Brief Summary

Bronchopulmonary dysplasia (BPD) is the most common complication of extreme preterm birth. It impacts 10,000-15,000 infants in the US annually, including approximately 50% of infants with birth weight \< 1000g. BPD is associated with multiple long-term adverse outcomes including chronic cardiopulmonary and neurodevelopmental impairments. Infants with severe BPD, defined as a need for ≥ 30% inspired oxygen and/or mechanical respiratory support at 36 weeks postmenstrual age (PMA), suffer the greatest burden of these chronic sequelae. Recurrent episodes of hypoxemia and prolonged exposure to supplemental oxygen are linked to the development of these impairments. Gastroesophageal reflux (GER) contributes to these mechanisms by exacerbating pulmonary inflammation and inducing bronchospasm. Unfortunately, clinically available methods to diagnose GER in infants are unreliable. Moreover, acid suppressive agents are both ineffective and carry high risk of serious life-threatening morbidity. Simple transpyloric feeding has promise, but has not been evaluated in BPD. This study will pilot N-of-1 trials to assess whether transpyloric feeds reduce airway complications of GER and and whether this methodology can aid in identifying individual infants with severe BPD who are likely to benefit from prolonged use of transpyloric feeds. Aim 1. To determine for each enrolled infant with severe BPD whether transpyloric compared to gastric feeds reduce the number of daily intermittent hypoxemic events (primary outcome) and improve a validated BPD severity score (secondary outcome). The investigators hypothesize that 80% percent of enrolled infants will have significantly fewer daily intermittent hypoxemic events with transpyloric compared to gastric feeds and will have this feeding method formally recommended. Aim 2. To pool results from multiple N-of-1 trials to determine whether transpyloric compared to gastric feeds reduce airway complications of GER in infants with severe BPD. The investigators hypothesize that transpyloric compared to gastric feeds will be associated overall with a 15% reduction in number of daily intermittent hypoxemic events.
