Transient locked-in syndrome resulting from stellate ganglion block in the treatment of patients with sudden hearing loss

Acta Anaesthesiol Scand. 2003 Apr;47(4):485-7. doi: 10.1034/j.1399-6576.2003.00076.x.


Stellate ganglion blockage (SGB) is a local anesthetic procedure intended to block the lower cervical and upper thoracic sympathetic chain and is one of the treatment modalities for a wide range of disorders such as sudden hearing loss, Menier's disease, stroke, sudden blindness, shoulder/hand syndrome and vascular headache. The complications of SGB are recurrent laryngeal or phrenic nerve block, pneumothorax, unconsciousness, respiratory paralysis, convulsions and sometimes severe arterial hypotension. We present a case with transient locked-in syndrome following SGB for the management of sudden hearing loss. The risk of an intra-arterial injection can be eliminated by rotating the needle, as is described in this report.
