Clinical Characteristics and Outcomes of Adults with Peripheral Extracorporeal Membrane Oxygenation in A Developing Country: A Single Center 8-Year Retrospective Study

Introduction

In our institute, we began using peripheral veno-arterial (VA) extracorporeal membrane oxygenation (ECMO) in 2010, and peripheral veno-venous (VV) ECMO in 2015. This study aimed to describe clinical characteristics and outcomes in those patients.

Methods

We reviewed retrospective data of adults receiving peripheral ECMO from January 2010 to December 2017 and divided it into two groups for analysis: VA- and VV-ECMO.

Results

There were 28 patients in the VA group and 12 in VV. For VA, the mean (SD) age was 58.5 (17.2) years. The most common indication was cardiac arrest (12 patients, 42.9%); 15 patients (53.6%) were on intra-aortic balloon pump concomitantly. In the VV cohort, the mean age was 53.3 (16.2) years. Eleven (91.7%) patients had acute respiratory distress syndrome as an indication. The mortality rate of VA-ECMO was 85.7%, and VV was 58.3%.

Conclusion

The mortality rate in our ECMO center was considerably higher than that in the international registry report. Improved team education, rigid patient selection criteria, and a reimbursement protocol should lead to ameliorated outcomes.
