EFFICACY AND SAFETY OF TOTAL PARENTERAL-NUTRITION IN PEDIATRIC-PATIENTS

Pediatric patients differ from adult patients because of active musculoskeletal growth and development of visceral organs and because they have a proportionately smaller nutritional reserve, especially premature infants. Measures of outcome of effective nutritional support in pediatric patients who have experienced trauma or medical disease or who have undergone surgical procedures include weight gain, increased height and circumference of the head, increased hepatic synthesis of plasma proteins, immunocompetence, decreased morbidity, improved survival, and fast recovery. If a pediatric patient cannot eat or be tube-fed enterally after 3 days of recovery and support with fluids, parenteral nutrition is indicated. Examples in which this treatment has dramatically decreased morbidity include gastroschisis, short-bowel syndrome, necrotizing enterocolitis, and Hirschsprung's disease. Contraindications to its use include severe congenital (usually genetic) defects and terminal cancer, conditions in which life expectancy and quality of life are severely decreased. The team approach to parenteral and enteral nutrition in pediatric patients is preferred, and stable patients receiving long-term nutritional support, including infants, should be considered for home parenteral nutrition. When administered by protocol, parenteral nutrition is safe in pediatric patients. In properly selected pediatric patients, direct and indirect costs for such therapy may be significantly less than those in adults, and the cost-to-benefit ratio is appreciably higher when life expectancy, parental pleasure, and potential work productivity are considered. Ethical and social issues in initiating and discontinuing parenteral nutrition are best decided during thorough empathic discussions between physicians and parents.
