I ntraventricular hemorrhage (IVH) is a major neurological problem in preterm neonates. 5, 24, 31 Little is known of the pathophysiological mechanisms involved and the effect of IVH on the neuro-developmental outcome of these patients. Although some information is being obtained about cerebral blood flow (CBF) in animal models involving preterm neonates with IVH and in the infants themselves, little is known about the effect on cerebral metabolism of this patient population from the profound hypoglycorrhachia that occurs for many days following IVH. 26, 44

I ntraventricular hemorrhage (IVH), or hemorrhage into the germinal matrix tissues (GMH) of the developing brain, 20 is a major neurological problem of preterm neonates, 60 and has been found in over 40% of all preterm neonates with a birth weight of 1500 gm or less. 11, 43 Thought to be secondary to alterations in cerebral blood flow (CBF) to the preterm cerebrum, 4, 29, 36 IVH has also been associated with changes in cerebral metabolism, 30, 59 and both the alterations in CBF and the metabolic changes may contribute to the later neurodevelopmental
