[Premature separation of the placenta--clinical findings and fetal monitoring].

In a study group of 41 pregnant women of postpartally confirmed placental abruption, the prognostic value of clinical and diagnostic findings was investigated. The incidence of placental abruption was 1.4% of all deliveries within a three-year interval. 51% of patients showed vaginal bleeding before delivery. Retroplacental haematoma was found in 49% of cases ultrasonographically. A total of 75% had a pathological CTG test. More than 95% of these findings occurred within 3 days before delivery. Abnormal Doppler flow findings in foetal vessels more than 3 days before delivery were seen in 62% of cases. In the last three days before delivery, 86% were abnormal. Preterm delivery before 37 weeks of gestation was registered in 82% of patients. Perinatal mortality amounted to 12%. The rate of severely dystrophic newborn was 30%. Even in cases with lack of the clinical and/or sonographical findings, the possibility of placental abruption should be considered, if an acute deterioration of cardiotocographic or Doppler-sonographic findings.
