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 color.

• 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..
