Continuous intrapartum measurement of tissue pH of the human fetus using newly developed techniques.
Using a fiberoptic probe with a dye indicator, pH was studied in a group of 124 fetuses. Acidotic tissue pH was found to be a far more powerful indicator of fetal, neonatal and maternal problems than acidotic capillary blood pH. The tissue pH related more consistently to obstetric problems throughout labor. A comparison was made of the reliability of fetal acidotic tissue pH and acidotic capillary blood pH data in the identification and prediction of obstetric problems.
