Is this trial a fit for you?

Likely a good fit

Ideal candidates are female patients aged 18-65 undergoing elective laparoscopic surgery with an ASA Grade of 1 to 3.

Probably not a fit

Patients with upper extremity nerve injuries, severe central nervous system diseases, or those requiring ICU care post-surgery may not benefit from this study.

What this trial studies

This study evaluates the effectiveness of percutaneous electrical nerve stimulation at the Pericardium 6 (PC6) point using a wearable device to prevent postoperative nausea and vomiting in patients undergoing elective laparoscopic surgery. Approximately 302 participants will be randomly assigned to receive either active electrical stimulation or a placebo wristband. The stimulation will occur 30 minutes before surgery and continue for 24 hours postoperatively. The primary outcome is the incidence of postoperative nausea and vomiting, with secondary outcomes including recovery metrics and complications.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of postoperative nausea and vomiting, improving patient comfort and recovery.

How similar studies have gone: Other studies have shown promise in using electrical stimulation for nausea prevention, but this specific approach is novel.
