Newswise — SAN FRANCISCO (April 9, 2014) —Studies have shown that pain management in craniotomy patients is difficult. Physicians avoid prescribing narcotics — typically the medication of choice for pain management — because they impair the evaluation of brain function. Postoperative nausea and vomiting often delay the use of oral medication, and few nonnarcotic intravenous (IV) medications exist. However, the recently approved IV formulation of acetaminophen might present a safe, potent non-opioid choice for craniotomy patients.

A team of researchers led by Walavan Sivakumar, MD, conducted a double-blind, placebo-controlled trial of IV acetaminophen in post-craniotomy patients. Their study, titled Intravenous Acetaminophen for Postoperative Supratentorial Craniotomy – A Randomized, Double-Blinded, Placebo-Controlled Trial, found that patients received IV acetaminophen after a craniotomy had lower narcotic consumption overall and reported lower pain scores.

Dr. Sivakumar presented the team’s findings today during the 82nd Annual Scientific Meeting of the American Association of Neurological Surgeons (AANS).

Co-authors of the study include Paul House, MD, FAANS; Robert Hoesch, MD, PhD; Julie Martinez, RN; Nancy Duncan, NP-C; Safdar Ansari, MD; and Craig Kilburg, MD.

Founded in 1931 as the Harvey Cushing Society, the American Association of Neurological Surgeons (AANS) is a scientific and educational association with nearly 8,600 members worldwide. The AANS is dedicated to advancing the specialty of neurological surgery in order to provide the highest quality of neurosurgical care to the public. All active members of the AANS are certified by the American Board of Neurological Surgery, the Royal College of Physicians and Surgeons (Neurosurgery) of Canada or the Mexican Council of Neurological Surgery, AC. Neurological surgery is the medical specialty concerned with the prevention, diagnosis, treatment and rehabilitation of disorders that affect the entire nervous system including the spinal column, spinal cord, brain and peripheral nerves.
