Upper Extremity Blocks for Hand Surgeons: A Literature Review of Regional Anaesthesia Techniques, Efficacy, and Safety.

Regional anaesthesia (RA) techniques have increased in popularity due to evidence of reductions in acute pain, chronic pain, postoperative nausea and vomiting (PONV), and pulmonary complications. While upper extremity blocks (UEBs) have been the subject of several comprehensive reviews, no review to date has synthesised the information on their use in hand surgery. A search of PUBMED and Cochrane databases was performed to identify the evidence associated with upper extremity blocks.
