NCT ID NCT03090776

First seen Jul 20, 2026 · Last updated Jul 21, 2026 · Updated 1 time

Summary

This trial tests whether giving a low dose of ketamine during mastectomy surgery can prevent persistent pain that often follows the procedure. Women scheduled for partial or total mastectomy receive either ketamine or a placebo saline infusion while under general anesthesia. Researchers then track pain levels and opioid use for up to one year after surgery to see if ketamine reduces both short-term and long-term pain.

What this could lead to
If it works, this could offer a simple way to prevent chronic pain after mastectomy and reduce reliance on opioids.
