Extracorporeal cardiopulmonary resuscitation (ECPR) has been shown to improve neurologically favorable survival for patients with refractory ventricular tachycardia (VT)/ventricular fibrillation (VF) out-of-hospital cardiac arrest. Prior studies of the impact of age on outcomes in ECPR have demonstrated mixed results and we aim to investigate this relationship. ⋯ Age is associated with neurologically favorable survival to discharge for patients receiving ECPR for refractory out-of-the-hospital VT/VF cardiac arrest. However, with a survival rate of 23% in the oldest age group, caution should be used when choosing age criteria for patient selection.

Outcomes of conventional cardiopulmonary resuscitation are improved when the initial rhythm is shockable (ventricular fibrillation or pulseless ventricular tachycardia). In children, the first documented rhythm is typically asystole or pulseless electrical activity. We evaluate the role the initial rhythm plays in outcomes for children undergoing extracorporeal cardiopulmonary resuscitation (ECPR) for in-hospital cardiac arrest. ⋯ In children with in-hospital cardiac arrest undergoing ECPR, there was no significant difference in survival or favorable neurologic outcome between those with initial shockable rhythm compared to non-shockable rhythm. Further investigation to evaluate ECPR patient characteristics and outcomes is warranted to help guide eligibility and ECMO deployment practices.

To assess the hemodynamic effects of head elevation on cerebral perfusion during cardiopulmonary resuscitation (CPR) in a porcine model of cardiac arrest. ⋯ HUP did not affect cerebral perfusion pressure and it significantly decreased internal carotid blood flow.
