Randomized Controlled Trial of Surfactant Administration by Laryngeal Mask Airway (LMA)

In this protocol we will conduct a randomized controlled trial where babies with respiratory distress syndrome (RDS) who have not yet reached criteria for intubation, will be randomized to receive surfactant by LMA or to continue receiving standard therapy of nasal CPAP and supplemental oxygen. All babies will be given surfactant by endotracheal tube if they reach "failure" criteria, which is the standard criterion for surfactant administration (i.e., FiO2= 65% while receiving nasal CPAP).

The objective of this RCT is to determine if surfactant can be successfully administered by LMA, thus perhaps avoiding the need for endotracheal intubation. The hypothesis is that fewer babies in the LMA group would reach failure criteria.

  • Nasal CPAP and requirement for supplemental oxygen [ Time Frame: Birth to discharge ]
  • Time to reach full enteral feedings [ Time Frame: Birth to discharge ]
  • Incidence of laryngeal edema [ Time Frame: 96 hours ]
  • Duration of hospitalization [ Time Frame: Birth to discharge ]

Arms Assigned Interventions
Experimental: 1
Surfactant by LMA
Device: Surfactant administered via Laryngeal Mask Airway (LMA)
Standard volume of Infasurf surfactant (3 mL/kg) will be injected in 2-4 aliquots into the proximal end of the LMA.
Other Names:
  • Infasurf
  • LMA
Standard of care
Other: standard of care (nasal CPAP and supplemental oxygen)
Standard of care will be utilized which may mean surfactant is administered
