Neurotrophic Keratopathy after wide retinal endolaser and postoperative Ketorolac eye drops: A case series.

PURPOSE: We report a series of 5 cases, happened in a period of 5 months, who developed neurotrophic keratopathy (NK) following pars plana vitrectomy (PPV) and retinal endolaser for rhegmatogenous retinal detachment (RRD). In our several decennary experience of surgical center predominantly based on vitreoretinal surgery, we had rare cases of postoperative NK. These recent cases of post-surgical NK happened contextually to our change of postoperative non-steroidal anti-inflammatory drugs (NSAIDs) drops, based on Ketorolac Tromethamine 0.5% eye drops. CASES PRESENTATION: Five patients with a mean age of 61 ± 7.3 years were treated with one or more PPV with intraoperative peripheral endolaser for RRD. Nobody had previous herpetic keratitis, systemic disease like diabetes mellitus or other predisposing factors for NK. In the postoperative period, all patients received Ketorolac Tromethamine 0.5% eye drops for a mean period of 54 ± 25 days. During follow-up visits they developed NK and they were successfully treated with suspension of Ketorolac eye drops, application of therapeutic contact lens or amniotic membrane patch and topical lubricant therapy. CONCLUSIONS: Postoperative Ketorolac eye drops, in patients who underwent PPV with endolaser, may reduce the corneal sensitivity, predispose to epithelial disruption and NK development. Studies are needed to explore the effect of NSAIDs on corneal sensitivity reduction in patient who will undergo PPV and extensive endolaser.

Preparation of polycaprolactone and polymethacrylate nanofibers for controlled ocular delivery of ketorolac tromethamine: Pharmacokinetic study in Rabbit's Eye.

Ophthalmitis is an inflammation of the eye triggered by various conditions including diseases, allergy, trauma, or surgery. Management of this condition usually includes administration of topical anti-inflammatory eye drops such as nonsteroidal anti-inflammatory drugs. To overcome the challenges of conventional eye drops such as frequent administration and low intraocular bioavailability, nanofibrous inserts of Ketorolac tromethamine (KET) were developed in this study. Polycaprolactone and polymethacrylate containing KET were electrospun to prepare biocompatible and biodegradable nanofibers. The inserts were studied for morphology, drug-polymer interaction, physicochemical properties, cell viability, in vitro drug release study and pharmacokinetic study in rabbit's eye. Uniform nanofibers with mean diameters < 350 nm were developed. Suitable mechanical properties with tensile strength up to 2.8 MPa indicated high strength and flexibility of inserts. Nanofibers exhibited controlled drug release for up to 140 h at a concentration more than 50 µg/ml in tears without causing any damage or irritation to the eye. Formulations indicated enhanced pharmacokinetics with 6- to 8-times higher Area Under the Curve (AUC0-144) compared to KET eye drop. Acceptable cell viability confirmed the safety of inserts. Due to the fact that this preservative-free polymer insert can obtain therapeutic concentration in the tear film without fluctuation, it can be a suitable alternative for the treatment of intraocular inflammations with less complications, easier use, and even higher intraocular penetration.

The effect of topical ketorolac tromethamine on macular thickening after phacoemulsification in diabetic patients.

BACKGROUND: To determine the effect of ketorolac tromethamine 0.5% in preventing post-phacoemulsification macular thickening. This randomized clinical trial. patients randomized 1:1 to receive either topical ketorolac three times a day or a placebo. METHODS: A total of 101 eyes of 101 diabetic patients who were scheduled for phacoemulsification and had normal macular contour and thickness enrolled consecutively. The topical ketorolac and placebo were prescribed on the day before surgery and continued up to 4 weeks after surgery. Patients with proliferative diabetic retinopathy, a history of intravitreal injection in less than three months, a history of macular photocoagulation in less than 6 months, and any other concomitant ocular pathologies were excluded. Central macular thickness (CMT) and best corrected visual acuity (BCVA) was recorded in the follow-ups of 6, 12, and 24 weeks after the surgery and compared with the controls. RESULTS: 49 eyes in the case group and 52 eyes in the control group were analyzed. Mean BCVA was significantly improved in both groups at all follow-ups (P < 0.001 for all). There was no statistically significant difference regarding the BCVA in different time points except week 12 (P = 0.028) among the study group. In the case and control groups, CMT was increased at all follow-ups (P < 0.05). There was no statistically significant difference when comparing the two groups regarding the mean of CMT at any time point postoperatively (P > 0.05 for all). CONCLUSION: Based on our findings, topical ketorolac tromethamine 0.5% is not effective in the prevention of post-phacoemulsification macular thickening in diabetic patients. TRAIL REGISTRATION: The study protocol was registered into www. CLINICALTRIAL: gov with the RCT registration number NCT03551808. (2018/06/11 ) CLINICAL TRIAL REGISTRATION NUMBER: NCT03551808.

