Fetomaternal hemorrhage is a rare, potentially catastrophic event for a fetus. Leakage of the fetus's blood into the mother's circulation can cause fetal anemia, hydrops, and even death. The prevailing symptom is decreased fetal movement, and signs can include a sinusoidal electronic fetal monitor pattern, a positive Kleihauer-Betke test, or changes in fetal Doppler blood flow. A mother's report or perception of decreased fetal movement coupled with a nonreactive nonstress test or abnormal ultrasound findings should prompt an investigation into underlying causes.
Keywords: decreased fetal movement; fetal Doppler flow; fetomaternal hemorrhage; sinusoidal fetal heart rate.
