[Acute mountain sickness and high altitude cerebral and pulmonary edema].

Altitude hypoxia is responsible for acute mountain sickness. It can worsen and generate a high altitude cerebral edema, which can be fatal. After reminding the reader clinical and epidemiological facts, this review aims to present new insights of the physiopathological continuity between these two illnesses and the current preventive and treatment tools. Have new medications, as sumatriptans, kept their promises? Have recent studies provide evidence of empirical use of old drugs as aspirin or ibuprofen? What are acetazolamide and dexamethasone places? This wide range of medication doesn't replace non-pharmacological tools.
