Abstract
Objective The aim of this study is to investigate the effect of preoperative carbohydrate loading (CHO) on perioperative body temperature of gynaecological patients with general anesthesia. Methods Sixty female patients undergoing surgery were randomized to either fasting overnight (FAST group) or receive 800 ml of CHO in the evening before and 400 ml of CHO 2 h before anesthesia (CHO group)(n=30). Perioperative body temperatures (induction of anesthesia, after anesthesia 15, 30, 45, 60 min and the end of surgery) and degree of shivering were recorded. Results The basal temperature was not significantly different between two groups(P>0.05). The FAST group showed a significantly greater decrease in temperature from the baseline than the CHO group(P<0.05). Postoperative shivering scores of patients in FAST group is significantly higher than scores of patients in CHO group(P<0.05). Conclusions Preoperative carbohydrate loading reduces hypothermia in gynaecological patients under general anesthesia. Key words: Carbohydrate; Pretreatment; Perioperative; Hypothermia; Shivering
