ReviewRegional versus general anesthesia for ambulatory total hip and knee arthroplasty.
With the removal of both total knee and total hip arthroplasty from the Centers for Medicare and Medicaid Services' inpatient-only list, efforts to improve efficiency of the perioperative management of total joint patients have increased recently. The publication of several recent studies examining the impact of anesthesia type on outcomes has prompted the need to review the overall state of evidence for spinal versus general anesthesia for outpatient total joint arthroplasty. ⋯ The type of anesthesia used for total joint arthroplasty may have an important effect on outcomes. Until randomized control trials are performed we must rely on existing evidence, which suggests that both spinal and general anesthesia can lead to successful outcomes after ambulatory total joint arthroplasty.

Observational StudyKetamine Associated Intraoperative Electroencephalographic Signatures of Elderly Patients With and Without Preoperative Cognitive Impairment.
Ketamine is typically used by anesthesiologists as an adjunct for general anesthesia and as a nonopioid analgesic. It has been explored for prevention of postoperative delirium, although results have been contradictory. In this study, we investigated the association of ketamine with postoperative delirium and specific encephalographic signatures. Furthermore, we examined these associations in the context of baseline neurocognition as measured by a validated assessment. ⋯ Ketamine-related changes in EEG are observed in a heterogeneous group of patients receiving spine surgery. This result was driven primarily by the effect of ketamine on cognitively normal patients and not observed in patients that were cognitively impaired at baseline. Furthermore, patients who were cognitively impaired at baseline and who had received ketamine were more likely to develop postoperative delirium, suggesting that cognitive vulnerability might be predicted by the lack of a neurophysiologic response to ketamine.

ReviewRegional anesthesia global health collaborations- a scoping review of current intervention methods.
Perioperative anesthesia-related mortality is significantly higher in low-resource compared to high-resource countries. Regional anesthesia techniques can provide safety, cost, and access benefits when compared to general anesthesia in these settings but is underutilized primarily due to a lack of experienced educators and training opportunities. Academic institutions and international organizations are attempting to fill this educational gap through collaborations, but these efforts need examination for best practices going forward. ⋯ Robust reports on international collaborations providing capacity enhancing educational interventions in regional anesthesia have increased in recent years but are still rare and should be encouraged going forward. Short courses supported by high-resource countries can be effective in low-resource areas when partnerships produce curricula that are well designed.

General Anesthesia in a Patient With Neuronal Intranuclear Inclusion Disease: A Case Report.
Neuronal intranuclear inclusion disease (NIID) is a progressive neurodegenerative disease with diverse clinical manifestations, including dementia and muscle weakness. We summarize anesthetic considerations in reporting general anesthesia for a 58-year-old man with bladder dysfunction and cerebellar ataxia who was diagnosed with NIID. ⋯ The responsiveness to anesthetics may vary widely from case t case. As the number of NIID cases increases, a better understanding of NIID is needed.
