    Full Text Available El citrato es un potente inhibidor de la cristalización de sales de calcio. La hipocitraturia es una alteración bioquímica frecuente en la formación de cálculos de calcio en adultos y especialmente en niños. El pH ácido (sistémico, tubular e intracelular es el principal determinante de la excreción de citrato en la orina. Si bien la mayoría de los pacientes con litiasis renal presentan hipocitraturia idiopática, hay un número de causas para esta anormalidad que incluyen acidosis tubular renal distal, hipokalemia, dietas ricas en proteínas de origen animal y/o dietas bajas en álcalis y ciertas drogas, como la acetazolamida, topiramato, IECA y tiazidas. Las modificaciones dietéticas que benefician a estos pacientes incluyen: alta ingesta de líquidos y frutas, especialmente cítricos, restricción de sodio y proteínas, con consumo normal de calcio. El tratamiento con citrato de potasio es efectivo en pacientes con hipocitraturia primaria o secundaria y en aquellos desordenes en la acidificación, que provocan un pH urinario persistentemente ácido. Los efectos adversos son bajos y están referidos al tracto gastrointestinal. Si bien hay diferentes preparaciones de citrato (citrato de potasio, citrato de sodio, citrato de potasio-magnesio en nuestro país solo está disponible el citrato de potasio en polvo que es muy útil para corregir la hipocitraturia y el pH urinario bajo, y reducir marcadamente la recurrencia de la litiasis renal.

    Full Text Available La cirugía en la población infantil representa una fuente de disconfort para el paciente y su entorno familiar que a menudo es infravalorado tanto por éstos como por los profesionales. Aún hay mucho por hacer para disminuir este impacto y proporcionar a los niños unas condiciones emocionales adecuadas para enfrentarse a la cirugía y al postoperatorio. El objetivo de este trabajo era demostrar la utilidad del citrato de fentanilo oral transmucosa (CFOT como medio de ansiolisis preoperatorio y analgesia postoperatoria. Para ello se administró previo a la intervención 10 ug/Kg de CFOT a un grupo de 45 niños sometidos a adenoamigdalectomía y se valoró el comportamiento, la colaboración y la analgesia obtenida en el antequirófano y postoperatorio inmediato. Los resultados obtenidos se compararon con los de un grupo control similar utilizando para ello la T de student y ANOVA, obteniéndose diferencias significativas en cuanto al grado de colaboración, ansiolisis y analgesia a favor del grupo CFOT. Nosotros sostenemos que este método es además seguro, sencillo y goza de una gran aceptación por parte de los padres y profesionales implicados en el proceso asistencial.The surgery in the paedriatic population represents a source of disconfort for the patient and his familiar surroundings that often are infravalued, so much by these as by the professionals. Still there is much to make to diminish this impact and to provide to the children emotional conditions adapted to face the surgery and the postoperative period. The objective of this work was to demonstrate the utility of fentanyl oral (CFOT to provide ansiolityc and postoperative analgesia. 10 ug/Kg of CFOT was administered previous to intervention to a group of 45 children submissive for amigdalectomy and the behavior was valued, the collaboration and the analgesia obtained in the immediate postoperative period.

    El alivio del dolor por medio de la acupuntura se desarrollo en la China moderna después de 1945 con la influencia inicial de la medicina occidental. Según la teoría tradicional, la acupuntura es eficaz sólo cuando las agujas producen el fenómeno “De Qi”, descrito como una sensación ligeramente dolorosa, relajante y si los dedos del acupuntor notan que las agujas son aspiradas por el punto tratado. En el Occidente diferentes estudios han demostrado que la acupuntura estimula fibras aferentes ...

    Full Text Available Objetivo: Valorar la eficacia analgésica y seguridad en el parto de Remifentanilo por vía intravenosa mediante un sistema de analgesia controlada por la paciente. Material y Método: El grupo de estudio lo componen 25 gestantes sanas, primigestas a término, con parto eutócico instaurado, que solicitan analgesia durante el trabajo de parto. Resultados: Se produce un alivio significativo del dolor desde la primera hora de tratamiento en todos los casos. La analgesia se mantiene hasta el final en el 80% de los casos. El 20% restante solicitó anestesia regional en el período expulsivo. Se produjo un grado de sedación de leve a moderado durante todo el estudio, que las pacientes valoraron positivamente. Solo en dos casos el grado de sedación fue moderado-severo, a pesar de lo cual las gestantes decidieron continuar en el estudio. No se registraron efectos adversos materno-fetales. Conclusiones: La analgesia del parto con Remifentanilo por vía intravenosa controlada por la paciente es un método efectivo y presenta un aceptable perfil de seguridad materno y fetal.Objective: To assess the analgesic efficacy of patient-controlled in-travenous analgesia with remifentanil and its potential side effects during labour. Method: We analyzed 25 healthy nulliparas at full term pregnancy, in established uncomplicated labour, who demanded pain relief. Results: All the patients experienced a significant pain relief during the first hour of treatment which was maintained on until delivery on 80%. The other 20% required additional regional anaesthesia at the end of second stage. The level of sedation was mild to moderate and treatment was well tolerated except for two, who presented heavy sedation. No maternal or neonatal side effects were registered. Conclusions: Patient-controlled intravenous analgesia with remifentanil is effective for labour pain relief and produces no major maternal and neonatal side effects.

    Full Text Available La cateterización de una vena central como acceso vascular para la hemodiálisis supone una alternativa rápida y segura, que permite ser utilizada inmediatamente y obtener flujos sanguíneos óptimos. Sin embargo, el uso de catéteres no está exento de complicaciones, lo que provoca una alta morbilidad aumentando las cargas de trabajo y el gasto económico. La colonización y la formación de una película producida por las bacterias (biofilm son considerados factores de riesgo, tanto en las infecciones relacionadas con catéter como en trombosis intraluminal. Para reducir estas complicaciones, utilizábamos como profilaxis un protocolo de sellado en los catéteres con una solución de heparina al 5% más gentamicina. Sin embargo, debido a complicaciones hemorrágicas, infecciosas y a una exposición constante del paciente a antibióticos, se decidió cambiar de protocolo a una solución de citrato trisódico concentrado (46,7% por sus propiedades anticoagulantes y antimicrobianas. Nuestro objetivo es valorar la implantación de un protocolo con citrato trisódico concentrado para el sellado de los catéteres. Los resultados obtenidos en este estudio son: importante descenso en el número de infecciones; menor número de manipulaciones; menor utilización de antibióticos, evitando crear resistencias y sensibilizaciones; dosis dialítica adecuada, disminución del coste económico de las cargas de trabajo y de la morbilidad de los pacientes.Placing a catheter in a central vein as vascular access for haemodialysis is a quick and safe alternative that can be used immediately and lets optimal blood flows be obtained. However, the use of catheters is not free from complications, causing high morbility and increasing the work load and economic cost. The colonization and formation of a film produced by bacteria (biofilm are considered risk factors, both in infections related to the catheter and in intraluminal thrombosis. To reduce these

    Full Text Available Objetivos: El objetivo de este estudio ha sido conocer si el uso crónico de citrato de fentanilo oral puede guardar relación con la aparición de caries y con la pérdida de piezas dentales, y de ser así, si hubiera forma de evitar o minimizar este efecto, a propósito de la aparición de un caso en nuestra unidad. Pacientes y métodos: Se estudió el caso de un varón de 53 años en tratamiento por nuestra Clínica del Dolor, que tomaba citrato de fentanilo oral para el tratamiento de un dolor crónico en el contexto de un síndrome postlaminectomía cervical y lumbar, y en el que aparecieron varias caries y pérdida de piezas dentales. Se revisaron los 77 pacientes a los que en la actualidad, también tratábamos de forma crónica con este fármaco, para estudiar la frecuencia y magnitud de esta posible asociación. Resultados: La higiene dental de los distintos pacientes no varió durante el tratamiento con citrato de fentanilo oral. La existencia de trastornos odontógenos añadidos con posterioridad al inicio del tratamiento, no apareció en ningún otro caso. Este único paciente presentaba un aseo dental defectuoso. Conclusión: El uso crónico de citrato de fentanilo oral es un factor que puede contribuir, aunque de forma infrecuente, a la aparición de caries y pérdida de piezas dentarias. Una adecuada higiene dental podría evitar, o al menos minimizar, la repercusión del uso crónico de citrato de fentanilo oral sobre la salud dentaria.Objectives: The aim of this study was to determine whether the use of oral fentanyl citrate can be related to teeth decay and loss, and if so, whether such effect can be prevented or minimized.

    Full Text Available La Esclerosis Múltiple (EM, es una enfermedad del SNC siendo 2 veces más frecuente su aparición en mujeres, el 70% de ellas en edad fértil. Desde el punto de vista anestésico nos encontramos ante una enfermedad con elevada susceptibilidad neurológica que podría agravarse tanto por la propia cirugía, la técnica anestésica como por la medicación utilizada. Por otra parte se plantea como atender la demanda de analgesia para el trabajo de parto en mujeres con EM, que es el grupo de edad con mayor incidencia de la enfermedad. Presentamos el caso de una mujer de 37 años diagnosticada de esclerosis múltiples 3 años antes, forma recidivante, remitente. La paciente es ingresada en dilatación con 37 semanas de amenorrea, presentando una buena evolución del trabajo de parto y encontrándose el feto en situación longitudinal y presentación cefálica.

La gestante previamente había acudido a consulta de preanestesia donde se le había informado del riesgo beneficio de la técnica y en concreto en su caso, habiendo entendido perfectamente las posibles complicaciones derivadas de la misma y firmado el consentimiento informado. Nosotros hemos preferido utilizar una técnica locoregional, vía epidural considerando también el riesgo potencial de cesárea urgente, para evitar, dado el caso la realización de una técnica intraraquídea o una anestesia general, con las posibilidades de desencadenar un brote que tienen estas técnicas. Además de aportar confort a la paciente durante el trabajo de parto, proporcionar analgesia durante el mismo, disminuye por este motivo el estrés de la gestante pudiendo paralelamente evitar la aparición de un brote.Multiple sclerosis (MS is a disease of the central nervous system (CNS, and twice as prevalent in women, 70% of whom are of fertile age.

    Full Text Available Introducción: la analgesia epidural obstétrica continúa siendo el "gold-standard" para controlar el dolor durante el trabajo de parto, pero en determinadas ocasiones la técnica está contraindicada o la analgesia es incompleta. El remifentanilo es un opioide potente de rápida acción y vida media ultracorta, que se adapta perfectamente a la dinámica del parto. La coordinación entre el comienzo de las contracciones y la administración del fármaco mediante un dispositivo PCA hacen que esta técnica pueda ser considerada de elección para el alivio de dolor durante el parto y no solo como alternativa a la epidural. Objetivo: este estudio pretende valorar la eficacia y seguridad en el parto del remifentanilo administrado por vía intravenosa, así como la satisfacción materna de la analgesia recibida. Materiales y métodos: estudio descriptivo prospectivo basado en el análisis de la recogida de datos realizado por los investigadores durante el parto donde se recoge el dolor durante la dilatación y el expulsivo antes y después de la aplicación de la PCA de remifentanilo, así como las complicaciones y la incidencia de efectos secundarios. Paralelamente se realiza una encuesta de satisfacción materna de la técnica recibida y su vivencia personal. Resultados: se han recogido un total de 32 casos durante el periodo de estudio (6 meses. Todas las pacientes han presentado una reducción de dolor manifestado por una disminución del EVA respecto del dolor basal de 5,9 puntos en los primeros minutos, 4,6 puntos en completa y 3,4 en el expulsivo. No se han registrado complicaciones materno-fetales importantes derivadas de la técnica. La satisfacción materna ha sido alta, volviendo incluso a repetir la técnica en un 90 % de los casos. Conclusiones: la PCA de remifentanilo ha demostrado ser efectiva y segura como analgesia obstétrica. Es por ello que la PCA ha teniendo una amplia aceptación entre matronas, ginecólogos y anestesiólogos en

    INTRODUCCIÓN: el dolor abdominal es un motivo de consulta frecuente. Dado que se presenta como el síntoma principal en diversas enfermedades y que existe la posibilidad de que se generen complicaciones si el diagnóstico no se establece oportunamente, ha habido renuencia a brindar analgesia en forma temprana en estos casos.

    INTRODUCTION: Acute abdominal pain is a very frequent cause of medical consultation. Early analgesia is not usually given to patients that present with it as their chief complaint, because of the many differential diagnoses that must be taken into consideration and also because of fear of the potential complications that may ensue if an early and accurate diagnosis is not made. Nowadays medical practice is evolving and it is pertinent to ask and answer whether it is still adequate to keep the...

    Full Text Available La analgesia multimodal que participa actualmente en todos los protocolos de analgesia postoperatoria también se utiliza por los especialistas en dolor crónico que manejan la combinación de fármacos como una rutina para optimizar la eficacia de la analgesia; la combinación de fármacos es una práctica bien conocida y muy extendida, gracias a su demostrada rentabilidad terapéutica, y habitualmente se utiliza tanto en anestesia como en analgesia. El concepto del balance adecuado entre efectividad y seguridad es primordial, y aunque la calidad del tratamiento aplicado se mide según el alivio conseguido, el confort se evalúa teniendo en cuenta la combinación entre eficacia analgésica y la ausencia o mínima presencia de efectos secundarios, siendo primordial en el tratamiento del paciente con dolor. En este sentido, parece claro que la búsqueda de las dosis mínimas eficaces de cada fármaco es una premisa necesaria para plantear la combinación de dosis idónea. La búsqueda de los fármacos que deben componer una combinación y las dosis a emplear debe ser fruto de la investigación, pero debe ser corroborada por la experiencia clínica, la opinión de los expertos y las evidencias publicadas. En este trabajo, se realiza una extensa revisión de la experiencia clínica existente con la combinación de ibuprofeno con codeína, haciendo un análisis de los antecedentes históricos que llevaron a su uso, los trabajos que permitieron demostrar su sinergia y compatibilidad farmacocinética y los trabajos pioneros de investigación clínica que permitieron concluir que la dosis fija idónea de esta combinación es la mezcla de 400 mg de ibuprofeno con 30 mg de codeína. Es difícil sacar conclusiones acerca de la efectividad analgésica de los diferentes antiinflamatorios no esteroideos, pero no cabe duda que según los datos acumulados hasta la actualidad, el ibuprofeno se sitúa entre los más efectivos y es una buena opción para

    Full Text Available El control del dolor irruptivo (DI en pacientes oncológicos que tienen controlado su dolor basal con altas dosis de opioides se presenta como complejo. No existen referencias en la literatura que orienten sobre el fármaco, dosis y vía de administración adecuada para su tratamiento, por lo que este se fundamenta en conductas no estandarizadas, basadas en la práctica clínica. Con el presente estudio queremos dar a conocer nuestra experiencia en el tratamiento de este tipo de dolor en este tipo de pacientes. Objetivos: Evaluar la efectividad y seguridad de CFOT en el tratamiento de las crisis de DI en pacientes oncológicos que tienen controlado su dolor de base con dosis elevadas, comparándolo con los tratamientos que recibían previamente. Se evaluó, así mismo, el grado de satisfacción del paciente respecto a la medicación evaluada. Material y métodos: Sobre un total de 280 pacientes oncológicos visitados en nuestro servicio durante el año 2003, 25 reunían los criterios requeridos. A todos ellos se les instó a tratar sus crisis de DI con CFOT, con dosis iniciales de 400 mcg, que podían incrementar, en función de respuesta y efectos adversos. Para ello, se evaluó respuesta clínica según valoración Escala Analógica Visual, y se recogieron todos los efectos adversos relacionados con la medicación y reportados por los pacientes. Por último, se valoró el grado de satisfacción del paciente mediante el cuestionario propuesto por Kornick. Resultados: Las dosis media efectiva con la que se controlaba las crisis de DI fue de 600 mcg, la titulación se consiguió en la mayoría de los casos a los 2 días, los efectos adversos fueron los típicamente observados con el tratamiento opioide. La mayoría de pacientes prefirieron CFOT a sus tratamientos previos. Los pacientes consideraron las pautas de tratamiento como sencillas de cumplir. Conclusiones: CFOT puede considerarse como una opción segura y efectiva en el tratamiento de las

    Full Text Available Introducción: la literatura científica indica que dos de cada tres pacientes con dolor crónico sufren con cierta frecuencia exacerbaciones puntuales del mismo debido a diferentes causas, en ocasiones previsibles, y en otras inesperadas. Además del sufrimiento que conllevan, estos episodios constituyen un problema importante para el paciente pues generan ansiedad y añaden incapacidad funcional, lo cual se traduce en una mayor dificultad para controlar el dolor basal y una menor calidad de vida. En 1990 se acuñó en Estados Unidos el término "break-through pain", para definir a las exacerbaciones transitorias de un dolor oncológico, que está bien controlado con la utilización de opioides mayores. En el año 2002, la Sociedad Española de Oncología Médica (SEOM, la Sociedad Española de Cuidados Paliativos (SECPAL y la Sociedad Española del Dolor (SED, establecieron un documento de consenso en el que asumieron el término "dolor irruptivo", para definir una exacerbación del dolor de forma súbita y transitoria, de gran intensidad (EVA > 7 y de corta duración (usualmente inferior a 20-30 minutos, que aparece sobre la base de un dolor persistente estable, cuando este se encuentra reducido a un nivel tolerable (EVA 5 en las últimas 12-24 horas y/o efectos secundarios indeseables originados por el tratamiento actual del dolor irruptivo.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: Embora a tetralogia de Fallot seja a mais comum das cardiopatias congênitas cianóticas, as publicações nacionais, relacionando essa doença com a prática anestésica são escassas. O objetivo deste relato é apresentar um caso de analgesia de parto em paciente portadora de tetralogia de Fallot não corrigida e diagnosticada durante a gestação. RELATO DO CASO: Paciente com 26 anos, 56 kg, 1,56 m, idade gestacional 32 semanas e 5 dias, com diagnóstico de tetralogia de Fallot realizado durante a gestação. Internou em trabalho de parto. A conduta obstétrica foi a de parto via baixa, sendo realizada analgesia através de bloqueio peridural com bupivacaína a 0,125% e fentanil (100 µg e colocação de cateter peridural. Após 1h30 minutos do início da analgesia, ocorreu o nascimento. O peso do recém-nascido foi 1485 g e o índice de Apgar 6 e 8 no primeiro e no quinto minutos, respectivamente. A paciente permaneceu estável e sem alterações hemodinâmicas e/ou eletrocardiográficas. CONCLUSÕES: A escolha da técnica anestésica é de fundamental importância no manuseio das pacientes com tetralogia de Fallot não corrigidas. Condições favoráveis do colo e boa dinâmica uterina, particularmente naquelas pacientes sem história de síncope, tornam-se imprescindíveis para uma boa indicação da analgesia de parto.JUSTIFICATIVA Y OBJETIVOS: Aunque la tetralogía de Fallot sea la más común de las cardiopatías congénitas cianóticas, las publicaciones nacionales, relacionando esa enfermedad con la práctica anestésica son escasas.

El citrato de fentanilo oral transmucosa (CFOT es un fármaco recientemente introducido en nuestro país, que ha sido específicamente desarrollado para el tratamiento de este tipo de dolor. Tras su comercialización en el año 2001, se planteó la realización de un estudio observacional post-autorización con el objetivo de evaluar la seguridad y tolerabilidad del mismo. Adicionalmente se planteó la obtención de datos de efectividad del CFOT y la comparación de los mismos con los obtenidos hasta la visita basal para otros tratamientos administrados, distintos a CFOT. Métodos: Para el estudio se reclutaron 312 pacientes oncológicos, con dolor de base controlado con opioides, que presentaban crisis de dolor irruptivo y fueron seguidos durante un mes, realizándose visitas de control semanales. Doscientos noventa y cinco pacientes fueron válidos para el estudio de la seguridad y tolerabilidad de CFOT (población de seguridad. Por otra parte, 138 pacientes fueron evaluados para efectividad, ya que cumplían los criterios de inclusión y exclusión del estudio y les habían sido administrados tratamientos distintos a CFOT antes de la visita basal.

    Full Text Available JUSTIFICATIVA E OBJETIVO: Cirurgias artroscópicas do ombro cursam com intensa dor pós-operatória. Diversas técnicas analgésicas têm sido preconizadas. O objetivo deste estudo foi comparar o bloqueio dos nervos supraescapular e axilar nas cirurgias artroscópicas de ombro com a abordagem interescalênica do plexo braquial. MÉTODO: Sessenta e oito pacientes foram alocados em dois grupos de 34, de acordo com a técnica utilizada: grupo interescalênico (GI e grupo seletivo (GS, sendo ambas as abordagens realizadas com neuroestimulador. No GI, após resposta motora adequada foram injetados 30 mL de levopubivacaína em excesso enantiomérico de 50% a 0,33% com adrenalina 1:200.000. No GS, após resposta motora do nervo supraescapular e axilar, foram injetados 15 mL da mesma substância em cada nervo. Em seguida, realizada anestesia geral. Variáveis avaliadas: tempo para realização dos bloqueios, analgesia, consumo de opioide, bloqueio motor, estabilidade cardiocirculatória, satisfação e aceitabilidade pelo paciente. RESULTADOS: Tempo para execução do bloqueio interescalênico foi significativamente menor que para realização do bloqueio seletivo. Analgesia foi significativamente maior no pós-operatório imediato no GI e no pós-operatório tardio no GS. Consumo de morfina foi significativamente maior na primeira hora no GS. Bloqueio motor foi significativamente menor no GS. Estabilidade cardiocirculatória, satisfação e aceitabilidade da técnica pelo paciente não diferiram entre os grupos. Ocorreu uma falha no GI e duas no GS. CONCLUSÕES: Ambas as técnicas são seguras, eficazes com mesmo grau de satisfação e aceitabilidade. O bloqueio seletivo de ambos os nervos apresentou analgesia satisfatória, com a vantagem de proporcionar bloqueio motor restrito ao ombro.JUSTIFICATIVA Y OBJETIVOS: Las cirugías artroscópicas del hombro cursan con un intenso dolor postoperatorio.

Concretamente, en los pacientes oncológicos se puede presentar un dolor rectal irruptivo defecatorio debido al tumor, los efectos secundarios de los tratamientos administrados (cirugía, radioterapia y/o quimioterapia o ambos. Recientemente, ha aparecido un sistema de administración transmucosa oral, citrato de fentanilo oral transmucosa (CFOT (Actiq® como método de alta eficacia para un inicio rápido de la analgesia. El objetivo de este trabajo es valorar la eficacia de CFOT como analgésico en este subgrupo tan específico de pacientes oncológicos. Pacientes y métodos: Entre enero de 2006 y julio de 2009 hemos revisado retrospectivamente un total de 10 pacientes tratados en nuestro servicio con CFOT por dolor rectal irruptivo defecatorio no premedicados con opiáceos. Cuando los pacientes referían en consulta dolor rectal se les valoraba con una escala visual analógica (EVA (0-10. Resultados: La puntuación media premedicación con CFOT de dolor irruptivo defecatorio con la EVA fue de 7 (rango: 5-9. La puntuación media tras el tratamiento pasó a ser 1,9 (rango: 1-3. Todos refirieron controlar el dolor con dosis de 200 µg de CFOT, salvo 2 pacientes que precisaron dosis progresivas de 400 y 600 µg, respectivamente. El grado de satisfacción de los pacientes fue excelente-bueno en el 90% de los casos. Ningún paciente refirió efectos indeseables relacionados con el uso de CFOT. Conclusiones: Aunque nuestra serie es corta y, por lo tanto, sus resultados son muy preliminares, podemos recomendar el CFOT como analgésico ideal por su rapidez y seguridad para el tratamiento del dolor rectal irruptivo defecatorio. Es de fácil y cómoda administración, y de corta duración. Ofrece al paciente independencia al poderlo tomar, aunque se encuentre fuera de su domicilio. CFOT se puede

  12. Ethanol-induced analgesia

    1987-09-07

    The effect of ethanol (ET) on nociceptive sensitivity was evaluated using a new tail deflection response (TDR) method. The IP injection of ET (0.5 - 1.5 g/kg) produced raid dose-dependent analgesia. Near maximal effect (97% decrease in TDR) was produced with the 1.5 g/kg dose of ET ten minutes after injection. At ninety minutes post-injection there was still significant analgesia. Depression of ET-induced nociceptive sensitivity was partially reversed by a 1 mg/kg dose of naloxone. On the other hand, morphine (0.5 or 5.0 mg/kg IP) did not modify ET-induced analgesia, while 3.0 minutes of cold water swim (known to produce non-opioid mediated analgesia) potentiated ET-induced analgesic effect. The 0.5 g/kg dose of ET by itself did not depress motor activity in an open field test, but prevented partially the depression in motor activity produced by cold water swim (CWS). Thus, the potentiation by ET of the depression of the TDR produced by CWS cannot be ascribed to the depressant effects of ET on motor activity. 21 references, 4 figures, 1 table.

    diferentes bloqueos de nervios periféricos. El objetivo de este estudio, fue comparar la eficacia de la analgesia postoperatoria, resultante de la administración en dosis única de la bupivacaína a 0,5% o de la ropivacaína a 0,5% en el bloqueo del plexo lumbar por la vía posterior en la artroplastia total de la cadera. MÉTODO: Treinta y siete pacientes fueron ubicados aleatoriamente en dos grupos según el anestésico local utilizado en el bloqueo: Grupo B - bupivacaína a 0,5% con epinefrina 1:200.000 o Grupo R - ropivacaína a 0,5%. Durante el período postoperatorio, los puntajes de dolor y el consumo de morfina en la analgesia controlada por el paciente, fueron comparados entre los grupos. El sangramiento durante la operación y la incidencia de efectos adversos y de complicaciones también fueron comparados. RESULTADOS: Pese a que los puntajes de dolor hayan sido menores en el Grupo R 8 horas, 12 horas y 24 horas después del bloqueo, esas diferencias no fueron clínicamente significativas. La regresión lineal múltiple no identificó el anestésico local como una variable independiente. No hubo diferencia en el consumo de morfina, en el sangramiento intraoperatorio y en la incidencia de complicaciones y efectos adversos entre los dos grupos. CONCLUSIONES: La bupivacaína a 0,5% y la ropivacaína a 0,5%, ofrecieron un alivio eficaz y prolongado del dolor postoperatorio después de la artroplastia total de la cadera, sin diferencia clínica, cuando dosis equivalentes fueron administradas en el bloqueo del plexo lumbar por la vía posteriorBACKGROUND AND OBJECTIVES: Posterior lumbar plexus block promotes effective postoperative analgesia in total knee arthroplasty.

    Full Text Available Background: Epidural analgesia is claimed to result in prolonged labor. Previous studies have assessed epidural analgesia vs systemic opioids rather than to parturients receiving no analgesia. This study aimed to evaluate the effect of epidural analgesia on labor duration compared with parturients devoid of analgesia. Methods: One hundred sixty nulliparous women in spontaneous labor at full term with a singleton vertex presentation were assigned to the study. Parturients who request epidural analgesia were allocated in the epidural group, whereas those not enthusiastic to labor analgesia were allocated in the control group. Epidural analgesia was provided with 20 mL bolus 0.5% epidural lidocaine plus fentanyl and maintained at 10 mL for 1 h. Duration of the first and second stages of labor, number of parturients receiving oxytocin, maximal oxytocin dose required for each parturient, numbers of instrumental vaginal, vacuum-assisted, and cesarean deliveries and neonatal Apgar score were recorded. Results: There was no statistical difference in the duration of the active-first and the second stages of labor, instrumental delivery, vacuum-assisted or cesarean delivery rates, the number of newborns with 1-min and 5-min Apgar scores less than 7 between both groups and number of parturients receiving oxytocin, however, the maximal oxytocin dose was significantly higher in the epidural group. Conclusion: Epidural analgesia by lidocaine (0.5% and fentanyl does not prolong labor compared with parturients without analgesia; however, significant oxytocin augmentation is required during the epidural analgesia to keep up the aforementioned average labor duration.

    Full Text Available La adrenalina ha sido ampliamente utilizada junto con anestésicos locales, tanto a nivel periférico como central, desde que Heinrich Braun fuera el pionero en experimentar con ella al inicio de 1900. Un siglo de uso atestigua su seguridad general como coadyuvante, a pesar de que todavía poseemos un conocimiento parcial de su modo de actuar, consiguiendo una prolongación del bloqueo nervioso, una reducción de las concentraciones plasmáticas de los anestésicos locales, una reducción del sangrado quirúrgico y una potenciación del efecto analgésico. El convencimiento durante largo tiempo de que la adrenalina muestra todos estos efectos beneficiosos, así como los negativos, únicamente por vasoconstricción, es demasiado simplista y actualmente insuficiente. El objetivo principal de esta revisión se centrará en demostrar como la adrenalina epidural es capaz de mejorar la analgesia postoperatoria cuando forma parte de una mezcla junto a bupivacaína o ropivacaína y fentanilo.Epinephrine has been combined with neuraxial and peripheral local anesthetics since Heinrich Braun first experimented with its use in the early 1900s. A century of use attests to the general safety of adjuvant epinephrine, yet we have only modest understanding of its intended effects, which include prolonging block duration, reducing plasma concentrations of local anesthetics, reducing surgical bleeding and intensifying anesthesia and analgesia. The long-held belief that epinephrine exerts most of these effects, including any associated complications, by causing vasoconstriction is doubtlessly too simplistic and has been recently challenged. The main part of this chapter will therefore focus on the advantages and disadvantages of epinephrine in epidural analgesia and on optimizing postoperative analgesia by adding epinephrine and/or fentanyl to an epidural mixture with dilute bupivacaine or ropivacaine.

