During the period 1969--1973, a total of 7933 deliveries was carried out at the First University Clinic of Obstetrics and Gynaecology in Vienna. Of these, 328 deliveries were breech presentations and 260 were single-born. The frequency of Caesarean sections in the case of breech presentations was 16,6%, i.e. about four times higher than the average frequency of Caesarean sections in relation to the overall number of obstetric patients of our clinic. The high frequency of premature deliveries in breech presentation (18,46%) is reflected in the perinatal mortality rate; 5,67% of all children born in breech position died sub or post partum. The net perinatal mortality rate was 1,15%.
1969年至1973年期间，维也纳第一大学妇产科诊所共进行了7933例分娩。其中，328例为臀位分娩，260例为单胎分娩。臀位分娩的剖宫产率为16.6%，即比我们诊所产科患者总数的剖宫产平均率高出约四倍。臀位分娩早产的高发生率（18.46%）反映在围产期死亡率上；所有臀位出生的儿童中有5.67%在分娩时或产后死亡。净围产期死亡率为1.15%。
