Prone positioning under VV-ECMO in SARS-CoV-2-induced acute respiratory distress syndrome

Background Infection due to severe acute respiratory coronavirus 2 (SARS-CoV-2) may lead to an atypical acute respiratory distress syndrome (ARDS) [1], requiring in the most severe cases veno-venous extracorporeal membrane oxygenation (VV-ECMO). [...]postmortem biopsies, performed in 6 patients with ECL in the prone ECMO group, found a fibrin exudative presence both in the alveolar spaces and bronchioles followed by a fibroblastic phase [5] and raise the question of the use of corticosteroids (only one patient in the prone ECMO group). [...]as already described by Zeng et al.
