ABSTRACT
El dolor neuropático es común en la práctica clínica. Se estima que afecta entre el 2 y 3 % de la población a nivel global. Una cantidad considerable de pacientes presentan dolor refractario a tratamientos existentes, volviéndolo un reto diagnóstico y terapéutico. El objetivo de este estudio es describir el uso clínico de lidocaína intravenosa para manejo de dolor neuropático no oncológico en adultos. La búsqueda de información se realizó consultando las bases de datos HINARI, SciELO y PubMed. Se seleccionaron artículos en inglés y español de 2017 a 2021. Se utilizaron artículos originales, ensayos clínicos, revisiones bibliográficas y metaanálisis. Las causas de dolor neuropático en las que ha sido utilizada la lidocaína son la neuralgia posherpética, neuropatía diabética y neuralgia del trigémino. El uso de lidocaína intravenosa demostró que disminuye la intensidad del dolor; sin embargo, al compararlo con otros fármacos de primera línea no hay diferencias a largo plazo. La mayoría de efectos secundarios se presentan en el sistema nervioso, gastrointestinal y cardiovascular. La lidocaína intravenosa como monoterapia para manejo de dolor neuropático no oncológico, si bien fue eficaz a corto plazo con dosis de 3-5 mg/Kg, no tuvo un efecto persistente y duradero
Neuropathic pain is common in clinical practice; it is estimated that 2 to 3 % of the global population is affected; a considerable number of patients present pain refractory to existing treatments, making it a diagnostic and therapeutic challenge. The objective of this study is to describe the clinical use of intravenous lidocaine for the management of non-cancer neuropathic pain in adults. The information search was performed by consulting the HINARI, SciELO and PubMed databases. Articles with an obsolescence of no more than five years, both in English and Spanish, were selected. Original articles, clinical trials, bibliographic reviews and meta-analyses were used. The causes of neuropathic pain in which lidocaine has been used were postherpetic neuralgia, diabetic neuropathy, and trigeminal neuralgia. The use of intravenous lidocaine has been shown to decrease pain intensity; however, when compared with other first line drugs, there are no long-term differences. Most side effects occur in the nervous, gastrointestinal, and cardiovascular systems. Intravenous lidocaine as monotherapy for the management of non-cancer neuropathic pain, although effective in the short term with doses of 3-5 mg/Kg, does not have a persistent and long-lasting effect

La lidocaína es el anestésico local más utilizado a nivel mundial para la cirugía de catarata. También se usa de manera común en otras intervenciones quirúrgicas oftalmológicas del segmento anterior, la superficie del globo ocular, los párpados y vías lagrimales, así como en el segmento posterior del ojo. Esta revisión pretende brindar una actualización sobre las principales características, los efectos y vías de administración de la lidocaína usada en la oftalmología. Se realizó una búsqueda sistemática sobre el tema en publicaciones científicas indexadas en bases de datos, cuya información recopilada se resumió en este trabajo. La lidocaína se presenta en múltiples formas farmacéuticas, con variedad en concentración y formulación. Por lo general, para inyección se usan las concentraciones al 0,5 por ciento, 1 por ciento y 2 por ciento, para anestesia tópica en gel al 2 por ciento y en solución oftálmica al 4 por ciento. Su efecto como anestésico local es bien conocido, a nivel ocular se puede conseguir a través de inyecciones perioculares e intraoculares o mediante su aplicación tópica. Este efecto anestésico de la lidocaína ofrece cierta capacidad de dilatación pupilar, el cual se ha estudiado y aprovechado con frecuencia en los últimos años. Hoy día se encuentran en estudio otros efectos de la lidocaína a nivel local y sistémico. Los usos de la lidocaína en la oftalmología actual, están respaldados fundamentalmente por su eficacia y seguridad comprobadas en el tiempo(AU)
Lidocaine is the most widely used local anesthetic worldwide for cataract surgery. It is also commonly used in other ophthalmic surgical procedures of the anterior segment, surface of the eyeball, eyelids and lacrimal ducts, as well as in the posterior segment of the eye. This review aims to provide an update on the main characteristics, effects and ways of administering lidocaine used in ophthalmology. A systematic search on the subject was carried out in scientific publications indexed in databases, the information collected was summarized in this work. Lidocaine comes in multiple pharmaceutical forms, with a variety of concentrations and formulations. Generally, 0.5 percent, 1 percent and 2 percent concentrations are used for injection, 2 percent for topical anesthesia in gel and 4% in ophthalmic solution. Its effect as a local anesthetic is well known, at ocular level it can be achieved through periocular and intraocular injections or by topical application. This anesthetic effect of lidocaine offers some pupillary dilation capacity, which has been frequently studied and exploited in recent years. Other local and systemic effects of lidocaine are currently under study. The uses of lidocaine in ophthalmology today are supported primarily by its time-tested efficacy and safety(AU)

