A completed Phase II RCT from Peking Union Medical College Hospital has investigated whether the EmeTerm wearable electrical stimulation bracelet, targeting the PC6 acupoint, can reduce PONV incidence in female patients undergoing laparoscopic surgery under general anaesthesia. With 326 participants enrolled and results anticipated in 2025–2026, this trial could reshape non-pharmacological adjuncts in perioperative antiemetic bundles.
