This study – led by Alain Cuna, from the University of Missouri-Kansas City, looked at what happened to babies with lung problems whose breathing tubes were unable to be removed (failed to extubate) even after a course of systemic corticosteroids. 74 babies took part in the study, of whom 41 were successfully extubated. Those babies whose breathing tubes could not be removed after their treatment with corticosteroids were more likely to die or suffer longer-lasting lung problems. They were also more likely to need a tracheostomy and gastrostomy as well as needing to spend a longer time in hospital and have mechanical ventilation.
