摘要
目的：研究皮层下体感诱发电位对脊柱侧凸矫正手术监测的准确性，提高术中预防神经损伤的有效性。方法：对４１例脊柱侧凸患者于矫正术中采用皮层下体感诱发电位和皮层体感诱发电位监测脊髓功能。结果：皮层下体感诱发电位波形稳定可靠，很少受麻醉的影响；皮层体感诱发电位受麻醉影响较大，波幅几乎可消失。全组５例皮层下体感诱发电位出现异常，其中２例与临床相符，３例为假阳性；无假阴性发生。准确率为９２７％。结论：应用体感诱发电位术中监测脊髓功能，皮层下体感诱发电位是目前较理想的方法。
Objective: To study the use of subcortical somatosensory evoked potential monitoring in
scoliosis surgery so as to prevent intraoperative neurological complications. Method: 41 cases
with scoliosis underwent corrective operation monitored by somatosensory evoked
potential(SEP) that included both subcortical somatosensory evoked potential(SubCSEP) and
cortical somatosensory evoked potential(CSEP).The critical limits of SubCSEP intraoperative
monitoring were set in advance. Result: Anesthetic agents could affect CSEP prominently but
SubCSEP could hardly vary.5 cases overtook the critical limits and 3 of them were false
positive.There were no false negative and the accuracy of SubCSEP was 927%. Conclusion:
SubCSEP is an ideal method to monitor the spinal cord function in scoliosis surgery
