Brief Summary:
To determine the efficacy of iv sildenafil in term and near term infants with PPHN (persistent pulmonary hypertension of the newborn), by measuring the need for inhaled nitric oxide (iNO) or extracorporeal membrane oxygenation (ECMO) compared to a historical control group not treated with sildenafil.

Arm Intervention/treatment
Experimental: Sildenafil
iv sildenafil
Drug: Sildenafil
Loading dose of 0.1 mg/kg for 30 minutes followed by maintenance treatment of 0.03 mg/kg.h for up to 14 days

Primary Outcome Measures :
  1. Efficacy - incidence of treatment failure [ Time Frame: Day 1-14 ]
  2. Need for inhaled nitric oxide or Extracorporeal membrane oxygenation [ Time Frame: Day 1-14 ]

Secondary Outcome Measures :
  1. Changes in oxygenation index [ Time Frame: 6 & 12 hours ]
  2. Changes in differential saturation [ Time Frame: 6 & 12 hours ]
  3. Duration of mechanical ventilation [ Time Frame: Days 1-14 ]
  4. Time from initiation of sildenafil to inhaled nitric oxide or extracorporeal membrane oxygenation [ Time Frame: Days 1-14 ]
