Needle vs. scalpel: which dialysis access works best?
Disease control OngoingThis study compares two methods for creating an arteriovenous fistula (AVF) in people with end-stage kidney disease who need dialysis. The newer endovascular method uses a needle through the skin, while the traditional surgical method requires an incision. Researchers will enroll…

New balloon could save dialysis patients from repeat surgeries
Disease control OngoingThis study tests a special balloon coated with the drug paclitaxel to treat blockages in arm fistulas used for dialysis. The balloon is inflated to open the narrowed blood vessel and release the drug to help keep it open. Researchers will check if the fistula stays open without n…

Can a deep breath and a hint of lemongrass take the sting out of dialysis needles?
Symptom relief OngoingPeople on hemodialysis receive needle sticks through a fistula or graft several times a week, and the pain and anxiety can build over time. This trial tests whether slow, deep breathing combined with lemongrass aromatherapy reduces pain and anxiety during needle insertion. Resear…

Ice pack on hand may ease dialysis needle pain without drugs
Symptom relief OngoingPeople on hemodialysis need their fistula punctured with a needle three times a week, which can be painful and anxiety-provoking. This trial compares three approaches: usual care, applying an ice pack to a specific point on the hand before the needle, and using a numbing gel. Res…
