[Analysis of 65 cases of abruptio placenta]

From Jan 1, 1971 to Dec 12, 1990, 65 cases of abruptio placenta were admitted to our hospital. The incidence was 0.19%. Among them, thirty were complicated by pregnancy induced hypertension (46.2%). The perinatal fetal mortality was 19.7%; perinatal death occurred mostly in the premature group. All babies survived except two abnormalities. Cesarean section rate was 32.3%. All postpartum hemorrhage 29.2%. Couvelaire uterus 6.2%, were cured by conservative treatment. There was neither stillbirth nor newborn death in the thirty three cases treated expectant, but a newborn asphyxia rate of 6.1% and a cesarean section rate of 15.1%. Analysis showed that abruptio placentae should be suspected in cases with abnormal fetal heart rate of unknown cause accompanying signs of labor, premature labor of unknown cause, uterine tongue, ultrasonically visualized liquid from dark area behind the placenta, besides classical signs of abdominal pain and vaginal bleeding. Expectant treatment is appropriate if gestational age is small and no acute symptoms exists so as to minimize the perinatal mortality and cesarean section rate.
