Background and objective We studied the effect of three different fasting protocols on preoperative discomfort and glucose and insulin levels. Methods Two hundred and ten ASA I-III patients undergoing general or gastrointestinal surgery were randomly assigned to three groups: overnight intravenous 5% glucose infusion (1000 ml), carbohydrate-rich drink (400 ml) at 6-7 a.m., or overnight fasting. The subjective feelings of thirst, hunger, mouth dryness, weakness, tiredness, anxiety, headache and pain of each patient were questioned preoperatively using a visual analogue scale. Serum glucose and insulin levels were measured at predetermined time points preoperatively. Results During the waiting period before surgery, the carbohydrate-rich drink group was less hungry than the fasting group (P=0.011). No other differences were seen in visual analogue scale scores among the study groups. Trend analysis showed increasing thirst, mouth dryness and anxiety in the intravenous glucose group (P<0.05). The carbohydrate-rich drink group experienced decreasing thirst but increasing hunger and mouth dryness (P<0.05). In the fasting group, thirst, hunger, mouth dryness, weakness, tiredness and anxiety increased (P<0.05). Both intravenous and oral carbohydrate caused a significant increase in glucose and insulin levels. Conclusion Intravenous glucose infusion does not decrease the sense of thirst and hunger as effectively as a carbohydrate-rich drink but does alleviate the feelings of weakness and tiredness compared with fasting, Euro J Anaesthesiol 26:123-127 (c) 2009 European Society of Anaesthesiology.
