What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 compares two AI models, Gemini 2.5 Pro and ChatGPT-5.1, against expert anesthesiologists in interpreting ultrasound videos of a pain-block procedure called TAP block. Forty adults having surgery will have their routine TAP block recorded, and the AI will analyze the videos to identify anatomy and assess success. No extra procedures are needed for participants. The goal is to see if AI can reliably support clinicians in ultrasound-guided anesthesia.

What this could mean

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

Active substance
Artificial intelligence models (Gemini 2.5 Pro and ChatGPT-5.1) analyzing ultrasound videos
What this could lead to
If successful, this could show that AI can help doctors interpret ultrasound images for nerve blocks, potentially improving training and decision-making in anesthesia.
What could go wrong
This is a small, early-stage study with only 40 participants. The AI models may not perform as well as experts, and results may not apply to other types of ultrasound or medical settings.

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

Participants

About 40 people

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

Started

Expected to finish

May 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.

Who is studied

This study will include adult surgical patients who receive a lateral Transversus Abdominis Plane (L-TAP) block as part of routine anesthesia practice during elective operations. The population consists only of patients whose block procedures are already clinically indicated and performed by experienced anesthesiologists. No additional procedures are carried out for research purposes. Ultrasound videos obtained during standard block practice are de-identified and analyzed. The study does not involve patient follow-up or any change in clinical management.

Ages

18 to 85 years

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Inclusion Criteria: * Adults aged 18-85 years * ASA I-III physical status * Undergoing elective surgery with a lateral TAP block performed as part of routine anesthesia care * Complete ultrasound-guided block procedure recorded on video * Able to provide written informed consent Exclusion Criteria: * Unsuccessful or incomplete TAP block procedure * Poor-quality ultrasound video (needle tip or anesthetic spread not visible) * Missing demographic or clinical data * Withdrawal of consent at any time
