Forearm blocks (FAB) are implemented to provide anaesthesia for hand surgeries, as a rescue block for failed or patchy proximal brachial plexus block and to provide postoperative analgesia after a regional or a general anaesthetic [1]. The advantage of these distal blocks is preservation of proximal motor function and avoidance of central structures such as the pleura, subclavian or axillary artery and the phrenic nerve. The proximal muscle function is preserved with these blocks, requiring minimal doses of local anaesthetic. These blocks can be implemented in outpatients [2] and with patients on anticoagulants [3]. Distal nerve blocks do not prevent tourniquet pain since the lateral antebrachial cutaneous nerve of forearm (musculocutaneous nerve), the medial cutaneous nerve of the arm, the posterior cutaneous nerve of the arm, and the intercostobrachial nerve that provide cutaneous innervation of the upper arm are not blocked [4]. The above mentioned nerves are blocked in the arm. Blockade of multiple nerves are needed and so involves multiple injections that may cause more patient discomfort.
