Growth failure in infants with neonatal abstinence syndrome in the neonatal intensive care unit.

OBJECTIVE: To assess if infants with neonatal abstinence syndrome (NAS) are smaller at birth and have decreased growth parameters between birth and discharge from the neonatal intensive care unit (NICU). METHODS: Retrospective data analysis of term/late-preterm neonates with NAS at a single-center NICU between September 2006 and May 2018. Growth parameters (weight, length, HC) were measured at birth and discharge. Z scores and percentiles were calculated using WHO standard growth curves. RESULTS: A total of 864 infants ≥35 weeks were admitted for NAS. At birth, median percentiles were weight 30%, HC 23%, and length 37%; these decreased significantly (p < 0.001) at discharge to 12%, 6.5%, and 13%, respectively. The percentage of infants <3rd percentile increased significantly (p < 0.001) in all growth parameters from birth to discharge. CONCLUSION: Infants with NAS are smaller at birth and have significant growth retardation in all growth parameters at discharge. An ongoing long-term growth follow-up study will discern the impact of growth restriction in NAS infants.

Assessment of temporal variations in adherence to NRP using video recording in the delivery room.

INTRODUCTION: Video recording and video evaluation tools have been successfully used to evaluate neonatal resuscitation performance. The objective of our study was to evaluate differences in Neonatal Resuscitation Program (NRP) adherence at time of birth between three temporal resuscitative periods using scored video recordings. METHODS: This is a retrospective review of in-situ resuscitation video recordings from a level 3 perinatal center between 2017 and 2018. The modified Neonatal Resuscitation Assessment (mNRA) scoring tool was used as a surrogate marker to assess NRP adherence during daytime, evening, and nighttime hours. RESULTS: A total of 260 resuscitations, of which 258 were births via Cesarean section, were assessed. mNRA composite scores were 86.2% during daytime hours, 87% during evening hours, and 86.6% during nighttime hours. There were no significant differences in mNRA composite scores between any of the three time periods. Differences remained statistically similar after controlling for complexity of resuscitations with administration of positive pressure ventilation (PPV), intubation, or chest compressions. CONCLUSION: Overall adherence to NRP, as measured by composite mNRA scores as a surrogate marker, was high across all three daily resuscitative periods without significant differences between daytime, evening, and nighttime hours.

Prolonging gavage feeds for reduction of gastroesophageal reflux in infants.

OBJECTIVE: To determine if prolonging gavage feedings in infants for ≥60 min is associated with decreased gastroesophageal reflux (GER) compared with bolus feeding using multiple-channel intraluminal impedance with pH probe (MII-pH). STUDY DESIGN: Retrospective analysis of infants who underwent MII-pH between October 2009 and July 2018 and received gavage feedings. Infants were divided into two groups: bolus (<30 min) or prolonged (≥60 min). Symptoms, number of reflux events and percent time pH < 4 was compared. RESULT: Fifty-eight infants underwent evaluation. Thirty-one (54%) received bolus gavage feedings and 27 (46%) received prolonged feedings. Groups differed in postmenstrual age. Total reflux episodes were significantly lower with prolonged feeding (median 19 vs. 28 episodes, p = 0.015), with no difference in acid exposure time. There was no significant difference in GER symptoms between the two groups. CONCLUSION: Prolongation of gavage feedings was associated with decreased total numbers of GER events without reduction in GER symptoms.

Maternal breast milk feeding and length of treatment in infants with neonatal abstinence syndrome.

OBJECTIVE: The objective of this study is to assess whether infants with neonatal abstinence syndrome (NAS), who receive maternal breast milk (BM), have shorter pharmacological treatment durations and lengths of stay compared with formula-fed infants. STUDY DESIGN: Retrospective data analysis from Optum Neonatal Database for infants born between 1 January 2010 and 21 November 2016, who received treatment for NAS. Clinical characteristics and outcomes were compared between infants who received any amount of BM and those exclusively formula-fed. RESULT: Infants (1738) were analyzed. Median length of pharmacological treatment was significantly lower in infants who received any BM (14 days) compared with "no BM" group (17 days, p = 0.04). Similarly, median length of hospitalization was significantly reduced in "any BM" group (19 days vs. 20 days), which remained significant after adjustment for confounders (p = 0.01). There was no difference in hospital re-admission rates. CONCLUSION: Feeding any BM to infants with NAS was associated with both decreased lengths of pharmacological treatment and hospital stay compared with exclusively formula-fed infants.
