Clinical Trial Summary

The aim of the present work is to study the cardio-respiratory effects of non-invasive ventilation (nasal high-frequency ventilation and nasal CPAP) as an initial therapy of respiratory distress in moderate and late preterm infants as regard: I. Primary outcomes: - Duration of the non- invasive respiratory support. - Need of invasive ventilation in the first 72 hours. - Short-term complications such as air leak syndromes, pulmonary hemorrhage, intraventricular hemorrhage, and nasal trauma. II. Secondary outcomes: - Need for surfactant administration. - Days on invasive mechanical ventilation. - Days on supplemental oxygen. - Duration of hospital stay. - Mortality rate. III. Hemodynamic changes during the period of non-invasive ventilation.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Superior vena cava blood flow in ml/kg/min	The SVC diameter will be visualized from a high parasternal long axis view. The maximum and minimum internal diameters will be then measured. ? The SVC flow velocity will be visualized from a low subcostal view and the pulsed Doppler recording will be made at the junction of the SVC and the right atrium. ? SVC flow will be calculated using the method described by Kluckow and Evans:(27) SVC flow (ml/kg/min) = [VTI (cm/beat) × 3.14 × (mean SVC diameter2; /4) × heart rate (beat/min)] Body weight in kg 11	first 3 days of life
Primary	Right ventricular output in ml /kg/min	CSA (cm) (Cross sectional area of PV by long axis parasternal RV outflow view - 2D - immediately beneath pulmonary annulus; - mid- systole - inner edge to inner edge) = p x (radius)2 ? VTI (cm) (Velocity Time Integral or Stroke Distance = Distance over which blood travels in once cardiac cycle ? Long axis parasternal RV outflow view). ? SV (ml/beat) (Stroke Volume = CSA x VTI). ? Output (L/min.) COP = SV x HR.	first 3 days of life
Primary	left ventricular output in ml/kg/min	CSA (cm) (Cross sectional area of AV by long axis parasternal view - 2D - immediately beneath aortic annulus - mid- systole - inner edge to inner edge) = p x (radius) 2 . ? VTI (cm) (Velocity Time Integral or Stroke Distance = Distance over which blood travels in once cardiac cycle ? Apical 5- chamber view). ? SV (ml/beat) (Stroke Volume = CSA x VTI). ? Output (L/min.)
