E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
• To demonstrate (short-term objective) that fluid bolus and dobutamine infusion as compared to fluid bolus and placebo infusion increases the proportion of neonates achieving and maintaining a clinically acceptable haemodynamic status with the dobutamine infusion alone in the first 72 hours from birth. • To demonstrate (medium-term objective) that fluid bolus and dobutamine infusion as compared to fluid bolus and placebo infusion increases the proportion of neonates alive without severe neurological complications at 36±2 weeks PMA. |
• Demostrar (objetivo a corto plazo) que la infusión de bolo fluido y dobutamina en comparación con la infusión de bolo fluido y placebo aumenta la proporción de recién nacidos que logran y mantienen un estado hemodinámico clínicamente aceptable con la infusión de dobutamina sola en las primeras 72 horas desde el nacimiento. • Demostrar (objetivo a medio plazo) que la infusión de bolo fluido y dobutamina en comparación con la infusión de bolo fluido y placebo aumenta la proporción de neonatos vivos sin complicaciones neurológicas graves a las 36 ± 2 semanas de edad Post Menstrual. |
|
E.2.2 | Secondary objectives of the trial |
• Short term (pharmacodynamic) endpoint: proportion of neonates achieving and maintaining a clinically acceptable haemodynamic status with the dobutamine infusion alone in the first 72 hours from birth. • Medium term (clinical) endpoint: Proportion of neonates surviving without severe neurological complications at 36±2 weeks PMA. |
• Punto final a corto plazo (farmacodinámico): proporción de recién nacidos que logran y mantienen un estado hemodinámico clínicamente aceptable con la infusión de dobutamina sola en las primeras 72 horas desde el nacimiento. • Punto final a medio plazo (clínico): proporción de neonatos que sobreviven sin complicaciones neurológicas graves a las 36 ± 2 semanas de Edad Post Menstrual. |
