The incidence increases with each pregnancy , and it is estimated that the incidence in women who have had 6 or more previous deliveries may be as high as one in 20 births. Fetal distress is not usually present unless vaginal blood loss has been heavy enough to induce maternal shock , placenta abruptio occurs, or unless a cord accident occurs. An abdominal ultrasound indicates low positioning of the placenta. Early in pregnancy, transfusions may be given to replace maternal blood loss and medications given to prevent premature labor, prolonging pregnancy to at least 36 weeks. Beyond 36 weeks, the benefits of additional infant maturity have to be weighed against the potential for major hemorrhage.
Cesarean section is the preferred method for delivery.
It has proven to be the most important factor in reducing maternal and infant death rates. This rate may be reduced with ideal obstetrical and newborn care available at major medical centers. Maternal complications include major hemorrhage, shock , and death. Fetal blood loss or hemorrhage may occur because of the placenta tearing away during labor. It may also occur with entry into the uterus during a C- section delivery.
