Resumen breve

The purpose of this multicenter trial is to determine if indomethacin prevents bleeding in the brain of very low birth weight preterm infants.

Descripción detallada

Intraventricular hemorrhage (IVH) or bleeding in the brain remains a major problem of preterm infants. This randomized, placebo-controlled multicenter trial enrolled 505 infants of 600 to 1250g birth weight to determine if indomethacin lowers the incidence of IVH, and 125 term infant controls. During this longitudinal trial, follow-up assessments have been performed at the ages of 3, 4 1/2, 6, 8, 12 and 16 years. The initial results at age 3 years revealed no advantages to the indomethacin group over and above the decreases in IVH, however, the results did show a significant increase in ventriculomegaly in the "placebo" group. Results at 4 1/2, 6 and 8 years of age showed beneficial effects of indomethacin on cognitive and behavioral outcomes over and above the effects on preventing IVH but not at later ages. At 12 and 16 years, no significant influence of indomethacin on cognitive outcome was noted.

Age, gender and zip-code matched control subjects were added when the preterm subjects were 8 years. Throughout all subsequent testing, term controls have higher IQ and Peabody Picture Vocabulary Scores.

Additional longitudinal volumetric, functional and diffusion tensor MR imaging studies showed differences between preterm and term control subjects at 8, 12 and 16 years of age. These were consistent with utilization of the right hemisphere and left cerebellum for language in the preterm group compared to term controls. No effects of indomethacin were seen.

The study closed on 31 March 2012.
