Intravenous acetaminophen for postoperative supratentorial craniotomy pain: a prospective, randomized, double-blinded, placebo-controlled trial

Restricted access

In Brief

The authors designed a randomized, double-blinded, placebo-controlled trial to evaluate intravenous acetaminophen as a scheduled adjunct with our standardized craniotomy pain control regimen. No statistically significant effect was found in narcotic consumption at 24 or 48 hours after surgery. At 24 but not 48 hours, patients treated with intravenous acetaminophen did report significantly lower pain scores than patients given the placebo. These data provide only modest support for using intravenous acetaminophen to improve postoperative craniotomy pain.

ABBREVIATIONS IV = intravenous; NCC = neurocritical care; VAS = visual analog scale.

    Patient-reported pain scores over time. At 24 hours, the difference in patient-reported pain scores between the two groups was significant (p < 0.001). The difference was no longer significant at 48 hours.
