Fetal blood loss from placenta

Definition

Fetal blood loss can result from placental abruption, which is when the placenta separates from the uterine wall prior to delivery. Placental abruptions occur under conditions of maternal hypertension and drug use (e.g. cocaine), maternal vascular and collagen vascular disease, maternal clotting disorders, and following direct abdominal trauma. Fetal blood loss can also result from accidental incision of the placenta during a caesarean section.
