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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This study tests whether injecting a long-acting numbing medicine (bupivacaine) through chest tubes can safely reduce pain and lower the need for strong painkillers after heart bypass surgery. Sixty adults will receive either the numbing medicine or a saltwater placebo whenever their pain reaches a certain level. The goal is to see if this simple add-on approach improves recovery.

What this could mean

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

Active substance
bupivacaine (a numbing medicine)
What this could lead to
If it works, this could offer a simple, add-on way to reduce pain and the need for strong painkillers after heart surgery.
What could go wrong
This is a very early, small study (60 people) testing a short-term effect. It may not show a clear benefit, and results may not apply to all heart surgery patients.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age 18 years or older at the time of consent * Scheduled to undergo elective or semi-elective coronary artery bypass graft (CABG) surgery via midline sternotomy * Procedure involves the use of a mammary artery graft * Capable of providing informed written consent prior to surgery * Able to communicate pain scores using a numeric rating scale (NRS) These criteria ensure the study population is the clinically relevant group most likely to benefit from the intervention and that participants can provide valid consent and meaningful pain assessments. Exclusion Criteria: * Known allergy or hypersensitivity to bupivacaine or any amide-type local anesthetic * Emergency or urgent cardiac surgery where obtaining consent prior to the procedure is not feasible * Inability to communicate pain using numeric rating scale due to cognitive impairment, language barrier, or altered level of consciousness * Participation in another interventional clinical trial that may confound pain outcome These exclusion criteria are designed to protect participant safety, ensure the validity and interpretability of study outcomes (pain scoring ability), and maintain scientific rigor.
