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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Chronic pain after heart surgery through a breastbone incision affects many patients and can last for years. Researchers are testing whether an ultrasound-guided nerve block, given after anaesthesia but before the first cut, can reduce the chance of chronic pain three months later. The trial will randomly assign 174 adults having elective heart surgery to receive the block plus standard pain relief, or standard pain relief alone. The main measure is whether participants still report chest pain three months 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
A nerve block using the local anaesthetic bupivacaine, injected around the nerves beside the breastbone before surgery
What this could lead to
If it works, this could offer a simple way to reduce long-term chest pain after heart surgery, using a nerve block that is already available.
What could go wrong
The block may not prevent chronic pain, or the benefit may be small. Nerve blocks carry small risks of bleeding, infection, or allergic reaction, and results from one hospital may not apply everywhere.
