Statistical methods / analysis
Continuous data will be reported by mean +/- S.D. While categorical data by frequency and percentage. Continuous data will be compared between the three groups via analysis of variance(ANOVA) or kruskal-wallis test, depending on the normal distribution of data, determined by kolmgorov-Smirnov test. Categorical data will be compared between the three groups using chi- square test or fisher's exact test..Repeated measure ANOVA will be used to investigate the changes of the studied variables. P.value< 0.05 will be considered as statistically significant. Based on a pilot study on 10 patients subjected for laparoscopic cholecystectomy, it was calculated that 27 and 5 patients per group were required to detect a significant 20% inter group differences in mean arterial pressure and plasma cortisol level respectively. To compensate for possible droupouts , 35 patients per group were included.
