ABSTRACT

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.


Resumen Introducción: El uso de la infusión de lidocaína endovenosa ha aumentado en la última década como parte de un enfoque analgésico multimodal en los adultos; sin embargo, se dispone de información limitada sobre su seguridad y tolerabilidad en la población pediátrica. Métodos: Se presentan once casos de manejo de dolor agudo con lidocaína en infusión tratados en unidad de cuidado intensivo pediátrico. Resultados: Cinco casos fueron postoperatorio abdominal y seis casos tenían dolor abdominal no postoperatorio. Dos pacientes tenían cáncer y cursaban con colitis neutropénica. El control analgésico alcanzado fue bueno. Conclusión: Las infusiones de lidocaína parecen ser una opción segura para el manejo del dolor agudo ya sea posquirúrgico o no en la población pediátrica.

ABSTRACT

Objetivo: Evaluar la seguridad ocular y sistémica de una combinación de lidocaína 2 por ciento y fenilefrina 1 por ciento administrada por vía intracameral para provocar midriasis intraoperatoria en la cirugía de catarata. Métodos: Se realizó un estudio prospectivo de serie de casos en 70 ojos de igual número de pacientes sometidos a facoemulsificación con implante de lente intraocular. El grupo midriasis intraoperatoria en la cirugía lo conformaron 35 pacientes dilatados con una inyección intracameral de lidocaína y fenilefrina antes de la cirugía, mientras otros 35 ojos se dilataron de manera tradicional, con un colirio midriático previo. Para la seguridad ocular se evaluaron múltiples parámetros del examen oftalmológico pre- y posoperatorio. Resultados: La presión intraocular, el espesor corneal central, la densidad celular del endotelio corneal y el edema corneal posoperatorio como hallazgo del segmento anterior se comportaron de manera similar en ambos grupos de estudio. Se reportó una complicación transoperatoria en el grupo de manera tradicional y un caso con edema quístico macular posoperatorio en el grupo midriasis intraoperatoria en la cirugía que no representaron diferencias significativas. Conclusión: La inyección de lidocaína más fenilefrina intracameral es una opción segura tanto ocular como sistémica para provocar midriasis durante la facoemulsificación(AU)


Objective: Evaluate the ocular and systemic safety of a combination of 2 percent lidocaine and 1 percent phenylephrine administered intracamerally to achieve intraoperative mydriasis in cataract surgery. Methods: A prospective study was conducted of a case series of 70 patients (70 eyes) who underwent phacoemulsification with intraocular lens implantation. The intraoperative mydriasis group was composed of 35 patients dilated with an intracameral injection of lidocaine and phenylephrine before surgery, whereas another 35 eyes were dilated by the conventional method, with mydriatic eye drops. Ocular safety evaluation was based on the analysis of a wide variety of pre- and postoperative ophthalmological examination parameters. Results: Intraocular pressure, central corneal thickness, corneal endothelial cell density and postoperative corneal edema as an anterior segment finding, behaved in a similar manner in both study groups. An intraoperative complication was reported in the conventional method group and a case with postoperative cystoid macular edema in the intraoperative mydriasis group group, neither of them exhibiting significant differences. Conclusion: Intracameral lidocaine plus phenylephrine injection is a safe ocular and systemic option to achieve mydriasis during phacoemulsification(AU)

ABSTRACT

El bloqueo del nervio peri prostático con lidocaína, proporciona un buen alivio del dolor en la realización de la biopsia prostática guiada por ultrasonido, pero el dolor post-procedimiento, puede llegar a ser significativo, la adición del supositorio de diclofenac, podría proporcionar alivio adicional. Se asignaron al azar pacientes en 2 grupos el grupo 1 bloqueo con lidocaína del plexo peri prostático + supositorio de diclofenac sódico y el grupo 2 bloqueo con lidocaína del plexo peri prostático + supositorio de placebo, realizando biopsia doble sextante, el dolor a varios intervalos después del procedimiento se registró en una escala visual análoga (EVA) de 0 a 10. Los 2 grupos fueron similares en cuanto a edad, volumen de próstata, antígeno prostático específico, diagnóstico histopatológico. Los pacientes que recibieron diclofenac tuvieron puntajes de dolor significativamente más bajos que los que recibieron placebo (2 frente a 3,35) p 0,02. La administración rectal de diclofenac antes de la realización de la biopsia de próstata es un procedimiento simple que alivia significativamente el dolor experimentado sin aumento en la morbilidad(AU)


The peri-prostatic nerve block with lidocaine, provides good pain relief in performing ultrasoundguided prostate biopsy, but the postprocedure pain can be significant, the addition of diclofenac suppository, could provide additional relief. Patients were randomly assigned in 2 groups to group 1 blockade with lidocaine of the prostatic peri plexus + suppository of diclofenac sodium and group 2 blockade with lidocaine of the prostatic peri plexus + placebo suppository, performing double sextant biopsy, pain at several intervals after the procedure was recorded on a visual analog scale (EVA) from 0 to 10. Thee 2 groups were similar in terms of age, prostate volume, prostate-specific antigen, histopathological diagnosis. Patients who received diclofenac had pain scores significantly lower than those who received placebo (2 vs. 3.35) p 0.02. Rectal administration of diclofenac before performing a prostate biopsy is a simple procedure that relieves significantly pain experienced without increased morbidity(AU)

ABSTRACT

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)

