A trial comparing continuous positive airway pressure (CPAP) devices in preterm infants

OBJECTIVE: To test the hypothesis that infants born <30 weeks’ gestation supported by Seattle-PAP will have lower rates of continuous positive airway pressure (CPAP) failure than infants supported with conventional, Fisher&Paykel-CPAP (FP-CPAP). STUDY DESIGN: Randomized trial (3/2017-01/2019) at 5 NICUs. The primary outcome was CPAP failure; subgroup analyses (gestational age, receipt antenatal corticosteroids) were performed. RESULTS: A total of 232 infants were randomized. Infants in the Seattle-PAP and FP-CPAP groups had mean gestational ages of 27.0 and 27.2 weeks, respectively. We observed no differences in rates of treatment failure between Seattle-PAP (40/112, 35.7%) and FP-CPAP (38/120, 31.7%; risk difference, 4.1%; 95% CI, −8.1–16.2; P = 0.51). Subgroup analysis indicated no differences in rates of CPAP failure. We observed no differences between the two groups in frequencies of adverse events or duration of respiratory support. CONCLUSIONS: Among infants born <30 weeks’ gestation, rates of CPAP failure did not differ between Seattle-PAP and FP-CPAP.
