Massive fetomaternal hemorrhage.

This report describes a full-term newborn with massive fetomaternal hemorrhage. Fetal movements were decreased 48 hr prior to delivery. On the day of delivery, they were absent. The nonstress test was abnormal with low biophysical profile and decreased beat-to-beat variability. The infant presented with extreme pallor, hypotonia, hepatosplenomegaly, and ascites. The initial hemoglobin was 2.2 g/dL, the Kleihauer-Betke stain was 27.6% (highest level ever reported). Right temporal and cerebellar hemorrhages were present. Sequelae include severe developmental delay and asymmetric double hemiplegia.
