AbstractWe report two female patients with adult respiratory distress syndrome and severe respiratory failure in whom extracorporeal membrane oxygenation was used. Its indication was due to a bad response to conventional treatment with mechanical ventilation and high levels of positive end expiratory pressure. A 2.0 or 2.2 m2 membrane oxygenator in a veno-venous circuit with systemic anticoagulation was used, maintaining mechanical ventilation. In the first patient, the procedure was done early and was successful, increasing hemoglobin saturation from 39 to 87%. The patient was withdrawn from the procedure 48 hours later and died one week later due to a septic shock. The second patient was connected to the procedure after three weeks of respiratory distress syndrome and no increase in arterial oxygenation was achieved. The patient died due to an intracranial hemorrhage, probably hastened by systemic anticoagulation. The real benefits of extracorporeal membrane oxygenation are not defined yet.
