Abstract
Herpes simplex and herpes zoster are both viral infections caused by members of the herpesvirus family. The former is characterized by painful, fluid-filled blisters or sores on the skin and mucous membranes, while the latter presents as a painful rash with blisters, typically occurring in a single band or patch along one side of the body. The treatment remains a challenge since current antiviral therapy via oral administration may lead to unfavorable side effects such as headaches, nausea, and diarrhea. This study used electrospinning to develop biodegradable nanofibrous poly(lactic-co-glycolic acid) (PLGA) membranes for delivery of both acyclovir and ketorolac. The structure of the spun nanofibers was assessed via scanning electron microscopy (SEM), and the appearance of loaded acyclovir and ketorolac in the nanofibers was confirmed with Fourier-transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC). Release profiles of these drugs from the nanofibrous membranes were assessed using in vitro elution studies, high-performance liquid chromatography (HPLC) assays, and in vivo drug release patterns. The electrospun nanofibers had a size range of 283-725 nm in diameter, resembling the extracellular matrix of natural tissue and demonstrated excellent flexibility and extensibility. Notably, the drug-eluting nanofibers exhibited an extended release of high levels of acyclovir and ketorolac over a 21-day period. Thus, biodegradable drug-eluting membranes with a prolonged drug release could be a potential therapeutic approach for treating herpes infections.

Abstract
BACKGROUND Children often require pain management following surgery to avoid suffering. Effective pain management has consequences for healing time and quality of life. Ibuprofen, a frequently used non-steroidal anti-inflammatory drug (NSAID) administered to children, is used to treat pain and inflammation in the postoperative period. OBJECTIVES 1) To assess the efficacy and safety of ibuprofen (any dose) for acute postoperative pain management in children compared with placebo or other active comparators. 2) To compare ibuprofen administered at different doses, routes (e.g. oral, intravenous, etc.), or strategies (e.g. as needed versus as scheduled). SEARCH METHODS We used standard Cochrane search methods. We searched CENTRAL, MEDLINE, Embase, CINAHL and trials registries in August 2023. SELECTION CRITERIA We included randomised controlled trials (RCTs) in children aged 17 years and younger, treated for acute postoperative or postprocedural pain, that compared ibuprofen to placebo or any active comparator. We included RCTs that compared different administration routes, doses of ibuprofen and schedules. DATA COLLECTION AND ANALYSIS We adhered to standard Cochrane methods for data collection and analysis. Our primary outcomes were pain relief reported by the child, pain intensity reported by the child, adverse events, and serious adverse events. We present results using risk ratios (RR) and standardised mean differences (SMD), with the associated confidence intervals (CI). We used GRADE to assess the certainty of the evidence. MAIN RESULTS We included 43 RCTs that enroled 4265 children (3935 children included in this review). We rated the overall risk of bias at the study level as high or unclear for 37 studies that had one or several unclear or high risk of bias judgements across the domains. We judged six studies as having a low risk of bias across all domains. Ibuprofen versus placebo (35 RCTs) No studies reported pain relief reported by the child or a third party, or serious adverse events. Ibuprofen probably reduces child-reported pain intensity less than two hours postintervention compared to placebo (SMD -1.12, 95% CI -1.39 to -0.86; 3 studies, 259 children; moderate-certainty evidence). Ibuprofen may reduce child-reported pain intensity, two hours to less than 24 hours postintervention (SMD -1.01, 95% CI -1.24 to -0.78; 5 studies, 345 children; low-certainty evidence). Ibuprofen may result in little to no difference in adverse events compared to placebo (RR 0.79, 95% CI 0.51 to 1.23; 5 studies, 384 children; low-certainty evidence). Ibuprofen versus paracetamol (21 RCTs) No studies reported pain relief reported by the child or a third party, or serious adverse events. Ibuprofen likely reduces child-reported pain intensity less than two hours postintervention compared to paracetamol (SMD -0.42, 95% CI -0.82 to -0.02; 2 studies, 100 children; moderate-certainty evidence). Ibuprofen may slightly reduce child-reported pain intensity two hours to 24 hours postintervention (SMD -0.21, 95% CI -0.40 to -0.02; 6 studies, 422 children; low-certainty evidence). Ibuprofen may result in little to no difference in adverse events (0 events in each group; 1 study, 44 children; low-certainty evidence). Ibuprofen versus morphine (1 RCT) No studies reported pain relief or pain intensity reported by the child or a third party, or serious adverse events. Ibuprofen likely results in a reduction in adverse events compared to morphine (RR 0.58, 95% CI 0.40 to 0.83; risk difference (RD) -0.25, 95% CI -0.40 to -0.09; number needed to treat for an additional beneficial outcome (NNTB) 4; 1 study, 154 children; moderate-certainty evidence). Ibuprofen versus ketorolac (1 RCT) No studies reported pain relief or pain intensity reported by the child, or serious adverse events. Ibuprofen may result in a reduction in adverse events compared to ketorolac (RR 0.51, 95% CI 0.27 to 0.96; RD -0.29, 95% CI -0.53 to -0.04; NNTB 4; 1 study, 59 children; low-certainty evidence). AUTHORS' CONCLUSIONS Despite identifying 43 RCTs, we remain uncertain about the effect of ibuprofen compared to placebo or active comparators for some critical outcomes and in the comparisons between different doses, schedules and routes for ibuprofen administration. This is largely due to poor reporting on important outcomes such as serious adverse events, and poor study conduct or reporting that reduced our confidence in the results, along with small underpowered studies. Compared to placebo, ibuprofen likely results in pain reduction less than two hours postintervention, however, the efficacy might be lower at two hours to 24 hours. Compared to paracetamol, ibuprofen likely results in pain reduction up to 24 hours postintervention. We could not explore if there was a different effect in different kinds of surgeries or procedures. Ibuprofen likely results in a reduction in adverse events compared to morphine, and in little to no difference in bleeding when compared to paracetamol. We remain mostly uncertain about the safety of ibuprofen compared to other drugs.

Abstract
OBJECTIVE Anesthesia is correlated with the prognosis of cancer surgery. However, evidence from prospective studies focusing on breast cancer is currently limited. This systematic review aimed to investigate the effect of anesthesia-related interventions on oncological outcomes following breast cancer surgery in prospective studies. METHODS Literature searches were performed from inception to June. 2023 in the Pubmed, Web of Science, Embase, and ClinicalTrials databases. The main inclusion criteria comprised a minimum of one-year follow-up duration, with oncological outcomes as endpoints. Anesthesia-related interventions encompassed, but were not limited to, type of anesthesia, anesthetics, and analgesics. The risk of bias was assessed using the Cochrane Risk of Bias Tool. RESULTS A total of 9 studies were included. Anesthesia-related interventions included paravertebral nerve block (3), pectoral nerve block (1), sevoflurane (2), ketorolac (2), and infiltration of lidocaine (1). Cancer recurrence, metastasis, disease-free survival, or (and) overall survival were assessed. Among all included studies, only infiltration of lidocaine was found to prolong disease-free survival and overall survival. CONCLUSION Regional anesthesia and propofol did not improve oncological outcomes following breast cancer surgery. The anti-tumorigenic effect of ketorolac warrants future studies with larger sample sizes. Perioperative infiltration of lidocaine around the tumor may be a promising anti-tumorigenic intervention that can prolong overall survival in patients with early breast cancer.

