Data presented as mean ± SD or n of patients (%).
aNormally distributed continuous variables were compared using Student’s t-test; continuous variables that were not normally distributed were compared using Mann–Whitney U-test; categorical variables were compared using χ2-test.
VAS, visual analogue scale; PACU, postanaesthesia care unit; ICU, intensive care unit; PONV; postoperative nausea and vomiting; NS, no significant between-group differences (P > 0.05).