Resumen: Introducción: contar con una analgesia efectiva en el postoperatorio es fundamental para evitar complicaciones asociadas a dolor, en pacientes sometidos a colecistectomía laparoscópica. Objetivos: evaluar la efectividad de la lidocaína en infusión transoperatoria para el control de dolor postoperatorio en pacientes sometidos a colecistectomía laparoscópica. Material y métodos: se realizó un estudio experimental, aleatorizado, ciego simple, en pacientes sometidos a colecistectomía laparoscópica en el Hospital General Regional No. 1 en Obregón. Se dividieron en dos grupos de forma aleatoria, al grupo L se le aplicó lidocaína 1.5 mg/k en infusión, al grupo P se le aplicó placebo. Se realizó un análisis estadístico en SPSS v. 22 y se consideró significativa una p < 0.05. Resultados: se observó un adecuado manejo del dolor en los pacientes del grupo L a su ingreso a la Unidad de Recuperación Postanestésica (URPA) (p = 0.002), menor consumo de fentanyl transoperatorio sin diferencia estadística contra placebo (p = 0.086), menor uso de analgesia de rescate postquirúrgica (p = 0.045). Conclusiones: la infusión de lidocaína es efectiva para el manejo del dolor postquirúrgico inmediato, así como disminución de consumo de opioides y dosis de rescate analgésico, con una baja incidencia de náuseas y vómito, pero se asoció a hipotensión transoperatoria.
Abstract: Introduction: having an effective analgesia in the postoperative period is essential to avoid complications associated with pain in patients undergoing laparoscopic cholecystectomy. Objectives: test the effectiveness of intravenous lidocaine for postoperative pain in cholecystectomized patients by laparoscopy. Material and methods: an experimental, randomized, single-blind study was carried out in patients who underwent laparoscopic cholecystectomy at the No. 1 Regional General Hospital in Obregon, Sonora. They were divided into two groups randomly: group L to whom we applied lidocaine 1.5 mg/k in infusion and group P to whom placebo was applied. A statistical analysis was performed in SPSS v. 22 and a p < 0.05 was considered significant. Results: adequate pain management was observed in patients of group L upon admission to PACU (p = 0.002), lower consumption of transoperative fentanyl without statistical difference against placebo (p = 0.086), lower use of post-surgical rescue analgesia (p = 0.045), but higher incidence of adverse effects such as hypotension and bradycardia (p = 0.024). Conclusions: the infusion of lidocaine is effective for the management of immediate postsurgical pain; as well it decreases opioid consumption and analgesic rescue dose, with a low incidence of nausea and vomiting, but associated with hypotension after surgery.

Resumen: Introducción: La tos es una respuesta fisiológica de protección de la vía aérea, produce aerosoles que se identifican por imagen y alcanza una velocidad de hasta ocho metros por segundo. La extubación produce tos, hipertensión, taquicardia, apnea y laringoespasmo, existen métodos para minimizar su aparición. Debido a la pandemia de COVID-19 se han utilizado como profilaxis del reflejo tusígeno, la lidocaína intravenosa y el bloqueo del nervio laríngeo superior. El objetivo fue compararlos en la inhibición de la tos. Material y métodos: Se seleccionaron pacientes entre 18-60 años, cirugía electiva con anestesia general balanceada, ASA 1-3, con intubación menor a tres horas. Se aleatorizó un total de 90 pacientes, 45 en cada grupo, se eliminó un total de 10 pacientes por presentar inestabilidad hemodinámica al final de la cirugía o por no administrar dosis intravenosa de lidocaína en el tiempo establecido. Resultados: No hubo diferencia estadísticamente significativa en el número de pacientes que presentaron tos en ambos grupos (13 vs 10, p = 0.4684), de éstos se obtuvo una diferencia estadísticamente significativa en el número de decibeles a favor del grupo de bloqueo (75.6 vs 67, p < 0.001). Conclusiones: El bloqueo (selectivo) presenta menos aerolización que la lidocaína intravenosa en la extubación.