ABSTRACT

Objetivou-se avaliar o bloqueio sensitivo e motor da administração peridural de 0,2mL/kg de duas concentrações de ropivacaína em comparação à lidocaína em cães. Utilizaram-se 24 cães, distribuídos em quatro grupos: NaCl a 0,9% (GS), lidocaína a 2% (GL), ropivacaína a 0,5% (GR5) e ropivacaína a 0,75% (GR7,5). Avaliaram-se a presença de movimentação espontânea, deambulação, sensibilidade superficial e profunda nos momentos cinco, 10, 15, 20, 25, 30, 45, 60, 90, 120, 180, 240 e 300 minutos após peridural. O retorno à movimentação espontânea foi semelhante entre GL (42,50 ± 6,12) e GR7,5 (69,2 ± 58,9). O tempo para deambulação foi mais prolongado em GR7,5 (107,5 ± 79,3) que em GS (9,2 ± 3,8) e em GR5 (32,5 ± 20,9). O retorno da sensibilidade profunda foi maior em GR 7,5 (152,5 ± 89,2) que em GS (5,8 ± 2,0), GR5 (46,7 ± 46,3) e GL (52,5 ± 20,7). O tempo de retorno da sensibilidade superficial foi maior em GR7,5 (205,0 ± 129,3) que em GS (7,5 ± 2,7), GL (72,5 ± 19,9) e GR5 (97,5 ± 55,1). Apesar do retorno precoce da movimentação, ropivacaína 0,75% está relacionada a tempo prolongado de recuperação da função muscular e bloqueio sensitivo mais prolongado que lidocaína e ropivacaína 0,5%.(AU)


The aim of the present study was to evaluate the sensory and motor blockade of epidural 0.5% and 0.75% Ropivacaine or Lidocaine in dogs. Twenty-four dogs were distributed in four groups: 0.9% NaCl (GS), 2% lidocaine (GL), 0.5% ropivacaine (GR5) and 0.75% ropivacaine (GR7.5). Spontaneous movement, ability to walk, superficial, and deep pain response were assessed 5, 10, 15, 20, 25, 30, 45, 60, 90, 120, 180, 240 and 300 minutes after epidural. Time to return to spontaneous movement was similar between GL (42.50 ± 6.12) and GR7.5 (69.2 ± 58.9). Time to return to ambulation was longer in GR7.5 (107.5 ± 79.3) than in GS (9.2 ± 3.8) and GR5 (32.5 ± 20.9). Time to recover deep sensitivity was longer in GR 7.5 (152.5 ± 89.2) than in GS (5.8 ± 2.0), GR5 (46.7 ± 46.3) and GL (52.5 ± 20.7). Time to return superficial sensitivity was longer in GR7.5 (205.0 ± 129.3) when compared to GS (7.5 ± 2.7), GL (72.5 ± 19.9) and GR5 (97.5 ± 55.1). Despite the early return of spontaneous movement, 0.75% ropivacaine is related to longer periods for muscle function recovery and longer sensory block than lidocaine and 0.5% ropivacaine.(AU)

