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 This study
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 Results may not be published yet.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

Summary

This study looks at how three common anesthetics—propofol, sevoflurane, and ciprofol—affect the immune system in 80 healthy adults aged 20-30. Participants are randomly assigned to receive one anesthetic or no anesthesia (control group). Blood samples are taken before, during, and after anesthesia to analyze immune cell changes using advanced single-cell technology. The goal is to understand anesthesia's standalone effects on immunity, separate from surgery.

What this could mean

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

Active substance
anesthetic agents (propofol, sevoflurane, ciprofol)
What this could lead to
If successful, this could reveal how common anesthetics influence the immune system, potentially guiding safer anesthesia choices in future medical procedures.
What could go wrong
This is an early-stage observational study in healthy volunteers, not patients. Results may not apply to people with illnesses or those undergoing surgery, and the findings are exploratory.

Study facts

What this study's own registry entry says, in plain language.

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 80 people

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

Started

Nov 2025

Expected to finish

Aug 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Show the full entry requirements

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