ReviewCurrent understanding of the fascial plane blocks for analgesia of the chest wall: techniques and indications update for 2020.
Thoracic myofascial plane blocks have gained popularity because of their ease of performance and relative safety. This review highlights current research demonstrating the efficacy of these blocks for specific surgical procedures and provides a brief description of how these techniques are performed. ⋯ Thoracic fascial plane blocks provide the anesthesiologist a number of techniques to address postsurgical pain. The relative ease of performance and safety profile of these blocks make them an appealing option for pain control for many patients undergoing thoracic or chest wall surgery. Further research is needed to not only define additional indications for each of these blocks, but also explore optimal dosing including the use of continuous catheter techniques.

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.

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.

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.
