High-Flow Nasal Cannula Versus Nasal CPAP as Primary Support in Preterm Respiratory Distress Syndrome
3 juli 2026 uppdaterad av: Kayseri City Hospital
Heated Humidified High-Flow Nasal Cannula Versus Nasal Continuous Positive Airway Pressure as Primary Respiratory Support in Preterm Infants With Respiratory Distress Syndrome: A Randomized Controlled Trial
This single-center randomized controlled trial compared heated humidified high-flow nasal cannula (HHHFNC) with nasal continuous positive airway pressure (nCPAP) as primary noninvasive respiratory support in preterm infants (gestational age 28-34 weeks; birth weight 1000-2000 g) with moderate respiratory distress syndrome.
The primary outcome was treatment failure requiring invasive mechanical ventilation within the first 7 days.

Avslutad
Detaljerad beskrivning
Eighty-six infants were randomized 1:1 to HHHFNC (n=43) or nCPAP (n=43).
Both arms followed identical surfactant, escalation, and weaning protocols.
Outcomes included treatment failure, nasal trauma, sepsis, feeding intolerance, and time to full enteral feeding.