Abstract
Purpose We investigate the efficacy and safety of butorphanol in multimodal analgesia combined with dexmedetomidine and ketorolac via patient-controlled intravenous analgesia (PCIA) after hepatobiliary surgery, as compared with sufentanil. Patients and Methods Postoperative follow-up data of hepatobiliary surgery patients in Henan Provincial People's Hospital from March 2018 to June 2021 were collected retrospectively and divided into butorphanol group (group B) or sufentanil group (group S) according to the postoperative intravenous controlled analgesia scheme. The baseline characteristics and surgical information of the two groups were matched through propensity score matching (PSM). Results A total of 3437 patients were screened, and PSM yielded 1816 patients after matching, including 908 in the butorphanol group and 908 in the sufentanil group. Compared with group S, the incidence of moderate-to-severe pain on the first postoperative day and the second postoperative day was lower in group B during rest (3.2% vs 10.9%, P<0.001; 1.2% vs 4.6%, P<0.001), and during movement (7.0% vs 18.9%, P<0.001; 2.6% vs 8.7%, P<0.001). Patients receiving butorphanol had a lower morphine consumption (50mg vs 120mg, P<0.001). The bolus attempts of an analgesic pump in group B were significantly lower than in group S (1 vs 2, P<0.001). Postoperative hospital length of stay was shortened in group B (11d vs 12d, P=0.017). The occurrence of postoperative vomiting was lower in group B (1.4% vs 3.0%, P=0.025) than in group S. However, more patients in group B experienced dizziness (0.9% vs 0.1%, P=0.019). Conclusion Compared with sufentanil, the application of butorphanol in multimodal analgesia combined with dexmedetomidine and ketorolac via PCIA ameliorated postoperative pain after hepatobiliary surgery, with reduced opioid consumption and shorter postoperative hospital length of stay.

Abstract
INTRODUCTION Urinary tract disorders are one of the most common pathologies in children, regardless of age, and every year their prevalence is growing. Our study is dedicated to improvement of postoperative pain management after pediatric urologic procedures and to implementation of modern approaches for enhanced recovery. AIM To develop optimal methods of postoperative pain relief for moderate and severe intensity of pain syndrome in children undergoing urological procedures. MATERIALS AND METHODS The study involved 34 patients who were undergone to urological procedures. For an objective assessment of the quality of anesthesia, the following research methods were used: clinical study with the determination of the pain intensity on a visual analogue scale (VAS) and the determination of systolic and diastolic blood pressure, pulse oximetry and echocardiographic study. RESULTS The analysis of the postoperative period with monitoring of blood pressure, oxygen saturation, pulse oximetry, subjective assessment of the pain intensity on the VAS and the echocardiographic study showed that the relative stability of the condition was associated with an adequate pain relief. The use of a combination of infulgan, which caused an early analgesic effect, with tramadol realizing its action later, provides a prolongation of analgesia. A combination of tramadol with infulgan was several times more efficient than ketorolac. CONCLUSIONS The use of a combined analgesia after urological procedures, including ketorolac, provides a hemodynamically stability in the entire postoperative period.

Abstract
Background: The eye is a highly protected organ from ocularly administered drugs; drug- and formulation-related factors contribute significantly to ocular bioavailability. There has been a growing interest in using nonsteroidal anti-inflammatory drugs in ophthalmology for treating postoperative pain, inflammation, and seasonal allergic conjunctivitis. A preformulation-assisted design boosts efficacy and reduces dose requirements. Methods: This work aims to study the preformulation characteristics of ketorolac tromethamine to improve ocular performance and future formulation development through developing an high-performance liquid chromatography (HPLC) stability-indicating assay, forced degradation under stress conditions, solubility, as well as partition and distribution coefficient measurements. An isocratic HPLC with diode array detector method was developed and validated. Accelerated degradation under different stressors (acid, alkali, heat, and oxidative) was studied. In addition, solubility, partition, and distribution were investigated at different pHs of 3.5-7.4. Results: The results indicated that the developed HPLC method was simple, rapid (retention time ≃3 min), sensitive, selective, robust, and stability indicating. The drug seems more chemically sensitive to acid degradation (∼30% and 40% of the drug was degraded under 0.1 M and 1 M HCl at 60°C for 24 h, respectively). Another significant degradation was recorded in the following order: Oxidative > alkali > heat (phosphate-buffered saline) > heat (distilled water). Being a weak ionizable drug, both water and lipid solubility, as measured through partition coefficients, it demonstrated pH-dependency. Conclusion: For the optimum balance of water and lipid solubility required for penetration through the lipophilic corneal epithelial barrier, ketorolac eye drops would be better formulated between pH 5.5 and 6.6 than being formulated at the physiological fluid pH 7.4, where the drug is extremely hydrophilic and less permeable.

Abstract
Ketorolac, a highly persistent NSAID of environmental concern, was significantly removed from water (80% removal) through photoelectrocatalysis where titanium dioxide nanotubes prepared by Ti foil electrochemical anodization at 30 V were used as photoanodes. Fifteen milligrams per liter of ketorolac solutions in a 0.05 M Na2SO4 aqueous medium was subjected to irradiation from a 365-nm light with an intensity of 1 mWcm-2 and under an applied potential of 1.3 V (vs. Hg/Hg2SO4/sat.K2SO4) at pH 6.0. When each process (photo and electrocatalysis) was carried out separately, less than 20% drug removal was achieved as monitored through UV-vis spectrophotometry. Through scavenging experiments, direct oxidation on the photogenerated holes and oxidation by hydroxyl radical formation were found to play a key role on ketorolac's degradation. Chemical oxygen demand (COD) analyses also showed a significant COD decreased (68%) since the initial COD value was 31.3 mg O2/L and the final COD value was 10.1 mg O2/L. A 48% mineralization was also achieved, as shown by total organic carbon (TOC) analyses. These results showed that electrodes based on titania nanotubes are a promising alternative material for simultaneous photocatalytic and electrocatalytic processes in water remediation.

PROCEDURES Data were collected retrospectively from the medical records of 204 dogs prescribed ophthalmic NSAIDs (diclofenac, ketorolac, or flurbiprofen), which were subdivided based on if they received any concurrent systemic NSAIDs or glucocorticoids, 136 dogs receiving a systemic NSAID (carprofen or meloxicam) alone, and 151 dogs receiving a systemic glucocorticoid (prednisone) alone at a referral hospital from 2015 to 2019. RESULTS Gastrointestinal bleeds developed in 8/79 (10.1%) of topical NSAID-only cases, 10/136 (7.4%) of systemic NSAID controls, and 14/151 (9.3%) of systemic glucocorticoid controls, with no significant difference between the three groups (p = .6103). There were no significant differences in GI bleed rates between cases treated with ketorolac, diclofenac, or flurbiprofen (p = .160), although severe GI bleeding was only seen in ketorolac-treated dogs. Presence of a known concurrent risk factor for GI bleeding was significantly associated with the development of GI bleed in dogs on ophthalmic NSAIDs (p = .032). CONCLUSIONS Dogs treated with ophthalmic NSAIDs developed GI bleeding at a frequency comparable to dogs receiving systemic NSAIDs or systemic glucocorticoids alone, suggesting that dogs receiving ophthalmic NSAIDs may be at increased risk of GI bleeding.