ABSTRACT

INTRODUCCIÓN: Uno de los mayores intereses en el campo de la salud y en torno a la pandemia de COVID-19 es el desarrollo de estrategias para reducir la transmisión de la infección por SARS-CoV-2, incluyendo la protección de los trabajadores de salud, grupo de riesgo frente a la infección por este virus (Ng et al. 2020). La extubación es un procedimiento generador de aerosoles debido a la respuesta refleja del sistema respiratorio durante esta actividad, manifestada como la presencia de tos en algunos pacientes a los que se les realiza destete del ventilador mecánico (Brewster et al. 2020). Realizar la extubación requiere la proximidad de los trabajadores de salud con los pacientes, los cuales, incluyendo los casos de pacientes con COVID-19, suelen seguir siendo infecciosos al momento de la extubación (Brewster et al. 2020, Zhou et al. 2020, Ng et al. 2020), por lo que realizar esta actividad incrementaría la probabilidad de transmisión de esta infección viral. Ante ello, diversos grupos relacionados a la anestesiología señalan como útil el empleo de medicación que reduzca la generación de tos durante la extubación, que, junto a otras medidas de protección, disminuiría la probabilidad de transmisión de la infección por SARS-CoV-2 (Brown et al. 2020, Cook et al. 2020, D'Silva et al. 2020, Tan Li et al 2020). En EsSalud, se dispone de lidocaína y fentanilo, medicamentos descritos en la literatura científica como útiles para reducir la tos en pacientes a los que se les realizará el destete de la ventilación mecánica. Sin embargo, algunos especialistas argumentan que estos agentes sedantes podrían causar depresión respiratoria, retraso en el despertar e incrementar el riesgo de delirio si son administrados por periodos largos. Adicionalmente, los especialistas argumentan que dexmedetomidina es una alternativa que ofrecería la ventaja un despertar más rápido y una menor incidencia de delirio, además de reducir la incidencia de tos durante la extubación, estos efectos facilitarían la extubación del paciente y disminuiría la transmisión del SARS-CoV-2 al equipo médico tratante en la UCI. En ese sentido, el presente documento tuvo como objetivo evaluar la eficacia y seguridad de dexmedetomidina comparado con lidocaína y fentanilo para destete de ventilación mecánica invasiva en pacientes con COVID-19. TECNOLOGÍA DE INTERÉS: Dexmedetomidina es un agonista selectivo de los receptores alfa-2 con efectos ansiolíticos, sedantes (mediados por la inhibición del locus coeruleus, el núcleo noradrenérgico predominante, situado en el tronco cerebral) y analgésicos, produciendo además un efecto simpaticolítico al disminuir la liberación de noradrenalina en las terminaciones nerviosas simpáticas. METODOLOGÍA: Se buscó la evidencia disponible al 24 de agosto del 2020 en las siguientes bases de datos bibliográficas: PubMed, The Cochrane Library y LILACS. Asimismo, se realizó una búsqueda en sitios web pertenecientes a grupos que realizan evaluaciones de tecnologías sanitarias y guías de práctica clínica, incluyendo: The Canadian Agency for Drugs and Technologies in Health (CADTH), Scottish Medicines Consortium (SMC), The National Institute for Health and Care Excellence (NICE), Institute for Quality and Efficiency in Healthcare (IQWiG), Haute Authorité de Santé (HAS), Institute for Clinical and Economic Review (ICER) y el portal BRISA (Base Regional de Informes de Evaluación de Tecnologías en Salud de las Américas). Adicionalmente, se realizó búsqueda de evidencia en sitios web de organizaciones internacionales en anestesiología o de instituciones que estén desarrollando protocolos para el manejo de pacientes con COVID-19. RESULTADOS: En la búsqueda de la evidencia no se identificaron estudios que evalúen la eficacia y seguridad de dexmedetomidina, comparado con lidocaína y fentanilo, para el destete de ventilación mecánica invasiva, en pacientes con COVID-19. Sin embargo, se identificaron: tres GPC o consensos de expertos elaborados por la Safe Airway Society, Alfred ICU y la Difficult Airway Society e instituciones colaboradoras; una RS con metaanálisis en red realizada por Tung et al., así como dos ensayos clínicos controlados, aleatorizados (ECA) que no fueron incluidos en la RS. Se debe precisar que esta RS y estos ECA no fueron realizados en la población de interés del presente reporte breve (pacientes con COVID-19); por lo que fueron incluidos como evidencia indirecta. CONCLUSIONES: En el presente documento, se evaluó la mejor evidencia científica disponible hasta la actualidad sobre eficacia y seguridad de dexmedetomidina comparado con lidocaína y fentanilo para destete de ventilación mecánica en pacientes con COVID-19. Se encontraron: tres GPC o consensos de expertos, una RS y dos ECA. La RS y los ECA incluidos aportan al reporte breve como evidencia indirecta; al no haber sido desarrollados en pacientes con COVID-19. Las guías de la Safe Airway Society (SAS), Alfred ICU y de la Difficult Airway Society (DAS) e instituciones colaboradoras que fueron elaboradas para dar recomendaciones para el proceso de extubación en pacientes con COVID-19, hacen mención a dexmedetomidina (SAS, Alfred ICU), opioides como el fentanilo (SAS y DAS) y la lidocaína (SAS, DAS) para reducir la tos durante el proceso de extubación, aunque precisan la ausencia de evidencia sobre el uso de este medicamentos en pacientes con COVID-19, señalando que se debe evaluar el balance riesgo-beneficio para el uso de los mismos. En general, las recomendaciones descritas en estos documentos proceden de consensos por opinión de expertos, y no establecen una preferencia de un medicamento sobre los otros. En cuanto a los resultados de la RS con MA en red de Tung et al., y los ECA de Kothari et al., y Hu et al., no han podido encontrar evidencia que apoye la hipótesis que el efecto de la dexmedetomidina sea superior al de lidocaína y fentanilo sobre el manejo de la tos (esto es, no se encontraron diferencias entre estos). Estos resultados deben ser interpretados con cautela debido a que la población de estudio de los mismos no son pacientes COVID-19. No obstante, la información que proporcionan puede ayudar a tener una idea del efecto que se podría esperar con el uso de cada uno de los medicamentos mencionados, tanto en eficacia como en seguridad. Al respecto, frente a una ausencia de diferencia entre dexmedetomidina en comparación con lidocaína y fentanilo, se tiene evidencia que la primera tiene un mayor riesgo de bradicardia que los dos últimos. Esto se condice con la literatura previa acerca de dicho medicamento (dexmedetomidina), donde además se describe que los adultos mayores y personas con comorbilidades presentan una mayor proporción de eventos de bradicardia atribuibles al uso de dexmedetomidina lo que, siendo que estos grupos poblacionales son los más afectados por COVID-19, sería esperable una mayor presencia de bradicardia como evento adverso en pacientes con COVID-19 que reciben dexmedetomidina, lo que llama a la precaución cuando se considera el uso de esta tecnología en estos pacientes. De este modo, la mejor evidencia disponible a la fecha (24 de agosto del 2020), procedente de tres GPC o consensos de expertos, una RS con metaanálisis en red y dos ECA, apunta a que el balance de riesgo-beneficio del empleo de dexmedetomidina comparado con el uso de lidocaína o fentanilo, en la reducción de la tos durante el destete de ventilación mecánica en pacientes con COVID-19 es de alta incertidumbre, especialmente por el hecho que la dexmedetomidina está asociada a un mayor riesgo de reacciones adversas frente a los otros dos medicamentos, especialmente en lo referente a bradicardia. Por ello, con este cuerpo de evidencia, el IETSI no ha encontrado sustento técnico que pueda apoyar una recomendación a favor del uso de dexmedetomidina por sobre el de lidocaína o fentanilo en pacientes COVID-19 para reducir la tos al momento de la extubación.

