Randomized Controlled Trial Clinical TrialEffectiveness of dexamethasone in preventing extubation failure in preterm infants at increased risk for airway edema.
We studied 50 preterm infants who had multiple or traumatic endotracheal intubations, or whose duration of endotracheal intubation was > or = to 14 days, and who were considered at high risk for airway edema. These infants were enrolled in a prospective, randomized, controlled clinical trial to assess whether prophylactic dexamethasone therapy would be effective in the prevention of postextubation stridor and respiratory distress. At study entry, both groups had similar weights, postnatal ages, methylxanthine use, ventilator settings, blood gas values, and pulmonary function test results (dynamic compliance, total respiratory resistance, tidal volume, peak-to-peak transpulmonary pressure, minute ventilation, and peak inspiratory and expiratory flow rates). ⋯ Of 23 control infants, 10 had postextubation stridor compared with 2 of 27 dexamethasone-treated patients (p < 0.006). Of the 23 control patients, 4 required reintubation compared with none of the treated group (p < 0.05). We conclude that the prophylactic use of corticosteroids for the prevention of postextubation stridor and respiratory distress is efficacious in low birth weight, high-risk preterm infants.
