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 This study
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 Results may not be published yet.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

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 two drugs used to reverse muscle relaxants after surgery: sugammadex and a combination of neostigmine and glycopyrrolate. The goal was to see which one better prevents urinary retention in 124 patients having ear, nose, or throat surgery who were at high risk due to prior urinary issues, enlarged prostate, or prostate cancer. The researchers wanted to find out if sugammadex causes fewer problems with urination 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
sugammadex injection (Bridion) and neostigmine/glycopyrrolate injection
What this could lead to
If sugammadex works better, it could offer a safer way to reverse muscle relaxants after surgery, reducing the need for catheters in patients at risk of urinary retention.
What could go wrong
This is a small, completed study with 124 patients, so results may not apply to everyone. The benefit over standard care may be modest, and individual responses can vary.