Effect of ketorolac tromethamine combined with dezocine prior administration on hemodynamics and postoperative analgesia in patients undergoing laparoscopic hernia repair.

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.

Toradol to Reduce Ureteroscopy Symptoms Trial (TRUST).

OBJECTIVE: To assess the use of intraoperative IV ketorolac (Toradol) on the peri-operative total morphine milligram equivalent (MME) requirements of patients undergoing ureteroscopy for nephrolithiasis. METHODS: Patients undergoing ambulatory ureteroscopy for nephrolithiasis were randomized to receive ketorolac at time of anesthesia induction. Patients and surgeons were blinded to treatment. Intraoperative, postoperative and combined MME were calculated. Multivariable regression was used to identify independent predictors of MME requirement. Complications were recorded. RESULTS: A total of 94 patients were analyzed following randomization. There were 46 patients in the treatment arm and 48 patients in the control arm. There were no statistically significant differences in gender, age, BMI, operative length or baseline pain medication use between groups (P >.05). Patients in the treatment arm required lower intraoperative MME when compared to the control arm (17.1 vs 24, P< .01). There were no statistically significant differences in the postoperative MME requirements between groups. The combined peri-operative MME was lower in the treatment arm compared to the control arm (22.2 vs 30.4, P< .02). Ketorolac use was an independent predictor of lower MME use on multivariable analysis (beta coefficient -5.1, P< .01). There was no statistically significant difference with regards to complication numbers between the treatment arms. CONCLUSION: Ketorolac during ureteroscopy is associated with a 37% reduction in narcotic requirement and is an independent predictor of decreased peri-operative narcotic needs. These findings show that intra-operative use of ketorolac effectively reduces narcotic requirements and should be considered independently or as part of a multimodal pain control protocol, unless otherwise contraindicated.

Intravenous Ketorolac Infusion for Intractable Pleuritic Pain Secondary to Metastatic Epithelioid Hemangioendothelioma.

Background: Epithelioid hemangioendothelioma (EHE) patients can experience severe pain. Nonsteroidal anti-inflammatory drugs, including ketorolac tromethamine, can effectively treat cancer-related pain, provide an opioid-sparing effect, and may be particularly effective for EHE pain. There are limited data describing prolonged (>5 days) continuous intravenous (IV) ketorolac infusion for cancer-related pain and no data on its use in EHE. Case Description: A 67-year-old woman with metastatic hepatic EHE suffered from chronic intractable pleuritic pain unresponsive to trials of nonopioid, opioid, adjuvant medications, and nonpharmacological interventions. In the hospital, continuous IV ketorolac infusion at 3.8 mg/hour (91.2 mg/day) effectively managed pain. With thorough monitoring, the patient was discharged on continuous IV ketorolac infusion at 3 mg/hour (72 mg/day). Infusion continued for 79 days without clinical or laboratory evidence of ketorolac toxicity. Conclusion: Ketorolac tromethamine as a long-term infusion is a potentially viable analgesic for patients with intractable EHE-related pain unresponsive to standard therapies.

DDX3 modulates cisplatin resistance in OSCC through ALKBH5-mediated m6A-demethylation of FOXM1 and NANOG.

Platinum based drugs alone or in combination with 5FU and docetaxel are common regimen chemotherapeutics for the treatment of advanced OSCC. Chemoresistance is one of the major factors of treatment failure in OSCC. Human RNA helicase DDX3 plays an important role in cell proliferation, invasion, and metastasis in several neoplasms. The potential role of DDX3 in chemoresistance is yet to be explored. Enhanced cancer stem cells (CSCs) population significantly contributes to chemoresistance and recurrence. A recent study showed that m6A RNA regulates self-renewal and tumorigenesis property in cancer. In this study we found genetic (shRNA) or pharmacological (ketorolac salt) inhibition of DDX3 reduced CSC population by suppressing the expression of FOXM1 and NANOG. We also found that m6A demethylase ALKBH5 is directly regulated by DDX3 which leads to decreased m6A methylation in FOXM1 and NANOG nascent transcript that contribute to chemoresistance. Here, we found DDX3 expression was upregulated in both cisplatin-resistant OSCC lines and chemoresistant tumors when compared with their respective sensitive counterparts. In a patient-derived cell xenograft model of chemoresistant OSCC, ketorolac salt restores cisplatin-mediated cell death and facilitates a significant reduction of tumor burdens. Our work uncovers a critical function of DDX3 and provides a new role in m6 demethylation of RNA. A combination regimen of ketorolac salt with cisplatin deserves further clinical investigation in advanced OSCC.

