An evaluation of a continuous tissue pH monitor in the fetal and neonatal goat.
The validity of continuous tissue pH measurements was established in the fetal and neonatal goat model. Simultaneous determinations of tissue, arterial, and venous pH were done during alterations in acid-base status. A highly significant correlation was found between tissue and blood pH levels (r = 0.89, p less than 0.001). These data confirm the accuracy of the tissue pH instrumentation in predicting core blood pH status and support the potential usefulness of the instrumentation in perinatal medicine for continuous fetal acid-base monitoring.
