Burns are classified into four stages or degrees, each representing increasing severity and depth of tissue damage.
-
First-degree (superficial) burns: These burns affect only the outermost layer of skin, the epidermis. They cause redness, pain, and mild swelling. Sunburn is a common example of a first-degree burn.
-
Second-degree (partial thickness) burns: These burns involve the epidermis and part of the dermis, the layer beneath the epidermis. They result in redness, pain, blistering, and swelling. Second-degree burns are more serious than first-degree burns and may take longer to heal.
-
Third-degree (full thickness) burns: These burns destroy the epidermis and dermis, extending to the underlying subcutaneous fat, muscle, and even bone. They are characterized by a white or charred appearance, little to no pain (due to nerve damage), and a leathery texture. Third-degree burns require skin grafts for healing.
-
Fourth-degree burns: These burns are the most severe and extend through all layers of skin and into underlying tissues, including muscle, tendons, and bone. They are often accompanied by charring and may require amputation or other extensive surgical procedures.
Understanding the different degrees of burns is crucial for appropriate first aid and medical treatment.
