ASAIO J 2022 May 7. Epub 2022 May 7.

From the Department of Allergy, Pulmonary, and Critical Care Medicine, Vanderbilt University Medical Center, Nashville, Tennessee.

Coronavirus disease 2019 (COVID-19) has increased the demand for extracorporeal membrane oxygenation (ECMO) and introduced distinct challenges to patient selection for ECMO. Standardized processes for patient selection amidst resource limitations are lacking, and data on ECMO consults are underreported. We retrospectively reviewed consecutive adult ECMO consults for acute respiratory failure received at a single academic medical center from April 1, 2020, to February 28, 2021, and evaluated the implementation of a multidisciplinary selection committee (ECMO Council) and standardized framework for patient selection for ECMO.

Extracorporeal Membrane Oxygenation Circuits in Parallel for Refractory Hypoxemia in COVID-19: A Case Series.

ASAIO J 2022 May 5. Epub 2022 May 5.

From the Department of Thoracic Surgery, Vanderbilt University Medical Center, Nashville, Tennessee.

Refractory hypoxemia despite the use of extracorporeal membrane oxygenation (ECMO) for coronavirus disease 2019 (COVID-19)-related acute respiratory distress syndrome remains a challenging problem. A single ECMO circuit may not provide adequate physiologic support in the setting of an elevated cardiac output, physiologic demand, and impaired gas exchange. In select patients with refractory hypoxemia, addition of a second ECMO circuit in parallel can improve oxygenation, facilitate lung protective ventilation, awakening, and physical rehabilitation.
