在手术矫正脊柱畸形时,脊髓可能发生严重损害,其恢复与内固定能否尽早去除成正比。手术中躯体感觉诱发电位的测定可提供一个早期的警报系统。对病人既安全又无不适。其主要原理是触觉感受器或传入纤维受刺激后,在脊髓和大脑引起电活动变化,显示出电位差,且能连续绘测其波形,由此获得中枢神经系统 In the surgical correction of spinal deformity, the spinal cord may be severely damaged, its recovery and internal fixation can be removed as soon as possible. Surgical somatosensory evoked potentials can provide an early warning system. The patient is safe and no discomfort. The main principle is that the tactile receptors or afferent fibers are stimulated, causing changes in electrical activity in the spinal cord and brain, showing a potential difference, and continuous mapping of its waveform, thereby obtaining the central nervous system
