To provide an overview of acute and chronic repeated concussion. We address epidemiology, pathophysiology, anesthetic utilization, and provide some broad-based care recommendations. ⋯ Brain physiology may be abnormal following concussion and these abnormalities may persist despite resolutions of clinical manifestations. Those with recent concussion or chronic repeated concussion may be susceptible to secondary injury in the perioperative period. Clinicians should suspect concussion in any patient with recent trauma and strive to maintain cerebral homeostasis in the perianesthetic period.

ReviewHas the future arrived? Liposomal bupivacaine versus perineural catheters and additives for interscalene brachial plexus block.
Single injection interscalene block (ISB) provides effective analgesia for shoulder surgery. However, the duration of these is limited. This review summarizes the effectiveness of three potential means of extending the duration of analgesia: perineural infusion of local anesthetic agents, addition of adjuvant drugs to local anesthetics in single-injection nerve block, and utilization of liposomal bupivacaine in the surgical field or in the block itself. ⋯ Interscalene catheters, adjunctive drugs added to local anesthetics in single-injection interscalene brachial plexus blocks, or liposomal bupivacaine may be used to effectively prolong the duration of analgesia for shoulder surgery patients.

ReviewDouble standards: why is pulse oximetry standard care, whereas tissue oximetry is not?
Why is pulse oximetry a standard monitor, whereas tissue oximeter is not? Is this a double-standard treatment? ⋯ Pulse oximetry and tissue oximetry are treated differently although neither monitor has robust evidence attesting to its outcome benefits. This difference may root in the difference in the physiology they monitor, the cost, the ease of use/interpretation/intervention and the relevance to patient safety and care quality. Pulse oxygen saturation represents a vital sign, whereas tissue oxygen saturation is likely a quality sign; however, further research endeavors are required to fully understand how to best use tissue oximetry.

Prospects of molecular hydrogen in perioperative neuroprotection from basic research to clinical application.
The current systematic review summarizes recent, basic clinical achievements regarding the neuroprotective effects of molecular hydrogen in distinct central nervous system conditions. ⋯ Fundamental and clinical evidence supports the antioxidant, antiinflammation, antiapoptosis and mitochondrial protective effects of hydrogen in the pathophysiology of nervous system diseases. The clinically preventive and therapeutic effects of hydrogen on different neural diseases, however, remain uncertain, and the lack of support by large randomized controlled trials has delayed its clinical application.

ReviewPostoperative delirium: why, what, and how to confront it at your institution.
The current article reviews the importance of postoperative delirium (POD), focusing on the older surgical population, and summarizes the best-practice guidelines about POD prevention and treatment which have been published within the last several years. We also describe our local experience with implementing a perioperative delirium risk stratification and prevention pathway, and review implementation science principles which others may find useful as they move toward risk stratification and prevention in their own institutions. ⋯ POD continues to be a serious perioperative complication commonly experienced by older adults. Growing appreciation of its prognostic implications and evidence behind multidisciplinary, collaborative, and focused prevention strategies rooted in implementation science have prompted several major groups to issue consensus guidelines. Adopting best practices POD risk stratification and prevention pathways will improve perioperative care for older adults.
