Randomized Controlled Trial Comparative Study Clinical TrialEffects on biliary tract pressure in humans of intravenous ketorolac tromethamine compared with morphine and placebo.
This study compared the effect of ketorolac tromethamine with that of morphine and placebo on biliary tract pressure. Intraoperatively, 31 anesthetized patients received either ketorolac (30 mg IV, n = 16) or morphine (5 mg IV, n = 15) after a cholecystectomy or gallstone removal. Intrabiliary tract pressure was measured 5 min after dosing. ⋯ In the morphine group, there was significant increase in pressure over baseline. Postoperatively, there was no significant difference between ketorolac and placebo. We conclude that ketorolac has little or no effect on biliary tract dynamics; therefore, ketorolac may be a logical choice for analgesia in those situations in which spasm of the biliary tract is undesirable.

Randomized Controlled Trial Clinical Trial
Ketorolac for sickle cell vaso-occlusive crisis pain in the emergency department: lack of a narcotic-sparing effect.
To determine if a single dose of intramuscular ketorolac given on presentation to the emergency department has a narcotic-sparing effect in adult patients with sickle cell vaso-occlusive crisis pain. ⋯ The use of intramuscular ketorolac did not lead to a clinically significant reduction in the requirement for narcotics during the four-hour ED treatment period.

Randomized Controlled Trial Comparative Study Clinical Trial
A randomized, double-blind, comparative study of the efficacy of ketorolac tromethamine versus meperidine in the treatment of severe migraine.
To evaluate the relative efficacy of ketorolac tromethamine and meperidine hydrochloride in the emergency department treatment of severe migraine. ⋯ IM ketorolac tromethamine is less effective than meperidine in the ED treatment of severe migraine.

The efficacy of intramuscular ketorolac in combination with intravenous PCA morphine for postoperative pain relief.
To examine the efficacy of intramuscular (IM) ketorolac used in combination with intravenous (IV) patient-controlled analgesia (PCA) morphine for postoperative pain relief following intra-abdominal gynecologic surgery. ⋯ IM ketorolac significantly decreased PCA morphine requirements. The analgesic effects of the two drugs appear to be additive.

Ketorolac trometamol for postoperative analgesia after orthopaedic surgery.
We have compared the postoperative morphine requirements and analgesic efficacy of four doses of i.m. ketorolac 30 mg administered 6-hourly with placebo in a double-blind study of patients undergoing major or minor orthopaedic surgery. During the 24-h postoperative study period which began at the end of surgery, patients were prescribed i.m. morphine 10 mg as required 2-hourly and assessments were made of pain at 4 and 24 h. After major surgery, the median morphine consumption over 24 h was 10 mg in patients who received ketorolac, compared with 30 mg in those who received placebo (P = 0.008). ⋯ In the minor surgery groups, median morphine consumption was 0 mg in patients who received ketorolac, compared with 10 mg in those given placebo (ns). Visual analogue pain scores at 24 h after surgery were significantly less in patients who had received ketorolac compared with placebo (P = 0.046) and the overall assessment of pain relief was better in the ketorolac group (P = 0.0007). Mandatory administration of ketorolac appeared to be of benefit in both major and minor orthopaedic surgery, although the principal effects were reduction in requirement for supplementary morphine for major surgery and better overall analgesia for minor surgery.
