On the basis of our own experience and the literature the risk of acidosis, which corresponds to the risk of asphyxia, during vaginal delivery of breech presentations is examined. Compared with delivery of vertex presentation it is 3-10 times greater. The risk of acidosis does not depend on the duration of pregnancy and only a little on the parity of the mother. Even with carefully selective indication for primary Caesarean section it cannot be reduced below the high level. Typically there is acute compression of the cord at the end of the first or later stages of labor. Even with intensive intra-partum care it cannot safely be predicted with sufficient certainty. As a criterion of the efficiency of modern obstetrics the impact of acidosis in umbilical blood and its increase in breech presentation is discussed. Only systematic Caesaren section before or early in labor will lower the risk to that of vertex presentation. This is done and recommended by the authors. Links between acdosis in umbilical blood and permanent cerebral damage are probable but by no means certain and their importance in unknown. Selective indication for Caesarean section which has to be made generously, represents an acceptable alternative.
根据我们自己的经验和文献，对臀位阴道分娩时酸中毒风险（与窒息风险相对应）进行了研究。与头位分娩相比，其风险要高3至10倍。酸中毒风险不取决于孕期长短，且仅在很小程度上取决于产妇的产次。即使仔细选择剖宫产指征，也无法将其降低至低水平以下。通常在第一产程末或之后的阶段会出现脐带急性受压。即使加强产时护理，也无法足够确定地安全预测。作为现代产科学效率的一个标准，讨论了脐血酸中毒的影响及其在臀位分娩中的增加情况。只有在分娩前或分娩早期进行系统性剖宫产，才能将风险降低至头位分娩的水平。作者就是这样做并推荐的。脐血酸中毒与永久性脑损伤之间可能存在联系，但绝非确定无疑，其重要性也尚不清楚。必须广泛进行的剖宫产选择性指征是一种可接受的选择。