    Labor pain is one of the most severe pains. Labor is a complex and individual process with varying maternal requesting analgesia. Labor analgesia must be safe and accompanied by minimal amount of unwanted consequences for both the mother and the child, as well as for the delivery procedure. Epidural analgesia is the treatment that best meets these demands. According to the American Congress of Obstetrics and Gynecology and American Society of Anesthesiologists, mother's demand is a reason enough for the introduction of epidural analgesia in labor, providing that no contraindications exist. The application of analgesics should not cease at the end of the second stage of labor, but it is recommended that lower concentration analgesics be then applied. Based on the latest studies, it can be claimed that epidural analgesia can be applied during the major part of the first and second stage of labor. According to previous investigations, there is no definitive conclusion about the incidence of instrumental delivery, duration of second stage of labor, time of epidural analgesia initiation, and long term outcomes for the newborn. Cooperation of obstetric and anesthesiology personnel, as well as appropriate technical equipment significantly decrease the need of instrumental completion of a delivery, as well as other complications encountered in the application of epidural analgesia. Our hospital offers 24/7 epidural analgesia service. The majority of pregnant women in our hospital were aware of the advantages of epidural analgesia for labor, however, only a small proportion of them used it, mainly because of inadequate level of information.

    Full Text Available El objetivo de esta revisión es una puesta al día en la etiología, diagnóstico, profilaxis y tratamiento de la meningitis tras anestesia y analgesia espinales. Aunque es una complicación mayor de esta técnica y su incidencia es baja, cada vez son más frecuentes los casos publicados en la literatura médica. Según su etiología se les clasifica en meningitis sépticas, víricas y asépticas. Las meningitis sépticas son las más frecuentes, y en su etiología cada vez juega un papel más destacado como agente implicado el estreptococo salivarius. Como meningitis asépticas se clasifican aquellas en las que el cultivo de líquido cefalorraquídeo es negativo, con un periodo de latencia de síntomas inferior a seis horas, que pueden cursar con eosinofilia en el líquido cefalorraquídeo y unos niveles cercanos a la normalidad en la glucorraquia. Suelen tener buena respuesta y evolución con tratamiento antibiótico con vancomicina y cefalosporinas de tercera generación. Como profilaxis incidir en las medidas de asepsia, sobre todo en el uso de mascarilla facial para realizar la técnica, como práctica para disminuir la incidencia de gérmenes cuyo origen está en la cavidad oral y orofaringe. Asimismo podrían reducir la incidencia de meningitis las medidas de asepsia tales como el lavado de manos, uso de guantes y asepsia de la piel. La diferenciación entre meningitis séptica y aséptica se hará con mayor seguridad cuando se estandaricen las técnicas para detectar genoma bacteriano en el líquido cefalorraquídeo; actualmente se etiquetan como meningitis asépticas aquellas en las que el cultivo de líquido cefalorraquídeo es negativo y cuya tinción de Gram es negativa. Pese a que el pronóstico y evolución en rasgos generales de las meningitis tras anestesia y analgesia espinal es bueno, en comparación con las meningitis adquiridas en la comunidad, por la escasa virulencia de las bacterias implicadas (Estreptococo salivarius

A prospective and consecutive series of 1,316 patients undergoing surgery from September 1999 to April 2003 and using opioids post surgery were studied. From the 1,136 patients, 594 did not use urinary catheters pre-surgery. From these 594 patients, 128 (22% suffered post operative urinary retention. Urinary retention was significantly related to the use of continuous epidural analgesia (p=0.009. About 69% of patients experiencing urinary retention post surgery returned to spontaneous micturition following a single catheterization. The incidence found of urinary retention was similar to the literature, more frequent in men who received continuous epidural analgesia.

    The correct treatment of postoperative pain, in the early period immediately following surgery, is founded on the following four principles: 1-correct diagnosis of the source and magnitude of nociception; 2-understanding of the relationship of ongoing nociception and other components of pain including anxiety, ethnocultural components, meaning, prior experience; 3-treatment by establishment and maintenance of drug level at active sites to achieve and maintain analgesia and anxiolysis as appropriate; 4-continued re-evaluation of the therapy and refinement of the approach. The PACU standard of cure requires a strict accordance between intra and postoperative analgesia. It requires "proactive preoperative plan" that includes: preoperative patient evaluation; discussion with a single patient on different treatment options; patient and family education; pre-emptive measures as indicated; intra-operative multimodal analgesia; a correct triage of analgesia, just after initial evaluation of vital parameters in PACU; re-evaluation of analgesia plan, if analgesia is inadequate; a new titration, intravenous or epidural way, in order to achieve a stable VAS < 3; plan a new analgesia scheme or confirm a preoperative plan; control of adverse events, related to analgesia plan (gastric bleeding and/or bleeding of the surgical wound site, NSAIDs-induced renal damage, respiratory depression, delayed canalisation, nausea, vomiting, excessive sedation, difficulty in bladder emptying, itchiness); a transmission of analgesia plan to ward nurses; a control quality for verify at prefixed times patients satisfaction level, analgesia performed, adverse effects percent, analgesia related, plan variations percent.

    Full Text Available Polímeros sintéticos biorreabsorvíveis podem ser utilizados sob a forma de membranas para sustentar e guiar o crescimento celular, através do processo de reparação tecidual. Este trabalho avaliou membranas de poli(ácido lático, PLLA, com adição de 10% de trietil-citrato usadas como curativos de feridas cutâneas agudas em ratos Wistar. Inicialmente uma ferida de 2cm² foi provocada na região dorsal de 24 animais. Estes foram divididos em 2 grupos: tratamento, nos quais as feridas foram recobertas pela membrana polimérica e controle, com feridas permanecendo cruentas. Os resultados obtidos em 1, 3, 7 e 15 dias mostraram uma resposta inflamatória mais satisfatória nas feridas protegidas pelas membranas, com reparação precoce e colágeno mais organizado quando comparadas com as áreas incialmente mantidas sem proteção. Além do que, as áreas protegidas pelas membranas não mostraram alterações inflamatórias irritativas que pudessem ser imputadas ao uso da membrana polimérica. Diante disso, conclui-se que a membrana de PLLA/Trietil-citrato protegeu efetivamente as feridas, permitindo o processo de reparação e mostrando-se promissora como curativo cutâneo.

    Full Text Available The intake of saccharin solutions for relatively long periods of time causes analgesia in rats, as measured in the hot-plate test, an experimental procedure involving supraspinal components. In order to investigate the effects of sweet substance intake on pain modulation using a different model, male albino Wistar rats weighing 180-200 g received either tap water or sucrose solutions (250 g/l for 1 day or 14 days as their only source of liquid. Each rat consumed an average of 15.6 g sucrose/day. Their tail withdrawal latencies in the tail-flick test (probably a spinal reflex were measured immediately before and after this treatment. An analgesia index was calculated from the withdrawal latencies before and after treatment. The indexes (mean ± SEM, N = 12 for the groups receiving tap water for 1 day or 14 days, and sucrose solution for 1 day or 14 days were 0.09 ± 0.04, 0.10 ± 0.05, 0.15 ± 0.08 and 0.49 ± 0.07, respectively. One-way ANOVA indicated a significant difference (F(3,47 = 9.521, P<0.001 and the Tukey multiple comparison test (P<0.05 showed that the analgesia index of the 14-day sucrose-treated animals differed from all other groups. Naloxone-treated rats (N = 7 receiving sucrose exhibited an analgesia index of 0.20 ± 0.10 while rats receiving only sucrose (N = 7 had an index of 0.68 ± 0.11 (t = 0.254, 10 degrees of freedom, P<0.03. This result indicates that the analgesic effect of sucrose depends on the time during which the solution is consumed and extends the analgesic effects of sweet substance intake, such as saccharin, to a model other than the hot-plate test, with similar results. Endogenous opioids may be involved in the central regulation of the sweet substance-produced analgesia.

    Relief of pain and safety of mother and child are fundamentals in obstetrical analgesia. Elimination of those drugs which are ineffective or dangerous is the best guide to proper medication. Morphine, codeine, or similar opium derivatives should be avoided as they depress fetal respiration. Barbiturates have the same fault, despite their popularity. Demerol in small dosage is safe and effective. Scopolamine yields excellent results with safety. Magnesium sulfate potentiates and reinforces the action of scopolamine and involves no danger. This combination of drugs may be used by any competent general practitioner in the home or hospital. PMID:13126811

    Elderly people represent the fastest-growing segment of our society and undergo surgery more frequently than other age groups. Effective postoperative analgesia is essential in these patients because inadequate pain control after surgery is associated with adverse outcomes in elderly patients. However, management of postoperative pain in older patients may be complicated by a number of factors, including a higher risk of age- and disease-related changes in physiology and disease-drug and drug-drug interactions. Physiological changes related to aging need to be carefully considered because aging is individualized and progressive. Assessment of pain management needs to include chronological age, biological age with regard to renal, liver and cardiac functions, and the individual profile of pathology and prescribed medications. In addition, ways in which pain should be assessed, particularly in patients with cognitive impairment, must be considered. Cognitively intact older patients can use most commonly used unidimensional pain scales such as the visual analogue scale (VAS), verbal rating scale (VRS), numeric rating scale (NRS) and facial pain scale (FPS). VRS and NRS are the most appropriate pain scales for the elderly. In older patients with mild to moderate cognitive impairment, the VRS is a better tool. For severe cognitively impaired older patients, behavioural scales validated in the postoperative context, such as Doloplus-2 or Algoplus, are appropriate. For postoperative pain treatment, most drugs (e.g. paracetamol, nonsteroidal anti-inflammatory drugs, nefopam, tramadol, codeine, morphine, local anaesthetics), techniques (e.g. intravenous morphine titration, subcutaneous morphine, intravenous or epidural patient-controlled analgesia, intrathecal morphine, peripheral nerve block) and strategies (e.g. anticipated intraoperative analgesia or multimodal analgesia) used for acute pain management can be used in older patients. However, in view of pharmacokinetic

    Timely management of pain in paediatric patients in the Emergency Department (ED) is a well-accepted performance indicator. We describe an audit of the provision of analgesia for children in an Irish ED and the introduction of a nurse-initiated analgesia protocol in an effort to improve performance. 95 children aged 1-16 presenting consecutively to the ED were included and time from triage to analgesia, and the rate of analgesia provision, were recorded. The results were circulated and a nurse initiated analgesia protocol was introduced. An audit including 145 patients followed this. 55.6% of patients with major fractures received analgesia after a median time of 54 minutes, which improved to 61.1% (p = 0.735) after 7 minutes (p = 0.004). Pain score documentation was very poor throughout, improving only slightly from 0% to 19.3%. No child had a documented pain score, which slightly improved to 19.3%. We recommend other Irish EDs to audit their provision of analgesia for children.

  14. Remifentanil patient controlled analgesia versus epidural analgesia in labour. A multicentre randomized controlled trial

    Directory of Open Access Journals (Sweden)

    Freeman Liv M

    2012-07-01

    Full Text Available Abstract Background Pain relief during labour is a topic of major interest in the Netherlands. Epidural analgesia is considered to be the most effective method of pain relief and recommended as first choice. However its uptake by pregnant women is limited compared to other western countries, partly as a result of non-availability due to logistic problems. Remifentanil, a synthetic opioid, is very suitable for patient controlled analgesia. Recent studies show that epidural analgesia is superior to remifentanil patient controlled analgesia in terms of pain intensity score; however there was no difference in satisfaction with pain relief between both treatments. Methods/design The proposed study is a multicentre randomized controlled study that assesses the cost-effectiveness of remifentanil patient controlled analgesia compared to epidural analgesia. We hypothesize that remifentanil patient controlled analgesia is as effective in improving pain appreciation scores as epidural analgesia, with lower costs and easier achievement of 24 hours availability of pain relief for women in labour and efficient pain relief for those with a contraindication for epidural analgesia. Eligible women will be informed about the study and randomized before active labour has started. Women will be randomly allocated to a strategy based on epidural analgesia or on remifentanil patient controlled analgesia when they request pain relief during labour. Primary outcome is the pain appreciation score, i.e. satisfaction with pain relief. Secondary outcome parameters are costs, patient satisfaction, pain scores (pain-intensity, mode of delivery and maternal and neonatal side effects. The economic analysis will be performed from a short-term healthcare perspective. For both strategies the cost of perinatal care for mother and child, starting at the onset of labour and ending ten days after delivery, will be registered and compared. Discussion This study, considering cost

    2014-12-30

    Although non-suicidal self-injury (NSSI) involves self-inflicted physical harm, many self-injurers report feeling little or no pain during the act. Here we test: (1) whether the pain analgesia effects observed among adult self-injurers are also present among adolescents, and (2) three potential explanatory models proposing that habituation, dissociation, and/or self-criticism help explain the association between NSSI and pain analgesia among adolescents. Participants were 79 adolescents (12-19 years) recruited from the community who took part in a laboratory-based pain study. Results revealed that adolescent self-injurers have a higher pain threshold and greater pain endurance than non-injurers. Statistical mediation models revealed that the habituation and dissociation models were not supported; however, a self-critical style does mediate the association between NSSI and pain analgesia. The present findings extend earlier work by highlighting that a self-critical style may help to explain why self-injurers exhibit pain analgesia. Specifically, the tendency to experience self-critical thoughts in response to stressful events may represent a third variable that increases the likelihood of both NSSI and pain analgesia. Prospective experimental studies are needed to replicate and tease apart the direction of these associations, and may provide valuable leads in the development of effective treatments for this dangerous behavior problem.

Analgesia duration and patients’ complaints were evaluated. RESULTS: Analgesia was considered satisfactory for both groups. Mean analgesia duration was 505 minutes for Group IP and 620 minutes for Group IC, with no statistical significant difference. Nausea, vomiting and mild abdominal pain were the most frequent postoperative complaints. There was no postoperative complication related to blockade and no pneumothorax was detected

    2016-01-01

    Nefopam is a non-opioid, non-steroidal, centrally acting analgesic drug used to prevent postoperative pain, primarily in the context of multimodal analgesia. This paper reviews preclinical and clinical studies in which nefopam has been combined with opioids, non-steroidal anti-inflammatory compounds, and paracetamol. This report focuses on the literature during the last decade and discusses the translational efforts between animal and clinical studies in the context of multimodal or balanced analgesia. In preclinical rodent models of acute and inflammatory pain, nefopam combinations including opioids revealed a synergistic interaction or enhanced morphine analgesia in six out of seven studies. Nefopam combinations including non-steroidal anti-inflammatory drugs (NSAIDs) (aspirin, ketoprofen or nimesulide) or paracetamol likewise showed enhanced analgesic effects for the associated compound in all instances. Clinical studies have been performed in various types of surgeries involving different pain intensities. Nefopam combinations including opioids resulted in a reduction in morphine consumption in 8 out of 10 studies of severe or moderate pain. Nefopam combinations including NSAIDs (ketoprofen or tenoxicam) or paracetamol also demonstrated a synergic interaction or an enhancement of the analgesic effect of the associated compound. In conclusion, this review of nefopam combinations including various analgesic drugs (opioids, NSAIDs and paracetamol) reveals that enhanced analgesia was demonstrated in most preclinical and clinical studies, suggesting a role for nefopam in multimodal analgesia based on its distinct characteristics as an analgesic. Further clinical studies are needed to evaluate the analgesic effects of nefopam combinations including NSAIDs or paracetamol. PMID:26475417

    We consider that the present state of postoperative analgesia is unsatisfactory because drugs are given intermittently and usually only at the patients' request and with nurses' acquiescence. A procedure for routine continuous pethidine infusion, suitable for administration and control by the nursing staff is described. The results of a trial on patients after major surgery are summarised. We believe the procedure to be more efficient and effective than those presently in use.

    Obstetric anesthesia has made significant progress over the last 50 years. It is one of the major subspecialties in anesthesia in US. Society for Obstetric Anesthesia and Perinatology (SOAP) was founded in 1968. According to its SCORE project on the practice of obstetric anesthesia, 82.4% of all parturients received some form of anesthesia for cesarean section or labor analgesia. Epidural analgesia was the most common form of labor analgesia (65%), followed by CSEA. This high percentage of anesthesia care for parturients mandates the presence of obstetric anesthesiologists at labor and delivery suites in major hospitals in US. The Japanese Society of Obstetrics and Anesthesia, formerly "Mutsu-bunben Kenkyukai", now called "Bunben to Masui Kenkyukai", was founded in Japan at about the same time as SOAP. Despite its long history, obstetric anesthesia is yet to be a major subspecialty in Japan. It is encouraging, however, that the number of attendants in obstetric anesthesia sessions in JSA seems increasing. SOAP has played an important role in the education and progress of obstetric anesthesia in US. I hope that the joint symposium of SOAP, Bunben to Masui Kenkyukai, and JSA at 39th SOAP annual meeting will facilitate the progress of obstetric anesthesia in Japan. PMID:17877044

    Full Text Available Intrathecal analgesia is an interventional form of pain relief with definite advantages and multiple complications. Administration of intrathecal analgesia needs a good resource setting and expertise. Early complications of intrathecal analgesia can be very distressing and managing these complications will need a high degree of knowledge, technical expertise and level of experience. Pain control alone cannot be the marker of quality in palliative care. A holistic approach may need to be employed that is more person and family oriented.

Por otro lado, con el envejecimiento de la población, el período de recuperación pós-operatoria pasó a ser motivo de mayor preocupación y consecuente preocupación del equipo de salud. Para tanto, nuevas técnicas de analgesia fueron creadas y desarrolladas y, entre ellas, se destaca la Analgesia Controlada por el Paciente (ACP. En nuestro país, el Servicio de Dolor Agudo (SEDA de la Disciplina de Terapia Antálgica y Cuidados Paliativos, del Departamento de Anestesiología de la Facultad de Medicina de Botucatu - UNESP, utiliza hace muchos años esta técnica de analgesia. Con la finalidad de atestar la calidad del servicio prestado, la pesquisa objetiva verificar la eficacia y seguridad del método, así como identificar y caracterizar la población atendida. MÉTODO: De modo retrospectivo, fueron evaluados 679 pacientes tratados por el SEDA, exclusivamente con el método de ACP, durante tres años. Los pacientes fueron incluidos en el análisis aleatoriamente, sin restricciones cuanto a la edad, al sexo, al tipo de cirugía y considerando únicamente la posibilidad de indicación de la ACP. Fueron estudiados los siguientes atributos: sexo, edad, tipo de cirugía, intensidad del dolor, días de acompañamiento, analgésicos utilizados, vías de administración, ocurrencia de efectos colaterales y complicaciones de la técnica.

  10. Selective REM Sleep Deprivation Improves Expectation-Related Placebo Analgesia.

    Florian Chouchou

    Full Text Available The placebo effect is a neurobiological and psychophysiological process known to influence perceived pain relief. Optimization of placebo analgesia may contribute to the clinical efficacy and effectiveness of medication for acute and chronic pain management. We know that the placebo effect operates through two main mechanisms, expectations and learning, which is also influenced by sleep. Moreover, a recent study suggested that rapid eye movement (REM sleep is associated with modulation of expectation-mediated placebo analgesia. We examined placebo analgesia following pharmacological REM sleep deprivation and we tested the hypothesis that relief expectations and placebo analgesia would be improved by experimental REM sleep deprivation in healthy volunteers. Following an adaptive night in a sleep laboratory, 26 healthy volunteers underwent classical experimental placebo analgesic conditioning in the evening combined with pharmacological REM sleep deprivation (clonidine: 13 volunteers or inert control pill: 13 volunteers. Medication was administered in a double-blind manner at bedtime, and placebo analgesia was tested in the morning. Results revealed that 1 placebo analgesia improved with REM sleep deprivation; 2 pain relief expectations did not differ between REM sleep deprivation and control groups; and 3 REM sleep moderated the relationship between pain relief expectations and placebo analgesia. These results support the putative role of REM sleep in modulating placebo analgesia. The mechanisms involved in these improvements in placebo analgesia and pain relief following selective REM sleep deprivation should be further investigated.

    We assessed the effectiveness of early patient-controlled oral analgesia compared with parenteral analgesia in a randomised controlled non-inferiority trial of women undergoing elective caesarean section under regional anaesthesia. Seventy-seven women received multimodal paracetamol, ketoprofen and morphine analgesia. The woman having patient-controlled oral analgesia were administered four pillboxes on the postnatal ward containing tablets and instructions for self-medication, the first at 7 h after the spinal injection and then three more at 12-hourly intervals. Pain at rest and on movement was evaluated using an 11-point verbal rating scale at 2 h and then at 6-hourly intervals for 48 h. The pre-defined non-inferiority limit for the difference in mean pain scores (patient-controlled oral analgesia minus parenteral) was one. The one-sided 95% CI of the difference in mean pain scores was significantly lower than one at all time-points at rest and on movement, demonstrating non-inferiority of patient-controlled oral analgesia. More women used morphine in the patient-controlled oral analgesia group (22 (58%)) than in the parenteral group (9 (23%); p = 0.002). The median (IQR [range]) number of morphine doses in the patient-controlled oral analgesia group was 2 (1-3 [1-7]) compared with 1 (1-1 [1-2]); p = 0.006) in the parenteral group. Minor drug errors or omissions were identified in five (13%) women receiving patient-controlled oral analgesia. Pruritus was more frequent in the patient-controlled oral analgesia group (14 (37%) vs 6 (15%) respectively; p = 0.03), but no differences were noted for other adverse events and maternal satisfaction. After elective caesarean section, early patient-controlled oral analgesia is non-inferior to standard parenteral analgesia for pain management, and can be one of the steps of an enhanced recovery process.

    2012-01-01

    Full Text Available Introduction. Epidural analgesia has become the most popular method for labor pain relief. Analgesia in Labor: Yes or No? Labor pain is a complex phenomenon with sensory, cognitive, motivational, emotional, social, and cultural variables. Pain and anxiety lead to adrenergic hyperactivity, hyperventilation, hypocapnia with reduced uteroplacental blood flow and uncoordinated uterine activity, so pain relief is recommended and even indicated in cases of maternal comorbidity. Analgesia in Labor: Method of Choice. The quality of epidural analgesia is better than the one achieved by parenteral or inhalation agents, with increased uteroplacental blood flow and improved fetal-maternal oxygenation. Epidural Analgesia in Labor: What is Specific? The increased weight, lumbar lordosis, soft tissue edema and engorgement of epidural veins make it more difficult to perform epidural block in pregnancy. Epidural puncture should be performed by medial approach, at L2 - 3 or L3 - 4 level by loss of resistance technique between contractions. Epidural Analgesia in Labor: What With? Local anesthetics, bupivacaine, levobupivacaine, ropivacaine, are used and they can be combined with small doses of opioids (fentanyl or sufentanyl. Epidural Analgesia in Labor: How? Available techniques are epidural, spinal and combined spinal - epidural analgesia. Epidural Analgesia in Labor: Controversies. The most important controversy is the influence of epidural analgesia on operative or instrumental delivery rate. Low concentrations of local anesthetic in combination with small doses of opioids, together with active management of labor by an obstetrician, would lead to increased spontaneous delivery rate. Conclusion. Although there still are some difficulties, complications and controversies, epidural analgesia provides safe and effective labor pain control.

    Full Text Available This study aims at evaluating postoperative analgesic efficacy and safety of intrathecal neostigmine doses in patients under hemispinal anesthesia. After Ethics Committee approval, 48 patients sheduled for elective arthroscopic surgery.patients were randomly divided into four groups. Hemispinal block technique was performed at the lateral decubitis position. Group I received 1.4 ml hyperbaric bupivacaine plus 12.5 µg neostigmine, Group II received 1.4 ml hyperbaric bupivacaine plus 25 µg neostigmine, Group III received 1.4 ml hyperbaric bupivacaine plus 50 µg neostigmine, Group IV (control received 1.4 ml hyperbaric bupivacaine plus 0.1 ml saline. Tramadol was used for analgesia during postoperative period. Hemodynamic and respiratorial changes, time to first rescue analgesics, postoperative tramadol consumption, and advers effects were assessed. Neostigmine at these doses was found to have no effect on hemodynamic or respiratory parameters. The time first rescue analgesics were 273±47 minutes in GI, 595±47 minutes in GII, 869±49 minutes in GIII, 190±4 minutes in GIV. Postoperative tramadol consumtion in neostigmin groups was defined low in meaningful degree when compared to the control group. None of the patients in GIV had postoperative nausea-vomiting. Postoperative nausea-vomiting incidences were 8.3% (1 patient in GI, 33.3% In this study it was concluded that intrathecal neostigmine produce a dose-dependent analgesia and dose-dependent incidence of adverse effects with doses studied. Neostigmine 12.5 µg dosage was enough for providing comfortable postoperative analgesia with low adverse effect.

    Full Text Available Background: Epidural analgesia is the most effective analgesics used during childbirth but is not without its problems.In the Hospital San Juan de la Cruz of Ubeda from November 2011 we have detected 3 cases of newborn infants with signs of respiratory depression. Appeared in them: normal cardiotocographic records during childbirth, use of epidural associated with fentanyl, termination by vacuum and elevated temperature in one case.ObjectivesKnow if the neonatal adaptation to extrauterine life may be influenced by the use of epidural analgesia in childbirth. Review what role can have the rise in maternal temperature and the use of epidural fentanyl with the appearance of newborn respiratory distress.MethodsLiterature Review conducted in February of 2012 in Pubmed and the Cochrane Library, using the key words: childbirth, epidural analgesia, neonatal respiratory depression.ResultsOn the respiratory depression associated with fentanyl, a Cochrane review found indicating that newborns of mothers with an epidural, had a lower pH and were less need for administration of naloxone.On PubMed we find a review study that indicates that the respiratory depression caused by the administration of opioids via neuroaxial is rare, placing it below 1 per 1000, and a clinical case that concluded that doses of fentanyl exceeding 300 µg (approx. 5 µg/kg for 4 hours previous to childbirth, have a high risk of neonatal respiratory depression at birth.The same Cochrane review indicates that the women with epidural analgesia had increased risk of maternal fever of at least 38 ° C and a recent cohort study relates this increase in temperature with a greater likelihood of neonatal adverse events (from 37.5 ° C.ConclusionsThe studies found considered safe epidurals to the neonate and the mother, except when certain conditions are met.

    2012-05-01

    In the nineties, spinal analgesia has been described as an useful means to control pain in advanced cancer patients. The aim of this review was to update this information with a systematic analysis of studies performed in the last 10 years. 27 papers pertinent with the topic selected for review were collected according to selection criteria. Few studies added further information on spinal analgesia in last decade. Despite a lack of a clinical evidence, spinal analgesia with a combination of opioids, principally morphine, and local anesthetics may allow to achieve analgesia in patients who had been intensively treated unsuccessfully with different trials of opioids. Some adjuvant drugs such as clonidine, ketamine, betamethasone, meperidine, and ziconotide may be promising agents, but several problems have to be solved before they can be used in the daily practice. In complex pain situations, spinal analgesia should not be negated to cancer patients, and oncologists should address this group of patients to other specialists. PMID:21684173

    Epidural analgesia has become increasingly popular as a form of labour analgesia in Ireland. However obtaining true inform consent has always been difficult. Our study recruited 100 parturients who had undergone epidural analgesia for labour, aimed to determine the information they received prior to regional analgesia, and to ascertain their preferences regarding informed consent. Only 65 (65%) of patients planned to have an epidural. Knowledge of potential complications was variable and inaccurate, with less than 30 (30%) of women aware of the most common complications. Most women 79 (79%) believed that discomfort during labour affected their ability to provide informed consent, and believe consent should be taken prior to onset of labour (96, 96%). The results of this study helps define the standards of consent Irish patients expect for epidural analgesia during labour.

    Full Text Available Background: The aim of preemptive analgesia is to reduce central sensitization that arises from noxious inputs across the entire perioperative period. N-methyl d-aspartate receptor antagonists have the potential for attenuating central sensitization and preventing central neuroplasticity. Materials and Methods: Patients undergoing laparoscopic cholecystectomy were randomized into four groups of 20 patients each, who were administered the study drug intravenously 30 min before incision. Groups A, B, and C received ketamine in a dose of 1.00, 0.75 and 0.50 mg/kg, respectively, whereas group D received isotonic saline. Anesthetic and surgical techniques were standardized. Postoperatively, the degree of pain at rest, movement, and deep breathing using visual analogue scale, time of request for first analgesic, total opioid consumption, and postoperative nausea and vomiting were recorded in postanesthesia care unit for 24 h. Results: Pain scores were highest in Group D at 0 h. Groups A, B, and C had significantly decreased postoperative pain scores at 0, 0.5, 3, 4, 5, 6, and 12 h. Postoperative analgesic consumption was significantly less in groups A, B, and C as compared with group D. There was no significant difference in the pain scores among groups A, B, and C. Group A had a significantly higher heart rate and blood pressure than groups B and C at 0 and 0.5 h along with 10% incidence of hallucinations. Conclusion: Preemptive ketamine has a definitive role in reducing postoperative pain and analgesic requirement in patients undergoing laparoscopic cholecystectomy. The lower dose of 0.5 mg/kg being devoid of any adverse effects and hemodynamic changes is an optimal dose for preemptive analgesia in patients undergoing laparoscopic cholecystectomy.

