A simple method of spinal cord monitoring that can be readily used during surgery for spinal disorders in children or adults is described. A spinal subdural recording electrode is placed rostral to the site of surgery and the peroneal nerve is stimulated in the popliteal fossa; in this way, large-amplitude polyphasic spinal somatosensory evoked potentials (SEP's) can be directly recorded. The large amplitude of the spinal SEP's recorded intrathecally facilitates spinal cord monitoring by allowing: 1) rapid acquisition of the evoked response, which provides continuous monitoring during surgery; 2) relatively easy interpretation of the signal, there being no significant ultrashort- or long-latency components to the waveform; and 3) signal acquisition in an electrical environment that would be unacceptable using standard methods of spinal and cortical SEP recording.
本文描述了一种简单的脊髓监测方法，该方法可在儿童或成人脊柱疾病手术过程中轻松使用。将一个脊髓硬膜下记录电极放置在手术部位的头侧，并在腘窝刺激腓总神经；通过这种方式，可以直接记录到大振幅多相脊髓体感诱发电位（SEP）。鞘内记录的脊髓SEP振幅较大，有助于脊髓监测，原因如下：1）能快速获取诱发反应，从而在手术过程中进行持续监测；2）信号相对易于解读，因为波形中不存在明显的超短潜伏期或长潜伏期成分；3）可在使用标准脊髓和皮层SEP记录方法无法接受的电环境中采集信号。
