Randomized Controlled Trial Comparative Study Clinical Trial
Assessment of residual gastric volume and thirst in patients who drink before gastroscopy.
Before endoscopy patients undergo an uncomfortable fluid fast to reduce the risk of gastric acid aspiration and to ensure good endoscopic views are obtained. However, fluids rapidly leave the stomach and thus a long fluid fast before endoscopy may not be required. ⋯ It is safe for elective day cases to drink a significant volume of water two hours before endoscopy and this alleviates symptoms of thirst.
