or full-thickness burns, are the most serious type of burn. They involve all the layers
of the skin
and underlying tissue and can cause permanent damage.
More to Know
Third-degree burns are most often caused by direct extended contact with fire,
heated objects, steam, hot liquids, chemicals, or electrical currents.
With a third-degree burn, the surface of the skin is swollen and looks dry, waxy
white, leathery, brown, or charred. There may be severe pain — or, little or
no pain because of nerve damage. Some burn victims go into shock.
If someone suffers a third-degree burn, call
911 immediately. Make sure he or she is in a safe place but don't remove burned
clothing. Apply cool water over the area for at least 3-5 minutes, then cover the
area with a clean dry cloth or sheet until help arrives. If possible, elevate the
burned body part(s) above the level of the heart.
Once at the hospital, treatment may include cleaning the affected area and removing
dead skin and tissue; antibiotics given orally (taken by mouth), topically (applied
to the skin), or intravenously (IV) (through the veins); intravenous (IV) fluids;
and pain medicine.
Often, doctors do a skin graft — a type of surgery where healthy skin is
taken from an unburned part of the body and placed on the wound to help it heal.
Keep in Mind
Third-degree burns are a serious medical emergency and can be life threatening.
If treated quickly, however, many burn cases can have good outcomes.
