Nitric oxide treatment for pulmonary hypertension after neonatal cardiac operation.
This report describes a newborn with transposition of the great arteries who underwent a Blalock-Taussig shunt with transient improvement in oxygenation, but required emergent insertion of a central shunt later the same day due to progressive hypoxia and cardiac arrest. Two hours after central shunt insertion, sudden episodes of hypoxia and hypotension developed that were resistant to all pharmacologic therapy. Inhaled nitric oxide (25 ppm) was then administered with dramatic improvement in oxygenation and hemodynamics within minutes. The patient's condition stabilized after these measures, and nitric oxide therapy was discontinued after 2 days.
