CommentBuprenorphine management: a conundrum for the anesthesiologist and beyond - a one-act play.
We have witnessed a worldwide upsurge of streamlined enhanced recovery after surgery (ERAS) pathways advocating for consistency and compliance within their guidelines. At a recent national conference, two experts defended their institutional policies on perioperative management of buprenorphine, one defending its continuation, while the other suggesting its discontinuation. ⋯ Although the moderator made a valid statement, we demonstrate via our one-act play the importance of recognizing a subset of the population within an ERAS pathway that necessitates multidisciplinary discussion, communication, and patient-centric care to formulate a perioperative plan coordinating a patient's care. More robust research is needed to minimize variability in current practices and to further develop comprehensive evidence-based guidelines that encompass risk factors and anticipated postsurgical and peripartum pain for patients on buprenorphine.

ReviewAnatomy of the brachial plexus and its implications for daily clinical practice: regional anesthesia is applied anatomy.
Safety and effectiveness are mandatory requirements for any technique of regional anesthesia and can only be met by clinicians who appropriately understand all relevant anatomical details. Anatomical texts written for anesthetists may oversimplify the facts, presumably in an effort to reconcile extreme complexity with a need to educate as many users as possible. When it comes to techniques as common as upper-extremity blocks, the need for customized anatomical literature is even greater, particularly because the complex anatomy of the brachial plexus has never been described for anesthetists with a focus placed on regional anesthesia. ⋯ They describe the anatomy of the brachial plexus (ventral rami, trunks, divisions, cords, and nerves) in relation to the topographical regions used for access (interscalene gap, posterior triangle of the neck, infraclavicular fossa, and axillary fossa) and discuss the (interscalene, supraclavicular, infraclavicular, and axillary) block procedures associated with these access regions. They indicate allowances to be made for anatomical variations and the topography of fascial anatomy, give recommendations for ultrasound imaging and needle guidance, and explain the risks of excessive volumes and misdirected spreading of local anesthetics in various anatomical contexts. It is hoped that clinicians will find this article to be a useful reference for decision-making, enabling them to select the most appropriate regional anesthetic technique in any given situation, and to correctly judge the risks involved, whenever they prepare patients for a specific upper-limb surgical procedure.
