To the Editor,

Effective alternative pain therapies in the obstetric population are needed. Percutaneous nerve field stimulation (PNFS) has shown efficacy as a complementary method for postoperative pain management.1-3 In this pilot study, we assessed the feasibility and acceptability of the NSS2-BRIDGE® (Innovative Health Solutions, Versailles, IN, USA) auricular PNFS device for post-Cesarean delivery analgesia.

After Institutional Review Board approval, written informed consent was obtained ( NCT03830307, date of registration: February 5 2019). Inclusion criteria were ≥ 18 yr old, scheduled Cesarean delivery under single shot spinal anesthesia, and an American Society of Anesthesiologist physical status of II. Exclusion criteria were anxiety, active drug abuse, severe chronic pain, hemophilia, pacemaker, and psoriasis. Consecutive historical controls were identified from medical records of scheduled Cesarean deliveries and were matched by obstetrician and date of...



The authors are grateful to Innovative Solutions for the provision of the devices used in this study.
