Effect of Preoperative Oral Carbohydrate on Patients Undergoing Gynecological Laparoscopic Surgery With Different Fasting Times: A Randomized Control Study.

PURPOSE: This study aimed to investigate the effect of preoperative oral carbohydrates (POC) on patients undergoing gynecological laparoscopic surgery with different fasting times.

DESIGN

A randomized control study.

METHODS

Two hundred patients were randomly divided into F group (first operation without carbohydrates intake), S group (second operation without carbohydrates intake), Fpo group (first operation with POC intake), and Spo group (second operation with POC intake). The visual analog scale (VAS) of thirst and hunger, perioperative buffer excess (BE), electrolyte and glucose levels, as well as insulin resistance (IR) were compared. Time to first flatus, hospital stay, and eating time were also recorded.

FINDINGS: POC reduces the aggravation of thirst and hunger discomfort during the perioperative period. Abnormal perioperative BE and lactate levels were found in patients of F and S groups, while those in the Fpo and Spo groups almost returned to normal. Patients in all groups had preoperative hypokalemia, and those in the Fpo and Spo groups recovered quickly to normal intraoperatively. IR in patients in the Fpo and Spo groups retured to preoperative levels after surgery while, those in the F and S groups persisted until 48 hour postoperatively. No significant differences in postoperative nausea and vomiting, time to first flatus, time of first eating, and postoperative hospital stay were found among the four groups.

CONCLUSION

POC accelerates postoperative recovery in patients undergoing gynecological laparoscopy with different fasting times.
