Cyclopol on Electrophysiological Monitoring During Spine Surgery: a Randomized Controlled, Noninferiority Study

September 12, 2023 updated by: Ruquan Han, Beijing Tiantan Hospital

Effect of Cyclopol on Intraoperative Electrophysiological Monitoring in Spine Surgery: A Randomized Controlled, Noninferiority Study

Postoperative visual function injury occurs after spinal cord, neurosurgery, ophthalmology and other operations, which directly affects the postoperative quality of life of patients. Flash visual evoked potential (FVEP) is important for evaluating visual function under general anesthesia during operation. The changes of visual function can be observed and recognized in time through the amplitude changes of FVEP, which can avoid or reduce the visual function damage during operation. Anesthesia method determines the success and variability of electrophysiological monitoring to a certain extent. The purpose of this study is to investigate the effect of total intravenous anesthesia based on cyclopol on FVEP compared with propofol.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Propofol group
Propofol 1-3mg/kg, sufentanil 0.2-0.4ug/kg and rocuronium 0.6mg/kg will be used for anesthesia induction. The anesthesia maintenance strategy is propofol 4-8mg/kg/h and remifentanil 0.15 - 0.2 μ g/kg/h
Experimental: Cyclopol group
Cyclopol 0.4mg/kg, sufentanil 0.2-0.4ug/kg and rocuronium 0.6mg/kg will be used for anesthesia induction. Anesthesia maintenance strategy is cyclopol 0.8-2.4 mg/kg/h and remifentanil 0.15 - 0.2 μg/kg/h
