The study population comprised 66 patients diagnosed with gastric adenocarcinoma, who were randomly assigned to either group A or group B. Patients in group A consumed 200\u2005ml of 5% dextrose solution 2\u2005h prior to the operation, and patients in group B consumed 400\u2005ml of 5% dextrose solution 2\u2005h prior to the operation. gastric contents were suctioned through a gastroscope immediately after endotracheal intubation.
