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 Results may not be published yet.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.

Summary

This study tested whether transcutaneous electrical acupoint stimulation (TEAS) — a mild electrical pulse on specific acupoints — could reduce postoperative delirium (confusion) in 226 elderly patients having abdominal surgery. Researchers also looked at brain wave (EEG) changes to understand how it might work. The goal is to find a simple, drug-free way to protect older patients' mental clarity after surgery.

What this could mean

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

Active substance
transcutaneous electrical acupoint stimulation (TEAS)
What this could lead to
If it works, this could offer a simple, non-drug way to lower the risk of confusion after surgery in older adults.
What could go wrong
This is a small, completed study with no phase designation, so results are preliminary. The effect on delirium and EEG changes may not be strong or widely applicable.
