Persistent pulmonary hypertension of the newborn (PPHN) is an essential cause for hypoxic respiratory failure with significant morbidity and mortality in term and near-term neonates. Hydrocortisone has been shown to decrease oxygen dependency and pulmonary hypertension in neonates with meconium aspiration syndrome and animal studies, respectively. We hypothesize that hydrocortisone will improve oxygenation in term and near-term infants with pulmonary hypertension. We performed a retrospective chart review of all infant with PPHN who received intravenous hydrocortisone therapy as a rescue for severe PPHN. Clinical response was objectively measured using, oxygenation index (OI), PaO2/FiO2 ratio, and inotrope score before, during, and after the hydrocortisone course. We found that hydrocortisone administration resulted in significant improvement of systolic blood pressure, OI, and PaO2/FiO2. In conclusion, hydrocortisone increased systolic blood pressure and improved oxygenation in term and near-term infants with persistent pulmonary hypertension. Prospective randomized trials are required to evaluate these findings further.
