Brief Summary
The supraclavicular block can provide effective surgical anesthesia of the forearm and hand. There have been many different approaches to ultrasound-guided supraclavicular brachial plexus block (US-SCBPB) according to the needle injection site (e.g. corner pocket approach, cluster approach) or number of needling (single or double injection). Numerous studies demonstrates good results (e.g. faster onset time) when using double injections rather than single injection. But double injection does not guarantee complete sensory block because ulnar nerve tends to be spared by its anatomical location.

Outcome Measures
Primary Outcomes (1)
rate of complete sensory blockade of all 4 nerves
If the sensory on the site under the control of all 4 (median, radial, ulnar, musculocutaneous) nerves is checked as 0 (just feeling of touch or none ) separately, it is considered as a complete sensory block. the investigators compare the rate of complete sensory block with 2P2I group and 1P2I group.
check 30 minutes after performing the block at 5-minute intervals (from date of randomization until the date of first documented progression)
Secondary Outcomes (1)
the onset time
check 30 minutes after performing the block at 5-minute intervals(from date of randomization until the date of first documented progression)
Study Arms (2)
2P2I group
EXPERIMENTALsubcutaneous injection is done widely. A nerve stimulating needle (Stimuplex insulated needle; D Plus B. Braun, Melsungen, Germany) attached to a nerve stimulator (Stimuplex HNS12; B. Braun, Melsungen, Germany) is advanced via an ultrasound in-plane approach. After the needle is penetrated the nerve sheath with a direction of downward, the nerve stimulator is then turned on. If hand muscle twitching is observed even at 0.3 mA, LA 15 mL (lidocaine mixed with epinephrine) is injected. After that, the stimulating needle is re-advanced at the behind site of the initial puncture site. And the needle is penetrated the nerve sheath with a direction of upward, and then the same process is performed and LA 15 mL is injected.
1P2I group
ACTIVE COMPARATORsubcutaneous injection is done widely. A nerve stimulating needle (Stimuplex insulated needle; D Plus B. Braun, Melsungen, Germany) attached to a nerve stimulator (Stimuplex HNS12; B. Braun, Melsungen, Germany) is advanced via an ultrasound in-plane approach. After the needle is penetrated the nerve sheath with a direction of downward, the nerve stimulator is then turned on. If hand muscle twitching is observed even at 0.3 mA, LA 15 mL (lidocaine mixed with epinephrine) is injected. After that, the stimulating needle is re-advanced with a direction of upward at the same puncture site and penetrated the nerve sheath. If hand muscle twitching is observed at 0.3 mA, LA 15 mL is injected.
Interventions
2P2I group: nerve stimulating needle is advanced twice with the up-down direction at the different puncture site and LA is injected 15 mL at a time. 1P2I group: nerve stimulating needle is advanced twice with the up-down direction at the same puncture site and LA is injected 15 mL at a time.
2P2I group and 1P2I group use the same LA (1.5% lidocaine mixed with 1:200,000 epinephrine). But 2P2I group is injected LA at equally divided doses (15 mL at a time) with the up-down direction at the different puncture site. 1P2I group is injected LA at equally divided doses with the up-down direction at the same puncture site.
