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 Results may not be published yet.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

Summary

This pilot study tested a device called the Learning Intravenous Resuscitator (LIR) that automatically gives IV fluids during major abdominal surgery under general anesthesia. The goal was to see if the device could keep blood volume stable as well as a human anesthesiologist. Only 30 patients were planned, but the study was terminated early, so results are limited.

What this could mean

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

Active substance
Learning Intravenous Resuscitator (LIR) system (device)
What this could lead to
If successful, this could lead to a device that automatically manages IV fluids during surgery, potentially reducing human error and improving patient stability.
What could go wrong
This is a very small, early pilot study that was terminated, so results are limited. The device requires constant supervision and may malfunction or be overridden by the anesthesiologist.
