Feeding practices and growth of infants with Pierre Robin Sequence.

OBJECTIVES

To assess the impact of feeding practices on growth in infants with Pierre Robin Sequence (PRS) during their inpatient stay in a neonatal intensive care unit in a large tertiary paediatric hospital setting.

METHODS

A retrospective review of feeding practices in infants with PRS was conducted between January 2006 and September 2017. Baseline demographics, nutrition-related and general outcomes were collected. Feeding difficulties, length of stay (LOS) and malnutrition were the primary outcome measures. Feeding difficulties included absence or poor-quality suck, episodes of aspiration, use of proton pump inhibitors or multiple episodes of vomiting. Malnutrition was classified as a weight-for-age Z score of < -1.

RESULTS

Analysis was conducted on 49 infants with PRS that met eligibility criteria. Feeding difficulties correlated with a longer LOS (24.1 vs 6.8 days (p = 0.001)) Z-scores differed significantly between birth and discharge (0.21(1.84) vs -1.27(2.14)) (p < 0.001*) with malnutrition being evident in 26 infants of which only 17 infants were seen by a dietitian. Presence of intrauterine growth restriction (IUGR) increased the likelihood of malnutrition (OR 1.40(CI-1.11-1.77)).

CONCLUSION

Infants with PRS are highly likely to have feeding difficulties and malnutrition. Early intervention by a dietitian is recommended to reduce the impacts of feeding difficulties, meet elevated energy requirements and facilitate growth. Infants with a longer inpatient stay or presence of IUGR should have their growth and feeding routinely monitored.
