Abstract
|
|
|
Purpose: Persistent pulmonary hypertension of the newborn (PPHN) is a potentially fatal disease. Inhaled iloprost, a stable analogue of prostacyclin, has recently been used as a therapeutic option. However, there are no clinical guidelines on the use of iloprost, specifically for neonates. This study aimed to suggest the use of inhaled iloprost as a rescue therapy for PPHN based on our experience.
Methods: The efficacy and adverse events of inhaled iloprost were evaluated prospectively in nine full-term neonates with PPHN. We monitored the following parameters: fraction of inspired oxygen (FiO2), respiratory severity score (RSS), heart rate, and mean blood pressure.
Results: The inhalation dose was 1 to 2 μg/kg initially, and 4 to 8 inhalations per day were applied over 2 to 8 days, except in the case of one neonate who died 2 days after birth. Echocardiographic findings, changes in FiO2, and RSS improved within the next 7 days in eight of the nine patients. Severe side effects on heart rate and blood pressure were not observed.
Conclusion: Our experience suggests that inhaled iloprost can be used as a first-line treatment in newborn infants with PPHN when inhaled nitric oxide is not available. To the best of our knowledge, this report is the first prospective case series on the use of inhaled iloprost in PPHN.
