Classification of Burns
What are the classifications of burns?
Burns are classified as first-, second-, or third-degree, depending on how deep and
severe they penetrate the skin's surface.
First-degree (superficial) burns. First-degree burns affect only the epidermis, or outer layer of skin. The burn site
is red, painful, dry, and with no blisters. Mild sunburn is an example. Long-term
tissue damage is rare and usually consists of an increase or decrease in the skin
Second-degree (partial thickness) burns. Second-degree burns involve the epidermis and part of the dermis layer of skin.
The burn site appears red, blistered, and may be swollen and painful.
Third-degree (full thickness) burns. Third-degree burns destroy the epidermis and dermis and may go into the subcutaneous
tissue. The burn site may appear white or charred
Fourth degree burns. Fourth degree burns also damage the underlying bones, muscles, and tendons. There
is no sensation in the area since the nerve endings are destroyed.
