Severe burns are life-threatening severe burns, carbonization of tissues. The severity of burns depends on the extent and depth of the injured tissue. The depth of burn can be divided into I, II and III degrees. Severe burns require immediate treatment, preferably in a hospital with a burn specialist. First-aid personnel apply masks to oxygen in the wounded to reduce the impact of carbon monoxide and toxic gases on the wounded in the fire.

Burns of three or more degrees account for more than 10% of the total surface area.

The burn surface can be white, soft or black, charred leather. Since the burnt skin becomes pale, it is often mistaken for normal skin in white-skinned people, but it does not change color when pressed. Destroyed red blood cells can make the skin of the burn appear bright red, occasionally blisters, and the hair in the burned area is easily pulled out and the feeling is reduced. The third degree burn area generally has no pain. Because the nerve endings of the skin are destroyed.
Differential diagnosis of severe burns:
1. Mild burn injury is the lightest. Burn skin redness, pain, obvious tenderness, exudation or edema. Partially whitened when the injured area was lightly pressed, but no blisters.
2, moderate burn: moderate burn refers to deep burn injury, the formation of serum-filled burn blister, tissue necrosis.