Multimodal opioid-sparing postoperative pain regimen compared with the standard postoperative pain regimen in vaginal pelvic reconstructive surgery: a multicenter randomized controlled trial.

BACKGROUND: Postoperative pain control after urogynecological surgery has traditionally been opioid centered with frequent narcotic administration. Few studies have addressed optimal pain control strategies for vaginal pelvic reconstructive surgery that limit opioid use. OBJECTIVE: The objective of the study was to determine whether, ice packs, Tylenol, and Toradol, a novel opioid-sparing multimodal postoperative pain regimen has improved pain control compared with the standard postoperative pain regimen in patients undergoing inpatient vaginal pelvic reconstructive surgery. STUDY DESIGN: This was a multicenter randomized controlled trial of women undergoing vaginal pelvic reconstructive surgery. Patients were randomized to the ice packs, Tylenol, and Toradol postoperative pain regimen or the standard regimen. The ice packs, Tylenol, and Toradol regimen consists of around-the-clock ice packs, around-the-clock oral acetaminophen, around-the-clock intravenous ketorolac, and intravenous hydromorphone for breakthrough pain. The standard regimen consists of as-needed ibuprofen, as-needed acetaminophen/oxycodone, and intravenous hydromorphone for breakthrough pain. The primary outcome was postoperative day 1 pain evaluated the morning after surgery using a visual analog scale. Secondary outcomes included the validated Quality of Recovery Questionnaire, satisfaction scores, inpatient narcotic consumption, outpatient pain medication consumption, and visual analog scale scores at other time intervals. In all, 27 patients in each arm were required to detect a mean difference of 25 mm on a 100 mm visual analog scale (90% power). RESULTS: Thirty patients were randomized to ice packs, Tylenol, and Toradol and 33 to the standard therapy. Patient and surgical demographics were similar. The median morning visual analog scale pain score was lower in the ice packs, Tylenol, and Toradol group (20 mm vs 40 mm, P = .03). Numerical median pain scores were lower at the 96 hour phone call in the ice packs, Tylenol, and Toradol group (2 vs 3, P = .04). Patients randomized to the ICE-T regimen received fewer narcotics (expressed in oral morphine equivalents) from the postanesthesia care unit exit to discharge (2.9 vs 20.4, P < .001) and received fewer narcotics during the entire hospitalization (55.7 vs 91.2, P < .001). At 96 hour follow up, patients in the ice packs, Tylenol, and Toradol group used 4.9 ketorolac tablets compared with 4.6 oxycodone/acetaminophen tablets in the standard group (P = .81); however, ice packs, Tylenol, and Toradol patients required more acetaminophen than ibuprofen by patients in the standard arm (10.7 vs 6.2 tablets, P = .012). There were no differences in Quality of Recovery Questionnaire or satisfaction scores either in the morning after surgery or at 96 hour follow up. CONCLUSION: The ice packs, Tylenol, and Toradol multimodal pain regimen offers improved pain control the morning after surgery and 96 hours postoperatively compared with the standard regimen with no differences in patient satisfaction and quality of recovery. Ice packs, Tylenol, and Toradol can significantly limit postoperative inpatient narcotic use and eliminate outpatient narcotic use in patients undergoing vaginal pelvic reconstructive surgery.

Evolving Treatment Patterns of NFL Players by Orthopaedic Team Physicians Over the Past Decade, 2008-2016.

BACKGROUND: Previous studies have analyzed the treatment patterns used to manage injuries in National Football League (NFL) players. HYPOTHESIS: Treatment patterns for injuries in NFL players will have changed over the study period. STUDY DESIGN: Descriptive epidemiology study. LEVEL OF EVIDENCE: Level 5. METHODS: The head orthopaedic team physicians for all 32 NFL teams were asked to complete a survey containing questions regarding experience as team physician, medical coverage of the team, and treatment preferences for some of the most common injuries occurring in football players. Responses from the current survey were compared with responses from the same survey sent to NFL team physicians in 2008. RESULTS: Responses were received from 31 (31/32, 97%) NFL team physicians in 2008 and 29 (29/32, 91%) NFL team physicians between April 2016 and May 2017. The proportion of physicians preferring patellar tendon autograft in anterior cruciate ligament (ACL) reconstruction increased from 87% in 2008 to 97% in 2016 ( P = 0.054). In 2008, 49% of physicians allowed return to contact after ACL reconstruction at 6 months or less as compared with only 14% of physicians in 2016 ( P = 0.033). In 2008, 93% of physicians used Toradol injections prior to a game to help with nagging injuries. Toradol injection utilization decreased to 48% of physicians in 2016 ( P < 0.001). Seventy-nine percent of physicians would administer 5 or more Toradol injections prior to a game in 2008, as compared with 28% of physicians in 2016 ( P < 0.0001). CONCLUSION: Orthopaedic physicians have changed their injury treatment preferences for professional football players. In particular, physicians have become more cautious with allowing players to return to play after ACL reconstruction and with the use of pregame Toradol injections. CLINICAL RELEVANCE: Expert opinions can help guide treatment decisions and lead to better care of all athletes.

