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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.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 looks at how GLP-1 receptor agonists (like Ozempic or Wegovy) affect how fast the stomach empties before surgery. These drugs are used for weight loss and diabetes, but they slow stomach emptying, which could raise the risk of food or liquid entering the lungs during anesthesia. Researchers will use ultrasound to measure stomach contents in 100 patients taking GLP-1 drugs before elective surgery. The goal is to find out if these patients need longer fasting times to stay safe.

What this could mean

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

Active substance
Glucagon-like peptide-1 receptor agonists (GLP-1 RAs)
What this could lead to
If successful, this could lead to specific fasting guidelines for patients on GLP-1 drugs before surgery, reducing the risk of aspiration.
What could go wrong
This is a small, early observational study (100 participants) that only measures stomach size by ultrasound, not actual aspiration events. Results may not apply to all patients or surgeries.

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.

Inclusion Criteria: * Adult patients who are receiving Glucagon-like peptide-1 Receptor Agonist medication and scheduled for any elective surgery or procedure under anesthesia. * The patient has provided informed consent for the study Exclusion Criteria: * Pregnant patients * Patients with abnormal gastric anatomy like previous gastric resection or bypass( gastric band in situ, previous fundoplication, hiatus hernia * Inability to consent * Emergency surgery * Cognitive impairment (due to the mixed reasons of potential misunderstanding of the aim of the study and inability to provide informed consent, potential inability to provide detailed fasting regimen before the surgery, potential for impaired use of GLP-1 agonists before the surgery) * Terminal illness (due to the effect of chronic illness on the physiologic functions of gastrointestinal tract and gastric emptying)
