Clinical trials

Intraoperative neurophysiological monitoring, including motor evoked potentials and somatosensory evoked potentials, is commonly used during spine surgery to help detect impending neurological injury. The quality of these signals can be affected by anesthetic agents. Ciprofol and remimazolam are newer intravenous hypnotic agents that may be suitable for total intravenous anesthesia during procedures requiring neurophysiological monitoring, but direct within-patient comparisons between the two agents are lacking. This single-center, prospective, randomized, two-sequence crossover trial will compare the effects of ciprofol and remimazolam, administered with remifentanil, on intraoperative MEP and SEP signal quality during spine surgery. Eligible participants will be randomized to receive either ciprofol followed by remimazolam or remimazolam followed by ciprofol during predefined stable intraoperative monitoring windows. The primary outcome is the within-participant difference in lower-extremity MEP peak-to-peak amplitude between the ciprofol and remimazolam periods. Secondary outcomes include SEP amplitude and latency, MEP latency, warning-threshold events, hemodynamic variables, rescue medication requirements, recovery characteristics, and postoperative neurological status.

This study intended to investigate the combined Impact of mK-line and mSC-line on the selection of the surgical approach and whether could be used to predict sufficient decompression of cervical spinal cord and clinical outcome in patients after LAMP.

Collect standardized, structured, and comprehensive disease-specific information, produce high-quality and accurate clinical data, provide a sample basis for the analysis and mining of spinal cord injury clinical big data, and establish a spinal cord injury-specific disease data platform to serve clinical work. Promote multi-center cooperation in spinal cord injury research: Establish a unified, standardized, queryable, and sharable efficient spinal cord clinical research data platform to promote multi-center cooperation in spinal cord injury clinical research and enhance the international competitiveness of this research field. Help the region to prepare for the establishment of a spinal cord injury-specific disease data platform for various hospitals in the region, forming a spinal cord injury-specific disease network center to achieve data sharing.
