Trial Summary

What is the purpose of this trial?

Post-cesarean section (CS) pain is commonly treated with acetaminophen, ibuprofen, and opioid medications as needed following delivery. About 300,000 women annually who were exposed to opioids after CS will go on to use opioids chronically. Reducing the quantity of post-CS opioids has been shown to decrease the amount of opioids used without compromising pain control. Bridge is a small device that sits on the outer ear and works similarly to a transcutaneous electrical nerve stimulation (TENS) unit to decrease pain sensation without medications. It has been shown to effectively reduce pain to decrease medication requirements after surgeries. This study aims to see if women receiving the Bridge device use need less pain medication than those without the device.

Treatment Details

Interventions

• Auricular Percutaneous Nerve Field Stimulator

Trial Overview The study tests a device called Bridge, which is placed on the ear and may help control pain without drugs, against a sham (fake) device. The goal is to see if using Bridge reduces the need for opioid medication after cesarean section.

Participant Groups

Group I: Bridge device Active Control 1 Intervention

Bridge device placed in post-anesthesia care unit (PACU) and worn until end-of-life of the device (at 5 days) in addition to standard of care pain medications as per institutional policy

Group II: Standard of care Active Control 1 Intervention

Standard of care pain medications only as per institutional policy

Group III: Sham device Placebo Group 1 Intervention

Sham (non-functional) Bridge device placed in post-anesthesia care unit (PACU) and worn until 5 days post-delivery in addition to standard of care pain medications as per institutional policy
