简要总结
The purpose of this study is to to study the role of oral Sildenafil in Persistent Pulmonary Hypertension of Newborn (PPHN) secondary to Meconium Aspiration Syndrome (MAS) in newborns and to study risk factors of MAS developing into PPHN.
详细描述
Design: Randomized control trial Setting: Neonatal intensive care unit in a tertiary care hospital Patients: Patients diagnosed with MAS with PPHN according to clinical criteria. 97 patients with MAS were enrolled in the study over a period of 8 months, out of which 40 patients with PPHN were randomized into two groups.
Intervention: Group A received Sildenafil through a feeding tube (1 mg/kg/dose q6h) for 8 doses. Group B received a placebo. Outcome measures: Improvement in oxygen saturation (SpO2), oxygenation index (OI), duration of hospitalization and mechanical ventilation and mortality.

入选标准
- •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).
排除标准
- •(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
研究组 & 干预措施
Oral Sildenafil
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.
干预措施: Oral Sildenafil (Drug)
Distilled water
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.
干预措施: Placebo (distilled water) (Drug)
