Mountain sickness

A syndrome to occur when I was put in the hypoxia state with the mountain sickness (こうざんびょう, altitude sickness). Often call it "a severe disability" recently (as the name of disease called heat stroke and the sunstroke was changed a name of to the heat stroke that expressed the condition of a patient more) [¹]; [²].

Summary

When I climb Takayama almost more than 2,400 meters and fall into a lack of oxygen state because air is thinner than ground in Takayama, various symptoms appear. The main symptom is a headache, nausea, vomiting, sleepiness (dizziness). Breaking wind to come from a sleep disorder, failure of muscular coordination, the low pressure such as swelling, sleepiness or the yawn of a face and hands and feet and the functional decline of the digestive organs elsewhere may appear. ^[3]It develops in a hypoxia state in several hours and disappears naturally generally several days after - one day later. However, in the case of a serious case, I cause highlands brain edema (High-Altitude Cerebral Edema; HACE) and highlands edema of the lungs (High-Altitude Pulmonary Edema; HAPE) and may result in death.

Preventive

But, as a risk factor, "the person who has given a symptom of the mountain sickness in the past" and "a person having the past of the migraine headache" have it pointed out not to mention a person with past illnesses of a respiratory system, the cardiovascular system elsewhere. In addition, it is easy to develop when I move to the highlands from altitude close to the sea surface to 2,500 meters on 1st. Even the altitude about 2,000 meters may develop depending on a person [⁴]. I can relatively easily measure the oxygen saturation in blood using a small pulse oximeter. I am expected if I use this when precaution is made before shifting to anoxia.

High place acclimation

It is paradoxical, but is known from experience without taking a break immediately on the day when I moved to the highlands more than 2,400 meters by walking around it for approximately from 30 minutes to one hour when it can promote high place acclimation of the human body.

In addition, the person that a symptom of mountain sickness such as a headache or nausea is easy to happen may take Brufen and diamox, decaDelon in a preventive purpose, but needs the prescription by the doctor (a trip medical society shows the medical institution which I can prescribe). ^[5]

Treatment

The correction of this knob is expected. (May, 2015)

Movement to the low land

If lack of oxygen is confirmed with a pulse oximeter, basic treatment is to move to the low land. In the case of a serious case, concentrated treatment is necessary promptly. As for the person and the person of the slight illness (I do not need a descent from a mountain) having a risk factor, coping to a person having the risk factor mentioned above includes evading it by the intense exercise in highlands 500 meters of [⁴] [⁴] to do below [⁶] by an ascent per day elsewhere elsewhere. There is the method to lower the altitude artificially by entering the pressurization capsule of 可搬式 called the Gamo bag when movement is difficult, and giving the atmospheric pressure in the capsule, but the use is not recommended by the progression of injury and symptom because altitude delays acclimatizing it in vain when a symptom is minimal [⁷].

Pharmaceutic treatment

If a symptom is slight, I take a diamox lock basically and drink medicine to other headaches and nausea and vomiting. ^[8] If a symptom is moderate, I take the medicine of a diamox lock and the decaDelon lock while giving oxygen and rest quietly in bed as much as possible. At this chance I descend a mountain as much as possible. I urgently request whether you descend a mountain immediately if a symptom becomes severe, and a sign of high place brain edema and the high place edema of the lungs appears. I inhale oxygen using a portable pressurization bag during an urgent request. ^[9] It is respiratory failure by the edema of the lungs to threaten a life most. It is thought that taking acetazolamide (diamox ®) [¹⁰] reduces edema of the lungs by a diuretic effect. In addition, (I apply treatment of the general edema of the lungs not highlands characteristics) the evidence does not have [⁴] to be possible as for the dosage of nifedipine and the prednisolone. [⁴] that a nonsteroidal antiinflammatory drug is effective requires the contraindicated (allergy, gastric ulcer, infants such as the asthma) attention of this drug for the headache due to the brain edema. In addition, it is not direct treatment, but may take low volume acetylsalicylic acid (aspirin ®) preventively to prevent a clot coming from the dehydration that is one of the symptoms of the mountain sickness [¹¹].
