Background: Intraoperative neuromonitoring has been introduced to such surgery as head and neck, however, it is insufficient to predict the nerve function. In this study, we evaluate the nerve function by measuring the action potential directory in the operation field. Methods: Sciatic nerves of the rabbits were pulse stimulated electrically. The amplitude of the action potential of the nerve was evaluated on the nerve or surrounding tissue using by a custom-designed bio-amplifier. Results: Two different waveforms of electrotonic spread and the saltatory conduction were recorded. The conduction velocity was 50 to 60 m/s. The amplitude of saltatory conduction on the nerve and surrounding tissue was measured approximately. Discussion: The saltatory conduction in the neighboring tissue was evaluated. It makes possible to detect the action potential derived from the nerve within 10 mm away from the nerve in the operative field.
