Classification and symptoms of the burn

Burns are divided into 3-4 degrees of severity, which depend on the depth of the destroyed skin layers and allow an initial prognosis of the healing prospects. The higher the temperature and the longer the exposure time to the body, the more severe the burn.

Burn I °: It only affects the epidermis, is noticeable by redness, swelling and pain and usually heals completely. A more common 1st degree burn is sunburn.
Burn II °: It reaches into the dermis, which contains small vessels for skin supply, as well as sebum and sweat glands, as well as the hair roots. The symptoms are severe pain, redness, swelling and blistering. Depending on the depth of the affected dermis, the 2nd degree burn is subdivided into type 2a, which usually heals completely like the 1st degree burn, as well as type 2b, which results in scarring.

Burn III °: Here the subcutaneous tissue is also affected, whereby the intensity of the heat exposure often overcooked (white) and charred (black) Has left tissue. Since the cutaneous nerves are destroyed at this level, the patients usually no longer experience pain. Affected skin is irretrievably lost and has to be replaced with a transplant.
Burn IV °: This is the most severe charring that has already reached not only the skin, but also any underlying tissue (muscles, bones).
