Ketamine has been used for decades for a variety of indications. Beyond the historical benefits and effects of ketamine, newer developments have occurred worthy of an update. This review will discuss common uses and indications for ketamine in the perioperative setting, as well as highlight newer indications in recent years. ⋯ Ketamine is regaining popularity in the field of anesthesia and beyond. New studies provide insight on the many indications and use that anesthesia providers may encounter during their perioperative care of patients. Ongoing research is needed to further elucidate ketamine's effects on the management of psychiatric conditions and potential indications for ketamine metabolites.

ReviewInterventions to improve perioperative neurologic outcomes.
Few outcomes in surgery are as important to patients as that of their neurologic status. The purpose of this review is to discuss and categorize the most common perioperative neurologic complications. We will also discuss strategies to help prevent and mitigate these complications for our patients. ⋯ A thorough understanding of threats to patients' neurologic well-being is essential to excellent clinical practice.

ReviewDiaphragm-sparing brachial plexus blocks: a focused review of current evidence and their role during the COVID-19 pandemic.
Given that COVID-19 can severely impair lung function, regional anesthesia techniques avoiding phrenic nerve paralysis are relevant in the anesthetic management of suspected/confirmed COVID-19 patients requiring shoulder and clavicle surgical procedures. The objective of this review is to provide an overview of recently published studies examining ultrasound-guided diaphragm-sparing regional anesthesia techniques for the brachial plexus (BP) to favor their preferent use in patients at risk of respiratory function compromise. ⋯ Existing diaphragm-sparing brachial plexus regional anesthesia techniques used for shoulder and clavicle surgery may help minimize pulmonary complications by preserving lung function, especially in patients prone to respiratory compromise. Used as an anesthetic technique, they can reduce the risk of exposure of healthcare teams to aerosol-generating medical procedures (AGMPs), albeit posing an increased risk for hemi-diaphragmatic paralysis. Reducing the incidence of phrenic nerve involvement and obtaining opioid-sparing analgesia without jeopardizing efficacy should be prioritized goals of regional anesthesia practice during the COVID-19 pandemic.

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.
