Insights
Establishing a normal bowel habit in very premature infants is key to achieving full enteral feeding. Earlier feeding tolerance is linked to improved growth outcomes, reducing postnatal growth failure.
Area of Science:
- Neonatalogy
- Pediatric Gastroenterology
- Infant Nutrition
Background:
- Very premature infants (<28 weeks gestational age) often experience feeding difficulties.
- Establishing enteral feeding is crucial for growth and development in this vulnerable population.
- Bowel habit development is a potential indicator of gastrointestinal maturity and feeding tolerance.
Purpose of the Study:
- To investigate the association between achieving a normal stooling pattern and the attainment of full enteral feeding.
- To determine if earlier normalization of bowel habits impacts the time to full enteral feeding.
- To assess the relationship between timely full enteral feeding and infant growth.
Main Methods:
- Prospective observational study of 121 infants with gestational age <28 weeks.
- Standardized protocol for rectal stimulation and enemas for infants with abdominal distension and no defecation.
- Defined age of normal bowel habit (T-NBH) and time to full enteral feeding (T-120); used multivariable linear regression.
Main Results:
- The median age for normal bowel habit (T-NBH) was 16 days, and the median time to full enteral feeding (T-120) was also 16 days.
- Earlier T-NBH was significantly associated with earlier T-120 (r=0.625, P<0.0001).
- Earlier achievement of full enteral feeding correlated with a less pronounced decrease in weight z-score (r=-0.446, P<0.0001).
Conclusions:
- Normalization of bowel habit is a critical factor in achieving full enteral feeding in very immature infants.
- Early establishment of full enteral feeding is associated with reduced postnatal growth failure.
- Monitoring bowel habit can inform strategies for optimizing nutrition and growth in extremely preterm infants.
Objective:
The objective of this study was to determine whether acquisition of normal stooling pattern is associated with full enteral feeding and growth.
Study Design:
This is a prospective observational study of infants with a gestational age of <28 weeks (n=121). All infants admitted to our unit during the study period were managed using the same protocol for rectal stimulation and enemas: we used rectal stimulation if abdominal distension and no defecation occurred in the previous 24 h; enema administration was practiced if abdominal distension persists and no defecation had occurred after rectal stimulation. Age of normal bowel habit (T-NBH) is defined as days when two stools passed each day without enemas or stimulation for three consecutive days. Full enteral feeding is measured by time to receive 120 mL/kg/day (T-120). Multivariable linear regression estimated the contribution of T-NBH on T-120 and the effect of tolerance on growth.
Results:
T-NBH was 16 days (12, 24 days) and T-120 was 16 days (12, 24 days). T-120 decreased with earlier normal bowel habit (r=0.625, P<0.0001). Change in weight z-score between 36 weeks postmenstrual age and birth was less pronounced with earlier full enteral feeding (r=-0.446, P<0.0001).
Conclusion:
Normalization of bowel habit is an important determinant of full enteral feeding of very immature infants. Earlier full enteral feeding is associated with less postnatal growth failure.
