title: Chronic massive fetomaternal hemorrhage: a case report.
abstract: We report a case of massive chronic fetomaternal hemorrhage with remarkable fetal compensation. The labor course was complicated by a fetal heart rate pattern showing decreased long- and short-term variability and the eventual development of persistent late decelerations. The fetal scalp blood pH and cord blood pH values were normal. A living male infant was delivered by cesarean section for persistent late decelerations. A Kleihauer-Betke stain on a maternal blood sample was positive at 14.5%, which is equivalent to 700 mL of fetal blood in the maternal circulation.
