Podcast 845: Hyperkalemic Cardiac Arrest

Contributor: Aaron Lessen, MD

Educational Pearls:

Hyperkalemia may cause cardiac arrest
Treatment of suspected hyperkalemic cardiac arrest begins with typical management of cardiac arrest including high-quality CPR, defibrillation if appropriate, and resuscitation medications

Administer calcium products to stabilize cardiac membrane and potassium shifting medications
If ROSC is achieved, initiate dialysis

There are several case reports of patients being dialyzed while CPR is ongoing, with some success

Dialysis during resuscitation may be an appropriate treatment for some patients
