Continuous measurement of tissue pH in the human fetus.
The ROCHE pH electrode was tested clinically in 20 fetuses and one nonviable newborn with severe malformations. The proper fixation of the electrode in the fetal scalp is difficult. In the physiologic pH range a good correlation between capillary blood pH and tissue pH exists. The situation is less clear for the acidotic range.
