The etiology of intraventricular hemorrhage (IVH) in extremely low birth weight preterm infants is multifactorial with circulatory instability and hemostasis being preeminent. This study sought to determine if the germinal matrix layer remained intact when platelets were above 200 × 109/L, a near normal level, and fell below that when IVH occurred. This was a retrospective study of platelets and head ultrasounds (HUS) in infants 23–28 weeks gestation. Analyses were descriptive, one way analysis of variance, Pearson Chi-square tests, and t-tests. Platelet counts and HUS were linked in 114 infants during the first 3 days when 90% of IVHs occur. Mean platelet levels were >200 × 109/L in 68% of infant 23–24 weeks gestation and 78% of those 25–26 weeks when there were no IVHs. These findings, if confirmed, suggest that improving hemostasis in high risk preterm infants by keeping platelet levels >200 × 109/L may maintain the integrity of the germinal matrix layer and prevent IVHs.
