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.
