近年许多学者以叠加平均法对使用利多卡因治疗耳鸣的效果进行了电生理学研究。结果一致认为利多卡因对耳鸣有一定疗效。但对作用机制的分析,有的认为有抑制听路神经元的异常兴奋作用,有人则持中枢麻醉学说或作用部位学说等。Robin使用放射性利多卡因静脉注射后,发现药物多集中于神经、皮肤、肌肉且以神经处为最多。Erglessin用~(14)C标记的利多
In recent years, many scholars use the additive averaging method to study the effect of lidocaine on tinnitus using electrophysiological studies. The results agreed that lidocaine has a certain effect on tinnitus. However, the analysis of the mechanism of action, and some think there is an abnormal excitement of the inhibitory pathway neurons, while others hold the theory of central anesthesia or role of part of the doctrine. Robin radioactive lidocaine intravenous injection, found that drugs are more concentrated in nerves, skin, muscles and nerve at the most. Erglessin with ~ (14) C labeled Lido
