title: Effect of Nasal Continuous Positive Airway Pressure (NCPAP) Cycling and Continuous NCPAP on Successful Weaning: A Randomized Controlled Trial.
abstract: 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.
