Moonen C, et al. - This study aimed at assessing the link between global hemodynamics, blood gases, epileptiform EEG activity and survival after out-of-hospital CA (0HCA). In post-CA patients, epileptiform EEG activity was independently and inversely associated with survival and this effect was mainly driven by patients in whom this pattern is refractory over time despite treatment with anti-epileptic drugs. Findings revealed no association between hemodynamic factors, blood gas variables and epileptiform EEG activity after CA, although both hypotension, hypoxia and epileptic EEG activity were predictors of survival.
