Brief Summary
This study will test the hypothesis that sequential injection of 1.5% mepivacaine followed 90 seconds later by 0.5% ropivacaine in ultrasound guided supraclavicular block provides a quicker onset and a longer duration of analgesia than an equi-dose mixture of the two local anesthetics.

Study Arms (2)
Group 1
ACTIVE COMPARATORcombined group: ropivacaine and mepivacaine mixture: 1:1 volume mixture of 1.5% mepivacaine and 0.5% ropivacaine in 2 syringes (labeled 1 and 2) with 15 mL in each (total, 30 mL) injected in immediate sequence;
Group 2
ACTIVE COMPARATORsequential group: mepivacaine followed by ropivacaine: syringe 1 containing 15 mL of 1.5% mepivacaine, syringe 2 containing 15 mL of 0.5% ropivacaine (total, 30 mL); syringe 2 was injected with a 90-sec delay after injection of syringe 1.
