However, with increasing altitude the body's defensesweakened and may not recover enough to supply tissue oxygen supply. There comes oxygen starvation of all organs and systems. In the cells of tissue begins to accumulate fluid. When fluid accumulates in the tissues of the brain, developing state, which was called the mountain of cerebral edema. This condition is life-threatening and, unfortunately, it is often observed in altitude sickness.
Depending on endurance and fitnessmountain sickness of the body may have different degrees of severity - from mild to severe. If you climb to altitude is very fast and without proper acclimatization, the first symptoms appear within a few hours. When patients complain of mild illness to:
- insomnia, bizarre dreams, frequent awakening during the night;
- shortness of breath or difficulty breathing;
- apathy, lethargy thinking, forgetfulness and light disturbance of consciousness;
- a state similar to the state of hangover: nausea, vomiting, headache, loss of appetite.
If measures are not taken, and rise to a heightcontinues, the patient's condition deteriorates. Comes muscle weakness, drowsiness, confusion, hallucinations occur, visual disturbances. Shortness of breath increases, there wheezing in the chest and coughing. Finally, the patient loses consciousness, there comes a coma, and death.
Alpine cerebral edema develops duringseveral hours, especially at the early symptoms of underestimation. The probability of brain edema development also depends on the rate of ascent and reached the height. With the rise in the height of 4000-5000 m over the frequency of this form of the disease is about 1%.
At the slightest sign of incipient cerebral edemahuman need to pull down the delay may lead to death of the patient, and, if possible, give oxygen (at a rate of 2-4 liters per minute). To reduce the symptoms and alleviate the condition affected, enter intramuscular dexamethasone (or give it to the inside, if the conditions allow the patient) at an initial dose of 8 mg (2 ampoules or 16 tab.), And then every 6 hours to give 4 mg (1 ampoule or 8 tablets )..
Currently, the most dexamethasonean effective drug for the treatment of high-altitude cerebral edema. I would like to warn against the use of furosemide (Lasix) in this situation. It does not reduce the swelling of the brain or in hypoxia or in traumatic brain injury, and therefore its use is not recommended in these situations.
And remember - the disappearance of symptoms does not occur immediately after the descent, so the patient should be placed under the supervision of medical staff.
A very important point yavlyaetsya addictiveheight. If you are going to climb to a higher altitude, it should be done gradually. At regular intervals, it is necessary to stop and rest, thus enabling the body to get used to the conditions of oxygen starvation. Rest should be long - 2-3 days, then the climbing or climbing to a height can be extended.
Another condition is to perform eachtraveler, rising high in the mountains. If you have spent some time at an altitude of 2000-3000 meters (skiing, walking), then at night have to go down to 500-600 meters below. Then the brain swelling does not threaten you.
Tip: each climber and traveler, while in the mountains, should monitor your health and at the first signs of altitude sickness immediately come down.
If you have more severe symptoms of altitude sickness (cerebral edema), you have to stop moving and stay warm. At the first opportunity you must go down below 400-500 meters.
If the patient is unconsciousstate and can not do, it is necessary to pull down on the stretcher. Do not leave the person alone if they have any symptoms of high-altitude cerebral edema. Moreover, it should not be allowed to go down on their own.
Patients are encouraged to sharply limitsalt intake (reduces swelling), and if the group is oxygen, then give the patient the opportunity from time to time to breathe pure oxygen. Doctors in these cases it is recommended to give the patient pain killers, sedatives and hormones.
From traditional medicine good effecthave such herbal preparations, such as ginger and cayenne pepper. They stimulate the processes of respiration and metabolism, so indispensable in hypothermia and altitude sickness.
Ginger is used for oral administration (20-25tincture drops per 100 ml water) and externally to the friction. You can brew tea from the dried ginger root powder (1/2 teaspoon of the root powder per 200 ml of boiling water. Infuse for 20 minutes).
Cayenne pepper is considered to be in the East"Crisis grass" and is used in cases when it is necessary to provide warming and stimulating effect. For immediate effect, 1/2 teaspoon cayenne pepper powder poured into 100 ml of water and drink in one gulp. It activates blood circulation, heart and lungs, thereby helping to overcome the effects of oxygen starvation and reduce swelling.
But remember: it is not recommended to use cayenne pepper if mountain sickness is accompanied by hypothermia (hypothermia).
