Circulatory support & extracorporeal membrane oxygenation (ECMO) using centrifugal pump and percutaneous cannula

Abstract

During the last year, we performed circulatory and respirarory assist using centrifugal pump (Biopump) and membrane oxygenator. 2 patients with adult respiratory distress syndrome were treated with venovenous bypass utilizing percutaneous catheters. We achieved 3.0 liters in these patients. The other 2 patients developing circulatory failure following open heart surgery were treated with left heart bypass and/or venoarterial bypass. One of them were able to wean from circulatory assist and survived. Biopump and percutaneous cannula appear to be effective mechanical support devices.
