Insights
Early human milk feeding is safe for preterm infants with persistent ductus arteriosus (PDA) treated with indomethacin. This feeding strategy shows good tolerance and comparable outcomes to controls, supporting its use in neonatal care.
Area of Science:
- Neonatal Medicine
- Pediatric Gastroenterology
- Perinatology
Background:
- Early human milk feeding is crucial for preterm infant gut and brain development.
- Persistent ductus arteriosus (PDA) and its treatment with indomethacin can potentially affect enteral feeding tolerance.
- Current practice often continues enteral milk feedings in preterm infants with PDA receiving indomethacin.
Purpose of the Study:
- To evaluate the safety and tolerance of early enteral feeding with human milk in preterm infants treated with indomethacin for PDA.
- To compare feeding outcomes and complications between preterm infants with PDA receiving indomethacin and matched controls.
Main Methods:
- Retrospective study of 64 preterm infants (<29 wk gestational age).
- 32 infants received indomethacin for symptomatic PDA (case group) and 32 were matched controls.
- Comparison of gestational age, body weight, respiratory morbidity, feeding initiation, volumes, gastric residuals, and necrotizing enterocolitis rates.
Main Results:
- No significant differences in the initiation of human milk feeding between case and control infants (median 4.0h vs 5.3h).
- Similar feeding volumes and gastric residuals were observed in both groups during the first 7 days of life.
- The incidence of necrotizing enterocolitis was comparable, with two cases in each group.
Conclusions:
- Early enteral feeding with human milk, initiated within hours of birth, is well-tolerated in preterm infants undergoing indomethacin treatment for PDA.
- This feeding strategy appears as safe and effective as in preterm infants without PDA requiring indomethacin.
- Findings support the continuation of early human milk feeding in this vulnerable population.
Aim:
Early human milk feeding is beneficial for gut and brain development. Persistent ductus arteriosus (PDA) and indomethacin may compromise enteral function in preterm infants. For many years enteral milk feedings have continued in preterm infants receiving indomethacin for PDA. The aim of this study was to investigate whether this strategy is efficient in terms of risks and tolerance to early enteral feeding.
Methods:
This retrospective study included 64 inborn infants of <29 wk gestational age (GA), 32 infants who received indomethacin for symptomatic PDA (case infants) and 32 matched controls. Case infants had a mean (SD) GA of 26.3 wk (1.3) and body weight 839 g (203) versus controls GA 26.4 wk (1.2) and body weight 896 g (213) (p = 0.82 and 0.27, respectively). Case infants had higher respiratory morbidity; 90.6% versus 50% of controls needed mechanical ventilation (p = 0.000).
Results:
Case infants received human milk from a median (range) age of 4.0 h (1.5-27.5), and controls from 5.3 h (2.0-38.0) (p = 0.092). The first dose of indomethacin was given at a mean age of 1.7 d (1.0). There were no differences between the two groups in feeding volumes or gastric residuals on days 1 to 7. Mean (SD) feeding volume on day 7 was 64 ml/kg (31) in case infants and 76 ml/kg (30) in controls (p = 0.23). Four infants developed necrotizing enterocolitis: two case infants and two controls (p = 1.00).
Conclusion:
Early enteral feeding with human milk, starting within the first hours of life, seems to be as well tolerated in preterm infants treated with indomethacin for PDA as in their matched controls.

Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
