Summary

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.

Conditions

  • Intracerebral Hemorrhage

Interventions

DEVICE

transcutaneous auricular vagus nerve stimulation device

Place the stimulation device on the left auricle and set the stimulation parameters according to the following conditions: a. Waveform: biphase, square wave; b. Wave width: 200 μs; c. Frequency: Alternating between low frequency (4 Hz for 4 s), high frequency (40 Hz for 8 s), and a 4 s pause; d. Intensity: The maximum intensity that induces the strongest sensation the individual can tolerate without causing pain, usually 1.5-3.5 mA; e. Treatment duration: Each treatment lasted 30 minutes, twice daily (8:00, 16:00) for 10 days.

DEVICE

Sham device

The sham taVNS group received the same parameters with a current intensity of 0.06 mA.