ABSTRACT

Se realizó un ensayo clínico controlado simple ciego con el objetivo de evaluar la respuesta hemodinámica post intubación orotraqueal y efectos adversos con clonidina versus lidocaína en pacientes sometidos a cirugía abdominal electiva con anestesia general en el Hospital Central Universitario Dr. Antonio María Pineda durante el período mayo ­ agosto de 2018. Cincuenta pacientes conformaron la muestra distribuidos aleatoria y equitativamente en dos grupos: el grupo A recibió clonidina a una dosis de 1.5 mcg/kg endovenoso, 20 minutos previos a la inducción anestésica y el grupo B recibió lidocaína a una dosis de 1.5 mg/kg, 90 segundos previos a la inducción anestésica. La edad promedio de los pacientes varió entre 31,6 ± 12,2 años de edad, con predominio del sexo femenino. Los efectos adversos fueron hipotensión al minuto y tres minutos post intubación; sólo dos pacientes del grupo A presentaron bradicardia a los tres minutos. Se observó una diferencia estadísticamente significativa entre ambos grupos en relación a la presión arterial sistólica, diastólica y media y frecuencia cardíaca inmediatamente posterior a la intubación, al minuto y a los tres minutos. Estos resultados confirman que el uso de clonidina es eficaz para atenuar la respuesta hemodinámica posterior a la intubación en pacientes sometidos a cirugía abdominal electiva bajo anestesia general(AU)


A single-blind controlled clinical trial was carried out with the aim to evaluate the hemodynamic response after orotracheal intubation in patients that receive clonidine or lidocaine in patients undergoing elective abdominal surgery with general anesthesia at the Hospital Central Universitario Dr. Antonio María Pineda during the period May - August 2018. Fifty patients were distributed randomly and equitably in two (2) groups: group A received clonidine in a dose of 1.5 mcg/kg intravenously, 20 minutes before anesthetic induction and group B received lidocaine at a dose of 1.5 mg/kg, 90 seconds before anesthetic induction. Median age of patients was 31.6 ± 12.2 years with a predominance of female sex. Most common adverse effect was hypotension in both groups at one and three minutes post intubation; only two patients in the clonidine group showed bradycardia at three minutes. There was a statistical significant difference between both groups in regards to the mean values of systolic, diastolic and mean arterial pressure and heart rate at all time points measured after intubation. These results confirm that clonidine is effective in reducing hemodynamic response after intubation in patients that undergo elective abdominal surgery under general anesthesia(AU)

ABSTRACT

Abstract Objective: To investigate the effects of lidocaine oropharyngeal spray applied before endotracheal intubation on hemodynamic responses and electrocardiographic parameters in patients undergoing coronary artery bypass grafting. Methods: A total of 60 patients who underwent coronary artery bypass grafting surgery were included in this prospective randomized controlled study. Patients were randomly divided into two groups, the topical lidocaine group (administration of 10% lidocaine oropharyngeal spray, five minutes before laryngoscopy and endotracheal intubation) and the control group. Both groups were compared with each other in terms of main hemodynamic parameters including mean arterial pressure and heart rate, as well as P and QT wave dispersion durations, before and after endotracheal intubation. Results: The groups were similar in terms of age, gender, and other demographics and basic clinical characteristics. There was a statistically significant difference between the groups in terms of QT dispersion durations after laryngoscopy and endotracheal intubation. The increase in QT dispersion duration was not statistically significant in the topical lidocaine group, whereas the increase in QT dispersion duration was statistically significant in the control group. When the groups were compared in terms of P wave dispersion durations, there were significant decreases in both groups, but there was no significant difference between the groups. Conclusion: Our study revealed that the topical lidocaine administration before endotracheal intubation prevented increase of QT dispersion duration in patients undergoing coronary artery bypass grafting. Trial Registration: NCT03304431

ABSTRACT

RESUMEN Objetivo: Evaluar la eficacia de una combinación de lidocaína 2 por ciento y fenilefrina 1 por ciento administrada intracameralmente para provocar midriasis intraoperatoria en la cirugía de catarata. Métodos: Realizamos un estudio prospectivo, comparativo, de serie de casos en 70 ojos de igual número de pacientes quienes fueron sometidos a cirugía de catarata mediante facoemulsificación con implante de lente intraocular, en el Instituto Cubano de Oftalmología "Ramón Pando Ferrer" entre septiembre del año 2017 y febrero de 2018. 35 pacientes fueron dilatados con una combinación de fenilefrina y lidocaína inyectada en la cámara anterior justo antes de la cirugía (grupo midriáticos intracamerales) y otros 35 ojos se dilataron con un colirio midriático como se realiza cotidianamente y de manera tradicional (grupo midriáticos tópicos). La eficacia se evaluó mediante la medición del diámetro pupilar (pupilometría) realizada con un compás quirúrgico en diferentes momentos de la cirugía en ambos grupos de estudio. Los resultados de ambos grupos se compararon entre sí. Resultados: En ambos grupos de pacientes se lograron diámetros pupilares superiores a los 7 mm justo antes de la capsulorrexis, aunque fueron ligeramente mayor en el grupo midriáticos tópicos (8,17 vs. 7,55 mm). En las mediciones posteriores todas las pupilometrías del grupo midriáticos intracamerales fueron superiores y se mantuvieron por encima de los 7 mm, mientras las del grupo midriáticos tópicos sufrieron una reducción paulatina hasta el final de la cirugía (5,68 mm). Conclusiones: La combinación de lidocaína más fenilefrina aplicada de manera intracameral es efectiva para provocar una midriasis adecuada y mantenida durante la cirugía de catarata(AU)


