#x204E; p value < 0.05 is significant. TIH means tourniquet induced hypertension.

igure 3 Mean and SD of SBP between the 2 groups (∗ denotes significance between the 2 groups and # denotes significance compared to baseline value).

igure 4 Mean and SD of DBP between the 2 groups (∗ denotes significance between the 2 groups and # denotes significance compared to baseline value).

igure 5 Mean and SD of HR between the 2 groups (∗ denotes significance between the 2 groups and # denotes significance compared to baseline value).
