Abstract
BACKGROUND:
The purpose of the study was to investigate the impact of gestational age (GA) on short-term neurodevelopmental (ND) outcomes in congenital diaphragmatic hernia survivors.
MATERIALS:
Between 6/2004 and 2/2013, 135 consecutive CDH patients underwent ND assessment using the Bayley Scales of Infant Development-III at a median follow-up age of 13months (range, 5-36). ND delay was defined by a score of ≤85 in any of the composite scales. Severe impairment was defined as a score of ≤69 in at least one domain. The effect of GA was evaluated as continuous and categorical variables. GA at delivery was grouped into full term (39-41weeks), near term (37-3, late preterm (34-36), and preterm (24-33).
RESULTS:
Median GA at delivery was 38weeks (range, 24-41). Fifty (37%) patients were delivered full term, 59 (44%) near term, 16 (12%) late preterm, and 10 (7%) preterm. CDH children born before 39weeks' gestation were more likely to score below average (P=0.005) with corrected age for at least one composite score compared to full term peers. Cognitive (P=0.06) and language (P=0.0 scores tended to be lower in the near-term and late-preterm group compared to full-term CDH infants. Patients born near term and late preterm had significantly lower motor composite and fine motor scores compared to full-term children (P=0.009 and P<0.01, respectively). Preterm children scored the lowest in all composite scales (P<0.05).
CONCLUSIONS:
Compared to term infants, not only preterm but also late preterm and near-term CDH children carry an increased risk of ND delays. Motor performance appears most susceptible to earlier delivery.
