Identification of spread after deliberated intraneural injection in five mammalian species: not all animal models and needle types are valid for studying the effect of intraneural injections in humans.
This research endeavors to investigate the phenomenon of intraneural spread across distinct locations: subcircumneurium, extrafascicular intraneural, intrafascicular intraneural, and intraperineurium after deliberate intraneural injections across five mammalian species. The study also aims to propose determinants influencing this spread. Furthermore, the investigation strives to ascertain the optimal animal species and needle configuration for extrapolating intraneural injection outcomes to human contexts. ⋯ Despite the formidable challenges associated with the practical realization of intrafascicular injection, the utilization of animal models possessing monofascicular or oligofascicular nerves, such as rats, rabbits, and dogs, in conjunction with needles featuring aperture dimensions surpassing those of the fascicles, likely contributes to the compromised reliability of investigations into intraneural injection outcomes.

Review Meta AnalysisDifferent peripheral nerve blocks for patients undergoing total knee arthroplasty: a network meta-analysis of randomized controlled trials.
To comprehensively compare the effect of different peripheral nerve blocks for patients undergoing total knee arthroplasty (TKA). ⋯ cACB combined with IPACK/GNB may be the most favorable block after TKA, continuous blocks may be better than single-shot blocks, and combined blocks may be better than separate blocks.

Randomized Controlled Trial Comparative Study
Comparison of the Efficacy of Ultrasound-Guided Suprascapular Nerve Blocks and Intraarticular Corticosteroid Injections for Frozen Shoulder: A Randomized Controlled Trial.
The current mainstream treatment for frozen shoulder is a combination of physiotherapy and intraarticular corticosteroid injections (IACIs). Recently, the ultrasound-guided suprascapular nerve block (SSNB) has developed as a notable alternative option to the mainstream treatment. ⋯ A combination of ultrasound-guided IACIs and physiotherapy should be attempted first as a frozen shoulder treatment.
