Insights
Nasogastric tube feeding in preterm infants is faster for establishing enteral nutrition compared to orogastric tube feeding. Further research is needed to assess adverse outcomes associated with different feeding routes.
Area of Science:
- Neonatal care
- Pediatric nutrition
- Gastroenterology
Background:
- Enteral nutrition delivery in preterm infants utilizes nasogastric (NG) or orogastric (OG) tubes.
- Both NG and OG routes present distinct advantages and disadvantages.
- Comparative analysis of these feeding methods is crucial for optimizing infant care.
Purpose of the Study:
- To compare the efficacy of NG versus OG tube feeding in preterm infants.
- To evaluate the impact of feeding route on infant growth and development.
- To assess the incidence of adverse outcomes associated with NG and OG tube feeding.
Main Methods:
- Meta-analysis of randomized controlled trials (RCTs).
- Searched major databases: PubMed, Embase, Web of Science, Cochrane Central.
- Assessed risk of bias using Cochrane tool v2; data analysis with Review Manager 5.4.
Main Results:
- Included 6 studies with 265 preterm infants.
- Orogastric tube feeding significantly delayed time to full enteral feeding (MD = 1.62, p < 0.01).
- No significant difference in time to regain birth weight; insufficient data on adverse events.
Conclusions:
- Nasogastric tube feeding facilitates quicker establishment of full enteral feeding in preterm infants compared to orogastric.
- Further investigation is necessary to fully understand the impact of feeding routes on adverse events.
Background:
Enteral nutrition can be delivered to the stomach using nasogastric or orogastric tubes, with each route having advantages and disadvantages. This meta-analysis aimed to compare the effects of these methods on growth, development, and the incidence of adverse outcomes.
Methods:
This analysis included studies that enrolled preterm infants who received nasogastric or orogastric tube feeding. We searched databases including PubMed, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials. Only randomized controlled trials were selected. We used version 2 of the Cochrane tool to assess the risk of bias in randomized trials and Review Manager 5.4 software to perform the meta-analysis.
Results:
Six studies involving 265 preterm infants were included. The meta-analysis showed that orogastric tube feeding took significantly longer to establish full enteral tube feeding compared to nasogastric tube feeding (MD = 1.62, 95% confidence interval [CI]: 0.99-2.26, Z = 5.02, p < 0.01). However, no significant difference was observed between the two groups regarding time to regain birth weight (MD = -0.38, 95% CI: -2.2-1.44, Z = 5.02, p = 0.68). Data on adverse events were insufficient to perform a combined analysis.
Conclusions:
Preterm infants fed via nasogastric tubes took less time to reach full enteral feeding than those fed via orogastric tubes. Further research is required to evaluate the effect of feeding routes on adverse outcomes.
