About

Oral carbohydrate loading until 2 h before surgery is well known to be effective in facilitating postoperative recovery and reducing complications, by maintaining homeostasis. However, there are still concerns in implementing this as a universal fasting guideline, because of the risk of pulmonary aspiration. Therefore, we designed this study to compare the two preoperative fasting guideline: (1) keep fasted from midnight until surgery, and (2) oral carbohydrate beverage 800 mL from midnight until 2 h before surgery.
