Ultrasound-guided Sciatic Nerve Block Puncture Needle

Sciatic nerve block is a commonly used analgesic and surgical anesthesia method in clinical anesthesia department. In addition to nerve blocks that are done clinically with a neurostimulator or empirically, there are sciatic nerve blocks that are ultrasound-guided. Determine the depth of the sciatic nerve and the location of the nerve under ultrasonic positioning, so as to guide the anesthesiologist into the needle, so that the depth and direction of the needle have a more intuitive impression, more reliable than the above two methods, with the patient's signs and symptoms changes, can accurately and quickly complete the nerve block, the block effect is more reliable, relatively rapid, and less side effects.
