Abstract
Therapeutic ethanol injection into primitive or secondary hepatic tumours if performed in "one shot" causes a great deal of pain. For this reason an analgesic/sedation protocol was devised. This relies on the administration of ketorolac-propofol-nitrogen oxide mixture that has been used to treat patients with neoplastic hepatic diseases. A 20 patient series is described. Analgesic protocol was very effective and the only drawbacks were a residual sleepiness than in part is probably dependent on ethanol emigration into the bloodstream and consequently to the central nervous system depression.

Abstract
One hundred and thirty-seven patients were studied to assess whether the timing of a dose of ketorolac affected cumulative morphine requirements during the first 12 post-operative hours. Pain, sedation and nausea scores, respiratory rate and degree of operative blood loss were also recorded. Thirty-six patients (group A) were given placebo injections pre- and intra-operatively. Thirty-one patients (group B) received placebo pre-operatively and ketorolac 30 mg intra-operatively. Thirty-six patients (group C) received ketorolac 10 mg pre-operatively and ketorolac 20 mg intra-operatively and thirty-four patients (group D) were given ketorolac 30 mg pre-operatively and placebo intra-operatively. Post-operative analgesia was with intravenous (i.v.) morphine administered using a patient controlled analgesia (PCA) device. Analysis of variance revealed a significant difference in morphine consumption at 1, 2, 4, 8 and 12 h postoperatively (P < 0.05) between group A (no ketorolac) and groups B, C and D (ketorolac). However, there were no significant differences between groups B, C and D during the study period. Thus, the timing of ketorolac administration made no difference to overall morphine consumption. Pain, nausea, sedation and respiratory rate scores were similar in all four groups. There was a significantly greater blood loss in patients receiving ketorolac (groups B, C and D) compared with those receiving placebo alone (group A).

Abstract
OBJECTIVE To evaluate postoperative pain relief of intramuscular ketorolac, topical bupivacaine, and placebo in patients undergoing laparoscopic tubal sterilization with silastic bands. METHODS One hundred five women undergoing laparoscopic tubal sterilization with silastic bands were randomized to one of three groups: one received intramuscular ketorolac and topical placebo applied to the fallopian tubes, the second received intramuscular placebo and topical bupivacaine, and the third received intramuscular placebo and topical placebo. Surgical procedures, anesthesia, and recovery were conducted with standardized protocols. Postoperative pain perception was graded using the modified McGill pain intensity scale at 30 minutes postoperatively, at discharge from the recovery room, and the next morning by telephone interview. Other measured variables included postoperative vomiting, additional analgesia requirement, and length of time spent in the recovery room. RESULTS Only topical bupivacaine was found to decrease postoperative pain scores significantly over those with placebo, at 30 minutes postoperatively (median score 2 compared with 4, P = .002) and at discharge from the recovery room (median score 2 compared with 3, P = .03). There was no significant decrease in pain scores with intramuscular ketorolac compared with placebo. No differences in pain scores were found between the three groups at the next morning phone call. There were no significant differences between the three groups with respect to requirements for supplemental pain medications in the recovery room, incidence of postoperative vomiting, or length of time spent in the recovery room. CONCLUSION Topical bupivacaine decreases postoperative pain scores significantly compared with placebo in women undergoing laparoscopic tubal sterilization with silastic bands.

Abstract
BACKGROUND AND OBJECTIVE Mydriatics and antiprostaglandins are routinely applied preoperatively to facilitate the aspiration of cortical material during extracapsular cataract surgery and to prevent intraoperative miosis. Unfortunately, the ideal antiprostaglandin has yet to be introduced. This study represents the first prospective, case-controlled, randomized, masked, clinical trial comparing the efficacy of oral ketorolac tromethamine (KT) with the efficacy of topical flurbiprofen sodium (FS) and a placebo (normal saline) in maintaining intraoperative mydriasis without adrenaline in the irrigation solution. PATIENTS AND METHODS Sixty-three patients, undergoing extracapsular cataract extraction with posterior chamber intraocular lens implantation, were randomly divided into three equal groups. Group 1 received 20 mg of oral KT 2 hours prior to surgery, group 2 received 0.03% FS topical solution at the recommended dosage, and group 3 received topical normal saline in a regimen identical to that of group 2. Identical mydriatics were used in both groups. The patients' pupils were measured at five stages of surgery. RESULTS The mean pupillary diameters at each surgical stage were greater in group 1 than in group 2; however, the difference was not statistically significant. The pupils in group 3 were significantly smaller than those of group 1 or group 2 (P < .05). No systemic toxicity to KT was observed. Moreover, the need for additional postoperative analgesics was significantly greater in groups 2 and 3. CONCLUSIONS Oral KT is safe, convenient, and as effective as topical FS, and has the added advantage of reducing postoperative pain.

