Ultrasound-guided peripheral nerve block is a procedure used in anesthesia that allows real-time imaging of the positions of the targeted nerve, needle, and surrounding vasculature. This improves the ease of performing the procedure, increases the success rate, and may reduce the risk of complications. It may also reduce the amount of local anesthetics requried, while reducing the onset time of blocks.
