Liver surgery patients studied for paracetamol safety
NCT ID NCT03297073
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how paracetamol (a common painkiller) is processed in the body after major liver surgery. Researchers measured paracetamol levels in the blood over five days in 90 patients who had different amounts of liver removed. The goal was to understand if patients with less liver tissue are at higher risk of paracetamol toxicity, helping guide safer pain management after surgery.
