Brief Summary
Ultrasound-guided supraclavicular brachial plexus block (US-SCBPB) has been a generalized regional anesthesia in upper extremity surgery. It is performed just above the clavicle, in which the neural cluster formed by the trunks or divisions of the brachial plexus is situated superolateral to the subclavian artery (SA). In many approaches, corner pocket approach \[deposit local anesthetic (LA) at the intersection of the SA, neural cluster, and the first rib\] and cluster approach (direct deposit LA into the neural cluster after penetration of the sheath of brachial plexus) has been well known methods. And single or multiple injection techniques has been used with the above approaches.

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 1P1I group.
check 30 minutes after performing the block

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.
1P1I group
ACTIVE COMPARATORAfter subcutaneous injection of 1 mL of 2% lidocaine, 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 from lateral to medial direction. After the needle is penetrated the nerve sheath, the nerve stimulator is then turned on, and the stimulation current starts at 0.5mA. If hand muscle twitching is observed even at 0.3 mA, local anesthetics 30 mL (lidocaine mixed with epinephrine) is injected.
Interventions
2P2I group: nerve stimulating needle is advanced twice and LA is injected 15 mL at a time. 1P1I group: nerve stimulating needle is advanced once and LA is injected 30 mL.
2P2I group and 1P1I 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). 1P1I group is injected LA 30 mL at once.
Eligibility Criteria
You may qualify if:
- all patients anticipating surgery of the wrist or hand with aged 18 to 80 years and an American Society of Anesthesiologists physical status (ASA) of I or II.
You may not qualify if:
- patients with preexisting neuropathy in the operated limb, ASA greater than III, coagulation disorders, known allergy to local anesthetics, local infection at the puncture site, chronic obstructive pulmonary disease or respiratory failure, pregnancy, breast-feeding and prior surgery in the supraclavicular region, BMI ≥ 35 kg/㎡, uncooperative patients and patients' refusal. an ultrasound view of the perfect circular neural cluster.
