Brief Summary
This study compares two local anesthetics, ropivacaine and lidocaine, for patients undergoing arteriovenous fistula surgery. Arteriovenous fistula is the preferred vascular access for end-stage kidney disease patients needing hemodialysis. In this clinical trial, patients are randomly assigned to receive either ropivacaine or lidocaine for local anesthesia during the surgery. Researchers are evaluating which medication provides better pain control and improves surgical outcomes. The study is examining:
- Pain levels during and after surgery
- Surgery duration
- Need for additional pain medication
- Surgical complications
- Fistula development over time
- Long-term fistula function at 1 year and 5 years This is a double-blind study, meaning neither patients nor surgeons know which medication is being used. The study is currently ongoing with active patient follow-up and is expected to be completed in June 2026. Patients are being followed for up to 5 years to monitor their long-term progress. This research may help doctors choose the best local anesthetic for arteriovenous fistula surgery, potentially leading to better pain control and improved long-term outcomes for kidney disease patients.

- Masking Details
- This is a double-blind study where both patients and surgeons are blinded to the intervention. The anesthetic preparations are performed by resident physicians, circulating nurses, and scrub nurses who are not involved in outcomes assessment. The allocation assignments are concealed in sequentially numbered, opaque, sealed envelopes that are opened immediately prior to anesthesia administration.
