Insights
Rapid passage of meconium is crucial for feeding tolerance in extremely low birthweight (ELBW) infants. Delayed meconium evacuation negatively impacts feeding volumes in the early days of life.
Area of Science:
- Neonatalogy
- Pediatric Gastroenterology
Background:
- Early enteral nutrition is vital for extremely low birthweight (ELBW) infants.
- Feeding tolerance is a critical factor in the management of ELBW infants.
Purpose of the Study:
- To investigate the correlation between meconium passage timing and feeding tolerance in ELBW infants.
- To assess the impact of first and last meconium passage on enteral feeding volumes.
Main Methods:
- A cohort of 41 ELBW infants was studied.
- Standardized enteral feeding protocol initiated on day 3.
- Linear regression analysis used to evaluate the relationship between meconium timing and feeding volume at day 14.
Main Results:
- No significant correlation was found between the timing of the first meconium and feeding volume.
- A significant correlation (p < 0.001) was observed between the timing of the last meconium and feeding volume.
- Infants with last meconium passage within 6 days had higher feeding volumes compared to those with delayed passage.
Conclusions:
- Rapid evacuation of meconium is a key factor for feeding tolerance in ELBW infants.
- Further research is needed to explore methods for accelerating meconium passage and its effect on feeding tolerance.
Unlabelled:
The aim of this study was to evaluate the correlation between the timing of the first and last meconium and feeding tolerance in the very early enteral nutrition of extremely low birthweight (ELBW) infants. Forty-one ELBW infants were fed following a standardized protocol (day 3-14). At 48 h of age bolus gavage feeding with milk was started (12 ml kg(-1) d(-1) increments, 12 meals per day). Gastric residuals up to 2 ml or up to 3 ml were tolerated in infants with a birthweight of < or = 750 g or > 750 g, respectively. No enemas or laxatives were given during the study. The impact of the time until the passage of the first (M-1) and last (M-last) meconium on the feeding volume on day 14 (V14) was evaluated by linear regression analysis. Data are presented as median (range). M-1 was 31 h (0.5-77 h), M-last was 6 d (1.4-22 d) and V14 was 99 (0-156) ml kg(-1). V14 increased with decreasing M-last (p < 0.001) but there was no correlation between V14 and M-1. V14 was 112 (0-156) ml kg(-1) if M-last was shorter than 6 d and 37 (0-147) ml kg(-1) if M-last was longer than 6 d.
Conclusion:
Rapid meconium evacuation appeared to be a key factor for the feeding tolerance of ELBW infants during the first 14 d of life. Further studies needed to investigate whether meconium passage can be accelerated and whether acceleration of the meconium passage will improve the early feeding tolerance in ELBWW infants.
