电针在针麻中常用。从神经生理的角度考虑,电针之所以有镇痛作用,是否因为电针直接作用于外周神经干,因而使之发生传导阻滞?这是一个值得注意的问题。本实验以蟾蜍的外周神经作为对象,以矩形波(简称方波)所引起的神经复合动作电位作为指标,观察了电针刺激对离体外周神经传导功能的影响。 Electro-acupuncture anesthesia commonly used. From the neurophysiological point of view, the reason why electroacupuncture has analgesic effect is because of the direct effect of electroacupuncture on the peripheral nerve stem, which led to block? This is a noteworthy issue. In the present study, the peripheral nerve of toad was taken as the object, and the nerve complex action potential caused by the rectangular wave (referred to as square wave) was used as an index to observe the influence of electroacupuncture on the peripheral nerve conduction function in vitro.
