Practice Patterns and Outcome of Extracorporeal Membrane Oxygenation Therapy for Severe Acute Respiratory Distress Syndrome in Indian ICUs.

Introduction: Extracorporeal membrane oxygenation (ECMO) is increasingly used in managing patients with severe acute respiratory distress syndrome (ARDS). The aim of the study is to describe the practice of ECMO and evaluate the outcomes in patients with severe ARDS in Indian intensive care units (ICUs).

Methods: Data of 39 patients with severe ARDS managed with ECMO in two tertiary centers between 2012 and 2018 were retrospectively studied.

Results: The mean age of the patient was 44.6 ± 13.5 years and 51% were female. Primary ARDS due to viral pneumonia was the common indication for ECMO. Mean APACHE II and Murray scores were 32.3 ± 7.8 and 3.64 ± 0.21, respectively. Prone ventilation and/or inhaled nitric oxide were used in 69.3% of the patients prior to ECMO therapy. Among 39 patients, 38 patients were managed with venovenous ECMO and 1 patient was managed with venoarterial ECMO. Average ECMO duration was 9.4 ± 6.9 days. Among the 17 (43.5%) patients successfully weaned off ECMO, 15 (38.5%) survived to discharge home. The average ICU and hospital length of stay were 18.9 ± 15.5 and 20.6 ± 16.6 days, respectively. While, sepsis was the common complication noted in 19 (49%) patients, bleeding and thrombotic complications were also noted in six and two patients, respectively.

Conclusion: In conclusion, ECMO support was used as rescue therapy in severe ARDS with a survival rate of 39%. Sepsis was the common complication of ECMO followed by bleeding and thrombosis.
