High altitude illnesses in Hawai'i

Area of Science:

• Altitude Medicine
• Traveler's Health
• Emergency Medicine

Background:

• High altitude illnesses, including High Altitude Headache (HAH), Acute Mountain Sickness (AMS), and High Altitude Cerebral Edema (HACE), range from mild to life-threatening.
• These conditions arise from rapid ascent without adequate acclimatization.
• High altitude illness is a prevalent concern in popular mountainous regions like Hawai'i.

Purpose of the Study:

• To emphasize the prevention and early diagnosis of Acute Mountain Sickness (AMS).
• To reduce the incidence and severity of high altitude illnesses.
• To prevent the progression of AMS to High Altitude Cerebral Edema (HACE).

Main Methods:

• Recommending slow, graded ascent to high altitudes.
• Advocating for the cessation of ascent upon the onset of AMS symptoms.
• Highlighting the use of acetazolamide for pharmacologic prophylaxis and treatment.

Main Results:

• Slow ascent and symptom monitoring are key preventive strategies.
• Early recognition and intervention of AMS can prevent progression to HACE.
• Acetazolamide is an effective prophylactic and therapeutic agent.

Conclusions:

• Effective prevention of high altitude illness relies on gradual acclimatization and prompt recognition of AMS symptoms.
• Early diagnosis and management of AMS are crucial to halt progression to HACE.
• Pharmacologic prophylaxis with acetazolamide is a vital tool in managing high altitude illnesses.
