自1872年Duchenne首创面神经麻痹的神经兴奋性试验到1964年Hilger刺激器的推广,此试验一直被广泛应用着,但其局限性从未引起大家重视。作者通过六年中130例各种原因所致周围性面神经麻痹患者的分析讨论,提出此试验的局限性及一些改进建议:一、虽然此试验结果被认为是客观反应,但仍受病人主观影响,特别是儿童和精神紧张、痛阈较低的患者。试验时应用镇静剂或浅度全麻并不影响结果。改用球形电极并不断用水湿润可降低刺激极和皮肤间阻力而减轻刺激引起的疼痛。二、仪器问题:如接触不良或电池、电流量不足均会影响结果,建议采用标准的Hilger刺激器及附以电池电流量指示表改进之。三、某些病人显示假阴性反应,即尽管神经已发生变性,但神经兴奋性试验反应仍正常,建议用
Since 1872, Duchenne’s first facial nerve palsy nerve excitability test to 1964 Hilger stimulator promotion, this test has been widely used, but its limitations have never been our concern. Through six years in 130 cases of various causes of peripheral facial paralysis in patients with the analysis and discussion, put forward the limitations of this test and some suggestions for improvement: First, although the test results are considered to be objective, but still subjective influence of patients , Especially for children and those with mental stress and lower pain thresholds. Sedation test or application of light anesthesia does not affect the results. Use of spherical electrodes and continuous wetting with water can reduce the stimulation of the resistance between the pole and the skin and reduce irritation caused by pain. Second, the instrument problems: such as poor contact or battery, the lack of current will affect the results, it is recommended to use a standard Hilger stimulator and attached to the battery current indicator table to improve it. Third, some patients showed false-negative reaction, that is, although the nerve has degenerated, but the nerve excitability test response is still normal, it is recommended
