T22.339

Clinical Causes: Contact with hot surfaces or flames Electrical sparks or arcs Fires and explosions Chemical burns involving corrosive substances Contact with molten metals Friction burns combined with heat sources Severe heat exposure during accidents

Key Symptoms: Charred or white, leathery skin Severe pain initially, which may diminish as nerve endings are destroyed Swelling and inflammation in the affected area Possible blistering in surrounding areas (though blisters in third-degree burns are uncommon over the full depth) Loss of sensation in the burn area due to nerve destruction Scarring and possible discoloration Restricted movement or stiffness in the arm

Diagnosis Path: Diagnosis of a third-degree burn involves a thorough physical examination by a healthcare professional. They assess the extent, depth, and location of the burn. In some cases, imaging tests like X-rays or magnetic resonance imaging (MRI) may be used to determine underlying tissue damage or injury to bones and joints. The clinician evaluates factors such as the burn's size, depth, and any associated injuries to plan the appropriate treatment.

Treatment Protocols: Treatment for third-degree burns generally requires specialized medical care, often in a hospital setting. It may include: - **Wound cleaning and debridement** to remove dead tissue - **Skin grafting** to replace damaged tissue with healthy skin from another part of the body - **Surgical procedures** to remove burnt tissue and close wounds - **Pain management**, often involving strong medications - **Infection prevention and control** with antibiotics - **Fluid resuscitation** to maintain blood pressure and hydration - **Long-term rehabilitation**, including physical therapy to regain movement and function Severe burns like these are serious injuries that often involve a multidisciplinary approach for optimal recovery and functional preservation.
