Randomized Controlled Trial Comparative Study Clinical TrialComparative effects of ketorolac, dezocine, and fentanyl as adjuvants during outpatient anesthesia.
The comparative effects of ketorolac, dezocine, and fentanyl were evaluated in 136 healthy female patients undergoing outpatient laparoscopic procedures according to a randomized, double-blind protocol. Patients received ketorolac (60 mg) or dezocine (6 mg) or fentanyl (100 micrograms, control group) before the start of the operation. A standardized general anesthetic technique consisting of midazolam (2 mg), fentanyl (50 micrograms), and propofol (2 mg/kg) for induction of anesthesia followed by propofol (120 micrograms.kg-1.min-1), vecuronium (1-2 mg), and 67% nitrous oxide in oxygen for maintenance of anesthesia, was used. ⋯ However, 52% of the patients receiving dezocine required antinausea therapy in the postanesthesia care unit, compared with 20% and 18% in the fentanyl and ketorolac groups, respectively. Finally, recovery times were significantly shorter in the ketorolac (vs dezocine) group. Although both ketorolac and dezocine were effective alternatives to fentanyl when administered during outpatient laparoscopy, dezocine was associated with an increased incidence of postoperative nausea and a delayed discharge time compared with ketorolac.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of ketorolac and morphine for postoperative pain after major surgery.
This study was designed to determine the relative analgesic efficacy and safety of single intramuscular injections of ketorolac (10 mg or 30 mg) and morphine (10 mg) in patients of either sex with moderate to severe pain after major surgery. In a single-dose, randomised, double-blind study of parallel design, pain was assessed immediately before injection of test medication and at regular intervals for 8 h thereafter. One hundred and seventeen patients (109 undergoing cardiac surgery; 8 lung surgery) were randomized to one of the three treatment groups. ⋯ The results of this study show that ketorolac is an effective and safe (with regard to arterial pressure, blood gases and lung function) analgesic for relief of postoperative pain after major surgery in stable patients. No clinically significant adverse effects occurred during the study. One cannot exclude an influence on patients with organ system dysfunction or on parameters not measured in this study.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of intravenous ketorolac with morphine for postoperative pain in children.
Ninety-two children from 3 to 12 years of age were given intravenous morphine or ketorolac by titration, or ketorolac by bolus injection for moderate or severe postsurgical pain in a double-blind randomized parallel-group study. Pain scores were assessed every 5 minutes until pain relief was complete, and then every 15 minutes for 8 hours or until pain returned. Twenty-nine of 30 patients receiving morphine and 25 of 30 patients in each group receiving ketorolac achieved pain relief. ⋯ Median durations of analgesia from initial drug administration were 170, 190, and 225 minutes in the morphine, ketorolac titration, and ketorolac bolus groups, respectively. The most common side effect was injection site pain. Analgesia after intravenous ketorolac developed more slowly but was sustained better than morphine.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of the safety and efficacy of a combination analgesic Myprodol and Ponstan in the treatment of dental pain.
A comparison of the efficacy of Myprodol, a combination analgesic (Ibuprofen, Paracetamol and Codeine phosphate) and Ponstan (Mefenamic acid) was undertaken in a randomised double blind trial of 52 patients who underwent surgical removal of impacted or unerupted teeth. Pain scores were measured for patients pre- and post operatively by means of a visual analogue scale and data was analysed using the BMPD package on the ISM main frame computer at the Medical Research Council. The results indicated that although Myprodol and Ponstan were equally adequate and well tolerated in the control of post operative dental pain, Myprodol exceeded Ponstan in duration of analgesia and in the degree of pain intensity control experienced by the patient.

Randomized Controlled Trial Comparative Study Clinical Trial
Perioperative effects of oral ketorolac and acetaminophen in children undergoing bilateral myringotomy.
Prophylactic administration of analgesics before surgery can decrease the intraoperative anaesthetic requirement and decrease pain during the early postoperative period. In a double-blind, placebo-controlled study involving 90 healthy ASA physical status I or II children undergoing bilateral myringotomy, we compared the postoperative analgesic effects of oral acetaminophen and ketorolac, when administered 30 min before induction of anaesthesia. Patients were randomized to receive saline (0.1 ml.kg-1), acetaminophen (10 mg.kg-1) or ketorolac (1 mg.kg-1) diluted in cherry syrup to a total volume of 5 ml. ⋯ The ketorolac group had lower postoperative pain scores and required less frequent analgesic therapy in the early postoperative period compared with the acetaminophen and placebo groups. In contrast, there were no differences in pain scores or analgesic requirements between the acetaminophen and the placebo groups. We conclude that the preoperative administration of oral ketorolac, but not acetaminophen, provided better postoperative pain control than placebo in children undergoing bilateral myringotomy.
