Ultrasound-guided peripheral nerve blocks of the upper limb

摘要

Compared with systemic analgesia, regional anaesthesia provides improved postoperative analgesia, reduced pain intensity, less postoperative nausea and vomiting (PONV), and increased patient satisfaction.1 The introduction of ultrasound guidance has been a marked advance in the practice of regional anaesthesia. This article will focus on ultrasound-guided (USG) peripheral nerve blocks (PNBs) of the upper limb.
