Novel Surfactant Administration Techniques: Will They Change Outcome?

Abstract

Traditionally, surfactant has been administered to preterm infants with respiratory distress syndrome via an endotracheal tube and in conjunction with mechanical ventilation. However, negative consequences of mechanical ventilation such as pneumothorax and bronchopulmonary dysplasia are well known. In order to provide the benefits of surfactant administration without the negative effects of mechanical ventilation, several methods of less invasive surfactant administration have been developed. These methods include InSurE (intubate, surfactant, extubate), pharyngeal administration, laryngeal mask administration, aerosolized surfactant administration, and thin catheter administration (TCA). Of these, TCA has been studied most extensively and holds the most promise as a less invasive and effective mode of surfactant administration to preterm infants. Further studies will aid in determining which patients would benefit most from less invasive surfactant administration.
