Extracorporeal Membrane Oxygenation: Set-up, Indications, and Complications

Extracorporeal membrane oxygenation (ECMO) occupies an increasingly important position in the clinic for the management of cardiac and/or pulmonary failure. As a rescue therapy, ECMO can support patients following respiratory or cardiac compromise to act as a bridge to recovery, to decision, or to transplant. This chapter reviews briefly the history of ECMO implementation as well as device modes, from veno-arterial, veno-venous, veno-arterial-venous, and veno-venous-arterial set-ups. The importance of acknowledging complications that can arise in each of these modes cannot be overlooked. Both bleeding and thrombosis are inherent risks to the use of ECMO and the existing strategies for management are reviewed. The device also elicits an inflammatory response, and the use of extracorporeal approaches can lead to infection, both of which are important to examine when reflecting how ECMO can be successfully implemented in patients. This chapter both discusses the understanding of these various complications and highlights the need for future research.
