Enteral feeding of low birth weight infants
1Neonatal Division, Maulana Azad Medical College, New Delhi, India.
Insights
Early enteral feeding for low birth weight (LBW) neonates, including very preterm infants, is supported by evidence. Trophic feeding with human milk within 48 hours improves feeding tolerance without increasing necrotizing enterocolitis risk.
Area of Science:
- Neonatal nutrition
- Pediatric gastroenterology
- Perinatal medicine
Background:
- Low birth weight (LBW) neonates, especially those who are very preterm (< 30 weeks) or sick, require specialized nutritional support.
- Early nutritional interventions are crucial for improving outcomes in vulnerable newborns.
- Establishing adequate enteral feeding is a key challenge in neonatal intensive care.
Purpose of the Study:
- To review the evidence supporting early enteral feeding in low birth weight (LBW) neonates.
- To evaluate the benefits and risks of trophic feeding with human milk.
- To assess methods for advancing enteral feeding volumes and promoting breastfeeding.
Main Methods:
- Review of current scientific evidence on early enteral feeding practices for LBW neonates.
- Analysis of studies investigating trophic feeding protocols and their impact on feeding tolerance.
- Examination of the role of non-nutritive sucking, spoon-feeding, and human milk supplementation.
Main Results:
- Sufficient evidence supports early enteral feeding for LBW neonates, including sick and very preterm infants.
- Trophic feeding with human milk (10-15 ml/kg/day) within 48 hours improves later feeding tolerance without increasing necrotizing enterocolitis risk.
- Gradual increments of 30 ml/kg/day via gavage feeding are supported; non-nutritive sucking aids transition to breastfeeding.
Conclusions:
- Early trophic enteral feeding with human milk is beneficial for LBW neonates, enhancing feeding tolerance and supporting growth.
- Human milk is generally adequate for preterm growth, though supplementation may be needed.
- Further research may clarify the role of human milk fortifiers in promoting growth.
Abstract:
There is sufficient evidence at present to support early enteral feeding of low birth weight (LBW) neonates, including those who are sick or very preterm (< 30 weeks). Trophic feeding with human milk initiated within 48 hours of birth at 10-15 ml/kg/day improves later tolerance to graded increment of enteral feeding volumes without increased risk of necrotizing enterocolitis. Trophic feeding supports increments of feeding volumes by 30 ml/kg/day by intermittent gavage feeding. Non-nutritive sucking and spoon-feeding aid earlier transition to exclusive breast-feeding. Human milk promotes adequate growth of most preterm neonates, though many need multivitamin and mineral supplementation. The role of human milk fortifiers to promote growth appears controversial.
