Early initiation of venovenous extracorporeal membrane oxygenation in a mechanically ventilated patient with severe acute respiratory distress syndrome

Abstract

A 49-year-old man presented to the emergency department with acute-onset dyspnoea and hypoxaemia 1 day following nasal surgery for obstructive sleep apnoea. A chest X-ray showed diffuse bilateral pulmonary infiltrates. Supplemental 100% fractional inspired oxygen (FiO2) via non-rebreather mask was delivered with resulting arterial oxygen tension:FiO2 ratio of 67. Transthoracic echocardiogram demonstrated normal heart function. A clinical diagnosis of severe acute respiratory distress syndrome (ARDS) was promptly made. Based on patient preference to avoid intubation and following a multidisciplinary approach, we decided to initiate venovenous extracorporeal membrane oxygenation (VV-ECMO) as an alternative strategy to mechanical ventilation. Though he ultimately required brief mechanical ventilation during ECMO cannulation, the patient spent a total of 5 days on VV-ECMO and a total of 8 days in the intensive care unit. Six days after discharge, his pulmonary function test demonstrated no significant abnormalities. We present a rare case of early initiation of VV-ECMO in a patient with severe ARDS that served as a bridge to recovery.
