Randomized Controlled Trial Comparative Study Clinical TrialKetorolac tromethamine as compared with morphine sulfate for treatment of postoperative pain.
Ketorolac tromethamine, a nonnarcotic, prostaglandin synthesis-inhibiting analgesic, was compared with morphine sulfate for relief of moderate to severe postoperative pain. The 155 patient participants received single intramuscular doses of either ketorolac, 10, 30, or 90 mg, or morphine, 6 or 12 mg, administered in a double-blind, randomized fashion. Pain scores (verbal and visual analog) were recorded at baseline and assessed at 30 minutes and then hourly to 6 hours. ⋯ There were no serious side effects reported. The only side effect reported in more than 3% of patients was 8% somnolence with morphine. This study shows ketorolac to be a safe and effective analgesic for relief of postoperative pain.

Clinical Trial Controlled Clinical TrialPostoperative pain relief and bupivacaine plasma levels during continuous interscalene brachial plexus block.
Interscalene brachial plexus block was performed on 40 patients for prophylactic pain relief after shoulder surgery. A dose of 1.25 mg/kg of 0.5% bupivacaine was injected for the block (Group 1) and continued with an infusion of 0.25% bupivacaine 0.25 mg/kg/h (Group 2). If the postoperative analgesia was insufficient, the patients received i.m. oxycodone 0.15 mg/kg. ⋯ At 30 min, the mean bupivacaine plasma concentration was 1.0 microgram/ml in Group 1 and 0.9 microgram/ml in Group 2. The mean plasma level of bupivacaine increased from 0.7 microgram/ml after 180 min to 1.1 micrograms/ml (P less than 0.01) after 24 h of infusion, providing some evidence of accumulation during infusion. The dizziness and confusion experienced by three patients could be associated with the local anaesthetic, as they obtained relief after the infusion was stopped.
