Nebulization of drugs in a nasal CPAP system.
Aerosolized drugs have been used in infants for the treatment of respiratory distress syndrome and bronchopulmonary dysplasia (beta-agonists, steroids and surfactant) and bronchiolitis due to respiratory syncytial virus (epinephrine and ribavirin). Controlled clinical trials have, however, produced conflicting results, probably due in part to problems with the transportation of the aerosol from the nebulizer to the bronchioli. We have modified a nasal continuous positive airway pressure (CPAP) system permitting an aerosol to flow through a canal to the nasal prongs and into the airways of the infant. It has been used successfully for the administration of epinephrine, salbutamol, budesonide, acetylcysteine, natural surfactant and ribavirin to sick infants. The modified nasal CPAP system is a simple, safe, cost-efficient and baby-friendly system for respiratory support and drug treatment, which can be used in future trials of aerosolized drugs.
