What the trial is, and whether it could suit you
This study aims to evaluate the efficacy and safety of transcutaneous auricular vagus nerve stimulation (taVNS) in patients with acute intracerebral hemorrhage (ICH). The taVNS intervention will be delivered using the BS-TVNS800-1 transcutaneous electrical stimulation therapy device (KERFUN, Shanxi, China). A total of 186 patients will be randomly assigned in a 1:1 ratio to either the taVNS group or the sham-taVNS group. The primary outcome is the relative volume of perihematoma edema assessed on day 10-14 after randomization. Adverse events associated with taVNS therapy will be systematically evaluated to assess its safety profile.
