Background: A multicentre RCT (Ref) completed in 2009 showed that taking preterm infants (PIís) off CPAP once reaching stability criteria significantly reduced CPAP weaning time, CPAP time, oxygen requirement and CLD and length of admission. However, taking these babies off CPAP earlier may have a detrimental affect on time to full feeds, cessation of caffeine and weight gain.
Methods: Post hoc analysis of a multicentre RCT of PIís <30 weeks gestation that compared three different CPAP weaning methods (M1: taken off with the intention of staying off; M2: cycled gradually off; M3: cycled off gradually and with low flow oxygen during cycling off periods). Using generalised linear models with repeated measures and Tweedie model with a log link function these CPAP weaning methods were compared in terms of their effects on: 1. Time to reach full enteral feeds 2. Time to cease caffeine 3. Weight gain over 18 weeks.
Results: 177 PIís were recruited from April 2006 to October 2009. Data was available from 174 PIís. Baseline characteristics are shown in the Table. There were no significant differences in corrected gestational age (CGAĪ1SD) at full feeds, caffeine cessation (Table) or weight gain trends or predicted weight gain between the three methods (data not shown).

Conclusion: Despite coming off CPAP earlier: time to reach full enteral feeds, time to cease caffeine and weight gain were not affected.
