Gradual ascent is impractical for personnel deploying to the South Pole due to logistical challenges. Prevention of altitude illness relies on prophylactic medications such as acetazolamide and behavioral modifications including hydration and avoidance of overexertion. We present three recent cases of altitude illness that occurred in previously healthy individuals at the South Pole.

Objectives: The unique challenges posed by the Antarctic environment include both physiological and psychological stressors to the individual as well as the limited onsite medical capabilities available to address them. This report compares medical clinic utilization among 3 US Antarctic stations to identify differences in diagnostic frequency and utilization of clinic resources under current medical prescreening regimes for summer and winter seasons.
Methods: Clinic data from 3 Antarctic locations (McMurdo Station, Amundsen-Scott South Pole Station, and Palmer Station) for the 2013-2014 Antarctic year were reviewed for patient encounter frequency by season, and provider-assigned visit diagnostic category.

Introduction: Each year, the US Antarctic Program rapidly transports scientists and support personnel from sea level (SL) to the South Pole (SP, 2835 m) providing a unique natural laboratory to quantify the incidence of acute mountain sickness (AMS), patterns of altitude related symptoms and the field effectiveness of acetazolamide in a highly controlled setting. We hypothesized that the combination of rapid ascent (3 hr), accentuated hypobarism (relative to altitude), cold, and immediate exertion would increase altitude illness risk.
Methods: Medically screened adults (N = 246, age = 37 ± 11 yr, 30% female, BMI = 26 ± 4 kg/m(2)) were recruited.
