The use of less invasive surfactant administration (LISA) in the United States with review of the literature

Backgroundthe majority of extremely low gestational age neonates undergo intubation for surfactant therapy. less invasive surfactant administration (lisa) uses a thin catheter inserted into the trachea to deliver the surfactant. during the procedure, the infant is breathing spontaneously while supported with continuous positive airway pressure. although lisa is widely adapted in europe and australia, the rate of lisa use in the united states is unknown.study designthe aim of this study is to evaluate the use of lisa in the us. a web-based survey was distributed via surveymonkey to 2550 neonatologists from aap’s sonpm mailing list.resultsof the 472 neonatologists who answered the survey, 15% used lisa either as a part of routine care (8%) or as part of research (7%).conclusionunlike several regions of europe, lisa is not widely used in the us. future studies should address ambiguities regarding infant selection, procedure training and “roadblocks” to its broader application.
