Insights
Gastrostomy tubes (G-tubes) are common for infants with congenital diaphragmatic hernia (CDH) facing feeding issues. Survivors with complex hospital stays, ECMO, or PPI use were more likely to receive G-tubes, impacting growth velocity.
Area of Science:
- Pediatric Surgery
- Neonatology
- Gastroenterology
Background:
- Infants with congenital diaphragmatic hernia (CDH) frequently experience feeding difficulties.
- Gastrostomy tube (G-tube) placement is a common intervention for severe feeding issues in newborns.
- Limited data exists on G-tube prevalence and nutritional outcomes in CDH infants.
Purpose of the Study:
- To identify factors associated with G-tube placement in infants with CDH.
- To evaluate the impact of G-tube placement on growth velocity in CDH infants.
Main Methods:
- Retrospective cohort study of CDH infants (1997-2013) at Duke University Medical Center.
- Logistic regression analyzed risk factors for G-tube placement.
- Linear regression assessed associations between growth velocity, G-tube placement, and other risk factors.
Main Results:
- Of 123 CDH infants, 85 survived, with 29% receiving G-tubes.
- Extracorporeal membrane oxygenation (ECMO) and proton pump inhibitor (PPI) use were significantly associated with G-tube placement.
- Infants without G-tubes exhibited a growth velocity 6.5g/day greater than those with G-tubes.
Conclusions:
- CDH survivors with more complex inpatient courses were more likely to receive G-tubes.
- G-tube placement was associated with reduced growth velocity in CDH infants.
- Further research is needed to optimize feeding strategies for CDH patients.
Background:
Gastrostomy tube (G-tube) placement is a common intervention for newborns with severe feeding difficulties. Infants with congenital diaphragmatic hernia (CDH) are at high risk for feeding problems. Prevalence of G-tube placement and consequent nutritional outcomes of infants with CDH and G-tubes has not been described.
Aims:
Determine factors associated with G-tube placement and growth in infants with congenital diaphragmatic hernia.
Study Design:
Retrospective cohort study of infants with CDH to evaluate the association of G-tube placement with risk factors using logistic regression. We also assessed the association between growth velocity and G-tube placement and other risk factors using linear regression.
Subjects:
The subjects of the study were infants with CDH treated at Duke University Medical Center from 1997 to 2013.
Outcome Measures:
Weight gain in infants with CDH that had G-tube placement compared to those infants with CDH that did not.
Result:
Of the 123 infants with CDH, 85 (69%) survived and G-tubes were placed in 25/85 (29%) survivors. On adjusted analysis, extracorporeal membrane oxygenation (OR=11.26 [95% CI: 1.92-65.89]; P=0.01) and proton pump inhibitor use (OR=17.29 [3.98-75.14], P≤0.001) were associated with G-tube placement. Infants without G-tubes had a growth velocity of 6.5g/day (95% CI: 2.5-10.4) more than infants with G-tubes.
Conclusion:
Survivors with more complex inpatient courses were more likely to receive G-tubes. Further investigation is needed to identify optimal feeding practices for infants with CDH.
