Review Meta AnalysisThe Effects of Perioperative Regional Anesthesia and Analgesia on Cancer Recurrence and Survival After Oncology Surgery: A Systematic Review and Meta-Analysis.
Potentially, perioperative regional anesthesia and analgesia (RA) could influence the outcomes of patients with cancer. The aim of this systematic review and meta-analysis was to evaluate the effects of perioperative RA on survival and cancer recurrence after oncologic surgery. ⋯ Our meta-analysis suggests that RA may improve overall survival but not reduce cancer recurrence after oncologic surgery.

ReviewPathophysiology and Etiology of Nerve Injury Following Peripheral Nerve Blockade.
This review synthesizes anatomical, anesthetic, surgical, and patient factors that may contribute to neurologic complications associated with peripheral nerve blockade. Peripheral nerves have anatomical features unique to a given location that may influence risk of injury. Peripheral nerve blockade-related peripheral nerve injury (PNI) is most severe with intrafascicular injection. ⋯ Distinguishing potential causes of PNI require clinical assessment and investigation; a definitive diagnosis, however, is not always possible. Fortunately, most postoperative neurologic dysfunction appears to resolve with time, and the incidence of serious long-term nerve injury directly attributable to peripheral nerve blockade is relatively uncommon. Nonetheless, despite the use of ultrasound guidance, the risk of block-related PNI remains unchanged.

The Ultrasound-Guided Retroclavicular Block: A Prospective Feasibility Study.
The aim of this feasibility study was to determine the success rate (sensory and surgical) of the novel retroclavicular block and to thoroughly describe the technique. In addition, needle tip and shaft visibility, needling time, procedural discomfort, motor block success rate, patient satisfaction at 48-hour follow-up, and complications were also recorded. ⋯ In this study, the novel retroclavicular block offered a quick, safe, and reliable alternative for distal arm block. Further studies, comparing this approach with the classic infraclavicular block, are required to validate its efficacy, safety, and reliability.

ReviewNeurological Complications Associated With Elective Orthopedic Surgery: Part 2, Common Hip and Knee Procedures.
Many anesthesiologists may not be familiar with the rate of surgical neurological complications of the hip and knee procedures for which they are providing local anesthetic-based anesthesia and/or analgesia. Part 2 of this narrative review series on neurological complications of elective orthopedic surgery describes the mechanisms and likelihood of peripheral nerve injury associated with some of the most common hip and knee procedures, including arthroscopic hip and knee surgery and total hip and knee replacement.
