*Using independent sample test for mean VAS comparing two groups, **Using Univariate analysis test for mean VAS comparing two groups with adjusted of the use of additional drugs (Pethidine and Diclophenac), age, BMI, ***Used of repeat measure analysis test for mean VAS comparing during time each groups. VAS: Visual analog scale, BMI: Body mass index
