What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looks at two ways of using a muscle relaxant drug (rocuronium) during spine surgery. One group gets a low dose throughout surgery, the other stops the drug after the start. The goal is to see which approach gives clearer nerve signals for monitoring the spinal cord. About 62 adults having spine surgery will take part at Bach Mai Hospital in Vietnam.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 62 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Jun 2026

An estimate. Start dates often move.

Expected to finish

Dec 2028

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: \- 1. Patients aged 18 years or older. 2. Patients scheduled for spine surgery under general anesthesia. 3. Patients undergoing spine surgery with intraoperative neurophysiological monitoring, including motor evoked potentials and/or somatosensory evoked potentials. 4\. Patients who agree to participate in the study and provide written informed consent. Exclusion Criteria: * 1\. Pre-existing central or peripheral neurological disease that may affect intraoperative neurophysiological monitoring, such as quadriplegia, persistent sensory disorder, sequelae of stroke, or polyneuropathy. 2\. History of epilepsy or electroencephalographic disorder. 3. Use of neuropsychiatric drugs, strong sedatives, or drugs affecting neuromuscular or neurological conduction within 48 hours before surgery. 4\. Decompensated cardiovascular disease or severe respiratory disease that may affect emergence or anesthetic drug metabolism. 5\. Contraindication to intraoperative neurophysiological monitoring. 6. Contraindication to rocuronium. 7. Refusal to participate or withdrawal of consent at any time..
