None of the studies received industry support, and 1 study noted author conflict of interest. Healthy adult patients should be encouraged to drink up to 400ml of carbohydrate-containing clear liquids until 2h before an elective procedure to minimize potential harms of prolonged fasting, including hunger and thirst. Clinical significance of pulmonary aspiration during the perioperative period. Do not routinely administer preoperative gastrointestinal stimulants for the purpose of reducing the risk of pulmonary aspiration in patients with no apparent increased risk for pulmonary aspiration.
