To analyze the association between hypothermia and neurologic complications among children who were treated with extracorporeal cardiopulmonary resuscitation (ECPR) using the Extracorporeal Life Support Organization (ELSO) international registry. ⋯ Of the 2,289 ECPR encounters, no difference in odds of neurologic complications were found between the hypothermia and non-hypothermia groups (AOR 1.10, 95% CI 0.80-1.51). However, hypothermia exposure was associated with decreased odds of mortality on ECMO (AOR 0.76, 95% CI 0.59-0.97), but no difference in mortality prior to hospital discharge (AOR 0.96, 95% CI 0.76-1.21) CONCLUSION: Analysis of a large, multicenter, international dataset demonstrates that hypothermia for greater than 24 hours among children who undergo ECPR is not associated with decreased neurologic complications or mortality benefit at time of hospital discharge.

To describe epinephrine dosing distribution using time-stamped data and assess the impact of dosing strategy on survival after ECPR in children. ⋯ Survivors received fewer doses than non-survivors after the first 10 minutes of CPR and although there was no statistical difference in survival based on dosing strategy, the findings of this study question the conventional approach to EPCR analysis that assumes dosing is evenly distributed.

Randomized Controlled Trial
Hypothermia versus Normothermia after Out-of-Hospital Cardiac Arrest; The effect on post-intervention serum concentrations of sedatives and analgesics and time to awakening.
This study investigated the association of two levels of targeted temperature management (TTM) after out-of-hospital cardiac arrest (OHCA) with administered doses of sedative and analgesic drugs, serum concentrations, and the effect on time to awakening. ⋯ This study of OHCA patients treated at normothermia versus hypothermia found no significant differences in dosing or concentration of sedatives or analgesic drugs in blood samples drawn at the end of the TTM intervention, or at end of protocolized fever prevention, nor the time to awakening.

Racial and ethnic disparities in the treatment and outcomes for witnessed out-of-hospital cardiac arrest (OHCA) in the United States have been previously described. We sought to characterize disparities in pre-hospital care, overall survival, and survival with favorable neurological outcomes following witnessed OHCA in the state of Connecticut. ⋯ Black and Hispanic Connecticut patients with witnessed OHCA have lower rates of bystander CPR, attempted AED defibrillation, overall survival, and survival with favorable neurological outcomes compared to White patients. Minorities were less likely to receive bystander CPR in affluent and integrated communities.

Extracorporeal membrane oxygenation (ECMO) provides temporary support in severe cardiac or respiratory failure and can be deployed in children who suffer cardiac arrest. However, it is unknown if a hospital's ECMO capability is associated with better outcomes in cardiac arrest. We evaluated the association between pediatric cardiac arrest survival and the availability of pediatric extracorporeal membrane oxygenation (ECMO) at the treating hospital. ⋯ A hospital's ECMO capability was associated with higher in-hospital survival among children suffering cardiac arrest in this analysis of a large United States administrative dataset. Future work to understand care delivery differences and other organizational factors in pediatric cardiac arrest is necessary to improve outcomes.
