Outcome of Patients on Prolonged V-V ECMO at a Tertiary Care Center in India.

Abstract

Extracorporeal membrane oxygenation (ECMO) is a life-support system that provides cardiopulmonary support. With recent advances, the duration of ECMO has increased but data on the outcomes of prolonged V-V ECMO are limited and inconsistent. It is a retrospective observational study done at a tertiary care center in Kolkata to study the outcome of patients receiving prolonged V-V ECMO defined as >14 days. A total of 22 patients received prolonged ECMO support. Fifteen patients (68.2%) had severe coronavirus disease-2019 (COVID-19). The mean duration of invasive mechanical ventilation (IMV) before ECMO was 5 days. Baseline PaO2/FiO2 (p/f) ratio was 82 and Murray score was 3.5. The mean duration of ECMO support was 27.18 days (SD: 11.59). Five patients (22.7%) had minor bleeding and one patient had oxygenator failure. Survival at hospital discharge was seven patients (31.8%). Duration of ECMO support alone should not represent a basis for decision making to decide futility or continuation of ECMO support. Prolonged ECMO in acute respiratory distress syndrome (ARDS) has minor complications and can lead to recovery in almost one-third of the patients. Goel K, Chakraborty A, Goel A.
