Continuous positive airway pressure (CPAP) is currently used in neonates after mechanical ventilation though it may occasionally be associated with air leaks syndromes or it may fail to support the baby. The pressure difference offered by bilevel continuous positive distending pressure (BiPAP) respect to CPAP may be an advantage to the spontaneously breathing patient. In this study, we compared the efficacy of CPAP and BiPAP in the firstweek post-extubation in a series of very preterm infants. Inborn neonates less than 30 weeks of gestational age who were intubated shortly after birth from January 2011 to December 2017 were enrolled in a retrospective study. The attending clinician assessed the patients for non-invasive respiratory support readiness and allocated them to CPAP (PEEP 4–6 cmH 2 O) or BiPAP (PEEP 4–5 cmH 2 O, rate 10–40; Thigh 0.7–1.2; upper-pressure level 8–10 cmH 2 O). Both techniques were compared for preventing extubation failure within 7 days from extubation as defined per local protocol (primary outcome). Secondary outcomes were: definitive failure of extubation, pneumothorax during non-invasive respiratory support, periventricular leukomalacia, bronchopulmonary dysplasia, sepsis, patent ductus arteriosus and retinopathy of prematurity at discharge. We enrolled 134 neonates; the CPAP group included 89 babies while 45 received BiPAP. Patients did not differ for their general characteristics (EG, antenatal steroids, incidence of SGA, maternal hypertension, surfactant replacement therapy). Short term extubation failure was significantly higher in the former group (23/89 in CPAP vs 5/45 in BiPAP;  p  = .005). No infant developed air leak syndrome. Secondary outcomes were comparable between groups. Multivariate analysis showed that on the whole population the extubation failure was correlated to the insurgence of late-onset sepsis. BiPAP safely reduced early extubation failure compared to CPAP in our cohort of very preterm neonates within 7 days from extubation.

Reducing post-extubation failure rates in very preterm infants: is BiPAP better than CPAP?
