Electroacupuncture Plus 5-HT3 Receptor Inhibitor for PONV Prevention in High-Risk Patients Undergoing Thoracoscopic Lung Cancer Surgery
Sponsor: Shanghai Chest Hospital
Summary
This prospective, randomized controlled study aims to evaluate the efficacy and safety of electroacupuncture combined with 5-HT3 receptor inhibitor for preventing postoperative nausea and vomiting (PONV) in high-risk patients undergoing thoracoscopic lung cancer surgery. The primary outcome is the incidence of PONV within 24 hours after surgery.

Electroacupuncture
EA is performed at two time points: 30 minutes before anesthesia induction and 4 hours postoperatively, with each session lasting 30 minutes. Bilateral acupoints including PC6, LI4, and ST36 are selected. Disposable stainless-steel needles are inserted through fixed insulating pads to a depth of approximately 10 mm. Manual manipulations are applied until deqi (the needling sensation) is achieved. An electroacupuncture device (Hwato SDZ-III) is connected for electrical stimulation.
Sham electroacupuncture
Sham electroacupuncture (SA) is performed using a non-therapeutic placebo acupuncture device (sham needle) at the same time points, acupoint locations as the EA group, paired with fixed insulating pads. The placebo needle mimics the appearance and tactile sensation of real needles without true skin penetration or therapeutic depth; no manual manipulation is conducted to achieve deqi, and no electrical stimulation is applied via the electroacupuncture device.