Abstract: Introduction: Coughing is a physiological response to protect the airway, it produces aerosols that are identified by imaging reaching a speed of up to 8 meters per second. Extubation produces cough, hypertension, tachycardia, apnea and laryngospasm, there are methods to minimize its occurrence. Due to the COVID-19 pandemic, intravenous lidocaine and superior laryngeal nerve block have been used as cough reflex prophylaxis. The aim was to compare them in cough inhibition. Material and methods: Patients aged 18-60 years, elective surgery with balanced general anesthesia, ASA 1-3, with intubation less than 3 hours, were selected. A total of 90 patients were randomized, 45 in each group. A total of 10 patients were eliminated because they presented hemodynamic instability at the end of surgery, and because the intravenous dose of lidocaine was not administered within the established time. Results: There was no statistically significant difference in the number of patients who presented cough in both groups (13 vs 10, p = 0.4684), of these there was a statistically significant difference in the number of decibels in favor of the block group (75.6 vs 67, p < 0.001). Conclusions: Block presents less aerolization than intravenous lidocaine in extubation.
ABSTRACT
ABSTRACT BACKGROUND AND OBJECTIVES: Neuropathic pain is a chronic condition with a significant burden for patients, society, and healthcare systems. Due to neuropathic complexity, its management must be different than the one for nociceptive pain. First-line systemic treatments may be associated with dose-dependent adverse events and drug-drug interactions. On the other hand, topical treatments have less systemic adverse events, with the 5% lidocaine transdermal patch being recommended for firstor second line of treatment for neuropathic pain according to various international guidelines. The aim of this study is to present three cases of localized neuropathic pain due to nerve compression managed with 5% lidocaine transdermal patch. CASE REPORTS: The cases of three adult patients (>40 years old) with pain or tingling for a long period of time and their outcomes with treatment with 5% lidocaine transdermal patch for a prolonged duration were investigated. All three cases report a significant improvement in pain. CONCLUSION: The results of the reported cases revealed that a 5% lidocaine transdermal patch represents an effective, safe and tolerable and noninvasive option for the management of localized neuropathic pain due to peripheric nerve compression.
RESUMO JUSTIFICATIVA E OBJETIVOS: A dor neuropática é uma condição crônica com impactos significativos para o paciente, a sociedade e o sistema de saúde. Pela sua complexidade neuropática, a sua abordagem deve ser diferente da dor nociceptiva. Os tratamentos sistêmicos de primeira linha para a dor neuropática podem estar associados à incidência de eventos adversos dose-dependentes e interações farmacológicas. Por outro lado, os fármacos tópicos apresentam menor incidência de eventos adversos sistêmicos, sendo o emplastro de lidocaína a 5% recomendado como primeira ou segunda linha de tratamento para essa condição em diversos guidelines internacionais. O objetivo deste estudo foi apresentar três casos clínicos de dor neuropática localizada por compressão nervosa manejados com o emplastro de lidocaína a 5%. RELATO DOS CASOS: Três pacientes com idade superior a 40 anos e queixas de dor ou parestesia de longa duração foram manejados com emplastro de lidocaína a 5% em tratamento prolongado, com melhora da intensidade de dor expressiva. CONCLUSÃO: Os resultados dos casos reportados revelaram que o emplastro de lidocaína a 5% se apresentou como uma opção terapêutica eficaz, segura, bem tolerada e não invasiva no manejo da dor neuropática localizada por compressão nervosa periférica.

