Postoperative VAS scores for the study groups. L group (patients received 0.5% levobupivacaine plus 1-mL normal saline); LD50 group (patients received 0.5% levobupivacaine plus 50-µg dexmedetomidine); LD100 group (patients received 0.5% levobupivacaine plus 100-µg dexmedetomidine). The postoperative VAS score in the LD100 group was lower than that in the L group at 4 (p < 0.005), 6 (p < 0.001), 12 (p < 0.003), and 24 (p < 0.001) hours after surgery and was significantly lower than that in the LD50 group only at the 24th (p < 0.042) hour
