Placenta abruptio is separation of the placenta (the organ that nourishes the fetus) from the site of uterine implantation before delivery of the fetus.
The exact cause of a placetal abruption may be difficult to determine.
Direct causes are rare, but include:
Risk factors include:
Placenta abruptio, including any amount of placental separation prior to delivery, occurs in about 1 out of 150 deliveries. The severe form, which results in fetal death, occurs only in about 1 out of 500 to 750 deliveries.
Tests may include:
Treatment may fluids through a vein (IV) and blood transfusions. The mother will be carefully monitored for symptoms of shock and the unborn baby will be watched for signs of distress, which includes an abnormal heart rate.
An emergency cesarean section may be necessary. If the fetus is very immature and there is only a small placenta rupture, the mother may be kept in the hospital for close observation and released after several days if the condition does not get worse
If the fetus is developed (matured) enough, vaginal delivery may be chosen if there is minimal distress to the mother and child. Otherwise, a cesarean section may be the preferred choice.
The mother does not usually die from this condition. However, the following increase the risk for death in both the mother and baby:
Fetal distress appears early in the condition in about half of all cases. The infants who live have a 40-50% chance of complications, which range from mild to severe.
Excessive loss of blood may lead to shock and possible death in the mother or baby. If bleeding occurs after the delivery and blood loss cannot be controlled by other means, a hysterectomy (removal of the uterus) may become necessary.
Call your health care provider if you are in an auto accident, even if the accident is relatively minor.
See your health care provider immediately, call your local emergency number (such as 911), or go to the emergency room if you are pregnant and have symptoms of this condition. Placenta abruptio can rapidly become an emergency condition that threatens the life of both the mother and baby.
Avoid drinking, smoking, or using recreational drugs during pregnancy. Get early and continuous prenatal care.
Early recognition and proper management of conditions in the mother such as diabetes and high blood pressure also decrease the risk of placenta abruptio.
