Intravenous nutrition for the pediatric patient.
Nutritional management of infants and children differs from that of adults because of the extra requirements for growth and the limitations of physiological immaturity. Although parenteral nutrition (PN) is an accepted practice and a potentially life-saving therapy for pediatric patients who cannot be fed through their gastrointestinal tract, it is associated with the risk of serious metabolic, mechanical, and infectious complications. Candidates for PN should be selected according to well-defined indications, with initial nutritional assessment and with careful attention given to fluid, electrolyte, vitamin, trace element, and caloric requirements. Total calories should be administered so that the nonprotein-calorie to gram-nitrogen ratio is in the range of 150 to 250:1. Although short-term supplemental nutritional support can be administered through a peripheral vein, long-term total PN is best delivered by central venous access. PN should be initiated and monitored in accordance with well-established protocols. The lowest complication rate and highest cost-effectiveness are achieved by an interdisciplinary team that includes one or more nurses, dietitians, pharmacists, and physicians. The development of safe, reliable, and miniaturized intravenous pumps with built-in monitors has made home parenteral nutrition possible and desirable in selected patients.
