Placenta abruption is the separation of the placenta from the uterine wall before the baby is born. Alternate names are placental abruption and placental abruption.

In most pregnancies, the placenta remnants firmly attached to the upper part of the wall of the uterus. In one of the 150 pregnancies - usually during the third trimester - detach the placenta from the uterine wall prematurely, causing bleeding. Usually only a part of the placenta separates; other times it withdrew completely.

The placenta is the lifeline of the fetus, and if it becomes detached, it is a serious problem. Placental abruption reducing the supply of oxygen and nutrients to the fetus, making it one of the leading causes of death of the fetus in the third trimester. However, more than 90% of their babies survive placenta abruption. maternal deaths are rare.

No one understands fully what causes placental abruption, but women with chronic high blood pressure have the highest risk. Other risk factors include heart disease, diabetes, smoking, and alcohol or cocaine use. Women who are African American, older than 40, or have a previous placental abruption are also more likely to experience it. Injury to the mother, such as a car accident, also can cause abruption.

The most common symptoms are vaginal bleeding and painful contractions. The amount of bleeding depends on how much of the placenta has separated.

Sometimes the blood accumulates between the placenta and the uterine wall, so there is no visible bleeding from the vagina. Be aware of other symptoms, such as abdominal cramping or severe pain, back pain, and reduced fetal movements.

If you notice any of these symptoms or any kind of vaginal bleeding during pregnancy, contact your health care provider immediately.

The evaluation begins with a physical examination. The doctor will also observe your uterine contractions and fetal responses to them. You may also have an ultrasound; However, only half of abruptios placenta can be detected this way (For information on what to expect from a.

If you are a small separation of the placenta, your health care provider may suggest bed rest to stop the bleeding. After a few days, you usually can resume your normal activities.

If the moderate separation occurs, you may have to stay in the hospital so your medical team can carefully observe you and your fetus. Your doctor may use electronic monitoring to see the fetal heartbeat. You may need a blood transfusion. If the fetus shows signs of distress, the doctor can lead to early delivery. If you are not able to give birth vaginally, the doctor will perform a c-section (cesarean).

A severe placental separation is an emergency. Your doctor will give your baby immediately - usually by c-section - if there are signs that your baby is in trouble. In about 1 in 800 pregnancies, placental abruption causes a stillbirth.

While placental abruption can not be prevented, your best bet is to keep the conditions associated with it - high blood pressure, heart disease, and diabetes - under control. You can reduce your risk by avoiding tobacco, alcohol, and cocaine. If you already have an abruption in a previous pregnancy, talk to your doctor about the possible prevention strategies.

Q: What is the difference between placental abruption and placenta previa?

A: With placental abruption, the placenta partially or completely detach from the uterine wall before delivery. With placenta previa, the placenta is located over or near the cervix, in the lower part of the uterus. Patients with placenta abruption usually experience painful contractions with bleeding, while those with placenta previa bleeding painful experience. In both cases, you are more likely to have a c-section. Both of these conditions can cause bleeding deep and can harm the mother and fetus if not treated promptly. However, with ultrasound and fetal heart rate monitoring, both conditions can usually be managed successfully.
