Evaluation of methods of surfactant administration in the delivery suite?

Abstract

Surfactant administered in the delivery suite might prevent or reduce the severity of subsequent respiratory distress syndrome. This review describes the evidence for surfactant delivery methods with relationship to their relevance in the delivery suite. The techniques include delivery using a thin catheter with the first breath, by the intubation-surfactant extubation procedure, less invasive surfactant administration (LISA) technique, using a laryngeal mask airway (LMA), or by nebulisation. There have been few randomised trials that have evaluated outcomes using these techniques in the delivery suite, and these were early trials. Currently, practitioners favour use of nasal continuous positive airway pressure with early rescue surfactant. Whether prophylactic surfactant given by the LISA technique or other techniques, such as via a LMA in the delivery suite, is more beneficial merits testing. This will require appropriately designed randomised trials with long-term outcomes.
