Summary

To explore the effects of transcutaneous auricular vagus nerve stimulation (taVNS) during the perioperative period on the incidence of delayed gastric emptying after pancreatoduodenectomy and its possible mechanisms.

Conditions

  • Delayed Gastric Emptying

Interventions

DEVICE

Transcutaneous Auricular Vagus Nerve Stimulator

Intervention Timing of Transcutaneous Auricular Vagus Nerve Stimulator: The intervention will begin 30 minutes before anesthesia induction and continue until the end of the surgery, terminating after the removal of the endotracheal tube in the PACU. The stimulation parameters are set as follows: frequency 25 Hz, pulse width 200 μs, 30 seconds on / 30 seconds off, with the current intensity set to the maximum amplitude the patient can tolerate (just below the pain threshold).