Abstract
Analgesia with nonsteroid antiinflammatory drugs (NSAID) becomes a pressing problem today. One such drug is ketorolak tromethamine (KT), characterized by expressed analgesic activity comparable with that of opioid analgesics morphine or promedol. Our purpose was to assess KT efficacy in analgesia performed by different methods, including analgesia controlled by the patient (ACP) after surgery. In medium severe and strong pain KT was used in group I (n = 60) "as needed" in a dose of 30 mg up to 3-4 times a day, in group 2 (n = 12) by the ACP method, in group 3 (n = 16) KT was incessantly infused in a daily dose of up to 120 mg, and in group 4 (n = 11) KT was injected 3-4 times a day in a dose of 30 mg in combination with morphine ACP. The results indicate a high efficacy of KT: 83% after a single injection. Combined use of KT and promedol decreased the dose by 40-50%. Side effects were observed in 15% of patients: most often it was a sense of fever and sweating (in 4% of patients), nausea and vomiting (in 2%), insomnia (in 2%). ACP and planned injections in a daily dose of 90-120 mg is the optimal method of analgesia in patients after extensive surgical interventions.

Abstract
STUDY OBJECTIVE To compare ketorolac tromethamine with morphine for pain management after major abdominal surgery. DESIGN Double-blind, randomized study. SETTING Hospital recovery room and postoperative surgical unit. PATIENTS One hundred ninety-one patients with at least moderate pain after major abdominal surgery. INTERVENTIONS Patients received ketorolac by patient-controlled analgesia (PCA) bolus alone (Ket B), ketorolac by bolus plus infusion (Ket I), or morphine by PCA bolus (morphine), with injectable morphine available for supplementation. MEASUREMENTS AND MAIN RESULTS Levels of sedation, pain intensity, pain relief, and adverse events were recorded at baseline, at 2, 4, and 6 hours, and at termination. Supplemental morphine was required by 71% of Ket B patients, 67% of Ket I patients, and 38% of morphine patients (p < or = 0.001 for Ket B vs morphine). Although patients receiving ketorolac required more supplemental morphine than the morphine group (6.0 mg Ket I, 6.2 mg Ket B, 4.0 mg morphine), there was a large morphine-sparing effect in both ketorolac groups (total morphine 6.0 mg Ket I, 6.2 mg Ket B, 33.3 mg morphine). Overall pain relief scores were similar for morphine and Ket I groups, and were lower for Ket B than for morphine (p = 0.002). There were no differences among groups in numbers of patients with adverse events. CONCLUSION Ketorolac may be effective when administered by PCA device, and has a clear morphine-sparing effect.

Abstract
The efficacy of topical ketorolac 0.5% in treatment of vernal keratoconjunctivitis (VKC) was evaluated in a randomised double-blind prospective trial in 21 patients. Ketorolac treated eyes showed 50.7% reduction in main symptoms of itching compared to 33.3% relief in placebo treated eyes after 2 weeks of treatment (p < 0.01). Photophobia, ropy discharge, and conjunctival injection also lessened by 39.9%, 31.6%, and 39.1%, respectively, in ketorolac treated eyes compared to 23.8%, 17.3%, and 20.3% in placebo group. Transient stinging sensation was observed in 3 (14.3%) patients on ketorolac therapy. This study shows efficacy of ketorolac 0.5% solution in controlling symptoms in VKC.