Abstract
BACKGROUND Peripheral regional anaesthesia is frequently used for upper extremity surgery. To prolong the duration of analgesia, adjuvants can be added to single-injection local anaesthetics. Despite attempts to compare several adjuvants in pairwise meta-analyses, a comprehensive comparison is still missing. OBJECTIVE The objective of this network meta-analysis was to determine the effectiveness of adjuvants in upper extremity peripheral nerve blocks. DESIGN A systematic review of randomised controlled trials with network meta-analyses. DATA SOURCES A literature search in Embase, CENTRAL, MEDLINE and Web of Science was performed up to March 2023. ELIGIBILITY CRITERIA Randomised trials comparing different adjuvants injected perineurally in peripheral upper extremity nerve blocks were eligible. Frequentist network meta-analysis was conducted using a random effects model with physiological saline as the comparator. The primary endpoint was the ratio of means (ROM) of the duration of analgesia. RESULTS The review included 242 randomised controlled trials with a total of 17 391 patients. Twenty-eight adjuvants were compared in the largest networks. Most network estimations consisted of a high proportion of direct evidence. Fourteen adjuvants increased the duration of analgesia significantly by the following factors, ROM [95% confidence interval (CI)]: dexamethasone 1.95 (1.79 to 2.13), buprenorphine 1.83 (1.51 to 2.24), butorphanol 1.84 (1.41 to 2.39), potassium chloride 1.89 (1.15 to 3.11), dexmedetomidine 1.70 (1.59 to 1.81), sufentanil 1.70 (1.27 to 2.29), ketorolac 1.68 (1.24 to 2.27), midazolam 1.55 (1.24 to 1.94), tramadol 1.52 (1.32 to 1.75), nalbuphine 1.50 (1.30 to 1.72), morphine 1.43 (1.09 to 1.88), magnesium sulfate 1.42 (1.20 to 1.67), clonidine 1.36 (1.24 to 1.50) and fentanyl 1.23 (1.08 to 1.40). Inconsistency in network meta-analysis was substantial. Overall side effect rates were low with all adjuvants. CONCLUSION The best interventions to prolong the duration of analgesia were dexamethasone, followed by dexmedetomidine, opioids, electrolytes, ketorolac and midazolam. There are general concerns about the quality of underlying studies and the risk of publication bias. TRIAL REGISTRATION PROSPERO 2018 CRD42018115722.

Abstract
BACKGROUND Children in acute pain often receive inadequate pain relief, partly from difficulties administering injectable analgesics. A rapid-acting, intranasal (IN) analgesic may be an alternative to other parenteral routes of administration. Our review compares the efficacy, safety, and acceptability of intranasal analgesia to intravenous (IV) and intramuscular (IM) administration; and to compare different intranasal agents. METHODS We searched Cochrane Library, MEDLINE/PubMed, Embase, Web of Knowledge, Clinicaltrials.gov, Controlled-trials.com/mrcr, Clinicaltrialsregister.eu, Apps.who.int/trialsearch. We also screened reference lists of included trials and relevant systematic reviews. Studies in English from any year were included. Two authors independently assessed all studies. We included randomised trials (RCTs) of children 0-16, with moderate to severe pain; comparing intranasal analgesia to intravenous or intramuscular analgesia, or to other intranasal agents. We excluded studies of procedural sedation or analgesia. We extracted study characteristics and outcome data and assessed risk of bias with the ROB 2.0-tool. We conducted meta-analysis and narrative review, evaluating the certainty of evidence using GRADE. Outcomes included pain reduction, adverse events, acceptability, rescue medication, ease of and time to administration. RESULTS We included 12 RCTs with a total of 1163 children aged 3 to 20, most below 10 years old, with a variety of conditions. Our review shows that: - There may be little or no difference in pain relief (single dose IN vs IV fentanyl MD 4 mm, 95% CI -8 to 16 at 30 min by 100 mm VAS; multiple doses IN vs IV fentanyl MD 0, 95%CI -0.35 to 0.35 at 15 min by Hannallah score; single dose IN vs IV ketorolac MD 0.8, 95% CI -0.4 to 1.9 by Faces Pain Scale-Revised), adverse events (single dose IN vs IV fentanyl RR 3.09, 95% CI 0.34 to 28.28; multiple doses IN vs IV fentanyl RR 1.50, 95%CI 0.29 to 7.81); single dose IN vs IV ketorolac RR 0.716, 95% CI 0.23 to 2.26), or acceptability (single dose IN vs IV ketorolac RR 0.83, 95% CI 0.66 to 1.04) between intranasal and intravenous analgesia (low certainty evidence). - Intranasal diamorphine or fentanyl probably give similar pain relief to intramuscular morphine (narrative review), and are probably more acceptable (RR 1.60, 95% CI 1.42 to 1.81) and tolerated better (RR 0.061, 95% CI 0.03 to 0.13 for uncooperative/negative reaction) (moderate certainty); adverse events may be similar (narrative review) (low certainty). - Intranasal ketamine gives similar pain relief to intranasal fentanyl (SMD 0.05, 95% CI -0.20 to 0.29 at 30 min), while having a higher risk of light sedation (RR 1.74, 95% CI 1.30 to 2.35) and mild side effects (RR 2.16, 95% CI 1.72 to 2.71) (high certainty). Need for rescue analgesia is probably similar (RR 0.85, 95% CI 0.62 to 1.17) (moderate certainty), and acceptability may be similar (RR 1.15, 95% CI 0.89 to 1.48) (low certainty). CONCLUSIONS Our review suggests that intranasal analgesics are probably a good alternative to intramuscular analgesics in children with acute moderate to severe pain; and may be an alternative to intravenous administration. Intranasal ketamine gives similar pain relief to fentanyl, but causes more sedation, which should inform the choice of intranasal agent.

Abstract
OBJECTIVE To compare ketorolac with Tramadol as a preemptive analgesic in impacted third molar surgery in terms of mean pain score, mean time of first analgesic and mean total analgesic consumption postoperatively. STUDY DESIGN Experimental study. Place and Duration of the Study: Department of Oral and Maxillofacial Surgery, Islamic International Dental Hospital, (IIDH) Riphah International University, Islamabad, from March 2018 to March 2020. METHODOLOGY Ninety-four patients, aged 18-45 years with impacted third molars were divided into two groups. Preoperatively oral tramadol 50 mg was given in group A and oral ketorolac 10 mg was given in group B. Pain score was measured 3 hours postoperatively, using the visual analogue scale (VAS), the time was noted for first analgesic consumption in hours and total consumption of analgesics. RESULTS The mean postoperative pain was measured for both groups. Pain was significantly less in Group B. The mean pain score was 4.02+1.20 in group A and 3.42+1.08 in group B measured at 3 hours postoperatively (p=0.02). The mean time interval for 1st postoperative analgesic was 2.90+1.24 hours in group A and 3.61+1.02 in group B (p=0.007). The mean total analgesic consumption was 3.75+1.27 grams in Group A and 2.27+1.74 grams min Group B (p=0.006). CONCLUSION Preemptive Ketorolac has a more prolonged analgesic effect as compared to tramadol. KEY WORDS Preemptive analgesia, Tramadol, Ketorolac, Pain score, Third molar surgery.