ABSTRACT Objective: Evaluate the efficacy of the combination 2 percent lidocaine / 1 percent phenylephrine administered intracamerally to achieve intraoperative mydriasis in cataract surgery. Methods: A prospective comparative study was conducted of a case series of 70 patients (70 eyes) who underwent cataract surgery by phacoemulsification with intraocular lens implantation at Ramón Pando Ferrer Cuban Institute of Ophthalmology from September 2017 to February 2018. Of the total eyes, 35 were dilated with a combination of phenylephrine and lidocaine injected into the anterior chamber just before surgery (MIC group), whereas the remaining 35 were dilated with mydriatic eye drops in the habitual traditional manner (MT group). Efficacy was evaluated in the two study groups measuring the pupil diameter (pupilometry) with a surgical compass at several moments during the surgery. The results for each group were compared. Results: In both groups patients achieved pupil diameters above 7 mm just before capsulorhexis, though values were slightly higher in the MT group (8.17 vs. 7.55 mm). Later measurement showed that in the MIC group all pupilometries were higher, remaining above 7 mm, whereas in the MT group they underwent gradual reduction until the end of surgery (5.68 mm). Conclusions: The combination of lidocaine and phenylephrine administered intracamerally is effective to achieve appropriate, sustained mydriasis during cataract surgery(AU)

ABSTRACT

Introducción: El paraganglioma es un tumor neuroendocrino poco frecuente que surge de los paraganglios autonómicos extraadrenales en diversos lugares del organismo. También se les conoce como feocromocitomas extraadrenales. Alrededor de 90 por ciento son benignos y se curan mediante la extirpación quirúrgica, el restante 10 por ciento son malignos, y pueden provocar metástasis a distancia. El diagnóstico es importante por su riesgo de malignidad, por las implicaciones de otras neoplasias asociadas y dada la posibilidad de realizar estudios genéticos para la detección de otros casos dentro de una misma familia. Objetivo: Exponer aspectos clínico-epidemiológicos de esta enfermedad y las implicaciones perioperatorias concernientes a la conducta anestésica perioperatoria de estos pacientes. Caso clínico: Paciente femenina, de 56 años de edad con antecedentes de hipertensión arterial de más dos años de evolución y difícil control, diabetes mellitus e historia de cefalea, palpitaciones y sensación de calor. Diagnóstico imagenológico de una masa pararrenal sospechosa de paraganglioma que se confirmó por estudio histopatológico posterior a la exceresis. Conclusiones: La técnica anestésica para la resección de estos tumores es un desafío importante para el anestesiólogo que debe enfrentar dicha intervención quirúrgica, planteándose los riesgos de las etapas pre-, intra- y posoperatoria(AU)


Introduction: Paraganglioma is a rare neuroendocrine tumor that emerging from the extra-adrenal autonomic paraganglia and it may occur in several parts of the body. Paraganglioma is also named extra-adrenals pheochromocytomas. Roughly 90 percent of these tumors are benign and can be excised through surgery whereas 10 percent of them are malignant and cause distant metastasis. Paragangliomas are closely linked to pheochromocytomas because they cannot be differentiated at cell level and often share the same clinical manifestations such as hypertension, episodic headache, sweating and tachycardia. The diagnosis of these tumors is important because of risk of becoming malignant, the implications of other related neoplasias and the possibility of making genetic studies to detect other cases in the same family. Objective: To expose about epidemiology, clinical manifestations, diagnostic tests and perioperative management of these tumors by a presentation of a clinical case. Case Report: Female 56 years old, clinical history of 2 years of uncontrolled hypertension, diabetes mellitus, who presented with headache, palpitations and feeling of warm. She was diagnosed with a pararrenal mass suspected of paraganglioma associated with catecholamine hypersecretion, confirmed by histopathology. Conclusions: The treatment of these tumors requires a more complete surgical resection possible since the prognosis depends. Surgical management of pheochromocytoma needs special perioperative requirements. The anesthesiologist must observe this surgery, establish the risks of the phase pre-intra and postoperative(AU)

ABSTRACT

Abstract Introduction Posttonsillectomy pain results in significant morbidity to the patients. There is a disagreement in the literature regarding the use of local anesthetics during tonsillectomy. The aim of this placebo-controlled, double-blind study is to evaluate the effect of peritonsillar administration of local anesthetics. Objective To evaluate the role of intraoperative use of analgesics in tonsillar fossa and postoperative evaluation with visual analogue scale (VAS) scores in achieving pain relief after tonsillectomy procedure Methods In this study, 180 patients were randomized to 1 of the 6 groups: bupivacaine infiltration, lidocaine infiltration, normal saline infiltration, bupivacaine packing, lidocaine packing, and normal saline packing. Pain caused by speaking, swallowing, and on rest was assessed using VAS at 4, 8, 12, 16 hours, and at discharge. Results Significant analgesia was obtained in patients who received bupivacaine infiltration and packing compared with placebo (p < 0.05). The majority of the study subjects had no postoperative complications, and patients receiving bupivacaine infiltration required less additional analgesics in the first 24 hours after surgery. Conclusion We advocate the use of bupivacaine infiltration or packing immediately following the procedure to achieve adequate postoperative analgesia.

