Insights
A rapid enteral feeding strategy is safe for very low birth weight (VLBW) infants. This approach significantly reduces hospital stay and parenteral nutrition duration without increasing intestinal morbidity.
Area of Science:
- Neonatalogy
- Pediatric Gastroenterology
- Clinical Nutrition
Background:
- Enteral feeding is crucial for infant growth and development.
- Optimizing feeding strategies in very low birth weight (VLBW) infants is essential to minimize complications.
Purpose of the Study:
- To evaluate the safety and impact of a standardized rapid enteral feeding strategy on intestinal morbidity in VLBW infants.
- To compare outcomes between infants receiving slow versus rapid enteral feeding regimens.
Main Methods:
- Retrospective cohort study of 301 inborn VLBW infants.
- Comparison of intestinal morbidity (necrotizing enterocolitis, intestinal perforation) between slow (10 ml/kg/day increase) and rapid (20 ml/kg/day increase) feeding groups.
- Statistical analyses including univariate and multivariable logistic and linear regression.
Main Results:
- No significant difference in intestinal morbidity between slow and rapid feeding groups (p=0.25).
- No significant difference in all-cause mortality or late-onset sepsis.
- Significantly shorter length of hospital stay (HS) and duration of parenteral nutrition (PEN) in the rapid feeding group (HS: -8.35 days, PEN: -7.13 days).
Conclusions:
- A rapid enteral feeding strategy is safe for VLBW infants.
- Implementation of rapid enteral feeding can lead to reduced hospital stay and parenteral nutrition duration.
- This strategy offers potential benefits for resource utilization and infant recovery.
Purpose:
To investigate the association of a standardized rapid enteral feeding strategy (established in 2011 in our unit) with intestinal morbidity in very low birth weight (VLBW) infants.
Methods:
A total of 301 inborn VLBW infants were included in this single-centre retrospective cohort study. We compared the incidence of intestinal morbidity (defined as necrotizing enterocolitis or intestinal perforation) in slowly enterally fed infants in 2008-2010 (10 ml/kg/day increase of milk feeds) to a corresponding cohort of rapidly enterally fed infants in 2011-2013 (20 ml/kg/day increase of milk feeds). Univariate and multivariable logistic and linear regression analyses, respectively, were performed to control for confounding variables.
Results:
Both groups were similar regarding baseline demographic and perinatal characteristics. In univariate modeling, intestinal morbidity did not significantly differ between the two groups (p = 0.25), neither did all-cause mortality nor incidence of late onset sepsis in multivariable modeling. In contrast, length of hospital stay (HS) and duration of parenteral nutrition (PEN) were significantly shorter in the rapid group (HS: -8.35 days, p = 0.012 and PEN: -7.13 days, p < 0.001).
Conclusions:
Implementation of a more rapid enteral feeding regime is safe in VLBW infants and may significantly shorten length of HS and PEN in this cohort.
