Insights
Probiotics significantly reduced feeding intolerance in low birth weight (LBW) premature infants. This safe intervention also promoted weight gain and faster enteral nutrition, improving outcomes for vulnerable newborns.
Area of Science:
- Neonatal Medicine
- Microbiology
- Gastroenterology
Context:
- Feeding intolerance is a common complication in low birth weight (LBW) premature infants, leading to delayed growth and increased hospital stays.
- Early administration of probiotics is being explored as a strategy to mitigate gut-related issues in neonates.
- Understanding the specific benefits and safety of probiotics in this vulnerable population is crucial for clinical practice.
Purpose:
- To evaluate the efficacy and safety of probiotic supplementation for preventing feeding intolerance in low birth weight (LBW) premature infants.
- To compare key clinical outcomes, including time to regain birth weight, time to full enteral nutrition, and length of hospitalization, between infants receiving probiotics and those receiving conventional treatment.
Summary:
- A randomized controlled trial involving 60 LBW premature infants demonstrated that probiotic administration (0.25 g twice daily) significantly reduced the incidence of feeding intolerance compared to conventional treatment (4% vs. 14%).
- Infants in the probiotic group achieved their birth weight and full enteral nutrition faster (6.8 vs. 7.7 days and 8.0 vs. 9.0 days, respectively).
- No adverse reactions were reported in the probiotic group, indicating a favorable safety profile.
Impact:
- Probiotic supplementation offers a safe and effective strategy to reduce feeding intolerance in LBW premature infants.
- This intervention can accelerate infant growth and shorten the duration of hospitalization, potentially improving long-term neurodevelopmental outcomes.
- These findings support the integration of probiotics into standard care protocols for LBW premature infants to enhance gastrointestinal health and overall development.
Objective:
To study the efficacy and safety of probiotics for the prevention of feeding intolerance in low birth weight (LBW) premature infants.
Methods:
Sixty eligible LBW premature infants were randomly divided into probiotics and conventional treatment groups (n=30 each). Both groups received treatment of the primary disease. Additionally, the probiotics treatment group was administered with probiotics (0.25 g, twice daily). The incidence of feeding intolerance, the time to regain birth weight and to reach full enteral nutrition and the length of hospitalization were compared between the two groups. The occurrence of adverse reactions was recorded.
Results:
The incidence of feeding intolerance in the probiotics treatment group was lower than that in the conventional treatment group (4% vs 14%; P<0.01). The time to regain birth weight (6.8±1.2 days vs 7.7±1.6 days; P<0.05) and the time to reach full enteral nutrition (8.0±1.4 days vs 9.0±2.0 days; P<0.05) in the probiotics treatment group were shorter than those in the conventional treatment group. No adverse reactions were observed in the probiotics treatment group.
Conclusions:
Probiotics can reduce the incidence of feeding intolerance in LBW premature infants, can promote weight gain and shorten the time to reach full enteral nutrition. The application of probiotics appears to be safe in LBW premature infants.
