Placental abruption is most likely to occur in the last trimester of pregnancy, especially in the last few weeks before birth. Classic signs and symptoms of placental abruption include: Vaginal bleeding. Abdominal pain. Back pain. Uterine tenderness. Rapid uterine contractions, often coming one right after another.
A placental abruption (abruptio placentae) is when a normally implanted placenta separates from the uterus after 20 weeks gestation (less then 20 weeks gestation is considered a spontaneous abortion). It occurs in approximately 0.5-1% of pregnancies in North America (Broers et al, 2004).he classical presentation is that a placental abruption is painful bleeding and a placenta previa is painless, however a woman with a placenta previa can also be contracting and thus can be in pain as well. A pelvic exam should not be done until a placenta previa can be ruled out as this can trigger further bleeding.
