Comparison of postoperative VAS score Groups A and B. VAS = visual analogue scale; VAS-1hr = visual analogue score at 1 hour, 2 hours, 3 hours, 4 hours, 6 hours, 8 hours, 12 hours, 24 hours, and 48 hours. Comparison of VAS score in Groups A and B. Until 12 hrs, patients did not complain of any pain in Groups A and B. After 12 hrs, Group B had a VAS score >4, and this difference in pain score was not statically significant with a p-value 0.086 at 24 hrs and 0.067 at 48 hrs.

Comparison of Mean Blood Pressure in Groups A and B. MAP = mean arterial pressure, MAP-0h = mean arterial pressure at baseline, MAP-15 min = mean arterial pressure at 15 minutes, MAP-30 min = mean arterial pressure at 30 minutes, MAP-1h = mean arterial pressure at 1 hour, MAP-2h = mean arterial pressure at 2 hours, MAP-4h = mean arterial pressure at 4 hours.
Figure 3 compares the mean arterial pressure. It was comparable at baseline in both groups but there was a statistically significant fall in mean arterial pressure at 30 min (p=0.000), 1 hr (p=0.010), and 4 hrs (p= 0.028) from baseline in Group A compared to Group B.
