BACKGROUND Massive fetomaternal hemorrhage occurs in one in 1000 deliveries and has been associated with decreased fetal movements and a sinusoidal fetal heart rate (FHR) pattern. METHODS Three women presented with decreased fetal movements, nonreactive FHR patterns, and positive Kleihauer-Betke tests. All three were at a viable gestational age and were immediately delivered by cesarean. The three infants were severely anemic, with hemoglobin levels of 6.5, 5.3, and 5.1 g/dL, respectively. CONCLUSIONS A patient who presents with decreased fetal movement associated with a nonreactive FHR pattern and a positive Kleihauer-Betke test of more than 140 mL should be considered for immediate delivery if the gestational age is consistent with neonatal viability.
