ETYM See Bourn.
In medicine, destruction of body tissue by extremes of temperature, corrosive chemicals, electricity, or radiation. First-degree burns may cause reddening; second-degree burns cause blistering and irritation but usually heal spontaneously; third-degree burns are disfiguring and may be life-threatening.
Burns cause plasma, the fluid component of the blood, to leak from the blood vessels, and it is this loss of circulating fluid that engenders shock. Emergency treatment is needed for third-degree burns in order to replace the fluid volume, prevent infection (a dire threat to the severely burned), and reduce the pain. Plastic, or reconstructive, surgery, including skin grafting, may be required to compensate for damaged tissue and minimize disfigurement. If a skin graft is necessary, dead tissue must be removed from a burn (a process known as debridement) so that the patient's blood supply can nourish the graft.
