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
Running, but no longer taking on new participants.
Completed This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 trial tests whether a stellate ganglion block—an injection near a nerve cluster in the neck—can help people recover faster after heart valve replacement surgery. Half of the 62 participants receive the block with a numbing medication, while the other half gets a placebo. Researchers track complications like infections, arrhythmias, and kidney issues, as well as hospital stay length and survival at 30 days, to see if the block improves recovery.

What this could mean

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

Active substance
stellate ganglion block with ropivacaine
What this could lead to
If effective, this nerve block could reduce postoperative complications and shorten hospital stays for heart valve replacement patients.
What could go wrong
This is a small, early-stage trial, and results may not apply broadly. Risks include local anesthetic allergy and potential nerve block complications.

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

Inclusion Criteria: \- Sixty patients with cardiac Valve replacement undergoing elective cardiopulmonary bypass, with cardiac function class II-IV and ASAII-IV, aged 18-70 years. Exclusion Criteria: \- Patients with off-pump cardiac Valve replacement, age \> 18 years or \> 70 years, cardiac function ≥ III, ASA grade ≥ III, local anesthetic allergy, concomitant immune disease or immunosuppressive status, patients with severe mental disorders who could not cooperate with SGB, abnormal neck anatomy, and failure of stellate ganglion block refused to participate in the study.
