title: Childhood outcome after early high-frequency oscillatory ventilation for neonatal respiratory distress syndrome.
abstract: OBJECTIVE
  In a previous multicenter controlled clinical trial, we randomly assigned surfactant-treated premature newborns with moderate to severe respiratory distress syndrome to early treatment with high-frequency oscillatory ventilation (HFOV) or to conventional ventilation (CV). Compared with control infants who were treated with CV, neonates who were treated with HFOV using a strategy designed to recruit and maintain lung volume and minimize oxygen exposure had clinical evidence of improved pulmonary outcome and less lung injury. We report a follow-up study designed to determine whether clinical differences persisted between these study groups.
  
  
  METHODS
  Patients were recruited from 81 survivors at 1 center (Provo, Utah) and evaluated for sociodemographic and health history, growth, mental development, motor proficiency, and pulmonary function.
  
  
  RESULTS
  Eighty-seven percent of the cohort who originally were assigned to treatment with HFOV (n = 36) or CV (n = 33) were seen in follow-up at a mean age of 77 months (6.4 years). There were no differences in the frequency of hospitalization, pulmonary illness, asthma, or disabilities. Growth, verbal IQ, and motor development were appropriate for age and not different between groups. Patients who initially were randomized to treatment with CV showed pulmonary function evidence of decreased peak expiratory flow, increased residual lung volume, and maldistribution of ventilation.
  
  
  CONCLUSIONS
  Neurodevelopmental childhood outcome after early intervention HFOV was normal and not different compared with patients who were treated with CV. Surfactant replacement combined with early HFOV using a lung recruitment strategy ameliorates the acute lung injury in respiratory distress syndrome that predisposes some preterm infants to develop chronic lung disease.
