High Flow Nasal Cannula in Comparison With Nasal Continuous Positive Airway Pressure in the Management of Respiratory Distress Syndrome

To compare the primary outcome, failure of extubation defined by the need for re-intubation and mechanical ventilation within 5 days of initial extubation and secondary outcomes, morbidities and mortality after using of heated humidity high flow nasal cannula (HHHFNC) and Nasal Continuous Positive Airway Pressure (NCPAP) in the immediate post-extubation period for preterm infants between 24 and 28 weeks gestation with respiratory distress syndrome.
