Grade 2 placental abruption results in mild-to-moderate bleeding and some contractions of the uterus; grade 2 placental abruption can result in some fetal distress. Grade 1 placental abruption results in mild bleeding and some contractions of the uterus; however, there is generally only a small amount of pain and no extensive distress on the fetus. Grade 3 placental abruption results in severe bleeding and painful contractions of the uterus that often do not dissipate; grade 3 placental abruption often results in fetal death, according to Children's Hospital of Wisconsin.
Once placental abruption has occurred, there is no cure or way to reattach the placenta to the uterine wall. Oftentimes, depending on how far along the woman is in her pregnancy, the fetus can be retrieved via Cesarean section. Depending on the developmental level of the fetus, it is possible for the fetus to survive. According to Children's Hospital of Wisconsin, other risks for the mother involve heavy bleeding, for which it may be necessary to perform a blood transfusion, or hemorrhaging, a major risk factor when placental abruption occurs. Although placental abruption is mainly detectable once symptoms are already occurring, such as bleeding and cramping, the mother can help to reduce risks of placental abruption by avoiding certain health hazards, such as smoking. High blood pressure and a previous history of placental abruption can also add to a mother's risk factor.
