Trial Outcomes & Findings for NHFOV as Primary Support in Very Preterm Infants With RDS (NCT NCT05141435)

NCT ID: NCT05141435

Last Updated: 2025-07-24

Results Overview

The respiratory support failure will be considered if one of the following occurs: (1) severe respiratory acidosis (defined as PaCO2 \>60mm Hg with pH\<7.2) for at least 1hour; (2) hypoxia refractory to study intervention (defined as SpO2 \<90%, with FiO2=0.4 and maximal pressures allowed in the study arm) for at least 1 hour after the administration of surfactant; (3) severe apnoea (defined as recurrent apnoea with \>3 episodes/hour associated with heart rate \<100/min or a single episode of apnoea requiring bag and mask ventilation) and (4) attending physician determined that urgent intubation is necessary.

Participant Flow

From August, 2022, through August, 2024, a total of 20 centers screened 729 infants, of which 405 were eligible. We recruited 360 infants (180 in each group), to account for dropouts. Finally, 342 infants completed the trial (170 in NHFOV; 172 in NCPAP group.)

Measure
NCPAP
infants receive primary non-invasive respiratory support by mean of nCPAP: neonates assigned to the nCPAP group will be started on a pressure of 6 cmH2O( adjust range:6-10 cmH2O) , with FiO2 (0.21-0.40)adjusted to target SpO2 from 89% to 94%. CPAP will be provided by either variable flow or continuous flow devices, as there is no clear evidence that one type of CPAP generator would be better than any other by pure CPAP system. infants receive primary non-invasive respiratory support by mean of NHFOV: neonates assigned to NHFOV will be started with the following boundaries: a) Paw of 6 cmH2O (the range 6-10 cmH2O); b) frequency of 10 Hz (the range 8-12 Hz). c) Inspiratory time 50% (1:1). d) amplitude 15 cmH2O(the range 15-25 cmH2O) NHFOV will only be provided with piston/ membrane oscillators able to provide an active expiratory phase (that is, Acutronic FABIAN-III, SLE 5000, Loweinstein Med LEONI+, Sensormedics 3100A).

CPAP will be provided by either variable flow or continuous flow devices, as there is no clear evidence that one type of CPAP generator would be better than any other by pure CPAP system. infants receive primary non-invasive respiratory support by mean of NHFOV: neonates assigned to NHFOV will be started with the following boundaries: a) Paw of 6 cmH2O (the range 6-10 cmH2O); b) frequency of 10 Hz (the range 8-12 Hz). c) Inspiratory time 50% (1:1). d) amplitude 15 cmH2O(the range 15-25 cmH2O) NHFOV will only be provided with piston/ membrane oscillators able to provide an active expiratory phase (that is, Acutronic FABIAN-III, SLE 5000, Loweinstein Med LEONI+, Sensormedics 3100A).
