Loss of temperature and frostbite how to do? How to treat?

The most important first-aid principle for the loss of temperature is to prevent patients from continuing to lose body temperature, and to gradually assist the patient in obtaining normal body temperature, taking the patient away from the harsh low-temperature environment and moving it into a warm tent or mountain house. Remove wet and cold clothing and wrap the patient in warm clothing, sleeping bags, etc. If the patient is conscious, he may be allowed to drink some hot and sweet drinks, and if he is unconscious, he is allowed to lie down in a restored position. The patient may be given respiratory and cardiac arrest. The cardiopulmonary bypass should be performed and the doctor should be sent to the doctor as soon as possible. Remember not to drink to the patient, nor to wipe or massage the limbs of the patient, nor to encourage the patient to exercise.

The reason for frostbite is that the ends of the body's circulatory system, such as fingers, toes, ears, nose, etc., are exposed to ice or cold weather for a long time, or they are exposed to ice and snow, resulting in freezing damage to the skin or subcutaneous tissues. Symptoms of frostbite include: tingling in the affected area and gradual or numbness, skin stiffness, pale or blue spots, difficulty or dullness of the affected area. At the beginning, it was frostbite in the skin or deep, and it was difficult to tell. The symptoms were similar. In addition, frostbite may be accompanied by a loss of temperature, and the latter should be dealt with first aid. If there is only frostbite, you should slowly warm the affected area to prevent deep tissue from being damaged. Move the patient to a warm tent or mountain hut as soon as possible, and gently remove the clothing and any restraints such as rings, watches, etc. from the wounded area. Use skin heat transfer to the skin, warm the affected area, or immerse the affected area with warm water. Frostbite ear, nose or face can be covered with warm towels. The temperature of the water should be acceptable to the wounded and slowly increase. If the affected area has recovered blood color and feel within 1 hour, you can stop the [warm] emergency operation. Second, raise the affected area to reduce swelling. Wrap or lightly cover affected areas with gauze bandages or soft clothing. Unless necessary, pay attention to non-abrasive or massage the affected area, and do not radiate heat to warm the affected area.

The affected area after warming should not be exposed to the cold again, and do not walk on the feet of [thawing].
