A burn is a type of trauma to the skin and interior tissues of
the body due to heat, electricity, radiation, or certain
chemicals. Each year, approximately two million people in the
United States suffer burn injuries, resulting in some 300,000
serious injuries and 6,000 deaths.
The three main types of burns are: thermal, electrical, and
chemical.
Thermal burn injuries are the most common, occurring as a
result of residential fires, automobile accidents, matches,
gasoline, heaters or electrical devices. Some sources of thermal
burns include: open flames, hot liquids (such as coffee, grease,
or boiling water), and explosions.
Electrical burns occur when an electrical current runs through
the body at very high temperatures. An electrical current can
cause injury at its points of entry and exit, as well as the
muscles, tissues and organs through which it passes. Damage to
nerves, bones, and blood vessels can also occur. If an
electrical current passes through the center of the body, there
exists the potential for a fatal heart attack.
The conversion of chemical energy to thermal energy causes
chemical burns. Strong acids such as phosphorus or mustard gas
are examples of chemicals that cause burns. The severity of a
chemical burn depends upon the duration of the chemical's
contact with tissue; flushing the skin with water is essential
to preventing long-term tissue damage.
Each type of burn can further be described as a first-degree,
second-degree or third-degree burn. First-degree burns affect
only the epidermis, or outer layer of skin. Generally these are
superficial injuries that usually cause temporary redness,
swelling and pain.
Second-degree burns can cause damage to multiple layers of
skin, going beyond the epidermis to the dermis itself. These
burns are classified as either "superficial" or "deep."
Superficial burns only affect the outer portion of the dermis,
while deep burns extend to the deeper layers. Deep burns appear
as dry, white patches that are painful to the touch.
Second-degree burns don't usually require surgery, although
scarring is frequently a result.
The most serious of burn injuries is the third-degree burn.
Every layers of skin is affected, as well as underlying tissue
and/or organs, producing a black or brown leathery appearance.
Nerve endings are often destroyed, so third-degree burns usually
are not painful after the fact, but they can require surgical
skin grafting or transplants.
