You can describe burns by their cause: chemical,
electrical, radiation and thermal – or by their depth. The deeper the burn, the more severe it
is. Burns caused by heat (flame, hot
liquid, or contact with hot surface) are the most common. Certain chemicals, however, can also cause
burns. Electrical current can the body
internally as well as externally.
Radiation from the sun can cause sunburn.
A superficial burn first destroys only the top layer
of skin. This is called a first-degree
burn. The skin may appear pink in
color, no blisters present, dry and the burn is usually painful (minor to
moderate). The area may swell. Most sunburns are superficial burns. These superficial burns usually heal in 4 to
6 days without permanent scarring.
If it continues to burn, it injures or destroys the
second layer of skin. This is called a
partial thickness burn or a second degree burn. When burns break the protective layer of skin, they can cause
infection and loss of fluid from the body.
This can damage the body’s ability to control its temperature. Please note that the skin is bright pink to
red and has blisters that may open and seep clear fluid. Consequently, this makes the skin appear
wet. The burned skin may appear mottled
or may appear blotchy (blanches with capillary refill present). These burns are usually painful and the area
often swells. These partial thickness
burns usually heal in 3 to 4 weeks.
Scarring may occur.
Full thickness burns are also called third degree
burns. Third degree burns may initially
appear to be second degree (no blisters, dry/tight/leathery/ brown/tan/waxy or
pearly white, no blanching or capillary refill, pain free, and needs grafting
to heal). Deep burns can also damage
the victim’s ability to breathe. A full
thickness burn destroys all layers of skin and any or all of the underlying
structures – bones, fat, muscles and nerves.
These burns look brown or blackish (charred) with the tissues underneath
sometimes appearing white. They can
either be extremely painful or can sometimes be surprisingly pain-free if the
burn destroys the nerve endings. These
burns are critical.
Critical burns can be life threatening and needs
immediate medical attention. Remember
that it is not always easy to tell how severe a burn is right after it has
happened. Call 9-1-1 or your local
emergency number if a burn survivor: 1). Is having trouble breathing, 2)
Appears to have burns on more than on part of his/her body, 3). Burns on the
head, neck, hands, feet, genitals, perineum or major joints, and 4). Burns
caused by chemicals, explosives, inhalation burns or electricity, 5). Third
degree burns in any age group, and 6). Any survivor with burns and concomitant
trauma (such as fractures) in which the
burn injury poses the greatest risk of morbidity or mortality.
How do you evaluate a burn? The severity depends on: 1). the temperature
of whatever caused the burn, 2). the length of time the victim is exposed to
it, 3). the burn’s location on the body, the size of the burn, 4). the victim’s
age (other than a minor one to a child or an elderly person), and 5). The
victim’s medical condition. Burns
caused by hot flames or grease usually need medical attention, especially if
the victim is a child or elderly. Burns
caused by a hot flames or liquid that contact clothing is also serious. Be aware that the clothing keeps the heat in
contact with the skin. Some fabrics
even melt and stick to the skin. All
these burns may appear minor at first but they can continue to get worse.
To
care for a burn, follow these basic steps.
First, stop the burn process.
Put out the flames or remove the survivor from the source of the burn.
For example, you may have to remove all clothing, diapers, jewelry, belts,
metal and restrictive garments since they can retain heat and cause a
tourniquet-like effect because of changes in the body tissues. If clothing has ignited, use low-pressure
water to extinguish flames or smother the flames with a heavy blanket. After a scald or steam burn or contact with
hot surfaces, flush burn area with low pressure running water to cool the
burned area. Do not use ice except on
minor burns, such as a burned finger from touching a hot stove. After cooling the burned area for several
minutes, cover the burn with a dry, clean dressing to help prevent
infection. Bandage loosely. Do not put any pressure on the burn. Do not put any kind of ointment or massage
therapy lotion on the burn unless it is a very minor burn. Remember that ointments, lotions or oils may
seal in heat and does not do much to relieve pain. Do not use other home or work remedies like butter or grease;
they cause infection. Do not break
blisters; keeping the skin unbroken helps prevent infection.
For
minor burns and burns with open blisters that are not bad enough to need
medical care, wash the area with a bland soap and water. Keep it clean. Leave the wound open or warp with light gauze. Next, put on an antibiotic bland
ointment. Watch for signals of
infection. Repeat cleansing process and ointment twice daily.
Stop the burning. For a serious burn, have someone else if
possible call 9-1-1 or the local emergency number while you provide immediate
care. If you are alone, provide one (1)
minute of first aid care, and then make the call. Have a survivor of severe
burns lie down unless he or she is having trouble breathing. Keep the survivor
comfortable (keeping the survivor from getting chilled or overheated). Do not remove clothing if it is stuck to the
burned soft tissue (skin). Raise burned
areas above the level of the heart, if possible. Remember that burn survivors chill easily, so protect the
survivor from drafts and keep the survivor dry. Please try to obtain the
survivor’s past medical history and tetanus status. Don’t apply ice directly to
any severe burn. Avoid touching a burn
with anything except a clean, dry sterile covering/dressing. Do not try to clean a severe burn. Don’t break blisters. Don’t use any kind of ointment on a severe
burn.
If
a survivor is being held by the source of electrical power: Turn the power off
by removing the fuse for this circuit at the fuse box, or by switching the circuit
breaker to “OFF”. Or – before
attempting a rescue – use a nonconductive item (such as a wooden broom handle)
to move the power source away from the survivor. Again stop the burning process if the clothing has caught fire by
using low-pressure water to put out the flames or smother the flames with a
heavy blanket. Electrical burns can
happen at home, work or on the road (power lines, lightning, defective
electrical appliances, equipment or unprotected electrical outlets). Never go near a survivor until you are sure
that the power is turned off. If a
power line is down, wait for the fire department or the power company. If there are survivors in a car with a
downed wire across or under it, warn them not to move and stay in the car.
Did
you know that with an electrical burn, the burn itself would not be the major
concern? Check breathing and signs of
circulation of the survivor is unconscious.
Check for other injuries like a possible fracture, head, neck or back
injuries. Do not move him/her. Cover an
electrical burn with a dry, sterile dressing/covering. Note that because of the danger of possible
electrocution and the good chance that the burn is deep and that it involves
damaged nerves. The survivor may not
feel pain. Do not cool the burn with
water. Keep the survivor from getting
chilled.
Stop
the burning process by flushing away the liquid chemical agent with a low
pressure running water. A bathroom
shower is ideal. Remove clothing and
jewelry while continuing to flush until EMS arrives. Stay in the shower for 30 minutes to 1 hour. Do not leave for the hospital until the
chemical has been removed or diluted.
Do not use neutralizing agents. Remember the stronger the chemical and
the longer the contact, the worse the burn.
The chemical continues to burn the survivor as long as it is on their
skin. Caution: If only one eye has been affected, flush the
chemically burned eye from the nose outward to prevent washing the chemical
into the unaffected eye.
Brush
off as much of the powder as possible with a brush, gloved hands or a
towel. Flush burn area with plenty of
low-pressure running water.
Flush eyes thoroughly with low-pressure running
water. Hold the survivor’s eyelids
open. Remove contact lenses while
flushing with water. Do not use
neutralizing agents.
