Purpose: The aim of this study is to examine the tolerability and effect of early high-dose amino acid administration in extremely low birth weight infants (ELBWIs).
Methods: This retrospective cohort study included ELBWI (birth weight <1,000 g, n=142). Biochemical, nutritional, and neurodevelopmental data were compared between infants who received conventional low amino acid (LAA; 1.5 g/kg/day) and those who received high amino acid (HAA; 3 g/kg/day) within the first 48 hours after birth. Neurodevelopmental data included weight, height, and head circumference at discharge, 12 to 14 and 18 to 24 months of corrected age and the Korean Bayley Scale of Infant Development II (K-BSID-II) score at 18 to 24 months of corrected age.
Results: The HAA group demonstrated higher peak plasma albumin (3.0±0.4 vs. 3.2±0.5, P<0.05) and lower serum creatinine (1.7±0.9 vs. 1.4±0.8, P<0.05) during the first 14 days than the LAA group. Full enteral feeding was achieved significantly earlier in infants in the HAA group than in infants in the LAA group (46.2±23.0 days vs. 34.3±21 days, P<0.01). There was no difference between the two groups in the z score changes in all growth indicators from birth to discharge and at 12 to 14 and 18 to 24 months of corrected age, as well as in the K-BSID-II score at 18 to 24 months of corrected age.
Conclusion: Aggressive administration of amino acids during the first 2 days of life in ELBWI was well tolerated and correlated with earlier full enteral feeding, but did not improve growth and neurodevelopment.
