<p>A specially formulated beverage composition designed to be ingested by a pre-operative patient at least about 2 hours prior to administration of anesthesia is provided herein. The beverage composition is preferably provided in a single-serving volume containing at least about 200 Calories, which Calories are primarily from a non-protein, non-fat source, such as one or more carbohydrates. In a most preferred embodiment, the composition includes about 48 grams maltodextrin, about 6 grams fructose and about 6 grams glucose, in water with enough citric acid to provide a final solution pH of about 4.3. This beverage composition, when ingested during pre-operative fasting, at least about 2 hours prior to administration of anesthesia, encourages compliance with pre-operative fasting requirements; reduces the incidence of symptoms associated with prolonged fasting, such as feelings of hunger and thirst, lightheadedness, irritability and headache; and should reduce the risk of aspiration pneumonia by providing a residual gastric volume and gastric pH within generally accepted ranges. Also, contemplated herein is the method of using this beverage composition to increase compliance with pre-operative fasting guidelines and thereby decrease the risk of aspiration pneumonia in the anesthetized/sedated patient.</p> |