Cost-effectiveness of intravenous acetaminophen and ketorolac in adolescents undergoing idiopathic scoliosis surgery.

BACKGROUND: Enhanced recovery after surgery protocols increasingly use multimodal analgesia after major surgeries with intravenous acetaminophen and ketorolac, despite no documented cost-effectiveness of these strategies. AIMS: The goal of this prospective cohort study was to model cost-effectiveness of adding acetaminophen or acetaminophen + ketorolac to opioids for postoperative outcomes in children having scoliosis surgery. METHODS: Of 106 postsurgical children, 36 received only opioids, 26 received intravenous acetaminophen, and 44 received acetaminophen + ketorolac as analgesia adjuncts. Costs were calculated in 2015 US $. Decision analytic model was constructed with Decision Maker® software. Base-case and sensitivity analyses were performed with effectiveness defined as avoidance of opioid adverse effects. RESULTS: The groups were comparable demographically. Compared with opioids-only strategy, subjects in the intravenous acetaminophen + ketorolac strategy consumed less opioids (P = .002; difference in mean morphine consumption on postoperative days 1 and 2 was -0.44 mg/kg (95% CI -0.72 to -0.16); tolerated meals earlier (P < .001; RR 0.250 (0.112-0.556)) and had less constipation (P < .001; RR 0.226 (0.094-0.546)). Base-case analysis showed that of the 3 strategies, use of opioids alone is both most costly and least effective, opioids + intravenous acetaminophen is intermediate in both cost and effectiveness; and opioids + intravenous acetaminophen and ketorolac is the least expensive and most effective strategy. The addition of intravenous acetaminophen with or without ketorolac to an opioid-only strategy saves $510-$947 per patient undergoing spine surgery and decreases opioid side effects. CONCLUSION: Intravenous acetaminophen with or without ketorolac reduced opioid consumption, opioid-related adverse effects, length of stay, and thereby cost of care following idiopathic scoliosis in adolescents compared with opioids-alone postoperative analgesia strategy.

The Evolving Treatment Patterns of NCAA Division I Football Players by Orthopaedic Team Physicians Over the Past Decade, 2008-2016.

BACKGROUND: Previous studies have analyzed the treatment patterns used to manage injuries in National Collegiate Athletic Association (NCAA) Division I football players. HYPOTHESIS: Treatment patterns used to manage injuries in NCAA Division I football players will have changed over the study period. STUDY DESIGN: Descriptive epidemiology study. LEVEL OF EVIDENCE: Level 5. METHODS: The head orthopaedic team physicians for all 128 NCAA Division I football teams were asked to complete a survey containing questions regarding experience as team physician, medical coverage of the team, reimbursement issues, and treatment preferences for some of the most common injuries occurring in football players. Responses from the current survey were compared with responses from the same survey sent to NCAA Division I team physicians in 2008. RESULTS: Responses were received from 111 (111/119, 93%) NCAA Division I orthopaedic team physicians in 2008 and 115 (115/128, 90%) orthopaedic team physicians between April 2016 and April 2017. The proportion of team physicians who prefer a patellar tendon autograft for primary anterior cruciate ligament reconstruction (ACLR) increased from 67% in 2008 to 83% in 2016 ( P < 0.001). The proportion of team physicians who perform anterior shoulder stabilization arthroscopically increased from 69% in 2008 to 93% in 2016 ( P < 0.0001). Of team physicians who perform surgery for grade III posterior cruciate ligament (PCL) injuries, the proportion who use the arthroscopic single-bundle technique increased from 49% in 2008 to 83% in 2016 ( P < 0.0001). The proportion of team physicians who use Toradol injections prior to a game to help with nagging injuries decreased from 62% in 2008 to 26% in 2016 ( P < 0.0001). CONCLUSION: Orthopaedic physicians changed their injury treatment preferences for NCAA Division I football players over the study period. In particular, physicians have changed their preferred techniques for ACLR, anterior shoulder stabilization, and PCL reconstruction. Physicians have also become more conservative with pregame Toradol injections. CLINICAL RELEVANCE: These opinions may help guide treatment decisions and lead to better care of all athletes.

