Effect of Transcutaneous Auricular Vagal Nerve Stimulation on Acute Pancreatitis

"Patients will receive taVNS at left tragus (a device developed by the Engineering Research Center of Molecular and Neuro Imaging, Ministry of Education (School of Life Science and Technology, Xidian University), in collaboration with the Wearable BCI and Intelligent Rehabilitation Innovation Lab (Guangzhou Institute of Technology, Xidian University)) twice daily (morning and night) for 30 minutes per session over a period of up to 7 days. The stimulation parameters are as follows:~* Duty circle: 30s on periods alternating with 30s off periods;~* Frequency: 25 Hz;~* Amplitude: 0-2 mA (adjusted to the maximum tolerated level for each patient);~* Pulse width: 0.5 ms."
