[Brachial plexus. Anesthesia and analgesia]

This review explains the different approaches to the brachial plexus (posterior cervical, interscalene, supra- and infraclavicular, and axillary) and their advantages and disadvantages (indications, contraindications, and complications) for surgery and postoperative or chronic pain management. One of the focussed areas of this review is the use of continuous catheter techniques. Information about the most commonly used local anesthetics as well as adjuncts suggested in the literature is summarized. As essential components for the success of those techniques, organizational and documentation requirements are described. In summary, regional techniques for single shot or continuous block of the brachial plexus are an efficient and safe way of providing anesthesia and analgesia for surgery or pain in the region of the shoulder, arm, or hand.
