A new application tool for the ROCHE pH electrode.

Using this tool the application of the pH electrode is nearly as easy as the attachment of a common ECG-scalp-electrode [3]. Visual control and lithotomy position is not necessary any more. The different tools are adapted to each other so that incision place and the tip of the pH electrode are automatically centered perpendicularly.

Continuous pH-measurement on anesthetized patients.

43 patients under general anesthesia were monitored by continuous tissue pH measurement and intermittent micro-blood-samples. The values obtained for the capillary pH and tissue pH were correlated. A highly significant correlation was found between tissular pH and capillary pH.

Continuous tissue pH measurement on the fetus during delivery.

Tissue pH values of 70 fetuses have been measured continuously during labor using the micro-electrode designed by Stamm. Significant correlation between continuous tissue pH and corresponding micro blood values can be shown. However, the relationship between patterns of tissue pH and capillary pH values seems not to be very constant.

[Frequency and distribution of breech presentation during pregnancy and labor (authors transl)].

On 975 pregnant women treated and delivered during 1973 at the Heidelberg University department of obstetrics 3780 ultrasound examinations were carried out. The frequency of breech presentation related to the duration of pregnancy and the likelyhood of breech presentation at term were calculated. Breech presentation can be seen as physiologic in 70% of early pregnancies.
