[Doppler score for evaluating perinatal risk].
Doppler sonography now has a definite place in the surveillance of risk pregnancies. Uniform clinical management is sometimes difficult especially in borderline cases. The following study demonstrates the possibility of standardizing and systematizing Doppler results using a score. In a collective of 253 pregnant women we performed Doppler examinations in the fetal aorta, umbilical artery, middle cerebral artery, internal carotid artery. The results were divided into 4 groups and correlated to the fetal outcome. There was a highly significant worsening in prognosis regarding duration of pregnancy, birth weight and rate of cesarean sections with increasing Doppler score. In the event of pathological and highly pathological scores, the average duration of pregnancy was 23 and 48 days shorter than normal. As a result, there was a highly significant reduction in the average birth weight compared to fetuses with normal Doppler scores: by 1060.7 g in the case of a pathological score and by 1633.5 g in the case of a highly pathological score. There was a highly significant correlation concerning the rate of cesarean sections and the indication "fetal distress". The average interval between diagnosis and birth was 6.3 days in the case of pathological Doppler findings and 2.3 days in the case of highly pathological findings. The difference was highly significant. In the case of highly pathological scores all fetuses were delivered after at least 5 days, compared with after at least more than 10 days in those with only pathological Doppler findings. This reflects the fact that there is none room for discretion in case of a highly pathological flow. In summary the Doppler score allows better estimation of fetal risk and can improve fetal prognosis by special monitoring and earlier obstetric intervention.