    >Fundamento: El dolor posoperatorio constituye un problema muy difundido y constante en los cuidados del paciente quirúrgico. La lucha por encontrar nuevas terapéuticas para aliviar el dolor ha llevado a la fabricación y uso de gran variedad de analgésicos que son administrados por diferentes vías. Se conocen bien los efectos de los narcóticos en el recién nacido y fue la preocupación al respecto lo que motivó el interés por el uso de esos fármacos por vía epidural e intratecal en la paciente obstétrica. Objetivo: Evaluar la factibilidad del uso de morfina liofilizada por vía peridural en la operación cesárea. Métodos : Estudio de serie de casos desarrollado durante el periodo comprendido entre febrero del 2001 a agosto del 2002 en la unidad quirúrgica del Servicio de Ginecoobstetricia del Hospital Universitario ¨Dr.Gustavo Aldereguía Lima¨ de Cienfuegos, que incluyó 120 pacientes sometidas a cesárea iterativa electiva. Se analizaron variables correspondientes a tensión arterial, frecuencia cardiaca, frecuencia respiratoria durante el preoperatorio, transoperatorio y posoperatorio, comienzo del efecto anestésico y duración de este, además se analizaron las complicaciones perioperatorias, la calidad de la analgesia posoperatoria y su repercusión en el recién nacido, medida mediante el puntaje de Apgar. El procesamiento estadístico se realizó utilizando el paquete estadístico Epi Info 6. Resultados : El comienzo del efecto anestésico y el tiempo de duración de la anestesia no se modificaron con el uso de la morfina liofilizada. Los parámetros vitales se mantuvieron con valores normales en la mayoría de las pacientes durante el preoperatorio, transoperatorio y posoperatorio. Las complicaciones que se presentaron fueron: prurito, retención urinaria, náuseas y vómitos. La calidad de la analgesia resultó satisfactoria en la mayoría de las pacientes. Los valores de Apgar fueron normales en todos

    Despite widespread use of epidural analgesia during labor, no consensus has been reached among obstetric and anesthesia providers regarding its effects on breastfeeding. The purpose of this review was to examine the relationship between labor epidural analgesia and breastfeeding in the immediate postpartum period. PubMed, Cochrane Library, and Cumulative Index to Nursing and Allied Health Literature were searched for articles published in 1990 or thereafter, using the search term breastfeeding combined with epidural, labor epidural analgesia, labor analgesia, or epidural analgesia Of 117 articles, 23 described empirical studies specific to labor epidural analgesia and measured a breastfeeding outcome. Results were conflicting: 12 studies showed negative associations between epidural analgesia and breastfeeding success, 10 studies showed no effect, and 1 study showed a positive association. Most studies were observational. Of 3 randomized controlled studies, randomization methods were inadequate in 2 and not evaluable in 1. Other limitations were related to small sample size or inadequate study power; variation and lack of information regarding type and dosage of analgesia or use of other intrapartum interventions; differences in timing, definition, and method of assessing breastfeeding success; or failure to consider factors such as mothers' intention to breastfeed, social support, siblings, or the mother's need to return to work or school. It is also unclear to what extent results are mediated through effects on infant neurobehavior, maternal fever, oxytocin release, duration of labor, and need for instrumental delivery. Clinician awareness of factors affecting breastfeeding can help identify women at risk for breastfeeding difficulties in order to target support and resources effectively. PMID:27121239

    Full Text Available Existe un interés creciente por la realización de los bloqueos de nervio periférico (BNP debido a sus potenciales beneficios como los concernientes a las interacciones de los fármacos anticoagulantes y los bloqueos neuroaxiales. Los BNP de la extremidad inferior, y sobre todo, los bloqueos periféricos del nervio ciático son el pariente pobre de las técnicas de anestesia regional y, en general, son poco conocidos y por tanto poco utilizados. En este artículo se realiza una revisión de los bloqueos del plexo lumbosacro, realizando especial énfasis en los bloqueos continuos mediante catéteres para analgesia postoperatoria y para el tratamiento del dolor crónico. La utilización de anestésicos locales de larga duración de acción, asociada a un escaso bloqueo motor, como es el caso de la ropivacaína, nos permite combinar técnicas de punción única para conseguir una adecuada analgesia intraoperatoria, con las técnicas de perfusión continua para analgesia postoperatoria. Es necesario un conocimiento anatómico preciso, así como de los territorios cutáneos de inervación de las ramas del plexo lumbosacro, para la realización de estas técnicas de bloqueo. La introducción de diferentes técnicas de imagen, fundamentalmente la ultrasonografía, para la localización de las estructuras nerviosas, facilita la realización de estos bloqueos y disminuye el riesgo de lesiones de los órganos adyacentes. La realización de los bloqueos continuos de nervio periférico ofrece el beneficio de una analgesia postoperatoria prolongada, con menores efectos adversos, mayor grado de satisfacción del paciente, y una recuperación funcional más rápida después de la cirugía.There is increasing interest in peripheral nerve blocks (PNB because of potential benefits relative to interactions of anticoagulants and central neuraxial techniques.

    estudios en un área con tantas lagunas de conocimiento en nuestro medio.This is a first-time study in Brazil, which identified the relations between the analgesic standard and trauma severity. To do this, an analysis was performed in a population of 200 traffic accident victims admitted for treatment at the emergency unit of a referral hospital for trauma care in the city of São Paulo. Trauma and lesion severity were characterized by anatomic severity indexes. Based on the analysis of the analgesic therapy, analgesia standards were constructed, founded on the World Health Organization analgesic scale. The results permitted to identify the statistic association between trauma severity and distinct analgesia standards. The dissemination of these findings could serve as the basis to design analgesia protocols in trauma and improve care quality, besides encouraging the development of studies in an area with so many knowledge gaps.

    PURPOSE: This two-part review summarizes the current knowledge of physiological mechanisms, pharmacological modalities and controversial issues surrounding preemptive analgesia. SOURCE: Articles from 1966 to present were obtained from the MEDLINE databases. Search terms included analgesia, preemptive; neurotransmitters; pain, postoperative; hyperalgesia; sensitization, central nervous system; pathways, nociception; anesthetic techniques; analgesics, agents. Principal findings: In Part I of this review article, techniques and agents that attenuate or prevent central and peripheral sensitization were reviewed. In Part II, the conditions required for effective preemptive techniques are evaluated. Specifically, preemptive analgesia may be defined as an antinociceptive treatment that prevents establishment of altered central processing of afferent input from sites of injury. The most important conditions for establishment of effective preemptive analgesia are the establishment of an effective level of antinociception before injury, and the continuation of this effective analgesic level well into the post-injury period to prevent central sensitization during the inflammatory phase. Although single-agent therapy may attenuate the central nociceptive processing, multi-modal therapy is more effective, and may be associated with fewer side effects compared with the high-dose, single-agent therapy. CONCLUSION: The variable patient characteristics and timing of preemptive analgesia in relation to surgical noxious input require individualization of the technique(s) chosen. Multi-modal analgesic techniques appear more effective.

    Continuous interscalene brachial plexus blockade can provide anesthesia and analgesia in the shoulder region. Difficulty accessing the interscalene space and premature displacement of interscalene catheters may preclude their use in certain situations. We present two case reports in which a catheter was advanced from the axilla along the brachial plexus sheath to the interscalene space to provide continuous cervicobrachial plexus analgesia. In the first case report, previous neck surgery made the anatomic landmarks for performing an interscalene block very difficult. An epidural catheter was advanced from the axillary brachial plexus sheath to the interscalene space under fluoroscopic guidance. This technique provided both intraoperative analgesia for shoulder surgery as well as 24-hour postoperative analgesia by an infusion of 0.125% bupivacaine. In the second case report, a catheter was inserted in a similar fashion from the axillary to the interscalene space to provide 14 days of continuous analgesia in the management of complex regional pain syndrome. We have found that this technique allows us to secure the catheter more easily than with the traditional interscalene approach and thus prevents premature dislodgment. This approach may be a suitable alternative when either an interscalene or an infraclavicular catheter may not be inserted. PMID:11090734

    PURPOSE: This two-part review summarizes the current knowledge of physiological mechanisms, pharmacological modalities and controversial issues surrounding preemptive analgesia. SOURCE: Articles from 1966 to present were obtained from the MEDLINE databases. Search terms included: analgesia, preemptive; neurotransmitters; pain, postoperative; hyperalgesia; sensitization, central nervous system; pathways, nociception; anesthetic techniques; analgesics, agents. Principal findings: The physiological basis of preemptive analgesia is complex and involves modification of the pain pathways. The pharmacological modalities available may modify the physiological responses at various levels. Effective preemptive analgesic techniques require multi-modal interception of nociceptive input, increasing threshold for nociception, and blocking or decreasing nociceptor receptor activation. Although the literature is controversial regarding the effectiveness of preemptive analgesia, some general recommendations can be helpful in guiding clinical care. Regional anesthesia induced prior to surgical trauma and continued well into the postoperative period is effective in attenuating peripheral and central sensitization. Pharmacologic agents such as NSAIDs (non-steroidal anti-inflammatory drugs) opioids, and NMDA (N-methyl-D-aspartate) - and alpha-2-receptor antagonists, especially when used in combination, act synergistically to decrease postoperative pain. CONCLUSION: The variable patient characteristics and timing of preemptive analgesia in relation to surgical noxious input requires individualization of the technique(s) chosen. Multi-modal analgesic techniques appear most effective.

    Full Text Available Hay un elevado número de receptores opioides localizados en la sustancia gelatinosa del asta dorsal medular. La inyección epidural de opioides permite la unión de forma saturable y competitiva con estos receptores, con lo que se consigue analgesia y disminución del riesgo de efectos adversos asociados a la administración parenteral de los mismos. No obstante, es importante tener en cuenta los posibles efectos adversos que pueden aparecer, siendo la depresión respiratoria la complicación más importante. La morfina es el opioide agonista mu más utilizado para el tratamiento del dolor agudo o crónico y constituye el analgésico estándar con el que se comparan los nuevos analgésicos. El fentanilo es un agonista opioide derivado de la fenilpiperidina que posee una alta afinidad por los receptores mu, lo que le confiere una potencia analgésica 50-100 veces superior a la morfina. El tramadol es el más reciente de los opioides sintéticos empleados en España. Tiene baja afinidad por los receptores mu, kappa y delta, no obstante su potencia analgésica respecto a la morfina es 1/10 por vía parenteral y 1/30 por vía espinal. Los opioides por vía epidural se han empleado ampliamente en adultos, pero con una frecuencia mucho menor en pediatría. En este artículo se repasan los distintos estudios que han evaluado sus efectos en pediatría, haciendo referencia a la farmacocinética, consideraciones clínicas y posibles efectos adversos tras la administración de morfina, fentanilo o tramadol por vía epidural.There is a high number of opiate receptors located at the gelatinous substance of the medullar dorsal horn.

  1. Multimodal Analgesia in the Hip Fracture Patient.

    Fabi, David W

    2016-05-01

    Hip fracture is one of the most common injuries among the elderly and, because the population is aging, it is expected to remain a major clinical challenge and public health problem for the foreseeable future. The clinical importance of early mobilization and prompt participation in physical therapy after hip fracture surgery is now widely recognized. Because postoperative pain can impair mobility and delay physical therapy, much attention is now being paid to finding more effective ways of controlling pain after hip fracture. Oversedation with opioid drugs inhibits communication between the patient and the health care team, can delay ambulation and rehabilitation therapy, and may increase the probability of the patient requiring a skilled nursing facility, which adds further cost to the overall health care system. Multiple pain pathways contribute to the perception of postoperative pain, and although opioids are highly effective in blocking nociceptive pain through inhibition of the mu receptors, they do not block other pain pathways. Multimodal analgesia involves the use of several anesthetic and analgesic modalities that are strategically combined to block pain perception at different sites in the peripheral and central nervous systems. This balanced, multifaceted approach provides more effective control of postoperative pain than opioid drugs alone, allows lower doses of opioids to be used as part of the multimodal regimen (thereby reducing the risk of opioid-related adverse events and complications), and may facilitate more rapid recovery and improve certain outcome measures related to recovery time. One prospective randomized study evaluating the clinical value of multimodal pain management in elderly patients undergoing bipolar hip hemiarthroplasty found that a multimodal regimen, including preemptive pain medication and intraoperative periarticular injections, reduced pain on postoperative days 1 and 4, and reduced overall opioid use. This article describes

    1985-03-01

    Pentobarbital pretreatment reportedly either inhibits, enhances or has no effect on morphine analgesia. The effect of subanesthetic doses of sodium pentobarbital (8-12 mg kg-1, SC) delivered via a delivery system on analgesia of morphine (5 mg kg-1, SC or 1 mg kg-1, IV) acutely administered 45 min after the sodium pentobarbital pellet implantation was assessed using the warm water (55 degrees C)-induced tail-withdrawal reflex in male Wistar rats. Significant potentiation of morphine analgesia was observed in sodium pentobarbital as compared to the placebo-pelleted animals. Pharmacokinetic or dispositional factors were not involved in this potentiation, which was possibly due to the activation of the descending inhibitory control pathways of nociceptive spinal tail-withdrawal reflex by a combined interaction of two drugs at spinal and supraspinal sites of action, that mediate opiate antinociception.

    The influence of sex has been neglected in clinical studies on pain and analgesia, with the vast majority of research conducted exclusively in males. However, both preclinical and clinical studies indicate that males and females differ in both the anatomical and physiological composition of central nervous system circuits that are involved in pain processing and analgesia. These differences influence not only the response to noxious stimuli, but also the ability of pharmacological agents to modify this response. Morphine is the most widely prescribed opiate for the alleviation of persistent pain in the clinic; however, it is becoming increasingly clear that morphine is less potent in women compared to men. This review highlights recent research identifying neuroanatomical and physiological dimorphisms underlying sex differences in pain and opioid analgesia, focusing on the endogenous descending pain modulatory circuit.

    Full Text Available La analgesia epidural se ha convertido en una técnica rutinaria en el manejo perioperatorio de los pacientes quirúrgicos que se ha extendido fuera de los quirófanos y de las unidades de alta dependencia hacia las salas de hospitalización. La irrupción en este nuevo escenario ha mejorado la analgesia postoperatoria con aceptables márgenes de seguridad, lo que le ha servido para colocarse en un lugar predominante entre las pautas analgésicas de las Unidades de Dolor Agudo (UDA. La analgesia epidural con anestésicos locales y opioides frente a la sistémica con opioides ha presentado históricamente una superior eficacia analgésica, y una disminución de complicaciones derivadas de la atenuación del estrés quirúrgico y de la mejora en la función cardiorrespiratoria. Sin embargo, frente a estas ventajas la analgesia epidural también presenta inconvenientes como la hipotensión arterial o la retención urinaria, junto a las potencialmente graves derivadas del daño neurológico ocasionado por un hematoma epidural, una infección o una lesión directa del tejido nervioso. Si sus ventajas han resultado consistentes y fundamentadas, en este momento no lo parecen tanto. El avance que ha supuesto la cirugía mínimamente invasiva con altas más precoces, junto al desarrollo de estrategias multimodales, está conduciendo a un replanteamiento de la utilización de técnicas como la epidural y a una reevaluación de sus indicaciones. Las últimas evidencias nos inducen a pensar que la epidural probablemente haya tocado techo en el tratamiento del dolor postoperatorio y comenzará a perder terreno frente a otras técnicas igualmente efectivas, con menores complicaciones y efectos secundarios. Este será un proceso lento en el que deberá quedar asegurado que las alternativas analgésicas ofrecen realmente mejores resultados en cuanto a eficacia, seguridad, tolerabilidad y calidad de la recuperación desde la perspectiva del paciente

    An important aspect of adaptive stress response is the pain response suppression that occurs during or following stress exposure, which is often referred to as acute stress-induced analgesia. Dehydroepiandrosterone (DHEA) participates in the modulation of adaptive stress response, changing the HPA axis activity. The effect of DHEA on the HPA axis activity is dependent on the state and uses the same systems that participate in the regulation of acute stress-induced analgesia. The impact of DHEA on nociception has been studied; however, the effect of DHEA on stress-induced analgesia is not known. Thus, the aim of the present study was to evaluate the effect of DHEA on stress-induced analgesia and determine the best time for hormone administration in relation to exposure to stressor stimulus. The animals were stressed by restraint for 1h in a single exposure and received treatment with DHEA by a single injection before the stress or a single injection after the stress. Nociception was assessed with a tail-flick apparatus. Serum corticosterone levels were measured. DHEA administered before exposure to stress prolonged the acute stress-induced analgesia. This effect was not observed when the DHEA was administered after the stress. DHEA treatment in non-stressed rats did not alter the nociceptive threshold, suggesting that the DHEA effect on nociception is state-dependent. The injection of DHEA had the same effect as exposure to acute stress, with both increasing the levels of corticosterone. In conclusion, acute treatment with DHEA mimics the response to acute stress indexed by an increase in activity of the HPA axis. The treatment with DHEA before stress exposure may facilitate adaptive stress response, prolonging acute stress-induced analgesia, which may be a therapeutic strategy of interest to clinics.

    We report the successful use of a stellate ganglion block as part of a multi-modal postoperative analgesic regimen. Four patients scheduled for orthopaedic surgery following upper limb trauma underwent blockade of the stellate ganglion pre-operatively under ultrasound guidance. Patients reported excellent postoperative analgesia, with postoperative VAS pain scores between 0 and 2, and consumption of morphine in the first 24 h ranging from 0 to 14 mg. While these are preliminary findings, and must be confirmed in a clinical trial, they highlight the potential for stellate ganglion blockade to provide analgesia following major upper limb surgery.

    Full Text Available OBJETIVO: Um amplo corpo de evidência oriundo de estudos experimentais indica que a sepse se associa com um aumento da produção de espécies de oxigênio reativo, depleção de antioxidantes, e acúmulo de marcadores de estresse oxidativo. Além disto, a disfunção mitocondrial foi implicada na patogênese da síndrome de disfunção de múltiplos órgãos. A citrato sintase é uma enzima que se localiza no interior das células, na matriz mitocondrial, sendo uma etapa importante do ciclo de Krebs; esta enzima foi utilizada como um marcador enzimático quantitativo da presença de mitocôndrias intactas. Assim, investigamos a atividade da citrato sintase no cérebro de ratos submetidos ao modelo sepse com de ligadura e punção do ceco. MÉTODOS: Em diferentes horários (3, 6, 12, 24 e 48 horas após cirurgia de ligadura e punção do ceco, seis ratos foram sacrificados por decapitação, sendo seus cérebros removidos e dissecados o hipocampo, estriato, cerebelo, córtex cerebral e córtex pré-frontal, e utilizados para determinação da atividade de citrato sintase. RESULTADOS: Verificamos que a atividade de citrato sintase no córtex pré-frontal estava inibida após 12, 24 e 48 horas da ligadura e punção do ceco. No córtex cerebral, esta atividade estava inibida após 3, 12, 24 e 48 horas da ligadura e punção do ceco. Por outro lado a citrato sintase não foi afetada no hipocampo, estriato e cerebelo até 48 horas após a ligadura e punção do ceco. CONCLUSÃO: Considerando-se que é bem descrito o comprometimento da energia decorrente da disfunção mitocondrial na sepse, e que o estresse oxidativo desempenha um papel essencial no desenvolvimento da sepse, acreditamos que o comprometimento da energia pode também estar evolvido nestes processos. Se a inibição da citrato sintase também ocorre em um modelo de sepse, é tentador especular que a redução do metabolismo cerebral pode provavelmente estar relacionada com a

    Standard care of burn wounds consists of cleaning and debridement (removing devitalized tissue), followed by daily dressing changes. Children with burns undergo multiple, painful and anxiety-provoking procedures during wound care and rehabilitation. The goal of procedural sedation is safe and efficacious management of pain and emotional distress, requiring a careful and systematic approach. Achieving the best results needs understanding of the mechanisms of pain and the physiologic changes in burn patients, frequent evaluation and assessment of pain and anxiety, and administration of suitable pharmacological and nonpharmacological therapies. Pharmacological therapies provide the backbone of analgesia and sedation for procedural pain management. Opioids provide excellent pain control, but they must be administered judiciously due to their side effects. Sedative drugs, such as benzodiazepines and propofol, provide excellent sedation, but they must not be used as a substitute for analgesic drugs. Ketamine is increasingly used for analgesia and sedation in children as a single agent or an adjuvant. Nonpharmacological therapies such as virtual reality, relaxation, cartoon viewing, music, massage and hypnosis are necessary components of procedural sedation and analgesia for children. These can be combined with pharmacological techniques and are used to limit the use of drugs (and hence side effects), as well as to improve patient participation and satisfaction. In this article, we review the pathophysiologic changes associated with major thermal injury in children, the options available for sedation and analgesia for wound care procedures in these children and our institutional guidelines for procedural sedation.

Bupivacaine, a commonly used analgesic, has been formulated into an aqueous suspension of multivesicular liposomes that provide long-lasting analgesia for up to 72 hours, while avoiding the adverse side effects of opioids. The increased efficacy of liposomal extended-release bupivacaine, compared to bupivacaine hydrochloride, has promoted its usage in a variety of surgeries including hemorrhoidectomy, bunionectomy, inguinal hernia repair, total knee arthroplasty, and augmentation mammoplasty. However, like other bupivacaine formulations, the liposomal extended-release bupivacaine does have some side effects.

Gamma irradiation attenuates the acute analgesic action of i.c.v. injected morphine in mice. This study was done to investigate the effect of-irradiation on the analgesia produced by i.c.v. injected morphine and endorphin in male ICR mice. In one group, mice were exposed to whole-body irradiation at a dose of 5 Gy from a {sup 60}Co source and the analgesic effects were tested 5, 30, 60, 90 and 180 min after irradiation using the acetic acid-induced writhing test. The analgesic effect was produced time-dependently and reached its maximum at 90 min after irradiation. Thus, time was fixed in the following studies. In another group, mice were irradiated with 5 Gy and tested 90 minutes later for analgesia produced by i.c.v. administration of morphine or endorphin. Irradiation significantly potentiated the analgesia produced by endorphin. However, the antinociception produced by morphine was not affected by irradiation. These results support the hypothesis that morphine and endorphin administered supraspinally produce antinocieception by different neuronal mechanisms.

    Steagall, Paulo V M; Monteiro-Steagall, Beatriz P

    2013-08-01

    Adequate pain relief is usually achieved with the simultaneous use of two or more different classes of analgesics, often called multimodal analgesia. The purpose of this article is to highlight the use of perioperative multimodal analgesia and the need to individualize the treatment plan based on the presenting condition, and to adjust it based on the response to analgesia for a given patient. This case series presents the alleviation of acute pain in three cats undergoing different major surgical procedures. These cases involved the administration of different classes of analgesic drugs, including opioids, non-steroidal anti-inflammatory drugs, tramadol, ketamine, gabapentin and local anesthetics. The rationale for the administration of analgesic drugs is discussed herein. Each case presented a particular challenge owing to the different cause, severity, duration and location of pain. Pain management is a challenging, but essential, component of feline practice: multimodal analgesia may minimize stress while controlling acute perioperative pain. Individual response to therapy is a key component of pain relief in cats. PMID:23382595

    BACKGROUND AND OBJECTIVE: The last 25 years have seen changes in the management of epidural analgesia for labour, including the advent of low-dose epidural analgesia, the development of new local anaesthetic agents, various regimes for maintaining epidural analgesia and the practice of combined spinal-epidural analgesia. We conducted a survey of Irish obstetric anaesthetists to obtain information regarding the conduct and management of obstetric epidural analgesia in Ireland in 2005. The specific objective of this survey was to discover whether new developments in obstetric anaesthesia have been incorporated into clinical practice. METHODS: A postal survey was sent to all anaesthetists with a clinical commitment for obstetric anaesthesia in the sites approved for training by the College of Anaesthetists, Ireland. RESULTS: Fifty-three per cent of anaesthetists surveyed responded. The majority of anaesthetists (98%) use low-dose epidural analgesia for the maintenance of analgesia. Only 11% use it for test-dosing and 32% for the induction of analgesia. The combined spinal-epidural analgesia method is used by 49%, but two-thirds of those who use it perform fewer than five per month. Patient-controlled epidural analgesia was in use at only one site. CONCLUSION: It appears that Irish obstetric anaesthetists have adopted the low-dose epidural analgesia trend for the maintenance of labour analgesia. This practice is not as widespread, however, for test dosing, the induction of analgesia dose or in the administration of intermittent epidural boluses to maintain analgesia when higher concentrations are used. Since its introduction in 2000, levobupivacaine has become the most popular local anaesthetic agent.

    Full Text Available BACKGROUND: Clonidine is an α 2 adrenoreceptor agonist that has been shown to effectively prolong the duration of analgesia when administered intrathecally or in the epidural space along with local anaesthetic. AIMS AND OBJECTIVE: This study was designed to evaluate the effect of two different doses of intrathecal clonidine (37.5 μg and 75 μg on the duration of analgesia and side effects produced by hyperbaric bupivacaine 0.5%. MATERIALS AND METHODS : A prospective hospital based, randomized and double blind study. Selected 75 patients who was scheduled for elective below umbilical surgeries were randomly allocated to one of three groups. Group I (n=25, control group received 3ml hyperbaric bupivacaine, Group II (n=25 3ml hyperbar ic bupivacaine + 37.5 μg clonidine and Group III (n=25 3 ml hyperbaric bupivacaine + 75μg clonidine intrathecally. Total volume (4ml remained constant by adding sterile water. Data were analyzed by using SPSS software ver.18. RESULTS: The (mean ±SD dura tion of analgesia was found to be 171.3±6.37 mins in Group I, 217.7±7.01 mins in Group II and 257.1±6.50 mins in Group III (p<0.05. It shows that 37.5  g & 75  g intrathecal clonidine increases the duration of analgesia of 15mg hyperbaric bupivacaine by abo ut 46 mins & 86 mins respectively. The addition of intrathecal clonidine upto 75 μg does not cause any significant major side effect except mild sedation, without an increase in incidence of hypotension, bradycardia and respiratory depression. CONCLUSION: Intrathecal clonidine (37.5  g & 75  g as an adjuvant to hyperbaric bupivacaine 0.5% prolong the duration of analgesia in a dose dependent manner without increase in incidence of significant side effects

  4. Effect of epidural analgesia on labor and its outcomes

    International Nuclear Information System (INIS)

    Epidural analgesia is an effective and popular way to relieve labour pain but it may interfere with normal mechanism of labour. The objective of this study was to evaluate the outcome of labour in women with effective epidural analgesia in terms of duration of labour, mode of delivery and neonatal outcome. Methods: This was a quasi-experimental study conducted in the Department of Obstetrics and Gynaecology, Shaikh Zayed Federal Postgraduate Medical Institute and Hospital, Lahore. One hundred pregnant women were selected by non-probability convenient sampling method. Subjects were divided into two groups of 50 each as per convenience. Patients of any gravidity at term from 37-41 weeks were included in the sample. Epidural analgesia was applied to group B and distilled water to group A at the lumber region and the progress of labour, mode of delivery and effects on Apgar scores of neonates were evaluated. Out of hundred patients, 77 had normal duration of second stage while 23 had prolonged second stage. Among them, 18 patients (36%) were in epidural group and 5 patients (10%) in non-epidural group, while 4 patients (8%) in epidural group developed intra-partum complications; whereas among non-epidural group had such complications. 65 patients had spontaneous vaginal delivery while 35 patients had instrumental delivery. Among them 29 patients (58%) were in epidural group while only 6 patients (12%) were in non-epidural group. Babies born had Apgar score 5/10 (21.8%), 6/10 (59.4%) and 7/10 (17.8%) at 1 minute and 8/10 (74.3%) and 9/10 (24.8%) at 5 minutes in both groups and none of them needed bag and mask resuscitation. Conclusion: Epidural analgesia does prolong the duration of second stage of labour and increases the instrumental delivery rate. Neonatal outcome is satisfactory while only a few intra-partum complications are found with epidural analgesia. (author)

    Full Text Available Hay un elevado número de receptores opioides localizados en la sustancia gelatinosa del asta dorsal medular. La inyección epidural de opioides permite la unión de forma saturable y competitiva con estos receptores, con lo que se consigue analgesia y disminución del riesgo de efectos adversos asociados a la administración parenteral de los mismos. No obstante, es importante tener en cuenta los posibles efectos adversos que pueden aparecer, siendo la depresión respiratoria la complicación más importante. La morfina es el opioide agonista mu más utilizado para el tratamiento del dolor agudo o crónico y constituye el analgésico estándar con el que se comparan los nuevos analgésicos. El fentanilo es un agonista opioide derivado de la fenilpiperidina que posee una alta afinidad por los receptores mu, lo que le confiere una potencia analgésica 50-100 veces superior a la morfina. El tramadol es el más reciente de los opioides sintéticos empleados en España. Tiene baja afinidad por los receptores mu, Kappa y delta, no obstante su potencia analgésica respecto a la morfina es 1/10 por vía parenteral y 1/30 por vía espinal. Los opioides por vía epidural se han empleado ampliamente en adultos, pero con una frecuencia mucho menor en pediatría. En este artículo se repasan los distintos estudios que han evaluado sus efectos en pediatría, haciendo referencia a la farmacocinética, consideraciones clínicas y posibles efectos adversos tras la administración de morfina, fentanilo o tramadol por vía epidural.A large number of opioid receptors are located in the substantia gelatinosa of the medullar dorsal horn. Epidurally injected opioids bind with these receptors in a competitive and saturable manner causing analgesia and a lower risk of side effects as compared with its parenteral administration.

    Cocaine hydrochloride (50 mg) pellets implanted subcutaneously in male Wistar rats potentiated the analgesia of morphine, levorphanol, methadone and buprenorphine as measured by the tail-withdrawal test. Potentiated opiate analgesia was abolished by naloxone and further enhanced by desipramine and phenoxybenzamine. Yohimbine, alpha-methyl p-tyrosine, haloperidol, zimelidine, methysergide, p-chlorophenylalanine produced no significant effect on potentiated opiate analgesia. Pseudo-cocaine (dextro-cocaine), which is several-fold less potent than cocaine as an inhibitor of noradrenaline and dopamine reuptake in the CNS, had no significant effect on opiate analgesia. Analgesia produced by low doses of baclofen, a GABA agonist, was also not potentiated by cocaine. This study suggests a predominant role for noradrenaline in the stereospecific potentiation of opiate analgesia by cocaine. PMID:3822492

    If it is generally accepted that adequate postoperative pain relief will improve outcome from surgery, several controlled trials demonstrated this only for lower body surgical procedures with epidural and spinal anesthetics. Important effects on outcome were not shown when postoperative opioids...... were administered with patient controlled (PCA) or epidural techniques. However, the most optimal pain relief seems to be best achieved with balanced analgesia techniques using combinations of epidural opioids and local anesthetics and systemic non-steroidal antiinflammatory drugs.

