Patients resuscitated from cardiac arrest have variable severity of primary hypoxic ischemic brain injury (HIBI). Signatures of primary HIBI on brain imaging and electroencephalography (EEG) include diffuse cerebral edema and burst suppression with identical bursts (BSIB). We hypothesize distinct phenotypes of primary HIBI are associated with increasing cardiopulmonary resuscitation (CPR) duration. ⋯ Brain injury phenotype is related to CPR duration, which is a surrogate for severity of HIBI. The sequence of most likely primary HIBI phenotype with progressively longer CPR duration is awake, coma without BSIB or edema, BSIB, and finally cerebral edema.

There is a critical need to identify factors that can prevent emotional distress post-cardiac arrest (CA). CA survivors have previously described benefitting from utilizing positive psychology constructs (mindfulness, existential well-being, resilient coping, social support) to cope with distress. Here, we explored associations between positive psychology factors and emotional distress post-CA. ⋯ Higher levels of mindfulness, existential well-being, resilient coping, and perceived social support were each associated with less emotional distress. Future intervention development studies should consider these factors as potential treatment targets.

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.
