The use of ketorolac was studied in patients undergoing lumbar laminectomy and those receiving lumbar fusion with or without instrumentation. Laminectomy patients in the ketorolac group used significantly less narcotic analgesic than did those in the narcotic treatment group. Ketorolac patients in both surgical categories experienced better pain control than narcotic group patients did. Laminectomy ketorolac patients experienced less sedation than did those in the narcotic group, and a similar trend was noted for fusion patients. A significant improvement in postoperative ambulation was demonstrated in the fusion ketorolac group. Postoperative total drug costs were significantly greater in both ketorolac treatment groups. A one-half day decrease in hospitalization was noted for laminectomy ketorolac patients. The overall annual financial impact of the use of ketorolac in lumbar spine patients is a net savings of $211,095.

Epidural morphine produces profound analgesia but also causes many adverse effects in a dose-dependent manner. This double-blind, randomized, prospective study evaluated the analgesic efficacy and safety of low dose (2 mg) epidural morphine in combination with 30 mg intramuscular (IM) Ketorolac, a non-steroidal anti-inflammatory drug with potent analgesic activity, in patients suffering pain after caesarean surgery. Ninety parturients who received epidural anaesthesia in the postoperative period were divided into 3 equal groups: group A received epidural morphine 2 mg plus IM placebo; group B received epidural morphine 2 mg plus IM Ketorolac 30 mg; and group C received epidural saline placebo plus IM Ketorolac 30 mg. All patients were observed for pain relief, vital signs and adverse effects for 24 hours post drug administration. Results showed that group B had statistically significant superior pain relief to that of the other 2 groups. The incidence of adverse effects was similar between those of group A and B. We concluded that the addition of Ketorolac by IM administration enhanced the analgesic effect of low dose (2 mg) epidural morphine in the relief of post-caesarean pain without potentiating its adverse effects.

Ketorolac tromethamine, a potent non-narcotic prostaglandin synthetase inhibiting analgesic was compared with pethidine for relief of moderate to severe postoperative pain. Forty-eight patients received Ketorolac 0.5 mg/kg and 52 received pethidine 1.25 mg/kg. The degree of pain prior to the administration of the drug and pain relief that followed were quantified using a vertical visual analogue scale (VAS) and monitored at hourly intervals. The safety profile was also studied by recording all adverse events noted. The mean pain (VAS) score at medication for Ketorolac was 7.04 and for pethidine 7.09. The pain relief obtained in the first four hours following administration of the drugs was similar for pethidine and Ketorolac. Although Ketorolac showed a longer sustained pain relief, time to peak analgesia after administration of this drug was slower than that after pethidine. It took 30 to 50 min for pethidine compared to 75 to 150 min for Ketorolac to achieve peak analgesia. The latter is therefore inappropriate if rapid pain relief is required. The incidence of side effects was significantly greater with pethidine (40.4%) as compared to Ketorolac (10.4%). The similar analgesic efficacy to pethidine makes Ketorolac an appropriate drug for the relief of postoperative pain especially in day surgery settings where observation following administration of the drug as in the case of pethidine can be dispensed with and patients sent home earlier because of the minimal side effects associated with its use. Caution must be exercised with the use of large doses of Ketorolac especially if the drug is used for more than 5 days to avoid serious complications like renal failure and gastrointestinal bleeding.

Intraarticular (IA) local anesthetics are often used for the management and prevention of pain after arthroscopic knee surgery. Systemic ketorolac is also useful in the management of these patients. Ketorolac, a nonsteroidal antiinflammatory drug (NSAID), alters the sensitivity of peripheral nociceptors by reducing the local concentration of allogenic chemicals which are activated by peripheral tissue injury. It is interesting to speculate that placing a NSAID at the site of injury might result in more profound pain relief. However, IA ketorolac has not been evaluated in arthroscopic patients. This study thus was designed to determine which regimen would result in the most effective analgesic benefit. The four groups evaluated received ketorolac (either via the parenteral or IA route) or saline placebo with or without IA bupivacaine, as follows: Group 1 received IA bupivacaine; Group 2, intravenous ketorolac and IA bupivacaine; Group 3, IA bupivacaine with ketorolac; and Group 4, IA ketorolac. The results of this study revealed a significant difference in analgesia from the IA administration of ketorolac. The group who received a combination of IA bupivacaine and IA ketorolac had decreased postoperative pain, a decreased need for postoperative analgesics, and an increased analgesic duration. We conclude that the use of IA ketorolac improved comfort in patients undergoing knee arthroscopy.

The charts of 258 patients undergoing tonsillectomy with or without adenoidectomy between June 1991 and June 1993 were reviewed. One hundred sixty-nine of these patients received ketorolac tromethamine during the perioperative period as a nonnarcotic alternative for postoperative pain management. The incidence of postoperative hemorrhage among patients who received ketorolac tromethamine was 10.1%, compared to 2.2% in those patients who received narcotic analgesia only. The average time to adequate oral intake and discharge was evaluated. Ketorolac appeared to moderately decrease the time to adequate oral intake. The use of ketorolac did not significantly alter the time to discharge. The increased incidence of postoperative hemorrhage in patients receiving ketorolac should be considered before this medication is used in the perioperative period. The risk/benefit ratio of ketorolac use as a postoperative analgesic may be better demonstrated in a prospective study.

