In brief
In brief
This retrospective study identifies large diaphragmatic defect size and prolonged mechanical ventilation (≥9 days) as independent risk factors for delayed oral feeding in CDH infants. Delayed oral nutrition strongly predicts developmental delay at 18 months, highlighting the need for early feeding intervention and developmental surveillance in high-risk CDH patients.

Abstract
Purpose
To identify risk factors for delayed oral nutrition in infants with a congenital diaphragmatic hernia (CDH) and its impact on developmental delay at 18 months of age.
Methods
This retrospective single-center cohort study compared the clinical parameters in patients with isolated CDH born and treated at our hospital between 2006 and 2020. We evaluated clinical features significantly related to delayed oral nutrition (defined as taking ≥ 30 days from weaning from mechanical ventilation to weaning from tube feeding).
Results
Twenty-six of the 80 cases had delayed oral nutrition. Univariate analyses showed significant differences. Multivariate analyses were performed on the three items of preterm delivery, defect size (over 50% to nearly entire defect), and ventilation for ≥ 9 days. We identified the latter two items as independent risk factors. The adjusted odds ratios were 4.65 (95% confidence interval, 1.27–7.03) and 6.02 (1.65–21.90), respectively. Delayed oral nutrition was related to a significantly higher probability of developmental delay at 18 months (crude odds ratio 4.16, 1.19–14.5).
Conclusion
In patients with CDH, a large defect and ventilatory management over 9 days are independent risk factors for delayed oral nutrition, which is a potent predictor of developmental delay that requires active developmental care.
