Postoperative Sedation Score in the Two Studied Groups

Sedation score	Group A (n = 40)	Group B (n = 40)	P valuea,*
1	31 (77.5)	24 (60.0)	0.003
2	8 (20.0)	11 (27.5)
3	1 (2.5)	3 (7.5)
4	0 (0.0)	2 (5.0)
5	0 (0.0)	0 (0.0)

Values are presented as number (%). Group A received bilateral 0.2 mL/kg bupivacaine (0.125%; maximum volume 4 mL/side). Group B received bilateral 0.2 mL/kg bupivacaine (0.125%) + 0.5 μg/kg dexmedetomidine (maximum volume 4 mL/side).

^*P value < 0.05 was considered significant.

^aχ² test for trend was used to compare the proportion difference between groups.
