An interventional study of gum and candy in Gastroscopy, sponsored by Bursa Yüksek İhtisas Education and Research Hospital. Completed at 1 site in Turkey. Open to participants aged 18 Years to 70 Years. Per ClinicalTrials.gov, last updated 2025-04-15.

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.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Gastric volume
No washing was performed during the insertion and advancement of the endoscope. The entire gastric volume were aspirated into a scaled container (medbar collection container). The amount of collected samples was recorded .
Time frame: baseline
Gastric pH measurements
No washing was performed during the insertion and advancement of the endoscope. The entire gastric contents were aspirated into a scaled container (medbar collection container). The amount of collected samples was recorded and pH analysis (WTW inoLab® pH 7310 Table Type pH Meter) was performed.
Time frame: baseline
endoscopist satisfaction
At the end of the procedure, endoscopist satisfaction (0=unsatisfied 1=abstained 2=satisfied) and procedure difficulty (0=easy 1=normal 2=difficult)
Time frame: baseline
general procedure satisfaction
Before discharge, general procedure satisfaction (0=unsatisfied, 1=abstained, 2=satisfied), product satisfaction (0=unsatisfied, 1=abstained, 2=satisfied), product effects (1=increase in hunger, 2=increase in thirst, 3=increase in dyspepsia, 4=abstained, 5= decrease in hunger, 6= decrease in thirst, 7= decrease in dyspepsia)