ABSTRACT
La exodoncia de los terceros molares inferiores es uno de los procedimientos clínicos más comunes en el cual el control del dolor mediante el bloqueo anestésico del nervio alveolar inferior, bucal y lingual resulta ser fundament al y la manera más común de hacerlo es mediante la infiltración de soluciones de anestesia local. Entre ellos la lidocaína y articaína son algunos de los más comunes y pueden estar asociado a vasoconstrictores como la epinefrina que puede provocar aumento de la presión arterial y frecuencia cardíaca razón por la cual se hace necesario la monitorización de cambios hemodinámicos durante la cirugía. Describir los cambios hemodinámicos asociados al uso de lidocaína al 2 % y/ o articaína al 4 % en la presión sistólica y diastólica, frecuencia cardiaca y saturación parcial de oxígeno en relación a distintos tiempos operatorios. Se realizó una revisión sistemática en las bases de datos de PubMed, SCOPUS, Web of Science y Sciencedirect. Se analizaron 7 ensayos clínicos controlados en los que utilizaron articaína al 4 % y/o lidocaína al 2 % con epinefrina al 1:100,000 y/o 1:200,000 en volúmenes de 1,8 a 5,4 mL, en los cuales evaluaron la presión sistólica y diastólica, frecuencia cardiaca y saturación parcial de oxígeno en distintos tiempos de la cirugía. Si bien hubo cambios en PAS, PAD, FC y SPO2, todas se mantuvieron dentro de rangos normales bajo el uso de articaína al 4 % y lidocaína al 2 % con epinefrina 1:100,000 y/o 1:200,000 a volúmenes de 1,8 a 5,4mL medidas a distintos tiempos operatorios.
The extraction of lower third molars is one of the most common clinical procedures in which pain control through anesthetic blockade of the lower alveolar, buccal and lingual nerves turns out to be essential and the most common way to do it is through the infiltration of solutions of local anesthesia. Among them, lidocaine and articaine are some of the most common and may be associated with vasoconstrictors such as epinephrine, which can cause an increase in blood pressure and heart rate, which is why it is necessary to monitor hemodynamic changes during surgery. To describe the hemodynamic changes associated with the use of 2 % lidocaine and/or 4 % articaine in systolic and diastolic pressure, heart rate and partial oxygen saturation in relation to different operative times. A systematic review was carried out in the PubMed, SCOPUS, Web of Science and Sciencedirect databases. Seven controlled clinical trials were analyzed in which 4 % articaine and/or 2 % lidocaine were used with epinephrine at 1:100,000 and/or 1:200,000 in volumes of 1,8 to 5,4 mL, in which systolic pressure was evaluated. and diastolic, heart rate and partial oxygen saturation at different times of surgery. Although there were changes in SBP, DBP, HR and SPO2, all remained within normal ranges under the use of 4 % articaine and 2 % lidocaine with epinephrine 1:100,000 and/or 1:200,000 at volumes of 1,8 to 5 .4mL measured at different operative times.

ABSTRACT Introduction: For patients with severe hip osteoarthritis without clinical or socioeconomic conditions for total hip replacement, the obturator nerve block may serve for pain control and functional improvement. Either lidocaine or phenol are used, although the latter is expected to last longer. Objectives: Compare hip pain and functional performance after obturator nerve block with phenol versus lidocaine in patients with severe hip osteoarthritis who failed conservative treatment. Methodology: Forty-four patients scheduled for total arthroplasty due to severe osteoarthritis were randomized to the anterior branch of the obturator nerve with phenol (PG) or 1% lidocaine (LG), guided by electrical stimulation. Patients were evaluated with VAS, WOMAC, and pressure pain dolorimetry before the procedure and in the first and fourth months afterward. Results: Both groups improved significantly in pain control, pressure dolorimetry and functioning in the first month with reduced effect after 4 months, although the scores were still better than baseline. No statistical difference could be noticed between the groups. Severe adverse effects were not reported. Conclusion: Both lidocaine and phenol are equally effective and safe in the obturator nerve block for the control of pain and improvement in functioning in patients with severe hip OA. Evidence Level I; Randomized control trial, double-blind .
