Podcast #276: Angioedema

Author: John Winkler, M.D.

Educational Pearls

  • Angioedema is immediately life-threatening due to airway obstruction.
  • Mechanisms include allergic reaction (histamine-related) or bradykinin-related (ACE-inhibitor, C1 esterase inhibitor deficiency).
  • The bradykinin-related mechanism will not respond to the traditional meds used for anaphylaxis. Instead, use FFP to replace depleted factors.
  • If a patient displays signs of respiratory compromise, intubation is indicated. Anesthesia should be consulted as this will be a very difficult airway.
