[The development of children born by vaginal or abdominal breech delivery (author's transl)].

The early and late development of children born by the breech either by vaginal breech delivery or by caesarean Section is compared. The early and late morbidity of the two groups is discussed in detail. Considering the recently published data by Hagberg (6) theinterpretation of findings classified as secondary morbidity is very dificult.

The effect of modern intensive monitoring in obstetrics on infant mortality and the incidence of hypoxia and acidosis.

Unlabelled: We consider intensive monitoring to be fetal monitoring during labor and in the newborn period of all births using the most efficient methods. During the last ten years we have sequentially used the following techniques: Amnioscopy, blood analysis, estrogen determinations in urine, external and internal cardiotokography and internal pressure determinations, gas analyses of umbilical blood. amniotic fluid analyses (phospholipids), ultrasound (B-apparatus) and HCS determinations.

[Is a vaginal breech delivery still justified? (author's transl)].

In our series of vaginal breech deliveries the morbidity from hypoxia and acidosis showed no difference to the same type of morbidity in our series of breech deliveries by Caesarean section. The correct selection of cases, intensive monitoring during labour and the management of the second stage of labour as outlined in our paper are the most important perequisites which permit to plan and justify a vaginal breech delivery in present obstetric practice.
