Double the Trouble: Successful Cannulation and Air Transportation of Two Obese Trauma Patients Requiring Extracorporeal Membrane Oxygenation

Acute Respiratory Distress Syndrome (ARDS) is a known and severe complication of thoracic trauma. Many patients, despite appropriate ventilator and medical support, continue to worsen requiring additional cardiopulmonary support with extracorporeal membrane oxygenation (ECMO). Additionally, obesity adds a layer of complexity in the management of trauma ARDS on ECMO. We describe the first U.S. Military air transportation mission via Critical Care Air Transport (CCAT) involving the cannulation and transportation of 2 obese trauma patients requiring ECMO support. We reviewed a cohort of 2 obese patients with ARDS secondary to trauma cannulated for venovenous ECMO and simultaneously transferred via Critical Care Air Transport to a DoD ECMO Center. We describe the logistics involved in the transport and management of obese trauma patients on ECMO. Both patients were safely cannulated and transported without complications, and survived their ECMO run and hospital stay. This is the first air transport of 2 obese ECMO patients simultaneously in U.S. Military history. This transport highlights the safety of cannulation and transportation of obese trauma patients, in addition to the flexibility and logistics needed to successfully complete an ECMO military transport.
