Awake Venovenous Extracorporeal Membrane Oxygenation for Coronavirus Disease 2019 Acute Respiratory Failure.

UNLABELLED

Implantation of venovenous extracorporeal membrane oxygenation as an alternative to invasive mechanical ventilation, an "awake approach," may facilitate a lung- and diaphragm-protective ventilatory strategies without the associated harms of endotracheal intubation, positive pressure ventilation, and continuous sedation. This report presents the characteristics and outcomes of the patients treated with the awake venovenous extracorporeal membrane oxygenation approach.

DESIGN

Retrospective case series.

SETTING

Monocenter study.

PATIENTS

Severe acute respiratory syndrome coronavirus 2 patients with acute respiratory failure treated with venovenous extracorporeal membrane oxygenation instead of invasive mechanical ventilation from March 2020 to March 2021.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Physiologic and laboratory data were collected at admission to the ICU, prior to and after venovenous extracorporeal membrane oxygenation implantation, and at decannulation. Seven patients were treated with venovenous extracorporeal membrane oxygenation instead of invasive mechanical ventilation due to hypoxemia with a median Pao/Fio ratio at implantation of 76 (interquartile range, 59-92). Four patients in the awake group subsequently required invasive mechanical ventilation, and only one patient (14.3%) died. There were no significant complications attributed venovenous extracorporeal membrane oxygenation.

CONCLUSIONS

This report demonstrates that in a selected group of patients, an "awake" venovenous extracorporeal membrane oxygenation approach is feasible and may result in favorable outcomes.