Abstract
PURPOSE To compare postcataract surgery anti-inflammatory regimens of intracanalicular dexamethasone insert and topical bromfenac on the incidence of cystoid macular edema (CME), iritis, pain, and photophobia. SETTING Eyes of York Cataract & Laser Center, York, Pennsylvania. DESIGN Retrospective chart review. METHODS Case records of 647 consecutive patients (1001 eyes) who underwent cataract surgery and received dexamethasone intracanalicular insert 0.4 mg (Group 1; 482 eyes) or topical nonsteroidal anti-inflammatory drug (NSAID) (bromfenac 0.075% 2 times a day) for 4 weeks postoperatively (Group 2; 519 eyes) were included. Both groups received intracameral moxifloxacin and phenylephrine/ketorolac. Patients with prior CME, vitreomacular traction, combined cataract/glaucoma surgery, and medication protocols different from those examined in this study were excluded. RESULTS Compared with the dexamethasone insert group, the topical NSAID group had a significantly lower incidence of CME (0.4% [2/519] vs 3.9% [19/482], P < .001) and photophobia (1.9% [10/519] vs 4.8% [23/482], P = .012). The incidence of breakthrough iritis (3.5% [18/519] vs 5.6% [27/482], P = .104) and pain also trended lower (4.0% [21/519] vs 5.4% [26/482], P = .314) in the topical NSAID group. CONCLUSIONS Topical NSAIDs were found to be more effective in controlling CME, pain, iritis, and photophobia after cataract surgery compared with the intracanalicular dexamethasone insert in the presence of intracameral phenylephrine/ketorolac.

Abstract
OBJECTIVE To examine the use of pain medications after radical prostatectomy using a large national database. METHODS The Premier Hospital Database was queried to identify all robotic and laparoscopic radical prostatectomies from January 2015 - March 2020 with length of stay ≥1 day. "Opioid-sparing" was defined as absence of intravenous opioid use after post-operative day 0 and absence of oral opioid use throughout admission. Comparisons were made between opioid-sparing and non-opioid-sparing prostatectomy. Logistic multivariable regression was used to identify predictors of opioid-sparing prostatectomy. RESULTS A total of 62,660 patients were included, of whom 14,806 (23.6%) underwent opioid-sparing prostatectomy. Opioid-sparing prostatectomy was associated with older age (65 vs. 63 years, p<0.01), white vs. black race (76.3% vs. 73.4%, p<0.01), high-volume surgeons (75.2% vs. 70.0%, p<0.01), and use of intravenous ketorolac (62.2% vs. 48.0%, p<0.01), intravenous acetaminophen (32.5% vs. 30.1%, p<0.01), and liposomal bupivacaine (5.4% vs. 4.9%, p<0.01). On multivariable regression, ketorolac was the strongest predictor of opioid-sparing prostatectomy (odds ratio: 1.86, 95% confidence interval: 1.79 - 1.93, p<0.01), and black race was predictive of non-opioid sparing prostatectomy (odds ratio: 0.75, 95% confidence interval: 0.71 - 0.80, P<0.01). Ketorolac was not associated with increased risk of postoperative bleeding (0.3% vs. 0.3%, p=1.0) or dialysis requirement (<0.1% vs. <0.1%, p=0.91). CONCLUSION Opioid-sparing radical prostatectomy was feasible and associated with administration of each of the non-opioid pain medications assessed. Ketorolac was the strongest predictor of opioid-sparing prostatectomy and was not associated with increased risk of bleeding or dialysis.

Abstract
Periarticular and intra-articular injections are regularly used by orthopaedic surgeons both in the clinic and operative setting. These injections include the use of local anesthetics, nonsteroidal anti-inflammatories, steroidal anti-inflammatories, and other classes of pharmaceuticals. Local anesthetics can be injected alone or in conjunction with other pharmaceuticals to maximize pain control and to minimize narcotic use as part of a multimodal pain control algorithm. Use of intra-articular local anesthetics has been shown to improve postoperative pain scores and reduce intravenous and oral narcotic consumption and narcotic-related side effects, such as constipation, sedation, depression, respiratory depression, and long-term abuse potential. However, there have been reports of chondrolysis and other side effects from these injections. In general, it can be said that lidocaine is more chondrotoxic than bupivacaine and that methylprednisolone is more chondrotoxic when combined with either lidocaine or bupivacaine. Ropivacaine with steroid maybe less chondrotoxic, but this has yet to be established. It has been shown that ropivacaine with steroids may be toxic to chondrocytes as well as bovine tenocytes. In addition, it can be generalized that longer exposures, such as an indwelling, intra-articular catheter, are more chondrotoxic than shorter exposures, such as an intra-articular injection. Greater concentrations of lidocaine and bupivacaine (i.e., 1% vs 2% and 0.25% vs 0.5%, respectively) are more toxic to chondrocytes. Cellular morphine studies have resulted in conflicting reports of whether or not it is chondrotoxic. Both ketorolac and acetaminophen have been shown to decrease postoperative pain, but ketorolac also has been shown to be chondrotoxic in a human chondrocyte model. Doing the right thing for our patients' pain may be the wrong thing for their articular cartilage. Expansion of indications for these injections should be approached with caution.

Abstract
OBJECTIVE To observe the effect of Ketorolac tromethamine combined with dezocine prior administration on hemodynamics and postoperative sedation in patients undergoing laparoscopic hernia repair. METHODS 100 male patients aged 60 to 80 years old, a line to elective laparoscopic inguinal hernia repair, were randomly divided into four groups: control group (Group A) and dezocine group (Group B), ketorolac tromethamine group (Group C), ketorolac tromethamine combined with dezocine group (Group D). Patients were administrated with 0.1 mg/kg dezocine in Group B, 0.5 mg/kg ketorolac in Group C, 0.1 mg/kg dezocine, and 0.5 mg/kg ketorolac in Group D, and with an equal dose of normal saline in group A. The heart rate (HR) and mean arterial pressure (MAP) of patients in 4 groups were recorded at each time point as follows, T0 (enter the operating room), T1 (before skin resection), 10 min after pneumoperitoneum (T2), mesh placement (T3), and laryngeal mask extraction (T4). Operation time, awakening time (time from drug withdrawal to consciousness recovery), the dosage of propofol, sufentanil, remifentanil, and intraoperative vasoactive drug dosage were recorded to compare. Visual analog scale score and sedation Ramsay score were evaluated 1, 6, 12, and 24 hours after extubation. RESULTS There was no significant difference in operation time, anesthesia recovery time, sufentanil dosage, and vasoactive drugs among all groups. The amount of propofol in Group B and D was less than that in Group A and C (P < .05), and there was no difference between Group B and D, A and C (P > .05). The amount of remifentanil in Group B, C, and D was less than that in Group A (P < .05), and Group D was less than B and C (P < .05). After extubation, HR and MAP were significantly higher than before (P < .05). Compared with T0, HR and MAP increased in each group at T4, but MAP and HR in Group D increased the least (P < .05). There were significant differences between Group B, C, D, and A, MAP and HR fluctuated little during extubation (P < .05), but there was a significant difference between Group D and B, C (P < .05). Visual analog scale scores of Group B, C, and D were lower than those of A at 1, 6, and 12 hours after surgery (P < .05), and there was a significant difference between Group D, and B, C (P < .05). Ramsay scores in Group B and D were higher than those in A and C at 1 and 6 hours after the operation (P < .05). There was no difference in the incidence of adverse reactions among groups. CONCLUSION The prophylactic use of ketorolac tromethamine and dezocine before laparoscopic inguinal hernia repair can reduce hemodynamic disorder during anesthesia recovery, increase postoperative sedative and analgesic effects.

