Comparing two sedation approaches during liver cancer heat treatment

This trial is testing whether adding lidocaine—a numbing medication—to standard sedation (propofol and fentanyl) during a minimally invasive heat treatment for liver cancer can reduce inflammation and improve outcomes. Researchers want to understand if the medication helps protect your body's response during the procedure and potentially leads to better healing.

When doctors treat early-stage liver cancer with radiofrequency ablation (a heat-based technique), the procedure can trigger inflammation in your body. This trial exists to see if adding this medication to standard sedation might reduce that inflammatory response and improve safety or recovery.
