STUDY DESIGN: Prospective randomized double-blind placebo-controlled study. OBJECTIVE: The objective of this study was to assess the efficacy of Ketorolac in reducing postoperative pain and morphine requirements following primary multilevel lumbar decompression surgery. SUMMARY OF BACKGROUND DATA: The use of opioid medications following surgical interventions can be complicated by related side effects such as respiratory depression, somnolence, urinary retention, and delayed time to oral intake. The use of Ketorolac, a potent nonopioid, nonsteroidal anti-inflammatory drug, is an attractive alternative to morphine as many of the opioid-related side effects can be avoided. METHODS: After Institutional Review Board approval, 25 patients who underwent a primary multilevel lumbar decompression procedure were randomly assigned to receive either Ketorolac or placebo in a double-blinded fashion. After surgery, all patients were allowed to receive intravenous morphine on an as needed basis. Morphine requirements were then recorded immediately postoperative, at 6, 12, and at 24 hours postoperative. A patient's overall hospital course morphine requirement was also assessed. Patient postoperative pain levels were determined using the Visual Analog Pain Scale and were documented at 4, 8, 12, 16, 24, and 36 hours postoperative. RESULTS: There were no significant differences in available patient demographics, intraoperative blood loss, or postoperative Hemovac drain output between study groups. Morphine equivalent requirements were significantly less at all predetermined time points in addition to the overall hospital morphine requirement in patients randomized to receive Ketorolac. Visual Analog Pain Scores were significantly lower in patients randomized to receive Ketorolac immediately postoperative in addition to 4, 12, and 16 hours postoperative. There were no identifiable postoperative complications associated with the use of Ketorolac. CONCLUSION.: Intravenous Ketorolac seems to be a safe and effective analgesic agent following multilevel lumbar decompressive laminectomy. Patients can expect lower morphine requirements and better pain scores throughout their postoperative course.

OBJECTIVES: Intravenous (IV) opioid titration is an accepted method of relieving acute renal colic. Studies have shown that nonsteroidal anti-inflammatory drugs (NSAIDs) are also effective in this setting. Our objective was to compare single-dose ketorolac and titrated meperidine, both administered intravenously, with respect to speed and degree of analgesia, adverse effects and functional status. Our primary hypothesis was that these agents provide equivalent analgesia within 60 minutes. Our secondary hypotheses were that ketorolac-treated patients would experience fewer adverse effects and would be better able to resume usual activity. METHODS: This was a multicentre, double-blind randomized equivalence trial in a convenience sample of patients age 18-65 with moderate or severe renal colic, documented by intravenous pyelogram, ultrasound or stone passage. Meperidine-treated patients received 50 mg IV meperidine at 0 minutes, then 25-50 mg every 15 minutes as needed for ongoing pain. Ketorolac-treated patients received 30 mg IV ketorolac at 0 minutes and placebo injections every 15 minutes as needed. Pain levels and adverse effects were assessed every 15 minutes, and functional status was evaluated at 60 minutes. Our primary outcome was the proportion of patients with mild or no pain at 60 minutes. RESULTS: Overall, 49 of 77 meperidine-treated patients (64%; 95% confidence interval [CI], 53%-75%) and 47 of 65 ketorolac-treated patients (72%; 95% CI, 61%-83%) achieved successful pain relief at 60 minutes (p value for equivalence = 0.002). Ten percent of meperidine-treated patients and 44% of ketorolac-treated patients were able to resume usual activity at 60 minutes (p = 0.001). CONCLUSIONS: In the doses studied, single-dose IV ketorolac is as effective as titrated IV meperidine for the relief of acute renal colic and causes less functional impairment.

BACKGROUND: Glucocorticoids are known to provide slower onset and more prolonged duration of analgesic effect than ketorolac. In the present study, we wanted to evaluate the effect over time from a single dose of either intravenous (i.v.) dexamethasone or an intramuscular (i.m.) depot formulation of betamethasone compared with i.v. ketorolac. MATERIALS AND METHODS: One hundred and seventy-nine patients admitted for mixed ambulatory surgery were included in the study. After induction of general i.v. anaesthesia, the patients were randomized to receive double-blindly either dexamethasone 4 mg i.v. (Group D) or betamethasone depot formulation 12 mg i.m. (Group B) or ketorolac 30 mg i.v. (Group K). Fentanyl was used for rescue analgesic medication in the post-operative care unit (PACU) and codeine with paracetamol after discharge, for a study period of 3 days. RESULTS: There was significantly less post-operative pain in the ketorolac group during the stay in the unit (88% with minor or less pain in Group K vs. 74% and 67% in Groups D and B, respectively, P < 0.05), significantly less need for rescue medication (P < 0.05) and significantly less nausea or vomiting (12% in Group K vs. 30% in the other groups pooled, P < 0.05). The ketorolac patients were significantly faster for ready discharge, median 165 min vs. 192 min and 203 min in Groups D and B, respectively (P < 0.01). There were no differences between the groups in perceived pain, nausea, vomiting or rescue analgesic consumption in the 4- to 72-h period. CONCLUSION: Dexamethasone 4 mg or bethamethasone 12 mg did not provide prolonged post-operative analgesic effect compared with ketorolac 30 mg, which was superior for analgesia and antiemesis in the PACU.
