Insights
Low-dose oral erythromycin improved feeding tolerance and reduced parenteral nutrition duration in preterm infants over 32 weeks gestation. However, it did not show similar benefits for infants younger than 32 weeks.
Area of Science:
- Neonatology
- Pediatric Gastroenterology
- Pharmacology
Background:
- Feeding intolerance is a common complication in preterm infants.
- Early establishment of enteral feeding is crucial for infant growth and development.
- Parenteral nutrition (PN) is often required but associated with risks.
Purpose of the Study:
- To assess the efficacy of low-dose oral erythromycin in treating feeding intolerance in preterm infants.
- To determine if erythromycin can accelerate the achievement of full enteral feeding.
- To evaluate the impact of erythromycin on the duration of parenteral nutrition.
Main Methods:
- A prospective, double-blind, randomized, placebo-controlled trial was conducted.
- Sixty preterm infants with feeding intolerance were randomized to receive either oral erythromycin (1 mg/kg every 8 h) or placebo.
- Infants were stratified by gestational age (>32 weeks or ≤32 weeks), and outcomes included time to full enteral feeding and duration of PN.
Main Results:
- In infants with gestational age >32 weeks, erythromycin significantly reduced the time to full enteral feeding (10.5 vs 16.3 days) and the duration of PN.
- Erythromycin also led to fewer gastric residuals in infants >32 weeks gestation.
- No significant differences in feeding tolerance or PN duration were observed between erythromycin and placebo groups in infants ≤32 weeks gestation.
Conclusions:
- Low-dose enteral erythromycin effectively improves feeding tolerance and shortens PN duration in preterm infants with gestational age >32 weeks.
- The study did not demonstrate a similar benefit for younger preterm infants (≤32 weeks gestation).
- Further research may be needed to explore erythromycin's role in specific subgroups of preterm infants.
Objectives:
To evaluate the effectiveness of low-dose oral erythromycin to treat feeding intolerance in preterm infants.
Design:
This study was a prospective, double-blind, randomized, placebo-controlled trial on 60 premature infants suffering from feeding intolerance. Thirty infants were given oral erythromycin 1 mg/kg every 8 h and 30 infants were given placebo (normal saline). Randomization was stratified on enrollment according to gestational age whether >32 weeks or
Results:
For infants with gestational age >32 weeks, the erythromycin group achieved full enteral feeding earlier than placebo group (10.5+/-4.1 vs 16.3+/-5.7 days, respectively; P=0.01) had fewer episodes of gastric residuals (P<0.05) and shorter duration of parenteral nutrition (PN) (P<0.05). On the other hand, in infants with gestational age
Conclusion:
Low-dose enteral erythromycin is associated with better tolerance of feeding and shorter duration of PN in infants >32 weeks gestation. A similar effect on younger preterm infants was not demonstrable.
