Evaluation Of Clinical Application Of SEP Combined With MEP Monitoring In Patients With Spinal Canal Tumor

Objective: To investigate intranperative the value Evaluation of the somatosensory evoked potential(SEP) combined with motor evoked potentials(MEP) examination in pr eventing spinal canal resection complications and operative prognosis.Methods: Select september 2013- October 2015 of Ningxia Medical University Hospital 50 case spinal canal, six cases of intramedullary tumors(Ependymtoma four cases; strocytoma two case),.Extramedullary tumors 44 cases(20 cases of neurinoma 22 cases of meningioma,2 cases of epidemoid);Intraoperative electrophysiological monitoring 20 cases, No electrophysiological monitoring group of 30 patients; Physical examination include the four limbs muscle strength, muscle tension and activities of the situation, the limbs and trunk feeling. According to the JOA score of their ratings. To carry out the statistical analysis of the preoperative and postoperative spinal cord func tion changes and The relationship between evoked potentials.Preoperative muscle strength and no more than two full stages of sensory loss, abnormal physiological indicators of the presence of preoperative, epilepsy, or skull after skull defect repair or heart disease.Results: The issue under microscope tumor total resection in 47 cases, subtotal earnest in 2 cases, 1 case of severe adhesions between tumor and spinal cord cone, when dissecting the tumor emerging electrophysiological alarm, consider the tumor and normal nerve tissue,separation is very difficult, Directorate downlink partial resection; Stop the operation a few minutes, But do not return to their own baseline level of volatility, symptoms are significantly worse.; after a week JOA scores improved electrophysiology group 10 cases, unchanged in 8 cases, 2cases descends,the control group of 25 people,are improved, 4 cases spinal deterioration, including three cases of severe, JOA score decreased 2 points. Monitoring group postoperative spinal cord function was significantly higher than the overall improvement of the monitoring group, indicating somatosensory evoked potential(SEP) combined with motor evoked potentials(MEP) monitoring.After one week JOA score monitoring group Improved 10 cases, unchanged 8 cases, 2 cases of spina cord function deterioration,Before and after the operation, the latency of SEP-P40(ms) and amplitude(uv), the latency of MEP-APB(ms) was significantly(P<0.05).Conclusion:SEP combined with EMP monitoring in the spinal canal for a resection of the damage caused to the nervous system on the prevention of postoperative...
