Impact of feeding mode on neurodevelopmental outcome in infants and children with congenital heart disease.

OBJECTIVE

To investigate the impact of feeding mode on neurodevelopmental outcomes in children with congenital heart defects.

DESIGN

A retrospective cohort study of 208 children with congenital heart disease (CHD), who had surgery from 1 January 2013 until 31 December 2016 at Texas Children's Hospital, Houston, TX, US.

SETTINGS

University Hospital, Developmental Outcome Clinic.

OUTCOMES MEASURES

Standardized cognitive scores were assessed with Capute Scales and motor development with Revised Gesell Developmental Schedules. We analyzed anthropometrics, mode of feeding, surgical complexity, syndrome, and gender as predictors of developmental outcomes at four time points: hospital discharge, and 6, 12, and 24 months of age.

RESULTS

Mode of feeding is associated with neurodevelopmental outcome in children with CHD. Children on enteral feeding tubes had significantly lower developmental quotient (DQ) scores in cognition, communication, and motor function at 12 and 24 months compared to orally fed children. There were greater proportions of developmental delays (DQ < 70) in enteral tube fed children at the 6, 12, and 24 months visits. Further, there was a strong association between presence of enteral feeding tube, syndrome, and developmental outcome. Greater surgical complexity, weight gain and ethnicity were not associated with the developmental outcomes.

CONCLUSIONS

Our findings suggest that the presence of an enteral feeding tube following corrective congenital heart surgery are at increased risk of neurodevelopmental delays at 12 and 24 months.
