Each brand of surfactant has different dosing. Infasurf is 3ml/kg, Curosurf 2.5, and Survanta is 4mil. There may be higher incidence of pulmonary hemorrhage with certain brands of surfactant (Curosurf), but overall RDS causes pulmonary hemorrhage, not surfactant. Therefore prophylactic treatment is ideal before RDS symptoms, rears its ugly head. Treating with surfactant on premature lungs, sooner than later is ideal. The transport nurse needs to know that.
