TEAS for Variceal Bleeding Endoscopy in Cirrhosis
China180 participantsStarted 2025-07-18
Plain-language summary
This randomized controlled trial evaluates whether transcutaneous electrical acupoint stimulation (TEAS) improves procedural success and patient tolerance in cirrhotic patients undergoing urgent unsedated endoscopy for suspected variceal bleeding.
Participants with cirrhosis and suspected acute variceal bleeding requiring urgent endoscopy are randomly assigned to one of three groups:
1. Active TEAS: Electrical stimulation at bilateral Hegu (LI4), Neiguan (PC6), Zusanli (ST36), and Gongsun (SP4) starting 30 minutes before endoscopy and continuing until 15 minutes after the procedure.
2. Sham TEAS: Identical electrode placement but no electrical current.
3. Control: Standard endoscopy alone without electrodes.
All patients receive topical pharyngeal anesthesia and standardized medical management. The study assesses procedural success (composite of technical adequacy and patient satisfaction), patient discomfort (visual analogue scale), procedure time, hemostasis outcomes, physiological parameters, and clinical experience measures.
