burn (redirected from burned)

burn (burn) injury to tissues caused by the contact with heat, flame, chemicals, electricity, or radiation. First degree burns show redness; second degree burns show vesication; third degree burns show necrosis through the entire skin. Burns of the first and second degree are partial-thickness burns, those of the third degree are full-thickness burns.

first-degree burn  a burn that affects the epidermis only, causing erythema without blistering.

fourth-degree burn  a burn that extends deeply into the subcutaneous tissue; it may involve muscle, fascia, or bone.

full-thickness burn  third-degree b.

partial-thickness burn  second-degree b.

second-degree burn  a burn that affects the epidermis and the dermis, classified as superficial (involving the epidermis and the papillary dermis) or deep (extending into the reticular dermis). Called also partial thickness b.

third-degree burn  a burn that destroys both the epidermis and the dermis, often also involving the subcutaneous tissue. Called also full-thickness b.

burn

injury to tissues caused by contact with dry heat (fire), moist heat (steam or liquid), chemicals, electricity, lightning or radiation. The damage done by a burn includes shock due to the tissue damage, severe dehydration due to the loss of the protective effect of the skin, infection of the burn site, damage to lungs and eyes by exposure to high temperatures and smoke and debris, damage to external somatic addenda including vulva, teats, prepuce, scrotum. The critical decision in a burn case is whether to allow the animal a faint chance of recovery and therefore to continue with treatment. See also bushfire injury.

friction burn

the skin is damaged by the heat created by friction as by a rope burn, or when a dog is dragged by its lead behind a car.

full thickness burn

involves all of the epidermis and the dermis and may include underlying structures, as well. In alternative classification, it is equivalent to third- and fourth-degree burns.

partial thickness burn

involves part or all of the epidermis. Generally, equivalent to first- and second-degree burns.

solar burn

sunburn is noticeable mainly in white pigs, white cats and in dogs with little or no pigmentation on the nose (areas not protected by haircoat) or following close clipping. Of little importance in pigs, other than esthetic importance, but in dogs and cats causes actinic dermatitis, which occasionally precedes the development of squamous cell carcinoma. See also solar dermatitis, photosensitive dermatitis.

sole burn

damage caused to the sensitive laminae of the feet by the prolonged application of an overheated horseshoe during a shoeing session. The horse is very lame and part of the hoof may subsequently slough.
