Abstract 375: Utility of Routine Early Head Computed Tomography Following Non-Traumatic Out-Of Hospital Cardiac Arrest

Introduction: Head computed tomography (CT) is frequently performed in survivors of out-of-hospital cardiac arrest (OHCA). However, the clinical utility of routine, early head CT in these patients is not well understood. We sought to characterize the associations between findings on early head CT with presenting characteristics and outcomes in survivors of OHCA. Hypothesis: Presence of early intracranial swelling is associated with poor outcomes. Methods: This is a retrospective analysis from a multicenter cohort of 432 patients with non-traumatic OHCA between 2/1/17 through 4/1/19. Patients were included if they underwent head CT Result: Early head CT ( Conclusions: In survivors of non-traumatic OHCA, routine, early (
