Absence of postburn hypermetabolism in a group of children with serious burns.
Hypermetabolism proportional to wound size is the expected response in patients who sustain large burns. This metabolic response persists until wound closure is achieved. The value of this response to the injured host remains unproven. Between 1978 and 1991, 104 patients with burns covering 30% or more of the body surface area underwent partitional calorimetry as a component of various research protocols. Thirteen of these patients failed to demonstrate an increase in metabolic rate as compared with a control group. These patients without hypermetabolism were compared with case-matched patients who demonstrated the expected increase in metabolic rate. Although they were not hypermetabolic in response to the burn injury, five of these patients were exposed to a cold stress and were able to increase their metabolic rate appropriately. The failure to mount a hypermetabolic response did not impact the clinical course as measured by survival, length of hospital stay, or maximum weight loss.
