Podcast 625: High Altitude Cerebral Edema (HACE)

Podcast 625: High Altitude Cerebral Edema (HACE)

Contributor: Tom Seibert, MD

Educational Pearls:

  • High altitude cerebral edema (HACE) is the end stage of acute mountain sickness and is diagnosed when patients develop neurologic dysfunction, ataxia, and altered mental status.
  • The pathophysiology of HACE is thought to be due to increased cerebral blood flow and increased capillary permeability causing vasogenic edema and brain swelling
  • HACE is linked to extreme altitude
  • Rapid descent should be done as soon as possible for this potentially fatal condition
  • Oxygen can be supportive
  • Dexamethasone is also typically indicated (8mg initially followed by 4 mg every 6 hours)

Editor's note: HACE can occur at altitudes as low as 8000 feet so don't automatically assume it can't/doesn't happen in the US
