Steroid, Thiamine and Ascorbic Acid for Comatose Out-of-hospital Cardiac Arrest Survivors

The mortality and neurological outcomes among out-of-hospital cardiac arrest survivors have not improved despite the medical advances. The whole body ischemia/reperfusion injuries after cardiac arrest mainly damaged the brain. To improve the neurologic outcome among those patients, additional interventions would be warranted. The investigators hypothesize that the combined use of cortisol, ascorbic acid (vitamin C), and thiamine during the early post-resuscitation period would attenuate the whole-body ischemia/reperfusion injuries among the out-of-hospital cardiac arrest survivors treated with targeted temperature management.
