从我们前项工作说明,选用适宜的电针刺激参数刺激扎管穴可以明显提高腹式输卵管结扎术的镇痛效果。但是,少数受术者仍有镇痛不全的现象。因此,在探讨针麻镇痛原理时,除了考虑筛选更为有效的穴位以及改进电针刺激参数等因素外,同时还应重视受术者的个体差异。目前,国内对针麻镇痛效果的术前预测的研究,已积累了不少宝贵的经验。我们在开展针麻腹式输卵管结扎手术的过程中, From our previous work shows that the use of appropriate electro-acupuncture stimulation parameters to stimulate Zhayin point can significantly improve the analgesic effect of abdominal tubal ligation. However, a small number of patients still have analgesic incomplete phenomenon. Therefore, in the discussion of acupuncture anesthesia principle, in addition to consider screening more effective acupuncture points and to improve the parameters of electro-acupuncture and other factors, but also should pay attention to the subject’s individual differences. At present, the domestic research on the analgesic effect of acupuncture anesthesia has accumulated a lot of valuable experience. We carry out acupuncture anesthesia in the process of tubal ligation,
