Inhaled nitric oxide for the postoperative management of pulmonary hypertension in infants and children with congenital heart disease.

Nitric oxide (NO) is a prevalent molecule in the human body responsible for many physiologic activities including pulmonary vasodilation. An exogenous, inhaled form (iNO) exists that mimics this action without directly affecting systemic blood pressure. This therapy has been implemented in the treatment of pulmonary hypertension. This review examines the efficacy of iNO in the postoperative management of infants and children with congenital heart disease.
