RESPIRATORY DISTRESS SYNDROME, RESPIRATORY DISTRESS SYNDROME
Respiratory distress syndrome (RDS) is a common issue in preterm infants.Preterm infants benefit from early initiation of enteral feedingNoninvasive respiratory support could affect feeding intolerance through several mechanisms. First, part of the pressurized gas flows intended for the respiratory tract is transmitted to the gastrointestinal tract, causing its gaseous distension.The most widely used NRS modalities are nasal continuous positive airway pressure (NCPAP) and heated humidified high-flow nasal cannula (HHHFNC).Based on previous considerations, we hypothesized that HHHFNC may affect feeding intolerance to a lesser extent than NCPAP. We carried out this trial to evaluate the effect of NCPAP vs HHHFNC on high-risk preterm infants (gestational age <30 weeks) with respiratory distress syndrome.
