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.

ReviewAdjuncts to local anesthetic wound infiltration for postoperative analgesia: a systematic review.
Local anesthetics (LAs) are commonly infiltrated into surgical wounds for postsurgical analgesia. While many adjuncts to LA agents have been studied, it is unclear which adjuncts are most effective for co-infiltration to improve and prolong analgesia. We performed a systematic review on adjuncts (excluding epinephrine) to local infiltrative anesthesia to determine their analgesic efficacy and opioid-sparing properties. ⋯ Our findings suggest benefits of several adjuncts to local infiltrative anesthesia for postoperative analgesia. Further well-powered RCTs are needed to compare various infiltration regimens and agents.

ReviewClinical and economic strategies in outpatient medical care during the COVID-19 pandemic.
The COVID-19 pandemic has resulted in significant clinical and economic consequences for medical practices of all specialties across the nation. Although the clinical implications are of the utmost importance, the economic consequences have also been serious and resulted in substantial damage to the US healthcare system, including pain practices. Outpatient pain practices have had to significantly change their clinical care pathways, including the incorporation of telemedicine. ⋯ This review article will provide insight into solutions to mitigate the clinical and economic challenges induced by COVID-19. Undoubtedly, the COVID-19 pandemic will have short-term and long-term implications for all medical practices and facilities. In order to survive, medical practices will need dynamic, operational, and creative strategic plans to mitigate the disruption in medical care and pathways for successful reintegration of clinical and surgical practice.

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.

Randomized Controlled TrialUltrasonographic needle tip tracking for in-plane infraclavicular brachialis plexus blocks: a randomized controlled volunteer study.
Onvision is a new technology for needle tip detection and tracking in ultrasound-guided regional anesthesia. The system consists of a piezoelectric sensor close to the needle tip and an electronic console integrated in the ultrasound system. The needle tip is visualized by a green circle on the ultrasound screen. The aim of the study was to investigate the effect of the new needle tip tracking technology on in-plane infraclavicular plexus blocks. ⋯ Our study on needle tip tracking for infraclavicular blocks did not reveal any significant differences between active needle tip tracking and the control procedures, neither for primary outcome nor secondary outcome measurements.
