Overview

A burn is damage to tissues of the body caused by contact with things such as heat, radiation, or chemicals. A third-degree burn damages affects the outer layer of skin (epidermis) and the inner layer of skin (dermis). A child with a third-degree burn needs immediate medical care.

Causes

In most cases, third-degree burns are caused by:

  • Very hot liquids
  • Contact with a hot object
  • Fire
  • Electricity
  • Chemicals

Symptoms

Symptoms can occur a bit differently in each child. Symptoms can include skin that is:

  • Dry and leathery
  • Changes color to black, white, brown, or yellow
  • Swollen
  • Is not painful, because the nerve endings have been destroyed

The symptoms of a third-degree burn can be like other health conditions. Make sure your child sees his or her healthcare provider for a diagnosis.

Diagnosis

The healthcare provider will ask about your child’s symptoms and health history. He or she will give your child a physical exam. The diagnosis of a first-degree burn is based the signs and symptoms, and recent exposure to something that can cause a burn. This may be the sun, something hot, or a chemical.

Treatment

Treatment will depend on your child’s symptoms, age, and general health. It will also depend on how severe the condition is. A child will usually be treated in a hospital unit that specializes in burns. 

Treatment for a third-degree burn will depend on the severity of the burn. Burn severity is determined by:

  • The amount of body surface that is affected
  • Where the burn is located
  • The depth of the burn

Treatment for a third-degree burn may include:

  • Immediate care in an emergency department, possibly in a hospital burn unit
  • Breathing and blood circulation support
  • Intravenous (IV), given into a vein, fluids containing electrolytes
  • Intravenous (IV) or oral antibiotics for infections
  • Cleaning and removal of dead tissue (debridement) from the burn area
  • Antibacterial cream, and other creams
  • Special bandages or dressings
  • Nutritional supplements and a high-protein diet
  • Pain medicines
  • Anti-itch medicines
  • Tetanus vaccine

A large third-degree burn heals slowly. After the burn heals, surgery may be needed. This is done to improve the ability to move, and to remove and repair scarred skin.

In some cases, skin grafting may be needed to close or cover the burn. A skin graft is a piece of healthy skin from one part of the body that is removed and put on an area that needs skin. The burn area that’s covered is called the graft site. The area where a piece of skin is taken is called the donor site. After a skin graft, the donor site looks like a scrape. After a skin graft:

  • A dressing is left on the graft site for a few days before it is changed. The site needs to be still and protected to begin to heal.
  • The donor site usually heals in about 2 weeks.

Complications

Possible complications can include:

  • Infections that may affect any part of the body, such as the lungs
  • Scarring
  • Being unable to move a joint due to scarred tissue (joint contracture)
  • Emotional problems
  • Organ failure and death

The following are some of ways to prevent burns in children:

  • Make sure your hot water heater is set below 120° F (48.8° C).
