Transcutaneous Auricular Neurostimulation After Lumbar Surgery

Официальное название

Delivering Transcutaneous Auricular Neurostimulation as an Adjunct Non-Opioid Pain Management Therapy for Patients Undergoing Lumbar Surgery

Обзор

The purpose of this study, entitled "Delivering Transcutaneous Auricular Neurostimulation as an Adjunct Non-Opioid Pain Management Therapy for Patients Undergoing Lumbar Surgery", is to demonstrate whether transcutaneous auricular neurostimulation (tAN) can non-invasively reduce the perception of pain in patients undergoing lumbar surgery. tAN is placed on and around the ear to non-invasively stimulate branches of the vagus and trigeminal nerves and modulate specific brain regions associated with pain.

Подробное описание

This study is designed as a randomized, double-blind, sham-controlled, single-center, clinical trial in which 20 patients undergoing lumbar spine surgery will be randomized 1:1 into one of two treatment groups:

1. Group 1 (n=10): Active tAN + standard care 2. Group 2 (n=10): Sham tAN + standard care

Stimulation:

Participants undergoing lumbar surgery will be randomized to receive either active or sham tAN treatment according to the following time points:

* Pre-operative: 30 minutes in the hour prior to surgery * Intra-operative: 30 minutes before the end of surgery * Post-operative: 30 minutes at 3 and 6 hours after surgery * Inpatient: Four 30-minute sessions on Day 2

Blood Draws

Participants will have blood samples collected at the following time points:

* Day 1 (Day of Surgery) * Day 2 (Day 1 post-surgical)

Follow up Visits Participants will have study follow up visits on Days 7 and Day 14. These visits can either be conducted either via a secure telehealth video visit, or in person visit.

Вмешательства

• Устройство Sparrow Ascent Transcutaneous Auricular Neurostimulation (tAN)
  This method of simultaneous vagal and trigeminal stimulation via the external ear is known as transcutaneous auricular neurostimulation (tAN), as the targets of electrical stimulation include the auricular branch of the vagus nerve (ABVN) and auriculotemporal nerve (ATN), which is a branch of the mandibular division of the trigeminal nerve. Electrodes applied to select dermatome regions can target ear neural structures and deliver non-invasive vagus nerve stimulation (VNS) and trigeminal nerve s
• Устройство Sham Control Device
  This device looks like the active device, but no stimulation will be delivered.
