Development of a special electrode for continuous subcutaneous pH measurement in the infant scalp

Am J Obstet Gynecol. 1976 Jan 15;124(2):193-5. doi: 10.1016/s0002-9378(16)33297-5.

Abstract

Using a combined special glass electrode it is possible to monitor pH ratios and pH variation in the subcutaneous tissue of the infant scalp continuously. Tests on a normal sample of newborn babies immediately after birth showed a significant correlation between tissue pH and capillary blood pH, with the trend of pH variation being broadly similar in both measurement media.