The R-Enantiomer of Ketorolac Delays Mammary Tumor Development in Mouse Mammary Tumor Virus-Polyoma Middle T Antigen (MMTV-PyMT) Mice.

Epidemiologic studies report improved breast cancer survival in women who receive ketorolac (Toradol) for postoperative pain relief compared with other analgesic agents. Ketorolac is a racemic drug. The S-enantiomer inhibits cyclooxygenases; R-ketorolac is a selective inhibitor of the small GTPases Ras-related C3 botulinum toxin substrate 1 (Rac1) and cell division control protein 42 (Cdc42), which are signaling molecules up-regulated during breast cancer progression and metastasis. The goal of this study was to determine whether R-ketorolac altered breast cancer development in the mouse mammary tumor virus-polyoma middle T-antigen model. Mice were administered ketorolac orally at 1 mg/kg twice daily to approximate the typical human dose. Mammary glands were analyzed for tumor number and immunohistochemical markers of proliferation and differentiation. R-ketorolac treatment significantly reduced mammary epithelial proliferation, based on Ki67 staining, and suppressed tumor development. Proliferative mammary epithelium from R-ketorolac-treated mice displayed greater differentiation, based on significantly higher total E-cadherin and decreased keratin 5 staining than epithelium of placebo-treated mice. No differences were detected in estrogen receptor, progesterone receptor, ß-catenin, or vimentin expression between placebo and R-ketorolac treatment groups. These findings indicate that R-ketorolac treatment slows tumor progression in an aggressive model of breast cancer. R-ketorolac may thus represent a novel therapeutic approach for breast cancer prevention or treatment based on its pharmacologic activity as a Rac1 and Cdc42 inhibitor.

Randomized Controlled Trial Comparing the Effects of 2 Analgesic Drug Protocols in Patients who Received 5 Dental Implants.

PURPOSE: This randomized controlled trial compares postoperative pain and swelling after placing dental implants in patients treated with nonsteroidal anti-inflammatory drugs (NSAIDs) versus NSAIDs and corticosteroids. MATERIALS AND METHODS: Thirty patients received 5 dental implants each in the interforaminal region of the mandible. All patients were treated with ketorolac tromethamine 10 mg, 2 tablets daily for 2 days and amoxicillin 500 mg, 3 tablets daily for 7 days starting 24 hours before surgery. Experimental patients received an im injection of betamethasone 2 mL within 10 hours after surgery. Pain perception, intraoral inflammation (InIn), and extraoral inflammation (ExIn) data were collected 3, 7, and 14 days after surgery. Patients filled out a pain visual analog scale. InIn and ExIn were recorded by observing the existence of 7 signs. RESULTS: One patient was excluded from control group. Pain perception, InIn, and ExIn were not different between groups at each time point. However, these variables were different from the previous time point within each group. CONCLUSION: This study suggests that there is no difference in managing postoperative pain and swelling with betamethasone versus betamethasone and ketorolac.

Comparison of the anti-inflammatory effect of dexamethasone and ketorolac in the extractions of third molars.

This double-blind, split-mouth, and randomized study was aimed to compare the efficacy of dexamethasone and ketorolac tromethamine, through the evaluation of pain, edema, and limitation of mouth opening. Thirty-four individuals aged 18-26 years, having bilateral mandibular third molars, in a similar position, were selected. Two different surgical procedures were performed on the same individual by the single surgeon. For an extraction, the individual received 1 capsule of 10 mg ketorolac tromethamine 1 h before surgery and every 8 h for 2 days. For the extraction of the contralateral side, the individual received 1 capsule of 8 mg dexamethasone 1 h before surgery and 1 placebo capsule every 8 h for 2 days. Sodium metamizol, 500 mg, was given as rescue medication in postoperative. Pain was assessed by the Visual Box Scale-11 points (BS-11) at 24 h postoperative. Edema (metric measurement) and the maximum mouth opening (interincisal) were recorded in the pre-operative, 24 h, 48 h, 72 h and 7 days postoperatively. The results showed that both therapeutic treatments used were effective in the postoperative, and there were no statistically significant differences between the groups for the pain and edema variables. However, for the limitation of mouth opening, 24 h and 7 days postoperatively, the dexamethasone group had a lower limitation of mouth opening, behaving better than the ketorolac for this variable in these periods. Due also to the higher margin of safety, the use of dexamethasone as a single dose becomes a more suitable alternative for use in routine surgical extractions of third molars.

