Insights
Continuous feeding significantly improves gastrointestinal tolerance and growth in very low birth weight (VLBW) infants compared to intermittent feeding methods. This approach helps VLBW infants reach full enteral feeding faster, especially the smallest ones.
Area of Science:
- Neonatal Nutrition
- Pediatric Gastroenterology
- Premature Infant Care
Background:
- Optimizing nutrition is critical for the growth and development of very low birth weight (VLBW) infants.
- Gastrointestinal tolerance and feeding methods significantly impact outcomes in premature neonates.
Purpose of the Study:
- To compare the efficacy of continuous versus intermittent feeding strategies.
- To evaluate the impact on gastrointestinal tolerance and growth in VLBW infants.
Main Methods:
- A randomized controlled trial involving 70 premature infants (gestational age 24-29 weeks, birth weight < 1200 g).
- Infants were assigned to continuous nasogastric, intermittent nasogastric, or intermittent orogastric feeding.
- Key outcomes included time to full enteral feeding, growth rates, and enteral intolerance.
Main Results:
- Continuous feeding led to significantly faster achievement of full enteral feeding (HR = 1.86).
- The benefit was more pronounced in infants with birth weight ≤ 850 g (adjusted HR = 4.13).
- Continuously fed infants exhibited significantly faster growth rates (P = .002).
Conclusions:
- Continuous feeding appears superior to intermittent feeding for VLBW infants.
- This method enhances gastrointestinal tolerance and promotes better growth in premature neonates.
Objective:
To compare the effects of continuous versus intermittent feeding on gastrointestinal tolerance and growth in very low birth weight (VLBW) infants.
Study Design:
In a randomized, controlled trial conducted at 3 neonatal units, 70 premature infants with a gestational age 24 to 29 weeks and birth weight < 1200 g were assigned to 1 of 3 feeding methods: continuous nasogastric feeding, intermittent nasogastric feeding, or intermittent orogastric feeding. Feeding was initiated within 30 hours of birth. Daily enteral and parenteral volumes, caloric and protein intakes, growth, enteral intolerance, and clinical complications were recorded. Cox regression analysis was used to determine primary outcome, the time to achieve full enteral feeding.
Results:
The continuously fed infants achieved full enteral feeding significantly faster than the intermittently fed infants (hazard ratio [HR] = 1.86; 95% confidence interval [CI] = 1.07 to 3.22). In stratified analysis according to birth weight, the improvement was even more pronounced in the smallest infants, those with birth weight < or = 850 g (adjusted HR = 4.13; 95% CI = 1.48 to 11.53). Growth rate was significantly faster in the continuously fed infants ( P = .002).
Conclusion:
In VLBW infants, continuous feeding seems to be better than intermittent feeding with regard to gastrointestinal tolerance and growth.
