EPISODE 31: The Beef with Bicarb! The Use of Sodium Bicarbonate in Hyperkalemia with Jimmy Pruitt

Introduction

  1. Sodium bicarbonate was previously recommended for hyperkalemia treatment and was once considered a first-line agent for the transcellular shift.
  2. Studies evaluating the beneficial effects of sodium bicarbonate used an isotonic infusion commonly  ~ 150 mEq/ 1000ml
  3. Hypertonic sodium bicarbonate or “amp of bicarb” has an osmolality of 2000 mOsm, about 7x higher than plasma.
  4. There’s controversy as to whether hypertonic sodium bicarbonate is beneficial for the acute treatment of hyperkalemia due to modifications in the mechanism of action.
