Adjuncts to local anaesthetics for the peripheral nerve blocks such as epinephrine, clonidine and opioids have been widely used to enhance quality, duration of anaesthesia and postoperative analgesia. Clonidine, an α2-adrenergic agonist, when combined with local anaesthetics in axillary brachial plexus block has shown to decrease block onset time and prolong the duration of anaesthesia.
