T21.32

Clinical Causes: Contact with hot surfaces, liquids, or flames Electrical burns from electrical outlets or appliances Chemical burns from corrosive substances Explosions or blast injuries Severe accidents involving machinery

Key Symptoms: Loss of sensation in the affected area due to nerve destruction Charred or leathery skin appearance Swelling and discoloration of the skin Severe pain in the initial injury phase, which may diminish as nerve endings are destroyed Possible exposure of underlying tissues such as muscles or bones Signs of infection such as redness, pus, or foul odor

Diagnosis Path: Diagnosis of a third-degree burn involves a physical examination by a healthcare professional, who assesses the extent of tissue damage. The pattern and depth of the burn are identified visually, often supplemented by imaging studies if underlying structures are involved. The extent of the burn is typically measured as a percentage of total body surface area (TBSA) using standardized tools like the Lund and Browder chart. Additional tests may be ordered to evaluate associated injuries or complications.

Treatment Protocols: Management of third-degree burns is comprehensive and usually requires a specialized burn care team. Treatment options include: - **Initial Stabilization:** Ensuring airway, breathing, and circulation are maintained, along with pain management. - **Wound Care:** Removing dead tissue, preventing infection, and protecting the burn area with sterile dressings. - **Surgical Interventions:** Often necessary to remove necrotic tissue (debridement) and perform skin grafting to promote healing. - **Fluid Replacement:** Administering IV fluids to prevent dehydration and maintain blood pressure. - **Infection Control:** Using antibiotics as needed. - **Rehabilitation:** Physical therapy to maintain joint mobility and prevent contractures, along with psychological support. In cases involving extensive burns, long-term rehabilitation and supportive care are critical for recovery.
