Extrauterine growth restriction is an identifiable marker of severe nutritional deficit during the first weeks of life. Nutrition is becoming a key factor not only for the growth of the newborn infants during their hospital stay but also for their long well being. The two strategies, aggressive early PN and minimal enteral nutrition should enhance the overall nutritional health of the preterm infants as evidenced by less postnatal weight loss, an earlier return to birth weight, and improved over all postnatal growth and outcome.
