Clinical evaluation of tissue pH monitoring during labor. Second series of 61 cases.
A newly developed tissue pH electrode designed for continuous pH monitoring was evaluated in 61 fetuses during labor. The results obtained in this series confirm the reliability of this method. The correlation coefficient between tissular pH and capillary blood pH is 0.94. The correlation coefficient between the last intrapartum tissue pH and the umbilical arterial blood pH is 0.84.
