Can a herbal bath cut Post-Surgery painkiller use?
NCT ID NCT07744594
First seen Aug 04, 2026 · Last updated Aug 05, 2026 · Updated 1 time
Summary
This trial tests whether adding a traditional Chinese medicine (TCM) sitz bath to standard pain management can better ease pain after perianal abscess surgery. Adults scheduled for this surgery will be randomly assigned to receive either standard care or standard care plus the herbal bath. The study will compare pain scores, painkiller use, and quality of life to see if the combined approach offers meaningful benefits.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Traditional Chinese medicine sitz bath
- What this could lead to
- If effective, this combined approach could offer a safer, more personalized way to manage post-surgical pain, reducing reliance on opioids and improving recovery.
- What could go wrong
- This is a single-center trial, and results may not apply broadly. The open-label design and lack of blinding could introduce bias, and the TCM bath's benefits beyond standard care remain uncertain.
