Feeding intervals and fat absorption in preterm babies
1Department of Paediatrics and Child Health, University of Cape Town.
Insights
Continuous nasogastric feeding is as effective as intermittent feeding for preterm infants. This method supports similar weight gain and fat absorption, making it a suitable option, particularly for preventing abdominal distension.
Area of Science:
- Neonatal nutrition
- Gastroenterology
- Pediatric research
Background:
- Preterm infants often require specialized feeding methods.
- Nasogastric (NG) feeding is common, but optimal delivery (continuous vs. intermittent) requires evaluation.
Purpose of the Study:
- To compare the efficacy of continuous nasogastric feeding versus intermittent nasogastric feeding in preterm infants.
- To assess key nutritional and gastrointestinal parameters between feeding regimens.
Main Methods:
- Conducted fat absorption studies on 18 preterm infants (1290-1960g birth weight).
- Employed a randomized crossover design where each infant received evaporated milk via continuous, 1-hourly, 2-hourly, or 3-hourly NG feeding.
- Monitored weight gain, stool transit time, and fat absorption/retention over 3-day periods for each regimen.
Main Results:
- No significant differences in daily weight gain were observed across all feeding methods.
- Stool transit times remained consistent regardless of feeding frequency.
- Fat absorption and retention showed no statistically significant variations between continuous and intermittent NG feeding.
Conclusions:
- Continuous nasogastric feeding is a viable and effective method for preterm infants.
- This feeding strategy supports comparable nutritional outcomes to intermittent feeding.
- Continuous feeding may be particularly advantageous in minimizing abdominal distension in vulnerable preterm populations.
Abstract:
Fat absorption studies were conducted on 18 preterm babies to determine whether continuous nasogastric feeding is as effective as intermittent feeding. The infants ranged from 1 290 g to 1 960 g in birth weight and were assessed at a mean postnatal age of 34 days. Each served as a control by receiving an evaporated milk 1-hourly, 2-hourly, 3-hourly or continuously in random order. Equivalent volumes of milk were ingested over each 3-day period irrespective of the method of feeding and the daily weight gain was similar for the various regimens. Stool transit times did not vary and fat absorption and retention showed no significant differences. Continuous feeding appears to be suitable for preterm babies, especially when there is a need to avoid abdominal distension.
