We designed a randomized, double-blind study to assess the analgesic efficacy and safety of perioperative ketorolac infusion in 95 patients undergoing cholecystectomy. The ketorolac group (n = 48) received premedication, combined with ketorolac 30 mg intramuscularly (IM), followed by a ketorolac continuous infusion (2 mg/h). The control group (n = 47) received an IM bolus of NaCl 0.9% (1 mL) followed by continuous saline infusion (2 mL/h) for 24 h. Operative blood losses, postoperative pain, sedation, and on-demand morphine consumption (patient-controlled analgesia [PCA]) were measured. The effects on plasma catecholamines, cortisol, potassium, creatinine, skin bleeding time, prothrombin time (PT), and partial thromboplastin time (PTT) were also evaluated. Ketorolac improved pain scores (P < 0.05) and reduced plasma cortisol concentrations between 2 and 6 h (P < 0.05). No significant differences were observed concerning operative blood losses, glucose concentration, and renal and hemostatic functions. The ketorolac group required less morphine (not significant [NS]) than the control group and had less adverse effects (P = 0.002). Thus, perioperative ketorolac infusion improved the quality of postoperative pain relief, and had no major influence on endocrine-metabolic response and no negative influences on hemostatic and renal functions. This study suggests that preventive ketorolac administration, followed by a continuous infusion, is an easy, useful, and safe method for pain control after abdominal surgery.

Ketorolac tromethamine (Toradol [Syntex, Palo Alto]), a new commercially available nonsteroidal antiinflammatory drug (NSAID), has appropriate solubility and minimal tissue irritation, making it suitable for intramuscular injection. Previously, NSAID have only been available for oral use in the United States for the treatment of pain. Ketorolac, the most potent NSAID known, relieves pain through inhibition of arachidonic acid synthesis at the cyclooxygenase level and has no central opioid effects. The results of previous studies using parenteral ketorolac in combination with patient administered narcotics have shown a 40 percent reduction in narcotic requirements. However, ketorolac is presently only approved for intramuscular injection and oral use in the United States. In a prospective, randomized study, we compared intramuscular ketorolac in combination with patient controlled intravenous narcotic analgesia (morphine) (PCA-M) to PCA-M alone for the control of pain after extensive colonic resections. The combination of intramuscular ketorolac and PCA-M provided equal pain relief with no increased side effects when compared with narcotics alone. However, narcotic requirements of the patients were decreased by an average of 45 percent. Ketorolac and narcotics in combination provide effective postoperative pain relief and significantly decrease narcotic requirements. This combination may be particularly beneficial in the subpopulation of patients especially prone to narcotic related complications.
