Postoperative Intravenous Patient-Controlled Analgesia in Thyroid Surgery: Comparison of Fentanyl and Ondansetron Regimens With and Without the Nonsteriodal Anti-Inflammatory Drug Ketorolac

Abstract

The NSAID ketorolac when combined with lower doses of the opioid fentanyl and the same dose of ondansetron is associated with the same analgesic efficacy but less nausea and vomiting after thyroid surgery. A higher ratio of NSAID to opioid, when used as reported here, is associated with less postoperative dizziness.
