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.

Completed This study
The trial has finished. Results may not be published yet.
Stopped early

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.

Summary

This study tested whether pressing on the esophagus with ultrasound guidance during face-mask ventilation can prevent stomach bloating. 103 adults having laparoscopic surgery were split into two groups: one with the pressure technique and one without. The goal was to see if the technique reduces stomach distension, which can complicate surgery.

What this could mean

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

What this could lead to
If successful, this technique could help prevent stomach bloating during mask ventilation, making surgery safer and easier.
What could go wrong
This is a small, completed observational study. Results may not apply to all patients or settings, and the technique requires ultrasound skill.

This is an AI summary of the original study and may miss details. Read our disclaimer.
