<b><i>Objective:</i></b> To determine whether nasal high-frequency oscillatory ventilation (NHFOV) as a primary mode of respiratory support as compared with nasal continuous airway pressure (NCPAP) will reduce the need for invasive mechanical ventilation in preterm infants (26<sup>0/7</sup>–33<sup>6/7</sup> weeks of gestational age [GA]) with respiratory distress syndrome (RDS). <b><i>Methods:</i></b> This multicenter randomized controlled trial was conducted in 18 tertiary neonatal intensive care units in China. A total of 302 preterm infants born at a GA of 26<sup>0/7</sup>–33<sup>6/7</sup> weeks with a diagnosis of RDS were randomly assigned to either the NCPAP (<i>n</i> = 150) or the NHFOV (<i>n</i> = 152) group. The primary outcome was the need for invasive mechanical ventilation during the first 7 days after birth. <b><i>Results:</i></b> Treatment failure occurred in 15 of 152 infants (9.9%) in the ­NHFOV group and in 26 of 150 infants (17.3%) in the NCPAP group (95% CI of risk difference: −15.2 to 0.4, <i>p =</i> 0.06). In the subgroup analysis, NHFOV resulted in a significantly lower rate of treatment failure than did NCPAP in the strata of 26<sup>+0/7</sup>–29<sup>+6/7</sup>weeks of GA (11.9 vs. 32.4%, 95% CI of risk difference: −39.3 to −1.7, <i>p =</i> 0.03) and birth weight &#x3c;1,500 g (10.4 vs. 29.6%, 95% CI of risk difference: −33.8 to −4.6, <i>p =</i> 0.01). The rate of thick secretions causing an airway obstruction was higher in the NHFOV group than in the NCPAP group (13.8 vs. 5.3%, 95% CI of risk difference: 1.9–15.1, <i>p =</i> 0.01). No significant differences in other secondary outcomes were found between the NHFOV and NCPAP groups. <b><i>Conclusions:</i></b> NHFOV was not superior to NCPAP with regard to the primary outcome when applied as the primary respiratory support for RDS in infants between 26<sup>+0/7</sup> and 33<sup>+6/7</sup> weeks of GA. In the subgroup analysis, NHFOV seemed to improve effectiveness than NCPAP in preterm infants &#x3c;30 weeks of GA.

Objective To investigate the effectiveness and safety of non-invasive high-frequency oscillatory ventilation (NHFOV) in post-extubation preterm infants. Methods This was a randomized, controlled trial. A total of 149 preterm infants aged between 25 to 34 weeks’ gestational age with a birth weight of <1500 g who required invasive mechanical ventilation on admission were included. After extubation, they were randomized to the NHFOV group (n = 47), nasal intermittent positive pressure ventilation (NIPPV) group (n = 51), or nasal continuous positive airway pressure (NCPAP) group (n = 51). We compared the effectiveness and safety among these three groups. Results A total of 139 preterm infants finally completed the study. The reintubation rate was significantly lower in the NHFOV group than in the other groups. The duration of non-invasive ventilation and the length of hospital stay in the NHFOV and NIPPV groups were significantly shorter than those in the NCPAP group. The incidence of bronchopulmonary dysplasia in the NHFOV and NIPPV groups was significantly lower than that in the NCPAP group. The NHFOV group had significantly less nasal injury than the NCPAP group. Conclusion As post-extubation respiratory support in preterm infants, NHFOV has a lower reintubation rate compared with NCPAP and NIPPV, without increasing the rate of complications.
