Earpiece zaps nerves to curb bleeding in dialysis surgery

NCT ID NCT06647017

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether a device that gently stimulates a nerve in the ear can reduce blood loss during surgery to place a dialysis graft. Forty adults undergoing this procedure will be randomly assigned to receive either the active stimulation or a sham (inactive) device. Researchers will measure total blood loss, surgery time, and time to stop bleeding.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Volta tAN System (Sparrow Ascent) - a device that delivers mild electrical stimulation to the ear

What this could lead to

If it works, this could give surgeons a simple, non-drug way to reduce bleeding during dialysis access surgery.

What could go wrong

This is a very small early study (40 people) testing a device for a short-term effect. The sham group may show similar results, and the device may not reduce blood loss meaningfully.
