PPHN: is sildenafil the new nitric? A review of the literature.
Persistent pulmonary hypertension of the newborn (PPHN) is a life-threatening neonatal pathology resulting from poor hemodynamic and respiratory transition to extrauterine life. Inhaled nitric oxide (iNO) is a current, commonly used treatment of PPHN. However, some infants with PPHN do not respond to iNO therapy. Because of the significant morbidity and mortality associated with PPHN, it is useful to look at other possible therapies. This article explores the use of sildenafil in the treatment of PPHN, either as a supplement to iNO or as an alternative to iNO. Current research, including a case study, is reviewed. An emphasis is placed on the administration and efficacy of sildenafil in synergy with, and in lieu of, current iNO therapy in the treatment of PPHN.
