Could a simple drug tame surgery inflammation in colon cancer patients?
NCT ID NCT06272461
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether giving lidocaine or ketamine during colorectal cancer surgery can lower inflammation (measured by a substance called IL-6) and help patients feel better after the operation. About 50 adults having open colorectal surgery will receive one of the two drugs for 24 hours. The goal is to see which drug reduces pain, nausea, and helps the bowel work again sooner.