    Full Text Available The study investigates parturients’ satisfaction with intrapartum analgesia. It aims to assess their opinions about hospital and health staff involved in delivery, besides investigating emotional control, locus control and bond between mothers and their newborn infants. A multidimensional approach has been used to investigate the variable of woman as a person, the variable of context and the variable of bond with the newborn infant. The study was conducted according to a quasi-experimental design, with a control group. The study was performed within the Analgesia and Intensive Care Operational Unit of the Maternal-Infant Department of the P. Giaccone University General Hospital of Palermo. It involved 60 women subdivided into two groups of 30 women each, the experimental group (women who requested intrapartum analgesia called the A group, and the control group (women who refused it called the B group. The following tools were administered: the STAI-Y (State-Trait Anxiety Inventory, form Y scale; the Depression Questionnaire of CBA (Cognitive Behavioural Assessment scale; the Locus of Control questionnaire; and an interview designed for the purpose. The experimental A group women exhibited lower levels of state anxiety and depression post-partum than those of the control B group; moreover, the women in the A group exhibited higher levels of external locus of control and evaluated delivery more positively than those of the B group. There were no significant differences with regard to the relationship with their newborn infants. The study shows that intrapartum analgesia provides hospitals with the possibility to satisfy women’s needs for safety and well-being.

    Full Text Available Epidural anesthesia and analgesia is widely used to manage major abdominal surgery, but its effects in managing patients submitted to esophagoplasty are still debated. The aim of this study was to assess the influence of thoracic epidural anaesthesia on postoperative respiratory function, digestive complications and postoperative stress in patients with esophagoplasty. Twenty-six patients were admitted in a prospective study. The patients were divided into two groups: fourteen were in group A, and received general anaesthesia for esophagoplasty, and twelve were in group B, and received general anaesthesia combined with epidural thoracic anaesthesia and postoperative epidural thoracic analgesia for the same surgery procedure. When compare the two groups, the outcomes were better in group B: the rate of postoperative pneumonia was lowered from 35,7% to 16,7%, the postoperative mecanical ventilation under six hours was increased from 21,43% to 100%, the incidence of adult respiratory detrease syndrome was decreased from 28,5% to 8,3%, the digestive recovery after four days was increased from 57,1% to 75%. The cortizolemia was also lowered at six hours from 52mg% to 23mg%, and at 24 hours, from 22 to 11mg%. Identically, the sanguine lactate at four hours decreased from 6 to 3 mEq%. In conclusion, this study suggest that patients undergoing esophagoplasty will receive substantial benefit from combined general and epidural anesthesia with continuing postoperative epidural analgesia.

    Full Text Available Patient controlled epidural analgesia (PCEA is a well established technique for pain relief during labor. But the inclusion of continuous background infusion to PCEA is controversial. The aim of this study was to assess whether the use of continuous infusion along with PCEA was beneficial for laboring women with regards to quality of analgesia, maternal satisfaction and neonatal outcome in comparison to PCEA alone. Fifty five parturients received epidural bolus of 10ml solution containing 0.125% bupivacaine +2 ìg.ml-1 of fentanyl. For maintenance of analgesia the patients of Group PCEA self administered 8 ml bolus with lockout interval of 20 minutes of above solution on demand with no basal infusion. While the patients of Group PCEA + CI received continuous epidural infusion at the rate of 10 ml.hr-1 along with self administered boluses of 3 ml with lockout interval of 10 minutes of similar epidural solution. Patients of both groups were given rescue boluses by the anaesthetists for distressing pain. Verbal analogue pain scores, incidence of distressing pain, need of supplementary/rescue boluses, dose of bupivacaine consumed, maternal satisfaction and neonatal Apgar scores were recorded. No significant difference was observed between mean VAS pain scores during labor, maternal satisfaction, mode of delivery or neonatal Apgar scores. But more patients (n=8 required rescue boluses in PCEA group for distressing pain. The total volume consumed of bupivacaine and opioid was slightly more in PCEA + CI group. In both the techniques the highest sensory level, degree of motor block were comparable& prolongation of labor was not seen. It was concluded that both the techniques provided equivalent labor analgesia, maternal satisfaction and neonatal Apgar scores. PCEA along with continuous infusion at the rate of 10 ml/ hr resulted in lesser incidence of distressing pain and need for rescue analgesic. Although this group consumed higher dose of bupivacaine

Therefore, identification of appropriate experimental pain models is critical for our understanding of opioid effects with the potential to improve treatment. Objectives: The aim was to explore and compare various pain models to morphine analgesia in healthy volunteers. Methods: The study was a double-blind, randomized, two-way crossover study. Thirty-nine healthy participants were included and received morphine 30 mg (2 mg/mL as oral solution or placebo. To cover both tonic and phasic stimulations, a comprehensive multi-modal, multi-tissue pain-testing program was performed. Results: Tonic experimental pain models were sensitive to morphine analgesia compared to placebo: muscle pressure (F=4.87, P=0.03, bone pressure (F=3.98, P=0.05, rectal pressure (F=4.25, P=0.04, and the cold pressor test (F=25.3, P<0.001. Compared to placebo, morphine increased tolerance to muscle stimulation by 14.07%; bone stimulation by 9.72%; rectal mechanical stimulation by 20.40%, and reduced pain reported during the cold pressor test by 9.14%. In contrast, the more phasic experimental pain models were not sensitive to morphine analgesia: skin heat, rectal electrical stimulation, or rectal heat stimulation (all P>0.05.

    Purpose Modern neuraxial labour analgesia reflects a shift in obstetrical anesthesia thinking – away from a simple focus on pain relief towards a focus on the overall quality of analgesia. However, advances in the methods used to measure outcomes have not kept pace with clinical progress, and these approaches must evolve to facilitate meaningful assessment of the advances provided towards the quality of analgesia. Developing a tool to measure the quality of neuraxial labour analgesia that res...

    Full Text Available Background: Spinal analgesia is one of the effective and rapid methods for labor. It is not commonly used because of short duration of analgesia and motor block, which limits mother's force in labor progression. We attempted to prolong duration and quality of analgesia by adding Epinephrine.Methods: In this quasi-experimental study 90 pregnant women gravid II and III who referred to Motazedi and Imam Reza Educational & Medical Centers were recruited and divided into two groups of case and control (45 subjects in each group. The case group received spinal analgesia using Sufentanil and Bupivacaine, and Epinephrine while the control group received Sufentanil and Bupivacaine. Data including feeling of pain, motor block, duration of analgesia, fetal heart rate, nausea and vomiting, blood pressure was collected and analyzed using chi-square and t test. Results: duration of analgesia and vomiting were significantly increased in the case group. (p=0.001, p=0.01 respectively. Hemodynamic status in mothers and Apgar score of neonates were not significantly different between two groups.Conclusion: It seems that adding Epinephrine to Sufentanil and Bupivacaine could increase analgesia duration without altering in sensory level although could increase nausea and vomiting its recommended in labor analgesia.

    Full Text Available Background: Epidural analgesia is a central nerve block technique achieved by injection of a local anaesthetic close to the nerves that transmit pain and is widely used as a form of pain relief in labor. Epidural analgesia is the most effective method of pain relief during labor. But unfortunately in India incidence of painless labor by epidural analgesia is very rare even in these days. The aim of our study was to study the acceptance of epidural analgesia at a tertiary care centre. Methods: The present study was conducted in department of obstetrics and gynaecology UISEMH, Kanpur over the period from May 2012 to May 2013. The study was conducted on 98 patients who were counselled regarding the adoption of epidural analgesia as painless labour and out of these 50 patients opted for epidural analgesia. Results: In our present study the acceptance was greater in primigravida (72.43% as compared to multigravida (20%. In our society social reason was the common cause for non-acceptance in primigravida (87.5%. The majority of patients belonged to middle socioeconomic status (52% and more number of educated patients opted for epidural analgesia. Conclusions: It was found that increased awareness can lead to increased acceptance of epidural analgesia. [Int J Reprod Contracept Obstet Gynecol 2014; 3(4.000: 1087-1089

    Full Text Available ABSTRACT INTRODUCTION: The currently common musculoskeletal disorders have been increasingly treated surgically, and the pain can be a limiting factor in postoperative rehabilitation. RATIONALE: Patient controlled analgesia (PCA controls pain, but its adverse effects can interfere with rehabilitation and in the patient discharge process. This study becomes important, since there are few studies evaluating this correlation. OBJECTIVES: To compare the outcomes of patients who used and did not use patient controlled analgesia in postoperative orthopedic surgery with respect to pain, unscheduled need for O2 (oxygen, and time of immobility and in-hospital length of stay. METHODS: This is an observational, prospective study conducted at Hospital Abreu Sodré from May to August 2012. The data was daily obtained through assessments and interviews of patients undergoing total hip arthroplasty (THA and total knee arthroplasty (TKA, thoracolumbar spine arthrodesis (long PVA, cervical spine arthrodesis (cervical AVA and lumbar spine arthrodesis (lumbar PVA. RESULTS: The study showed some differences between groups, namely: the painful level was higher in the group undergoing lumbar PVA without PCA compared with the group with PCA (p = 0.03 and in the group of long PVA without PCA in the early postoperative period. This latter group used O2 for a longer time (p = 0.09. CONCLUSION: In this study, PCA was useful for analgesia in patients undergoing lumbar PVA and probably would have influenced the usage time of O2 in the group of long PVA in face of a larger sample. The use of PCA did not influence the time of leaving the bed and the in-hospital length of stay for the patients studied.

    2012-04-01

    The optimal form of post-operative analgesia in hip and knee arthroplasty is still debated. Traditionally, patient-controlled analgesia and epidural anaesthesia were used. Potential side-effects such as nausea, confusion, urinary retention, hypotension and immobility have resulted in the emergence of newer techniques that limit opioid use. Peripheral nerve blockade provides excellent analgesia but limits patient ability to ambulate in the immediate post-operative period. Local infiltrative analgesia (LIA) is an emerging technique that has shown to provide superior analgesia, higher patient satisfaction and earlier discharge from hospital when compared to some of the more traditional methods. This review article highlights the advantages of LIA in hip and knee arthroplasty surgery. We describe the technique used, including additional measures that aid early ambulation and discharge from hospital in this cohort of patients. PMID:22696983

    7,500 deliveries occurred from the date of opening of the Maternity Hospital Jean-Rostand. 3,500 of these were conducted under epidural anaesthesia. At different stages prospective studies were carried out to recall the effect of adding fentanyl to bupivacaine when the epidural injection was made. A pharmacokinetic study. This shows that the levels in the mother and the fetus begin to coincide more with the number of doses that are given and pass from 0.3 after 50 micrograms have been administered to 0.5 after 100 micrograms have been administered and 0.7 after 150 micrograms have been administered. The fetal levels are far lower than those required to depress respiration. The half life of distribution through the circulation has been worked out at 4 minutes and the half for elimination of the drug at 460 minutes. The maternal levels show great fluctuations and late alterations. Analgesia is earlier, more complete and more prolonged when fentanyl is added. Fentanyl also masks irregularities. Undesirable effects such as tiredness, pruritus, nausea, vomiting and urinary retention occur infrequently and last only for short periods of time. No mother had respiratory depression. The doses of bupivacaine that had to be given were as a whole less when fentanyl was added. In 40% of cases it only required one injection to achieve analgesia throughout the whole labour. The length of labour and the number of caesarean operations carried out did not change.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:3584862

    Recently, regional anaesthesia in children has generated increasing interest. But single injection techniques have a limited duration of postoperative analgesia. Then, continuous peripheral nerve blocks have taken an important position in the anaesthetic arsenal, allowing an effective, safe and prolonged postoperative pain management. As adults, indications for continuous peripheral nerve blocks depend on the analysis of individual benefits/risks ratio. Main indications are intense postoperative pain surgical procedures, with or without postoperative rehabilitation, and complex regional pain syndrome. Contraindications to these procedures are rather similar to those in adults, plus parental and/or children refusal. Continuous peripheral nerve blocks are usually performed under general anaesthesia or sedation in children, and require appropriate equipment in order to decrease the risk of nerve injury. New techniques, such as transcutaneous nerve stimulation or ultrasound guidance, appeared to facilitate nerve and plexus approach identification in paediatric patients. Nevertheless, continuous peripheral nerve block may theoretically mask a compartment syndrome after trauma surgical procedures. Finally, ropivacaine appears to be the most appropriate drug for continuous peripheral nerve blocks in children, requiring low flow rates and concentrations of local anaesthetic. These techniques may facilitate early ambulation by an improved pain management or even postoperative analgesia at home with disposable pumps. One might infer from the current review that excellent pain relief coupled with a reduction of side effects would contribute to improve the quality of life and to decrease the frequency of disabling behavioural modifications in children, sometimes psychologically injured by hospital stay and postoperative pain.

    Full Text Available Abstract Background Most women use some method of pain relief during labour. There is extensive research evidence available of pharmacological pain relief during labour; however this evidence is not readily available to pregnant women. Decision aids are tools that present evidence based information and allow preference elicitation. Methods We developed a labour analgesia decision aid. Using a RCT design women either received a decision aid or a pamphlet. Eligible women were primiparous, ≥ 37 weeks, planning a vaginal birth of a single infant and had sufficient English to complete the trial materials. We used a combination of affective (anxiety, satisfaction and participation in decision-making and behavioural outcomes (intention and analgesia use to assess the impact of the decision aid, which were assessed before labour. Results 596 women were randomised (395 decision aid group, 201 pamphlet group. There were significant differences in knowledge scores between the decision aid group and the pamphlet group (mean difference 8.6, 95% CI 3.70, 13.40. There were no differences between decisional conflict scores (mean difference -0.99 (95% CI -3.07, 1.07, or anxiety (mean difference 0.3, 95% CI -2.15, 1.50. The decision aid group were significantly more likely to consider their care providers opinion (RR 1.28 95%CI 0.64, 0.95. There were no differences in analgesia use and poor follow through between antenatal analgesia intentions and use. Conclusions This decision aid improves women's labour analgesia knowledge without increasing anxiety. Significantly, the decision aid group were more informed of labour analgesia options, and considered the opinion of their care providers more often when making their analgesia decisions, thus improving informed decision making.

Opportunities exist to improve pain care through increased understanding of how dynamic epigenomic remodeling shapes injury, illness, pain, and treatment response. Tightly regulated alterations of the DNA-histone chromatin complex enable cells to control transcription, replication, gene expression, and protein production. Pathological alterations to chromatin shape the ability of the cell to respond to physiologic and environmental cues leading to disease and reduced treatment effectiveness. This review provides an overview of critical epigenetic processes shaping pathology and pain, highlights current research support for the role of epigenomic modification in the development of chronic pain, and summarizes the therapeutic potential to alter epigenetic processes to improve health outcomes.

Recently, ideological patrons such as ecofeminism have feed a critical mind in the woman who is going to give birth. In this bibliographic review we don’t approach a reliable and definitive conclusion, due to the bias and lack of scientific rigour of some studies and the doubtful methodological reliability and generalization of others.This way, we conclude the need to make a tolerant effort on the part of everyone, just as researching and assuming on the services portfolio (if needed alternative techniques such as combined spinal-epidural analgesia, sterile water injections, water immersion, acupuncture, hypnosis, etc.

    Development of analgesic tolerance and withdrawal-induced pain enhancement present serious difficulties for the use of opioids for pain control. Although neuronal mechanisms to account for these phenomena have been sought for many decades, their bases remain unresolved. Within the past four years, a novel non-neuronal candidate has been uncovered that opposes acute opioid analgesia and contributes to development of opioid tolerance and tolerance-associated pain enhancement. This novel candidate is spinal cord glia. Glia are important contributors to the creation of enhanced pain states via the release of neuroexcitatory substances. New data suggest that glia also release neuroexcitatory substances in response to morphine, thereby opposing its effects. Controlling glial activation could therefore increase the clinical utility of analgesic drugs. PMID:16246435

    Tolerance to morphine analgesia was induced in male Sprague-Dawley rats by s.c. implantation of a morphine base pellet (75 mg) on the first and second day and determining the magnitude of tolerance 72 h after the first implant by s.c. injection of a test dose of morphine (5 mg/kg). Implantation of a cocaine hydrochloride pellet (25 mg), concurrently with morphine pellets or of a cocaine hydrochloride (50 mg) pellet after the development of tolerance, blocked both the development and expression of morphine analgesic tolerance. In morphine-pelleted animals pretreatment for 3 days with desipramine or zimelidine or phenoxybenzamine but not haloperidol produced no significant morphine tolerance. Pretreatment with a combination of desipramine and zimelidine, however, was as effective as cocaine in blocking morphine tolerance. Alpha-Methyl-p-tyrosine methyl ester counteracted the effect of cocaine in blocking morphine tolerance and potentiated the tolerance development. Blockade of morphine tolerance by cocaine was reinforced and facilitated by pretreatment with fenfluramine or p-chlorophenylalanine ethyl ester and to a lesser extent by clonidine and haloperidol. Acute administration of fenfluramine or zimelidine or a combination of desipramine and zimelidine or alpha-methyl-p-tyrosine methyl ester or p-chlorophenylalanine ethyl ester did not significantly affect morphine analgesia. The study suggests an important role of the concomitant depletion of both central noradrenaline and serotonin in the blockade of morphine tolerance by cocaine and stresses the importance of the counter-balancing functional relationship between these two neurotransmitters in the central nervous system.

    Full Text Available Background: Total knee arthroplasty represents one of the most painful surgeries. The aim of the study was to compare analgesia and adverse effects of intrathecal (IT ketorolac versus IT morphine, versus the combination of IT ketorolac and morphine. Materials and Methods: After ethical approval and patient consent, 80 patients undergoing knee arthroplasty were randomized to one of 4 groups. All groups received 15 mg IT bupivacaine plus IT test drug (2 ml. The control group (CG received saline as IT test drug. The morphine group (MG received IT 200 g morphine, the ketorolac group (KG IT 2 mg ketorolac and the morphine-ketorolac group (MKG 200 g morphine + 2 mg ketorolac as test drugs. Pain and adverse effects were evaluated. P < 0.05 was considered significant. Results: The MG and KG were similar in their times to time to first rescue analgesic (440 ± 38 min and 381 ± 44 min, respectively. Both groups were longer when compared to the CG (170 ± 13 min (P < 0.01. The MG and KG had lesser ketoprofen consumption compared to the CG (P < 0.05. The time to first rescue analgesic was longer to the MKG (926 ± 222 min (15 h compared to CG (P < 0.001 and to the MG and the KG (P < 0.01. MKG displayed lesser ketoprofen consumption compared to MG and KG (P < 0.05 and to the CG (P < 0.02. Conclusions: The data suggest a role for spinal ketorolac and morphine in orthopaedic surgery because this combination of agents provided 15 h of analgesia compared to 7 h after each drug alone, with no significant side-effects.

    The effects of sophrology and epidural analgesia on early relationship between the mother and her child were studied on a simple of 190 deliveries. The mothers were observed during and just after delivery. Mothers who had been separated from their child before the end of the observation were excluded from the study. The patients had the choice between epidural analgesia or prenatal care with sophrology. Participation to prenatal courses has statistically a positive effect on the relation between the mother and her child (p less than 0.01). Instead, epidural analgesia and posture have very limited effect on this factor. However, a trend to more interaction is found in multipari and patients who didn't choose epidural analgesia.

    Buprenorphine has long been classified as a mu analgesic, although its high affinity for other opioid receptor classes and the orphanin FQ/nociceptin ORL1 receptor may contribute to its other actions. The current studies confirmed a mu mechanism for buprenorphine analgesia, implicating several subsets of mu receptor splice variants. Buprenorphine analgesia depended on the expression of both exon 1-associated traditional full length 7 transmembrane (7TM) and exon 11-associated truncated 6 transmembrane (6TM) MOR-1 variants. In genetic models, disruption of delta, kappa1 or ORL1 receptors had no impact on buprenorphine analgesia, while loss of the traditional 7TM MOR-1 variants in an exon 1 knockout (KO) mouse markedly lowered buprenorphine analgesia. Loss of the truncated 6TM variants in an exon 11 KO mouse totally eliminated buprenorphine analgesia. In distinction to analgesia, the inhibition of gastrointestinal transit and stimulation of locomotor activity were independent of truncated 6TM variants. Restoring expression of a 6TM variant with a lentivirus rescued buprenorphine analgesia in an exon 11 KO mouse that still expressed the 7TM variants. Despite a potent and robust stimulation of (35) S-GTPγS binding in MOR-1 expressing CHO cells, buprenorphine failed to recruit β-arrestin-2 binding at doses as high as 10 µM. Buprenorphine was an antagonist in DOR-1 expressing cells and an inverse agonist in KOR-1 cells. Buprenorphine analgesia is complex and requires multiple mu receptor splice variant classes but other actions may involve alternative receptors. PMID:27223691

  1. TRPM8 is the principal mediator of menthol-induced analgesia of acute and inflammatory pain.

    Menthol, the cooling natural product of peppermint, is widely used in medicinal preparations for the relief of acute and inflammatory pain in sports injuries, arthritis, and other painful conditions. Menthol induces the sensation of cooling by activating TRPM8, an ion channel in cold-sensitive peripheral sensory neurons. Recent studies identified additional targets of menthol, including the irritant receptor, TRPA1, voltage-gated ion channels and neurotransmitter receptors. It remains unclear which of these targets contribute to menthol-induced analgesia, or to the irritating side effects associated with menthol therapy. Here, we use genetic and pharmacological approaches in mice to probe the role of TRPM8 in analgesia induced by L-menthol, the predominant analgesic menthol isomer in medicinal preparations. L-menthol effectively diminished pain behavior elicited by chemical stimuli (capsaicin, acrolein, acetic acid), noxious heat, and inflammation (complete Freund's adjuvant). Genetic deletion of TRPM8 completely abolished analgesia by L-menthol in all these models, although other analgesics (acetaminophen) remained effective. Loss of L-menthol-induced analgesia was recapitulated in mice treated with a selective TRPM8 inhibitor, AMG2850. Selective activation of TRPM8 with WS-12, a menthol derivative that we characterized as a specific TRPM8 agonist in cultured sensory neurons and in vivo, also induced TRPM8-dependent analgesia of acute and inflammatory pain. L-menthol- and WS-12-induced analgesia was blocked by naloxone, suggesting activation of endogenous opioid-dependent analgesic pathways. Our data show that TRPM8 is the principal mediator of menthol-induced analgesia of acute and inflammatory pain. In contrast to menthol, selective TRPM8 agonists may produce analgesia more effectively, with diminished side effects. PMID:23820004

    This randomized study was designed to compare the effectiveness of bilateral interpleural analgesia with lumbar epidural analgesia, on postoperative pain relief in upper abdominal surgery. The studied patients were randomely allocated into either interpleural group "IP" (n = 15) or epidural group "EP" (n = 15). In "IP" group, preanesthetic bilateral interpleural block was done using a mixture of bupivacaine 0.5% (0.8 mg/kg) and 2 mg morphine diluted to 50 ml saline for each side. In "EP" group, the same mixture-diluted in 20 ml saline-was injected in the epidural space (L2-3). The general anesthetic technique was the same in both groups. Hemodynamic, gasometric, verbal pain score (VPS) values and complications were compared in both techniques. Heart rate (HR) and mean arterial pressure (MAP) readings were in the accepted normal range in the perioperative period although significant lower readings were detected in "EP" group. No significant differences were displayed in blood gasometric variables between the two groups. There were considerable level of analgesia in both groups in the postoperative period although "EP" analgesia was superior to "IP". More pain free patients (9 versus 4) and significant lower consumption of nalbuphine were detected in "EP" group. The results of this study indicate that bilateral "IP" analgesia may offer a satisfactory analgesia for upper abdominal surgery when the use of other analgesic techniques may be contraindicated.

    Full Text Available Resumen La metformina es un medicamento indicado para el tratamiento de la diabetes mellitus tipo II con una función renal normal. Ha sido usada, sin la aprobación de la Administración de Drogas y Alimentos de los EEUU, en pacientes con el síndrome del ovario poliquístico, como regulador del trastorno menstrual, tratamiento del hirsutismo e inductor de ovulación. Desde 1980, Burghen y colaboradores señalaron la asociación entre el hiperandrogenismo y la hiperinsulinemia en el síndrome del ovario poliquístico. El exceso de andrógenos, resultado del aumento de la insulina, deteriora la acción de esta. Los efectos de la metformina en la disminución de la glucosa son consecuencia de una reducción en la producción de glucosa hepática y un aumento en su empleo. Este medicamento incrementa la mayoría de las acciones biológicas de la insulina en personas con resistencia a la insulina preexistente y disminuye la absorción intestinal de glucosa. Se concluye que la metformina es útil en la regulación el ciclo menstrual en comparación con el placebo; no es un tratamiento de primera elección en el hirsutismo y su uso como monoterapia en la inducción de la ovulación no demuestra sustancialmente mejoría en la tasa de embarazo clínico. La evidencia señala que la metformina asociada con el citrato de clomifeno induce la ovulación y mejora la tasa de embarazo clínico.

    We wanted to evaluate the usefulness of modified intravenous analgesia for the management of pain during uterine artery embolization for leiomyomata. Between April 2004 and July 2004, 15 patients with symptomatic fibroids underwent uterine artery embolization and pain management. Except the three patients for whom the Visual Analogue Scale (VAS) score was not obtained, twelve patients were included in this study. For pain management, epidural PCA (Patient Controlled Analgesia) was used in two patients, intravenous PCA was used in two patients and modified intravenous analgesia injection was used in eight patients. For all the patients, we used the 2.8 Fr coaxial microcatheter and 500-710 {mu} m PVA particles for the embolic materials. The protocol of the modified intravenous analgesia injection was as follow, 1) prior to femoral artery puncture, 30 mg of ketorolac tromethamine (Tarasyn)was injected via an intravenous route. 2) At the time that the one side uterine artery embolization was finished, normal saline mixed 150 mg meperidine (Demerol) was administered through the side port of the intravenous line that was used for hydration. 3) Additional ketorolac tromethamine 30 mg was injected after 6 hour. The VAS score and side effects were then checked. After 12 hours, the VAS score was rechecked. If the VAS score was above 4, this was considered as failure of pain management. The VAS scores, complications and side effects for the modified intravenous analgesia injection were compared with that of IV PCA and epidural PCA. The average VAS score of the modified intravenous analgesia injection, intravenous PCA and epidural PCA was 1.4, 1 and 0, respectively; the number of additional intramuscular injections of analgesia was 0.5, 0.5 and 0, respectively. All the patients who underwent epidural PCA had back pain at the puncture site and 1 patient who underwent modified intravenous analgesia injection experienced mild dyspnea, but they easily recovered with such

Between April 2004 and July 2004, 15 patients with symptomatic fibroids underwent uterine artery embolization and pain management. Except the three patients for whom the Visual Analogue Scale (VAS) score was not obtained, twelve patients were included in this study. For pain management, epidural PCA (Patient Controlled Analgesia) was used in two patients, intravenous PCA was used in two patients and modified intravenous analgesia injection was used in eight patients. For all the patients, we used the 2.8 Fr coaxial microcatheter and 500-710 μ m PVA particles for the embolic materials. The protocol of the modified intravenous analgesia injection was as follow, 1) prior to femoral artery puncture, 30 mg of ketorolac tromethamine (Tarasyn)was injected via an intravenous route. 2) At the time that the one side uterine artery embolization was finished, normal saline mixed 150 mg meperidine (Demerol) was administered through the side port of the intravenous line that was used for hydration. 3) Additional ketorolac tromethamine 30 mg was injected after 6 hour. The VAS score and side effects were then checked. After 12 hours, the VAS score was rechecked. If the VAS score was above 4, this was considered as failure of pain management. The VAS scores, complications and side effects for the modified intravenous analgesia injection were compared with that of IV PCA and epidural PCA. The average VAS score of the modified intravenous analgesia injection, intravenous PCA and epidural PCA was 1.4, 1 and 0, respectively; the number of additional intramuscular injections of analgesia was 0.5, 0.5 and 0, respectively. All the patients who underwent epidural PCA had back pain at the puncture site and 1 patient who underwent modified intravenous analgesia injection experienced mild dyspnea, but they easily recovered with such

    Background: Postoperative pain after breast cancer surgery is not uncommon. Narcotic based analgesia is commonly used for postoperative pain management. However, the side-effects and complications of systemic narcotics is a significant disadvantage. Different locoregional anesthetic techniques have been tried including, single and multiple levels paravertebral block (PVB), which seems to have a significant reduction in immediate postoperative pain with fewer side-effects. The aim of this study was to compare unilateral multiple level PVB versus morphine patient-controlled analgesia (PCA) for pain relief after breast cancer surgery with unilateral lumpectomy and axillary lymph nodes dissection. Materials and Methods: Forty patients scheduled for breast cancer surgery were randomized to receive either preoperative unilateral multiple injections PVB at five thoracic dermatomes (group P, 20 patients) or postoperative intravenous PCA with morphine (group M, 20 patients) for postoperative pain control. Numerical pain scale, mean arterial pressure, heart rate, Time to first analgesic demand, 24-h morphine consumption side-effects and length of hospital stay were recorded. Results: PVB resulted in a significantly more postoperative analgesia, maintained hemodynamic, more significant reduction in nausea and vomiting, and shorter hospital stay compared with PCA patients. Conclusion: Multiple levels PVB is an effective regional anesthetic technique for postoperative pain management, it provides superior analgesia with less narcotics consumption, and fewer side-effects compared with PCA morphine for patients with breast cancer who undergo unilateral lumpectomy, with axillary lymph nodes dissection.

