Echocardiography In Venoarterial And Venovenous ECMO
Published 2014 · Medicine
After worldwide successes with ECMO for the 2009 pandemic influenza H1N1 [1, 2], and publication of the results of the Conventional Ventilatory Support Versus Extracorporeal Membrane Oxygenation for Severe Adult Respiratory Failure trial that showed a survival advantage for ECMO over conventional ventilator management for severe respiratory failure , there has been renewed enthusiasm for venovenous ECMO (VV ECMO) for pulmonary support. Similarly, venoarterial ECMO (VA ECMO) for acute cardiogenic shock is also becoming a more commonly used tool in the early management of critically ill patients as part of a treatment strategy to bridge to recovery, ventricular assist device implantation, or transplantation. Algorithms that incorporate early VA ECMO as part of the treatment for witnessed cardiopulmonary arrest (ECMO-assisted cardiopulmonary resuscitation) are also becoming more common and have resulted in a twofold increase in neurologically intact patients surviving to discharge  (Table 31.1).
