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 whether a procedure called a stellate ganglion block—a targeted injection that numbs nerves in the neck using ultrasound guidance—can help prevent atrial fibrillation (an irregular heartbeat) after coronary artery bypass grafting surgery. Atrial fibrillation is a common complication after this type of heart surgery and can cause serious problems. The researchers want to see if this nerve block, given before surgery, can safely reduce how often this complication happens.
After bypass surgery, many patients develop an irregular heartbeat that can increase their hospital stay and risk of complications. There is currently no proven standard way to prevent this. This study is testing whether this nerve-blocking procedure might be a safe, simple way to reduce this common problem.

If you join this study, you will be randomly assigned to either receive the nerve block injection before your bypass surgery or to receive standard care without the block. The nerve block is given using ultrasound guidance as a single injection in the neck area before your operation. You will then proceed with your scheduled surgery as normal, and the study team will monitor you for complications, particularly any irregular heartbeat, during your hospital stay and follow-up visits.
