Extracorporeal membrane oxygenation has emerged as a treatment of choice for refractory hypoxemia in the intensive care unit. Severe hypoxemia unresponsive to conventional lung-protective mechanical ventilation could also occur in the operating room from severe bronchospasm, pulmonary contusions, or acute respiratory distress syndrome. We report a case of acute hypoxic respiratory failure in an adolescent with blunt chest trauma that was successfully managed with the intraoperative initiation of venovenous extracorporeal membrane oxygenation during the initial damage control surgery.
