Participant Flow

Recruitment Period: September 2014- August 2015. All participants were recruited from the Neonatal Intensive Care Unit (NICU) at Winthrop University Hospital, Mineola, NY.

Chart review- 26 preterm infants on nCPAP. Weaned off nCPAP before approaching-10. Excluded- 4 (h/o upper airway anomalies, brain injury, etc.). Eligible-12. Declined consent -5. Consented-7. Screening and VFSS completed-7. Analyzed-7. None of the enrolled participants were excluded from the trial before assignment to groups.

Measure
VFSS on nCPAP Then Off nCPAP
Once consented, each participant underwent a video fluoroscopic swallow study (VFSS) while NCPAP was administered via a RAM cannula® (intervention). With the NCPAP turned on each participant was fed room temperature thin liquid barium (Varibar® Thin Liquid Barium Sulfate for Suspension) from a standard bottle (60ml Similac® Volu-Feeder® with an attached Similac® Infant Nipple and Ring (standard flow), a total of 20 swallows were recorded. These swallows were termed "on NCPAP" swallows. The swallows were assessed in real time for any swallowing dysfunction. Immediately following the "on NCPAP" condition, an additional 20 swallows were recorded under VFSS with the NCPAP turned off (intervention). These swallows were termed "off NCPAP" swallows.

Once consented, each participant underwent a video fluoroscopic swallow study (VFSS) while NCPAP was administered via a RAM cannula® (intervention). With the NCPAP turned on each participant was fed room temperature thin liquid barium (Varibar® Thin Liquid Barium Sulfate for Suspension) from a standard bottle (60ml Similac® Volu-Feeder® with an attached Similac® Infant Nipple and Ring (standard flow), a total of 20 swallows were recorded. These swallows were termed "on NCPAP" swallows. The swallows were assessed in real time for any swallowing dysfunction. NCPAP: Does NCPAP induce dysphagia in neonates? Each baby will be evaluated for dysphagia (using fluoroscopy) while on NCPAP and off NCPAP. Varibar® Thin Liquid Barium Sulfate for Suspension: Liquid barium is used as a contrast material to allow visualization of swallowed boluses under fluoroscopy.
