ACUTE MOUNTAIN SICKNESS: AN HISTORICAL REVIEW, WITH SOME EXPERIENCES FROM THE PERUVIAN ANDES

A study of the prevention of acute mountain sickness was performed on a group of Australian mountaineers. Frusemide in a dosage of 40 mg per day was given orally for three days to the mountaineers as they travelled from Lima at sea‐level to Cuzco, at an altitude of 3,500 metres, in the Peruvian Andes. This régime proved effective in lessening both the incidence and severity of the symptoms, namely headaches, insomnia and gastrointestinal symptoms.
