Burn injuries disrupt the skin and lead to fluid loss, infection, scarring and other issues. Burns are classified by depth of tissue destruction as superficial, deep partial thickness, or full thickness. Local burns under 20% TBSA cause local effects while larger burns over 20% TBSA cause systemic responses. Prevention focuses on fire, electrical, chemical and scald safety. Nursing management assesses airway, breathing, circulation, pain and fluid balance, with priorities of maintaining these functions and preventing complications like infection.
