Early parenteral nutrition in neonates with congenital diaphragmatic hernia.

Abstract

The ideal nutritive strategy for a neonate with congenital diaphragmatic hernia (CDH) has not been elucidated. The purpose of this study was to investigate the efficacy of early parenteral nutrition (PN) in CDH neonates. Thirty-five CDH neonates admitted to a single hospital from January 2005 to December 2014 were retrospectively reviewed. For the first 4 years of the study period, neonates received non-early PN (n-EPN) (2005-2008, amino acids [AA] <1.0g/kg/day, no lipids administered). After the transitional period (TP) (2009-2011, AA 1.0-2.5g/kg/day, lipid 1.0g/kg/day), early PN (EPN) (2011-2014, AA ≥3.0g/kg/day, lipid 1.0g/kg/day) was performed. We investigated the clinical effect of PN for growth-associated clinical variables and the outcomes. The first day of AA administration was late in the n-EPN period (6.0 ± 4.6, 0.0 ± 0.8, 0.1 ± 0.3 ; n-EPN, TP, EPN: in order). The final day of PN (11.0 ± 3.7, 9.2 ± 4.0, 12.4 ± 3.9) and the first day of enteral feeding (4.5 ± 1.9, 4.3 ± 1.4, 4.5 ± 3.2), the first day of full milk feeding (100 mL/kg/day) (10.8 ± 5.4, 9.2 ± 2.3, 11.5 ± 3.5) were statistically equal in every period. The date and body weight at discharge showed no significant differences among the three groups, but the weight-gain rate from birth to discharge was higher in the EPN group than in the n-EPN group (P = 0.023). The rate of inhaled nitric oxide (NO) gas administration and the duration of ventilation showed no significant differences among the three groups. Severe PN-associated liver disease was not noted during the observation period. Early PN for CDH neonates promotes weight gain in the neonatal intensive-care unit. The long-term efficacy and safety of EPN for CDH neonates should be elucidated by additional studies.
