Insights
Transpyloric feeding may help diagnose and manage gastroesophageal reflux-associated apnea in premature infants. This intervention showed significant improvement in most infants studied, aiding in treatment decisions.
Area of Science:
- Neonatology
- Pediatric Gastroenterology
Background:
- Gastroesophageal reflux is a suspected cause of apnea of prematurity, but its role is debated.
- Transpyloric feeding is hypothesized to reduce reflux and aspiration.
Purpose of the Study:
- To investigate the association between transpyloric feeding and a decrease in reflux-related apnea in premature infants.
- To evaluate the diagnostic and therapeutic utility of transpyloric feeding for apnea of prematurity.
Main Methods:
- Retrospective chart review of 41 premature infants on transpyloric feeds.
- Analysis of 15 infants with apnea of prematurity and gastroesophageal reflux.
- Comparison of apnea frequency before and after initiating transpyloric feeds using t-statistics.
Main Results:
- Twelve out of 15 infants (80%) demonstrated a significant reduction in apnea (p <.005) with transpyloric feeds.
- Non-responders were identified within 48 hours.
- Two responders proceeded to antireflux surgery, while nine were discharged without further intervention.
Conclusions:
- Transpyloric feeding appears beneficial for diagnosing and managing gastroesophageal reflux-associated apnea in select premature infants.
- This approach can guide further treatment, including surgery or discharge.
Objective:
The aetiological role of gastroesophageal reflux in apnea of prematurity is controversial. We hypothesized that transpyloric feeds, which decreases reflux and aspiration, will not be associated with decrease in reflux-related apnea.
Study Design:
The shows retrospective chart review of 41 premature babies on transpyloric feeds. Fifteen infants meeting the inclusion criteria of apnea of prematurity and clinical evidence of gastroesophageal reflux were included. Primary data points were number of apneas before and after transpyloric feeds. t-statistics was used for analysis.
Results:
Twelve of the 15 babies showed significant improvement on transpyloric feeds (p <. 005). The nonresponders were identified within 48 h. After discontinuation of transpyloric feeds, 2 responders underwent antireflux surgery and 9 were discharged without further intervention. No transpyloric-tube-related complication was documented.
Conclusion:
Transpyloric feeds may be useful for diagnosis and management of suspected gastroesophageal-reflux-associated apnea in a selected group of infants.

Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals.
