Abstract
BACKGROUND AND OBJECTIVES: Routine overnight fasting may increase the risk of postoperative complications and delay postoperative recovery. Oral carbohydrate drinks have been shown to reduce glucose utilization and postoperative negative nitrogen balance while preserving muscle mass and strength. This randomized controlled trial aimed to examine whether preoperative oral carbohydrate drinks can enhance postoperative physical recovery in patients undergoing major colorectal surgery. METHODS AND STUDY DESIGN: Seventy patients were randomly assigned to receive either a 12.5% oral carbohydrate drink or pure water. Patients in both groups received 800- mL of one of the drinks on the evening before surgery, and another 400-mL drink on the morning of the operative day. The primary outcomes were the distances covered in 2-minute-walk tests at 24, 48 and 72-hours and 6- minute walk tests at 7-10 days postoperatively. The secondary outcomes were the postoperative serum insulin and glucose concentrations, nitrogen balance, duration of hospital stay, and the patient satisfaction scores. RESULTS: There were no significant differences in the characteristics of the two patients-groups. The postoperative 2-minute and 6-minute walk test distances, serum insulin and glucose concentrations of both groups were not statistically different. Patients receiving carbohydrate drink had more positive nitrogen balance than the control group. The duration of hospital stay and patient satisfaction scores were similar for both-groups. CONCLUSIONS: There were no statistically significant differences in the postoperative walking capacities of patients receiving a carbohydrate drink or pure water; only the nitrogen balance on postoperative day 3 was higher for patients receiving the carbohydrate drink.
