THE PURPOSE of this study was to observe directly the effects on the stomach of giving various fluids intravenously, especially those used frequently for intravenous feeding. These observations were made on the interior of the stomach of a 21 year old Negro woman, D. B., through a large gastrostomy opening 6 cm. in diameter.
METHOD OF PROCEDURE
The motility of the stomach was recorded by means of a rubber balloon (condom) which was connected through a glass tubing with a manometer filled with solution of sodium chloride which in turn was connected to a tambour for kymographic recording. Gastric juice was allowed to flow by gravity into a glass beaker by having the patient lie on her left side. Values for hydrochloric acid were obtained by titration with tenth-normal sodium hydroxide, Toepfer's reagent and phenolphthalein being used as indicators. Pepsin values were obtained by the Metz method. The blood flow was expressed as a color quotient, which was expressed
