ABSTRACTObjectiveThe role of “novel substrates” in neonatal nutrition has generated much interest in recent years. Glutamine has been recognized as a “conditionally essential” amino acid in critically ill adults, particularly for gut and immune function; however, its potential role in the neonate remains unclear. The authors examined the safety and benefits of parenteral glutamine in ill, preterm neonates.DesignRandomized controlled trial.MethodsThirty‐five ill preterm neonates of <1000 g birth‐weight were randomized to receive either glutamine‐supplemented parenteral nutrition (PN) (n = 17) or standard PN (n = 18).ResultsThere were no significant differences in birth‐weight, gestational age, male‐to‐female ratio, or Clinical Risk Index for Babies (CRIB) score between the two groups. During PN there were no significant differences between the groups in white cell count, differential white cell count, blood urea nitrogen, plasma ammonia, lactate, pyruvate, plasma glutamine, or glutamate. The median time to achieving full enteral nutrition (FEN) was shorter in the study group (13 days vs. 21 days, P < 0.05). The number of episodes of culture‐positive sepsis or age at discharge did not differ between groups.ConclusionsParenteral glutamine appears to be well tolerated and safe in the ill, preterm neonate. It may reduce the time to achieving FEN.