    Somatosensory event-related potentials (SERPs) to painful electric standard stimuli under an odd-ball paradigm were analyzed in 12 high hypnotizable (HH), 12 medium hypnotizable (MH), and 12 low hypnotizable (LH) subjects during waking, hypnosis, and a cued eyes-open posthypnotic condition. In each of these conditions subjects were suggested to produce an obstructive imagery of stimulus perception as a treatment for pain reduction. A No-Analgesia treatment served as a control in waking and hypnosis conditions. The subjects were required to count the number of delivered target stimuli. HH subjects experienced significant pain and distress reductions during posthypnotic analgesia as compared to hypnotic analgesia and between these two analgesic conditions as compared to the two control conditions. Outside of hypnosis, these subjects remembered less pain and distress levels than they reported during hypnotic and posthypnotic analgesia treatments. In contrast, for waking-analgesia treatment, HH subjects remembered similar pain and distress levels to those they reported concurrently with the stimulation. HH subjects, during hypnotic and posthypnotic analgesia treatments, detected a smaller number of target stimuli and displayed a significant amplitude reduction of the midline frontal and central N140 and P200 SERP components. No significant SERP differences were observed for these subjects between treatments in waking condition and between hypnotic and posthypnotic analgesic treatments. For the MH and LH subjects no significant N140 and P200 amplitude changes were observed among analgesic conditions as compared to control conditions. These amplitude findings are seen as indicating that hypnotic analgesia can affect earlier and later stages of stimulus processing. PMID:18023535

    The provision of epidural analgesia for postoperative pain control offers many patient benefits and has become commonplace on many nursing units. Since nurses are responsible for the day-to-day management of patients receiving epidural analgesia, their knowledge, attitudes, and practices regarding this technique are pivotal to its success. Therefore, the purpose of the present descriptive study was to examine the knowledge base, attitudes, and clinical practice of registered nurses (N = 85) regarding postoperative epidural analgesia as managed by an acute pain service (APS). Information was obtained from a survey distributed via a convenience sample to all nurses working on 6 units in a large military teaching facility. We developed the "Epidural Knowledge and Attitude Survey" using the nursing literature on epidural analgesia. The survey consisted of a demographics section, true/false (T/F) questions, multiple choice (M/C) questions, an attitude section, and a comment section. These sections addressed the nurses' knowledge, attitudes, and practices in regard to epidural pharmacology, management, and adverse effects, as well as their general satisfaction with the APS of their facility. Data were analyzed statistically using means, standard deviations, percentages, forward step-wise linear regression, the Fisher-Irwin (exact) test, the chi 2 test, and analysis of variance with Bonferroni multiple comparisons. A P value of attitude section illustrated that 73% of nurses had "positive" attitudes toward epidural analgesia. Correct management of patients receiving epidural analgesia was being practiced by 77% of nurses. The satisfaction with the APS at this facility was 32% "very satisfied" and 62% "somewhat satisfied." The demographic characteristics that best predicted a higher score on the knowledge portion of the survey were greater years of practice as a nurse and receipt of pain education in nursing training. Nurses who had received inservice education about

    Full Text Available Purpose. Transversus abdominis plane (TAP blocks have been shown to reduce pain and opioid requirements after abdominal surgery. The aim of the present case series was to demonstrate the use of TAP catheter injections of bupivacaine after major abdominal surgery. Methods. Fifteen patients scheduled for open colonic resection surgery were included. After induction of anesthesia, bilateral TAP catheters were placed, and all patients received a bolus dose of 20 mL bupivacaine 2.5 mg/mL with epinephrine 5 μg/mL through each catheter. Additional bolus doses were injected bilaterally 12, 24, and 36 hrs after the first injections. Supplemental pain treatment consisted of paracetamol, ibuprofen, and gabapentin. Intravenous morphine was used as rescue analgesic. Postoperative pain was rated on a numeric rating scale (NRS, 0–10 at regular predefined intervals after surgery, and consumption of intravenous morphine was recorded. Results. The TAP catheters were placed without any technical difficulties. NRS scores were ≤3 at rest and ≤5 during cough at 4, 8, 12, 18, 24, and 36 hrs after surgery. Cumulative consumption of intravenous morphine was 28 (23–48 mg (median, IQR within the first 48 postoperative hours. Conclusion. TAP catheter bolus injections can be used to prolong analgesia after major abdominal surgery.

    AIM: To present our experience using intravenous sedoanalgesia for percutaneous biliary drainage. MATERIALS AND METHODS: This study comprised 100 patients, all of whom were continuously monitored [electrocardiogram (ECG), blood pressure, pulse oxymetry] and received an initial dose of 2 mg midazolam followed by 0.02 mg fentanyl. Before every anticipated painful procedure, a maintenance dose of 0.01 mg fentanyl was administered. If the procedure continued and the patient became aware, another 1 mg midazolam was given. This was repeated if patients felt pain. A total dose of 0.08 mg fentanyl and 7 mg midazolam was never exceeded. Immediately after the procedure, the nurse was asked to evaluate patients' pain score. The patients were asked 3 h later to complete a visual 10-degree pain score scale. RESULTS: The average dose of fentanyl and midazolam was 0.042 mg (0.03-0.08 mg) and 4.28 mg (2-7 mg), respectively. Only one patient recorded the procedure as painful. The scores given by the attending nurse (1-7 points, mean 2.9) correlated well with those given by the patients (1-6 points, mean 2.72). No complications were noted. CONCLUSION: According to our experience, interventional radiologists practising biliary procedures can administer low doses of midazolam and minimize the doses of fentanyl, without loss of adequate sedation and analgesia.

    An online survey utilizing Survey Monkey linked through the American Association of Zoo Veterinarians listserve examined current practices in megavertebrate analgesia. Data collected included drugs administered, dosing regimens, ease of administration, efficacy, and adverse events. Fifty-nine facilities (38 housing elephants, 33 housing rhinoceroses) responded. All facilities administered nonsteroidal anti-inflammatory drugs (NSAIDs), with phenylbutazone (0.25-10 mg/kg) and flunixin meglumine (0.2-4 mg/kg) being most common. Efficacy was reported as "good" to "excellent" for these medications. Opioids were administered to elephants (11 of 38) and rhinoceroses (7 of 33), with tramadol (0.5-3.0 mg/kg) and butorphanol (0.05-1.0 mg/kg) being most common. Tramadol efficacy scores were highly variable in both elephants and rhinoceroses. While drug choices were similar among institutions, substantial variability in dosing regimens and reported efficacy between and within facilities indicates the need for pharmacokinetic studies and standardized methods of analyzing response to treatment to establish dosing regimens and clinical trials to establish efficacy and safety.

    A double-blind, placebo-controlled, parallel-group study was performed to compare the analgesic activity of the combination of 650 mg acetaminophen plus 60 mg phenyltoloxamine citrate with that of 650 mg acetaminophen alone. Two hundred female inpatients who had severe pain associated with a recent episiotomy procedure were randomly assigned to receive a single dose of one of the two active treatments or a placebo. Analgesia was assessed over a 6-hour period. Treatments were compared on the basis of standard subjective scales for pain intensity and relief, a number of derived variables based on these data and two global measures. For essentially all measures, the two active treatments were significantly superior to the placebo control. The combination was significantly superior to acetaminophen alone for all analgesic measures including SPID, TOTAL, and global ratings. The results of this study demonstrate that 60 mg phenyltoloxamine produces significant augmentation of the analgesic activity of 650 mg acetaminophen in postepisiotomy pain. PMID:2569485

    Full Text Available Fundament: One of the most important aims of modern surgery is the recovery of the ill patients and heir integration to society. Sometimes, this wish has its limitations because of the persistence of pain after surgery. The development of an effective analgesic for after surgery pain is therefore a priority in modern medicine. Objective: To characterize the results obtained with the application of a preventive analgesic by infiltrating without limitations of the use of any other analgesic if necessary. Method: Prospective-descriptive study in a series of 30 patients assisted at the Orthopaedic Service of the ¨Dr. Gustavo Aldereguía Lima¨ Hospital from Cienfuegos province in the period that covers September 2004- march 2005. Anaesthetic infiltration in the surgical area was applied once the surgery was ended . Bupivacaine 0,125 % in a volume of 20 ml and 2 drops of epinephrine without avoiding the use of any other analgesic. Results: a group of 13 patients presented pain in the first 24-48 hours after surgery followed by another group of 9 patients who alleviated pain in the period between 12 and 23 hours after surgery. Conclusions: In this series of patients it was shown the benefits of anaesthetic infiltration in the surgical area with analgesic purposes, since it causes pain alleviation in a period greater than 24 hours. Bupivacaine shows good results since it causes after surgery analgesia and the early application in the rehabilitation of a great number of patients.

    Full Text Available In daily life, dental treatments are often related with oral pain sensation which needs anesthesia procedures. Sometimes local anesthetics can not be used because patients have hypersensitive reaction or systemic diseases which may lead to complications. Stimulating acupoint, such as Hegu activates hypothalamus and pituitary gland to release endogenous opioid peptide substances that reduce pain sensitivity. The aim of the study was to determine Hegu acupoint stimulation effect on the pain sensitivity reduction in maxillary central incisor gingiva. The laboratory experimental research was conducted on 12 healthy male Wistar rats (3 months old, weights 150–200 grams. All rat samples received the same treatments and adapted within 1 month. The research was done in pre and post test control group design. 40-Volt electro-stimulation was done once on the maxillary central incisor gingiva prior to the bilateral Hegu acupoint stimulation, then followed by 3 times electro-stimulation with 3 minutes intervals. The pain scores were obtained based on the samples’ contraction in each electro-stimulation. The responses were categorized into 5 pain scores and statistically analyzed using Wilcoxon Test. The results showed that Hegu acupoint stimulation lowered the pain scores significantly (p < 0.05. Hegu acupoint stimulation could reduce the pain sensitivity in maxillary central incisor gingiva. Therefore, the use of acupuncture analgesia in dental pain management can be considered in the future.

    The PhysioDoloris™ analgesia monitor assesses nociception effects on the autonomic nervous system by analyzing changes in heart rate variability (HRV). This non-invasive device analyses ECG signals and determines the analgesia nociception index (ANI), allowing for quantitative assessment of the analgesia/nociception balance in anesthetized patients. Ketamine, an analgesic adjuvant with sympathomimetic properties, has been shown to improve perioperative pain management. The purpose of this pilot study was to evaluate whether low-dose ketamine, due to its intrinsic effect on the sino-atrial node, affects HRV and, therefore, interferes with ANI measurements. This pilot study included 20 women undergoing abdominal hysterectomies. Anesthesia and analgesia were maintained with sevoflurane and fentanyl respectively, in a standardized manner. Five minutes after intubation, 0.5 μg kg(-1) of intravenous (i.v.) ketamine was administered. ANI, bispectral index (BIS), heart rate and blood pressure were recorded from the induction of anesthesia until 5 min after skin incision. There was not any significant decrease in mean (±SD) ANI values after intubation (2.11±20.11, p=0.35) or i.v. ketamine administration (1.31±15.26, p=0.28). The mean (±SD) reduction in ANI values after skin incision was statistically significant (13.65±15.44, p=0.01), which is consistent with increased nociception. A single i.v. bolus of 0.5 μg kg(-1) ketamine did not influence the ANI values of 20 women under standardized general anesthesia conditions and absent noxious stimulation. These results suggest that the ANI derived from the PhysioDoloris™ analgesia monitor is feasible under such clinical conditions. PMID:25062948

    The vast research have demonstrated that the acupuncture analgesia is effected through a physiological mechanism brought about by the nervous system, particularly the central nervous system. We combined the acupuncture effects and theory of channels and collaterals with the new advance of pain neurophysiology, and centred attention on nucleus raphe magnus (NRM), that is one of the origins of the important descending inhibitory pathways of the intrinsic analgesic systems in brain. The unit discharges of NRM neurons and their nociceptors/ph responses were recorded extracellularly with glass microelectrode at 1495 neurons on 634 wastar rats. The modulation of cerebral cortex, the head of N. caudatum (NCa), N. Accumbens (N. Ac), N lateral habenular (NHa) and Periaquaeductal gray matter (PAG) on NRM and their role in acupuncture analgesia were studied by central locational stimulation, lesion and microinjection. The result were as follows: 1. The most NRM neurons could respond to noxious stimulation of tail tip with increasing or decreasing firing rate. Electroacupuncture (EA) at "Zusanli" could activate the NRM neuron, increasing discharges, and inhibit their nociceptive responses, producing analgesia. 2. The activity of NRM neuron was modulated by PAG, NAc, and NCa. Stimulation at one of them can activate neuron of NRM, increasing firing rate, and induce analgesia. When the lesion or microinjection naloxone were made in PAG, NAc or NCa, EA analgesia could be weakened or lost, even the nociceptive responses might be increased. It is suggest that the nuclei participated in EA analgesia with their endogenous opiate like substance, and were playing an important role. It is also indicated that the electroacupuncture was used on the patients with some nuclei lesion or pathological changes should be careful to avoid making patients feel more painful. 3. Somatosensory area II (Sm II) of cerebral cortex participated in EA analgesia. The analgesic effects of EA at "Zusanli

    Full Text Available Remifentanil with appropriate pharmacological properties seems to be an ideal alternative to epidural analgesia during labour. A retrospective cohort study was undertaken to assess the efficacy and safety of remifentanil intravenous patient-controlled analgesia (IVPCA compared with epidural analgesia. Medical records of 370 primiparas who received remifentanil IVPCA or epidural analgesia were reviewed. Pain and sedation scores, overall satisfaction, the extent of pain control, maternal side effects and neonatal outcome as primary observational indicators were collected. There was a significant decline of pain scores in both groups. Pain reduction was greater in the epidural group throughout the whole study period (0 ∼ 180 min (P < 0.0001, and pain scores in the remifentanil group showed an increasing trend one hour later. The remifentanil group had a lower SpO2 (P < 0.0001 and a higher sedation score (P < 0.0001 within 30 min after treatment. The epidural group had a higher overall satisfaction score (3.8 ± 0.4 vs. 3.7 ± 0.6, P = 0.007 and pain relief score (2.9 ± 0.3 vs. 2.8 ± 0.4, P < 0.0001 compared with the remifentanil group. There was no significant difference on side effects between the two groups, except that a higher rate of dizziness (1% vs. 21.8%, P < 0.0001 was observed during remifentanil analgesia. And logistic regression analysis demonstrated that nausea, vomiting were associated with oxytocin usage and instrumental delivery, and dizziness was associated to the type and duration of analgesia. Neonatal outcomes such as Apgar scores and umbilical-cord blood gas analysis were within the normal range, but umbilical pH and base excess of neonatus in the remifentanil group were significantly lower. Remifentanil IVPCA provides poorer efficacy on labor analgesia than epidural analgesia, with more sedation on parturients and a trend of newborn acidosis. Despite these adverse effects, remifentanil IVPCA can still be an alternative

    Multimodal analgesia is promoted as the best practice pain management for invasive animal research procedures. Universal acceptance and incorporation of multimodal analgesia requires assessing potential effects on study outcome. The focus of this study was to assess effects on embryo survival after multimodal analgesia comprising an opioid and nonsteroidal antiinflammatory drug (NSAID) compared with opioid-only analgesia during embryo transfer procedures in transgenic mouse production. Mice were assigned to receive either carprofen (5 mg/kg) with buprenorphine (0.1 mg/kg; CB) or vehicle with buprenorphine (0.1 mg/kg; VB) in a prospective, double-blinded placebo controlled clinical trial. Data were analyzed in surgical sets of 1 to 3 female mice receiving embryos chimeric for a shared targeted embryonic stem-cell clone and host blastocyst cells. A total of 99 surgical sets were analyzed, comprising 199 Crl:CD1 female mice and their 996 offspring. Neither yield (pups weaned per embryo implanted in the surgical set) nor birth rate (average number of pups weaned per dam in the set) differed significantly between the CB and VB conditions. Multimodal opioid-NSAID analgesia appears to have no significant positive or negative effect on the success of producing novel lines of transgenic mice by blastocyst transfer. PMID:21838973

    Chromaffin cells synthesize and secrete several neuroactive substances, including catecholamines and opioid peptides, that, when injected into the spinal cord, induce analgesia. Moreover, the release of these substances from the cells can be stimulated by nicotine. Since chromaffin cells from one species have been shown to survive when transplanted to the central nervous system of another species, these cells are ideal candidates for transplantation to alter pain sensitivity. Bovine chromaffin cells were implanted into the subarachnoid space of the lumbar spinal region in adult rats. Pain sensitivity and response to nicotine stimulation was determined at various intervals following cell implantation. Low doses of nicotine were able to induce potent analgesia in implanted animals as early as one day following their introduction into the host spinal cord. This response could be elicited at least through the 4 months the animals were tested. The induction of analgesia by nicotine in implanted animals was dose related. This analgesia was blocked by the opiate antagonist naloxone and partially attenuated by the adrenergic antagonist phentolamine. These results suggest that the analgesia is due to the stimulated release of opioid peptides and catecholamines from the implanted bovine chromaffin cells and may provide a new therapeutic approach for the relief of pain.

    Full Text Available ABSTRACT BACKGROUND AND OBJECTIVES: Combined spinal-epidural (CSE has become an increasingly popular alternative to traditional labour epidural due to its rapid onset and reliable analgesia provided. This was a prospective, convenient sampling study to determine the effects of CSE analgesia on labour outcome. METHODS: One hundred and ten healthy primigravida parturients with a singleton pregnancy of ≥37 weeks gestation and in the active phase of labour were studied. They were enrolled to the CSE (n = 55 or Non-CSE (n = 55 group based on whether they consented to CSE analgesia. Non-CSE parturients were offered other methods of labour analgesia. The duration of the first and second stage of labour, rate of instrumental vaginal delivery and emergency cesarean section, and Apgar scores were compared. RESULTS: The mean duration of the first and second stage of labour was not significantly different between both groups. Instrumental delivery rates between the groups were not significantly different (CSE group, 11% versus Non-CSE group, 16%. The slightly higher incidence of cesarean section in the CSE group (16% versus 15% in the Non-CSE group was not statistically significant. Neonatal outcome in terms of Apgar score of less than 7 at 1 and 5 min was similar in both groups. CONCLUSION: There were no significant differences in the duration of labour, rate of instrumental vaginal delivery and emergency cesarean section, and neonatal outcome in parturients who received compared to those who did not receive CSE for labour analgesia.

    Full Text Available Ian Power, Jon G McCormackDepartment of Anaesthesia, Critical Care and Pain Medicine, The University of Edinburgh, Royal Infirmary, Edinburgh, UKAbstract: Effective pain relief is an essential component of a patient’s peri-operative care package. Good analgesia has been shown to reduce the incidence of cardiovascular, respiratory and thrombo-embolic complications following surgery. Satisfactory analgesia facilitates early patient ambulation following surgery, which may reduce in-patient stay. Patient-controlled analgesia (PCA systems are a well established standard therapy for acute post-operative pain; however some practical limitations limit their clinical utility. The fentanyl inotophoretic transdermal system (ITS is a novel self-contained needle-free PCA device, which delivers boluses of fentanyl transdermally. This system has been shown to provide analgesia equivalent to conventional PCA modalities, with unique design features that may confer advantages to patients and staff, including facilitating patient mobilization in the post-operative phase. This review will discuss the technology of iontophoretic systems, the pharmacology of transdermal fentanyl delivery, and some practical implications of the fentanyl ITS.Keywords: iontophoresis, transdermal, patient-controlled analgesia, fentanyl, post-operative pain

  15. Autoradiographic visualization on the role of central 3H-5-hydroxytryptamine in acupuncture analgesia

    International Nuclear Information System (INIS)

    The role played by central 5-hydroxytryptamine (5-HT) in electroacupuncture analgesia has been studied in rats by means of autoradiography with isotopic tracers 3H-5-HT. The purpose of the study is to determine the localization of 3H-5-HT in the midbrain raphe nuclei and in the mesencephalon aquaeduct as well as periaquaeductal gray matter. Parallel experiments were studied by freezing microautoradiographic method and histo-fixative microautoradiographic method. The analgesic effect of acupuncture can be enhanced or lowered by the increment or the decrement of the 5-HT level in the midbrain raphe nuclei and in the mesencephalon aquaeduct as well as periaquaeductal gray matter. The results show that when the rats were subjected to electro-acupuncture analgesia, the microautoradiographic intensities of 3H-5-HT both in the midbrain raphe nuclei and in the areas of mesencephalon aqueduct were significantly increased. It may be observed that the release of 5-HT in these regions of the brain is accelerated during acupuncture analgesia. From this it can be concluded that the midbrain raphe nuclei and the mesencephalon aquaeduct as well as the periaquaeductal gray matter are closely related to acupuncture analgesia. The results imply that 5-HT in these areas may be one of the most important neurochemical agents mediating acupuncture analgesia

    Full Text Available Background: Tapentadol is a relatively new analgesic. We decided to compare it with tramadol for their various effects after cardiac surgery. Setting: A study in a tertiary care hospital. Materials and Methods: Sixty adults undergoing cardiac surgery were divided into 2 groups of 30 each by computerized random allotment (Group X = tapentadol 50 mg oral and Group Y = tramadol 100 mg oral. Informed Consent and Institutional Ethics Committee approval were obtained. The patients were given either drug X or drug Y after extubation in this single blinded study, wherein the data collectors and analyzers were blinded to the study. All patients received oral paracetamol qds and either drug X or drug Y tds. The pain score was noted on a Visual Analog Scale before each drug dose, 3 h later and on coughing. Heart rate, respiratory rate, and blood pressure were recorded before the drug dose and 3 h later. Postoperative nausea or vomiting (PONV, temperature, and modified Glasgow Coma Scale readings were recorded. The above readings were obtained for 6 doses (up to 48 h after extubation. Statistics: t-test, Pearson Chi-square test, Fisher exact test, and Mantel-Haenszel test were used for statistics. Results: Tapentadol group patients had significantly better analgesia 3 h after the drug and "on coughing" than tramadol group. The difference in their effects on blood creatinine levels, temperature, hemodynamics, oxygen saturation, and respiratory rate were not clinically significant. Tapentadol produced lesser drowsiness and lesser vomiting than tramadol. Conclusions: Tapentadol, due to its norepinephrine reuptake inhibition properties, in addition to mu agonist, is a better analgesic than tramadol and has lesser PONV.

  19. Effects of regional analgesia on stress responses to pediatric surgery.

    Wolf, Andrew R

    2012-01-01

    Invasive surgery induces a combination of local response to tissue injury and generalized activation of systemic metabolic and hormonal pathways via afferent nerve pathways and the central nervous system. The local inflammatory responses and the parallel neurohumoral responses are not isolated but linked through complex signaling networks, some of which remain poorly understood. The magnitude of the response is broadly related to the site of injury (greater in regions with visceral pain afferents such as abdomen and thorax) and the extent of the trauma. The changes include alterations in metabolic, hormonal, inflammatory, and immune systems that can be collectively termed the stress response. Integral to the stress responses are the effects of nociceptive afferent stimuli on systemic and pulmonary vascular resistance, heart rate, and blood pressure, which are a combination of efferent autonomic response and catecholamine release via the adrenal medulla. Therefore, pain responses, cardiovascular responses, and stress responses need to be considered as different aspects of a combined bodily reaction to surgery and trauma. It is important at the outset to understand that not all components of the stress response are suppressed together and that this is important when discussing different analgesic modalities (i.e. opioids vs regional anesthesia). For example, in terms of the use of fentanyl in the infant, the dose required to provide analgesia (1-5 mcg·kg(-1)) is less than that required for hemodynamic stability in response to stimuli (5-10 mcg·kg(-1)) (1) and that this in turn is less than that required to suppress most aspects of the stress response (25-50 mcg·kg(-1)) (2). In contrast to this considerable dose dependency, central local anesthetic blocks allow blockade of the afferent and efferent sympathetic pathways at relatively low doses resulting in profound suppression of hemodynamic and stress responses to surgery.

    Full Text Available A function of the endogenous analgesic system is to prevent recuperative behaviors generated by tissue damage, thus preventing the emission of species-specific defensive behaviors. Activation of intrinsic nociception is fundamental for the maintenance of the behavioral strategy adopted. Tonic immobility (TI is an inborn defensive behavior characterized by a temporary state of profound and reversible motor inhibition elicited by some forms of physical restraint. We studied the effect of TI behavior on nociception produced by the formalin and hot-plate tests in guinea pigs. The induction of TI produced a significant decrease in the number of flinches (18 ± 6 and 2 ± 1 in phases 1 and 2 and lickings (6 ± 2 and 1 ± 1 in phases 1 and 2 in the formalin test when compared with control (75 ± 13 and 22 ± 6 flinches in phases 1 and 2; 28 ± 7 and 17 ± 7 lickings in phases 1 and 2. In the hot-plate test our results also showed antinociceptive effects of TI, with an increase in the index of analgesia 30 and 45 min after the induction of TI (0.67 ± 0.1 and 0.53 ± 0.13, respectively when compared with control (-0.10 ± 0.08 at 30 min and -0.09 ± 0.09 at 45 min. These effects were reversed by pretreatment with naloxone (1 mg/kg, ip, suggesting that the hypoalgesia observed after induction of TI behavior, as evaluated by the algesimetric formalin and hot-plate tests, is due to activation of endogenous analgesic mechanisms involving opioid synapses.

    Objective: to assess the analgesic efficacy of subcutaneous lidocaine and multimodal analgesia for chest tube removal following heart surgery. Methods: sixty volunteers were randomly allocated in two groups; 30 participants in the experimental group were given 1% subcutaneous lidocaine, and 30 controls were given a multimodal analgesia regime comprising systemic anti-inflammatory agents and opioids. The intensity and quality of pain and trait and state anxiety were assessed. The association between independent variables and final outcome was assessed by means of the Chi-squared test with Yates' correction and Fisher's exact test. Results: the groups did not exhibit significant difference with respect to the intensity of pain upon chest tube removal (p= 0.47). The most frequent descriptors of pain reported by the participants were pressing, sharp, pricking, burning and unbearable. Conclusion: the present study suggests that the analgesic effect of the subcutaneous administration of 1% lidocaine combined with multimodal analgesia is most efficacious. PMID:26625989

    Full Text Available We discuss the emerging translational tools for the study of acupuncture analgesia with a focus on psychophysical methods. The gap between animal mechanistic studies and human clinical trials of acupuncture analgesia calls for effective translational tools that bridge neurophysiological data with meaningful clinical outcomes. Temporal summation (TS and conditioned pain modulation (CPM are two promising tools yet to be widely utilized. These psychophysical measures capture the state of the ascending facilitation and the descending inhibition of nociceptive transmission, respectively. We review the basic concepts and current methodologies underlying these measures in clinical pain research, and illustrate their application to research on acupuncture analgesia. Finally, we highlight the strengths and limitations of these research methods and make recommendations on future directions. The appropriate addition of TS and CPM to our current research armamentarium will facilitate our efforts to elucidate the central analgesic mechanisms of acupuncture in clinical populations.

  6. The study of patient controlled analgesia undergoing interventional therapy for gynecology and obstetrics ailment

    International Nuclear Information System (INIS)

    Uterine artery embolism is widely used for interventional therapy of gynecology and obstetrics ailment, but immediate incidence of pain occurs in 90% to 100% after uterine artery embolism and postoperative incidence of pain takes place from 80% to 90%. Patient controlled epidural analgesia (PCEA) could be adopted to treat pain with obviously outweighed effects over the traditional drug regimen or patient intravenous analgesia during the period of interventional therapy of uterine artery embolization. PCEA possesses good effect of analgesia and less adverse reaction and furthermore could eliminate or lessen the sufferings of patient and thus improve rehabilitation quality. Adding droperidol (0.005%) into the preparation of PCEA could decrease adverse effect incidence of nausea and vomiting; so it deserves recommendation for extending application in clinical interventional therapy.

    Full Text Available BACKGROUND: This study aims to identify that intrathecal (i.t. injection of dexmedetomidine (Dex and ropivacaine (Ropi induces synergistic analgesia on chronic inflammatory pain and is accompanied with corresponding "neuron-astrocytic" alterations. METHODS: Male, adult Sprague-Dawley rats were randomly divided into sham, control and i.t. medication groups. The analgesia profiles of i.t. Dex, Ropi, and their combination detected by Hargreaves heat test were investigated on the subcutaneous (s.c. injection of complete Freund adjuvant (CFA induced chronic pain in rat and their synergistic analgesia was confirmed by using isobolographic analysis. During consecutive daily administration, pain behavior was daily recorded, and immunohistochemical staining was applied to investigate the number of Fos-immunoreactive (Fos-ir neurons on hour 2 and day 1, 3 and 7, and the expression of glial fibrillary acidic protein (GFAP within the spinal dorsal horn (SDH on day 1, 3, 5 and 7 after s.c. injection of CFA, respectively, and then Western blot to examine spinal GFAP and β-actin levels on day 3 and 7. RESULTS: i.t. Dex or Ropi displayed a short-term analgesia in a dose-dependent manner, and consecutive daily administrations of their combination showed synergistic analgesia and remarkably down-regulated neuronal and astrocytic activations indicated by decreases in the number of Fos-ir neurons and the GFAP expression within the SDH, respectively. CONCLUSION: i.t. co-delivery of Dex and Ropi shows synergistic analgesia on the chronic inflammatory pain, in which spinal "neuron-astrocytic activation" mechanism may play an important role.

