Objective: To compare the effectiveness of nasal continuous positive airway pressure (NCPAP) cycling with continuous NCPAP in the successful weaning of preterm infants of 25(0)-28(6) wk gestation to nasal prongs.
Methods: A total of 30 infants with a gestational age (GA) of 25(0)-28(6) wk, ventilated for respiratory distress syndrome (RDS) and extubated to NCPAP were eligible for the study. They were randomized to NCPAP cycling [Group A: cycling between NCPAP of 4 cm and 1 liter per minute (LPM) of nasal prongs] or to continuous NCPAP at 4 cm of H2O (Group B). Primary outcome was successful weaning off NCPAP to nasal prongs at the end of 72 h of the intervention and remaining off NCPAP for the next 72 h.
Results: The demographic characteristics were similar in both the groups. Infants were randomized to Group A (n = 13) and Group B (n = 17). The primary outcome was not significantly different between the groups (successful weaning to nasal prongs: 31 vs. 41 %; p 0.71).
Conclusions: In this pilot, feasibility study there were no differences in the rates of successful weaning of NCPAP to nasal prongs using either cycling NCPAP or continuous NCPAP in preterm infants. A need exists for a large randomized controlled trial (RCT) to determine the role of cycling NCPAP on neonatal outcomes.