Abstract
PURPOSE Intravenous ketorolac (IVK) is an effective and safe medication to reduce postoperative pain in the setting of oculofacial surgery. This study was undertaken to determine the impact of timing of IVK administration in orbital surgery on the reduction of postoperative pain score and opioid requirement. METHODS Patients either received IVK immediately before (n = 50), during (n = 50) or after (n = 50) orbital surgery or acted as controls (n = 50). Pain scores were assessed via an analog scale immediately after surgery and on the first postoperative day. The requirements for opioid analgesics were recorded. Statistical analyses were performed via a dedicated computerized software package. RESULTS One hundred fifty patients received IVK; 50 before incision (28 males, 22 females, mean age 52.2), 50 intraoperatively (20 males, 30 females, mean age 49.8) and 50 in the immediate postoperative period (26 males, 24 females, mean age = 55.3). Additionally, 50 patients acted as controls (26 males, 24 females, mean age 54). Immediately after surgery, administration of IVK resulted in statistically significant reduction in pain score regardless of the timing of dosing as compared with control patients (prior = 2.36, intraoperative = 2.34, postoperative = 2.46 vs. control 5.44, p < 0.0001). Eleven patients (22%) in the control group required opioids, whereas, in the IVK cohorts, only 2 (4%-preoperative), 1 (2%-intraoperative), and 1 (2%-postoperative) patients needed these medications (p = 0.0039). CONCLUSIONS In the setting of orbital surgery, IVK reduced pain scores and opioid requirement, regardless of the timing of administration, as compared with patients that did not receive the medication.

Abstract
BACKGROUND Postoperative patient-controlled analgesia provides pain relief, encourages early mobilization, and results in a shortened hospital stay. Patient-controlled analgesia involves the mixing of different types of drugs. When using patient-controlled analgesia, it is important to confirm the microbiological and physicochemical stability of each drug in a mixture to guarantee that the drug is delivered to the patient in an unaltered form. OBJECTIVES To confirm the microbiological and physicochemical stability of various drug mixtures for intravenous patient-controlled analgesia. STUDY DESIGN An in vitro protocol to examine the microbiological and physicochemical stability of the most commonly used postoperative intravenous patient-controlled analgesia mixtures at our institution. SETTING In vitro laboratory study. METHODS Each mixture contained a total of 4 drugs: fentanyl 400 µg, ketorolac 30 mg, either hydromorphone 4 mg or oxycodone 10 mg, and either ramosetron 0.3 mg or ondansetron 10 mg. Each mixture was placed in a portable patient-controlled analgesia system containing 0.9% saline and stored at a constant temperature of 24°C for 96 hours. Physical properties (color, transparency, and sedimentation) were observed with the naked eye and optical microscopy. Sterility testing was performed to assess microbiological contamination in the drug mixture during the 96-hour study period. The pH of each mixture was evaluated for up to 96 hours after mixing. The concentration of each drug was evaluated by high-performance liquid chromatography every 24 hours until 96 hours after mixing. RESULTS All mixtures appeared visibly transparent, and no sediments were visible under the microscope. Bacterial or fungal growth was not observed in any of the samples after 14 days of incubation. The pH variations in all mixtures were maintained within 0.25 over the 96-hour study period. The concentration of drugs, except ketorolac, ranged from 90-110% of the initial concentration up to 96 hours after mixing. In the mixtures with a pH of 4.21-4.39, the concentration of ketorolac significantly decreased at 24 hours and 48 hours. LIMITATIONS Confirmation of the stability of drugs in vitro does not automatically ensure that the pharmacokinetics and pharmacodynamics of the drugs are not altered in vivo. CONCLUSION With the exception of ketorolac, the drugs used in the intravenous patient-controlled analgesia drug mixtures in this study were physicochemically stable up to 96 hours after mixing. The concentration of ketorolac decreased in more acidic mixtures.

Abstract
OBJECTIVE The purpose of this randomized, double-blind study was to evaluate the anesthetic efficacy of lidocaine-ketorolac administration by Inferior Alveolar Nerve Block (IANB) in patients with irreversible pulpitis. METHODS Eighty-eight adult patients received a combination of either one cartridge of '2% lidocaine with 1: 80.000 epinephrine' (Li) plus one cartridge of a mixture of 0.8 mL of the same solution and 1mL ketorolac tromethamine (KT)(30 mg/mL), or one cartridge of Li solution plus one cartridge of a mixture of the same solution and saline. Endodontic access was prepared after fifteen minutes. Anesthetic success was defined as no or mild pain [less than 54 mm on the Heft-Parker visual analog scale (HP-VAS)] during access cavity preparation and initial file insertion. Chi-square test was used for data analysis, and the level of significance was set at 0.05 (P=0.05). RESULTS Results showed that the success rates were 34.1% and 27.3% for Li-KT and Li-Saline groups, respectively, with no significant difference between the two groups (P=0.48). However, significant decrease of baseline mean VAS pain score of the participants in both groups was found during access cavity preparation or initial file insertion (P<0.05). CONCLUSION Mixed Li-KT solution did not increase the success rate of IANB injection significantly.

Abstract
A selective chitosan-based ion exchange molecular imprinted polymer (MIP) was prepared for ketorolac (KET) using the sol-gel method and glutaraldehyde as a crosslinker. The nonimprinted polymer (NIP) was prepared and used as a control, during the whole experiment. The chemical and morphological characteristics of the prepared polymers were investigated using FTIR and SEM, respectively. The prepared MIP was applied to determine the optimum operational conditions for KET extraction from dilute aqueous solutions. The adsorption step was performed at pH 5 and a contact time of 20 min, using 0.1 N HCl as an elution solvent for 30 min. The specificity of the prepared polymer was indicated by an imprinting factor of 1.45. The prepared MIP was successfully applied for selective solid phase extraction and subsequent determination of KET in spiked human plasma samples over a range of 2-20 μg/mL, with a mean % recovery of 94.62% using derivative spectroscopy.

Abstract
OBJECTIVES The aim of the present double-blind, randomized, controlled clinical trial was to evaluate the effect of ketorolac buccal infiltration of on postendodontic pain of patients with symptomatic irreversible pulpitis in mandibular first/second molars. METHOD AND MATERIALS Sixty patients meeting the inclusion criteria were evaluated. After receiving a standard inferior alveolar nerve block (IANB) followed by a buccal infiltration injection with lidocaine, half of the participants randomly received a supplemental buccal infiltration of 30 mg/mL ketorolac tromethamine and the other half received a buccal infiltration of normal saline adjacent to the periapical region of the tooth being treated. Afterwards, all participants received a single-visit root canal treatment. Pre- and postoperative (immediately after treatment, and at 2, 4, 6, and 24 hours) pain levels were evaluated via Heft-Parker visual analog scale (HP-VAS). Analgesic consumption was also recorded. The data were statistically analyzed using repeated-measures ANOVA and Friedman tests. The significance level was set at P < .05. RESULTS There was a significant difference in postoperative pain between the two groups in overall evaluations and in each time interval (P < .001 and P = .043 respectively). Of those patients receiving ketorolac, 60% (18/30) did not require any analgesic consumption up to 24 hours postoperatively, whereas this number was 43% (13/30) for the placebo group. CONCLUSION Ketorolac buccal infiltration could reduce the postoperative pain experienced by patients requiring endodontic treatment diagnosed with symptomatic irreversible pulpitis.

Abstract
Ketorolac is a new non-steroidal anti-inflammatory drug (NSAID) having a potent nonopioid analgesic activity. Administered by continuous subcutaneous infusion (CSI), its analgesic efficacy has been documented in the treatment of somatic and visceral cancer pain whilst it has been shown to be ineffective in the treatment of neuropathic pain. Here is a description of a cancer patient with neuropathic pain unresponsive to anticonvulsant or antidepressant drugs administered in association or not with oral opioids but who was successfully treated with ketorolac alone via CSI. Furthermore, the analgesia lasted over 75 days of treatment without any significant renal and gastric side effects.