    Lumbar spine surgery has a high incidence of postoperative pain, but this pain is treatable through many methods, including patient-controlled analgesia (PCA). Acupoint stimulation could be considered an adjunct to PCA, improving the effectiveness of analgesia for patients recovering from lumbar spine surgery. The current study aimed to examine the effect of acupoint stimulation with PCA on improving analgesia quality after lumbar spine surgery. A single-blinded, sham-controlled design was used for the experimental, not control, groups. Data collection for the control group was completed first, followed by data collection for the other 2 groups. Participants were randomly assigned to the acupoint stimulation (AS) (n = 45) or sham group (n = 45). All participants received structural PCA multimedia information before lumbar surgery. The AS group received auricular acupressure combined with transcutaneuos electric acupoint stimulation (TEAS) at the true acupoint; the sham group received acupoint stimulation in the same manner but at a sham acupoint and without embedding seeds; and the control group received no acupoint stimulations. The analgesia quality, analgesic consumption, and postoperative nausea and vomiting (PONV) were used as measure of effects for the interventions. Significant differences were found between the AS and control groups in pain intensity but not in the belief and satisfaction subscales of analgesia quality. Also found a significant difference among the 3 groups in analgesic consumption and the severity of PONV in the first 72 hours after surgery. The current study shows that the combination of auricular acupressure and TEAS reduced pain intensity, morphine consumption, and PONV severity. Acupoint stimulation could be considered a multimodal analgesia method and an adjunct to PCA for lumbar spine surgery patients. PMID:24144572

    Full Text Available Objective: Neostigmine can produce analgesia by acting on the spinal cord. This study was to determine the optimal single-dose of epidural neostigmine for postoperative analgesia after partial hepatectomy. Patients and Methods: Twenty-six patients undergoing elective partial hepatectomy under general anesthesia combined with epidural block were studied. The dose of epidural neostigmine was determined using Dixon′s up-and-down method, starting from neostigmine 100 μg with an interval of 25 μg. Thirty minutes after skin incision, a predetermined dose of neostigmine was injected via the epidural catheter. Each patient received 0.125% bupivacaine and fentanyl 2 μg/ml for patient controlled epidural analgesia (PCEA after the operation. Assessment of analgesia quality was performed at 8 h and 24 h after the operation. Results : The ED 50 of epidural neostigmine in combination with PCEA for satisfactory analgesia was 226.78 ± 33.20 μg. Probit analysis showed that the ED 50 and ED 95 of epidural neostigmine were 228.63 μg (95% CI = 197.95-299.77 μg and 300.12 μg (95% CI = 259.44-741.65 μg, respectively. Conclusion: The ED 50 and ED 95 of epidural neostigmine in combination with PCEA for satisfactory analgesia after partial hepatectomy were 228.63 μg (95% CI = 197.95-299.77 μg and 300.12 μg (95% CI = 259.44-741.65 μg.

    Background Although there are various methods for painless delivery such as using entonox gas, most of the people are unfamiliar or concerned about it yet. Objectives The purpose of this study was to assess maternal expectations and experience of labor analgesia with nitrous oxide. Patients and Methods In a clinical trial study, 98 pregnant women in active phase of delivery were studied randomly in two groups (intervention group = 49, control group = 49) after obtaining written consent. Efficacy, experience satisfaction, and also expectation of pregnant women about entonox gas in two groups were compared, likewise in intervention group before and after using entonox gas. Results Most of the pregnant women receiving entonox gas had less labor pain (91.8%), and were satisfied with it (98%). The severity of pain in the most of entonox user was moderate level (46.94%), while for the control group it was severe (55.10%) which was significant, 40.82% of the mother in entonox group had a severe pain and 10.20% had a very severe pain, whereas in the control group (55.10%) of the mother had a severe pain and 26.53% of the had very severe pain (P = 0.004). efficacy of labor pain was in moderate level in most cases. 49% of pregnant women receiving gas described their experience as a good and excellent. 80.9% indicated that they will request the mentioned painless method in the future. The amount of suffering from gas side effects was mild in most patients of intervention group (63%). Expectations of the majority of pregnant women in intervention group (before receiving gas) and control group for painless delivery were weak (65.3%, 40.9%). The percentage of positive expectations had increased after receiving entonox gas (P = 0.01). There was a difference between the expectations of intervention group receiving entonox gas and control group (P = 0.001). Positive expectations were more in intervention group than the control group. Most differences of expectations in intervention

    Background and Aims: Caudal epidural block is the most commonly used neuraxial block in children. Morphine has been used as a caudal additive for more than three decades. The aim of our study was to evaluate the efficacy and duration of analgesia of three different doses of caudal epidural morphine (CEM), and to find out the incidence of side effects. Material and Methods: This study was conducted on 75 patients of American Society of Anesthesiologists grades I and II, aged 2-12 years, undergoing lower abdominal and urogenital surgeries. Patients were randomly allocated to one of the three groups according to the dose of morphine. Group I received 30 μg/kg, group II 50 μg/kg, and group III 70 μg/kg. Heart rate, blood pressure, oxygen saturation, electrocardiogram, pain score, sedation score, duration of analgesia, and side-effects were noted. Results: The mean duration of analgesia was 8.63 h in group I, 13.36 h in group II and 19.19 h in group III. Respiratory depression was noted in three patients in group III. One patient in group I had itching. One patient each in groups I, II, and III had nausea/vomiting. Conclusion: CEM significantly prolongs the duration of analgesia, though with a higher dose the risk of respiratory depression should always be kept in mind. PMID:27275053

  20. Spinal cord distribution of 3H-morphine after intrathecal administration: Relationship to analgesia

    International Nuclear Information System (INIS)

    The distribution of intrathecally administered 3H-morphine was examined by light microscopic autoradiography in rat spinal cord and temporal changes in silver grain localization were compared with results obtained from simultaneous measurements of analgesia. After tissue processing, radio-activity was found to have penetrated in superficial as well as in deeper layers (Rexed lamina V, VII, and X) of rat spinal cord within minutes after application. Silver grain density reached maximal values at 30 min in every region of cord studied. Radioactivity decreased rapidly between 30 min and 2 hr and then more slowly over the next 24 hr. In rats tested for responses to a thermal stimulus (tail flick test), intrathecal administration of morphine (5 and 15 micrograms) resulted in significant dose dependent analgesia that peaked at 30 min and lasted up to 5 hr (P less than 0.5). There was a close relationship between analgesia and spinal cord silver grain density during the first 4 hr of the study. It is postulated that the onset of spinal morphine analgesia depends on appearance of molecules at sites of action followed by the activation of anti-nociceptive mechanisms

    Placebo analgesia involves the endogenous opioid system, as administration of the opioid antagonist naloxone decreases placebo analgesia. To investigate the opioidergic mechanisms that underlie placebo analgesia, we combined naloxone administration with functional magnetic resonance imaging. Naloxone reduced both behavioral and neural placebo effects as well as placebo-induced responses in pain-modulatory cortical structures, such as the rostral anterior cingulate cortex (rACC). In a brainstem-specific analysis, we observed a similar naloxone modulation of placebo-induced responses in key structures of the descending pain control system, including the hypothalamus, the periaqueductal gray (PAG), and the rostral ventromedial medulla (RVM). Most importantly, naloxone abolished placebo-induced coupling between rACC and PAG, which predicted both neural and behavioral placebo effects as well as activation of the RVM. These findings show that opioidergic signaling in pain-modulating areas and the projections to downstream effectors of the descending pain control system are crucially important for placebo analgesia.

    Placebo analgesia is one of the most striking examples of the cognitive modulation of pain perception and the underlying mechanisms are finally beginning to be understood. According to pharmacological studies, the endogenous opioid system is essential for placebo analgesia. Recent functional imaging data provides evidence that the rostral anterior cingulate cortex (rACC) represents a crucial cortical area for this type of endogenous pain control. We therefore hypothesized that placebo analgesia recruits other brain areas outside the rACC and that interactions of the rACC with these brain areas mediate opioid-dependent endogenous antinociception as part of a top-down mechanism. Nineteen healthy subjects received and rated painful laser stimuli to the dorsum of both hands, one of them treated with a fake analgesic cream (placebo). Painful stimulation was preceded by an auditory cue, indicating the side of the next laser stimulation. BOLD-responses to the painful laser-stimulation during the placebo and no-placebo condition were assessed using event-related fMRI. After having confirmed placebo related activity in the rACC, a connectivity analysis identified placebo dependent contributions of rACC activity with bilateral amygdalae and the periaqueductal gray (PAG). This finding supports the view that placebo analgesia depends on the enhanced functional connectivity of the rACC with subcortical brain structures that are crucial for conditioned learning and descending inhibition of nociception.

    Full Text Available Abstract Background and Objective Our objective was to report on the design and essentials of the Etoricoxib protocol- Preemptive and Postoperative Analgesia (EPPA Trial, investigating whether preemptive analgesia with cox-2 inhibitors is more efficacious than placebo in patients who receive either laparotomy or thoracotomy. Design and Methods The study is a 2 × 2 factorial armed, double blinded, bicentric, randomised placebo-controlled trial comparing (a etoricoxib and (b placebo in a pre- and postoperative setting. The total observation period is 6 months. According to a power analysis, 120 patients scheduled for abdominal or thoracic surgery will randomly be allocated to either the preemptive or the postoperative treatment group. These two groups are each divided into two arms. Preemptive group patients receive etoricoxib prior to surgery and either etoricoxib again or placebo postoperatively. Postoperative group patients receive placebo prior to surgery and either placebo again or etoricoxib after surgery (2 × 2 factorial study design. The Main Outcome Measure is the cumulative use of morphine within the first 48 hours after surgery (measured by patient controlled analgesia PCA. Secondary outcome parameters include a broad range of tests including sensoric perception and genetic polymorphisms. Discussion The results of this study will provide information on the analgesic effectiveness of etoricoxib in preemptive analgesia and will give hints on possible preventive effects of persistent pain.

    Full Text Available Background and Aims: A high percentage of patients undergoing arthroscopic repairs on day care basis complain of inadequate postoperative pain relief. Clonidine was evaluated for the best route as an adjuvant in regional anesthesia in anterior cruciate ligament (ACL repair to prolong analgesia. Material and Methods: A prospective randomized double-blinded study was planned in a tertiary care hospital in North India in which 85 American Society of Anesthesiologists I and II patients undergoing ACL repair were enrolled. All groups received 0.5% hyperbaric bupivacaine intrathecally as in control group C. Group IT received intrathecal 1 μg/kg of clonidine along with hyperbaric bupivacaine, group IA received 0.25% bupivacaine and 1 μg/kg clonidine intra-articularly, and group NB received 0.25% bupivacaine and 1 μg/kg clonidine in femoro-sciatic nerve block (FSNB. Postoperative pain free interval and block characteristics were the primary outcomes studied. Results: Pain-free duration was 546.90 (±93.66 min in group NB (P 0.001 in comparison to other groups. The mean rescue analgesic requirement and cumulative frequency of rescue analgesia were least in group NB, followed by groups IT, IA and C. Conclusion: Clonidine is safe and effective adjuvant with bupivacaine in prolonging analgesia through various routes employed for post knee surgery pain. The maximum prolongation of analgesia is achieved through FSNB with a risk of prolonging postanesthesia care unit stay.

    We suggest a new placebo analgesia animal model and investigated the role of the dopamine and opioid systems in placebo analgesia. Before and after the conditioning, we conducted a conditioned place preference (CPP) test to measure preferences for the cues (Rooms 1 and 2), and a hot plate test (HPT) to measure the pain responses to high level-pain after the cues. In addition, we quantified the expression of tyrosine hydroxylase (TH) in the ventral tegmental area (VTA) and c-Fos in the anterior cingulate cortex (ACC) as a response to reward learning and pain response. We found an enhanced preference for the low level-pain paired cue and enhanced TH expression in the VTA of the Placebo and Placebo + Naloxone groups. Haloperidol, a dopamine antagonist, blocked these effects in the Placebo + Haloperidol group. An increased pain threshold to high-heat pain and reduced c-Fos expression in the ACC were observed in the Placebo group only. Haloperidol blocked the place preference effect, and naloxone and haloperidol blocked the placebo analgesia. Cue preference is mediated by reward learning via the dopamine system, whereas the expression of placebo analgesia is mediated by the dopamine and opioid systems. PMID:26602173

    Full Text Available BACKGROUND: Good pain relief following caesarian section is of great importance and intrathecal opioids provide good quality postoperative analgesia for longer duration. So the following study describes a comparative study between intrathecal morphine and intrathecal buprenorphine for postoperative pain relief following caesarian section (CS under subarachnoid blockade. AIMS: The study was conducted to compare intrathecal morphine and buprenorphine for post of analgesia following CS, to achieve analgesia without seda tion for better maternal child bondage and to popularize intrathecal opioids . MATERIALS AND METHODS: 60 patients posted for CS under SAB were randomly allocated into group A and group B of 30 each, the group A received morphine 0.1 mg and buprenorphine 0 . 0 3 mg was given for group B patients along with the local anaesthetic. Subjective assessment of post - operative analgesia was done by direct questioning of the patient and by a five point pain scores. Duration of analgesia was taken as the time interval betw een the time of injection of intrathecal opiate and the time at which the patient felt pain and requested for additional analgesics. Data’s were analyzed using SPSS 16th version. OBSERVATION AND RESU LTS: The mean duration of post - operative analgesia with i ntrathecal morphine was 24.19+4 . 8 hours and that with buprenorphine was only 11.7+3.28 hours. Over weight patients reported a lower mean duration of analgesia. None of the patients in the study showed any bradycardia, hypotension, desaturation or respirato ry depression. Intrathecal opiates decreased the parenteral opiate requirements. The main side effects noticed were nausea in about 43% of patients in morphine group and 33% of patients in buprenorphine group. CONCLUSIONS: Intrathecal morphine 0 . 1 mg gives good post - operative analgesia of longer duration than buprenorphine 0 . 03mg. The quality of analgesia provided by intrathecal morphine was superior to

    We evaluated the influence of hypnotizability, pain expectation, placebo analgesia in waking and hypnosis on tonic pain relief. We also investigated how placebo analgesia affects somatic responses (eye blink) and N100 and P200 waves of event-related potentials (ERPs) elicited by auditory startle probes. Although expectation plays an important role in placebo and hypnotic analgesia, the neural mechanisms underlying these treatments are still poorly understood. We used the cold cup test (CCT) to induce tonic pain in 53 healthy women. Placebo analgesia was initially produced by manipulation, in which the intensity of pain induced by the CCT was surreptitiously reduced after the administration of a sham analgesic cream. Participants were then tested in waking and hypnosis under three treatments: (1) resting (Baseline); (2) CCT-alone (Pain); and (3) CCT plus placebo cream for pain relief (Placebo). For each painful treatment, we assessed pain and distress ratings, eye blink responses, N100 and P200 amplitudes. We used LORETA analysis of N100 and P200 waves, as elicited by auditory startle, to identify cortical regions sensitive to pain reduction through placebo and hypnotic analgesia. Higher pain expectation was associated with higher pain reductions. In highly hypnotizable participants placebo treatment produced significant reductions of pain and distress perception in both waking and hypnosis condition. P200 wave, during placebo analgesia, was larger in the frontal left hemisphere while placebo analgesia, during hypnosis, involved the activity of the left hemisphere including the occipital region. These findings demonstrate that hypnosis and placebo analgesia are different processes of top-down regulation. Pain reduction was associated with larger EMG startle amplitudes, N100 and P200 responses, and enhanced activity within the frontal, parietal, and anterior and posterior cingulate gyres. LORETA results showed that placebo analgesia modulated pain-responsive areas

    Full Text Available Abstract Background Whether epidural analgesia for labor prolongs the active-first and second labor stages and increases the risk of vacuum-assisted delivery is a controversial topic. Our study was conducted to answer the question: does lumbar epidural analgesia with lidocaine affect the progress of labor in our obstetric population? Method 395 healthy, nulliparous women, at term, presented in spontaneous labor with a singleton vertex presentation. These patients were randomized to receive analgesia either, epidural with bolus doses of 1% lidocaine or intravenous, with meperidine 25 to 50 mg when their cervix was dilated to 4 centimeters. The duration of the active-first and second stages of labor and the neonatal apgar scores were recorded, in each patient. The total number of vacuum-assisted and cesarean deliveries were also measured. Results 197 women were randomized to the epidural group. 198 women were randomized to the single-dose intravenous meperidine group. There was no statistical difference in rates of vacuum-assisted delivery rate. Cesarean deliveries, as a consequence of fetal bradycardia or dystocia, did not differ significantly between the groups. Differences in the duration of the active-first and the second stages of labor were not statistically significant. The number of newborns with 1-min and 5-min Apgar scores less than 7, did not differ significantly between both analgesia groups.

    Pain and diaphragmatic dysfunction are the major reasons for postoperative pulmonary complications after upper abdominal surgery. Preoperative administration of analgesics helps to reduce and prevent pain. The objective of this study was first to research the rate of pulmonary complications for laparoscopic cholecystectomy (LC) and then analyze the influence of preemptive analgesia on pulmonary functions and complications. Seventy patients scheduled for elective LC were included in our double-blind, randomized, placebo-controlled, prospective study. Randomly, 35 patients received 1 g etofenamate (group 1) and 35 patients 0.9% saline (group 2) intramuscularly 1 h before surgery. All patients underwent physical examination, chest radiography, lung function tests, and pulse oxygen saturation measurements 2 h before surgery and postoperatively on day 2. Atelectasis was graded as micro, focal, segmental, or lobar. With preemptive analgesia, the need for postoperative analgesia decreased significantly in group 1. In both groups mean spirometric values were reduced significantly after the operation, but the difference and proportional change according to preoperative recordings were found to be similar [29.5 vs. 31.3% reduction in forced vital capacity (FVC) and 32.9 vs. 33.5% reduction in forced expiratory volume in 1 s (FEV(1)) for groups 1 and 2, respectively]. There was an insignificant drop in oxygen saturation rates for both groups. The overall incidence of atelectasia was similar for group 1 and 2 (30.2 vs. 29.2%). Although the degree of atelectesia was found to be more severe in the placebo group, the difference was not statistically significant. We concluded that although preemptive analgesia decreased the need for postoperative analgesia, this had no effect on pulmonary functions and pulmonary complications. PMID:19117121

    Full Text Available Background: The aim of this retrospective study is to test the hypothesis that the use of spinal analgesia shortens the length of hospital stay after partial nephrectomy. Materials and Methods: We reviewed all patients undergoing partial nephrectomy for malignancy through flank incision between January 1, 2008, and June 30, 2011. We excluded patients who underwent tumor thrombectomy, used sustained-release opioids, or had general anesthesia supplemented by epidural analgesia. Patients were grouped into "spinal" (intrathecal opioid injection for postoperative analgesia versus "general anesthetic" group, and "early" discharge group (within 3 postoperative days versus "late" group. Association between demographics, patient physical status, anesthetic techniques, and surgical complexity and hospital stay were analyzed using multivariable logistic regression analysis. Results: Of 380 patients, 158 (41.6% were discharged "early" and 151 (39.7% were "spinal" cases. Both spinal and early discharge groups had better postoperative pain control and used less postoperative systemic opioids. Spinal analgesia was associated with early hospital discharge, odds ratio 1.52, (95% confidence interval 1.00-2.30, P = 0.05, but in adjusted analysis was no longer associated with early discharge, 1.16 (0.73-1.86, P = 0.52. Early discharge was associated with calendar year, with more recent years being associated with early discharge. Conclusion: Spinal analgesia combined with general anesthesia was associated with improved postoperative pain control during the 1 st postoperative day, but not with shorter hospital stay following partial nephrectomy. Therefore, unaccounted practice changes that occurred during more recent times affected hospital stay.

    According to our previous study, ellagic acid has both dose-related central and peripheral antinociceptive effect through the opioidergic and l-arginine-NO-cGMP-ATP sensitive K(+) channel pathways. In the present study, the systemic antinociceptive effects of ellagic acid in animal models of pain, and functional interactions between ellagic acid and morphine in terms of analgesia, tolerance and dependence were investigated. Ellagic acid (1-30mg/kg; i.p.) showed significant and dose-dependent antinociceptive effects in the acetic acid-induced writhing test. Intraperitoneal ellagic acid acutely interacted with morphine analgesia in a synergistic manner in this assay. Ellagic acid (1-10mg/kg; i.p.) also exerted analgesic activity in the hot-plate test. Pre-treatment with naloxone (1mg/kg; i.p.) significantly reversed ellagic acid, morphine as well as ellagic acid-morphine combination-induced antinociceptin in these two tests. More importantly, when co-administered with morphine, ellagic acid (1-10mg/kg) effectively blocked the development of tolerance to morphine analgesia in the hot-plate test. Likewise, ellagic acid dose-dependently prevented naloxone-precipitated withdrawal signs including jumping and weight loss. Ellagic acid treatment (1-30mg/kg; i.p.) had no significant effect on the locomotion activity of animals using open-field task. Therefore, these results showed that ellagic acid has notable systemic antinociceptive activity for both tonic and phasic pain models. Altogether, ellagic acid might be used in pain relief alone or in combination with opioid drugs because of enhancing morphine analgesia and preventing morphine-induced tolerance to analgesia and dependence.

    Full Text Available Objectives: A study to compare the efficacy between fentanyl and sufentanil combined with low concentration (0.0625% of bupivacaine for epidural labor analgesia in laboring women. Materials and Methods: Fifty full term parturients received an initial bolus dose of a 10 ml solution containing 0.125% bupivacaine. The patients were randomly divided into two: group F received 0.0625% bupivacaine with 2.5 mcg/ml fentanyl and group S received 0.0625% bupivacaine with 0.25 mcg/ml sufentanil. Verbal analogue pain scores, need of supplementary/rescue boluses dose of bupivacaine consumed, mode of delivery, maternal satisfaction, and neonatal Apgar scores were recorded. No significant difference was observed between both groups. Results: Both the groups provided equivalent labor analgesia and maternal satisfaction. The chances of cesarean delivery were also not increased in any group. No difference in the cephalad extent of sensory analgesia, motor block or neonatal Apgar score were observed. Although mean pain scores throughout the labor and delivery were similar in both groups, more patients in fentanyl group required supplementary boluses though not statistically significant. Conclusion: We conclude that both 0.0625% bupivacaine-fentanyl (2.5 μg/ml and 0.0625% bupivacaine-sufentanil (0.25 μg/ml were equally effective by continuous epidural infusion in providing labor analgesia with hemodynamic stability achieving equivalent maternal satisfaction without serious maternal or fetal side effects. We found that sufentanil was 10 times more potent than fentanyl as an analgesic for continuous epidural labor analgesia.

    Objective: Caudal epidural analgesia has become very common analgesic technique in paediatric surgery. Add-ing tramadol to bupivacaine for caudal injection prolongs duration of analgesia with minimal side effects. The aim of the study was to investigate the different effects of caudal bupivacaine versus bupivacaine with thamadol for postoperative analgesia in paediatric cancer patients. Methods: A prospective randomized controlled trial was conducted over 40 paediatric cancer pa-tients who were recruited from Children Cancer Hospital of Egypt (57357 Hospital). Patients were randomized into 2 groups: bupivacaine group (group B, 20 patients) to receive single shot caudal block of 1 mL/kg 0.1875% bupivacaine; tramadol group (group T, 20 patients) prepared as group B with the addition of 1 mg/kg caudal tramadol. Results: The mean duration of analgesia was significantly longer among group T than group B [(24 ± 13.7) hours versus (7 ± 3.7) hours respectively with P = 0.001]. Group T showed a significantly lower mean FLACC score than group B (2.2 ± 0.9 versus 3.6 ± 0.6 with P = 0.002). The difference in FLACC score was comparable on arrival, and after 2 and 4 hours. At 8 and 12 hours the group B recorded significantly higher scores (P = 0.002 and 0.0001 respectively). There were no significant differences between the groups as regards sedation score [the median in both groups was 1 (0–1) with P value = o.8]. No one developed facial flush or pruritis. Conclusion: Caudal injection of low dose tramadol 1 mg/kg with bupivacaine 0.1875% is proved to be effective, long standing technique for postoperative analgesia in major paediatric cancer surgery and almost devoid of side effect.

MÉTODO: Cien pacientes recibieron bloqueo del plexo lumbar a través del compartimiento del psoas y fueron comparados con 100 pacientes que recibieron bloqueo del plexo lumbar vía perivascular inguinal, identificados por el estimulador de nervios periféricos con la inyección de 40 mL bupivacaína a 0,25% sin epinefrina. La analgesia en los nervios ilioinguinal, genitofemoral, cutáneo femoral lateral, femoral y obturatorio fue evaluada a las 4, 8, 12, 16, 20 y 24 horas después del final de la intervención quirúrgica. La intensidad del dolor también fue medida en el mismo período. La cantidad de opioides administrada en el postoperatorio fue anotada. En cinco pacientes de cada grupo, un estudio radiográfico con contraste no iónico se realizó para medir la dispersión de la solución anestésica. RESULTADOS: Los nervios ilioinguinal, genitofemoral, cutáneo femoral lateral, femoral y obturatorio fueron bloqueados en 92% de los pacientes en el compartimiento del psoas versus 62% en el bloqueo perivascular inguinal. El bloqueo del plexo lumbar redujo la necesidad de opioides y 42% de los pacientes sometidos al bloqueo del compartimiento del psoas y 36% de los pacientes en el bloqueo inguinal no necesitaron analgésico adicional en el postoperatorio. La duración de la analgesia fue de aproximadamente 21 horas con el bloqueo del compartimiento del psoas y 15 horas en el bloqueo perivascular inguinal. CONCLUSIONES: El bloqueo del compartimiento del psoas y perivascular inguinal es una excelente técnica para la analgesia postoperatoria en intervenciones quirúrgicas ortopédicas reduciendo la necesidad de opioides.

    Ventilatory depression is a significant risk associated with the use of opioids. We assessed whether opioid-induced ventilatory depression can be selectively antagonized by an ampakine without reduction of analgesia. In 16 healthy men, after a single oral dose of 1,500 mg of the ampakine CX717, a target concentration of 100 ng/ml alfentanil decreased the respiratory frequency by only 2.9 +/- 33.4% as compared with 25.6 +/- 27.9% during placebo coadministration (P CX717 than with placebo. In contrast, CX717 did not affect alfentanil-induced analgesia in either electrical or heat-based experimental models of pain. Both ventilatory depression and analgesia were reversed with 1.6 mg of naloxone. These results support the use of ampakines as selective antidotes in humans to counter opioid-induced ventilatory depression without affecting opioid-mediated analgesia. PMID:19907420

The present study aims at comparing the hemodynamic, sedative, and analgesia potentiating effects of epidurally administered fentanyl and dexmedetomidine when combined with ropivacaine. Methods: A total of one hundred patients of both gender aged 21-56 years, American Society of Anaesthesiologist (ASA physical status I and II who underwent lower limb orthopedic surgery were enrolled into the present study. Patients were randomly divided into two groups: Ropivacaine + Dexmedetomidine (RD and Ropivacaine + Fentanyl (RF, comprising 50 patie nts each. Inj. Ropivacaine, 15 ml of 0.75%, was administered epidurally in both the groups with addition of 1 μg/kg of dexmedetomidine in RD group and 1 μg/kg of fentanyl in RF group. Besides cardio-respiratory parameters and sedation scores, various block characteristics were also observed which included time to onset of analgesia at T10, maximum sensory analgesic level, time to complete motor blockade, time to two segmental dermatomal regressions, and time to first rescue analgesic. At the end of study, data was compiled systematically and analyzed using ANOVA with post-hoc significance, Chi-square test and Fisher′s exact test. Value of P<0.05 is considered significant and P<0.001 as highly significant. Results: The demographic profile of patients was comparable in both the groups. Onset of sensory analgesia at T10 (7.12±2.44 vs 9.14±2.94 and establishment of complete motor blockade (18.16±4.52 vs 22.98±4.78 was significantly earlier in the RD group. Postoperative analgesia was prolonged significantly in the RD group (366.62±24.42 and consequently low dose consumption of local anaesthetic LA (76.82±14.28 vs 104.35±18.96 during epidural top-ups postoperatively.

To investigate the clinical efficacy of ultrasound and nerve stimulator guided continuous femoral nerve block analgesia after total knee arthroplasty. METHODS: 46 patients with ASA grade I-III who underwent total knee arthroplasty received postoperative analgesia from October 2012 to January 2013. In 22 patients, ultrasound and nerve stimulator guided continuous femoral nerve block were performed for analgesia (CFNB group; in 24 patients, epidural analgesia was done (PCEA group. The analgesic effects, side effects, articular recovery and complications were compared between two groups. RESULTS: At 6 h and 12 h after surgery, the knee pain score (VAS score during functional tests after active exercise and after passive excise in CFNB were significantly reduced when compared with PCEA group. The amount of parecoxib used in CFNB patients was significantly reduced when compared with PCEA group. At 48 h after surgery, the muscle strength grade in CFNB group was significantly higher, and the time to ambulatory activity was shorter than those in PCEA group. The incidence of nausea and vomiting in CFNB patients was significantly reduced when compared with PCEA group. CONCLUSION: Ultrasound and nerve stimulator guided continuous femoral nerve block provide better analgesia at 6 h and 12 h, demonstrated by RVAS and PVAS. The amount of parecoxib also reduces, the incidence of nausea and vomiting decreased, the influence on muscle strength is compromised and patients can perform ambulatory activity under this condition.

    Patterson, D R; Questad, K A; de Lateur, B J

    1989-01-01

    This paper presents a hypnotherapeutic intervention for controlling pain in severely burned patients while they go through dressing changes and wound debridement. The technique is based on Barber's (1977) Rapid Induction Analgesia (RIA) and involves hypnotizing patients in their rooms and having their nurses provide posthypnotic cues for analgesia during wound cleaning. Five subjects who underwent hypnotherapy showed reductions on their pain rating scores (Visual Analogue Scale) relative to their own baselines and to the pain curves of a historical control group (N = 8) matched for initial pain rating scores. Although the lack of randomized assignment to experimental and control groups limited the validity of the results, the findings provide encouraging preliminary evidence that RIA offers an efficient and effective method for controlling severe pain from burns.

