Abstract：Objective To analyze the changes in the duration and amplitude of somatosensory evoked potential before,during and after surgery,and to evaluate the neurological status of recipients of spinal cord surgery and influencing factors.Methods Fifty recipients of spinal cord surgery admitted to the Third Hospital of Hebei Medical University between June 2017 and December 2017 were selected as the subjects, among whom preoperative,intra-operative and postoperative somatosensory evoked potential examinations were performed and the results were recorded and statistically analyzed.Results The SEP latency of the left lower extremity and the right lower extremity was longer than that of the preoperative period (P<0.05). There was no significant difference between SEP amplitudes of the left lower extremity and the right lower extremity (P>0.05).The SEP latency of the left lower limb and the right lower limb was shorter than before surgery (P<0.05). The SEP amplitude of the left lower limb and the lower right limb was higher than before surgery(P<0.05).Conclusions The monitoring of somatosensory evoked potential before,during and after spinal cord surgery can help to keep track of the neurological function, facilitate surgery and assess postoperative neurological recovery.
