BuRN

A burn is a type of injury to the skin caused by heat, electricity, chemicals, light, radiation or friction. Most burns only affect the skin. Rarely deeper tissues, such as muscle, bone, and blood vessel can also be injured.


Classification of Burn:

1. First degree burn: limited to redness, a white plaque and minor pain at the side of injury. Involve only the epidermis. Most sunburns can be included as first degree burn.



2. Second degree burn: manifest as erythema(redness) with superficial blistering of the skin, and can involve more or less pain depending on the level of nerve involvement. Involve the superficial dermis and may also involve the deep dermis layer.



3. Third degree burn: occur when the epidermis is lost with damage to the subcutaneous tissue. Result in scarring and exhibit loss of hair shaft and keratin. May require grafting. These burn are not painful, as all the nerves have been damaged by the burn and are not sending pain signals.



4. Fourth degree burn: occur when heat damage destroys the dermis and muscle is affected. result in scarring and the loss of hair shafts, skin grafting will be needed and permanent motor damage may occur.
