Acupoint Stimulation Improves Postoperative Wound Pain

This intervention involves acupoint stimulation and auricular acupressure. Stimulation of selected body acupoints is administered by trained personnel following a standardized protocol. The intervention is provided once daily for three consecutive days, beginning post-surgery. For auricular acupressure, additional auricular points are chosen based on the involved abdominal organ and its corresponding viscera-meridian locations on the auricle. Vaccaria seeds are applied to the selected points with adhesive patches, and patients are instructed to apply pressure to the points regularly throughout the day.

Participants in this group will receive a sham acupoint stimulation procedure. Acupoint stimulation will be using identical procedures to the experimental group, without applying pressure. No stimulation or manipulation was performed. The frequency and timing of the sham intervention matched that of the experimental group.