ABSTRACT

O objetivo deste estudo foi avaliar os efeitos analgésicos transoperatórios da infusão contínua de morfina e cetamina, associada ou não à lidocaína, em gatas submetidas à OSH eletiva. Foram utilizadas 16 fêmeas adultas, hígidas, pré-medicadas com acepromazina (0,1mg/kg) e morfina (0,5mg/kg), ambas pela via intramuscular, induzidas com cetamina (1mg/kg) e propofol (4mg/kg), pela via intravenosa, e mantidas sob anestesia geral inalatória com isoflurano a 1,4 V%. Os animais foram alocados aleatoriamente em dois grupos: grupo morfina, lidocaína e cetamina (MLK, n=8), que recebeu bolus de lidocaína (1mg/kg), pela via IV, seguido de infusão de morfina, lidocaína e cetamina (0,26mg/kg/h, 3mg/kg/h e 0,6mg/kg/h, respectivamente); e grupo morfina e cetamina (MK, n=8), que recebeu bolus de solução salina, seguido de infusão de morfina e cetamina, nas mesmas doses do MLK. Os momentos avaliados foram: M0, basal, cinco minutos após a indução; M1, imediatamente após a aplicação do bolus de lidocaína ou solução salina; M2, M3, M4 e M5, a cada cinco minutos, até completar 20 minutos do início da infusão; M6, após a incisão da musculatura; M7, após pinçamento do primeiro pedículo ovariano; M8, após pinçamento do segundo pedículo ovariano; M9, após pinçamento da cérvix; M10, após sutura da musculatura; M11, ao final da cirurgia; e M12, M13 e M14, intervalos de cinco minutos, até completar uma hora de infusão. A FP no M0 foi maior no MLK quando comparado ao MK. Em ambos os grupos, a PAS foi maior no M7 e no M8 em relação ao M0, porém no MK, além da PAS, a FP foi maior do M7 ao M13, assim como a f. Os animais do MK necessitaram de um número maior de resgates transoperatorios, total de 23, do que o MLK, total de sete. Conclui-se que a adição de lidocaína incrementou a analgesia oferecida, reduzindo o número de resgates analgésicos transoperatórios, a dose total de fentanil, bem como a probabilidade de os animais necessitarem dese tipo de resgate.(AU)


The aim of this study was to evaluate the trans-operative analgesics, continuous infusion of morphine and ketamine, with or without lidocaine in cats undergoing elective OSH. Sixteen adult cats were used, otherwise healthy, pre-medicated with acepromazine (0.1mg/kg) and morphine (0.5mg/kg), both intramuscularly, induced with ketamine (1mg/kg) and propofol (4mg/kg), intravenous, maintained under general inhalation anesthesia with isoflurane 1.4 V%. The animals were randomly allocated into two groups: morphine, lidocaine and ketamine (MLK, n= 8), which received intravenous bolus of lidocaine (1mg/kg) followed by infusion of morphine, lidocaine and ketamine (0.26mg / kg/h, 3mg / kg/h and 0.6mg / kg/h, respectively); Morphine and ketamine (MK, n= 8), who received bolus of saline followed by infusion of morphine and ketamine at the same doses of MLK. The evaluated moments were: M0, basal, 5 minutes after induction; M1 immediately after the application of lidocaine bolus injection or saline; M2, M3, M4 and M5, every 5 minutes to complete 20 minutes after the start of infusion; M6, after the incision of the musculature; M7, after clamping of the first ovarian pedicle; M8, after clamping of the second ovarian pedicle; M9, after clamping of the cervix; M10, after suturing of the musculature; M11, at the end of surgery; And M12, M13 and M14, 5 minute intervals until completing one hour of infusion. The time to extubating and full recovery of animals, and the need for rescue analgesic fentanyl intraoperatively were also evaluated. HR in M0 was higher in MLK when compared to MK. In both groups the SBP was higher in M7 and M8 compared to M0, but the MK, addition of SAP, HR was greater M7 to M13, as well as f. MK animals required a greater number of trans-operative rescues than the MLK. It was concluded that the addition of lidocaine to the protocol using morphine and ketamine increased its analgesia.(AU)

ABSTRACT

Abstract Periodontal therapy usually requires local anesthesia. If effective, a non-invasive, liposomal anesthetic gel could increase the levels of acceptance of patients in relation to periodontal therapy. Objective: This study investigated the efficacy of liposomal anesthetic gel for pain control during periodontal therapy. Methodology: Forty volunteers with moderate to severe chronic periodontitis were recruited, of which at least three sextants required periodontal therapy. At least one of the selected teeth had one site with a probing depth of ≥4 mm. The volunteers received the following three gels: a placebo, lidocaine/prilocaine (Oraqix®), or a liposomal lidocaine/prilocaine, which were applied to different sextants. Pain frequency was registered during treatment and the volunteers received a digital counter to register any painful or uncomfortable experiences. At the end of each session, the volunteers indicated their pain intensity using rating scales (NRS-101 and VRS-4). The volunteers had their hemodynamic parameters measured by a non-invasive digital monitor. Results: Pain frequency/intensity did not show statistical difference between intervention groups. The tested gels did not interfere with the hemodynamic indices. Dental anxiety, suppuration and probing depth could influence pain during periodontal therapy. Conclusion: Our results suggest limited indications for the use of non-invasive anesthesia when used for scaling and root planing. Intra-pocket anesthetic gel could be a good option for anxious patients, or those who have a fear of needles.

