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.

Primary Outcome Measures:
  • Efficacy - incidence of treatment failure [ Time Frame: Day 1-14 ] [ Designated as safety issue: No ]
  • Need for inhaled nitric oxide or Extracorporeal membrane oxygenation [ Time Frame: Day 1-14 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Changes in oxygenation index [ Time Frame: 6 & 12 hours ] [ Designated as safety issue: No ]
  • Changes in differential saturation [ Time Frame: 6 & 12 hours ] [ Designated as safety issue: No ]
  • Duration of mechanical ventilation [ Time Frame: Days 1-14 ] [ Designated as safety issue: No ]
  • Time from initiation of sildenafil to inhaled nitric oxide or extracorporeal membrane oxygenation [ Time Frame: Days 1-14 ] [ Designated as safety issue: No ]
