Abstract
THE recent availability of cation-exchange indicator compounds has suggested their use in determining the presence or absence of free hydrochloric acid in gastric contents without the need for intubation of the stomach.1 , 2 The purpose of this preliminary report is to present our experiences with this test in comparison with the conventional tube method of gastric analysis, and to outline the indications and limitations of the tubeless technic.RationaleThe cation-exchange indicator compound Diagnex§ is prepared by replacing the hydrogen cation of a carboxylic acid group, present in the exchange resin, with a quininium cation. As demonstrated by in vitro and . . .Keywords
