Transcutaneous electrical stimulation at acupuncture points during abdominal surgery
Official title: Randomized Controlled Trial on the Effects of Transcutaneous Electroacupuncture on Brain Functional Connectivity in Postoperative Pain Patients Based on Electroencephalography
Run by Beijing Chao Yang Hospital · NCT07819630 · Data updated 2026-11-12
This study tests whether applying light electrical stimulation to specific acupuncture points around abdominal surgery can influence pain and vital signs in adults after surgery.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18–80 with ASA I–II undergoing abdominal surgery under general anesthesia and who consent to participate.
✕Probably not a fit
Patients with cognitive impairment, epilepsy, recent acupoint therapy, pacemakers or metal implants, or conditions affecting treatment safety may not benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Adults undergoing abdominal surgery under general anesthesia are randomized to receive percutaneous acupoint electrical stimulation at Neiguan, Hegu, and Zusanli or to a control condition. EEG is recorded with a 32-channel cap to monitor brain activity during the perioperative period, while hemodynamic parameters and pain scores are tracked. The trial aims to see if TEAS can modulate postoperative pain and physiological responses. The study is conducted at Beijing Chaoyang Hospital with informed consent from eligible participants.
Why it matters
Potential benefit: If successful, TEAS could offer a non-pharmacologic option to help manage postoperative pain and stabilize physiological responses after abdominal surgery.
How similar studies have gone: Previous research has explored TEAS for perioperative analgesia with mixed results, making this investigation another step in understanding its potential.
