Burn Emergencies
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.
