[A titration method of determining the acidity of opaque gastric juice in emergency surgery]

The data presented show great practical significance of titration methods of the investigation of gastric secretion. 220 comparative determinations of acidity of the gastric juice have shown the presence of admixtures of mucus, blood and bile in the gastric content to overstate the indices of the colorimetric titration method without a practical effect on the electrometric one which is known to be more precise.
