FOAMcast - An Emergency Medicine Podcast

In this episode we briefly review hyperkalemia and the principles of emergent treatment. Then we explore, in-depth, the role of insulin and dextrose including the incidence of hypoglycemia and pearls to reduce this side effect.


  • 10-20% of patients treated with insulin/dextrose for hyperkalemia get hypoglycemic
  • Consider giving 5 units insulin instead of 10 units
  • Check the glucose for hours (dextrose lasts <1 hr, insulin lasts ≥2 hours)
  • Beware of insulin in patients with renal insufficiency or with near normal starting glucose.

Thanks for listening!
