Natural Versus Synthetic Surfactant Therapy in Respiratory Distress Syndrome of Prematurity.

OBJECTIVES: To compare the clinical efficacy and the cost of treatment between the newborns who received either a natural or a protein-free synthetic surfactant for respiratory distress syndrome (RDS) of prematurity.

METHODS: This is a retrospective analytical study incorporating comparisons of clinical parameters and cost in newborns having RDS of prematurity who received either Survanta (bovine lung extract), a natural surfactant or Surfact (protein-free colfosceril palmitate), a synthetic surfactant.

RESULTS: There were 100 newborns who received either of the natural (n = 52) or synthetic (n = 48) surfactant with mean (SD) gestational age and mean (SD) birth weight of 31.5 (2.6) wk, 1425 (461) g and 32.2 (2.2) wk, 1519 (413) g, respectively. Majority of the newborns (> 90%) received endotracheal surfactant within the first 24 h of life and had similar baseline characteristics in either group. No differences were noted in ventilator settings on admission and 24 h after surfactant/admission. Oxygen requirement, extubation age, complications, hospital stay, and mortality were similar across groups, except that the necrotizing enterocolitis was noted only in natural surfactant group. There was a significant pharmacy cost savings in synthetic surfactant group.

CONCLUSION: Synthetic surfactant was comparable to natural surfactant with regard to outcomes, like ventilator settings, hospital stay, and mortality. Pharmacy cost was less in synthetic surfactant group.
