abstractAcute mountain sickness
Altitude sickness usually occurs following a rapid ascent and can usually be prevented by ascending slowly. In most of these cases, the symptoms (that often manifest themselves 6-10 hours after ascent) are temporary and usually stop wth acclimatisation. Exertion aggravates the symptoms; they can include persistent rapid pulse, headache, sleep disturbance, fatigue and nausea. The rate of ascent, altitude attained, amount of physical activity, as well as individual susceptibility, are contributing factors to the onset and severity of high-altitude illness. Sometimes, altitude sickness become severe with pulmonary or cerebral edema. Altitude acclimatisation is the process to avoid altitude sickness; it is sintetized by the golden rul «climb high, sleep low». The most used drug to speed up the acclimatisation process before arriving at altitude and to treat mild cases of altitude sickness is acetazolamide, but other drugs are available. Key words: altitude sickness; hypoxia; headache; insomnia |
