Study Arms:
- group Levo-bupivacaine (Type: OTHER): Group A (20 patients): Anesthesia will be performed with 35 ml of 0.5% levo-bupivacaine plus 1ml normal saline under the guidance of ultrasound for infraclavicular brachial plexus block.
- group levo-bupivacaine plus 50µg dexmedetomidine (Type: OTHER): Group B (20 patients): Anesthesia will be performed with 35 ml of 0.5% levo-bupivacaine plus 50µg dexmedetomidine under the guidance of ultrasound for infraclavicular brachial plexus block.
- group levo-bupivacaine plus 100µg dexmedetomidine (Type: OTHER): Group C (20 patients): Anesthesia will be performed with 35 ml of 0.5% levo-bupivacaine plus 100µg dexmedetomidine under the guidance of ultrasound for infraclavicular brachial plexus block.
