Effect of transcutaneous auricular vagus nerve stimulation on postoperative pain in patients undergoing thoracoscopic partial lung resection: a randomized, double-blind, controlled clinical trial.

A randomized double-blind controlled trial investigated whether transcutaneous auricular vagus nerve stimulation (taVNS) could reduce postoperative pain in patients recovering from thoracoscopic partial lung resection. Findings indicated that taVNS treatment produced meaningful reductions in pain levels compared to sham controls following this type of minimally invasive thoracic surgery. These results suggest taVNS may be a viable non-pharmacological adjunct for postoperative pain management in surgical patients.
