Premature Newborns Treated With Less Invasive Surfactant Administration Under Heated Humidified High-flow

Nasal Continuous Airway Pressure (CPAP) or Heated humidified high-flow Air support with nasal cannula (HHHFNC) are among the most commonly used non-invasive respiratory support methods. The purpose of this prospective study was to compare vital findings, blood gas parameters, perfusion index (PI) and plethysmographic variability index (PVI) values in premature infants treated with less invasive surfactant administration (LISA) under HHHFNC or CPAP.

The purpose of this prospective study was to compare vital findings, blood gas parameters, perfusion index (PI) and plethysmographic variability index (PVI) values in premature infants treated with less invasive surfactant administration (LISA) under HHHFNC or CPAP. This study was carried out in Hacettepe University Hospital NICU between January and December 2017. Premature newborns who were on noninvazive respiratory support and were diagnosed as RDS within first 72 hours of life, were taken into the study. Noninvasive respiratory support was provided with nasal CPAP or HHHNFC. Pulse oxymetry measurements were obtained before and 5th, 30th, 60th, 120th , 360th minutes, blood gas analysis was performed immediately before and 120th, 360th minutes after surfactant administration. Post-hoc, one-way difference between two independent means (two groups) statistical analysis was used. Significance P \< 0.05; effect size 0.9; power (1-ß err prob) was found to be 82%.