Propofol, which is commonly used for outpatient anaesthesia, may evoke pain during infusion. Forty-eight patients (ASA-I-II) undergoing elective uterine dilatation and curettage received randomly in a standardised fashion: A: Propofol mixed with prilocaine; B: Propofol and lidocaine; C: Propofol with prilocaine+lidocaine (equal amounts) or D: Propofol and saline. The final ratio of propofol:local anaesthetic/saline was 9:1 in all mixtures. Pain on injection was significantly decreased in the three groups receiving propofol and local anaesthetic(s) compared to the one given propofol and saline. Propofol is required in greater amounts when mixed with lidocaine than when mixed with saline. A binding between the algesic part of the propofol molecule and the local anaesthetic agent may explain these findings. Another twenty-two comparable patients were given 30 mg of ketorolac or an equal volume of saline intramuscularly 45-60 minutes prior to propofol. Ketorolac given before propofol did not reduce pain on injection. This indicates that inhibition of the cyclooxygenase pathway of arachidonic acid metabolism does not play a major role in the reduction of this pain.

Laparoscopic sterilization is commonly performed as a day surgery procedure despite difficulties in providing adequate postoperative analgesia for all patients. We have examined the analgesic utility of intramuscular ketorolac in this setting by comparing it with intramuscular pethidine, both given after induction in a randomized, double-blind study in sixty such patients. Although the analgesic effects of the two drugs were comparable in the immediate postoperative period, ketorolac provided significantly better analgesia four hours after surgery (pain score of 2.7 v. 4.2, P = 0.006). The recovery times taken to awake, to ambulate and for discharge were all significantly shorter after ketorolac (4.6 v. 8.8 min, P = 0.01; 178 v. 260 min, P = 0.0005; 242 v. 320 min, P = 0.02), and the unplanned admission rate was also significantly less after ketorolac (7% v. 33%, P = 0.01). Ketorolac appears to be a useful supplement for analgesia after laparoscopic sterilization, providing improved analgesia as well as decreased recovery time and fewer unplanned admissions.

The relationship between the pharmacokinetic properties and the analgesic effect of ketorolac was evaluated with the pain-induced functional impairment model in the rat. Female Wistar rats were injected with uric acid in the knee of the right hind limb to produce dysfunction. Then, animals received an oral dose of 0.3, 1, 1.8, 3.2 or 5.6 mg/kg of ketorolac tromethamine and analgesic effect and blood concentration, determined by high-performance liquid chromatography, were evaluated at selected times for a period of 4 hr. Ketorolac produced a dose-dependent analgesic effect, measured as a recovery of the functionality of the injured limb, which reached its maximal effect at doses of 3.2 mg/kg or higher. When functionality index was plotted against ketorolac blood concentration, a direct relationship was observed that was well described by the sigmoidal maximal effect model. The data strongly suggest that ketorolac's analgesic effect depends on the blood concentration of the drug.

Ketorolac, ketoprofen and nefopam are often used in the treatment of postoperative pain. While nefopam is a non-narcotic, non-opioid central analgesic agent, ketorolac and ketoprofen are non-steroidal anti-inflammatory drugs, which, due to their prostaglandin-synthetase inhibiting activity, have antiplatelet effects. In this study we investigated the effect of ketorolac, ketoprofen and nefopam on platelet function by performing bleeding time and in vitro platelet aggregation in 30 healthy volunteers (10 for each treatment) before and 3 h after drug administration. Nefopam did not affect bleeding time and platelet aggregation, while ketorolac and ketoprofen significantly prolonged bleeding time without significantly inhibiting platelet aggregation in response to adenosine diphosphate. The prolongation of bleeding time observed after ketorolac and ketoprofen may have clinical relevance and suggests that nefopam could be more safely administered for the treatment of postoperative pain, especially in patients with haemostatic defects or after high bleeding risk surgery.

This study investigated the antinociceptive and anti-inflammatory effect of a topical non-steroidal anti-inflammatory drug in human thermal injury. Twelve healthy unmedicated volunteers had identical burn injuries produced on the medial side of both calves with a 49 degrees C 15 x 25 mm thermode. Ketorolac gel or placebo were randomly applied on the right or left calf 1.5 h before burn injury, immediately after burn injury and 6 and 12 h later in a double-blind trial where every subject served as his own control. Heat pain detection thresholds (HPDT), head pain tolerance (HPT), mechanical pain detection thresholds (MPDT) and the intensity of burn-induced erythema (erythema index, EI) were assessed in the area of the thermal injury, and areas of hyperalgesia to pin prick were determined outside the injury before and 3, 6 and 24 h after the burn injury. Burn injury led to a decrease in HPDT, HPT and MPDT, an increase in EI and development of mechanical hyperalgesia (P < 0.05). Ketorolac gel had no effect on any of the nociceptive or inflammatory variables studies (P > 0.2).
