Comparison of porcine versus bovine surfactant in preterm respiratory distress syndrome: Evidence from real-world data. A multicentre collaboration from Karnataka.

Background & Objectives: Porcine surfactant (200 mg/kg initial dose) seems to be superior to bovine surfactants (100 mg/kg) in respiratory distress syndrome (RDS). There is limited data on the choice of surfactant from the developing world. Logically, using higher doses of porcine surfactant comes with an additional cost burden.
