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.

Study Design


Intervention

Device:
NHFOV
The neonate patients with respiratory distress will have nasal high frequency ventilation as an initial mode of respiratory support.
NCPAP
The neonate patients with respiratory distress will have nasal continuous positive airway pressure as an initial mode of respiratory support.

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

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.

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.)
