[Clinical experiences of continuous pH measurements on the fetus during delivery (author's transl)].

Under clinical observation 22 continuous measurements of tissue pH were carried out according to Stamm's method, causing a number of questions, such as usability, possible faults and susceptibility to trouble. Testing the accuracy of measurements was a decisive factor, i.e. conformity of blood pH (determined intermittently according to the conventional method) with tissue pH was tested according to the new method. Furthermore, these values were compared to gas analytical findings in artery and vein of the umbilical cord of the new borns.
