Preoperative Oral Carbohydrate Loading in Laparoscopic Gynecologic Surgery: A Randomized Controlled Trial

Study Objective: To determine whether carbohydrate loading improves the postoperative quality of recovery (QoR) better than the midnight fasting policy in laparoscopic gynecologic surgeries. Design: Randomized, parallel-group trial. Setting: Tertiary university hospital. Patients: Female patients scheduled for laparoscopic gynecologic surgery for nonmalignant gynecologic diseases. Interventions: Eighty-eight women were randomly assigned to the midnight fasting group (nil per os, NPO group) or the carbohydrate loading group (carbohydrate group). Patients in both groups adhered to the enhanced recovery after surgery protocol except for carbohydrate intake in the carbohydrate group. Measurements and Main Results: The postoperative QoR was evaluated using the QoR 15-item questionnaire on postoperative day 2. The times to readiness for discharge of the groups were compared. The QoR 15-item questionnaire scores were 97.7 +/- 23.0 in the NPO group and 99.6 +/- 22.4 in the carbohydrate group; they were not statistically different (p=.702). The times to readiness for discharge of both groups were also not different: 36.8 +/- 12.2 hours in the NPO group and 37.6 +/- 11.8 hours in the carbohydrate group (p=.684). Conclusion: The benefit of carbohydrate beverage intake was not significant in laparoscopic gynecologic surgeries when following the enhanced recovery after surgery protocol. (C) 2020 AAGL.

Automated summary

The study aimed to determine if carbohydrate loading improves postoperative quality of recovery in laparoscopic gynecologic surgeries compared to midnight fasting policy. Results showed no significant difference in postoperative QoR or readiness for discharge between the carbohydrate loading group and the midnight fasting group, indicating that the benefit of carbohydrate intake was not significant in laparoscopic gynecologic surgeries under the enhanced recovery after surgery protocol.
