Description:

Author: Nick Hatch, MD.

Educational Pearls:

 

  • A common concern using vasopressors is the risk of digital and mesenteric ischemia.
  • The absolute risk of digital ischemia and/or mesenteric ischemia is pretty low. Norepinephrine at its highest doses carries a 5% digital ischemia rate and a 2% mesenteric ischemia rate.
  • The studies demonstrating this complication were predominately patients with pre-existing liver disease.
  • Providers commonly mistake purpura fulminans, a common complication of sepsis, for digital ischemia.
