在过去的十年中，体感诱发电位（SEP）越来越多地用于术中监测脊髓功能。尽管并发症可能并不常见，但早期识别脊髓功能障碍可以立即采取适当的措施，从而防止不可逆的脊髓损伤。手术期间的脊髓损伤通常是由于压迫或分心造成的缺血和/或机械损伤的结果。监测到的人类 SEP 被认为主要由背柱介导（Halliday 和 Wakefield，1962；Giblin，1964；Larson 等，1966；Cusick 等，1978）。因此，在保留背柱且不改变 SEP 的情况下，可能会发生对其他重要通路（皮质脊髓束）的损伤。因此，了解 SEP 在多大程度上反映手术期间脊髓损伤后未监测的下行运动束功能的变化非常重要。
Over the past decade, somatosensory evoked potentials (SEPs) have been used increasingly for intraoperative monitoring of spinal cord function. Although complications may be uncommon, early recognition of spinal cord dysfunction may allow appropriate measures to be instituted immediately and thus prevent irreversible spinal cord damage. The spinal cord damage during surgery is usually the result ofischemia and/or mechanical injury from compression or distraction. The monitored SEPs in man are thought to be mediated primarily by the dorsal col-umns (Halliday and Wakefield, 1962; Giblin, 1964; Larson et al., l966; Cusick et al., 1978). Consequently, injury to other important pathways (corticospinal tracts) could occur with preservation of the dorsal columns and without a change in the SEPs. Thus, it is important to know to what extent SEPs reflect changes in the function of the unmonitored descending motor tracts following an insult to the spinal cord during surgery.
