Complex issues in new ultrasound-guided nerve blocks: how to name, where to inject, and how to publish.

The recent development of ultrasound-guide nerve block has led to innovation in anesthesia and pain clinics. However, it has also led to some complex issues, including (1) how to name a new technique, (2) the appropriateness of an intramuscular approach, and (3) how to publicize a new technique. This review addresses naming strategy, feasibility of intramuscular approach block, and methods of publication. First, researchers and authors should pay attention to appropriate nomenclature for the term 'approach', 'compartment block', and 'nerve block' for a new block. Second, it is lack of evidences to facilitate muscle injection, and adequate preparation and adherence to proper technique for intramuscular approach block should be considered; confirmation of abnormal signs at the injection area, use of a thin needle and the lowest concentration and volume of local anesthetic without supplementation with steroid or epinephrine, compressing hemostasis, and sufficient interval of the blocks. Third, adequate dissemination of information would also be necessary through publication in appropriate media. We hope this review boost reasonable development of nerve block.
