33
Q

    • Excessive blood loss, leading to shock
    • Hidden (concealed) uterine bleeding in pregnancy
    • No labor
  • Fetal distress occurs early in the condition in about half of all cases
  • Infants who live have a 40-50% chance of complications, which range from mild to severe

Q

Placenta Abruptio: Prevention
