Multicenter StudyClinical and technical factors associated with knee radiofrequency ablation outcomes: a multicenter analysis.
There has been a surge in interest in radiofrequency ablation (RFA) of the genicular nerves over the past decade, with wide variability in selection, technique and outcomes. The aim of this study is to determine factors associated with treatment outcome. ⋯ We identified multiple clinical and technical factors associated with treatment outcome, which should be considered when selecting patients for RFA treatment and in the design of clinical trials.

Review Meta AnalysisComparison of postoperative analgesic effects in response to either dexamethasone or dexmedetomidine as local anesthetic adjuvants: a systematic review and meta-analysis of randomized controlled trials.
This review compares the effects of peripheral dexamethasone and dexmedetomidine on postoperative analgesia. We included six randomized controlled trials (354 patients) through a systematic literature search. We found that analgesia duration was comparable between dexamethasone and dexmedetomidine (58.59 min, 95% CI (confidence interval), - 66.13, 183.31 min) with extreme heterogeneity. ⋯ We performed subgroup analyses and found no significant difference between the following: (1) lidocaine vs ropivacaine (P = 0.28), (2) nerve block vs nerve block + general anesthesia (P = 0.47), and (3) upper limb surgery vs thoracoscopic pneumonectomy (P = 0.27). We applied trial sequential analysis to assess the risks of type I and II errors and concluded that the meta-analysis was insufficiently powered to answer the clinical question, and further analysis is needed to establish which adjuvant is better. In conclusion, we believe that existing research indicates that dexamethasone and dexmedetomidine have equivalent analgesic effects in peripheral nerve blocks.

Randomized Controlled Trial
Ultrasound-guided anterior iliopsoas muscle space block versus posterior lumbar plexus block in hip surgery in the elderly: A randomised controlled trial.
Ultrasound-guided posterior lumbar plexus block is widely used for hip fracture surgery but it requires a change of position, which may be painful. ⋯ The anterior iliopsoas muscle space block had the same effect as the posterior lumbar plexus block on peri-operative analgesia for hip surgery, but with a longer onset time. Therefore, anterior iliopsoas muscle space block can be recommended as a routine technique for hip and lower limb procedures.

Diagnostic block and radiofrequency ablation of the acromial branches of the lateral pectoral and suprascapular nerves for shoulder pain: a 3D cadaveric study.
Acromial branches of the lateral pectoral and suprascapular nerves have been proposed as targets for diagnostic block and radiofrequency ablation to treat superior shoulder pain; however, the nerve capture rates of these procedures have not been investigated. The objectives of this study were to use dissection and 3D modeling technology to determine the course of these acromial branches, relative to anatomical landmarks, and to evaluate nerve capture rates using ultrasound-guided dye injection and lesion simulation. ⋯ This study supports the anatomical feasibility of ultrasound-guided targeting of the acromial branches of lateral pectoral and suprascapular nerves. Further clinical investigation is required.

Randomized Controlled Trial
Regional anaesthesia on the finger: Traditional dorsal digital nerve block versus subcutaneous volar nerve block, a randomized controlled trial.
To identify the most comfortable digital nerve block by comparing painfulness and efficiency of two commonly used digital nerve blocks: the volar subcutaneous nerve block and the traditional dorsal nerve block. ⋯ In patients requiring digital anaesthesia in the Emergency Department, the anaesthetic technique affects both the discomfort of the injection and extent of anaesthesia. The traditional dorsal digital nerve block is preferred for dorsal injuries. The subcutaneous volar nerve block is preferred for volar injuries.
