Comparison between two natural surfactant poractant alfa and bovine lipid extract in respiratory distress syndrome amongst preterm neonates-a quasi-experimental study

Srikanta Baske, Sudip Saha, Partha Pratim Pal


Background: A comparison study of two natural surfactants in preterm babies admitted in neonatal intensive care unit (NICU) and sick newborn care unit (SNCU) of a tertiary care hospital to find out efficacy and consequences.

Methods: A Quasi-experimental study. InSurE technique applied for administering Poractant alfa (CUROSURF) and bovine surfactant (NEOSURF) in two comparison group of preterm neonates with respiratory distress syndrome (RDS) during May 2018 to April 2019. The need of mechanical ventilation, oxygen requirement (FiO2), duration of oxygen requirement and the consequences were assessed.

Results: The CUROSURF is 6.67% more efficacious than NEOSURF in respect to less requirement of mechanical ventilation. The differences were found between two groups in terms of FiO2adjusted (33.49% vs 37.17%) and common side effects respectively but the difference of mean duration of oxygenation (69.8 hrs vs 111.9 hrs) was less and statistically significant in CUROSURF group. Mean duration of hospitalization (9.55 day’s vs 14.9 days) also were found to be less and statistically significant.

Conclusions: Treatment with CUROSURF was associated with faster improving oxygenation, less additional doses, and decreased need of mechanical ventilation.
