Current prevention and management of acute mountain sickness

Acute mountain sickness was known to the Chinese in ancient times, as they traversed mountain passes between the Great Headache and Little Headache mountains into present-day Afghanistan. The Jesuit priest, Father Joseph Acosta, lived in Peru during the sixteenth century; he described both this syndrome and deaths which occurred in the high Andes. The incidence of high-altitude illness will rise as previously remote sites become more accessible to trekkers and skiers. Prevention and treatment are important concerns for those physicians who wish to advise their more adventuresome patients properly. This article incorporates a selected review of pertinent investigations, in the English-language literature over the past five years, into material previously presented at travel symposia for clinicians managing the prophylaxis and treatment of acute mountain sickness.
