Trial Outcomes & Findings for BRIDGE Percutaneous Nerve Stimulation for Cesarean Delivery Pain Control (NCT NCT04365465)

NCT ID: NCT04365465

Last Updated: 2023-01-18

Results Overview

Pain Score with movement will be measured by a score on a scale (0=no pain 10=most pain). The minimum value is 0 and the maximum value is 10. Higher scores mean a worse outcome.

Measure
Active Device
Participants in this arm will receive an active NSS-Bridge device placed immediately following their cesarean section. NSS-2 Bridge: The NSS-2 BRIDGE (Appendix 1) is a battery operated and disposable percutaneous auricular nerve field stimulator (Innovative Health Solutions, Versailles, IN, USA), that was recently cleared by the FDA and assigned a Class II Risk Designation; a class which includes surgical drapes, pumps and power wheelchairs.
Placebo Device
Participants in this arm will receive an inactive (sham) NSS-Bridge device placed immediately following their cesarean section. Inactive NSS-2 Bridge: This is a sham device which is identical to the active NSS-2 Bridge, but will not provide percutaneous auricular nerve field stimulation when applied.
Active Control
Participants in this arm will receive no device, only the standard postpartum pain control. Active control: Active control will include standard of care pain management during the postoperative period. Participants in this intervention arm will not receive or wear a device.

SECONDARY outcome

Timeframe: Post-operative day 3

PROMIS Pain Intensity Survey is self-reported by participants and includes the options: "Had no pain", "Mild", "Moderate", "Severe", or "Very Severe". These responses range from 1 point (had no pain) to 5 points (very severe). This means the participant raw score can be between 3 points and 15 points.
