皮质体感诱发电位与经颅刺激运动诱发电位技术应用于评价脊柱手术患者脊髓功能的价值比较

Comparative Analysis on the Clinical Value of Cortical Somatosensory Evoked Potential and Transcranial Electrical Stimulation Motor Evoked Potential in the Evaluation of Spinal Function of Patients after Spinal Column Surgery

分析比较皮质体感诱发电位与经颅刺激运动诱发电位在评价脊柱手术患者脊髓功能的临床价值。方法选取2009年3月至2013年2月在江苏省沭阳县人民医院进行脊柱手术的患者236例,同时进行皮质体感诱发电位与经颅刺激运动诱发电位,分别对其检测脊髓神经功能损伤的敏感性和特异性进行观察。结果经颅刺激运动诱发电位的灵敏度为86.20%,特异度为97.97%;皮质体感诱发电位的灵敏度为42.00%,特异度为95.48%,经颅刺激运动诱发电位的灵敏度、特异度均高于皮质体感诱发电位。结论经颅电刺激诱发电位较皮质体感诱发电位能够更为理想地监测脊柱手术中患者的脊髓功能。

Objctive To analyze the clinical value of cortical somatose^sory evoked potential and transcranial electrical stimulation motor evoked potential in the mornitoring of spinal function in spinal column surgery. Methods 236 patients who received spinal column surgery in Shuyang People＇s Hospital from March 2009 to February 2013 were selected for this study. The patients were conducted cortical somatosenso- ry evoked potential and transeranial electrical stimulation motor evoked potential mornitor in the same time, then the sensitivity, specificity of injury of spine were observed. Results The sensitivity, specificity were 86.20% and 97.97% respectively in transcranial electrical stimulation motor evoked potential mornitor;The sensitivity, specificity were 42.00% and 95.48% respectively in cortical somatosensory evoked potential mornitor, which were higher than cortical somatosensory evoked potential mornitor. Conclusion Transcrani- al electrical stimulation motor evoked potential can mornitor the spinal function more effectively than cortical somatosensory evoked potential.
