Sildenafil as “first line therapy” in pulmonary persistent hypertension of the newborn?

Abstract

Despite the recent advances, the clinical approach to persistent pulmonary hypertension of the newborn (PPHN) still represents an important challenge for neonatologists. The care of newborns with PPHN requires meticulous therapeutic and ventilation strategies including, besides the stabilization of the newborn, the use of nitric oxide and high-frequency ventilation. However, not all the neonates with PPHH are responsive to this clinical approach. Recent studies have proposed the use of sildenafil, a phosphodiesterase 5 inhibitor, in refractory forms of PPHN. The aim of this study is to review the cases and the clinical approach of PPHN in the Neonatal Intensive Care Unit of Meyer Children Hospital in the year 2009 and to discuss the possible role of sildenafil in the management of PPHN.
