ABSTRACT：ObjectiveTo analyze the dual-channel with single channel recorded somatosensory evoked potentials（SSEPs）monitoring in the thoracic vertebral disease that underwent surgical fixation surgery waveform differentiation and evaluate the value of dual-channel SSEPs applied in thoracic surgery diseases.MethodsThe study included l35 patients who underwent surgery for thoracic vertebra disease in Xi'an Honghui hospital from November 2019 to November 2O23.Of them，66 underwent conventional single-channel SSEPs monitoring and 69 underwent dual-channel SSEPs monitoring.By observing the waveform diferentiation of single-channel SSEPs and dual-channel SSEPs，Chi-square test and Fisher exact test were used to analyze the influences of age and etiological classification on the waveform differentiation and monitoring success rate of SSEPs.The success rate of intraoperative monitoring and the incidence of postoperative adverse events in alarm cases were compared between the two groups.ResultsUnivariate analysis showed that age group and etiological clasification of thoracic vertebral diseases affected the successrateof intraoperative SSEPs monitoring.Among the etiologicalclasification， the SSEPs waveform diferentiation in fracture group was the least ideal.Intraoperative monitoring results showed that the success rate of single-channel SSEPs monitoringwas 80.30% ，while the success rate of dual-channel SSEPS monitoring was 98.55% （ P<0.05） . Inthe intraoperative alarm cases，the incidence of postoperative adverse events monitored by single-channel SSEPs was 66.67% ； the incidence of adverse events after dual-channel SSEPs monitoring was 33.33% . Conclusion The age of patients and etiological type of thoracic spine diseases affect the success rate of intraoperative SSEPs monitoring. Dual-channel SSEPs monitoring can effectively and accurately evaluate the functionof patients with posterior spinal cord conduction pathway.Using dual-channel SSEPsmonitoring can significantly improve the success rate of monitoring and reduce the occurrence of postoperative adverse events in patients with thoracic vertebra disease.
