title: Neurodevelopmental assessment of very low birth weight neonates: effect of germinal matrix and intraventricular hemorrhage.
abstract: During a recent 36-month interval, all neonates of less than or equal to 1250 gram birth weight who were admitted to our Newborn Special Care Unit and survived the first 36 postnatal hours underwent either computed tomography or echoencephalography or both for the assessment of neonatal germinal matrix hemorrhage and intraventricular hemorrhage. Seventy of the 164 long-term surviving infants experienced neonatal germinal matrix and/or intraventricular hemorrhage (GMH/IVH Group), whereas 94 infants had studies that were negative (Non-hemorrhage Group). Serial neurodevelopmental assessments were performed on 142 (87%) of the 164 long-term surviving infants; these assessments included the Bayley Scales of Infant Development at 3, 6, 12, and 18 months (corrected age) and the Stanford-Binet and Peabody Picture Vocabulary examinations at 30 months (corrected age). At 30 months (corrected age), the incidence of major neurologic abnormalities was extremely low in both the GMH/IVH and the Non-hemorrhage groups. In addition, although there were few survivors of the more severe grades of intraventricular hemorrhage, we could detect no difference between the developmental scores of the GMH/IVH and the Non-hemorrhage Group infants.
