SYNOPSIS
The hypermetabolic response to severe burn injury is characterized by hyperdynamic circulation, profound metabolic, physiologic, catabolic and immune system derangements. Failure to satisfy overwhelming energy and protein requirements after, and during severe burn injury, results in multi-organ dysfunction, increased susceptibility to infection, and death. Attenuation of the hypermetabolic response by various pharmacologic modalities is emerging as an essential component of the management of severe burn patients. This review focuses on the more recent advances in therapeutic strategies to attenuate the hypermetabolic response and its post-burn associated insulin resistance. Modulation of the response by early excision and grafting of burn wounds, environmental thermoregulation, early and continuous enteral feeding with high protein-high carbohydrate feedings and pharmacologic treatments that stimulate anabolism and oppose catabolism have markedly decreased morbidity in the acute phase post severe burn injury.
