Study ObjectiveTo evaluate the usefulness of ketorolac in the treatment of intraoperative pain refractory to the administration of local anesthetic alone.DesignIntraoperative acute-pain treatment model consisting of awake, nonsedated patients who randomly received either an opioid or a study drug in a double-blind fashion.SettingUniversity medical center.PatientsEighty patients who underwent breast biopsy, lumpectomy, or central venous catheter placement.InterventionsPatients received either ketorolac 1 mg/kg intravenously (IV) up to a total dose of 60 mg or fentanyl 3 micrograms/kg IV up to a total dose of 250 micrograms to supplement the local anesthetic.Measurements And Main ResultsVerbal pain evaluation and the visual analog scale (VAS) were used for perioperative measurement of pain. Heart rate (HR), blood pressure, and respiratory rate (RR) were recorded before and after analgesic drug injections at 10-minute intervals, both intraoperatively and while the patient was in the postanesthesia care unit (PACU). Speed of recovery was quantified by p-deletion and digit substitution tests on admission to the PACU and at 30-minute intervals until discharge. The frequency of nausea, vomiting, and pruritus were recorded. There were no differences between the groups in perioperative verbal pain evaluation, VAS scores, HR, systolic blood pressure, diastolic blood pressure, or RR. Patients who received ketorolac exhibited a significantly lower frequency of intraoperative and postoperative medication administration intraoperatively, than those who received fentanyl. No additional pain medication was required by patients in the PACU in either group.ConclusionsKetorolac is a useful alternative to fentanyl for the treatment of intraoperative pain refractory to the administration of local anesthetic alone during monitored anesthesia care. A decided advantage of ketorolac over fentanyl is the absence of nausea and vomiting in the intraoperative and postoperative periods.
