Frostbite Symptoms and Measures:
Frostbite Definition
Frostbite refers to the prolonged exposure of a part of the body to the cold environment, the skin and tissues of the body and the tissues are therefore injured.
Symptoms:
The skin feels very cold and is a little red before frostbite.
The skin loses its color at first, but as frostbite develops, it turns white or yellow with a grayish tinge, or white with blotches.
Blisters may form. It may hurt a little, or you may not even know you have frostbite
The initial symptom of frostbite (frostnip) is tingling, followed by numbness and stiffness, with the affected area appearing pale in color; it can be fully recovered if it is warmed up. If the initial frostnip is not dealt with, it will progress to superficial frostnip, at this time the skin and subcutaneous tissue has been necrotic, the skin is still pale or slightly gray, touch cold but soft; thawing will be red, pain, one to a few days after the formation of large blisters as second-degree burns; and then a few days after the blisters dry to form a black scorched scab (eschar), such as the absence of concurrent infections, and finally will be replaced by the newborn skin.
Frostbite is the most common form of skin infection in the world.
Frostbite treatment measures:
Move to a warm place and keep the affected area in warm, dry air. Remove restraints to avoid swelling that would prevent removal. Keep the affected part warm in gradually adjusted warm water (38.8~40.5 degrees Celsius)
Do not re-expose to cold, elevate the affected part to reduce pain and swelling, then wrap the affected part with clean gauze and send it to the hospital; the purpose of first aid is to normalize the body fluids of the cold knots. Therefore, if the area around the affected part can be warmed, it can be cured quickly. It is forbidden to soak the affected part directly into hot water or to roast the affected part with fire, as this will aggravate the frostbite. As massage can cause, remember not to do massage on the affected area.
Note---Do not massage, bake, and puncture the blisters to prevent infection.