Abstract
Carotid artery surgery (CAS) performed under cervical plexus block is frequently associated with significant intra- and postoperative pain. To evaluate whether preoperative administration of ketorolac may improve analgesia in this type of surgery, 80 patients scheduled for CAS under cervical plexus block were randomly allocated to receive intravenously either 30 mg of ketorolac or placebo 30 minutes before surgery. Verbal rating scale pain scores during surgery and 3 and 6 hours after surgery, the number of patients requiring additional analgesia, and the total analgesic consumption both during and within 6 hours after surgery were significantly lower, whereas the time to first postoperative analgesia was significantly shorter in the ketorolac group than in the control group. The results of this prospective, randomized, double-blind study show that a single 30 mg dose of ketorolac administered intravenously 30 minutes before surgery reduces intraoperative pain and preempts postoperative pain in patients undergoing CAS under carotid plexus block.

Abstract
BACKGROUND AND OBJECTIVES This prospective randomized controlled trial investigated the clinical efficacy of stimulating catheters for continuous femoral nerve block in patients who underwent anterior cruciate ligament reconstruction. METHODS Seventy patients were randomized to either a stimulating catheter (SC, n = 35) or a nonstimulating catheter (NSC, n = 35) for femoral nerve block using 25 mL ropivacaine 7.5 mg/mL and clonidine 50 microg injected through the catheter. A single-injection sciatic block was also given to ensure surgical anesthesia. The time to loss of sensation to cold and pinprick of the femoral nerve was registered as the onset time. Data were registered intra- and postoperatively regarding pain scores, adverse effects, and need for supplemental anesthesia and analgesia other than a continuous postoperative infusion of ropivacaine 2 mg/mL through the continuous femoral nerve catheter set at 7 mL/h. RESULTS Onset time was faster in the SC group (SC: 6.4 +/- 2.5, NSC: 8.3 +/- 2.9 min, P = .006). Visual analog scale pain scores were similar in both groups. The number of patient-controlled regional analgesia boluses (SC: 14.6 +/- 12.6, NSC: 23.2 +/- 13.6 mg ropivacaine 2 mg/mL, P = .008) as well as intravenous rescue ketorolac (SC: 34.3 +/- 35.7, NSC: 54 +/- 39.7 mg, P = .033) administered were higher in the NSC group. CONCLUSION Although the use of a stimulating catheter was associated with faster onset time for the femoral nerve block and lower additional analgesics postoperatively, the clinical superiority (analgesia; lateral femoral cutaneous, and obturator nerve block) of stimulating catheters was not evident in this clinical setting.

Abstract
PURPOSE We evaluated whether clonidine, when added to bupivacaine, would significantly prolong caudal analgesia and decrease opioid requirements in children undergoing ureteroneocystostomy. MATERIALS AND METHODS A total of 35 children 1 to 10 years old undergoing ureteroneocystostomy received a standardized regimen of general anesthesia, and were randomized to receive a preincision caudal block consisting of either 1 ml/kg 0.125% bupivacaine (controls) or 1 ml/kg 0.125% bupivacaine with 1 microg/kg clonidine (treatment group). Caudal solutions also contained 1:400,000 epinephrine. Following the surgical procedure a second caudal block was performed with half of the original dose of medications. Caregivers were blinded to which caudal solution was administered. Postoperative outcome measures included pain scores, morphine requirements, duration of caudal analgesia and sedation scores. Statistical analysis was performed using ANOVA. RESULTS The 2 study groups were similar for mean age, weight and length of surgical procedure. Two patients in the control group were excluded because of protocol violation. Intravenous morphine requirements for rescue therapy were 0.02 mg/kg in the postanesthesia care unit and 0.1 mg/kg on postoperative day 1 for the treatment group, compared to 0.05 mg/kg and 0.2 mg/kg, respectively, for controls (p <0.05). Mean interval from anesthesia finish time to first administered dose of morphine was 8.0 hours for the treatment group and 3.9 hours for controls (p = 0.01). Five of 18 patients in the clonidine-bupivacaine group received no postoperative morphine, compared to 1 of 15 in the bupivacaine group. No patient had development of hemodynamic instability, respiratory depression or sedation requiring treatment. CONCLUSIONS The addition of clonidine to bupivacaine significantly increases the duration of caudal analgesia and decreases postoperative morphine requirements in children undergoing ureteroneocystostomy.

Abstract
UNLABELLED Anterior cruciate ligament reconstruction (ACLR) is associated with moderate to severe postoperative pain. We compared the intraarticular analgesic effects of ropivacaine and morphine with or without ketorolac and the need for rescue IV morphine at rest and during movement in patients undergoing anterior cruciate ligament reconstruction during spinal anesthesia. Thirty-nine patients receiving intraarticular patient-controlled regional analgesia with a 10-mL bolus and a 60-min lockout interval were randomized into 3 groups: the RM group received 0.25% ropivacaine and morphine 0.2 mg/mL; the RMK group received 0.25% ropivacaine, morphine 0.2 mg/mL and ketorolac 1 mg/mL; the P group received saline. Analgesic mixtures were prepared in 100-mL bags and coded. If needed, rescue morphine 2 mg was self-administered IV with 10-min lockout intervals. Pain scores and patient satisfaction were assessed at rest and during movement. There were no significant differences among the groups in pain scores and patient satisfaction. Daily morphine consumption was significantly smaller in the RMK group (8 +/- 8 mg) compared with the RM group (23 +/- 20 mg; P = 0.002) and in both groups compared with control (46 +/- 21 mg; P < 0.001). We conclude that intraarticular patient-controlled regional analgesia provides effective pain relief after anterior cruciate ligament reconstruction. The combination of intraarticular ropivacaine, morphine, and ketorolac was superior to control or to a combination of ropivacaine and morphine. IMPLICATIONS This study showed the feasibility and efficacy of intraarticular patient-controlled regional analgesia technique for pain relief after anterior cruciate ligament reconstruction. The combination of intraarticular ropivacaine, morphine, and ketorolac was superior to control or to a combination of ropivacaine and morphine.

Abstract
BACKGROUND The aim of this study was to investigate the effects of tramadol administered with ketorolac on the Bispectral Index (BIS) during anaesthesia with sevoflurane and remifentanil. METHODS Forty-six adult patients, ASA I-III, scheduled for elective minor surgical procedures were studied. Patients were premedicated with remifentanil infusion 0.4 microg kg(-1) min(-1) and anaesthesia was induced 4-5 min later with propofol 1.5 mg kg(-1) and maintained with air-oxygen (FI(O(2)) 0.4), remifentanil 0.1-0.15 microg kg(-1) min(-1) and sevoflurane, adjusted to keep the BIS between 40 and 50. After 20 min of stable anaesthesia, the subjects were allocated randomly to receive i.v. tramadol 1.5 mg kg(-1) and i.v. ketorolac 0.3 mg kg(-1) (tramadol group) or saline (control group). BIS values, mean arterial pressure, heart rate and end-tidal carbon dioxide were recorded every 5 min for 20 min. RESULTS Mean BIS values after tramadol administration were not significantly different from those recorded in patients receiving saline throughout the period of observation. There were no patients who presented explicit recall of events under anaesthesia. No significant changes in mean arterial pressure, heart rate and end-tidal carbon dioxide were noted after tramadol injection. CONCLUSION Tramadol, given with ketorolac to prevent postoperative pain, during anaesthesia maintained with sevoflurane and remifentanil at BIS between 40 and 50, does not modify the BIS value.

