Unlabelled: Data describing the use of extracorporeal membrane oxygenation (ECMO) in pediatric acute liver failure (PALF) are scarce. Thus, we aimed to describe the use of ECMO in patients with PALF using the data from the Extracorporeal Life Support Organization (ELSO) Registry between January 1, 2010, to December 31, 2022. We described patients' characteristics at ECMO initiation, outcome, and factors associated with mortality. A total of 335 children underwent ECMO support in the context of PALF. Veno-arterial (VA) ECMO was the most prevalent mode (66.6%), followed by veno-venous (VV) ECMO (33.4%). Extracorporeal cardiopulmonary resuscitation (ECPR) was used in 21.5% of the cardiac arrest. In-hospital mortality was 66.6%. Both higher lactate (OR 1.128, CI 1.06-1.209, p < 0.001) and PaCO2 (OR 1.022, CI 1.001-1.047, p 0.05) levels before ECMO reported greater odds of mortality. Low body weight, persistence of hyperlactatemia (OR 0.985, CI 0.973-0.997, p 0.013), and hyperbilirubinemia (OR 2.477, CI 1.042-6.100, p 0.045) after 24 h from ECMO deployment were associated to greater odds of mortality. Conclusions: Our results suggest that the use of ECMO for the management of respiratory and cardiac failure in patients with PALF should be considered with caution and that further research is needed to understand its role in this specific high-risk population. What is known: • Pediatric acute liver failure (PALF) is a clinical syndrome associated with significant morbidity and mortality. • Data on the use of extracorporeal membrane oxygenation (ECMO) in the context of PALF are scarce and controversial. What is new: • ECMO to manage acute respiratory and/or cardiac failure in the context of PALF should be considered with caution. • Bleeding and thrombotic complications in children with acute liver failure receiving ECMO are similar to the ones reported in the general pediatric population.

Abstract
Unlabelled: Data describing the use of extracorporeal membrane oxygenation (ECMO) in pediatric acute liver failure (PALF) are scarce. Thus, we aimed to describe the use of ECMO in patients with PALF using the data from the Extracorporeal Life Support Organization (ELSO) Registry between January 1, 2010, to December 31, 2022. We described patients' characteristics at ECMO initiation, outcome, and factors associated with mortality. A total of 335 children underwent ECMO support in the context of PALF. Veno-arterial (VA) ECMO was the most prevalent mode (66.6%), followed by veno-venous (VV) ECMO (33.4%). Extracorporeal cardiopulmonary resuscitation (ECPR) was used in 21.5% of the cardiac arrest. In-hospital mortality was 66.6%. Both higher lactate (OR 1.128, CI 1.06-1.209, p < 0.001) and PaCO2 (OR 1.022, CI 1.001-1.047, p 0.05) levels before ECMO reported greater odds of mortality. Low body weight, persistence of hyperlactatemia (OR 0.985, CI 0.973-0.997, p 0.013), and hyperbilirubinemia (OR 2.477, CI 1.042-6.100, p 0.045) after 24 h from ECMO deployment were associated to greater odds of mortality. Conclusions: Our results suggest that the use of ECMO for the management of respiratory and cardiac failure in patients with PALF should be considered with caution and that further research is needed to understand its role in this specific high-risk population.
