The Use of Extracorporeal Membrane Oxygenation in Severely Burned Patients: A Survey of North American Burn Centers.

Abstract

Respiratory failure and acute respiratory distress syndrome can occur in burn patients with or without inhalational injury and can significantly increase mortality. For patients with severe respiratory failure who fail conventional therapy with mechanical ventilation, the use of venovenous extracorporeal membrane oxygenation (ECMO) may be a life-saving salvage therapy. There have been a series of case reports detailing the use of ECMO in burn patients over the last 20 years, but very little is currently known about the status of ECMO use at burn centers in North America. Using a web-based survey of burn center directors in Canada and the United States, we examined the rate of usage of ECMO in burn care, barriers to its use, and the perioperative management of burn patients receiving ECMO therapy. Our findings indicate that approximately half of the burn centers have used ECMO in the care of burn patients, but patient volume is very low on average (less than 1 per year). Of centers that do use ECMO in burn care, only 40% have a specified protocol for doing so. Approximately half have operated on patients being actively treated with ECMO therapy, but perioperative management of anticoagulation varies widely. A lack of experience and institutional support and a perceived lack of evidence to support ECMO use in burn patients were the most commonly identified barriers to more widespread uptake. Better collaboration between burn centers will allow for the creation of consensus statements and protocols to improve outcomes for burn patients who require ECMO.
