The loss or damage of the superficial layer of skin as a result of a body part rubbing or scraping across a rough or hard surface.
A condition resulting when veins of the neck are open to the environment and suck in air.
The removal of a body part (complete avulsion).
An injury in which soft tissue is torn completely loose or is hanging as a flap.
An injury in which the soft tissue receives more energy than it can absorb without injury, from thermal heat, frictional heat, toxic chemicals, electricity, or nuclear radiation.
An injury in which damage occurs beneath the skin or mucous membrane but the surface remains intact.
Swelling in a confined space that produces dangerous pressure; may cut off blood flow or damage sensitive tissue.
A burn produced by touching a hot object.
The presence of infective organisms or foreign bodies such as dirt, gravel, or metal in a wound.
A bruise without a break in the skin.
A significant metabolic derangement that can lead to renal failure and death. It develops when crushed extremities or other body parts remain trapped for prolonged periods.
The inner layer of the skin, containing hair follicles, sweat glands, nerve endings, and blood vessels.
The discoloration associated with a closed wound; signifies bleeding.
The outer layer of skin that acts as a watertight protective covering.
The thick, coagulated crust or slough of leathery skin that develops following a burn.
The displacement of organs outside the body.
A thermal burn caused by flames touching the skin.
An electrothermal injury caused by arcing of electric current.
full-thickness (third-degree) burns
The burns that affect all skin layers and may affect the subcutaneous layers, muscle, bone, and internal organs, leaving the area dry, leathery, and white, dark brown, or charred.
Blood collected within the body's tissues or in a body cavity.
An injury to the airway as a result of breathing smoke and toxic chemicals into the lungs and airway.
A smooth or jagged open wound.
The linings of body cavities and passages that are in direct contact with the outside environment.
The dressings made of Vaseline gauze, aluminum foil, or plastic that prevent air and liquids from entering or exiting a wound.
An injury in which there is a break in the surface of the skin or the mucous membrane, exposing deeper tissue to potential contamination.
A formula that recommends giving 4 mL of normal saline for each kilogram of body weight, multiplied by the percentage of body surface area burned during the first 24 hours following the burn; one half of the volume is given in the first 8 hours and the other half in the next 16 hours; sometimes used during lengthy transport times.
partial-thickness (second-degree) burns
The burns affecting the epidermis and some portion of the dermis but not the subcutaneous tissue, characterized by blisters and skin that is white to red, moist, and mottled.
An injury that penetrates the skin, resulting from a sharp, pointed object or a blunt object traveling at sufficient speed, such as a bullet.
Describes an animal that is infected with rabies.
rule of nines
A system that assigns percentages to sections of the body, allowing calculation of the amount of skin surface involved in the burn area.
rule of palms
A system that estimates total body surface area burned by comparing the affected area with the size of the patient's palm, which is roughly equal to 1% of the patient's total body surface area.
A burn produced by hot liquids.
A burn that has been caused by direct exposure to hot steam exhaust, as from a broken pipe.
superficial (first-degree) burns
The burns affecting only the epidermis, characterized by skin that is red but not blistered or actually burned through.
