What Researchers Did
This review examined methods for preventing and treating altitude sickness.
What They Found
Researchers found that slow ascent (300-600m per day) or spending at least nine nights above 2500m in the last 30 days can help prevent acute mountain sickness (AMS). For pharmacological prevention, acetazolamide (250-500mg, 12-24 hours before ascent) is recommended for AMS, while nifedipine (3 x 20mg daily, starting one day before) is suggested for individuals with a history of high-altitude pulmonary edema (HAPE).
What This Means for Canadian Patients
Canadian patients planning trips to high altitudes, such as the Rocky Mountains or international destinations, can use this information to prepare for and prevent altitude sickness. The findings offer practical advice on gradual ascent and specific medications like acetazolamide or nifedipine to reduce the risk of acute mountain sickness or high-altitude pulmonary edema.
