【 摘 要 】

Ultrasound guided nerve block is now becoming the standard practice in regional anaesthesia and hasbeen shown to require less volume of local anaesthetic and reduce the incidence of complications.Median, ulnar and radial nerves are the main peripheral branches of the brachial plexus. Selective blockingof these nerves allows targeted approach and retention of motor power in postoperative period. Thenerves can be blocked at multiple levels in upper limb. This articles describes the indications, relevantsonoanatomy and techniques to perform the blocks and recent advances.
