[pH measurements following delivery from breech presentation (author's transl)].

In 1977 the adaptation capability of 22 out of 89 breech presentation new-borns was studied by way of punctual pH-measurements within the first 30 minutes after birth. Thus, it was possible to gain an insight into the extra-uterine adaptation, especially with respect to the mode of delivery. Further points of comparison were parity, maturity and a possible correlation with the Apgar Score. The study included a comparison with identical measurements of 20 spontaneous head position new-borns. According to the results under certain preconditions a vaginal delivery in breech presentation is also today by all means to be justified.
