Objective: To evaluate in a randomized, double-blind, placebo-controlled trial the effect of early caffeine on the age of first successful extubation in preterm infants. Study design: Preterm infants born at 23-30 weeks of gestation requiring mechanical ventilation in the first 5 postnatal days were randomized to receive a 20 mg/kg loading dose followed by 5 mg/kg/day of caffeine or placebo until considered ready for extubation. The placebo group received a blinded loading dose of caffeine before extubation. Results: Infants were randomized to receive caffeine (n = 41) or placebo (n = 42). Age at first successful extubation did not differ between early caffeine (median, 24 days; IQR, 10-41 days) and control groups (median, 20 days; IQR, 9-43 days; P =.7). An interim analysis at 75% enrollment showed a trend toward higher mortality in 1 of the groups and the data safety and monitoring board recommended stopping the trial. Unblinded analysis revealed mortality did not differ significantly between the early caffeine (9 [22%]) and control groups (5 [12%]; P =.22). Conclusions: Early initiation of caffeine in this group of premature infants did not reduce the age of first successful extubation. A nonsignificant trend toward higher mortality in the early caffeine group led to a cautious decision to stop the trial. These findings suggest caution with early use of caffeine in mechanically ventilated preterm infants until more efficacy and safety data become available.