ABSTRACT

Abstract The nucleus accumbens shell (NAcSh) plays a role in appetitive and negative motivation with sex differences in responses. NAcSh and its laterality in metabolic and hormonal responses to chronic stress in female rats is evaluated via transient inactivation of this nucleus during stress induction. Animals in the stress groups received consecutive stress for four days and transient inactivation of NAcSh was performed by administrating lidocaine (0.2%) unilaterally or bilaterally in the nucleus for five minutes before electric foot shock induction. After stress termination, food and water intake, latency to eat, plasma glucose, corticosterone, estradiol and progesterone were measured in all groups. Results showed that stress increased food intake and blood glucose level, but there were no change in the latency to eat and the amount of water intake. The right side, the left side, and both sides of NAcSh may be dominant in latency to eat, food intake, and both water intake and plasma glucose level, respectively. Although chronic stress included no changes for corticosterone and progesterone, it increased estradiol level in plasma. Also, bilateral and right sides of NAcSh may have modulatory effects on stress in corticosterone and progesterone, respectively, without affecting estradiol. It can be concluded that the NAc shell plays a pivotal role in metabolic and hormonal responses to chronic stress in a laterality manner in female rats.

ABSTRACT

Background: Local anaesthesia usage and wastage are common in the operation rooms. The wastage is often not given due considerations. Budgetary allocation for drugs is an identifiable area for cost-cutting and savings. Hence, the need to minimize wastage Objectives: To assess and estimate the amount of local anaesthesia usage and wastage in the labour ward theatre. Also, to analyze the financial implications of the wastages and suggest appropriate steps to reduce the wastages. Methodology: A prospective observational study conducted in the labour ward theatre of a tertiary care hospital. The amount of local anaesthesia administered to the patient during spinal anaesthesia prior to caesarean section was considered the dose used. The wastage was considered as the amount of local anaesthetic agents left unutilized in the syringes, ampules or vials after completion of each caesarean delivery. An estimation of the cost of wasted local anaesthetic agents was made. Result: The local anaesthetic agents being used in significant quantities were hyperbaric bupivacaine, plain lidocaine and lidocaine with adrenaline. The wastage was found more during the use of hyperbaric bupivacaine as the cost of its wastage formed the bulk (N75,000.00/ $210.10) of the estimated total cost of wasted local anaesthetic agents during the study period which was N88, 100.00 ($246.77). Conclusion: There were appropriate uses of the local anaesthesia with respect to the choice and doses for caesarean deliveries but there were wastages often ignored as infinitesimal. In the long run, the wastages become significant and the financial implication scale up the burden of health bills. Effective waste reduction strategies have input in the overall reduction of financial burden associated with health care. Emphasis should be t ailored towards awareness of these wastages among resident doctors and their prudent use of local anaesthesia

ABSTRACT

Background: A patient is required to be fully relaxed and airway reflexes should be adequately suppressed to allow for smooth insertion of a laryngeal mask airway (LMA).Propofol and a variety of other induction agents and their combinations have been tried to ease its insertion. The use of cheaper alternatives in our environment is highly desirable. Aims and objectives: To compare the ease of insertion of LMA in patients given propofol alone versus thiopentone with lignocaine, as well as assessing the cost effectiveness of these agents in our hospital setting. Methods: This is arandomised single blind prospectivestudy carried out in a Public Tertiary Academic Health Institution. Sixty-four ASA I and II patients equally randomized into 2 groups scheduled for short (not lasting more than one hour) elective gynaecological, orthopaedic, urological and general surgical procedures were recruited into this study. Patients were premedicated with 1g.kg-1 fentanyl intravenously and pre-oxygenated for five minutes. This was followed by an induction dose of either 2.5mg.kg-1propofol (group A) or a sequence of 2mg.kg-1 lignocaine and 5mg.kg-1thiopentone (group B) given by a trained assistant. With the patients in the sniffing position, LMA insertion was attempted immediately after induction of anaesthesia by the anaesthetist (researcher) who observed the ease of LMA insertion using presence or absence of adverse airway responses to LMA insertion such as coughing, gagging, laryngospasm, head and limb movement or inadequate jaw relaxation. These responses were graded as; no response, mild response, moderate response and severe response. Overall assessment of the ease of LMA insertion was then done combining these graded adverse airway responses as; excellent if there were no adverse airway responses, good if responses were mild, satisfactory if responses were moderate and poor if responses were severe with additional anaesthetic required to allow LMA insertion.Results: The average age in group A was 36.5±14 whereas in group B it was 38.7±05 with the p=0.493.There were 22 (56.4%) male patients in group A compared to 17 (43.6%) male patients in group B with p=0.528; whereas, there were 10 (40.0%) female patients in group A compared to 15 (60.0%) female patients in group B with p=0.326. Excellent LMA insertion were observed in 28 (87.5%) patients in group A compared to 27 (84.4%) patients in group B (P= 0.893); Good LMA insertion in 2 (6.3%) patients in group A compared to 1 (3.1%) patient in group B (p= 0.564); Satisfactory in 2 (6.3%) patients in group A compared to 4 (12.5%) patients in group B (p= 0.655).Conclusion: Thiopentone together with Lignocaine provided optimum conditions for laryngeal mask airway insertion comparable to that provided by propofol alone

