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.

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.

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.

ReviewDaring discourse: are we ready to recommend neuraxial anesthesia and peripheral nerve blocks during the COVID-19 pandemic? A pro-con.
The recent joint statement from the American Society of Regional Anesthesia and Pain Medicine (ASRA) and the European Society of Regional Anesthesia and Pain Therapy (ESRA) recommends neuraxial and peripheral nerve blocks for patients with coronavirus disease 2019 (COVID-2019) illness. The benefits of regional anesthetic and analgesic techniques on patient outcomes and healthcare systems are evident. Regional techniques are now additionally promoted as a mechanism to reduce aerosolizing procedures. ⋯ In this Daring Discourse, we present two opposing perspectives on adopting the ASRA/ESRA recommendation. Areas of controversy in the literature and opportunities for research to address knowledge gaps are highlighted. We hope this will stimulate dialogue and research into the optimal techniques to improve patient outcomes and ensure practitioner safety during the pandemic.

Randomized Controlled TrialComparison of the ultrasound-guided single-injection femoral triangle block versus adductor canal block for analgesia following total knee arthroplasty: a randomized, double-blind trial.
The aim of the study is to compare the femoral triangle (FT) and adductor canal (AC) blocks in terms of the analgesic efficacy and ambulatory outcomes in the context of multimodal analgesia following total knee arthroplasty (TKA). ⋯ The preoperative FT block provided improved analgesic outcomes without compromising functional mobility in the context of multimodal analgesia following TKA compared with the AC block.
