This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing a pain-relief technique called a rectus sheath block for patients undergoing heart surgery. A rectus sheath block is a numbing injection that targets nerves in your abdominal wall to reduce pain after surgery. Researchers want to see if this treatment can lower both pain levels and the amount of opioid pain medication patients need after their operation.
After heart surgery, patients typically experience significant pain and often require strong opioid medications to manage it. This study exists to find out whether this medication-free numbing technique could provide better pain control while reducing reliance on opioids, which can have side effects and risks.

If you enroll, you will be randomly assigned to either receive the rectus sheath block procedure or to a control group that does not receive it. The block would be given after your heart surgery as part of your pain management plan. Researchers will then measure your pain levels and track how much pain medication you use during your recovery to compare the two groups.
