Intraoperative hypotension (IOH) may render patients at a risk of cerebral hypoperfusion with decreasing cerebral blood flow (CBF), and lead to postoperative neurological injury. On the basis of the literature in recent years, this review attempts to refine the definition of IOH and evaluate its impact on neurological outcomes. ⋯ Despite the lack of a known threshold value, IOH is a modifiable risk factor targeted to improve neurological outcomes. Ideal BP management is recommended in order to maintain target BP based on the monitoring of rScO2 or cerebral pressure autoregulation.

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.

ReviewWrong-site nerve blocks: evidence-review and prevention strategies.
There has been increasing attention to wrong site medical procedures over the last 20 years. This review aims to provide a summary of the current understanding and recommendations for the prevention of wrong-site nerve blocks (WSNB). ⋯ Though the evidence is limited, it is recommended that a combination of multiple strategies should be employed to prevent WSNB. These include the use of preprocedural markings, well constructed checklists, time-out/stop-moments, and cognitive/physical aids. Effective implementation requires team education and engagement that empowers all team members to speak up as part of a culture of safety.