RESUMO Introdução: Em pacientes com osteoartrite grave do quadril, sem condições clínicas ou socioeconômicas para a substituição total do quadril, o bloqueio do nervo obturador pode servir para o controle da dor e ganho funcional. Pode-se usar lidocaína ou fenol, embora seja esperado que o último apresente maior duração. Objetivo: Comparar a dor no quadril e o desempenho funcional após o bloqueio do nervo obturador com fenol versus lidocaína em pacientes com osteoartrite grave do quadril que não obtiveram sucesso no tratamento conservador. Metodologia: Quarenta e quatro pacientes programados para artroplastia total devido à osteoartrite grave foram randomizados para o ramo anterior do nervo obturador com fenol (PG) ou lidocaína a 1% (LG), guiados por estimulação elétrica. Os pacientes foram avaliados com EVA, WOMAC e dolorimetria de dor por pressão antes do procedimento e no primeiro e quarto meses seguintes. Resultados: Ambos os grupos apresentaram melhora significativa no controle da dor, na dolorimetria por pressão e na funcionalidade no primeiro mês, com efeito reduzido após quatro meses, embora as pontuações ainda fossem melhores do que a linha de base. Não foi possível observar nenhuma diferença estatística entre os grupos. Não foram relatados efeitos adversos graves. Conclusão: Tanto a lidocaína quanto o fenol são igualmente eficazes e seguros no bloqueio do nervo obturador para o controle da dor e melhora da funcionalidade em pacientes com OA grave de quadril. Nível de evidência I; Estudo clínico randomizado,duplo cego .
ABSTRACT
Aim: To investigate the precipitate formed from the interaction between 2% lidocaine hydrochloride with adrenaline (LA) with 2.5% sodium hypochlorite (NaOCl) and 0.2% chitosan nanoparticles on root canal dentin, using scanning electron microscopy (SEM). Material and Methods: Sixty mandibular premolars were decoronated, and the root length standardised. The specimens were randomly distributed into the following groups: Group 1 (control): 2% LA mixed with sterile water without root canal instrumentation, Group 2: 2% LA with 2.5% NaOCl in water without root canal instrumentation, and Group 3: 2% LA with 0.2% chitosan nanoparticles in water without root canal instrumentation. Teeth specimens were split and subjected to SEM analysis at cervical, middle, and apical root thirds. On observing precipitate formation in Group 2, 10 premolars were decoronated and treated with 2% LA and 2.5% NaOCl and subjected to root canal instrumentation. Results: Group 1 and Group 3 showed patent dentinal tubules and no precipitate formation. Group 2 showed precipitate blocking dentinal tubules in all the three sections, and the precipitate could not be removed completely after cleaning and shaping. Conclusion: NaOCl forms an insoluble precipitate on interaction with local anaesthetic solution that cannot be removed after chemo-mechanical preparation. Chitosan nanoparticles do not form any such precipitate and show patent dentinal tubules. Hence, chitosan can be used as a flushing irrigant.
Objetivo: Investigar el precipitado formado a partir de la interacción entre el clorhidrato de lidocaína al 2% con adrenalina (LA), el hipoclorito de sodio al 2,5% (NaOCl) y nanopartículas de quitosano al 0,2% en la dentina del conducto radicular, mediante microscopía electrónica de barrido (SEM). Material y Métodos: Se decoraron 60 premolares mandibulares y se estandarizó la longitud de la raíz. Los especímenes se distribuyeron aleatoriamente en los siguientes grupos: Grupo 1 (control): 2% la que fue mezclado con agua estéril sin instrumentación del conducto radicular, Grupo 2: 2% LA con 2,5% de NaOCl sin instrumentación del conducto radicular y Grupo 3: 2 % LA con 0,2% de nanopartículas de quitosano sin instrumentación del conducto radicular. Las muestras de dientes se dividieron y se sometieron a análisis SEM en los tercios radiculares cervical, medio y apical. Al observar la formación de precipitado en el Grupo 2, 10 premolares fueron decorados y tratados con LA al 2% y NaOCl al 2,5% y sometidos a instrumentación de conductos radiculares. Resultado: El Grupo 1 y el Grupo 3 mostraron túbulos dentinarios permeables y sin formación de precipitados. El grupo 2 mostró precipitado que bloqueaba los túbulos dentinarios en las tres secciones, y el precipitado no se pudo eliminar por completo después de limpieza y conformación. Conclusión: el NaOCl forma un precipitado insoluble al interactuar con la solución anestésica local que no se puede eliminar después de la preparación quimiomecánica. Las nanopartículas de quitosano no forman ningún precipitado de este tipo y muestran túbulos dentinarios permeables. Por lo tanto, el quitosano se puede utilizar como irrigante para el lavado.

