Burn injury results in a sustained hypermetabolic state with resulting increased caloric and protein requirements to support the stress and immune responses; augmented protein, fat, and carbohydrate catabolism; oxidative stress; and exudative losses. Along with surgical debridement, nutrition and resuscitation are the foundations of patient management after severe burn injury. Recent literature has demonstrated a clear benefit to early enteral nutrition initiation during the resuscitation period. This review aims to examine recent literature discussing both physiologic impact of burn injury and approaches to feeding during resuscitation after burn injury; including methods of determining nutrition requirements, routes, timing, and monitoring response and the associated benefits and consequences thereof.
