Due to the small size of the study, there will not be an interim analysis. Hypoxia and respiratory distress can be associated with poor outcome. Any patients developing significant respiratory distress, as outlined by above reintubation and NCPAP recommendations, will be taken off NC or oxygen hood and be placed back on assigned arm of treatment when attending physician determines infant is clinically able. Given the small study size and low expectations of severe adverse events, we do not plan a scheduled formal DSMB process. Infants in the study will be monitored for serious adverse events that are study related (e.g. respiratory distress necessitating escalation of care). If more than 6 such events occur during the course of the study, an independent ad hoc DSMB (including at least one neonatologist and one biostatistician) will be convened to make a judgment regarding continuation of the trial.
