To assess whether there is any advantage in the use of corticosteroid to prevent postextubation stridor in children, we conducted a prospective, randomized, double-blind trial of dexamethasone versus saline solution. The patients were evaluated and then randomly selected to receive either dexamethasone or saline solution according to a stratification based on risk factors for postextubation stridor: age, duration of intubation, upper airway trauma, circulatory compromise, and tracheitis. Dexamethasone, 0.5 mg/kg, was given every 6 hours for a total of six doses beginning 6 to 12 hours before and continuing after endotracheal extubation in a pediatric intensive care setting. There was no statistical difference in incidence of postextubation stridor in the two groups; 23 of 77 children in the placebo group and 16 of 76 in the dexamethasone group had stridor requiring therapy (p = 0.21). We conclude that the routine use of corticosteroids for the prevention of postextubation stridor during uncomplicated pediatric intensive care airway management is unwarranted.