Abstract
OBJECTIVE To compare the effects of topical 0.5% ketorolac tromethamine ophthalmic solution (Acular, Allergen Pharmaceuticals, Irvine, Calif) with topical 0.03% flurbiprofen sodium ophthalmic solution (Ocufen, Allergen Pharmaceuticals) on the inhibition of surgically induced miosis during phacoemulsification cataract surgery. DESIGN One hundred eighteen patients were prospectively randomized to receive 0.5% topical ketorolac or 0.03% topical flurbiprofen at 3 preoperative intervals. The flurbiprofen-treated group served as the control group. The surgeon was masked as to patient selection. Horizontal pupillary diameter measurements were obtained at the start of surgery, just before phacoemulsification, before lens implantation, and after lens implantation. RESULTS Mean horizontal pupillary diameter measurements for both medications were similar at the start of surgery. However, a consistent trend of larger pupillary diameter was seen in all subsequent surgical intervals in the ketorolac-treated group. Changes from baseline measurements also indicated a more significant inhibition of miosis at all subsequent intervals, and a more stable mydriasis throughout the procedure in the ketorolac-treated group. CONCLUSIONS Topical ketorolac is an effective inhibitor of miosis during phacoemulsification cataract surgery, and provides a more stable mydriatic effect throughout the surgical procedure.

Abstract
OBJECTIVE To evaluate the effectiveness of an ophthalmic nonsteroidal anti-inflammatory drug (NSAID) in the treatment of noninfected, non-contact lens-related, traumatic corneal abrasions and no pressure patch. DESIGN A single-center, randomized, double-masked, placebo-controlled study. PARTICIPANTS One hundred patients with noninfected, non-contact lens-related, traumatic or foreign body removal-related corneal abrasions less than 36 hours in duration. INTERVENTION All patients received a cycloplegic drop and erythromycin or polymyxin B (Polysporin Ophthalmic Ointment, Burroughs Wellcome, Research Triangle Park, NC). Patients were then randomized to receive either ketorolac tromethamine 0.5% ophthalmic solution or control vehicle drops. MAIN OUTCOME MEASURES The main outcome measures were six subjective symptoms monitored daily, evaluation of corneal abrasion, and determination of adverse events. Long-term complications were determined 3 to 8 months after randomization. RESULTS Twelve patients were excluded from the study. One day after randomization, patients receiving ketorolac tromethamine 0.5% ophthalmic solution noted significantly decreased levels of pain (P < 0.002), photophobia (P < 0.009), and foreign body sensation (P < 0.003) as compared with the control vehicle group. In addition, the time to resumption of normal activities was shorter in the group who received ketorolac tromethamine 0.5% ophthalmic solution (P < 0.001). There was no statistical difference in the amount of tearing, healing time, acuity changes, or complication rates between the two groups. CONCLUSIONS Ketorolac tromethamine 0.5% ophthalmic solution provides increased patient comfort without clinical adverse effects when used as adjunctive therapy in the treatment of noninfected, non-contact lens-related, traumatic corneal abrasions.

Abstract
The effects of mucoadhesive eye drops containing a pyrrole-acetic acid derivative (tolmetin) at 0.5% concentration on ocular inflammation produced by sodium arachidonate in the rabbit's eye were evaluated. Furthermore, the bioavailability of the mucoadhesive formulation in the aqueous humor against an aqueous-based solution was compared. Tolmetin eye drops significantly reduced the signs of ocular inflammation elicited by sodium arachidonate on conjunctiva and iris. Tolmetin treatment significantly reduced the levels of prostaglandin E2, polymorphonuclear leukocytes and protein concentration in aqueous samples obtained from the eyes treated with arachidonate. The de novo production of prostaglandin E2 by corneas obtained from rabbits sacrificed 2 hours after arachidonate instillation were significantly higher in samples taken from controls than in corneas obtained from the eyes treated with tolmetin eye drops. Furthermore, the drug treatment significantly reduced the rise in intraocular pressure arachidonate-induced. The mucoadhesive formulation showed a higher bioavailability in aqueous humor compared to the aqueous-based solution both in the uninflamed and in the inflamed rabbit eyes.

Abstract
The efficacy of postoperative pain relief by ketanov and tramal was assessed in 42 patients operated on the abdominal organs and lower limb arteries. The time of development of the analgesic effect and duration and depth of analgesia were compared. The drug effects were compared from protocols of clinical examination, hemodynamic changes, and time course of external respiration and blood saturation with oxygen. The findings confirm a high analgesic effect of ketanov, which is not inferior to tramal, and by some parameters even higher.

