Auricular VNS Following Intracerebral Hemorrhage

Summary

This study will evaluate whether non-invasive auricular vagal nerve stimulation lowers inflammatory markers, and improves outcomes following intracerebral hemorrhage.

Detailed Description

Vagal nerve stimulation (VNS) has been studied as a novel method of reducing inflammation, and it has been successfully used in animal models of inflammatory conditions. The purpose of the proposed study is to determine if transcutaneous auricular VNS will impact inflammatory markers in the blood and cerebrospinal fluid (CSF) in patients with intracerebral hemorrhage, and how it impacts their clinical course and outcomes. This study will involve randomizing patients to stimulation with VNS, or sham stimulation. Blood and CSF will be collected on admission, and serially throughout the patient's admission. Clinical events tracked during the hospital stay include the development of peri-hematomal edema, interventions for edema (medical or surgical), and intensive care unit and hospital stay. Outcomes following admission will include functional scores at discharge, and at follow-up visits for up to 2 years after discharge. No additional appointments will be made specially for the research study.
