Changes in Parenteral Nutrition During the First Week of Life Influence Early but Not Late Postnatal Growth in Very Low-Birth-Weight Infants.

Background And Aims: Postnatal growth restriction remains a serious problem in very low-birth-weight infants. Enhanced parenteral supply of nutrients as soon as possible after birth is one of the strategies addressed to avoid extrauterine growth restriction. We aimed to analyze changes in growth patterns and in clinical outcomes in our unit after a change in our parenteral nutrition (PN) protocol.