Dor em urgência odontológica: uso de anti-inflamatórios, corticoides e analgésicos em casos de pulpite aguda irreversível / Pain in dental emergency: anti inflammatory use, steroids and painkillers in cases of irreversible acute pulpitis

O objetivo deste estudo foi avaliar o uso do cetorolaco de trometamina 10mg sublingual 30 minutos antes do procedimento de biopulpectomia em pacientes com pulpite irreversível com relação à dor antes do procedimento e nas 48 horas subsequentes, a quantidade de medicação consumida no pós-operatório e tempo esperado para sua utilização. Também foi avaliada a influência da anestesia intrapulpar, o uso da automedicação analgésica antes da procura pelo atendimento e diferença entre gêneros sobre os níveis de dor pré e pós-operatória. Propôs-se avaliar também a necessidade da presença do antibiótico na medicação intracanal, comparando o Otosporin® com hidrocortisona. Participaram da pesquisa 608 pacientes que procuraram o Setor de Urgência Odontológica da Faculdade de Odontologia de Bauru ou o Setor Odontológico do Pronto Socorro Central da Prefeitura Municipal de Bauru, sendo que 34 completaram de forma adequada o protocolo previsto. Foram divididos em 4 grupos que receberam cetorolaco ou placebo como medicação pré-operatória e Otosporin® ou hidrocortisona como medicação intracanal. Foram anotados os valores de intensidade de dor, em uma escala visual analógica, antes da medicação pré-operatória, antes do atendimento, após o atendimento, 1, 2, 4, 12, 24, 48 horas após e quando houve necessidade de medicação pós-operatória para alívio da dor. Também foi anotado se o paciente havia se automedicado e qual a droga utilizada, se houve necessidade de anestesia intrapulpar, a quantidade de medicação consumida pelo paciente no pós-operatório e o tempo esperado para seu consumo. Dos resultados observou-se que os pacientes que receberam cetorolaco como medicação pré-operatória tiveram uma redução significativa da dor em 30 minutos, quando comparado ao placebo. Foi observado que o tempo necessário para a ingestão de medicamentos pós-operatórios não demonstrou diferença significativa entre os grupos, assim como na quantidade de medicação ingerida. O tempo decorrido entre a primeira e a última dose de medicação pós-operatória também não demonstrou diferença estatística. Com relação a anestesia intrapulpar, 78% dos pacientes necessitaram desta técnica, mas devido ao pequeno tamanho da amostra obtida, não foi possível correlacionar o seu uso com a utilização da medicação pós-operatória. Para os pacientes que se automedicaram previamente, não houve diferença significativa em relação à dor inicial. Quando os gêneros foram comparados, não foi possível observar uma diferença estatística significante entre eles com relação aos parâmetros estudados. Também foram descritos no trabalho os motivos de não inclusão dos 574 pacientes que foram abordados durante a realização deste estudo. Com base nos resultados, conclui-se que o cetorolaco diminuiu expressivamente o nível de dor durante a espera pelo atendimento, porém com relação ao tempo esperado pelo paciente para tomar a primeira dose de medicação pós-operatória, a última dose, a quantidade de comprimidos e a frequência de ingestão não demonstrou a mesma diferença. Também não houve diferença no nível de dor inicial entre os pacientes que se automedicaram e os que não fizeram uso dessa prática. Devido ao pequeno número da amostra, não foi possível encontrar uma correlação entre o uso da técnica anestésica intrapulpar e medicação pós-operatória, sugerindo mais estudos futuros.(AU)

