LISA Eligibility and LISA Success in Extremely Preterm Infants: A Single-Center Experience.
Neonatology 2024 April 11
INTRODUCTION: Less invasive surfactant application (LISA) is associated with improved short-term outcomes in preterm infants. Data on LISA eligibility and success for infants <28 weeks of gestation are lacking.
METHODS: Preterm infants <28 weeks of gestation who were born and actively treated in our tertiary care center in 2018 were included in the retrospective study. We assessed baseline characteristics, delivery room (DR) management, LISA success and complications, and short-term outcome.
RESULTS: In total, 57 infants received LISA in the DR. LISA eligibility was 73% at 22 weeks, 88% at 23 weeks, and >90% at gestational ages >24 weeks. LISA was successful in 63% of infants. LISA failure was associated with increased risk for high-grade IVH (OR 17.88), death (OR 10.94), and a reduced chance for survival without complications (OR 8.75).
CONCLUSION: Our report justifies LISA as a mode for surfactant application in preterm infants. It contributes to the call for studies to define risk factors for LISA failure.
