Exogenous surfactant therapy is vital in managing respiratory distress syndrome (RDS) in preterm infants, with less invasive surfactant administration (LISA) gaining popularity. This study aimed to assess the efficacy and short-term outcomes of LISA using beractant and poractant alfa. In a randomized controlled trial, we enrolled preterm infants (28–33+6 weeks) with RDS requiring surfactant. LISA was employed, with beractant at 100 mg/kg or poractant-alfa at 200 mg/kg. Primary outcome was the need for intubation within 72 hours. Among 120 infants, 3.3% in both groups required intubation within 72 hours (p value 1.00, 95% CI 0.14–6.86). No significant differences in secondary outcomes were noted. However, beractant was significantly more economical than poractant-alfa, with a significantly lower surfactant cost and total care cost for infant hospital stays. Beractant and poractant-alfa exhibit similar efficacy in LISA for preterm infants with RDS. Economic considerations, especially in LMICs, favour beractant. (CTRI/2023/03/050375).