  2. A Bayesian perspective on sensory and cognitive integration in pain perception and placebo analgesia.

    Directory of Open Access Journals (Sweden)

    Davide Anchisi

    Full Text Available The placebo effect is a component of any response to a treatment (effective or inert, but we still ignore why it exists. We propose that placebo analgesia is a facet of pain perception, others being the modulating effects of emotions, cognition and past experience, and we suggest that a computational understanding of pain may provide a unifying explanation of these phenomena. Here we show how Bayesian decision theory can account for such features and we describe a model of pain that we tested against experimental data. Our model not only agrees with placebo analgesia, but also predicts that learning can affect pain perception in other unexpected ways, which experimental evidence supports. Finally, the model can also reflect the strategies used by pain perception, showing that modulation by disparate factors is intrinsic to the pain process.

  3. Role of Esmolol in Perioperative Analgesia and Anesthesia: A Literature Review.

    2015-06-01

    Use of opioids to provide adequate perioperative analgesia often leads to respiratory depression, nausea, vomiting, urinary retention, pruritus, and opioid-induced hyperalgesia, with the potential to increase length of stay in the hospital. In an effort to reduce perioperative opioid administration yet provide appropriate pain relief, researchers began to study the use of esmolol beyond its well-known cardiovascular effects. Perioperative esmolol has been shown to reduce anesthetic requirements, decrease perioperative opioid use, decrease the incidence of postoperative nausea and vomiting, lead to an earlier discharge, and increase patient satisfaction. This article provides a review of the literature on the use of esmolol as an adjunct for perioperative analgesia and anesthesia. PMID:26137757

    Full Text Available Pre-hospital trauma treatment is an important situation in which pain should be appropriately assessed and treated, but there is a great lack of studies about it. Literature has widely pointed out that the underanalgesia problem is spread to all groups of patients. The objective of the study is to verify the efficacy of a sedation-analgesia protocol based on the use of NSAIDs, Fentanyl and Midazolam, for prehospital treatment of trauma patients. The protocol was tested in three Emergency Medical Services for a four month period, in which 30 patients were included in the study. Results evidenced a good management of both pain and anxiety in the majority of patients treated, with the achievement of analgesia target in 80% of the patients and sedation target in 100% of the patients.

    The approach to sedation, analgesia, and neuromuscular blockade during targeted temperature management (TTM) remains largely unstudied, forcing clinicians to adapt previous research from other patient environments. During TTM, very little data guide drug selection, doses, and specific therapeutic goals. Sedation should be deep enough to prevent awareness during neuromuscular blockade, but titration is complex as metabolism and clearance are delayed for almost all drugs during hypothermia. Deeper sedation is associated with prolonged intensive care unit (ICU) and ventilator therapy, increased delirium and infection, and delayed wakening which can confound early critical neurological assessments, potentially resulting in erroneous prognostication and inappropriate withdrawal of life support. We review the potential therapeutic goals for sedation, analgesia, and neuromuscular blockade during TTM; the adverse events associated with that treatment; data suggesting that TTM and organ dysfunction impair drug metabolism; and controversies and potential benefits of specific monitoring. We also highlight the areas needing better research to guide our therapy. PMID:26670815

    Chromaffin cells synthesize and secrete several neuroactive substances, including catecholamines and opioid peptides, that, when injected into the spinal cord, induce analgesia. Moreover, the release of these substances from the cells can be stimulated by nicotine. Since chromaffin cells from one species have been shown to survive when transplanted to the central nervous system of another species, these cells are ideal candidates for transplantation to alter pain sensitivity.

    Epidural analgesia (EA) was used in 29 patients undergoing surgical removal of lumbar discal hernia. Marcain EA with controlled medicinal sleep and non-assisted breathing allowed to perform the whole operation in 27 patients. EA may be ineffective in combination of sequestrated disk hernia with scarry adhesive process. The technique of the operation demands a single use of the anesthetic drug which is potent enough to make blockade throughout the operation up to the end. PMID:10738758

    2001-02-01

    We compared in a prospective, randomized, double-blinded study the analgesic efficacy of three drugs in 120 ASA I and II patients scheduled to undergo ambulatory hand surgery with IV regional anesthesia. At discharge, oral analgesic tablets were prescribed as follows: tramadol 100 mg every 6 h, metamizol 1 g every 6 h, and paracetamol (acetaminophen) 1 g every 6 h. Rescue medication consisted of oral dextropropoxyphene 100 mg on demand. Analgesic efficacy was evaluated by self-assessment of pain intensity by visual analog score at six different time intervals during the 48-h study period. Patients also recorded global pain relief on a 5-grade scale, total number of study and rescue analgesic tablets, frequency and severity of adverse effects, sleep pattern, and overall satisfaction. None of the study drugs alone provided effective analgesia in all patients. The percentage of patients who required supplementary analgesics was 23% with tramadol, 31% with metamizol, and 42% with acetaminophen. Tramadol was the most effective analgesic, as evidenced by low pain scores, least rescue medication, and fewest number of patients with sleep disturbance. However, the incidence of side effects was also increased with tramadol. Seven patients (17.5%) withdrew from the study because of the severity of nausea and dizziness associated with the use of tramadol. Metamizol and acetaminophen provided good analgesia in about 70% and 60% of patients, respectively, with a decreased incidence of side effects. Despite receiving oral analgesic medication, up to 40% of patients undergoing hand surgery experienced inadequate analgesia in this controlled trial. Although tramadol was more effective, its use was associated with the highest frequency and intensity of adverse effects and the most patient dissatisfaction. Metamizol and acetaminophen provided good analgesia with a small incidence of side effects. For patients undergoing ambulatory hand surgery, postoperative pain can last longer than

    Full Text Available Background and Aims: Low concentration local anaesthetic improves uteroplacental blood flow in antenatal period and during labour in preeclampsia. We compared neonatal outcome after epidural ropivacaine plus fentanyl with intramuscular tramadol analgesia during labour in high-risk parturients with intrauterine growth restriction of mixed aetiology. Methods: Forty-eight parturients with sonographic evidence of foetal weight <1.5 kg were enrolled in this non-randomized, double-blinded prospective study. The epidural (E group received 0.15% ropivacaine 10 ml with 30 μg fentanyl incremental bolus followed by 7–15 ml 0.1% ropivacaine with 2 μg/ml fentanyl in continuous infusion titrated until visual analogue scale was three. Tramadol (T group received intramuscular tramadol 1 mg/kg as bolus as well as maintenance 4–6 hourly. Neonatal outcomes were measured with cord blood base deficit, pH, ionised calcium, sugar and Apgar score after delivery. Maternal satisfaction was also assessed by four point subjective score. Results: Baseline maternal demographics and neonatal birth weight were comparable. Neonatal cord blood pH, base deficit, sugar, and ionised calcium levels were significantly improved in the epidural group in comparison to the tramadol group. Maternal satisfaction (P = 0.0001 regarding labour analgesia in epidural group was expressed as excellent by 48%, good by 52% whereas it was fair in 75% and poor in 25% in the tramadol group. Better haemodynamic and pain scores were reported in the epidural group. Conclusion: Epidural labour analgesia with low concentration local anaesthetic is associated with less neonatal cord blood acidaemia, better sugar and ionised calcium levels. The analgesic efficacy and maternal satisfaction are also better with epidural labour analgesia.

This study evaluated the effect of local anaesthesia and analgesia on vocal, physiological and behavioural responses during and after castration. A second purpose was to evaluate if herdsmen can effectively administer anaesthesia. Methods Four male piglets in each of 141 litters in five herds were randomly assigned to one of four treatments: castration without local anaesthesia or analgesia (C, controls, analgesia (M, meloxicam, local anaesthesia (L, lidocaine, or both local anaesthesia and analgesia (LM. Lidocaine (L, LM was injected at least three minutes before castration and meloxicam (M, LM was injected after castration. During castration, vocalisation was measured and resistance movements judged. Behaviour observations were carried out on the castration day and the following day. The day after castration, castration wounds were ranked, ear and skin temperature was measured, and blood samples were collected for analysis of acute phase protein Serum Amyloid A concentration (SAA. Piglets were weighed on the castration day and at three weeks of age. Sickness treatments and mortality were recorded until three weeks of age.

  3. Caudal block and emergence delirium in pediatric patients: Is it analgesia or sedation?

    Directory of Open Access Journals (Sweden)

    Aparna Sinha

    2012-01-01

    Full Text Available Background: Emergence delirium (ED although a short-lived and self-limiting phenomenon, makes a child prone to injury in the immediate postoperative period and hence is a cause of concern not only to the pediatric anesthesiologist, surgeons, and post anesthesia care unit staff but also amongst parents. Additional medication to quieten the child offsets the potential benefits of rapid emergence and delays recovery in day care settings. There is conflicting evidence of influence of analgesia and sedation following anesthesia on emergence agitation. We hypothesized that an anesthetic technique which improves analgesia and prolongs emergence time will reduce the incidence of ED. We selected ketamine as adjuvant to caudal block for this purpose. Methods: This randomized, double blind prospective study was performed in 150 premedicated children ASA I, II, aged 2 to 8 years who were randomly assigned to either group B (caudal with bupivacaine, BK (bupivacaine and ketamine, or NC (no caudal, soon after LMA placement. Recovery characteristics and complications were recorded. Results: Emergence time, duration of pain relief, and Pediatric Anesthesia Emergence Delirium (PAED scores were significantly higher in the NC group (P<0.05. Duration of analgesia and emergence time were significantly more in group BK than groups B and NC. However, the discharge readiness was comparable between all groups. No patient in BK group required to be given any medication to treat ED. Conclusion: Emergence time as well as duration of analgesia have significant influence on incidence of emergence delirium. Ketamine, as caudal adjuvant is a promising agent to protect against ED in children, following sevoflurane anesthesia.

    Background Early studies showed that naloxone infusion decreases the incidence of morphine-related side effects from intravenous patient-controlled analgesia. This study aimed to determine whether naloxone preserved analgesia while minimizing side effects caused by intravenous tramadol administration. Methods Eighty patients undergoing general anesthesia for cervical vertebrae surgery were randomly divided into four groups. All patients received 1 mg/kg tramadol 30 minutes before the end of surgery, followed by a continuous infusion with 0.3 mgkg-1·h-1 tramadol with no naloxone (group I, n=20), 0.05 μg-kg-1·h-1 naloxone (group II, n=20), 0.1 μg·kg-1·h-1 naloxone (group III, n=20) and 0.2 μg·kg-1·h-1 naloxone (group IV, n=20). Visual analog scales (VAS) for pain during rest and cough, nausea five-point scale (NFPS) for nausea and vomiting, and ramsay sedation score (RSS) for sedation were assessed at 2, 6,12, 24 and 48 hours postoperatively. Analgesia and side effects were evaluated by blinded observers. Results Seventy-eight patients were included in this study. The intravenous tramadol administration provided the satisfied analgesia. There was no significant difference in either resting or coughing VAS scores among naloxone groups and control group. Compared with control group, sedation was less in groups II, III, and IV at 6, 12, and 24 hours (P <0.05); nausea was less in groups II, III and IV than group I at 2, 6, 12, 24 and 48 hours postoperatively (P <0.05). The incidence of vomiting in the control group was 35% vs. 10% for the highest dose naloxone group (group IV) (P<0.01). Conclusion A small-dose naloxone infusion could reduce tramadol induced side effects without reversing its analgesic effects.

    2001-01-01

    Patient-controlled analgesia (PCA) is an analgesic technique originally used in adults but now with an established role in paediatric practice. It is well tolerated in children as young as 5 years and has uses in postoperative pain as well as burns, oncology and palliative care. The use of background infusions is more frequent in children and improves efficacy; however, it may increase the occurrence of adverse effects such as nausea and respiratory depression. Monitoring involves measurement of respiratory rate, level of sedation and oxygen saturation. Efficacy is assessed by self-reporting, visual analogue scales, faces pain scales and usage patterns. This is optimally performed both at rest and on movement. The selection of opioid used in PCA is perhaps less critical than the appropriate selection of parameters such as bolus dose, lockout and background infusion rate. Moreover, opioid choice may be based on adverse effect profile rather than efficacy. The concept of PCA continues to be developed in children, with patient-controlled epidural analgesia, subcutaneous PCA and intranasal PCA being recent extensions of the method. There may also be a role for patient-controlled sedation. PCA, when used with adequate monitoring, is a well tolerated technique with high patient and staff acceptance. It can now be regarded as a standard for the delivery of postoperative analgesia in children aged >5 years. PMID:11354699

METHOD: Data were collected from 928 patients who received PCEA in general surgical wards for postoperative analgesia using bupivacaine 0.125% with fentanyl 2 mug\\/mL. RESULTS: On the first postoperative day, the median visual analogue pain score was 2 at rest and 4 on activity. Hypotension occurred in 21 (2.2%) patients, excessive motor blockade in 16 (1.7%), high block in 5 (0.5%), nausea in 5 (0.5%) and pruritus in only 1 patient. Excessive sedation occurred in two (0.2%) patients but no intervention was required. There were no serious complications such as epidural abscess, infection or haematoma. CONCLUSION: Effective and safe postoperative analgesia can be provided with PCEA in a general surgical ward without recourse to high-dependency supervision.

    Full Text Available This study was performed to investigate the analgesic effect of lidocaine and a combination of lidocaine and ketamine following epidural administration in dromedary camels. Ten 12–18-month-old camels were randomly divided into two equal groups. In group L, the animals received 2% lidocaine (0.22 mg/kg and in group LK the animals received a mixture of 10% ketamine (1 mg/kg and 2% lidocaine (0.22 mg/kg administered into the first intercoccygeal (Co1–Co2 epidural space while standing. Onset time and duration of caudal analgesia, sedation level and ataxia were recorded after drug administration. Data were analysed by U Mann-Whitney tests and significance was taken as p < 0.05. The results showed that epidural lidocaine and co-administration of lidocaine and ketamine produced complete analgesia in the tail, anus and perineum. Epidural administration of the lidocaine-ketamine mixture resulted in mild to moderate sedation, whilst the animals that received epidural lidocaine alone were alert and nervous during the study. Ataxia was observed in all test subjects and was slightly more severe in camels that received the lidocaine-ketamine mixture. It was concluded that epidural administration of lidocaine plus ketamine resulted in longer caudal analgesia in standing conscious dromedary camels compared with the effect of administering lidocaine alone.

  10. Neuroimmune Interaction in the Regulation of Peripheral Opioid-Mediated Analgesia in Inflammation.

    Peripheral immune cell-mediated analgesia in inflammation is an important endogenous mechanism of pain control. Opioid receptors localized on peripheral sensory nerve terminals are activated by endogenous opioid peptides released from immune cells to produce significant analgesia. Following transendothelial migration of opioid-containing leukocytes into peripheral sites of inflammation, opioid peptides are released into a harsh milieu associated with an increase in temperature, low pH, and high proteolytic activity. Together, this microenvironment has been suggested to increase the activity of opioid peptide metabolism. Therefore, the proximity of immune cells and nerve fibers may be essential to produce adequate analgesic effects. Close associations between opioid-containing immune cells and peripheral nerve terminals have been observed. However, it is not yet determined whether these immune cells actually form synaptic-like contacts with peripheral sensory terminals and/or whether they secrete opioids in a paracrine manner. This review will provide novel insight into the peripheral mechanisms of immune-derived analgesia in inflammation, in particular, the importance of direct interactions between immune cells and the peripheral nervous system.

    Full Text Available Background: For lower abdomen and lower limb surgery, spinal anaesthesia is most common modality used in routine. This study was conducted on 50 ASA 1 and 2 planned for lower limb and lower abdomen surgery. Methods: 50 patients of ASA 1 and 2 scheduled for lower limb and lower abdominal surgery were selected. Each patient received 4 milliliter volume of 0.75% isobaric ropivacaine + 5 microgram dexmedetomidine. At the intervals of 1 minute, 2 minute, 5 minute, 10 minute, 20 minute, 30 minute and 1 hour, 2 hour and 3 hour reading of pulse rate and blood pressure were recorded. Postoperatively, pain scores were recorded by using Visual Analogue Scale. Results: There were no significant changes in systolic and diastolic blood pressure after induction. The combination of ropivacaine and dexmedetomidine provided better postoperative analgesia and reduced requirement of diclofenac injection in first 24 hour. Conclusions: The patients showed excellent hemodynamic stability and postoperative analgesia to ropivacaine + dexmedetomidine. Thus it is a safe modality for lower limb and lower abdomen surgery as far as haemodynamic effects and postoperative analgesia is concerned. [Int J Basic Clin Pharmacol 2013; 2(1.000: 26-29

    Full Text Available CONTEXT: Various adjuvants such as opioids or α2 agonists are being used to improve the quality and duration of caudal analgesia with local anesthetics. Dexmedetomidine a α2 agonist is used frequently in adult patients to enhance the local anesthetic effect. However there is little literature regarding its effectiveness in pediatric caudal analgesia. The objective of this study was to assess the efficacy of dexmedetomidine when used as an adjuvant to bupivacaine in increasing the duration of caudal analgesia. AIM: The aim of this study was to investigate the effect of adding Dexmedetomidine to caudal Bupivacaine and observe the effect on the duration of analgesia in the post-operative period. SETTINGS AND DESIGN: One year hospital based Double Blind Randomized Controlled Trial. METHODS AND MATERIAL: Sixty children, aged 1-6 years, undergoing lower abdominal surgeries were included in this prospective randomized double-blind study. The patients were randomly divided into two groups: Group I received Bupivacaine (0.25% 1ml/kg plus 1 ml of normal saline in the caudal epidural space. Group II was administered Bupivacaine (0.25% 1ml/ with Dexmedetomidine 2 mcg/ ml diluted to 1 ml of normal saline in the caudal epidural space. All anesthetic and surgical techniques were standardized. Heart rate, blood pressure, oxygen saturation, respiratory rate were monitored continuously. Surgery was started 10-15 minutes after the injection and confirming adequacy of caudal block. Duration of analgesia was assessed using FLACC scale (Face, Legs, Activity, Cry, Consolability scale. The time from administration of caudal anesthesia to the first time the FLACC score equal or greater than 4 was considered as the duration of caudal analgesia. Paracetamol suppository was used as rescue analgesia with a loading dose of 40mg/kg. STATISTICAL ANALYSIS: Mann-Whitney test and Student ‘t’test was used to compare the data obtained in the two groups. RESULTS: The

    Background Ropivacaine and levobupivacaine have been introduced into obstetric analgesic practice with the proposed advantages of causing less motor block and toxicity compared with bupivacaine. However, it is still controversial whether both anesthetics are associated with any clinical benefit relative to bupivacaine for labor analgesia. This study aimed to compare the analgesic efficacy, motor block and side effects of bupivacaine, ropivacaine and levobupivacaine at lower concentrations for patient-controlled epidural labor analgesia. Methods Four hundred and fifty nulliparous parturients were enrolled in this randomized clinical trial. A concentration of 0.05%, 0.075%, 0.1%, 0.125% or 0.15% of either bupivacaine (Group B), ropivacaine (Group R) or levobupivacaine (Group L) with sufentanil 0.5 μg/ml was epidurally administered by patient-controlled analgesia mode. Effective analgesia was defined as a visual analogue scale score was ≤30 mm. The relative median potency for each local anesthetic was calculated using a probit regression model. Parturients demographics, sensory and motor blockade, obstetric data, maternal side effects, hourly volumes of local anesthetic used, and others were also noted. Results There were no significant differences among groups in the numbers of effective analgesia, pain scores, hourly local anesthetic amount used, sensory and motor blockade, labor duration and mode of delivery, side effects and maternal satisfaction (P >0.05). The relative median potency was bupivacaine/ropivacaine: 0.828 (0.602-1.091), bupivacaine/levobupivacaine: 0.845 (0.617-1.12), ropivacaine/levobupivacaine: 1.021 (0.774-1.354), respectively. However, a significantly less number of effective analgesia and higher hourly local anesthetic use were observed in the concentration of 0.05% than those of ≥0.1% within each group (P<0.05). Conclusions Using patient-controlled epidural analgesia, lower concentrations of bupivacaine, ropivacaine and levobupivacaine

    In a previous study, we showed that electroacupuncture (EA) applied to the SI-6 point on the contralateral forelimb produces long-lasting and powerful analgesia in pain caused by ankle sprain in a rat model. To investigate the underlying mechanism of EA analgesia, the present study tested the effects of various antagonists on known endogenous analgesic systems in this model. Ankle sprain was induced in anesthetized rats by overextending their right ankle with repeated forceful plantar flexion and inversion of the foot. When rats developed pain behaviors (a reduction in weight-bearing of the affected hind limb), EA was applied to the SI-6 point on the contralateral forelimb for 30 min under halothane anesthesia. EA significantly improved the weight-bearing capacity of the affected hind limb for 2h, suggesting an analgesic effect. The alpha-adrenoceptor antagonist phentolamine (2mg/kg, i.p. or 30 microg, i.t.) completely blocked the EA-induced analgesia, whereas naloxone (1mg/kg, i.p.) failed to block the effect. These results suggest that EA-induced analgesia is mediated by alpha-adrenoceptor mechanisms. Further experiments showed that intrathecal administration of yohimbine, an alpha(2)-adrenergic antagonist, reduced the EA-induced analgesia in a dose-dependent manner, whereas terazosin, an alpha(1)-adrenergic antagonist, did not produce any effect. These data suggest that the analgesic effect of EA in ankle sprain pain is, at least in part, mediated by spinal alpha(2)-adrenoceptor mechanisms. PMID:17537577

    Full Text Available BACKGROUND: Addition of clonidine to ropivacaine (0.2% can potentially enhance analgesia without producing prolonged motor blockade. The aim of the study was to compare the post - operative pain relieving quality of ropivacaine (0.2% and clonidine mixture to that of p lain ropivacaine (0.2% following caudal block in children’s. OBJECTIVE: In this study I examined the quality, post - operative analgesia and haemodynamics effects in children when clonidine is added to ropivacaine for urogenital surgeries in caudal anaesthe sia. MATERIAL AND METHODS: In this clinical trial, 30 children’s aged 1 - 10 years who were candidates for elective urogenital surgeries were studied. Induction and maintenance of anaesthesia were achieved using propofol, sevoflurane and nitrous oxide. Child ren were randomly divided into 2 groups in double blind fashion, and were given caudal block with 0.2% ropivacaine (1ml/kg alone and ropivacaine plus clonidine 2mcg/kg. Haemodynamic parameters were observed before, during and after the surgical procedure. Post - operative analgesia evaluated using FLACC score and sedation was assessed using Ramsey sedation scale. Paracetamol was given orally for cases with FLACC score 4 or more. RESULTS: Duration of analgesia was found to be significantly longer in the group given ropivacaine plus clonidine. CONCLUSIONS: I concluded that addition of clonidine to ropivacaine prolongs the duration of post - operative analgesia without any respiratory or heamodynamic side - effects.

    Yong-Hai Sun

    Full Text Available Duloxetine, a serotonin and noradrenaline reuptake inhibitor, and celecoxib, a non-steroidal anti-inflammatory drug, are commonly used analgesics for persistent pain, however with moderate gastrointestinal side effects or analgesia tolerance. One promising analgesic strategy is to give a combined prescription, allowing the maximal or equal efficacy with fewer side effects. In the current study, the efficacy and side effects of combined administration of duloxetine and celecoxib were tested in the mouse formalin pain model. The subcutaneous (s.c. injection of formalin into the left hindpaw induced significant somatic and emotional pain evaluated by the biphasic spontaneous flinching of the injected hindpaw and interphase ultrasonic vocalizations (USVs during the 1 h after formalin injection, respectively. Pretreatment with intraperitoneal (i.p. injection of duloxetine or celecoxib at 1 h before formalin injection induced the dose-dependent inhibition on the second but not first phase pain responses. Combined administration of duloxetine and celecoxib showed significant analgesia for the second phase pain responses. Combination analgesia on the first phase was observed only with higher dose combination. A statistical difference between the theoretical and experimental ED50 for the second phase pain responses was observed, which indicated synergistic interaction of the two drugs. Concerning the emotional pain responses revealed with USVs, we assumed that the antinociceptive effects were almost completely derived from duloxetine, since celecoxib was ineffective when administered alone or reduced the dosage of duloxetine when given in combination. Based on the above findings, acute concomitant administration of duloxetine and celecoxib showed synergism on the somatic pain behavior but not emotional pain behaviors.

    Full Text Available Objective To observe the effect of forgetful analgesia induction and tracheal intubation on the hemodynamic changes in induction period in patients with obstructive jaundice, and explore a safe method for anesthesia induction and tracheal intubation. Methods Sixty patients with obstructive jaundice undergoing elective abdominal operation in General Hospital of PLA from February, 2013 to August, 2013 were involved in the present study. Participants included 36 male and 24 female patients, aging 19-65 years (mean 42±5 years, weighing 47-73 kg (mean 54±6 kg, with ASA Ⅰ-Ⅱ. These 60 patients were randomly divided into forgetful analgesia induction-tracheal intubation group (group A, n=30 and rapid induction-tracheal intubation group (group B, n=30. The heart rate (HR, mean arterial pressure (MAP, pulse oxygen saturation (SpO2 at the time point of before induction (T0, before intubation (T1, at the moment of intubation (T2 and 3 min after intubation (T3 were determined in both groups. Administration times of ephedrine hydrochloride and atropine was recorded in both groups. Results There was no significant difference in HR, MAP, SpO2 before and after induction in group A. In the patients of group B, the HR increased and MAP decreased after induction compared with those before induction (P<0.05, and the change of SpO2 was not significant. Ephedrine hydrochloride and atropine were administrated in both groups, and the cases and times of ephedrine hydrochloride administration were more in group B than in group A (P<0.05. Conclusion The forgetful analgesia induction-tracheal intubation could effectively control the stress response and reduce the fluctuation in hemodynamics during induction of anesthesia in patients with obstructive jaundice.

    Full Text Available Background and Aims: Caudal block (CB with adjuvants is routinely used in children for anaesthesia. We evaluated the efficacy of the α2 adrenergic agonist, dexmedetomidine at two different doses as an adjuvant to bupivacaine in CB. Methods: This study was conducted on ninety children. Control group BD0 received 0.25% bupivacaine 1 ml/kg, whereas, the study groups BD1 and BD2 received 1 μg/kg and 2 μg/kg dexmedetomidine, respectively, with 0.25% bupivacaine 1 ml/kg as a single shot CB. Adequacy of the block, haemodynamic changes, duration of analgesia and side effects were compared. Analysis of Variance was used for between-group comparisons of numerical variables. Student's t-test and Mann–Whitney U-test were used for quantitative data. Results: The demography was comparable. Anal sphincter 5 min after administration of the CB was relaxed in 89.3%, 82.1% and 75% of cases in BD0, BD1 and BD2 groups, respectively. The sphincter was relaxed at the end of surgery in all the cases. Comparable haemodynamics was noted with significantly prolonged duration of analgesia in the groups BD1 (964.2 ± 309 min and BD2 (1152.6 ± 380.4 min compared to control (444.6 ± 179.4 min. While no complications were encountered in groups BD0 and BD1, bradycardia was observed in four cases of BD2 group with accompanied hypotension in one of them. Conclusion: Dexmedetomidine as an adjuvant to bupivacaine improves the quality of CB, provides good operating conditions and increases the duration of post-operative analgesia. We conclude that 1 μg/kg is as effective as 2 μg/kg of dexmedetomidine and with a better safety profile.

    Full Text Available Introduction: Opioid receptors have been demonstrated in the peripheral nerve endings of afferent neurons. Blockade of these receptors with peripherally administered opioid is believed to result in analgesia. Aim: To evaluate whether buprenorphine added to bupivacaine for wound infiltration can enhance post-operative analgesia via peripheral mechanisms. Materials and Methods: Forty ASA I and II adult patients scheduled for open donor nephrectomy were enrolled in this randomized double blind prospective study. In group A ( n=20 patients, the wound was infiltrated with bupivacaine 0.5% (2 mg/kg and in group B ( n=20 with bupivacaine 0.5% (2 mg/kg and buprenorphine (2 μg/kg. All patients were given diclofenac 75 mg IM at 8 h interval. Post-operative quality of analgesia was assessed by VAS (0-10 for 24 h and when VAS > 4 rescue analgesic was administered. Total dose of rescue analgesic and side effects were noted. Results: The time of administration of first rescue analgesic was significantly higher in group B (10.52±5.54 h as compared to group A (3.275±1.8 h. Mean VAS was significantly lower in group B as compared to group A. The total dosage of rescue analgesic was more in group A as compared to group B patients. Conclusion: Addition of buprenorphine to the local anesthetic significantly prolonged the time to first rescue analgesic requirement and the total consumption of rescue analgesic in 24 h, thus providing evidence in support of the existence of peripheral opioid receptors.

    Full Text Available Rostral spread of intrathecal drugs and sensitization of supraspinal sites may provoke several adverse effects. This case describes a patient with right hemifacial paresthesia, trismus and dysphasia on the trigeminal nerve distribution after intrathecal sufentanil administration. Primigravida, 34 years, 39 weeks of pregnancy, with hypothyroidism and pregnancy induced hypertension. Allergic to latex. In the use of puran T4, 50 μg /day. When the patient presented cervical dilatation of 4 cm, she requested analgesia. She was placed in the sitting position and a spinal puncture was performed with a 27G needle pencil point in L4/L5 (1.5 mg of bupivacaine plus 7.5 μg of sufentanil. Next, was performed an epidural puncture in the same space. It was injected bupivacaine 0.065%, 10 ml, to facilitate the passage of the catheter. After 5 min lying down in the lateral upright position, she complained of perioral and right hemifacial paresthesia, mainly maxillary and periorbital, as well as trismus and difficulty to speak. The symptoms lasted for 30 min and resolved spontaneously. After 1 h, patient requested supplementary analgesia (12 ml of bupivacaine 0.125% and a healthy baby girl was born. Temporary mental alterations have been described with the use of fentanyl and sufentanil in combined epidural-spinal analgesia, such as aphasia, difficulty of swallowing, mental confusion and even unconsciousness. In this patient, facial areas with paresthesia indicated by patient appear in clear association with the ophthalmic and maxillary branches of the trigeminal nerve and the occurrence of trismus and dysphagia are in association with the mandibular motor branch. The exact mechanism of rostral spread is not known, but it is speculated that after spinal drug administration, a subsequent epidural dose may reduce the intratecal space and propel the drug into the supraspinal sites.

