Podcast #264: Witnessed Cardiac Arrest

Author: Aaron Lessen, M.D.

Educational Pearls

• For patients with in-hospital cardiac arrest, intubation in the 1st 15 minutes of resuscitation was associated with worse outcomes (mortality, neurologic outcome). This is likely due to cessation of high-quality CPR and defibrillation during the intubation sequence.
• In those with an in-hospital, shockable, cardiac arrest, administration of epinephrine before the 2nd defibrillatory shock was associated with worse outcome. This was likely due to the cessation of high-quality CPR.
• For in-hospital cardiac arrest, resuscitation should focus on high-quality CPR.
