Prepackaged collections of the devices and supplies (i.e., either custom or standard kits) needed for providing local anesthesia to the arm distal to the shoulder. Items in these kits usually include sterile towels, gauze packs, syringes filled with local anesthetics, sterile gloves, marking pen, surface electrodes, a needle for skin infiltration, a three-way stopcock; kits may also include a peripheral nerve stimulator. The kits are frequently supplied in supporting trays (i.e., procedure trays) consisting of a flat-bottomed receptacle with a border around the periphery supporting all the instruments and supplies needed for the procedure; the trays are usually covered or wrapped. Brachial-plexus anesthesia procedure kits and trays are intended for use in the block of axillary brachial plexus roots during diagnostic and/or therapeutic procedures.
