Abstract
We report in 3 patients that high-frequency ultrasound 3-dimensional imaging enabled us to analyze anatomic variations, evaluate local anesthetic spread, and optimize a perineural catheter location by withdrawing it until its tip was appropriately positioned. This innovative technology may provide answers to different problems facing the operator performing ultrasound-guided nerve blocks. It may enhance predictability and safety aspects of peripheral nerve blocks.
