    AbstractWe present a case series to demonstrate proof-of-concept for the off-label use of an auricular neuromodulation device-originally developed to treat symptoms associated with opioid withdrawal-to instead provide analgesia and opioid-sparing following knee and hip arthroplasties. Within the recovery room, an auricular neuromodulation device (near-field stimulator system 2 [NSS-2] Bridge, Masimo) was applied to 5 patients. Average daily pain at rest and while moving was a median of 0 to 2 as measured on the 0 to 10 numeric rating scale, while median daily oxycodone use was 0 to 2.5 mg until device removal at home on postoperative day 5. One patient avoided opioid use entirely.Copyright © 2022 The Author(s). Published by Wolters Kluwer Health, Inc. on behalf of the International Anesthesia Research Society.
