abstract

  • OBJECTIVES: To identify characteristics and outcomes of infants who received multiple doses of surfactant vs those who received one dose or none. STUDY DESIGN: In this retrospective study, we included neonates of 22-28 weeks' gestation admitted to NICUs in the Canadian Neonatal Network. Patients were divided into three groups: no surfactant, single dose, and multiple doses. The primary outcome was a composite of mortality or any of the major morbidities, including severe neurological injury, bronchopulmonary dysplasia, or ≥stage 3 retinopathy of prematurity. RESULTS: Of 8024 eligible neonates, 2461 (31%) did not receive surfactant, 3545 (44%) received one dose, and 2018 (25%) received >1 dose. Receiving one or more doses of surfactant was associated with significantly higher adjusted odds of mortality or major morbidities in a dose-dependent manner. CONCLUSIONS: Receiving one or more doses of surfactant was associated with adverse neonatal outcomes. Receipt of more than one dose may reflect underlying severe lung immaturity.
