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 epidural 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.

Epidural neurolysis with phenol has appeared in literature since 1960. Complications due to accidental subdural block is a rare and unexpected sensory and/or motor disturbance, but it does occur. A 74 years old woman had postherpectic neuralgia for 3 weeks and VAS score of 10. She was treated with intercostal nerve block and intravenous infusion of lidocaine for 7 days and VAS score decreased to 6. To proceed further, we decided to perform epidural neurolysis with 4% phenol 1.5 ml. During thoracic epidural catherization, we encountered unexpected subdural catheterization in subdurographic finding, but we could not precisely rule out subdural catheterization. We had to check CT for exact location of catheter tip. We then performed subdural neurolysis with phenol. This procedure reduced VAS score to between 3 and 4, and we removed the catheter. She had no complication.

Intraspinal alcohol or phenol administration has been used for the treatment of intractable pain due to terminal cancer. It has been alleged to produce good pain relief with minimal complication if performed carefully. We analysed 35 patients who received epidural or subarachnoid neurolytic block out of 83 patients with malignancy who were referrecl to our pain clinic. Most of the patients needed additional treatment modalities including epidural catheterization or systemic narcotic administration. The incidence of complication was high, especially when the neurolytic agents were administered in the lumbar region. This suggest that intraspinal neurolytic block is unreliable and unsafe, although it may temporarily reduce the analgesic requirement.

제1족지단(第一足趾端)에 심한 통증(痛症)과 궤양(潰瘍)으로 입원한 31세(歲)의 Buerger 병(病) 환자(患者)에 X-선조(線造) 영하(影下)에서 7% phenol을 사용한 제(第)1, 2 및 3 요부교감신경절차단(腰部交感神經節遮斷)을 시행하였다. 교감신경절차단후(交感神經節遮斷後) 족지(足趾)의 통증완화(痛症緩和)와 온감(溫感)을 느낄 수 있었으며 이후 2회(回)의 2.5% bupivacaine을 이용한 경막외강차단(硬膜外腔遮斷) 후 통증(痛症)소실과 함께 순환혈류(循環血流) 개선(改善)을 plethysmogram으로 확인할 수 있어서 성공적인 교감신경절차단술(交感神經節遮術)이 시행됐다고 볼 수 있어 문헌적(文獻的) 고찰(考察)과 함께 보고(報告)하는 바이다.

Transsacral neurolytic block with 2.5ml of phenol in glycerine or bupivacaine was performed in 6 patients with malignant diseases and a patient with sphincter spasm of bladder due to spinal cord injury. Pain relief was satisfactory in all patints except one patient with very low pain threshold. In one patient, second transsacral neurolytic block alone was not sufficient because of widespread pain along distant metastasis of the malignant disease, although the first block was satisfactory. The complications include transient motor weakness(4), voiding difficulty(1), subarachnoid puncture(1), and epidural venous puncture(1), but they were all spontaneously recovered within a sbort period of time and did not give any limitation to the block.
