Figure 2.

Trend of nausea score (according to VAS) was indicated before and after of interventions in laparoscopic cholecystectomy patients. There was statistically significant time (P < 0.001), group (P < 0.001), and interaction (P < 0.001) effects. In post-hoc analysis: * and ** indicate significant difference in nausea score (P < 0.05 and P < 0.001 respectively) between dextrose and control group. (1: Immediately after post-anaesthesia care unit arrival; 2:30 min after post-anaesthesia care unit arrival; 3:60 min after post-anaesthesia care unit arrival; 4:90 min after post-anaesthesia care unit arrival; 5:120 min after post-anaesthesia care unit arrival; 6:6 h after surgery; 7:12 h after surgery; 8:24 h after surgery)
