A novel wearable device significantly outperforms metoclopramide in managing moderate to severe postoperative nausea and vomiting (PONV).

• The TEAS group achieved a 2-hour remission rate of 77.6% vs. 55.2% for controls (p < 0.001).
• 24-hour relapse rates were 12.2% for TEAS compared to 56.3% for metoclopramide (p < 0.001).

This suggests wearable TEAS could enhance recovery from anesthesia, offering surgeons a valuable non-pharmacological option for PONV management.
