摘要

背景:术中神经监测已被引入到头颈部等外科手术中,但尚不足以预测神经功能。在本研究中,我们通过测量术野的动作电位目录来评估神经功能。方法:采用脉冲电刺激家兔坐骨神经。使用特制的生物放大器,在神经或周围组织上评估神经动作电位的振幅。结果:记录了两种不同的电紧张扩散波形和跳跃式传导波形。传导速度为50 ~ 60m /s。近似测量了神经及周围组织的震荡传导幅度。讨论:评价邻近组织的跳传导。可以在手术野范围内检测到距离神经10mm以内的动作电位。

Measurement of the action potential of the nerve for the isolation of the nerve in the operative field: An experimental study in rabbit
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.
