Insights
Gastrografin did not speed up meconium passage in premature infants but did improve feeding tolerance and reduce hospital stays. However, it may increase the risk of necrotizing enterocolitis, warranting further research.
Area of Science:
- Neonatalogy
- Gastroenterology
- Clinical Trials
Background:
- Premature infants often experience delayed meconium excretion.
- Feeding intolerance is a significant concern in very low birth weight (VLBW) infants.
Purpose of the Study:
- To investigate the effect of Gastrografin on meconium excretion in VLBW infants.
- To assess Gastrografin's impact on feeding tolerance and hospital length of stay.
Main Methods:
- Stratified, randomized, placebo-controlled trial.
- Involved premature infants (<1500g birth weight, <32 weeks gestational age).
- Administered diluted Gastrografin or placebo within 24 hours of birth.
Main Results:
- No significant difference in time to last meconium passage between groups.
- Gastrografin group showed faster time to full enteral feedings (7.5 days shorter).
- Reduced NICU stay (24 days shorter) and overall hospital stay (17 days shorter).
- Higher incidence of necrotizing enterocolitis (21%) in the Gastrografin group.
Conclusions:
- Gastrografin does not accelerate meconium evacuation.
- Increased stool frequency may benefit feeding tolerance and reduce hospital stay.
- Potential increased risk of necrotizing enterocolitis requires caution.
- Further trials with modified protocols are needed before recommending prophylactic use.
Objective:
To determine whether enteral application of the osmotic contrast agent Gastrografin accelerates complete meconium excretion and improves feeding tolerance in very low birth weight infants.
Methods:
This study was a stratified, randomized, placebo-controlled trial in premature infants with a birth weight <1500 g and a gestational age <32 weeks who received 3 mL/kg Gastrografin diluted 1:3 with water within their first 24 hours of life, or placebo.
Results:
Passage of last meconium occurred after a median of 7 days (95% confidence interval: 6-9 days, n = 39) in the intervention group and after 8 days (95% confidence interval: 7-10 days, n = 39) in the control group (P = .61); however, Gastrografin application was associated with a 7.5-day shorter time to full enteral feedings, a 24-day shorter stay in the NICU, and a 17-day reduction in the overall hospital stay in the intervention group compared with the control group. A numerically higher incidence of necrotizing enterocolitis (21%) was observed in the intervention group, however.
Conclusions:
Gastrografin application did not accelerate meconium evacuation, but the higher stool frequency during the first week of life had a beneficial effect on the time to full enteral feedings and later hospital stay; however, it may increase the necrotizing enterocolitis risk. Further investigations are needed with modified protocols, and the prophylactic use of Gastrografin cannot currently be recommended without further clinical trials.
