Abstract

A randomized, controlled clinical intervention study was conducted on 70 patients undergoing gynecologic laparoscopic surgery. The patients were divided into two groups: the CHO group intaked 600 ml of a 15% maltodextrin solution the night before surgery and an additional 300 ml of the same solution up to 2 hours before surgery, while the FAST group fasted overnight according to standard protocol. Gastric residual volume (GRV) was assessed via antral ultrasound before anesthesia, and gastric pH was measured using the PH8414 pH meter (Total Meter brand) after anesthesia induction. Results: Gastric residual volume did not differ significantly between the two groups (p = 0.57; 22.6 ml in the CHO group vs. 15.7 ml in the FAST group). The Perlas ultrasound grading of gastric residual volume also showed no significant difference (p = 0.42). No patients experienced aspiration during anesthesia induction. The gastric pH in the CHO group was higher than in the FAST group (3.34 vs. 2.99), but the difference was not statistically significant (p = 0.11). Conclusion: Intaking 300 ml of a 15% maltodextrin solution 2 hours before anesthesia induction is safe, does not increase gastric residual volume, and does not significantly reduce gastric pH in patients undergoing gynecologic laparoscopic surgery.
