| Research Abstract |
In the present study, two different treatments for chronic pain of upper extrimities, namely epidural spinal cord stimulation(ESCS)and epidural blook were compared in terms of improvement of subjective symptomes and change of peripheral blood flow. Both parameters were evaluated by visual analogue scale(VAS)and near infrared spectrometry, respsctively. Fifteen patient, including those with postherpetic neuralgia and posttraumatic cervical syndrome were subjected to this study. Under fluoroscopy, multipurpose epidural catheter was inserted into epidural space equivqlent level of the pain. The probe of near infrared spectrometry was put on the muscle with the pain and monitored during and 2hrs after 45 min ESCS following 10 min rest at 25°C.The other day, 6 ml of 1% lidocaine solution was administered through the epidural catheter and same monitoring was performed. VAS was decreased in both treatment, but statistical difference was not noticed before or after the treatments. On the contrary, significant elevation of oxy-Hb and total Hb was observed after ESCS, and they were significantly higher than epidural block. These indicate that ESCS showed analgesic effect independently of peripheral blood flow. Moreover, evaluation of skin temperature, monitored by thermography, was applied in the tow treatments for the patients with postherpetic neuralgia, reflex sympathetic dystropy, lumbar canal stenosis or brachial plexus neuropathy. Analgesic effect of each patient depends on the disease and they are irrelevant to skin temperature. In conclusion, parameters of peripheral blood flow can not be a indicator of analgesic effect between ESCS and epidural block.
