What this trial studies

This interventional study uses an ultrasound-guided, power-assisted needle insertion device to guide clinicians placing two needles into arteriovenous fistulas (AVF) or grafts (AVG) at the start of dialysis. Eligible adults must have a forearm or upper-arm AVF/AVG that is actively used and meet ultrasound criteria for diameter (8–12 mm) and depth (≤6 mm). The device is intended to assist the cannulator in locating the access and inserting needles while participants report pain using a validated scale. The trial is being conducted at a single site in Tashkent, Uzbekistan.

Who should consider this trial

Good fit: Adults (≥18 years) on hemodialysis with a forearm or upper-arm AVF or AVG that is actively used and meets ultrasound criteria (8–12 mm diameter and ≤6 mm depth), who can consent and report pain, are ideal candidates.

Not a fit: Patients with AVFs/AVGs that are too deep or too small, or with aneurysms, stenosis, thrombosis, stents, conditions interfering with ultrasound imaging, pregnant or breastfeeding individuals, and those under 18 are unlikely to benefit.

Why it matters

Potential benefit: If successful, the device could make cannulation more accurate, faster, and less painful, potentially reducing infiltration and other access complications.

How similar studies have performed: Previous studies have shown that ultrasound guidance improves vascular access success, but the specific use of a power-assisted guided insertion device for AVF/AVG cannulation is relatively novel and less well studied.
