Treatment:

Treatment depends on various factors:

• How much bleeding you had
• Where the fetus is developed enough to survive outside the uterus
• How much of the placenta is covering the cervix
• The position of the fetus
• The number of previous births you have had
• Whether you are in labor

If the placenta is near the cervix or is covering a portion of it, you may be ordered reduce activities and stay on bed rest. Your doctor will order pelvic rest, which means no intercourse and no douching. Nothing should be placed in the vagina.

If there is bleeding, however, you will most likely be admitted to a hospital for careful monitoring.

If you have lost a lot of blood, blood transfusions may be given. You may receive medicines to prevent premature labor and help the pregnancy continue to at least 36 weeks. Beyond 36 weeks, the benefits of the infant maturing have to be weighed against the possibility of a major hemorrhage.

Your health care providers will carefully weigh your risk of ongoing bleeding against the risk of an early delivery for your baby.

Women with placenta previa most likely need to deliver the baby by cesarean section. This helps reduce mother and infant deaths. An emergency cesarean may be performed if the placenta actually covers the cervix and the bleeding is heavy or life threatening.

Expectations (prognosis):

Placenta previa is most often diagnosed before the mother or the fetus is in significant danger, so it no longer poses as much of a threat to babies and mothers as it once did.

The biggest risk is that severe bleeding will require your baby to be delivered preterm. Fetal distress doesn't usually occur unless there is a cord accident, or vaginal blood loss has been heavy enough to cause placenta abruptio or shock in the mother.

The outcome is excellent when the condition is managed properly. This means hospitalizing a mother who is having symptoms, and delivering by C-section.

Complications:

Risks to the mother include:

• Death
• Major bleeding (hemorrhage)
• Shock

There is also an increased risk for infection, blood clots, and necessary blood transfusions.

Prematurity (infant is less than 36 weeks gestation) causes most infant deaths in cases of placenta previa. Fetal blood loss or hemorrhage may occur because the placenta separates from the wall of the uterus during labor. The fetus also can lose blood when the uterus is opened during a C-section delivery.

Calling your health care provider:

Call your health care provider if you have bleeding from the vagina at any point in your pregnancy. Placenta previa can be dangerous to both you and your baby.