Abstract Optimum pain management, minimizing chronic complications and ensuring a good safety profile, is growing in importance day by day. Lidocaine infusion has an adequate safety profile and several desirable characteristics in the clinical setting. This review describes the characteristics of this drug, as well as its potential indications. Moreover, it describes the basic concepts around lidocaine use, mechanisms of action and clinical applications, as well as the use of infusions in acute pain and repercussions in chronic pain. A review of the literature in English and Spanish was conducted in several databases, with no publication date limit. Articles considered relevant, without including the grey literature, were selected independently. Lidocaine infusion is an option for acute postoperative pain control in major surgery and contributes to opioid sparing and reduced length of stay, with ample evidence in abdominal surgery, rendering it an option to recommend in various protocols. It has an acceptable safety profile in special populations and it is considered useful to diminish the incidence of persistent, chronic and neuropathic pain related to the surgical procedure.

Abstract Introduction Administering systemic lidocaine has been shown to deliver effective analgesia for both cancer-related and non-cancer pain. Adverse effects and toxicity are rare with controlled administration. Objective To report the results obtained after the indication to manage with IV lidocaine infusion to control neuropathic pain fiares in 9 cancer patients. Methodology Observational, descriptive, case series-type study. A search was conducted in the files of the Pain and Palliative Care Service of the National Cancer Institute - Instituto Nacional de Cancerología - in Bogotá. Patients over 18 years old diagnosed with cancer, who experienced high intensity neuropathic pain and with the cognitive ability to rate their pain in a numerical analogue scale (NAS), without any absolute contraindications for the use of IV lidocaine were included; patients were assessed between September 27 and November 21, 2019. Results 9 patients experiencing a pain flare-up which was characterized as neuropathic were registered, of which 89 % had some improvement following the administration of an initial lidocaine bolus. After one hour, 60 % reported over 40% improvement in the initial NAS. After 24 hours all patients had experienced some improvement, with a reduction of 46% in the pain scale as compared to the baseline. Conclusions In this series of cases, the intravenous infusion of lidocaine as an option for the management of neuropathic pain flares seems to reduce pain intensity following the initial bolus administration.

ABSTRACT
Os anestésicos locais são essenciais em diversos procedimentos médicos e odontológicos. Funcionam estabilizando as membranas neuronais e inibindo a transmissão de impulsos neurais, o que permite a realização desses procedimentos com mais segurança e sem dor. As reações adversas a drogas são definidas pela Organização Mundial da Saúde como todos os efeitos nocivos, não intencionais e indesejáveis de uma medicação, que ocorrem em doses usadas para prevenção, diagnóstico e tratamento. As reações de hipersensibilidade são reações adversas do tipo B, imprevisíveis, que clinicamente se assemelham a reações alérgicas e podem ou não envolver um mecanismo imune. As reações de hipersensibilidade verdadeiras aos anestésicos locais são raras, apesar de superestimadas. Nesta revisão destacamos a necessidade de uma avaliação completa dos pacientes com suspeita de reação alérgica aos anestésicos locais, incluindo a investigação de outros possíveis alérgenos que tenham sido utilizados no procedimento, como analgésicos, antibióticos e látex. A estratégia de investigação e seleção de pacientes para testes deve se basear na história clínica. Dessa forma, poderemos fornecer orientações mais assertivas e seguras aos pacientes.
Local anesthetics are essential in many medical and dental procedures. They work by stabilizing neuronal membranes and inhibiting the transmission of neural impulses, which allows these procedures to be performed more safely and without pain. Adverse drug reactions are defined by the World Health Organization as all harmful, unintended and undesirable effects of a medication, which occur at doses used for prevention, diagnosis and treatment. Hypersensitivity reactions are unpredictable type B adverse reactions that clinically resemble allergic reactions and may or may not involve an immune mechanism. True hypersensitivity reactions to local anesthetics are rare, although overestimated. In this review, we highlight the need for a thorough evaluation of patients with suspected allergic reaction to local anesthetics, including investigation of other possible allergens that may have been used in the procedure, such as analgesics, antibiotics and latex. The investigation strategy and patient selection for testing should be based on clinical history. In this way, we will be able to provide more assertive and safe guidelines to patients.

Abstract Introduction: The use of intravenous lidocaine infusion has increased over the past decade as part of a multimodal approach to analgesia in adults; however, information about its safety and tolerability in the pediatric population is limited. Methods: Acute pain management using lidocaine infusion in eleven patients treated in the pediatric intensive care unit. Results: Five cases of postoperative abdominal pain and six cases of non-operative abdominal pain. Two cases were cancer patients affected by neutropenic colitis. Analgesic control achieved was good. Conclusion: Lidocaine infusions are apparently a safe option for the management of acute pain, either post-operative or not, in the pediatric population.

