title: Preoperative fasting after soft drink intake: 2 hours may be enough.
abstract: Sufficient preoperative fasting time is essential for safe induction of anesthesia to prevent aspiration of gastric contents. However, the time recommended for sufficient preoperative fasting varies greatly, depending on the nature of the oral intake, from 2 h for clear liquids to 6 h for solid foods. We report the case of a 30-year-old man who drank about 600 ml of the carbonated, glucose-rich soft drink, 7-UP, 2 h before surgery and absorbed nearly all of it within these 2 preoperative hours.
