Burns are tissue injuries caused by heat, chemicals, electricity, or radiation that damage the skin and potentially deeper structures. They are classified by depth (first, second, third, and fourth degree) and severity, with treatment ranging from basic wound care to complex surgical intervention and rehabilitation.
Thermal injury causes protein denaturation and cellular death, leading to increased capillary permeability and fluid loss. The inflammatory response triggers vasodilation, edema formation, and potential systemic complications including hypovolemic shock, infection, and multi-organ dysfunction in severe cases.
Assessment focuses on burn depth, total body surface area affected, and presence of inhalation injury or other trauma. Initial management prioritizes airway protection, fluid resuscitation, pain control, and wound care, while monitoring for complications such as compartment syndrome, infection, and cardiovascular instability.
