【Abstract】 Objective To improve the treatment outcome of causalgia by means of indwelling epineurial catheter delivery of analgesics after neurolysis. Methods 12 cases of causalgia after peripheral nerve injury were involved in this study. After interfascicular neurolysis, one end of the epidural catheter was placed under the incised epineurium with its open foramen facing the nerve fascicles proximal to the lesion segment. The other end was fastened to the skin and connected with a syringe. Postoperatively, 2～3 ml (0.5 g/L) bupivacaine was delivered through the catheter every four to six hours. Results Of the 11 cases which were followed for 6 months to 2 years, none had recurrence of the symptoms. One case lost follow up. Conclusions This method is effective for treatment of causalgia. The indication and long term result are subject to further investigation.更多还原
