NCT ID NCT01739699

First seen Jun 27, 2026 ยท Last updated Jun 27, 2026

Summary

This study tested whether giving intravenous acetaminophen (Tylenol) during and after brain surgery could reduce the need for opioid painkillers. 140 adults having open brain surgery were randomly assigned to receive either IV Tylenol or a placebo. The main goal was to see if more patients in the Tylenol group could avoid opioids entirely in the first 24 hours after surgery.
