AbstractA 72-year-old man, 154 cm tall, weighing 53 kg was suffering from severe herpetic neuralgia on his left 10th intercostal nerve area. His pain continued even he was treated with frequent epidural nerve block (4 to 5 times per week) by an anesthesiologist. He was referred to our hospital on his 105th pain day. He complained severe continuous pain and numbness on his left 10th intercostal nerve area. Touching the painful skin induced lightning pain. His pain was so severe that his sleeping was disturbed and also he could not maintain his usual life. Epidural nerve block at 10th thoracic nerve was done with 20mg methylprednisolone acetate and 5ml of 1% lidocaine. After the treatment, his pain was reduced to 3/10 of the one he had on admission, and also his sleep was not disturbed further. Epidural nerve blocks with methylprednisolone weekly for a month induced no more remission. At his 154th pain day, a dose of 20mg methyl prednisolone acetate and 1% lidocaine 5ml was given intrathecally through 2nd lumber intervertebral space. The pain was relieved completely after the block. And he complained nothing about the skin area which had been disturbing his life for a long time. Auditory brainstem response which was recorded during the block showed prolongation of the latency of phase III and phase V at 40 minutes after the intrathecal injection of lidocaine.
