肌电图诱发电位仪对骨折内固定手术中神经损伤的监测
Application of electromyographic in monitoring nerve root at fracture fixation process
摘要
Abstract
Objective To evaluate the noninferiority of domestic electomyographic (EMG) evoked potential instrument utility on avoiding iatrogenic injury of nerve roots compare to the imported ones,and understand the methods,accuracy and practicability of domestic machine on monitoring nerve root at the fracture fixation process.Methods Domestic of Neurocare-C machine and Nicolet Viking select8 concurrent monitoring 30 cases of bone fracture fixation,including 20 cases of spinal fixation and 10 cases of fractures fixation of limbs and pelvic.The trend of positive change,the rate and amplitude variation of electromyographic response between two instruments were compared.Results The nerve root function could be accurately judged by EMG monitoring during operation.Intraoperative EMG could be detected by both domestic and imported instruments occurred in 5 patients,3 cases were internal fixation of vertebral fracture,1 case was humeral fractures fixation,1 case was pelvic fracture.The rate of electromyographic response of both domestic and imported instruments were 16.67％.There was no significant difference in amplitude variation of electromyographic response of quadriceps femoris,biceps femoris,rectus femoris and tibialis anterior between two instruments (P ＞ 0.05).Conclusion Both domestic and imported EMG evoked potentials can accurately and timely respond to nerve root function,avoid nerve root injury,and ensure the safety of fracture fixation surgery.关键词
