Interventions and Outcome Measures

Arms

experimental: Active tAN + standard of care

Participants randomized to the active group will have an earpiece applied and receive 30 minutes of active tAN therapy immediately prior to the dialysis port placement procedure. When the 30-minute tAN session is complete, the system will be turned off, unplugged, and the earpiece will be removed.

sham comparator: Sham tAN + standard of care

Participants randomized to the sham group will have an earpiece applied, but stimulation will not be turned on. These participants will receive 30 minutes of sham tAN therapy immediately prior to the dialysis port placement procedure. When the 30-minute tAN session is complete, the system will be turned off, unplugged, and the earpiece will be removed.

Interventions

Volta tAN System

Transcutaneous auricular neurostimulation (tAN)

SHAM Volta tAN System

Participants randomized to the sham group will have an earpiece applied, but stimulation will not be turned on.

Primary outcome measure
