Laryngeal Mask for Minimally-invasive Surfactant Administration: A Narrative Review

Abstract

The cornerstone of treatment for respiratory distress syndrome in preterm infants is surfactant administration, traditionally performed through an invasive procedure involving tracheal intubation and mechanical ventilation. Consequently, there has been a growing interest in exploring less invasive methods of surfactant delivery to mitigate the associated risks. Currently, several techniques are under evaluation, including intratracheal instillation using a thin catheter, aerosolized or nebulized administration, and guided administration by supraglottic airway devices. One such method is surfactant administration through laryngeal or supraglottic airway, which involves placing a laryngeal mask without the need for laryngoscopy and administering surfactant through the device. The simplicity of laryngeal mask insertion could potentially streamline the surfactant delivery process, eliminating the necessity for advanced skills. This narrative review aimed to assess the current evidence in the literature regarding the benefits and risks associated with surfactant administration through a laryngeal supraglottic airway.
