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 Results may not be published yet.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

Summary

This study tests whether applying mild electrical stimulation to specific acupoints on the wrist before anesthesia can prevent low blood pressure in older adults undergoing surgery. Researchers will compare high-frequency versus low-frequency stimulation in 84 participants aged 65 and older. The goal is to see if this simple, non-drug approach can help maintain stable blood pressure during the critical induction phase of anesthesia.

What this could mean

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

Active substance
electrical acupoint stimulation
What this could lead to
If it works, this could offer a simple, drug-free way to reduce the risk of dangerously low blood pressure during surgery in older adults.
What could go wrong
This is a small, early-stage trial with only 84 participants, so results may not apply to everyone. The effect may be small or no different from placebo.

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 204 people

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

Expected to start

Sep 2026

An estimate. Start dates often move.

Expected to finish

Mar 2027

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.
