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

In 30 seconds

This randomized controlled trial evaluated the effects of transcutaneous auricular vagus nerve stimulation (taVNS) on postoperative pain in 119 patients undergoing thoracoscopic partial lung resection. Active taVNS significantly reduced cough pain scores at 24h, 48h, and 72h post-surgery, and decreased cumulative opioid use (p < 0.05).

Key findings

• Active taVNS reduced cough pain scores at 24h, 48h, and 72h post-surgery (p < 0.05).
• Cumulative postoperative opioid use was significantly lower at 24h and 72h with active taVNS (p < 0.05).
• Active taVNS was associated with a lower incidence of postoperative pneumothorax (p < 0.05).

Why it matters

Effective management of postoperative pain is crucial for recovery after thoracic surgery. This study suggests that taVNS may provide a noninvasive option to reduce pain and opioid consumption, potentially improving patient outcomes.
