Abstract:
We describe our novel technique of Pump Controlled Retrograde Trial Off that relies on the retrograde flow to maintain circuit integrity and allow a longer trial off from venoarterial extracorporeal membrane oxygenation support without circuit clot formation or significant patient hemodynamic compromise. This technique avoids the insertion of an arteriovenous bridge and the need to clamp the circuit. We present data on five neonatal patients who were trialled off using this method.

The latent period of contraction marks the onset of excitation-contraction coupling, when the action potential propagates across the sarcolemma, preparing the muscle fibers for contraction. As the fibers enter the contraction phase, the...
