BACKGROUND: Standard-dose caffeine improves white matter microstructural development assessed by diffusion magnetic resonance imaging (MRI). We hypothesized that early high-dose caffeine would result in further improvement in white matter microstructural development.
METHODS: Seventy-four preterm infants (<= 30wk gestational age) we're randomly assigned to either a high (80 mg/kg i.v.) or standard (20 mg/kg i.v.) loading dose of caffeine citrate in the first 24h of life. MRI and neurobehavioral testing were undertaken at term equivalent age. Infants returned at 2 y of age for developmental testing.
RESULTS: Clinical characteristics were similar between groups, with the exception of higher maternal age in the high-dose caffeine group. There was an increased incidence of cerebellar hemorrhage in infants randomized to high-dose caffeine (36 vs. 10%, P = 0.03). Infants in the high-dose caffeine group also demonstrated more hypertonicity (P = 0.02) and more deviant neurologic signs (P = 0.04) at term equivalent age. Diffusion measures at term equivalent age and developmental outcomes at 2 y of age did not differ between groups.
CONCLUSION: Preterm infants randomized to early high-dose caffeine had a higher incidence of cerebellar injury with subsequent alterations in early motor performance. The results of this pilot trial discourage a larger randomized controlled trial.
