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 Results may not be published yet.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.

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 specific nerve block, called the serratus posterior superior intercostal plane block, can reduce pain and opioid use after minimally invasive heart bypass surgery. Sixty adults undergoing this surgery will be randomly assigned to receive either the nerve block with bupivacaine or standard anesthesia alone. The main goal is to see if the block improves overall recovery quality and reduces the need for painkillers.

What this could mean

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

Active substance
bupivacaine
What this could lead to
If effective, this nerve block could become a standard way to manage pain after heart surgery, reducing reliance on opioids and speeding recovery.
What could go wrong
This is a small, early-stage study with only 60 participants. The block may not provide significant pain relief, and there are risks like bleeding or infection at the injection site.
