BackgroundThe aim of this prospective, randomized, single-blinded study was to compare the effects of a carbohydrate drink 400 mL given 2 h before the surgery with preoperative overnight fasting on the gastric pH and residual volume, postoperative nausea and vomiting (PONV) and antiemetic consumption in patients undergoing laparoscopic cholecystectomy.Materials And MethodsForty American Society of Anesthesiologists physical status I-II patients who underwent elective laparoscopic cholecystectomy. Randomized, prospective, controlled study, Gulhane Medical Faculty and Guven Hospital Department of Anesthesiology and Reanimation. Patients were randomly assigned into two groups: Pre-operative carbohydrate drink group (group C, n = 20) and preoperative fasting group (group F, n = 20). Group C was given a 400 mL carbohydrate drink 2 h before to the surgery. The patients of group F were fasted 8 h before the surgery. Both groups were operated under general anesthesia with volatile anesthetics.ResultsHemodynamic parameters, demographic data, gastric acidity and residual volumes were similar for both groups. No complications were observed. PONV and antiemetic consumption was lower in group C compared to group F (P = 0.001). Patient's satisfaction was higher in group C (P < 0.001).ConclusionThis study showed that pre-operative carbohydrate drink may be used safely and also improves patient's satisfaction and comfort in patients undergoing laparoscopic cholecystectomy.
