Multicenter study of surfactant (beractant) use in the treatment of term infants with severe respiratory failure

Objective: The purpose of this study was to determine whether surfactant (beractant) administration to term newborns in respiratory failure and at risk for requiring extracorporeal membrane oxygenation (ECMO) treatment would significantly reduce the incidence of severe complications through 28 days of age and the need for ECMO. Study design: A multicenter (n = 44), randomized, double-blind. placebo-controlled tr;al was conducted. Infants weighing 2000 gm or more with gestational ages of 36 weeks or greater were stratified by diagnosis (meconium aspiration syndrome, sepsis, or idiopathic persistent pulmonary hypertension of the newborn) and oxygenation index (15 to 22, 23 to 30, 31 to 39) and then randomly assigned to receive four doses of beractant, 100 mg/kg (n = 167), or air placebo (n = 161) before ECMO treatment and four additional doses during ECMO, if ECMO was required, The incidence of untoward effects (including hemorrhagic, neurologic, pulmonary renal, cardiovascular, infectious, metabolic, and technical complications) occurring before and after randomization and through 28 days of age or discharge were recorded. Results: The two treatment groups were comparable in baseline parameters, including birth weight, sex, gestational age, oxygenation index, and primary diagnosis. There was no difference in the incidence of severe complications. The need for ECMO therapy was significant lv less in the surfactant group than in the placebo group (p = 0.038); this effect was greatest within the lowest oxygenation index stratum (ii to 22; p = 0.013). Conclusions: Use of surfactant, particularly in the early phase of respiratory failure, significant decreases the need for ECMO in the treatment of term newborns with respiratory failure, without increasing the risk of complications.
