以伤害刺激诱导的皮层动作电位能否作为疼痛指标尚有争论。现将皮层动作电位和既定的疼痛指标联合记录,并观察其对镇痛刺激有无一致性反应,从而对此作一评定。本文所用的既定疼痛指标为电击家兔鼻唇部诱导的头后浅直肌动作电位,镇痛刺激为电针和静脉注射50％葡萄糖,这些都是作者等以往工作肯定的。用30~50V,波宽0.5ms,2秒一次方波电击家兔鼻唇部作为伤害刺激,将从皮层眶回和从头后浅直肌诱导的动作电位分別或同时导至ATAC-201迭加仪进行32次平均加算。先单独观察了九例皮层动作电位对电针的反应,结果在用G6805电麻仪输出2V电针“合谷”10
To hurt the stimulation-induced cortical action potential as an index of pain is still controversial. The cortical action potential and the established pain indicators are now jointly recorded and observed whether there is a consistent response to analgesic stimulation to assess this. The established pain index used in this paper is the posterior posterior shallow rectus muscle action potentials induced by electric shock on the nasolabial parts of rabbits and the analgesic stimulation is electroacupuncture and intravenous injection of 50% glucose, all of which are affirmed by the author’s previous work. With 30 ~ 50V, wave width 0.5ms, 2 seconds a square wave electric shock on the nose and mouth of rabbits as a noxious stimulation, the action potential induced from the orbital floor and the posterior posterior shallow rectus muscle separately or simultaneously lead to ATAC-201 superposition The instrument performs 32 average additions. The first nine individual observations of the response of cortical action potentials to electroacupuncture results in the use of G6805 electric marijuana output 2V electroacupuncture “Hegu” 10
