  Background: Preoperative fasting of clear fluids is recommended to reduce the incidence of pulmonary aspiration under anesthesia but non-compliance may cause aspiration or an inconvenient delay in surgery. Safe reduction of fasting time below the current standard of 2 hours has been reported but has not been demonstrated clinically. The aim of this study was to determine if reducing the fast of clear fluids to 1 hour increases residual gastric volume. Methods: 181 adult patients scheduled for gastroscopy at three sites were randomized to receive 200 ml of water either 80-150 (Standard Fast group) or 40-75 minutes (Short Fast group) before anesthesia. Patients were stratified to current proton pump and antacid therapy. Gastric contents were aspirated under vision by gastroscopy after induction of anesthesia and the volume and pH were compared..