Abstract
UNLABELLED Intravenous regional anesthesia (IVRA) using a forearm tourniquet may be a potentially safer technique compared with using an upper arm tourniquet. Ketorolac is a useful adjuvant to lidocaine for IVRA. In this study, we assessed the analgesic efficacy of administering IVRA lidocaine and ketorolac with either a forearm or upper arm tourniquet for outpatient hand surgery. Upper arm IVRA was established using 40 mL of a solution containing 200 mg of lidocaine and ketorolac 20 mg (0.5 mg/mL). Forearm IVRA was established using 20 mL of a solution containing 100 mg of lidocaine and ketorolac 10 mg (0.5 mg/mL). Onset and duration of sensory block as well as postoperative pain and analgesic use were recorded. The patients who received forearm IVRA had a significantly longer period during which they required no analgesics (701 +/- 133 min) compared with 624 +/- 80 min for the upper arm IVRA ketorolac patients (P = 0.032). Onset of sensory block was similar between the two groups; however, recovery of sensation was significantly longer in the Forearm IVRA (22 +/- 5 min) group compared with the Upper Arm IVRA (13 +/- 3 min) group (P < 0.05). There were no differences in postoperative analgesic use or pain scores between the two groups. We conclude that forearm IVRA with lidocaine and ketorolac provides safe and effective perioperative analgesia for patients undergoing ambulatory hand surgery. This technique results in a longer duration of sensory block and prolonged postoperative analgesia compared with upper arm IVRA while using one-half the doses of both lidocaine and ketorolac. IMPLICATIONS Forearm tourniquet intravenous regional anesthesia (IVRA) with 50% less lidocaine and ketorolac provides for both a longer duration of sensory block and prolonged postoperative analgesia compared with upper arm IVRA.

Abstract
To determine the stereospecific pharmacokinetics and gastrointestinal permeability (GI) changes (surrogate measures of toxicity) in the rat following oral administration of S, R, and racemic ketorolac (KT), optically pure enantiomers (S and R 2.5 mg/kg), and racemic KT (5 mg/kg) were administered orally to male Sprague-Dawley rats and plasma samples were collected for 6 h post-dose for pharmacokinetic assessments. KT-induced changes in GI permeability were assessed using sucrose and 51Cr-EDTA as markers of gastroduodenal and distal intestinal permeability, respectively. After the racemate, R-KT was predominant in plasma (AUC S/R, 0.45). No significant differences in pharmacokinetic indices were evident following administration of the racemate as compared with individual enantiomers. In plasma, there was only negligible S-KT after administration of R-KT. After S-KT, on the other hand, AUC of R-KT was found to be 6.7% of that of S-KT. Both permeability markers showed considerable interanimal variability. Gastroduodenal permeability was significantly increased from baseline by the racemate but not by either of the two enantiomers administered alone. Permeability to 51Cr-EDTA was not significantly increased above baseline for any of the treatments. The plasma concentration of R-KT found after administration of S-KT may be from the < 2% chiral impurity which appears magnified due to its slower clearance as compared with its antipode. There is no evidence of a pharmacokinetic interaction between the enantiomers. Since 2.5 mg/kg S-KT is somewhat less toxic on the gastroduodenum than 5 mg/kg racemate, it may be a safer alternative to the latter, at least in the rat model.

Abstract
OBJECTIVE To compare the analgesic efficacy of tramadol to that of ketorolac trometamol administered intravenously and at fixed times over the 24 hours after abdominal hysterectomy. PATIENTS AND METHODS This controlled, double blind, randomized clinical trial enrolled 76 women undergoing abdominal hysterectomies. Two treatment groups were formed: the TRA (Tramadol) group received 100 mg and the KET (Ketorolac) group 30 mg administered every 6 hours intravenously. Patients were ASA I-II and aged 35 to 65 years old. Patients were excluded from the study if hysterectomy was performed because of a tumor, or if there was a history of bleeding dyscrasias, of gastric or duodenal ulcers or of allergy to drugs in the study or if other analgesics had been used within 15 days of surgery. Analgesic efficacy was assessed using a visual analog scale (VAS) and a verbal response scale (VRS). Need for top-up analgesia was recorded, as were the number of patients withdrawing before the end of the study and the side effects attributable to treatment. RESULTS The mean VAS score throughout the study was 3.6 for the TRA group and 4.4 for the KET group (non-significant, p = 0.05). Likewise, VRS scores were similar. In the first 12 h after surgery, VAS scores in the TRA group were statistically lower than those of the KET group (p < 0.05). Nine patients abandoned the study before it ended: 3 in group TRA and 1 in the KET group. Three withdrew in the TRA group (2 because of vomiting and 1 for administrative reasons). Six left the KET group (4 for uncontrolled pain, 1 for impossible intubation and 1 for administrative reasons. In the TRA group, 38% experienced vomiting whereas only 8% did so in the KET group. No serious postoperative complications were recorded. CONCLUSIONS During the first 12 hours following surgery, a 100 mg dose of tramadol has been shown to provide more effective pain relief than 30 mg of ketorolac administered intravenously every 6 hours. The only drawback to administering the drug intravenously was the high incidence of postoperative vomiting.

Abstract
OBJECTIVE To evaluate whether ketorolac ophthalmic drops prescribed four times a day can be associated with improved visual acuity and prompt resolution of edema for patients with pseudophakic cystoid macular edema identified more than 24 months after cataract surgery. DESIGN Prospective, nonrandomized, comparative (subject self-controlled) trial. PARTICIPANTS The records of nine patients who had pseudophakic cystoid macular edema more than 24 months after cataract surgery at the time treatment commenced were identified at the Wilmer Retinal Vascular Center from September 1, 1996, through March 1, 1997. MAIN OUTCOME MEASURES Best-corrected visual acuities measured on a retroilluminated Bailey-Lovie chart approximately every 3 months, contact lens biomicroscopy, and fluorescein angiography following ketorolac. INTERVENTION Commercially available ketorolac ophthalmic drops 0.5% were prescribed for the affected eye four times a day for at least 3 months and continued until edema resolved. RESULTS Ten eyes of nine patients were identified more than 24 months after cataract extraction (median, 59 months). Seven eyes (70%) improved (mean, +3.2 lines; range, +1 to +13 lines), including six by 2 or more lines 3 months after treatment initiation. Two eyes (20%) were unchanged, and one eye (10%) was 1 line worse. All seven eyes that improved 1 line or more had some or complete angiographic resolution of fluorescein dye leakage. In these seven eyes, ketorolac was discontinued when dye leakage completely resolved or failed to continue to improve on periodic 3-month follow-up examinations. In all seven eyes, recurrence of edema was noted within 3 months after ketorolac was stopped. CONCLUSIONS Chronic pseudophakic cystoid macular edema identified more than 24 months after cataract surgery can improve with topical ketorolac but probably requires persistent use.

