title: Perioperative nutrition and metabolism in pediatric patients.
abstract: A developing child, with a high metabolic rate and low body stores of nutrients, is susceptible to metabolic disturbances due to surgical stress. For perioperative nutritional care of infants, the distinct physiologic features of their body fluids must be carefully considered. The postoperative metabolic response is the same as that in adults, but in children this response is more rapid. Based on the urinary excretion of 3-methylhistidine in infants, the postoperative degradation of muscle protein is thought to be twice the preoperative level. This transient increase during the early postoperative period was not suppressed by increased amino acid intake, and energy intake was sufficient. To prevent postoperative metabolic complications, the energy intake of glucose or fat should correspond to the patient's requirements, and excess carbohydrate should be avoided. The quantity and quality of the amino acid formula used must be carefully evaluated.
