Protein Supplementation in Burn Patients
Severe burn injury over 30% or more of the body surface results in pronounced metabolic response that has prolonged nutritional implications. Understanding the nature of this response and the consequent changes in nutritional requirements is important for the optimal treatment of such patients. The expenditure of resting energy after a burn injury can be as much as 100%. Increased heat loss from the burn wound and increased beta adrenergic activity are probably both important factors that cause an increase in the resting energy expenditure. Burned skin loses its effectiveness as a barrier to water loss, leading to increased evaporative heat loss via the wound. In addition, radiation heat loss is increased from burn wounds. This is brought about by the increased blood supply to the burn wound, which is a normal response to any injury.