ABSTRACT
Resumen El dolor neuropático localizado (DNL) es de origen periférico y se caracteriza por áreas circunscritas de dolor con sensibilidad anormal de la piel o síntomas espontáneos característicos de dolor neuropático, por ejemplo, dolor urente. Se debe resaltar que el DNL está confinado a un área específica no mayor a una hoja de papel tamaño carta. El DNL representa 60 % de las condiciones de dolor neuropático. No existe una única etiología. El abordaje diagnóstico es similar al de otros síndromes dolorosos neuropáticos. Se utilizan herramientas diagnósticas generales para evaluar las características clínicas. En la actualidad no existen guías específicas de manejo del DNL, por lo que se utilizan las guías para dolor neuropático en general. En las guías de la Sociedad Canadiense de Dolor se incluyen los tratamientos tópicos como parte de las estrategias de segunda línea. Pese a la falta de guías, los parches de lidocaína a 5 % y los parches de capsaicina a 8 % han demostrado ser efectivos en modelos de DNL.
Abstract Localized neuropathic pain (LNP) is of peripheral origin and is characterized by circumscribed areas of pain with abnormal skin sensitivity or spontaneous symptoms that are characteristic of neuropathic pain, e.g. burning pain. It should be noted that LNP is confined to a specific area no larger than a letter size sheet of paper. LNP accounts for 60 % of neuropathic pain conditions. There is no single etiology of LNP. The diagnostic approach is similar to that for other neuropathic pain syndromes. General diagnostic tools are used to assess clinical features. So far, there are no specific guidelines for the management of LNP; for this reason, guidelines for general neuropathic pain are used. Topical treatments are included as part of second-line strategies in the Canadian Pain Society guidelines. Despite the lack of guidelines, 5 % lidocaine patches and 8 % capsaicin patches have been proven effective in LNP models.

Introducción: El estudio y tratamiento del dolor ha sido una de las preocupaciones más importantes en los últimos 30 años en el ámbito médico mundial. Desde hace varias décadas a nivel internacional se realizan estudios sobre el efecto del tramadol y la lidocaína como analgésicos intraoperatorio, con el fin de obtener una adecuada analgesia durante el procedimiento quirúrgico y el periodo posoperatorio inmediato. Objetivo: Comparar el efecto analgésico del tramadol y la lidocaína durante el período transoperatorio en caninos programados para intervención quirúrgica. Método: Se realizó un estudio prospectivo, comparativo, con animales programados para tratamiento quirúrgico por presentar tumores periféricos. Se incluyeron 10 animales divididos en 2 grupos. El grupo control (G-C) que recibió lidocaína sin preservo (lidocaína SP) en infusión continua durante el procedimiento quirúrgico y el grupo 1 (G-1) que se le administró tramadol endovenoso previo al acto quirúrgico. Se evaluaron variables hemodinámicas y de oxigenación como indicadores indirectos de dolor transoperatorio. Resultados: La muestra fue homogénea para la edad y el sexo. El comportamiento de las variables hemodinámicas resultó más estable durante la infusión de lidocaína. La saturación periférica de oxígeno fue similar con ambos medicamentos, así como la temperatura. Conclusiones: La infusión intravenosa de lidocaína SP durante el periodo transoperatorio en caninos oncológico demostró una mejor efectividad analgésica en comparación con el tramadol aplicado preoperatoriamente, según los parámetros evaluados(AU)
Introduction: Study and treatment of pain has been one of the most important concerns in the last thirty years in the worldwide medical field. For several decades, international studies have been carried out on the effect of tramadol and lidocaine as intraoperative analgesics, in order to achieve adequate analgesia during surgical procedures and the immediate postoperative period. Objective: To compare the analgesic effect of tramadol and lidocaine during the intraoperative period in canines scheduled for surgical intervention. Method: A prospective, comparative study was carried out with animals scheduled for surgical treatment due to peripheral tumors. Ten animals were included, divided into two groups: the control group, which received lidocaine without preservation in continuous infusion during the surgical