Duration of Surfactant Administration and Impact on Stabilisation of Vital Parameters in Very Preterm Neonates: 1 Minutes Versus 5 Minutes
Sponsor: Medical University of Graz
Summary
Respiratory distress syndrome (RDS) is common in very preterm infants due to surfactant deficiency. Surfactant replacement therapy is lifesaving, and current guidelines recommend the less invasive surfactant administration (LISA) technique. However, the optimal duration of surfactant instillation during LISA has never been systematically evaluated. Rapid instillation may provoke transient hypoxia and bradycardia, while slower administration might improve physiological stability and cerebral oxygenation. This randomised controlled trial investigates whether the duration of surfactant administration (1 minute versus 5 minutes) affects cerebral and systemic oxygen stability in extremely preterm neonates (\< 28 weeks).

Poractant alfa (Curosurf®) - 1-minute administration
Poractant alfa (Curosurf®, Chiesi Pharmaceuticals) administered intratracheally via the Less Invasive Surfactant Administration (LISA) technique over 1 minute. The surfactant is instilled manually through a thin catheter under direct laryngoscopy while the infant remains on continuous positive airway pressure (CPAP) and spontaneous breathing. Pre-specified criteria for aborting the LISA procedure are prolonged bradycardia (HR \< 80 bpm) and/or arterial hypoxia (SpO2 \< 80%) over 60 seconds during surfactant administration starting after the instillation of the LISA catheter. Data of included participants with discontinuation will be collected and analysed.
