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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.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 trial is testing whether using a lower or higher flow of fresh gas during general anesthesia affects how well the lungs recover after laparoscopic gallbladder removal. About 120 adults having this surgery will be randomly assigned to receive either low-flow (0.5 L/min) or high-flow (4 L/min) anesthesia. The researchers will use lung ultrasound 30 minutes after the breathing tube is removed to measure lung aeration and check for collapse (atelectasis). The goal is to see if one approach leads to better lung function 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
Low or high fresh gas flow during general anesthesia
What this could lead to
If low-flow anesthesia proves better, it could reduce lung complications after surgery and improve recovery for patients undergoing laparoscopic procedures.
What could go wrong
This is a small, early-stage trial, and results may not apply to all surgeries or patients. The difference between gas flows might be too small to matter clinically.
