[Early nutrition, postnatal growth retardation and outcome of VLBW infants].

Early nutrition is an important determinant of growth, morbidity and psychomotor development in very low birth weight infants. Recent data suggest that "aggressive nutrition" providing early and high protein supply from the first hours of life improves nitrogen balance, reduces postnatal growth retardation, decreases morbidity and is positively related to psychomotor development. This paper will summarize the metabolic bases of this optimal nutrition for preterm infants.
