Insights
Glycerin laxatives may help preterm infants pass meconium and achieve enteral feeding faster, but evidence on preventing feeding intolerance remains inconclusive for premature neonates.
Area of Science:
- Neonatal Medicine
- Pediatric Gastroenterology
- Clinical Pharmacology
Background:
- Glycerin laxatives are commonly used in neonates for meconium evacuation and to support enteral feeding.
- Systematic review of glycerin laxative effectiveness in this population is lacking.
Purpose of the Study:
- To evaluate the efficacy of glycerin enemas or suppositories in preventing feeding intolerance.
- Focus on preterm infants born at or before 32 weeks' gestational age or weighing ≤1500 g.
Main Methods:
- Comprehensive literature search across major databases (Medline, Embase, Cochrane, Scopus, Web of Science).
- Inclusion of studies assessing glycerin for feeding intolerance in the target neonatal group.
- Quality and evidence level assessment using the AHA's adapted Evidence Evaluation Worksheet.
Main Results:
- Two studies were included, examining meconium evacuation and feeding intolerance.
- One study found no significant difference in meconium passage or time to full enteral feeds.
- The other study indicated shorter times to meconium passage and full enteral feeding, with reduced sepsis rates in the glycerin enema group.
Conclusions:
- Current evidence on the effectiveness of glycerin laxatives for improving feeding tolerance in preterm infants (≤32 weeks GA or ≤1500 g) is inconclusive.
- Further research is needed to definitively establish the role of glycerin in neonatal feeding protocols.
Background:
Glycerin laxatives are often prescribed in the neonatal population for meconium evacuation and to promote enteral feeding. However, the literature regarding their effectiveness has not been systematically reviewed.
Objective:
To assess the effectiveness of glycerin enema or suppository in preventing feeding intolerance in preterm infants at ≤32 weeks' gestational age or weighing ≤1500 g at birth.
Methods:
The Medline, Embase, Cochrane Library, Scopus and Web of Science databases were searched to identify studies that evaluated glycerin enemas/suppositories for feeding intolerance. Using the Evidence Evaluation Worksheet adapted from the American Heart Association's International Liaison Committee on Resuscitation, eligible studies were scored for quality, level of evidence and direction of support.
Results:
Two clinical studies that evaluated meconium evacuation and feeding intolerance were included. One study showed no difference in the time to complete meconium evacuation or establishment of full enteral feeds, while the other showed that the times to first meconium passage and full enteral feeding were significantly shorter, and the rate of sepsis was lower in the glycerin enema group.
Conclusion:
The evidence regarding the effectiveness of glycerin laxatives for improving feeding tolerance is inconclusive in infants at ≤32 weeks' gestational age or weighing ≤1500 g at birth.
