This CURLISPAP study was a multicenter, randomized controlled study at six level III neonatal intensive care units (NICUs) in Turkey. The protocol was approved by the ethics committee of each participating centre and Turkish Ministry of Health, Turkish Medicines and Medical Devices Agency.~Non invasive ventilated preterm infants with respiratory distress syndrome and gestational age from 241/7 weeks to 296/7 weeks were enrolled within 6 h of birth. Infants with major congenital malformations, need of mechanical ventiation, need of entubation in delivery room and lack of parental consent were excluded. Enrolled infants will randomize into two study groups (NIPPV group and CPAP group). The short binasal prongs will use as interface. For all the groups, if the fraction of inspired oxygen (FiO2) requirement is persistently higher than 0.30 target SpO2 90-94%.~For all groups Surfactant by LISA technique and with special catheter (LISAcath, Chiesi Pharmaceutics) of surfactant (Curosurf, Chiesi Pharmaceutics) 200 mg/kg.~The primary end-point, need of mechanical ventilation within 72 hours following surfactant treatment, will compared between the groups. Short and long-term neonatal outcomes will also evaluate.
Non invasive ventilation is important in the care of preterm infants with respiratory failure, and surfactant treatment can be use with non invasive ventilation. However, there is no consensus on the best non-invasive ventilation mode for surfactant treatment in preterm infants.~Objective: To compare the effectiveness of nasal intermittent positive pressure ventilation (NIPPV) versus nasal continuous positive airway pressure (CPAP) in preterm infants ≤ 29 week gestational age.