ABSTRACT

Objetivou-se comparar os efeitos fisiológicos, analgésicos e sobre a taxa de infusão de propofol, decorrentes da anestesia epidural com lidocaína, associada ao tramadol ou à dexmedetomidina, em felinas submetidas à ovariosalpingohisterectomia (OSH). Para tal, 16 felinas hígidas foram pré-tratadas com acepromazina 0,08mg/kg/IM, utilizando-se propofol para a indução (dose-efeito) e manutenção anestésicas. Após indução, as gatas foram aleatoriamente distribuídas em dois grupos (n=8), designados: grupo lidocaína-tramadol (GLT), tratado com lidocaína (3,0mg/kg) associada ao tramadol (2,0mg/kg); e grupo lidocaína-dexmedetomidina (GLD), tratado com lidocaína (3,0mg/kg) associada à dexmedetomidina (2µg/kg), pela via epidural. Durante a OSH, a infusão de propofol foi aumentada ou reduzida, objetivando-se manutenção de plano anestésico cirúrgico. Foram avaliados os parâmetros: f, FC, SPO2, EtCO2, PAS, PAD, PAM, T°C, nos períodos pré (M1) e transoperatórios (M2 a M7); a taxa mínima de propofol necessária; o tempo de recuperação anestésica e a qualidade da analgesia pós-cirúrgica durante seis horas. Ambos os tratamentos garantiram baixas taxas mínimas de infusão de propofol, todavia o uso da dexmedetomidina resultou em bradicardia inicial, elevação da pressão arterial, maior tempo de recuperação e menor qualidade analgésica, quando comparada ao tramadol.(AU)


The aim of this study was to compare the physiological and analgesic effects and the minimum infusion rate of propofol of epidural anesthesia with lidocaine associated to tramadol or dexmedetomidine, in cats undergoing ovariosalpingohysterectomy (OSH). For this purpose, 16 healthy cats were pretreated with acepromazine (0.08mg kg -1 IM) and propofol was used for induction (dose-effect) and maintenance of anesthesia. After induction, the cats were assigned in two randomized groups (n= 8), named: Lidocaine-tramadol group (LTG), treated with lidocaine (3mg kg -1 ) associated to tramadol (2mg kg -1 ) and Lidocaine-dexmedetomidine group (LDG), treated with lidocaine (3mg kg -1 ) associated to dexmedetomidine (2g kg -1 ), by epidural route. During OSH, propofol infusion was increased or decreased, setting to maintain surgical anesthetic depth. The parameters f, HR, SPO 2 , EtCO 2 , SAP, DAP, MAP, T°C in the pre (M1) and trans-operative periods (M2 to M7); minimum infusion rate of propofol; time of anesthetic recovery and quality of postoperative analgesia during six-hour interval, were evaluated. Both protocols provided low minimum infusion rate of propofol. However, dexmedetomidine resulted in initial bradycardia, elevated blood pressure, longer recovery time, and lower analgesic quality when compared to tramadol.(AU)

ABSTRACT

Avaliou-se a recuperação anestésica e a analgesia residual da infusão contínua (IC) de fentanil (F), lidocaína (L), cetamina (K) e fentanil-lidocaína-cetamina (FLK), associados à anestesia total intravenosa com o propofol, em cadelas submetidas à ovariossalpingo-histerectomia. Foram utilizados 32 animais pré-medicados com acepromazina, distribuídos em quatro grupos de acordo com o tratamento analgésico: F: bolus de 0,0036mg/kg de fentanil e IC de 0,0036mg mg/kg/h; L: bolus de 3mg/kg de lidocaína e IC de 3mg/kg/h; K: bolus de 0,6mg/kg de cetamina e IC de 0,6mg/kg/h; e FLK: bolus e IC dos três fármacos nas doses supracitadas. Após o bolus do tratamento analgésico, foi realizada a indução e o início da IC do tratamento analgésico e do propofol. Para avaliação da recuperação anestésica, foram considerados os tempos de extubação, decúbito esternal, posição quadrupedal e os efeitos adversos. A avaliação da analgesia foi realizada por meio da escala visual analógica e modificada de Glasgow, durante seis horas. Os efeitos adversos observados foram vômito, sialorreia e tremor muscular. Receberam analgesia de resgate 100% dos animais do grupo F, 87,5% do K, 50% do L e 12,5% do FLK. O FLK demonstrou maior analgesia, e a recuperação anestésica foi semelhante em todos os grupos.(AU)


The anesthetic recovery and residual analgesia of continuous rate infusion (CRI) of fentanyl (F), lidocaine (L), ketamine (K) and fentanyl-lidocaine-ketamine (FLK) associated with total intravenous anesthesia with propofol in bitches submitted to ovariohysterectomy were evaluated. 32 animals were used, pre-medicated with acepromazine and distributed into four groups according to analgesic treatment: F loading dose (LD) of 0.0036mg/kg fentanyl, and CRI of 0.0036mg/kg/h, L: LD of 3mg/kg lidocaine, and CRI of 3mg/kg/h; K: LD of 0.6mg/kg ketamine, and CRI of 0.6mg/kg/h and FLK: LD and CRI of the three drugs in the above mentioned doses. After the LD of analgesic treatment, the induction was performed and the CRI of the analgesic treatment and propofol started. To evaluate the anesthetic recovery, the time of extubation, sternal decubitus, quadrupedal position and adverse effects were considered. The analgesia evaluation was performed using the visual scale and modified Glasgow for six hours. The adverse effects observed were vomiting, sialorrhea and muscle tremor. 100% of the animals in group F, 87.5% of K, 50% of L and 12.5% of FLK received rescue analgesia. FLK demonstrated greater analgesia, and anesthesia recovery was similar in all groups.(AU)
