Clinical Study of Spinal Cord Evoked Potentials
The author’s experience with ascending SEPs during 36 cases of spinal surgery is reported. Qualified SEP was obtained in 10 of 12 who underwent anterior spinal surgery and in 19 of 24 with posterior spine surgery. In anterior spinal surgery, 4 cases (40%) showed amplitude attenuations more than 30% of baseline amplitude, and in posterior spinal surgery, more than 30% amplitude attenuation was seen in 5 cases (26%) with laminoplasty. There were two cases which showed more than 50% amplitude attenuation; however, postoperative results were not catastrophic (54).