Abstract
The possible role of spinal prostanoids in the tactile allodynia and thermal hyperalgesia associated with an experimental model of neuropathic pain was investigated. Neuropathic pain was induced by tight ligation of the L5 and L6 spinal nerves. Tactile allodynia was assessed 7 days after the surgery by measuring hindpaw withdrawal threshold to probing with von Frey filaments. Thermal hyperalgesia and nociception were determined by the 52 degrees C warm-water tail-flick test and by applying radiant heat to the plantar aspect of the hindpaw ipsilateral to the ligation. Minimal antiallodynic effect was produced by intrathecal (i.th.) administration of ketorolac or morphine up to the highest testable dose (100 microg) or by the (R)- or (S)-enantiomers of ketorolac (up to 6 microg) when administered alone. However, i.th. administration of a fixed ratio (1:1) of morphine plus racemic ketorolac or of morphine plus the (S)-enantiomer of ketorolac (S-ketorolac) produced a dose- and time-related antiallodynic effect: ED50 114 +/- 35.9 microg (total dose) for morphine plus ketorolac and 70.5 +/- 21.0 microg (total dose) for morphine plus S-ketorolac. The combination of i.th. morphine plus the (R)-enantiomer of ketorolac (R-ketorolac) (up to 200 microg total dose) was without effect. Similar antiallodynic activity was obtained for the co-administration of i.th. morphine and intravenous (i.v.) racemic ketorolac. In order to investigate the role of cyclooxygenase (COX) isozymes, relatively selective COX1 (piroxicam) and COX2 N-[2-cyclohexyloxy-4-nitrophenyl] metanesulfonamide (NS-398) inhibitors were administered i.th. (60 microg) alone or together with i.th. morphine. Piroxicam, NS-398, morphine and vehicle (90% DMSO) were without significant antiallodynic effect when administered alone, but moderate antiallodynic effects were produced by i.th. administration of fixed ratio (1:1) combinations of morphine with 60 microg each (highest soluble dose) of piroxicam (%MPE = 40.8 +/- 10.2) or NS-398 (%MPE = 32.4 +/- 9.5). Further, the combined i.th. administration of morphine, piroxicam and NS-398 in fixed 1:1:1 ratio (60 microg each) resulted in a supraadditive antiallodynic effect (%MPE = 70.4 +/- 10.8). Finally, morphine, but not ketorolac, given i.th. produced dose-dependent anti nociception in either the tail-flick or the paw-flick tests. However, there was no synergy between morphine and ketorolac against thermal nociception in either of the tests. These findings suggest that spinal prostanoids produced via both COX1 and COX2 pathways may play a role in neuropathic pain states and suggest the clinical utility of opioid plus COX-inhibitor combination therapy.

Abstract
BACKGROUND Ketorolac is a parenteral, nonsteroidal analgesic that does not have a narcotic's risks of respiratory depression, hypotension, or dependence. Its usefulness in providing pain relief in pediatric patients with acute vaso-occlusive crisis of sickle cell disease has not been studied to date. METHODS Twenty-nine patients with sickle cell disease between the ages of 5 and 18 years who presented to The Children's Hospital of Alabama emergency department (ED) with 41 distinct episodes of acute vaso-occlusive pain crisis were enrolled prospectively and randomized to receive either 0.9 mg/kg intravenous (IV) ketorolac or placebo in a double-blind fashion. All patients also received IV fluids and an initial 0.1 mg/kg of IV morphine. Subsequent standardized doses of morphine were given every 2 hours over a 6-hour observation period based upon severity of pain as scored by a 10-cm linear visual analog scale (VAS). Vital signs and pain severity were recorded initially and assessed hourly. Disposition was made at the end of the observation period. RESULTS Patients receiving ketorolac and those receiving placebo were of similar age, weight, gender, number of prior ED visits, number of prior hospital admissions, duration of pain prior to presentation, and initial pain score. The total dose of morphine received, reduction in severity of pain as measured by VAS, rate of hospital admission, and rate of return to the ED for discharged patients did not differ significantly between the two groups. CONCLUSION We were unable to demonstrate a synergistic analgesic effect for ketorolac in the treatment of pain from acute vaso-occlusive crisis in pediatric sickle cell disease. Further investigations involving larger samples of sickle cell patients may be needed to further define a role for ketorolac in the acute management of sickle cell vaso-occlusive pain.

Abstract
OBJECTIVE To compare the efficacy and safety of two analgesics (tramadol and ketorolac) for initial emergency treatment of renal colic. METHODS A prospective study on 48 patients randomly assigned to treatment with ketorolac 30 mg i.m. and tramadol 1 mg/kg s.c. Pain intensity was evaluated by a simple analogic scale ranging from 0-4 (0 = no pain, 1 = mild, 2 = moderate, 3 = severe and 4 = very severe pain). Statistical analyses were performed with Student's test and the chi square test for numerical and qualitative data, respectively. RESULTS No significant differences were found for the overall efficacy (> 80%) or side effects in both groups. However, a difference was found between both groups for pain score 15 minutes post-injection, which showed i.m. ketorolac to be more effective. CONCLUSION Both ketorolac (30 mg i.m.) and tramadol (1 mg/kg s.c.) are effective in the initial treatment of renal colic. Both drugs have an efficacy greater than 80% when used separately and almost 100% when used in combination. The analgesic effect of ketorolac is observed earlier than that of tramadol.

Abstract
The purpose of this prospective, randomized, double-blind, placebo-controlled clinical study was to determine whether the administration of intravenous ketorolac, coadministered with morphine patient-controlled analgesia (PCA), demonstrates an opioid-sparing effect, provides improved analgesia, and reduces the incidence of opioid-induced side effects in children after orthopedic surgery. The findings of enhanced analgesia with decreased opioid use suggest that coadministration of ketorolac with morphine PCA is beneficial for the treatment of pain in children after orthopedic surgery.

Abstract
1. This study examined the effects of the COX inhibitors, ketorolac and ibuprofen, and the NOS inhibitor L-NAME for their potential to both inhibit the development and reverse tolerance to the antinociceptive action of morphine. 2. Repeated administration of intrathecal morphine (15 micrograms), once daily, resulted in a progressive decline of antinociceptive effect and an increase in the ED50 value in the tailflick and paw pressure tests. Co-administration of ketorolac (30 and 45 micrograms) or S(+) ibuprofen (10 micrograms) with morphine (15 micrograms) prevented the decline of antinociceptive effect and increase in ED50 value. Similar treatment with L-NAME (100 micrograms) exerted weaker effects. Administration of S(+) but not R(-) ibuprofen (10 mg kg-1) had similar effects on systemic administration of morphine (15 mg kg-1). 3. Intrathecal or systemic administration of the COX or NOS inhibitors did not alter the baseline responses in either tests. Acute keterolac or S(+) ibuprofen also did not potentiate the acute actions of spinal or systemic morphine, but chronic intrathecal administration of these agents increased the potency of acute morphine. 4. In animals already tolerant to intrathecal morphine, subsequent administration of ketorolac (30 micrograms) with morphine (15 micrograms) partially restored the antinociceptive effect and ED50 value of acute morphine, reflecting the reversal of tolerance. Intrathecal L-NAME (100 micrograms) exerted a weaker effect. 5. These data suggest that spinal COX activity, and to a lesser extent NOS activity, contributes to the development and expression of opioid tolerance. Inhibition of COX may represent a useful approach for the prevention as well as reversal of opioid tolerance.

Abstract
Spondylolisthesis, the anterior or posterior displacement of one vertebra on another, usually affects the lumbar region. Five percent of the population has one of the five classes of spondylolisthesis, which include dysplastic, isthmic, degenerative, traumatic, and pathologic spondylolisthesis. This article focuses on the dysplastic type, which makes up 14% to 21% of all spondylolisthesis. Dysplastic spondylolisthesis usually causes no symptoms in children; pain usually begins in adolescence. The key to diagnosis is the appropriate use of radiography in the evaluation of low back pain. This report describes a case involving a 21-year-old woman presenting with back pain to the family physician. Also, it details how the diagnosis was achieved and evaluates conservative and aggressive treatment options.
