Clinical Trial Summary

Brachial plexus blocks (BPB) are commonly used to provide regional anaesthesia for patients undergoing distal radial fracture surgery. Distal radial (DR) fracture surgery is a commonly performed orthopaedic surgery, and is usually associated with moderate postoperative pain. Poor postoperative pain control can impair rehabilitation, delay recovery and negatively impact outcomes after surgery. Liposomal bupivacaine (EXPAREL) is a multivesicular formulation of bupivacaine that allows rapid absorption and prolonged release of bupivacaine. Liposomal bupivacaine can provide longer analgesia for up to 72 hours, and may therefore achieve greater analgesic efficacy compared to non-liposomal long-acting local anaesthetics. A number of clinical trials have studied the effect liposomal bupivacaine given as local infiltration. However, there is little evidence on liposomal bupivacaine for regional nerve blocks, and the use of liposomal bupivacaine for supraclavicular brachial plexus block - which is used for regional anaesthesia for distal radial fracture surgery - have not been studied before. This project is a randomized controlled trial to determine whether adding liposomal bupivacaine to long-acting local anaesthetics for supraclavicular BPB will improve and prolong postoperative analgesia in patients undergoing distal radial fracture surgery. Longer term secondary outcomes would be accessed including upper limb functional scores, chronic pain, and health related quality of life.
