在临床针麻实践中,我们采用的切口旁双针(同神经电针)对浅层组织尤其皮肤有较满意的镇痛效应,并总结了最适刺激频率为100HZ,最适刺激强度为最大耐受强度。在应用这种最适刺激参数探讨其镇痛原理的研究中,我们在人体观察到由于切口旁双针的刺激,使针刺部位神经末梢侧一定区域的皮肤出现麻木样针感,以及痛觉降低,触觉与辨别觉迟钝,温度觉基本无变化的感觉分离现象,同时在动物实验中,观察到双针镇痛效应不被影响中枢突触前与突触后两种抑制过程的药物所改变。因此,我们设想切口旁双针
In the practice of clinical acupuncture, we use the paraplegia paraplegia (with the nerve electroacupuncture) on the shallow tissue especially the skin has a more satisfactory analgesic effect and concluded that the optimal stimulation frequency of 100HZ, the optimal stimulus intensity is the largest Withstand strength. In the application of this optimal stimulus parameters to study its analgesic principle, we observed numbness-like acupuncture on the skin of a certain area on the nerve endings side of the acupuncture area due to stimulation by double-needle incision in the human body, and decreased pain relief , The sensation of sensation of touch and discrimination was dull and the sensation of temperature was almost unchanged. At the same time, the analgesic effect of double needle was not changed by the drugs that affect the pre-synaptic and post-synaptic inhibitory processes in animal experiments. Therefore, we envision a double needle next to the incision
