Preoperative fasting beginning the day before surgery has been standard practice to prevent aspiration pneumonia associated with general anesthesia [1]; thus before surgery, the patients are inevitably exposed to dry month and hunger. In Japan, preoperative fluid and electrolyte management is usually performed by intravenous therapy, and the fasting time prior to surgery seems to be longer than in other countries [2]. However, due to a lack of sufficient scientific evidence [1], the period of preoperative fasting has recently been reevaluated, and societies of anesthesiology in the United States and most European countries have revised the practice guidelines for preoperative fasting so that the oral intake of clear fluids may be permissible up to 23 h before surgery in selected surgical patients (excluding those in whom delayed gastric emptying is suspected) [3].In addition, an approach for minimizing surgery-related stress and reducing subsequent complications has been introduced by Fearon et al. as the “enhanced recovery after surgery” (ERAS) protocol, addressing the disadvantage of preoperative fasting [4].
