The changes of the trigeminal somatosensory evoked potential (TSEP) before, during and after inferior alveolar nerve block were serially recorded in six healthy subjects (33-43 years of age; mean age 38.0 years). In four subjects in whom successful nerve block was achieved, TSEP showed linear flattening of the wave form. The recovery of TSEP slightly preceded the recovery of threshold of the sensation to electrical stimulation and that of two-point discrimination on the skin. In the remaining two subjects, in whom effective nerve block failed, TSEP showed no change in the wave form but did show slight prolongation of the latencies. We conclude that TSEP can be used as a method to confirm whether conduction anesthesia has been successful or unsuccessful.
在6名健康受试者（年龄33 - 43岁；平均年龄38.0岁）中，连续记录了下牙槽神经阻滞前、阻滞期间及阻滞后的三叉神经体感诱发电位（TSEP）。在4名成功实现神经阻滞的受试者中，TSEP显示波形呈线性平坦化。TSEP的恢复略早于对电刺激感觉阈值和皮肤两点辨别觉阈值的恢复。在其余2名有效神经阻滞失败的受试者中，TSEP波形无变化，但潜伏期略有延长。我们得出结论，TSEP可作为一种方法来确认传导麻醉是否成功。