Abstract
This multicenter study compared the analgesic efficacy and side effects of ketorolac and hydrocodone-acetaminophen when administered orally after ambulatory arthroscopic or laparoscopic tubal ligation procedures. After awakening from general anesthesia, 252 patients experiencing moderate or severe postoperative pain were randomly assigned to receive one of three analgesic treatments according to a placebo-controlled, double-blind protocol. Group 1 (n = 83) received oral ketorolac 10 mg every 6 h for up to 3 days, Group 2 (n = 82) received hydrocodone 7.5 mg plus acetaminophen 750 mg every 6 h for up to 3 days, and Group 3 (n = 87) received placebo capsules followed by ketorolac 10 mg every 6 h for up to 3 days. Severity of pain was recorded using a 4-point categorical score and visual analog scale (VAS) at 0.5 h and subsequently at hourly intervals for 6 h, as well as daily for up to 3 days. Pain relief was recorded using a 5-point categorical scale at the same time points. In the patients undergoing arthroscopic surgery, both ketorolac and hydromorphone-acetaminophen provided superior pain relief compared with the placebo. Although the categorical summed pain intensity difference (SPID), VAS SPID, and total pain relief scores were higher in the ketorolac group compared with the hydrocodone-acetaminophen group, the differences were not statistically significant. In the patients undergoing laparoscopic tubal ligation surgery, the three treatment groups displayed similar responses to the study medications. However, the ketorolac group scored higher in terms of overall tolerability than the hydrocodone-acetaminophen group. In conclusion, there was no difference in the efficacy between oral ketorolac and hydrocodone-acetaminophen combination in controlling pain after outpatient arthroscopic surgery procedures. Neither oral analgesic proved to be very effective after laparoscopic tubal ligation.

Abstract
BACKGROUND AND OBJECTIVES This study was designed to determine whether administration of ketorolac directly in the surgical site results in enhanced analgesia. METHODS A randomized double-blind study was undertaken at a university-affiliated tertiary care hospital. Thirty outpatients undergoing unilateral inguinal hernia repair by one of two surgeons under local anesthesia with sedation were evaluated. Patients were invited to participate in this investigation at the time of the preoperative surgical visit. Patients who had a contraindication to the use of ketorolac or who refused repair under local anesthesia with sedation were excluded. Patients received ketorolac 60 mg either via the parenteral route or directly in the surgical site (mixed with the local anesthetic). The outcome measures included visual analog pain scores, measured at two different times in the hospital, pain scores at rest and with movement 24 hours after surgery, time to first analgesic, and total analgesic requirement. RESULTS The study revealed lower 24 hour movement-associated pain scores (P < .02), increased time to first analgesic (P < .03), and decreased oral analgesic consumption (P < .0002) in the surgical site group. CONCLUSIONS Ketorolac provides enhanced patient comfort when it is administered in the surgical site in patients undergoing inguinal hernia repair. It is recommended that clinicians add ketorolac to the local anesthetic solution in such patients.

Abstract
The pharmacokinetics of 2 doses of intravenous ketorolac (0.5 and 0.9 mg x kg-1) were studied in 14 children (age 2-8 years). A single dose of the drug was injected into the dorsum vein of one hand. Blood samples were collected at regular time intervals for 6 hours. Serum ketorolac concentrations were assayed using a high pressure liquid chromatography method. Pharmacokinetic values were estimated by a nonlinear computer program. The distribution volume (Vdarea), the total clearance (Cltotal), and elimination half-life (t1/2 beta) were similar in both groups of children who either received 0.5 or 0.9 mg x kg-1 of ketorolac. The estimated geometric mean Vdarea, Cltotal, and t1/2 beta ratios (95% CI in parentheses) for 0.9 mg x kg-1:0.5 mg x kg-1 were 1.24 (0.82, 1.50), 1.14 (0.88, 1.23), and 1.083 (0.40, 1.81), respectively. The pharmacokinetic parameters found in this study are different from those found by other authors in adult subjects.

