Corticosteroids Adverse Reaction

We aim to investigate the effects of pre-arrest corticosteroid use for any reason on the time of return of spontaneous circulation in patients experiencing witnessed cardiac arrest, either in-hospital or out-of-hospital. Additionally, we plan to study the effects of corticosteroid use on post-ROSC administration of vasoactive agents, required dosage of vasoactive agents and number of vasoactive agents needed in order to reach targeted blood pressure levels.