procedure, and group 1, which was administered intravenous tramadol prior to the surgical act. Hemodynamic and oxygenation variables were assessed as indirect indicators of intraoperative pain. Results: The sample was homogeneous for age and sex. The behavior of the hemodynamic variables was more stable during the lidocaine infusion. Peripheral oxygen saturation was similar in both drugs, as well as temperature. Conclusions: Intravenous infusion of lidocaine without preservation during the intraoperative period in oncological canines showed better analgesic effectiveness compared to tramadol applied preoperatively, according to the parameters assessed(AU)

Introducción: La alcalinización de la lidocaína ha resultado ser exitosa en el bloqueo del nervio dentario inferior, sin embargo, existen resultados contradictorios respecto a su eficacia clínica. Objetivo: Determinar el efecto de la lidocaína 2 por ciento con adrenalina 1:80000 alcalinizada con bicarbonato de sodio al 8,4 % sobre el bloqueo del nervio dentario inferior. Material y métodos: Estudio experimental, prospectivo y longitudinal conformado por 50 pacientes de la Facultad de Odontología de la Universidad Nacional Mayor de San Marcos. Las siguientes soluciones fueron administradas para el bloqueo del nervio dentario inferior: lidocaína 2 por ciento con adrenalina 1:80000 alcalinizada con bicarbonato de sodio al 8,4 por ciento y lidocaína 2 por ciento con adrenalina 1:80000 no alcalinizada. Se evaluó la intensidad del dolor por la inyección, parámetros hemodinámicos y periodos anestésicos (tiempo de inicio de acción y duración del efecto anestésico). Resultados: Se evidenció una menor intensidad del dolor por la inyección en el grupo de lidocaína alcalinizada (19,16 ± 2,7) en comparación al grupo de lidocaína no alcalinizada (22,88 ± 4,2); p=0,02. Así mismo, el tiempo de inicio de acción fue menor en el grupo de lidocaína alcalinizada (105,72 ± 9,7s) en comparación con el grupo de lidocaína no alcalinizada (157,52 ± 12,1); p=0,002. Sin embargo, no se evidenciaron diferencias significativas en los parámetros hemodinámicos (p>0,05) y la duración del efecto anestésico (p=0,114). Conclusiones: La lidocaína 2 por ciento con adrenalina 1:80000 alcalinizada con bicarbonato de sodio al 8,4 por ciento sobre el bloqueo del nervio dentario inferior produce una disminución de la intensidad del dolor por la inyección y del tiempo de inicio de acción, en comparación con la formulación no alcalinizada. Sin embargo, no se evidencian diferencias en relación con los parámetros hemodinámicos ni a la duración del efecto anestésico(AU)
Introduction: The alkalinization of lidocaine has been successful in blocking the inferior dental nerve; however, there are contradictory results regarding its clinical efficacy. Objective: To determine the effect of 2 percent lidocaine with 1: 80,000 adrenaline alkalinized with 8.4 percent sodium bicarbonate on inferior dental nerve block. Material and methods: Experimental, prospective and longitudinal study that comprised 50 patients from the Dental School of the National University of San Marcos. The following solutions were administered for inferior dental nerve block: 2 percent lidocaine with epinephrine 1: 80,000 alkalinized with 8.4 percent sodium bicarbonate and 2 percent lidocaine with 1: 80,000 adrenaline not alkalinized. Pain intensity was evaluated by injection, hemodynamic parameters and anesthetic periods (time of onset of action and duration of the anesthetic effect). Results: There was a lower pain intensity due to injection in the alkalized lidocaine group (19.16 ± 2.7) compared to the non-alkalinized lidocaine group (22.88 ± 4.2); p=0.02. Likewise, the onset time of action was lower in the alkalized lidocaine group (105.72 ± 9.7) compared to the non-alkalinized lidocaine group (157.52 ± 12.1); p=0.002. However, no significant differences were found in the hemodynamic parameters (p>0.05) and the duration of the anesthetic effect (p=0.114). Conclusions: Lidocaine 2 percent with adrenaline 1: 80,000 alkalized with sodium bicarbonate at 8.4 percent on the block of the inferior dental nerve produces a decrease in pain intensity due to injection and the time of onset of action, compared to the non-alkalinized formulation. However, there are no differences in relation to the hemodynamic parameters or the duration of the anesthetic effect(AU)
