Comparison of Efficacy of Less Invasive Surfactant Treatment Under Nasal CPAP and Nasal IPPV

Comparison of Efficacy of Less Invasive Surfactant Treatment Under Nasal CPAP and Nasal IPPV in Premature Babies: CURLISPAP Study

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.

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.

Ventilator-derived NCPAP will be administered using binasal prongs. Standard Devices or infant flow-driver device. Initial NCPAP settings are: PEEP:6 cmH2O and FiO2: adjusted to keep preductal sPO2 between %90-94. Failure is defined as FiO2 requirement of >%50, capillary blood gas obtained at the 4th hour of therapy showing pH<7.20 or pCO2>60 cmH2O.

Ventilator-derived NIPPV will be administered using binasal prongs. Standard Devices or infant flow-driver device. Initial NIPPV settings are: PEEP:6 cmH2O, PIP: 15 cmH2O, Rate: 30-40/ bpm and FiO2: adjusted to keep preductal sPO2 between %90-94. Failure is defined as FiO2 requirement of >%50, capillary blood gas obtained at the 4th hour of therapy showing pH<7.20 or pCO2>60 cmH2O.
