Abstract
Wrist and elbow blocks are used to provide anaesthesia and analgesia for hand and forearm surgery. They may be used to supplement a brachial plexus block or to provide perioperative analgesia after a regional or a general anaesthetic. Wrist or elbow blocks alone may be used to provide anaesthesia for minor hand procedures; thus, sparing the patient the complications of general anaesthesia and providing excellent postoperative analgesia with a reduced requirement for opioid analgesics. Proximal brachial plexus block is associated with more motor block, but will provide partial or complete tourniquet anaesthesia. Therefore, sole reliance on peripheral arm blocks can only be advocated in procedures that do not require a tourniquet or last approximately ,20 min.
