Hoarseness of Voice Following Left Supraclavicular Brachial Plexus Block: A Case Report

Supraclavicular brachial plexus block is extensively used for primary regional anaesthesia as well as postoperative analgesia for the surgical procedures of the upper limb. The evidence for the use of ultrasound in supraclavicular brachial plexus is growing day by day as it has the advantage of allowing real time visualisation of the plexus, pleura and vessels along with the needle and local anaesthetics spread. Despite this, complications can even arise with ultrasound guided supraclavicular brachial plexus block. Hoarseness of voice due to recurrent laryngeal nerve block is a rare complication of supraclavicular brachial plexus block. There are few reported cases of hoarseness of voice following the right supraclavicular block. There is only one reported case of hoarseness of voice following the left supraclavicular block. Here, we report a case of a 16-year-old boy who developed hoarseness of voice due to left recurrent laryngeal nerve following ultrasound guided left supraclavicular brachial plexus block.
