'Propped and prone' positioning reduces respiratory events in spontaneously breathing preterm infants: A randomised triple crossover study

Aim We compared effects of infant positioning and feed-rate interventions on respiratory events and oximetry parameters in spontaneously breathing preterm infants born A randomised triple crossover design was employed. n = 68 infants underwent three test conditions A: control (supine/flat, gravity bolus feeds), B: position intervention (propped/prone) and C: feed-rate intervention (continuous pump feeds) in randomised sequence over three consecutive days. Primary outcomes were number of events (apnoea, bradycardia and desaturation) and percentage time SpO(2) < 80% over 24 h. The secondary outcome was percentage time SpO(2) >= 88%. Treatment effects were estimated using linear mixed-effects models. Results Propped/prone positioning significantly reduced events and improved percentage time SpO(2) < 80% and >= 88% compared to both other conditions (all P < 0.001). Outcomes for the feed-rate intervention were not significantly different to control. Conclusions Alternative infant positioning should be considered in preterm infants managed in the neonatal unit.
