Burn wounds are categorized into different degrees based on their depth and severity:
First-Degree Burns: These burns affect only the top layer of skin (epidermis). They typically cause redness, pain, and mild swelling. Treatment involves the application of topical soothing agents and, if needed, pain relievers.
Second-Degree Burns: These burns extend into the second layer of skin (dermis). They can cause redness, pain, blistering, and swelling. Treatment includes dressings with topical antibiotic creams and ointments. Many second-degree burns heal within 2 to 3 weeks with dressings, leaving minimal scarring. Specialized dressings impregnated with substances like nanocrystalline silver, collagen protein, or antibiotics can help prevent infection and expedite healing. Deeper second-degree burns may require skin grafting if they do not heal with dressings.
Third-Degree Burns: Third-degree burns penetrate through the full thickness of the skin, damaging deeper tissues. They often result in dry, white, or charred skin. Treatment involves surgical procedures to clean the wound, remove dead skin, and then cover the area with skin grafts or flaps.
Fourth-Degree Burns: These are the most severe burns, involving not only the skin but also underlying tissues like muscles and bones. Treatment is similar to that for third-degree burns and often involves extensive surgical interventions.
