Brief Summary

Spinal cord injury is one of the most dangerous complications of scoliosis orthopedic surgery, and the Stagnara awakening test has been used in orthopedic spine surgery and is considered the "gold standard" for detecting spinal cord injury. During the awakening test, the patient is awakened from anesthesia and, in conjunction with a neurological assessment, moves his or her fingers and toes to determine the integrity of spinal cord motor function in order to avoid spinal cord injury. During this procedure, the patient still requires a degree of sedation and analgesia to tolerate tracheal intubation and surgical pain. Remazolam benzoate for injection is a new class of benzodiazepines that are ultra-short-acting sedative/anesthetic drugs. It has the advantages of rapid onset, rapid elimination, and no drug accumulation by continuous infusion, and has the advantage of being applied to wake up during spinal orthopedic surgery, but its effectiveness and safety are still unclear. This study aims to elucidate the safety and efficacy of rimazolam benzoate for injection for arousal in spinal orthopedic surgery through a single-center, randomized, single-blind, positive drug-controlled trial, with the aim of providing a basis for the development of a safe and effective anesthetic protocol for such surgery.

Study Arms (2)

remimazolam group

EXPERIMENTAL

For induction of anesthesia, rimazolam benzoate was pumped at a rate of 12 mg/kg/h; for maintenance of anesthesia, 1.0-2.0 mg/kg/h rimazolam was given as a continuous pump.

Drug: Remimazolam

propoful group

ACTIVE COMPARATOR

For induction of anesthesia, propofol medium-length chain fatty milk injection 2 mg/kg was given by intravenous push; for maintenance of anesthesia, 6-8 mg/kg/h propofol medium-length chain fatty milk injection was given by continuous pumping.

Drug: Propofol

Interventions

During induction of anesthesia, the rimazolam group was given rimazolam pumped at a rate of 12 mg/kg/h During the maintenance phase of anesthesia, the rimazolam group was given 1.0-2.0 mg/kg/h of rimazolam continuously pumped.

remimazolam group

During induction of anesthesia, propofol 2mg/kg was given, and during the maintenance phase of anesthesia, propofol 6-8mg/kg/h was given as a continuous pump.

propoful group
