L’entrée en scène

« La plupart des artistes de théâtre, et beaucoup de metteurs en scène en premier lieu, reconnaissent que l’entrée en scène, ses modalités, sa dramaturgie, est un acte décisif : il engage tout le spectacle à venir, il détermine sa réception, il éveille la sensibilité du spectateur, et conditionne donc son intelligence. » Jean-Loup Rivière, Entrée libr

Veno-Arterial Extracorporeal Membrane Oxygenation for Circulatory Failure in COVID-19 Patients: Insights from the ECMOSARS Registry

International audienceObjectives: The clinical profile and outcomes of patients with Covid-19 who require veno-arterial or veno-venous-arterial extracorporeal membrane oxygenation (VA-ECMO - VAV-ECMO) are poorly understood. We aimed to describe the characteristics and outcomes of these patients and to identify predictors of both favorable and unfavorable outcomes.Methods: ECMOSARS is a multicenter, prospective, nationwide French registry enrolling patients who require VV/VA-ECMO in the context of Covid-19 infection (652 patients at 41 centers). We focused on 47 patients supported with VA- or VAV-ECMO for refractory cardiogenic shock.Results: Median age was 49. 14% of patients had a prior diagnosis of heart failure. The most common etiologies of cardiogenic shock were acute pulmonary embolism (30%), myocarditis (28%), and acute coronary syndrome (4%). E-CPR (Extracorporeal Cardiopulmonary Resuscitation) occurred in 38%. In-hospital survival was 28% in the whole cohort, and 43% when E-CPR patients were excluded. ECMO cannulation was associated with significant improvements in pH and FiO2 on day one, but non-survivors showed significantly more severe acidosis and higher FiO2 than survivors at this point (p = 0.030 and p = 0.006). Other factors associated with death were greater age (p = 0.02), higher BMI (p = 0.03), E-CPR (p = 0.001), non-myocarditis etiology (p = 0.02), higher serum lactates (p = 0.004), epinephrine (but not noradrenaline) use before initiation of ECMO (p = 0.003), hemorrhagic complications (p = 0.001), greater transfusion requirements (p = 0.001), and more severe SAVE and SAFE scores (p = 0.01 and p = 0.03).Conclusions: We report the largest focused analysis of VA- and VAV-ECMO recipients in Covid-19. Although relatively rare, the need for temporary mechanical circulatory support in these patients is associated with poor prognosis. However, VA-ECMO remains a viable solution to rescue carefully selected patients. We identified factors associated with poor prognosis and suggest that E-CPR is not a reasonable indication for VA-ECMO in this population
