Abstract
- Postherpetic neuralgia is one of the most troublesome disease in pain clinic. Nine patients who suffered from postherpetic neuralgia for 1.5 to 8 month, has been treated with the epidural block for prognostic or therapeutic purpose. Epidural catheter was inserted as close to the involved neural roots as possible, and tip of ep idural catheter was confirmed under fluroscopic guide. Epidural neurolysis was performed out intermittent injection of 1-3 ml of 6% phenol in saline and repeated 2-6 times over one or 7 days interval. Two patients reported satisfactory pain relief and 3 patients reported some pain relief. But 4 patients unchanged after phenol block. The overall duration of pain relief was not studied. Validity and safety of epidural phenol block was not confined. Further study will be necessary before application of epidural phenol block to postherpetic neuralgia.
