What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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 Results may not be published yet.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
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 tests whether a rectus sheath block, a type of nerve block using local anesthetic, can reduce pain and the need for opioid painkillers after cardiac surgery. Researchers will compare opioid use and pain scores in 75 adults who receive the block versus those who do not. The goal is to improve pain control and potentially speed recovery.

What this could mean

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

Active substance
rectus sheath block (a nerve block with local anesthetic)
What this could lead to
If it works, this could offer a better way to manage pain after heart surgery, reducing the need for strong painkillers.
What could go wrong
This is a small, early-stage trial with only 75 participants. The block may not significantly reduce pain or opioid use, and results may not apply to all heart surgery patients.
