“…Recently, we have recognized a shift with the development of electrophysiologic, imaging, and serum biomarkers that can predict good outcomes, estimate brain injury severity, and track recovery. [17][18][19] Historically, neurological prognostication in comatose cardiac arrest survivors was dominated by an investigation published close to 4 decades ago. 20 In absence of any effective neuroprotective interventions available at that time, in a cohort of patients with overall 13% good or moderately disabled outcomes, the neuroprognostication scheme focused on identifying patients with poor outcomes and relied heavily on clinical neurologic findings at specific timeframes (ie, days 1, 3, and 7) after hypoxia or ischemia.…”
