Summary

This study aimed to see if adding ketamine to standard anesthesia during endometriosis surgery could lower pain afterward. It was designed for adults with chronic pelvic pain and central sensitization, but the trial was withdrawn before enrolling any participants. No results are available.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
ketamine
What this could lead to
If it had worked, this could point toward a way to reduce post-surgery pain for endometriosis patients using a common anesthetic.
What could go wrong
The study was withdrawn before any participants were enrolled, so no results are available. Ketamine can cause side effects like hallucinations or nausea, and its benefit for this specific pain type is unproven.
