesised that survival decreases with longer VA ECMO treatment. We examined the Extracorporeal Life Support Organization (ELSO) registry for a relationship between VA …
Veno-venous ECMO indications: more than respiratory support
2019年8月7日 · Obviously, veno-venous extracorporeal membrane oxygenation (VV ECMO) indications are related to respiratory syndromes, and traditionally, its indication criteria were limited to gas exchange and respiratory mechanics. However, we consider that VV ECMO indications should not be limited to these.
Parameters associated with successful weaning of veno-arterial ...
2022年12月5日 · Purpose Veno-arterial (VA) extracorporeal membrane oxygenation (ECMO) can be used to restore organ perfusion in patients with cardiogenic shock until native heart recovery occurs. It may be challenging, however, to determine when patients can be weaned successfully from ECMO—surviving without requiring further mechanical support or heart transplant. We …
Optimizing PO2 during peripheral veno-arterial ECMO: a narrative …
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 partial pressure of …
