- Abstract: 【Objective】 To explore the application of multi-mode electrophysiological monitoring technology in highly selective posterior rhizotomy (SPR) of patients with spastic cerebral palsy. 【Methods】 We retrospectively collected data on patients with systolic cerebral palsy who underwent SPR in our hospital from January 2019 to December 2019. Bispectral index (BIS), somatosensory evoked potentials (SEP) and electromyography during surgery of all the patients were measured. We used EMG to monitor the depth of the anus, spinal cord function, and the stimulation response of multiple muscle groups, and recorded and summarized abnormal intraoperative electrophysiological monitoring, surgical treatment and complications during displacement and discharge, and relief and exercise functional recovery six months after the surgery. 【Results】 The intraoperative BIS parameters of 18 patients were 60-75, the EMG amplitude was abnormal in 1 case (5.6%), and the SEP amplitude decreased in 1 case (5.6%). The preoperative muscle tension of both lower extremities was 3.6 on average, and the postoperative muscle tension was 1.4, with a decrease by 2.2 grades. There were 16 cases (88.9%) in long-term follow-up, among which 12 cases (75%) had complete relief of spasm, 4 cases (25%) had significant improvement, gait function improvement rate was 100%, and no complications occurred. 【Conclusion】 Multi-mode electrophysiological monitoring technology is an effective method for SPR to increase the success rate of surgery. It can increase the accuracy of the ratio of posterior root resection of spinal nerves, reduce the risk of spinal cord damage, and improve the poor prognosis.
