ClinConnect Summary

This clinical trial is studying the use of ultrasound technology to help doctors successfully access arteriovenous fistulas (AVFs) in patients with end-stage kidney disease who need hemodialysis. AVFs are important for dialysis treatment, but sometimes they can be difficult to access, especially after multiple failed attempts. The trial aims to see if using ultrasound can reduce the number of complications and failures during the first cannulation, which is when the needle is inserted into the AVF for the first time.

To be eligible for this study, participants should be at least 20 years old and have had their AVF for more than 8 weeks. They should have experienced at least two failed attempts at cannulation, resulting in bruising or swelling around the access site. Participants will undergo an evaluation to ensure that their blood vessels are suitable for the procedure. If you join the trial, you can expect to receive care that uses ultrasound to guide the needle placement, which may lead to better outcomes and fewer complications. This study is important because it could improve how dialysis access is managed, ultimately benefiting patients relying on these procedures for their treatment.
