Understanding Burn Degrees- A Guide to Severity and Treatment

Degrees of burns on the skin are typically classified based on the severity of tissue damage. The most commonly used classification system divides burns into three main categories: first-, second-, and third-degree burns (Saladin, 2021). First-degree burns are the mildest form of burns and typically affect only the outer layer of the skin, known as the epidermis (Saladin, 2021). Symptoms include redness, pain, and mild swelling. First-degree burns usually heal within a few days and rarely cause scarring. An example of a first-degree burn is a sunburn.

Subsequently, second-degree burns affect both the outer layer (epidermis) and the underlying layer (dermis) of the skin (Saladin, 2021). Symptoms include redness, pain, swelling, and blistering. These burns can be more painful than first-degree burns and may take several weeks to heal. If properly cared for, second-degree burns typically do not cause scarring, but they may leave pigment changes in the skin. Third-degree burns are the most severe and involve damage to all layers of the skin, as well as potentially deeper tissues such as muscles, tendons, and bones, hence the term full thickness burns (Saladin, 2021). Symptoms may include charred or white skin, numbness due to nerve damage, and a leathery or waxy appearance.

Third-degree burns often require medical attention, including skin grafting, to promote healing and prevent complications. Failure to treat these burns leads to contracture (abnormal connective tissue fibrosis) and severe disfigurement. Notably, third-degree burns tend to be painless because of the severe damage done to the nerves; however, the area surrounding the burnt part can still feel pain (Saladin, 2021). The leading causes of death in burn victims include wound infection, septicemia, circulatory shock, and cardiac arrest, caused by massive loss of blood plasma from the wounds (Tiwari, 2012). Scarring is common with third-degree burns, and extensive rehabilitation may be necessary to regain function and mobility in affected areas. It is important to note that there are also variations within these categories, such as superficial and deep second-degree burns, as well as fourth-degree burns that extend into deeper tissues beyond the skin.

Initial Post Instructions
This week, we are learning about the structure and function of the skin. Now let’s turn our attention to diseases and abnormalities that can arise in the integument. For your initial post address one of the following topics:

Discuss how skin contributes to the maintenance of homeostasis.
Discuss types of skin cancers.
Discuss degrees of burns.
