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
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether combining two sedatives, remimazolam and propofol, works better than propofol alone or with midazolam during a procedure called drug-induced sleep endoscopy (DISE) for people with obstructive sleep apnea. The goal is to see if the combo leads to more successful sedation with fewer side effects. About 174 adults with sleep apnea will take part.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Remimazolam and Propofol
What this could lead to
If successful, this could identify a safer, more effective sedation method for diagnosing sleep apnea, improving patient comfort and procedure success.
What could go wrong
This is a small, single-center phase 4 trial focused on sedation during a diagnostic procedure, not a treatment for sleep apnea itself. Results may not apply to other settings or populations.

Inclusion Criteria: * Patients diagnosed with sleep apnea hypopnea syndrome were included Exclusion Criteria: * Patients were excluded if they had nasal obstruction, significantly deviated nasal septum, nasal turbinate hypertrophy, or nasal polyps. Patients with uncontrolled heart failure, renal insufficiency, diabetes, or hyperthyroidism were also excluded. Patients were also excluded if taking medications that could affect upper airway muscle function, such as ben- zodiazepines and muscle relaxants.
