A height of cerebral edema (HACE abbreviated from English. High-altitude cerebral edema ) is a dangerous serous fluid retention or collection in the brain that may be affected by the climbers. The skull cannot expand due to its bony structure and a dangerous increase in pressure in the brain occurs. It comes to the height rush and the height fever . If immediate therapeutic measures are not taken, high altitude cerebral edema is usually fatal. In combination with high altitude pulmonary edema (HAPE), the mortality rate is particularly high.
Occurrence
Altitude cerebral edema occurs in only about 0.3% of mountaineers who are at an altitude of 3,000 meters or higher, but the mortality rate is about 40%.
Symptoms
The main symptom of high altitude brain edema are ataxias . This occurrence of movement disorders is an important sign of the transition from acute altitude sickness to altitude cerebral edema, which can develop from severe acute altitude sickness within a short period of time. Further symptoms are severe headaches, nausea and vomiting, dizziness, hallucinations, photophobia, irrational behavior, neurological changes, fever, inresponsibility, impaired consciousness, coma and a 24-hour urine volume of less than 500 ml.
