The Efficacy of Intravenous Acetaminophen During Perioperative Neurosurgery Period

Completed · Phase 4 · Has a placebo group

Conditions studied: Craniotomy, Brain Surgery

In brief

This is a prospective randomized double blinded trial study involving 128 patients undergoing any craniotomy procedure at Evanston Hospital. The patients will be randomized by the sealed envelope technique. The anesthesiologist and nurses who will be administering the placebo or intravenous acetaminophen will be blinded to the group in which patients are assigned. The following general perioperative data will be recorded: patient information/preoperative data, procedural information, postoperative information, and overall satisfaction of pain management at 24 hours after surgery. Based on a pilot study (N-20) we expect that 25% of the placebo treated patients will require no opioids in the first 24 hour postoperative period. With the use of intravenous acetaminophen, it is hypothesized that the number of patients that do not require opioids in the first 24 hours after surgery will double.
