Abstract
We investigated platelet count, bleeding time, platelet aggregation, prothrombin time, activated partial thromboplastin time, and fibrinogen level in 58 very low-birth-weight infants during the first postnatal day to determine the relationship between hemostatic disorders and intraventricular hemorrhage. Thirty-two of the 58 infants (55%) were found to have periventricular-intraventricular hemorrhage by computerized tomography or autopsy. Nine patients (16%) had subarachnoid hemorrhage only and 17 (29%) had no evidence of intracranial hemorrhage. Infants with IVH had a significantly lower mean platelet count than did infants with no SAH/IVH. However, only five patients with IVH had initial thrombocytopenia. The IVH group had a mean bleeding time which was significantly prolonged compared to that of the group without SAH/IVH. Similarly, patients with IVH had a mean platelet aggregation response which was significantly diminished in comparison to that of patients with no SAH/IVH. Infants with IVH had a significantly longer mean PT than did infants with no SAH/IVH. In addition, babies with IVH had a significantly longer mean APTT compared to that of babies without SAH/IVH. The groups did not differ significantly with respect to fibrinogen levels. Three infants with IVH had disseminated-intravascular coagulation in the early neonatal period. These data suggest that disorders of platelet-capillary interaction and defects in the intrinsic and extrinsic coagulation pathways may play important roles in intraventricular hemorrhage in the premature infant.