The aim of this study was to evaluate the use of ketorolac tromethamine (10mg sublingual taken 30 minutes before pulpectomy in patients with irreversible pulpitis) in pain reduction immediately before the procedure and the 48 subsequent hours, postoperative consumption of analgesic drugs and time for its use. The influence of intrapulpal anesthesia, the use of analgesic self-medication prior to the demand for care and gender difference on the levels of pre- and postoperative pain was also evaluated. It was also proposed assess the need for antibiotic presence in the intracanal medicament, comparing Otosporin® with hydrocortisone. A total of 608 patients who presented to Dental Urgency Sector from Dental School of Bauru (USP) or Emergency Dental Sector from Bauru City Hall were invited to participate, and 34 completed properly planned protocol. They were distributed in 4 groups that received either ketorolac or placebo as preoperative medication and Otosporin® or hydrocortisone as intracanal medication. The rates of pain intensity were recorded by means of a visual analogue scale before pretreatment medication, immediately before the appointment, 1, 2, 4, 12, 24, 48 hours after the appointment, and when there was taken post medication for postoperative pain relief. It was also recorded if the patient had self medicated and which the drug used and, if there was need intrapulpal anesthesia, amount of ketorolac and rescue medication (paracetamol 750mg) consumed by the patient postoperative time and the waitng time for consumption. The results showed that patients receiving Ketorolac as preoperative medication had a significant reduction of pain in 30 minutes compared to placebo. It was observed that the time required for the intake of postoperative drug showed no significant difference between groups, as well as the amount of medication intake. The time elapsed between the first and last dose of postoperative medication also showed no statistical difference. Concerning intrapulpal anesthesia, 78% of patients required for this technique, but because of the small sample size obtained it was impossible to correlate their use with the use of postoperative medication. For patients who practiced self medication previously, there was no significant difference with respect to initial pain. When genders were compared, it was not possible to observe a statistically significant difference between them regarding the parameters studied. Were also described in the study the reasons of non-inclusion of 574 patients that were addressed during this study. Based on the results, it is concluded that ketorolac significantly decreased the level of pain during the waiting time, but with respect to the time length for the patient to take the first dose of postoperative medication, the last dose, the number of tablets and taken frequency did not show the same difference. There was no difference in the initial level of pain among patients who practiced self medication and those who did not use this practice. Due to the small sample size, it was not possible to find a correlation between the use of the anesthetic technique intrapulpal and postoperative medication, suggesting more future studies.(AU)

Prospective, Randomized Study Comparing the Effect of 0.1% Nepafenac and 0.4% Ketorolac Tromethamine on Macular Thickness in Cataract Surgery Patients With Low Risk for Cystoid Macular Edema.

PURPOSE: This study aimed to compare the short-term efficacy of 0.1% nepafenac with that of 0.4% ketorolac tromethamine in patients with low risk factors for cystoid macular edema (CME) undergoing phacoemulsification. DESIGN: A prospective, randomized, parallel-assignment efficacy trial. METHODS: Two hundred eyes of 200 patients were randomized into 2 groups, one receiving nepafenac and the other receiving ketorolac perioperatively. Primary outcome measures were change in central macular thickness (CMT) at the 30th postoperative day and the incidence of possible subclinical CME (increase in CMT of >10 and >40 µm from baseline) on ocular coherence tomography (OCT). Secondary outcomes measured were the incidence of definite subclinical CME on OCT (>40 µm increase in CMT from baseline) and clinically significant CME at 1-month follow-up. A subgroup analysis of diabetic and hypertensive patients included in the study was made postoperatively. RESULTS: Difference in CMT at 1 month (P = 0.43) and presence of possible subclinical CME (P = 0.18) were comparable in both groups. The incidence of possible subclinical CME was 22.7%. None of the patients developed clinical CME or definite subclinical CME. In the diabetic subgroup, nepafenac showed significantly less CMT difference than ketorolac did at 1 week after the operation (P = 0.04) but not at 1 month (P = 0.09). CONCLUSIONS: Postoperative macular thickening after cataract surgery in eyes with low CME risk is similar with nepafenac and ketorolac. A larger population of diabetic patients should be studied to verify any beneficial effect of nepafenac on this subgroup.

Is ketorolac safe to use in plastic surgery? A critical review.

BACKGROUND: Ketorolac tromethamine is a nonsteroidal anti-inflammatory drug (NSAID) that provides postoperative pain control and reduces narcotic requirements. However, concerns regarding postoperative hematoma have limited its use in plastic surgery. OBJECTIVES: Our goal is to critically review the risk of bleeding with ketorolac in plastic surgery patients, with a focus on aesthetic surgery. METHODS: A PubMed/Medline literature search of clinical trials using the keywords "surgery" and "NSAID" yielded 2574 results. Of these results, 1036 included ketorolac and twelve involved plastic surgery patients. Six studies reported postoperative hematoma rates: three prospective randomized trials, two retrospective reviews, and one case series. These were subjected to statistical analysis to determine if an association existed between ketorolac and postoperative hematomas. RESULTS: Six papers reported 981 cases. Ketorolac use resulted in similar hematoma rates when compared to control groups, 2.5% (12 of 483) versus 2.4% (12 of 498), respectively (P = .79). There were no reported hematomas associated with ketorolac in over 115 patients undergoing aesthetic facial procedures. Hematoma rates of those undergoing aesthetic breast surgery, including reduction and augmentation mammoplasties, were 4.3% (11 of 257) in the ketorolac group versus 2.2% (6 of 277) in controls (P = .59). Reduction in postoperative narcotic use and improved pain scores was also reported. CONCLUSIONS: Our literature review did not find a significant association between hematoma formation and ketorolac use in a variety of plastic surgery procedures. These findings are similar to those in other surgical subspecialties.