Abstract
This double-blind randomized trial assessed the effect of adding an intravenous continuous infusion of ketorolac to a patient-controlled analgesia (PCA) morphine regimen on analgesia, heart rate, arterial blood pressure, and postoperative myocardial ischemia. Patients having elective total hip or knee replacement were randomized to receive ketorolac 30 mg bolus, followed by an infusion of 5 mg/h for 24 h or placebo. All patients had access to PCA morphine (20 microg/kg bolus, with a lockout of 6 min). Patients were monitored for pain visual analog scale, blood pressure, heart rate, and ST segment depression via a continuous Holter monitor. ST depression of 1 mm 60 ms after the J point was considered significant if it lasted more than 1 min. There was no difference in demographics, risk factors, or cardiac medications between the groups. Ketorolac-treated patients had significantly better pain control at 2, 6, and 24 h. There was significant morphine sparing at all times after 3 h. There was no difference in the number of ischemic events between the groups. The ischemic episodes of the patients who received ketorolac occurred at slower heart rates (97 +/- 15 vs 114 +/- 16 bpm, P = 0.001) than those of patients in the placebo group. The duration of ST depression was shorter in ketorolac-treated patients (24 +/- 35 vs 76 +/- 95 min, P < 0.05). All ST depressions were clinically silent. Logistic regression of factors predicting ischemia included the use of calcium channel blockers and low pain score. These results suggest that analgesia with ketorolac reduces the duration of ischemic episodes in the first 24 h postoperatively.

PURPOSE To assess the safety and efficacy of transdermal fentanyl plus im ketorolac vs im ketorolac alone in the treatment of postoperative pain. METHODS Ninety-two patients scheduled for surgery involving moderate to severe postoperative pain were randomized to one of two groups. Group A (n = 46) received an active fentanyl patch and group P (n = 46) received a placebo patch. Patches remained in place for 24 hr. Each patient received intraoperative ketorolac, 60 mg im. Patients were monitored for 36 hr postoperatively and the groups were analyzed for ketorolac usage, pain scores, vital signs, serum fentanyl concentrations, and adverse events. Intramuscular ketorolac was available on demand. RESULTS Group A had lower pain scores at 8.12, 16 and 24 hr after patch placement (P < 0.05). Group A had lower heart rates, lower respiratory rates and fewer dropouts due to inadequate pain relief (4.3% vs 21.7% P < 0.05). Group A patients also used less ketorolac than group P patients (P < 0.05). The incidence of pruritus was higher in group A patients (19% vs 2%, P < 0.05), while the incidence of nausea and vomiting was not different between the two groups. Transdermal fentanyl was adequate "stand-alone" analgesia in only 23.8% of group A patients while 93.7% of the remaining group A patients receiving a combination of transdermal fentanyl and ketorolac had adequate pain relief. CONCLUSION The transdermal fentanyl delivery system plus ketorolac im was more effective in controlling post-operative pain than ketorolac im alone. The two treatment modalities were comparable in safety with no difference in serious adverse events.

Abstract
BACKGROUND A randomized, double-masked study was conducted to investigate the effects of 0.5% ketorolac tromethamine (Acular) and 0.1% diclofenac sodium (Voltaren) on normal human corneal sensation. METHODS Thirty normal volunteers were divided into two groups, (1) two-drop group, and (2) multiple-drop group. In the two-drop group, 15 volunteers randomly received two drops of 0.5% ketorolac tromethamine on one eye and two drops of 0.1% diclofenac sodium on the fellow eye. A masked investigator measured corneal sensation with the Cochet-Bonnet esthesiometer before applying the drops, and at 15, 30, and 60 minutes after using the eye drops. In the multiple-drop group, another 15 volunteers were randomly administered one drop of 0.5% ketorolac tromethamine or 0.1% diclofenac sodium in each eye, and the procedure was repeated every 5 minutes for 20 minutes. Corneal sensation was measured before, and 0, 15, 30 and 60 minutes after applying the drops. RESULTS In the two-drop group, neither of the eye drops had any effect on corneal sensation when only two drops were applied. In the multiple-drop group, corneal sensation was significantly reduced after multiple drops (p < 0.05) and was subsequently effective for at least 1 hour. CONCLUSION Both 0.5% ketorolac and 0.1% diclofenac can significantly decrease corneal sensation in normal eyes when multiple drops are used.
