Fourth, Fifth & Sixth Degree Burns

Burns deeper than third degree receive less attention because they are less common and have historically had mortality rates of nearly 100 percent. Advances in medical technology and better understanding about burns have led to improved chances for victims of burns this deep. Fourth degree burns penetrate entirely through the skin and begin to burn the underlying muscle and ligaments; fifth degree burns penetrate the muscle and begin to burn bone; sixth degree burns are the most severe burns which have charred bone.


Fourth, fifth, or sixth degree burns exhibit many similar symptoms to third degree burns, but with a few additional characteristics. Primarily, these burns result in charring and loss of function of the affected area.

Charring: Charring is a process where exposure to high heat burns the hydrogen and oxygen from the skin, leaving a black substance composed almost entirely of carbon. The presence of char in a burn is indicative that the burn will require grafting and leave scars. Charring is possible in third degree burns, but is more common with deeper burns that have had longer exposure to the heat source.

Loss of Function: These burns also complete destroy the skin’s protective capabilities and begin to damage the underlying muscle. The body does not regrow muscle or bone in the same manner that it regrows skin. Damage to the muscle often requires excision and leads to long-term loss of function of the affected area. Loss of function generally leads to amputation.

Common Causes

Fourth, fifth, and sixth degree burns generally come from the same types of sources that third degrees burns come from. They burn deeper because the victim is exposed to the heat source for an extended duration. A few of the most common sources found in the home or workplace are detailed below.


  • House fires: The U.S. Fire Administration estimates that 3,400 people die every year in home fires in the United States.
  • Cooking accidents: Cooking often involves dealing with extremely hot solids (contact burns) or liquids (scald burns). Hot oil is particularly dangerous and capable of causing deep burns when it is spilled on a victim causing extended contact with the heated liquid.
  • Appliance disrepair: While all electrical sources should be treated with caution, appliances deserve special care. Appliances operate at nearly twice the voltage levels of normal home electrical outlets. Contact with exposed appliance electrical cords has the potential to release substantial amounts of energy into the body.

Work Causes

  • Emergency      Personnel: Home fires are not only dangerous for those living in the home.      Emergency personnel who fight fires are exposed to the dangers of home      fires at a much higher frequency than individuals. Additionally, emergency      personnel often respond to down power lines which pose the danger of      extremely high-voltage burns (in excess of 110 kilovolts).
  • Cable,      Construction, or Electrical Workers: While emergency personnel typically      handle downed power lines, certain professions often work in close      proximity to active power lines on a daily basis.
  • Food Services: Like      cooks in the home, professionals in food services are often exposed to      thermal burn sources. The Center for Disease Control and Prevention      specifically points out the dangers of deep fryers and the possibility of      submerging an extremity into oil that is over 350 °F.
  • Manufacturers,      Medical Workers, and Scientists: The most hazardous chemicals are rarely      seen outside of industrial manufacturing or labs. Even minor contact with      some of these chemicals can be potentially fatal. For example, fluoroantimonic      acid (the most powerful superacid) explodes on contact with water and      releases toxic fumes when not properly contained.


Even with prompt medical treatment, fourth, fifth, and sixth degree burns are often fatal. Burns this severe require immediate medical treatment in order to give the victim the best chances of survival. When a patient is admitted to a burn center with these burns, medical staffs take the following measures:

The first priority is getting the patient stabilized and rehydrated. Burn victims are often dehydrated because of the amount of fluids lost while sustaining the burn and from the wound afterwards. Liquids are usually administered intravenously to get them into the body quickly. Medical staffs also work to stabilize the patient and ensure proper circulation and breathing.

While being stabilized, it is common for the patient to begin receiving antibiotics to prevent infection. Infection is one of the most common complications and can lead to a variety of complications if not treated. Depending on the patient’s condition and the location of the burn, antibiotics are administered orally, intravenously, topically at the site of the burn injury.

While the burn itself may not be painful, patients are often given pain medication because treatment can be painful. Once a patient has been stabilized, excision can begin. Excision, also called debridement, is the process of removing dead and damaged skin from the burn injury. The dead skin is highly susceptible to infection and prevents the body from healing.

Amputation is nearly always required for burns this deep. Amputation is the process of removing part or all of an extremity. Amputation allows medical staffs to control pain and disease. Because these burns cause loss of function, amputation often removes tissue that would not be recoverable in anyhow.

Finally, skin grafts are used to begin the process of re-growing skin in the burned area. The body cannot replace the skin on its own because these burns completely destroy all three layers of the skin, so healthy skin is surgically removed from other areas of the body. If there is not sufficient healthy skin available on the victim, other forms of grafting may need to be used while the patient’s own skin grafts are grown in a lab.
