Third-degree burn

A third-degree burn (pronounced: /θɜːrd dɪˈgriː bɜːrn/), also known as a full-thickness burn, is a severe type of burn that destroys the outer layer of skin (epidermis) and the entire layer beneath (dermis). The term "third-degree" signifies that the burn has reached the third layer of the skin. The etymology of the term "third-degree burn" is derived from the burn classification system that categorizes burns based on the severity and depth of the skin damage.

Third-degree burns are characterized by a white or blackened, charred appearance, and the skin may be numb due to damage to the nerve endings in the skin. These burns can result from various causes such as fire, electricity, radiation, chemicals, or hot liquids and objects.

Symptoms

The symptoms of a third-degree burn may include:

Pain (though not always, due to nerve damage)
Skin that appears white, charred, or leathery
Difficulty moving the affected area
Absence of blistering

Treatment

Treatment for third-degree burns usually involves hospitalization. This may include:

Intravenous fluids to prevent dehydration
Pain management
Antibiotics to prevent infection
Skin grafting (transplanting skin from another part of the body)

Prognosis

The prognosis for third-degree burns varies widely depending on the extent of the burn, the patient's overall health, and the promptness of treatment. Complications can include infection, blood loss, shock, and in severe cases, death.

Prevention

Prevention of third-degree burns involves general burn prevention strategies, such as using caution with flammable materials and hot liquids, practicing fire safety, and using sun protection.
