BackgroundThe efficacy and safety of early high-frequency oscillatory ventilation as compared with conventional synchronized intermittent mandatory ventilation for the treatment of infants with very low birth weight have not been established.MethodsWe conducted a randomized, multicenter clinical trial to determine whether infants treated with early high-frequency oscillatory ventilation were more likely than infants treated with synchronized intermittent mandatory ventilation to be alive without requiring supplemental oxygen at 36 weeks of postmenstrual age. Eligible infants weighed 601 to 1200 g at birth, were less than four hours of age, had received one dose of surfactant, and required ventilation with a mean airway pressure of at least 6 cm of water and a fraction of inspired oxygen of at least 0.25. Infants were stratified according to birth weight and exposure to prenatal corticosteroids and then randomly assigned to high-frequency oscillatory ventilation or synchronized intermittent mandatory ventilation. Ventilation was managed according to protocols designed to optimize lung inflation and blood gas values.ResultsFive hundred infants were enrolled in the study. Infants randomly assigned to high-frequency oscillatory ventilation were successfully extubated earlier than infants assigned to synchronized intermittent mandatory ventilation (P<0.001). Of infants assigned to high-frequency oscillatory ventilation, 56 percent were alive without a need for supplemental oxygen at 36 weeks of postmenstrual age, as compared with 47 percent of those receiving synchronized intermittent mandatory ventilation (P=0.046). There was no difference between the groups in the risk of intracranial hemorrhage, cystic periventricular leukomalacia, or other complications.ConclusionsThere was a small but significant benefit of high-frequency oscillatory ventilation in terms of the pulmonary outcome for very-low-birth-weight infants without an increase in the occurrence of other complications of premature birth.Copyright 2002 Massachusetts Medical Society
