Oral Sildenafil in Persistent Pulmonary Hypertension Secondary to Meconium Aspiration Syndrome in Newborns (OSiNPH)
Meconium Aspiration Syndrome, Persistent Pulmonary Hypertension of Newborn
About this trial
This is an interventional treatment trial for Meconium Aspiration Syndrome focused on measuring MAS, PPHN, Sildenafil, Newborn, Pulmonary Hypertension
Eligibility Criteria
Inclusion Criteria:
- Newborns were diagnosed with MAS if any of the two of the following three criteria were present. (1) Meconium staining of liquor or staining of umbilical cord or skin or nails. (2) Respiratory distress, within one hour of birth. (3) Radiological evidence of aspiration pneumonitis (atelectasis and/or hyperinflation). Newborns with MAS diagnosed with clinical PPHN were enrolled in the study for drug trial. PPHN was determined either clinically by loud P2(second component of second heart sound), 10% or greater pre-/post ductal difference in arterial oxygenation (obtained by acid base gas analysis) or upper limb- lower limb SpO2 difference (obtained by pulse oximetry).
Exclusion Criteria:
- (a) babies with congenital heart disease (b) congenital anomalies particularly those which were incompatible to life or which was the cause for respiratory distress e.g. diaphragmatic hernia (c) Respiratory morbidities such as hyaline membrane disease, congenital pneumonia (d) Babies with PPHN secondary to MAS admitted after 12 hours of delivery (e) Non availability of consent of guardian for interventional procedures

Oral Sildenafil
Distilled water
In group A, newborns received oral Sildenafil solution through feeding tube which was prepared by crushing a 50 mg tablet of sildenafil in distilled water to make a concentration of 5 mg/ml. The protocol for dosing was (1) first dose of 1 mg/kg/dose within 30 minutes admission or within 12 hours of delivery (whichever earlier), (2) Dosing every six hours for a maximum of 8 doses.
In group B, newborns received placebo. The protocol for dosing was (1) first dose of 1 mg/kg/dose within 30 minutes admission or within 12 hours of delivery (whichever earlier), (2) Dosing every six hours for a maximum of 8 doses.
