Newborns receiving Survanta\u00ae or Curosurf\u00ae comprised the control group. The main outcome measures were mortality rates at 72 hours and at 28 days of life; the typical complications of prematurity as evaluated on the 28th day of life were defined as secundary outcomes.Results No differences were observed between the Butantan (n=154) and control (n=173) groups in relation to birth weight, gestational age, sex, and prenatal use of corticosteroids, or in mortality rates both at 72 hours (14.19% versus 14.12%; p=0.98) and at 28 days (39.86%versus 33.33%; p=0.24) of life. Higher 1- and 5-minute Apgar scores were observed among control group newborns. No differences were observed as regards the secondary outcomes, except for greater need for supplemental oxygen and a higher incidence of interstitial pulmonary emphysema in the Butantan group.Conclusion The mortality rates at 72 hours and 28 days of life and the incidence of major complications of prematurity were comparable to those found with the animal-derived surfactants commercially available in Brazil, showing the efficacy and safety of the new surfactant in the treatment of respiratory distress syndrome in newborns.<\/jats:p>","DOI":"10.1590\/s1679-45082014ao3095","type":"journal-article","created":{"date-parts":[[2015,1,21]],"date-time":"2015-01-21T22:16:56Z","timestamp":1421878616000},"page":"397-404","source":"Crossref","is-referenced-by-count":12,"title":["A
