Ultrasound-guided Nerve Block Anesthesia Needle

Ultrasound-guided nerve block is a new and visual block technique after the traditional nerve block assisted by color ultrasound. The traditional method adopts blind beating operation, during which the patient should actively cooperate and inform the doctor at any time of the abnormal sensation when the puncture touches the nerve, so that the operating doctor can make adjustments. Conventional blocks require years of experience in anesthesia, and even then the rate of puncture failure and local anesthetic intoxication is still high. The ultrasus-guided nerve block can make the nerve hidden in the subcutaneous or muscle space image on the color Doppler screen, clearly display the nerve course and the relationship between the nerve and the surrounding tissue, improve the success rate of nerve block puncture, shorten the time of block onset, reduce the rate of local anesthetic poisoning, prolong the duration of the block, and greatly improve the safety.
