Electroencephalogram Changes Induced by Transcutaneous Electrical Acupoint Stimulation

Resumen breve

A total of 90 subjects underwent abdominal surgery under general anesthesia at Chaoyang Hospital in Beijing. The subjects were divided into a percutaneous acupoint electrical stimulation group and a control group. The subjects were selected for TEAS stimulation at the Neiguan, Hegu, and Zusanli acupoints on both sides, and EEG data were collected using a 32 lead EEG cap test throughout the entire process. During the experiment, changes in hemodynamic parameters (blood pressure, heart rate) and perioperative pain scores of the subjects will be recorded.
