Which factors are associated with increased risk of death from a major burn?

• A. Male; Young; No inhalation injury; Smaller burn size
• B. Female; Elderly; Inhalation injury; Larger burn size
• C. Female; Elderly; No inhalation injury; Smaller burn size
• D. Male; Elderly; Inhalation injury; Smaller burn size

Answer: (B)

Mortality after a major burn is most strongly driven by age, inhalation injury, and the extent of the burn. Elderly patients have less physiologic reserve and more comorbidity, so they’re less able to cope with the systemic inflammatory response, fluid shifts, and organ stress that follow a severe burn. Inhalation injury markedly worsens outcomes by impairing oxygenation, causing airway edema, and increasing the risk of pneumonia and respiratory failure. A larger burn size means a greater metabolic demand, more fluid loss, higher risk of shock, infection, and multi-organ failure. Among the options, the combination that includes elderly status, inhalation injury, and a larger burn size captures the strongest predictors of death after a major burn. The other choices either mix in younger age, omit inhalation injury, or involve smaller burn sizes, which are associated with lower mortality risk.
