The radial nerve block may supplement the brachial plexus block. If performing a brachial plexus block at the humeral canal, block the radial nerve before blocking the ulnar nerve. This block can be performed at the humerus, elbow, and wrist levels. Lidocaine, bupivacaine, ropivacaine are the local anesthetics typically used for this procedure.
