Abstract:Objective To study the application of oral 4 mL/kg and 10% glucose solution 2 hours before operation under the guidance of antral ultrasonography in gynecological laparoscopic surgery. Methods From January 2019 to August 2019, 60 gynecological patients who were to undergo laparoscopic surgery under general anesthesia in our hospital were selected and divided into oral sugar water group and conventional drinking ban group with 30 cases for each according to the random number table method. Conventional drinking ban group received routine fasting and drinking for 8 to 12 hours before operation, while oral sugar water group received routine fasting and oral administration of 4 mL/kg and 10% glucose solution 2 hours before operation. After entering the room, the cross-sectional area of gastric antrum (cross-sectional area, CSA) under two different postures was measured by ultrasound. The semi-horizontal position was CSA1 and the right lateral position was CSA2. Then the gastric volume (gastric volume, GV) and unit weight gastric volume (GV/weight, GV/W) were calculated by the formula; VAS score method was used to score thirst, hunger and anxiety of all patients 3 hours and 30min before operation respectively, and the difference between the two was further calculated; the postoperative first exhaust and defecation time of the two groups of patients were recorded. Results There was no significant difference in gastric antral cross-sectional area and predicted gastric volume between the oral sugar water group and the conventional drinking ban group (P > 0.05). Compared with the conventional drinking ban group, the VAS scores of thirst, hunger and anxiety in the oral sugar water group 30 min before operation were lower than those in the preoperative 3 h (P < 0.05). Compared with conventional drinking ban group, the first exhaust time in oral sugar water group was shortened (P < 0.05). Conclusion It is safe and feasible for antral ultrasonography to guide gynecologic laparoscopic surgery patients to take oral 4 mL/kg and 10% glucose solution 2 hours before surgery, which can alleviate patients’ subjective discomfort before surgery, shorten the first exhaust time after surgery and promote the early recovery of gastrointestinal function.
