nCPAP-NAVA-Backup Versus Standard nCPAP for Severe Apnea in Preterm Infants ≤28 Weeks (NAVAPNEA)
Effect of nCPAP-NAVA-backup Mode Versus Standard nCPAP Mode on the Reduction of Severe Apnea in Preterm Infants ≤ 28 Weeks - a Crossover Trial
The goal of this clinical trial is to determine whether nasal continuous positive airway pressure (nCPAP) with neurally adjusted ventilatory assist (NAVA) backup ventilation (nCPAP-NAVA-backup mode) reduces the rate of severe apnea in extremely preterm infants ≤28 weeks' gestation compared with standard nasal continuous positive airway pressure (nCPAP mode). Severe apnea episodes is defined as breathing pause with oxygen levels ( SpO2) below 85% lasting at least 5 seconds and/or heart rate (HR) below 100 beats/minute lasting at least 5 seconds.
Each participant will receive both interventions in a randomized order, serving as their own control. The total duration of the intervention will be 24h. Each intervention period will last 12 hours. A washout period of 3 hours will be included between intervention periods to minimize potential carryover effects.
Randomized sequences to avoid order effects:
- Sequence A: nCPAP mode → nCPAP-NAVA-backup mode
- Sequence B: nCPAP-NAVA-backup mode →nCPAP mode

Expérimental: Sequence A: nCPAP then nCPAP-NAVA-Backup
Preterm infants randomized to receive 12 hours of standard nCPAP mode followed by 12 hours of nCPAP-NAVA-backup mode (total 24 hours) on a Servo-n ventilator. A 3-hour washout period at the start of each period is excluded from analysis. |
Standard nasal CPAP delivered via a Servo-n ventilator, with continuous monitoring of the electrical activity of the diaphragm (Edi) through an Edi catheter that also serves as the feeding tube. When an apnea exceeds the preset apnea time, pressure-controlled backup ventilation is triggered automatically. Backup and PEEP settings follow unit standards, and PEEP is kept constant throughout the study. Duration: 12 hours. Standard nasal CPAP delivered via nasal prongs or mask on the same Servo-n ventilator and circuit, with PEEP and FiO₂ managed according to standard clinical practice. Duration: 12 hours. |
