Neonatal nutritional requirements and formula composition: a review.

Adequate neonatal nutrition is essential for appropriate growth and avoidance of complications associated with deficiencies. Neonatal nutritional requirements vary with metabolic states, degree of prematurity, and diseases affecting the gastrointestinal, pulmonary, and cardiac systems. Differences exist between formula brands for protein, fat, and carbohydrate sources. Differences also exist between formulas designed for preterm and full-term infants, as well as infants with special nutritional needs. Optimal nutrition should be a consistent goal for each infant, whether in a healthy newborn nursery, intensive-care unit, or home care setting. Nurses must be aware of the possibilities available to address the special needs of infants.
