Case ReportsLong-term brachial plexus anesthesia using a subcutaneous implantable injection system. Case report.
Continuous brachial plexus anesthesia with local anesthesia has been used since 1946 for prolonged surgical procedures, in postoperative pain relief, and in sympathetic nerve block. The benefit or effectiveness of this technique in the relief of sympathetically maintained pain has yet to be established. ⋯ Controlled studies need to be done to establish the safety and efficacy of this form of therapy.

Case ReportsSelective musculocutaneous nerve block and infraclavicular brachial plexus anesthesia. Case report.
Regional anesthesia of the upper extremity may be achieved by the infraclavicular approach to the brachial plexus. ⋯ Stimulation of the musculocutaneous nerve in the infraclavicular region results in biceps muscle contraction. Inadequate anesthesia of the upper extremity may result due to exiting of the musculocutaneous nerve outside the axillary sheath in this region. Evidence of more distal stimulation (finger/wrist flexion) improves the likelihood of successful block of the brachial plexus by the infraclavicular route.
