One
of the most painful injuries that one can ever experience is a burn injury. When
a burn occurs to the skin, nerve endings are damaged causing intense feelings of
pain. Every year, millions of people in the United States are burned in one way
or another. Of those, thousands die as a result of their burns. Many require
long-term hospitalization. Burns are a leading cause of unintentional death in
the United States, exceeded in numbers only by automobile crashes and falls.
Serious burns are
complex injuries. In addition to the burn injury itself, a number of other
functions may be affected. Burn injuries can affect muscles, bones, nerves, and
blood vessels. The respiratory system can be damaged, with possible airway
obstruction, respiratory failure and respiratory arrest. Since burns injure the
skin, they impair the body's normal fluid/electrolyte balance, body temperature,
body thermal regulation, joint function, manual dexterity, and physical
appearance. In addition to the physical damage caused by burns, patients also
may suffer emotional and psychological problems that begin at the emergency
scene and could last a long time.
Classifying
burns
Burns are classified
in two ways: Method and degree of burn.
Methods
are:
- Thermal
- including flame, radiation, or excessive heat from fire, steam, and hot
liquids and hot objects.
- Chemical
- including various acids, bases, and caustics.
- Electrical
- including electrical current and lightning.
- Light
- burns caused by intense light sources or ultraviolet light, which includes
sunlight.
Radiation - such as from nuclear sources. Ultraviolet light is also a source
of radiation burns.
Never assume the
source of a burn. Gather information and be sure.
Degrees
are:
- First
degree burns
are superficial injuries that involve only the epidermis or outer layer of
skin. They are the most common and the most minor of all burns. The skin is
reddened and extremely painful. The burn will heal on its own without
scarring within two to five days. There may be peeling of the skin and some
temporary discoloration.
-
- Second
degree burns
occur when the first layer of skin is burned through and the second layer,
the dermal layer, is damaged but the burn does not pass through to
underlying tissues. The skin appears moist and there will be deep intense
pain, reddening, blisters and a mottled appearance to the skin. Second
degree burns are considered minor if they involve less than 15 percent of
the body surface in adults and less than 10 percent in children. When
treated with reasonable care, second degree burns will heal themselves and
produce very little scarring. Healing is usually complete within three
weeks.
-
- Third
degree burns
involve all the layers of the skin. They are referred to as full thickness
burns and are the most serious of all burns. These are usually charred black
and include areas that are dry and white. While a third-degree burn may be
very painful, some patients feel little or no pain because the nerve endings
have been destroyed. This type of burn may require skin grafting. As third
degree burns heal, dense scars form.
Determining
the severity of burns
- Source
of the burn - a minor burn caused by nuclear radiation is more severe than a
burn caused by thermal sources. Chemical burns are dangerous because the
chemical may still be on the skin.
-
- Body
regions burned - burns to the face are more severe because they could affect
airway management or the eyes. Burns to hands and feet are also of special
concern because they could impede movement of fingers and toes.
-
- Degree
of the burn - the degree of the burn is important because it could cause
infection of exposed tissues and permit invasion of the circulatory system.
-
- Extent
of burned surface areas - It is important to know the percentage of the
amount of the skin surface involved in the burn. The adult body is divided
into regions, each of which represents nine percent of the total body
surface. These regions are the head and neck, each upper limb, the chest,
the abdomen, the upper back, the lower back and buttocks, the front of each
lower limb, and the back of each lower limb. This makes up 99 percent of the
human body. The remaining one percent is the genital area. With an infant or
small child, more emphasis is placed on the head and trunk.
-
- Age
of the patient - This is important because small children and senior
citizens usually have more severe reactions to burns and different healing
processes.
-
- Pre-existing
physical or mental conditions - Patients with respiratory illnesses, heart
disorders, diabetes or kidney disease are in greater jeopardy than normally
healthy people.
Treatment
of burns
Cool a burn with
water. Do what you must to get cool water on the burn as soon as you can. Go to
the nearest water faucet and turn on the cold spigot and get cool water on the
burn. Put cool, water-soaked cloths on the burn. If possible, avoid icy cold
water and ice cubes. Such measures could cause further damage to burned skin.
Never
apply ointment, grease or butter to the burned area. Applying such products,
actually confine the heat of the burn to the skin and do not allow the damaged
area to cool. In essence, the skin continues to "simmer." After the
initial trauma of the burn and after it has had sufficient time to cool, it
would then be appropriate to put an ointment on the burn. Ointments help prevent
infection.
The one exception to
the "Cool a Burn" method is when the burn is caused by lime powder. In
that case, carefully brush the lime off the skin completely and then flush the
area with water. In the event of any serious burns, call 9-1-1.