[Efficacy observation of 0.1% bromfenac sodium eye drops on relieving the post-LASEK irritative symptoms].

OBJECTIVE: To observe the efficacy of bromfenac sodium eye drops on relieving the irritative symptoms after LASEK surgery. METHODS: Sixty-four people who had received LASEK surgery were randomly divided into two groups, observing the right eye for each group. group A was given 0.1% bromfenac sodium eye drops twice a day in three days before surgery and one day after surgery; group B was given 0.5% ketorolac tromethamine (acular) eye drops four times a day in three days before surgery and on day after surgery. In the 1(st), 3(rd), 5(th) and 7(th) day after surgery, irritative symptoms grade, duration of irritation, time for corneal epithelial healing, and uncorrected visual acuity were observed and compared between the two groups. RESULTS: 0.1% no discomfort in group A with bromfenac sodium eye drops was observed while 0.5% ketorolac tromethamine eye drops caused tingling, burning discomfort that lasted for 2-3 seconds in 16 of the 28 subjects (87.5%). No significant difference was observed between the irritation grades of group A and B (Z = -1.625, P = 0.104); the duration of irritative symptom was significantly shorter in group A than that in group B (Z = -2.895, P = 0.004) . No significant difference was observed between the time of healing and visual acuity recovery of the two groups. CONCLUSION: 0.1% bromfenac sodium eye drops can effectively relieve the post-LASEK irritative symptoms, and it is better tolerated than 0.5% ketorolac tromethamine eye drops.

Comparison of topical dorzolamide and ketorolac treatment for cystoid macular edema in retinitis pigmentosa and Usher's syndrome.

PURPOSE: To investigate the topical effect of dorzolamide versus ketorolac on retinitis pigmentosa (RP) and Usher's syndrome (US) macular edema. METHODS: Prospective, randomized and interventional study. A total of 28 eyes of 18 patients were included. Five eyes had US, 23 had RP. Fifteen eyes were allocated to ketorolac tromethamine 0.5% (4 drops daily regimen) and 13 eyes to dorzolamide hydrochloride 2% (3 drops daily regimen) treatment groups. Snellen's best-corrected visual acuity (BCVA), foveal thickness (FT) and foveal zone thickness (FZT) measured by Stratus® optical coherence tomography (OCT) were evaluated at baseline, 1, 3, 6 and 12 months after treatment. RESULTS: Patients assigned to ketorolac had a baseline BCVA of 0.37 ± 0.17 logMAR which improved at the end of 1 year to 0.28 ± 0.16 (p = 0.02). Three eyes (20%) of 2 patients improved by 7 letters or more. Mean FT and FZT did not change significantly during the study follow-up. After 1 year of treatment, 4 eyes (27%) of 3 patients showed an improvement of at least 16% of FT and 11% of FZT. Patients assigned to dorzolamide had a baseline BCVA of 0.48 ± 0.34 logMAR which improved in the first 6 months (0.40 ± 0.30; p = 0.01), with a decrease at 1 year (0.42 ± 0.27; p = 0.20). Seven eyes (54%) of 5 patients had an improvement of 7 letters or more. Mean FT and FZT did not change significantly either. After 1 year of treatment, 3 eyes (23%) of 2 patients showed an improvement of at least 16% on FT and 11% on FZT. CONCLUSIONS: RESULTS suggest that dorzolamide and ketorolac might improve visual acuity and therefore be of interest in selected cases. No relationship between retinal thickness fluctuation and visual acuity was found. Sample size was a limitation to the study.

Serous retinal detachment and cystoid macular edema in a patient with Wyburn-Mason syndrome.

Wyburn-Mason syndrome is a rare phacomatosis characterized by unilateral arteriovenous malformations (AVMs) involving the brain, retina, and (rarely) the skin. The diagnosis is concluded with dilated fundus examination and markedly dilated tortuous vascular loops with arteriovenous communications on fluorescent angiography. We present a 14-year-old male patient with Wyburn-Mason syndrome who developed serous macular neuroretinal detachment, cystoid macular edema (CME), and consequent visual deterioration in the left eye. To the best of our knowledge, this is the first report of a patient with Wyburn-Mason syndrome who developed serous retinal detachment and CME.
