Brief Summary
The primary objective of this prospective, descriptive study is to evaluate the success rate of the retroclavicular brachial plexus block and catheter placement in 60 adult patients undergoing hand, wrist, or forearm surgery. The investigators will also evaluate any difficulties performing the procedure, the onset time and distribution of the block, incidence of adverse events, and patient's acceptance of the block.

Outcome Measures
Primary Outcomes (1)
Success Rate
Success rate will be defined as the number of patients with anesthesia or analgesia in all five nerves below the elbow (median, ulnar, radial, musculocutaneous, median nerve of the forearm).
20 minutes after nerve block completed
Secondary Outcomes (3)
Motor Function
20 minutes after nerve block completed
Complication of Procedure
From nerve block completion to patient's arrival in PACU, with an expected average duration of 3 hours
Followup of Block Resolution
48-96 hours post Retroclavicular Brachial Plexus Block
Study Arms (1)
Retroclavicular Brachial Plexus Block
EXPERIMENTALInterventions
A Sonosite ultrasound machine will be used to visualize the nerve and needle simultaneously. A Braun 18 g 4 inch Touhy needle with markings will be inserted into the skin and advanced toward the nerve. Once the optimal location is determined under ultrasound visualization, the local anesthetic, mepivacaine, will be injected beside the nerves. The dose of drug will be mepivacaine 1.5%, 0.5 cc/kg (with a minimum 30 cc and maximum of 50 cc.) A Braun 20 g closed tip polyamide catheter will be inserted next to the nerve and left in place to allow for additional medication to be given postoperatively.
