LISA vs Endotracheal Surfactant in Preterm Neonates: A Lung Ultrasound Distribution Study
A Prospective Pilot Controlled Trial Comparing the Intrapulmonary Distribution of Exogenous Surfactant Between (LISA) and Conventional Endotracheal Intubation in Preterm Neonates With RDS Using Lung Ultrasound and the NOVEL Surfactant Distribution Homogeneity Index (SDHI)

Conditions
Summary
This prospective, non-randomized, unblinded pilot study evaluates and compares the intrapulmonary distribution of exogenous surfactant in preterm neonates when administered via Less Invasive Surfactant Administration (LISA) versus conventional endotracheal intubation (ETT). Lung ultrasound (LUS) will be utilized to assess the pioneer Surfactant Distribution Homogeneity Index (SDHI) to quantify the evenness and extent of surfactant-induced lung aeration. Secondary objectives include evaluating changes in LUS scores, short-term clinical respiratory outcomes, and feasibility parameters for guiding future larger-scale trials.

Interventions
Administration of exogenous surfactant (Beractant, 100 mg/kg in 4 mL/kg) via an endotracheal tube following intubation, accompanied by brief mechanical ventilation and extubation if feasible.
Administration of exogenous surfactant (Beractant, 100 mg/kg in 4 mL/kg) via a thin catheter while the infant is maintained on non-invasive respiratory support (CPAP or NIPPV).
