Remimazolam and Scoliosis Orthopedics
A study testing Remimazolam and Propofol in people with Benzodiazepines, run by Beijing Chao Yang Hospital.
Trial 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. Read more about this study

About this study
Official title: Efficacy and Safety Evaluation of Injectable Remimazolam for Intraoperative Arousal in Scoliosis Orthopedics
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
RemimazolamDrug
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.
PropofolDrug
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.
| Study group | Role | What they receive |
|---|---|---|
| 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. Receives: 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. Receives: Drug: Propofol |
What is being measured
The primary outcome is the main question the study is designed to answer.
Mean time to arousal
the time between the cessation of intraoperative drug infusion and the subject's ability to move the toes on command.
Measured: Perioperative period
Secondary outcomes (5)
Quality of arousal
Class I: the patient wakes up when called, is quiet and moves the limbs as instructed; Class II, the patient wakes up suddenly, moves the limbs involuntarily, does not endanger the internal fixation and tracheal tube, and can move the limbs as instructed; Class III, the patient wakes up suddenly, moves the trunk violently and requires pressure to not endanger the internal fixation and tracheal tube
Measured: Perioperative period
Proportion of successful induction of anesthesia
The criteria for successful induction of anesthesia were that both of the following two requirements were met: completion of tracheal intubation; and no use of remedial sedative drugs
Measured: Perioperative period
Mean time from initiation of dosing to MOAA/S score ≤1
Mean time from initiation of dosing to MOAA/S score ≤1
Measured: Perioperative period
Mean time from discontinuation at the end of surgery to full awakening of the subject
time to the first of three consecutive MOAA/S scores of 5
Measured: Perioperative period
EEG characteristics during the induction, maintenance and awakening periods
EEG power in alpha band, beta band, theta band, and gamma band
Measured: Perioperative period
