- Abstract: 【Objective】 To explore the application of multi-mode electrophysiological monitoring technology in cervical spine surgery. 【Methods】 We retrospectively collected data of patients who received cervical spine surgery in Department of Neurosurgery of our hospital in January 2018 to December 2019. All patients were guided by the bispectral index (BIS) to control the depth of anesthesia. High cervical spine lesions were treated with somatosensory evoked potentials (SEP), motor evoked potentials (MEP), brainstem auditory evoked potentials(BAEP)and electromyography (EMG) monitoring. We selected SEP, MEP and EMG combined monitoring for low cervical nerve and spinal cord injury, recorded and summarized the abnormalities of intraoperative electrophysiological monitoring, surgical efficacy and complications at the time of discharge and 6 months after surgery. 【Results】 The intraoperative BIS parameters of 112 patients were 45-60, the MEP amplitude decreased in 9 cases (8.0%), the SEP amplitude decreased in 4 cases (3.6%), the EMG amplitude was abnormal in 5 cases (4.5%), and the BAEP amplitude decreased in 4 cases (3.6%); no operation was terminated due to significant abnormalities in monitoring. Compared with 44 cases (39.3%) before operation, 112 patients had little change in SEP and MEP amplitudes, 35 cases (31.3%) had a slight increase in SEP amplitude, 2 cases (1.8%) had a slight decrease, 24 cases (21.4%) had slightly increased MEP amplitude, while 7 cases (6.3%) had slightly decreased one. There were no new neurological disorders at the time of postoperative discharge and 6 months after surgery. 【Conclusion】 Multi-mode electrophysiological monitoring shows the recovery of damaged nerve electrophysiological activity immediately after the operation, which provides an objective basis for the recovery of nerve function, and can effectively prevent and reduce iatrogenic spinal cord and nerve function damage, and improve the efficacy of surgery.
