Evaluation of Gastric Volume and pH Changes in Gastroscopy Patients

Evaluation of Gastric Volume and pH Changes in Gastroscopy Patients Using Chewing Gum and Candy: Prospective Randomized Double-Blind Study

Pulmonary aspiration is a rare but serious complication that can result in 57% mortality and 14% permanent damage. Fasting rules (solid foods 6-8 hours, clear liquids 2 hours) determined by anesthesia associations are applied to prevent pulmonary aspiration by reducing gastric volume. Gastric volume (≥ 0.5 mL/kg) and pH (<2.5) values are shown to be determinants in the occurrence of pulmonary complications .

The hypothesis of this study was that preprocedure candy and chewing gum use may have no effects on gastric residual volume and pH. For this purpose, we analyzed the gastric residual volume and gastric pH values of patients who were given gum and candy before the procedure.