    Postsurgical oral self-administration of analgesics in rodents is an interesting technique of providing analgesia, avoiding the negative effects of manipulation. Several strategies, using gelatin or nutella, have already been described. However, rodents require some habituation period to reach a good intake because of their neophobic behavior. The current study aimed to explore whether buprenorphine when mixed with an extruded diet offers a potential treatment option in the pain management of mice using a triple approach: by measuring the spontaneous intake in healthy animals; by using the hot-plate test; and finally by assessing the drug's ability to provide postoperative analgesia in a surgical intervention of moderate severity (intra-utero electroporation). Mice consumed during 20 hours, similar amounts of extruded diet alone, mixed with glucosaline, and mixed with buprenorphine (0.03 mg per pellet) or meloxicam (0.25 mg per pellet) both of which were diluted in glucosaline, showing that no neophobia was associated with these administrations. Relative increase from baseline latency (% maximal possible effect) in the hot-plate test at 20 h of administration was significantly higher for oral buprenorphine in diet 0.03 mg/pellet, and diet 0.15 mg/pellet, compared with placebo and no differences were found between those oral administrations and subcutaneous buprenorphine 0.1 mg/kg measured 3 h later. The treatment was also effective in attenuating the reductions in food consumption and body weight that occur after surgery. These data suggest that providing buprenorphine with the diet is a feasible and effective way of self-administration of analgesia in mice and does not cause neophobia and may easily contribute to the refinement of surgical procedures.

    Full Text Available Background: Establishing an epidural in an agitated laboring woman can be challenging. The ideal pain control technique in such a situation should be effective, fast acting, and short lived. We assessed the efficacy of inhalational methoxyflurane (Penthrox™ analgesia as bridging analgesia for epidural placement. Materials and Methods: Sixty-four laboring women who requested epidural analgesia with pain score of ≥7 enrolled in an observational study, 56 of which completed the study. The parturients were instructed to use the device prior to the onset of uterine contraction pain and to stop at the peak of uterine contraction, repeatedly until epidural has been successfully placed. After each (methoxyflurane inhalation-uterine contraction cycle, pain, Richmond Agitation Sedation Scale (RASS, nausea and vomiting were evaluated. Maternal and fetal hemodynamics and parturient satisfaction were recorded. Results: The mean baseline pain score was 8.2 ± 1.5 which was reduced to 6.2 ± 2.0 after the first inhalation with a mean difference of 2.0 ± 1.1 (95% confidence interval 1.7-2.3, P < 0.0001, and continued to decrease significantly over the study period (P < 0.0001. The RASS scores continuously improved after each cycle (P < 0.0001. Only 1 parturient from the cohort became lightly sedated (RASS = −1. Two parturients vomited, and no significant changes in maternal hemodynamics or fetal heart rate changes were identified during treatment. 67% of the parturients reported very good or excellent satisfaction with treatment. Conclusion: Penthrox™ provides rapid, robust, and satisfactory therapy to control pain and restlessness during epidural placement in laboring parturient.

    (i) The structure and function of the meridian (chamd and collateral) described by ancient medical doctors may correspond to the blood circulation, nerve control and neurohumoral modulation of modern medicine. ( ii ) The needling, which can injure the tissue, is a noxious stimulation inducing pain. Acupuncture manipulation, such as lifting and thrusting, twisting and twirling, or electroacupuncturc (EA) with the sufferable biggest intensity for patients should be a stronger pain stimulation. The needling sensation of soreness, numbness, distension and heaviness is a deep pain.(iii) There is an intrinsic analgesic system in brain, which centers around the periventricular and periaqueductal grey matter, contains endorphins as possible mediators, goes through the descending inhibition system in medulla oblongata, and acts on the gating mechanism in spinal cord. It could be producing analgesia while the system is activated.(iv) NRM might be a supraspinal center modulating pain,and the R-S neurons could form a basic circuit of negative feedback modulating pain. The discovery of excitatory-inhibitory reversible R-S neurons may give a neurophysiological explanation for the double direction modulation of acupuncture at acupoint. (v) Non-noxious stimulation such as massage or stroking could excite type Ⅰ and Ⅱ afferent fibers, producing a weaker and transient analgesia through the spinal mechanism. When the acupoint is near the pain area, the afferent information from them could be converged on the same and neighboring spinal segments, the light acupuncture or low intensity of EA also has analgesic effects, showing acupoint specificity. But the acupoint specificity is not limited in a specialiy designated channel line, and it is closely related to the segment of innervation. (vi) While acupuncture manipulation of lifting and thrusting, twisting and twirling or a high intensity of EA is used, because the intensities of these stimulations exceed the threshold of afferent

In this prospective, randomized double-blind study, we determined the efficacy of TAP block in patients undergoing cesarean section. Materials and Methods: Totally, 62 parturients undergoing cesarean section were randomized in a double-blind manner to receive either bilateral TAP block at the end of surgery with 20 ml of 0.25% bupivacaine or no TAP block, in addition to standard analgesic comprising 75 mg diclofenac 8 hourly and intravenous patient-controlled analgesia (PCA tramadol. Each patient was assessed at 0, 4, 8, 12, 24, 36, and 48 h after surgery by an independent observer for pain at rest and on movement using numeric rating scale of 0-10, time of 1 st demand for tramadol, total consumption of PCA tramadol, satisfaction with pain management and side effects. Results: Use of tramadol was reduced in patients given TAP block by 50% compared to patients given no block during 48 h after surgery (P < 0.001. Pain scores were lower both on rest and activity at each time point for 24 h in study group (P < 0.001, time of first analgesia was significantly longer, satisfaction was higher, and side effects were less in study group compared to control group. Conclusion: Transverse abdominis plane block was effective in providing analgesia with a substantial reduction in tramadol use during 48 h after cesarean section when used as adjunctive to standard analgesia.

    Full Text Available Abstract Background Pharmacological activation of type-2 metabotropic glutamate receptors (mGlu2 receptors causes analgesia in experimental models of inflammatory and neuropathic pain. Presynaptic mGlu2 receptors are activated by the glutamate released from astrocytes by means of the cystine/glutamate antiporter (System xc- or Sxc-. We examined the analgesic activity of the Sxc- activator, N-acetyl-cysteine (NAC, in mice developing inflammatory or neuropathic pain. Results A single injection of NAC (100 mg/kg, i.p. reduced nocifensive behavior in the second phase of the formalin test. NAC-induced analgesia was abrogated by the Sxc- inhibitor, sulphasalazine (8 mg/kg, i.p. or by the mGlu2/3 receptor antagonist, LY341495 (1 mg/kg, i.p.. NAC still caused analgesia in mGlu3−/− mice, but was inactive in mGlu2−/− mice. In wild-type mice, NAC retained the analgesic activity in the formalin test when injected daily for 7 days, indicating the lack of tolerance. Both single and repeated injections of NAC also caused analgesia in the complete Freund’s adjuvant (CFA model of chronic inflammatory pain, and, again, analgesia was abolished by LY341495. Data obtained in mice developing neuropathic pain in response to chronic constriction injury (CCI of the sciatic nerve were divergent. In this model, a single injection of NAC caused analgesia that was reversed by LY341495, whereas repeated injections of NAC were ineffective. Thus, tolerance to NAC-induced analgesia developed in the CCI model, but not in models of inflammatory pain. The CFA and CCI models differed with respect to the expression levels of xCT (the catalytic subunit of Sxc- and activator of G-protein signaling type-3 (AGS3 in the dorsal portion of the lumbar spinal cord. CFA-treated mice showed no change in either protein, whereas CCI mice showed an ipislateral reduction in xCT levels and a bilateral increase in AGS3 levels in the spinal cord.

  9. Role of transcutaneous electrical nerve stimulation in post-operative analgesia

    Full Text Available The use of transcutaneous electrical nerve stimulation (TENS as non-pharmacological therapeutic modality is increasing. The types of TENS used clinically are conventional TENS, acupuncture TENS and intense TENS. Their working is believed to be based on gate control theory of pain and activation of endogenous opioids. TENS has been used in anaesthesia for treatment of post-operative analgesia, post-operative nausea vomiting and labour analgesia. Evidence to support analgesic efficacy of TENS is ambiguous. A systematic search of literature on PubMed and Cochrane Library from July 2012 to January 2014 identified a total of eight clinical trials investigating post-operative analgesic effects of TENS including a total of 442 patients. Most of the studies have demonstrated clinically significant reduction in pain intensity and supplemental analgesic requirement. However, these trials vary in TENS parameters used that is, duration, intensity, frequency of stimulation and location of electrodes. Further studies with adequate sample size and good methodological design are warranted to establish general recommendation for use of TENS for post-operative pain.

    Epidural blood flow was measured in seven patients undergoing elective abdominal surgery during combined lumbar epidural and general anesthesia. After an initial dose of 20 ml plain bupivacaine 0.5%, a continuous epidural infusion of bupivacaine 0.5% (8 ml/hr) was given for 16 hours for...... surgery, and 8, 12, and 16 hours later during the continuous infusion. Initial blood flow was 6.0 +/- 0.7 ml/min per 100 g tissue (mean +/- SEM). After epidural bupivacaine, blood flow increased in all seven patients to 7.4 +/- 0.7 ml (P less than 0.02). Initial level of sensory analgesia was T4.5 +/- 0...... than 0.03) in the other five patients as the level of sensory analgesia regressed postoperatively. These data suggest that changes in epidural blood flow during continuous epidural infusion of bupivacaine, and thus changes in rates of vascular absorption of bupivacaine from the epidural space, may be...

    This study was essentially an in vivo protection experiment designed to test further the hypothesis that stress induces release of endogenous opiods which then act at opioid receptors. Rats that were either subjected to restraint stress for 1 yr or unstressed were injected ICV with either saline or 2.5 ..mu..g of ..beta..-funaltrexamine (..beta..-FNA), an irreversible opioid antagonist that alkylates the mu-opioid receptor. Twenty-four hours later, subjects were tested unstressed for morphine analgesia or were sacrificed and opioid binding in brain was determined. (/sup 3/H)D-Ala/sup 2/NMePhe/sup 4/-Gly/sup 5/(ol)enkephalin (DAGO) served as a specific ligand for mu-opioid receptors, and (/sup 3/H)-bremazocine as a general ligand for all opioid receptors. Rats injected with saline while stressed were significantly less sensitive to the analgesic action of morphine 24 hr later than were their unstressed counterparts. ..beta..-FNA pretreatment attenuated morphine analgesia in an insurmountable manner. Animals pretreated with ..beta..-FNA while stressed were significantly more sensitive to the analgesic effect of morphine than were animals that received ..beta..-FNA while unstressed. ..beta..-FNA caused small and similar decreases in (/sup 3/H)-DAGO binding in brain of both stressed and unstressed animals. 35 references, 2 figures, 2 tables.

    Full Text Available Abstract Background Intensivists must provide enough analgesia and sedation to ensure dying patients receive good palliative care. However, if it is perceived that too much is given, they risk prosecution for committing euthanasia. The goal of this study is to develop consensus guidelines on analgesia and sedation in dying intensive care unit patients that help distinguish palliative care from euthanasia. Methods Using the Delphi technique, panelists rated levels of agreement with statements describing how analgesics and sedatives should be given to dying ICU patients and how palliative care should be distinguished from euthanasia. Participants were drawn from 3 panels: 1 Canadian Academic Adult Intensive Care Fellowship program directors and Intensive Care division chiefs (N = 9; 2 Deputy chief provincial coroners (N = 5; 3 Validation panel of Intensivists attending the Canadian Critical Care Trials Group meeting (N = 12. Results After three Delphi rounds, consensus was achieved on 16 statements encompassing the role of palliative care in the intensive care unit, the management of pain and suffering, current areas of controversy, and ways of improving palliative care in the ICU. Conclusion Consensus guidelines were developed to guide the administration of analgesics and sedatives to dying ICU patients and to help distinguish palliative care from euthanasia.

  13. The effect of etoricoxib premedication on postoperative analgesia requirement in orthopedic and trauma patients

    International Nuclear Information System (INIS)

    We have hypothesized that etoricoxib premedication would reduce the need for additional opioids following orthopedic trauma surgery. A double blind, controlled study, conducted in King Fahd University Hospital, King Faisal University, Dammam, Kingdom of Saudi Arabia. After obtaining the approval of Research and Ethics Committee and written consent, 200 American Society of Anesthesiology grade I and II patients that underwent elective upper limb or lower limb fracture fixation surgeries during the period from August 2005 to October 2007 were studied. Patients were randomly premedicated using 120 mg of etoricoxib or placebo n=100, each. To alleviate postoperative pain, a patient controlled analgesia device was programmed to deliver one mg of morphine intravenously locked lockout time, 6 minutes. Visual analog scale and total postoperative morphine consumption over 24 hours and the adverse effects were recorded. One hundred patients in each group completed the study period. Etoricoxib premedication provides a statistically significant postoperative morphine sparing effect over 24 hours postoperatively. Total morphine consumption was 44.2 (8.2) in the placebo and 35.17 mg in the etoricoxib groups p<0.001. The incidence of nausea and vomiting requiring treatment was lower in the etoricoxib group. p=0.014. The postoperative blood loss was similar in both groups. Etoricoxib is a suitable premedication before traumatic orthopedic surgery as it enhanced postoperative analgesia and reduced the need for morphine. (author)

    The aim of the present study was to investigate the effect of epidural analgesia combined with general anesthesia on hemodynamics. Thirty patients undergoing surgery for the treatment of cancer of the neck were studied. The patients were divided into two groups of those who received epidural analgesia combined with general anesthesia group (Group 1) and those with general anesthesia alone (Group 2). Blood pressure was not different between the groups. But heart rate and rate pressure products in Group 1 were significantly lower than those of Group 2. CVP in Group 1 increased significantly to 10.1 +/- 2.9 mmHg during surgery from 6.8 +/- 1.8 mmHg at the beginning of the surgery. There was no difference in intraoperative blood loss and the amount of fluid infused between the two groups. These results suggest that epidural anesthesia combined with general anesthesia is effective to stabilize hemodynamics during cervical surgery, but we have to be careful about using local anesthetics during long cervical procedures, because it increases CVP which might result from the depression of cardiac function.

    Nowadays, there is compelling evidence that there is a poor relationship between the incoming sensory input and the resulting pain sensation. Signals coming from the peripheral nervous system undergo a complex modulation by cognitive, affective, and motivational processes when they enter the central nervous system. Placebo- and hypnosis-induced analgesia form two extreme examples of how cognitive processes may influence the pain sensation. With the advent of modern brain imaging techniques, researchers have started to disentangle the brain mechanisms involved in these forms of cognitive modulation of pain. These studies have shown that the prefrontal and anterior cingulate cortices form important structures in a descending pathway that modulates incoming sensory input, likely via activation of the endogenous pain modulatory structures in the midbrain periaqueductal gray. Although little is known about the receptor systems involved in hypnosis-induced analgesia, studies of the placebo response suggest that the opiodergic and dopaminergic systems play an important role in the mediation of the placebo response.

    Objective. To compare the analgesic efficacy and adverse effects of patient-controlled analgesia (PCA) with tramadol and with morphine for postoperative middle or severe pain. Methods. Fifty-nine patients, scheduled for elective hysterectomy or hysteromyomectomy, were ran domly divided into Group T (tramadol-treated group) and Group M (morphine-treated group). The 2 drugs were administered intravenously via a patient-controlled analgesia device till 24 h postoperatively. Efficacy was assessed by comparing total pain relief (TOTPAR) and the sum of pain intensity difference (SPID) values over 24 h. Results. Statistically significant equivalence of tramadol and morphine was shown by TOTPAR values (15.9+4.4 and 16.4+3.5, respectively) and SPID values (9.2+4.7 and 9.0±2.0, respectively) (P>0.05). Tramadol caused fewer adverse events than morphine(16.7% and 26.7% of patients, respectively). Conclusion. The analgesic efficacy of PCA with tramadol and with morphine were equivalent in the treatment of postoperative pain, and tramadol can cause slighter gastrointestinal adverse effects.

  17. Comparison of caudal bupivacaine and bupivacaine-tramadol for postoperative analgesia in children with hypospadias repair

    International Nuclear Information System (INIS)

    To compare the effects after caudal bupivacaine alone and bupivacaine-tramadol in young children with hypospadias repair. Randomized controlled trial. Sixty children aged between 13-53 months coming for hypospadias repair were divided randomly into two groups A and B. A caudal block was performed immediately after induction of general anaesthesia. The patients in group A received 0.125% bupivacaine 1 ml/kg with tramadol 1 mg/kg body weight caudally. Group B patients received 0.25% bupivacaine 1 ml/kg body weight caudally. Anaesthesia was discontinued after completion of surgery. In the recovery area, ventilatory frequency and pain scores were recorded at 1 hourly interval for first 6 hours and then every 2 hours for next 6 hours postoperatively. A modified TPPPS (Toddler-Preschool Postoperative Pain Scale) was used to assess the pain. Episodes of vomiting, facial flush and pruritus were noted, if present. The duration of analgesia was significantly prolonged in group A patients (p-value=0.001). A low frequency of postoperative vomiting was observed in both groups i.e. 10% in group A and 6.66% in group B (p-value=0.64). No respiratory depression, flushing and pruritus were observed. Low dose combination of bupivacaine and tramadol, when administered caudally, had an additive effect and provided prolonged and effective postoperative analgesia with minimal side effects. The risk of toxicity from bupivacaine decreased when combined with tramadol in low doses. (author)

    Pain behavior and awareness are characterized by heightened alertness and anxiety, which begin to disappear as soon as the curative process starts. The present study aimed to quantify c-fos expression in rat spinal cords and brains after a surgical stimulus and with preoperative or postoperative acupuncture. Animals were randomly divided into preoperative and postoperative groups and were then further divided into control, manual acupuncture (MA), or electroacupuncture (EA) groups. Expression of c-fos was quantified using immunohistochemistry. The collected data were analyzed using the t test at a 5% probability level. Presurgery and postsurgery spinal cord c-fos expressions were similar in all of the treatment groups. In the control rats, c-fos expression was higher before surgery than after surgery, contradicting the expected outcome of acupuncture and preemptive analgesia. After treatment, the expression of c-fos in the brains of the rats in the MA and the EA groups was reduced compared with that of the rats in the control group. These findings suggest that acupuncture used as preemptive analgesia in rats is a useful model for studying its application in human treatment. PMID:26896072

    We conducted a prospective study to assess how well parents ensured that their children received their prescribed analgesia following tonsillectomy. Our study was based on 69 cases of tonsillectomy that were carried out at our tertiary pediatric care center. Postoperatively, all patients were prescribed paracetamol (acetaminophen) on the basis of their weight; the standard pediatric dosage of this agent at the time of our study was 60 mg\\/kg\\/day. The parents were telephoned 2 weeks postoperatively to assess their compliance with this regimen. Of the original 69 patients who had been recruited, 66 completed the study-35 girls and 31 boys, aged 2 to 15 years (mean: 7.0; median 5.5). According to the parents, only 15 children (22.7%) received our recommended 60-mg\\/kg\\/day dosage and were thus determined to be fully compliant. Overall, parents reported a wide variation in the amount of drug administered, ranging from 12.5 to 111.0 mg\\/kg\\/day (mean: 44.8), indicating that parents often underdose their children. We recommend that more emphasis be placed on weight-directed, parent-provided analgesia during the post-tonsillectomy period.

  20. Functional MRI studies of acupuncture analgesia modulating within the human brain

    Objective: To evaluate the correlation between acupuncture analgesia and specific functional areas of the brain using functional magnetic resonance imaging (fMRI). Methods: Acupuncture stimulation was induced by manipulating acupuncture needle at the acupuncture point, large intestine 4 (LI 4, Hegu) on the right (dominant) hand of 8 healthy subjects. Functional MRI data were obtained from scanning the whole brain. A block-design paradigm was applied. Functional responses were established by students' group t-test analysis. Results: The data sets from 6 of 8 subjects were used in the study. Signal increases and signal decreases elicited by acupuncture stimulating were demonstrated in multiple brain regions. Signal increases in periaqueductal gray matter and ventral posterior nucleus of the left thalamus, and signal decreases in bilateral anterior cingulate cortex and bilateral occipital lobes were considered as the response to the acupuncture modulating within the human brain. Conclusion: The therapeutic effect of acupuncture analgesia was probably produced by the interaction of multiple brain structures of functional connectivity rather than through the activation of a single brain region

    Casi la generalidad de los estudios realizados sobre cementos con adición de cenizas volantes se refieren a sus características y comportamiento en pastas, morteros y hormigones, siempre en relación con aquéllos del cemento portland. Esta vez, se desarrolló un trabajo experimental orientado a relacionar entre sí los cementos con adiciones de cenizas volantes y de puzolana natural. Para ello se fabricaron a escala de laboratorio cementos de ambos tipos, empleando como materias primas comunes clinker y yeso y, como variables, diferentes porcentajes de las dos adiciones, que cumplieron previamente los requisitos normalizados en cuanto a sus actividades puzolánicas. La calidad de los cementos fabricados resultó adecuada y concordante con la del cemento portland-puzolánico obtenido a escala industrial con los mismos clinker, yeso y puzolana natural de este estudio. Posteriormente, se determinaron las características de los cementos experimentales y se confeccionaron morteros normales para la realización de ensayos físicos y mecánicos. Los resultados de ensayos indicaron que los cementos con adición de cenizas volantes (CCV requieren menos agua para consistencia normal, presentan tiempos de fraguado mayores y expansiones en autoclave menores que los cementos con adición de puzolana (CP.

    Full Text Available BACKGROUND AND OBJECTIVE: We compared the efficacy of intravenous (IV paracetamol versus dipyrone via patient-controlled analgesia (PCA for postoperative pain relief in children. METHODS: The study was composed of 120 children who had undergone elective tonsillectomy after receiving general anesthesia. Patients were divided into 3 groups according to the dosage of postoperative intravenous-patient-controlled analgesia: paracetamol, dipyrone, or placebo. Pain was evaluated using a 0- to 100-mm visual analog scale and 1- to 4-pain relief score at 30 min, 1, 2, 4, 6, 12, and 24 h postoperatively. Pethidine (0.25 mg kg-1 was administered intravenously to patients requiring rescue analgesia. Pethidine requirements were recorded during the first 24 h postoperatively, and treatment related adverse effects were noted. RESULTS: Postoperative visual analog scale scores were significantly lower with paracetamol group compared with placebo group at 6 h (p 0.05. Postoperative pethidine requirements were significantly lower with paracetamol and dipyrone groups compared with placebo group (62.5%, 68.4% vs 90%, p 0.05. CONCLUSIONS: Paracetamol and dipyrone have well tolerability profile and effective analgesic properties when administered IV-PCA for postoperative analgesia in children after tonsillectomy.

    To understand the mechanisms those are involved in the appearance of foetal heart rate decelerations (FHR) after the combined epidural analgesia in labour. Observational study done at University Hospital for 86-term singleton pregnant women with spontaneous labour. Serial bedside measurement of the main cardiac maternal parameters with USCOM technique; stroke volume (SV), heart rate (HR), cardiac output (CO) and total vascular resistances (TVR) inputting systolic and diastolic blood pressure before combined epidural analgesia and after 5', 10', 15' and 20 min. FHR was continuously recorded though cardiotocography before and after the procedure. Correlation between the appearance of foetal heart rate decelerations and the modification of maternal haemodynamic parameters. Fourteen out of 86 foetuses showed decelerations after the combined spino epidural procedure. No decelerations occurred in the women with low TVR (1200 dyne/s/cm(-5)). Soon after the epidural procedure, the absence of increase in SV and CO was observed in these women. No variations in systolic and diastolic blood pressure values were found. The level of TVR before combined epidural analgesia in labour may indicate the risk of FHR abnormalities after the procedure. Low TVR (<1000 dyne/s/cm(-5)) showed a reduced risk of FHR abnormalities. FHR decelerations seem to occur in women without the ability to upregulate SV and CO in response to the initial effects of analgesia. PMID:26333691

    This study was conducted to identify the opioid receptor subtype(s) responsible for RFR-induced analgesia. Male Swiss Webster mice, 20-25 g, were exposed to 20 mW/cm{sup 2} RFR in a 2,450-MHz waveguide system for 10 min, then tested 15 min later in the abdominal constriction paradigm which detects {mu}- and {kappa}-opioid activity. Immediately following RFR exposure, different groups of mice were pretreated intracerebroventricularly with different opioid receptor blockers with selectivity for {mu}- or {kappa}-opioid receptors. Results show that RFR-induced analgesia was attenuated by higher but not lower doses of the non-selective antagonist naloxone, but the selective {mu}-opioid antagonist {beta}-funaltrexamine and by the selective {kappa}-opioid antagonist norbinaltorphimine. RFR-induced analgesia was also reduced by subcutaneous pretreatment with 5.0 mg/kg of the {mu}-/{kappa}-opioid antagonist({minus})-5,9-diethyl-{alpha}-5,9-dialkyl-2{prime}-hydroxy-6,7-benzomorphan(MR-2266). These findings suggest that RFR-induced analgesia may be mediated by both {mu}- and {kappa}-opioid mechanisms.

If already in 1889 Giuseppe Sergi wanted that the artificial selection take it to end what should make the natural, avoiding the risk of the so called «degeneration», only in the face of the First World War seems to grow the alarm for the decadent quality of the population, finding a more and more wide echo.

    Full Text Available Multimodal analgesia refers to the practice of combining multiple analgesic drug classes or techniques to target different points along the pain pathway. The objective of this work was to evaluate clinically if ketoprofen associated or not with intravenous or epidural morphine provided adequate postoperative analgesia in bitches undergoing ovariosalpingohysterectomy (OSH. Forty healthy female dogs, weighing 10.7±6.0 kg, sedated with acepromazine (0.05mg kg –1.iv, induced with propofol (5 mg.kg-1. iv and maintained with isoflurane anesthesia, were distributed into four groups of 10 animals each. After stabilization of inhalation anesthesia, the bitches in Miv and CMiv groups received 0.2 mg.kg-1 of morphine intravenously diluted in 10ml of saline; whereas Mep and CMep groups received 0.1mg.kg-1 of epidural morphine. Thirty minutes after premedication, 2.0mg.kg-1.im of ketoprofen was administered in groups CMiv and CMep. Heart and respiratory rate, systolic blood pressure, and rectal temperature were measured. The degree of analgesia was assessed by a blind study in the following 6 hours after surgery, using a descriptive scale and a scale composed by physiologic and behavioral parameters. An statistical analysis was performed using the Tukey-Kramer test and nonparametric Kruskal-Wallis test, with statistical significance of 5%. There was no important difference between the four groups regarding postoperative analgesia, heart and respiratory rate, systolic blood pressure and rectal temperature. According to the results it can be concluded that the use of ketoprofen associated with intravenous or epidural morphine provided adequate and safe analgesia in the first six hours of postoperative in bitches undergoing ovariohysterectomy, suggesting that there was no analgesic potentiation when both agents were combined.

    The effect of chronic and acute oral or intraperitoneal treatment with the antidepressant drugs, desipramine, amitriptyline, alaproclate and iprindole, upon pain thresholds in the tail flick, hot plate and shock titration tests of nociception in saline- and 5-MeODMT-treated rats was studied. Chronic desipramine treatment increased the pre-test tail flick latencies. In the saline-treated rats, chronic oral desipramine treatment increased tail flick latencies, whereas chronic oral amitriptyline treatment decreased tail flick latencies. In 5-MeODMT-treated rats, chronic oral desipramine treatment attenuated the effects of 5-MeODMT (1 mg/kg) in all three tests of nociception, whereas chronic amitriptyline caused a potentiation in the tail flick and hot plate tests. Chronic oral iprindole treatment attenuated 5-MeODMT-induced analgesia in the hot plate test. Chronic intraperitoneal desipramine treatment attenuated 5-MeODMT analgesia in the tail flick and shock titration tests. In a different chronic treatment experiment, oral desipramine treatment attenuated 5-MeODMT analgesia in the tail flick test and zimeldine did for both the tail flick and hot plate tests, whereas mianserin potentiated 5-MeODMT-induced analgesia in both the tail flick and hot plate tests. In the saline-treated rats, acute treatment with all four drugs, desipramine, amitriptyline, iprindole and alaproclate, elevated the shock thresholds, whereas in 5-MeODMT-treated rats, desipramine and amitriptyline elevated shock thresholds. Two main conclusions can be drawn: chronic desipramine caused a quite consistent attenuation of 5-MeODMT-induced analgesia and the effects of acute treatment differed strongly from that of the chronic treatment. The effects of chronic administration with these antidepressants were compared with other findings using different measures of behavioural and receptor function. PMID:3776549

    Full Text Available Background and Aims: Efforts to prolong analgesia with various intrathecal and oral adjuvants have been tried with varying success. The present study was aimed to explore and to compare the potential beneficial effects of prolongation of spinal analgesia with two different doses of oral clonidine. Materials and Methods: A randomized double-blind study was carried out among 60 (American Society of Anesthesiologists-I and II patients with aged range from 25 to 65 years undergoing lower abdominal surgery. They were divided randomly into three groups of 20 each. Group 1 patients were administered placebo whereas Group 2 and 3 received oral clonidine tablets (0.15 and 0.30 mg respectively 1-h prior to surgery. Subarachnoid block was administered as per standard protocol. Time to onset of analgesia at T-10, time to achieve maximum sensory level, dermatomal regression and time to rescue analgesia were observed. Side-effects such as hypotension, bradycardia, nausea and vomiting were noted. Statistical analysis was performed using ANOVA with post-hoc Students unpaired t-test and Chi-square test and value of P 0.05. Two segment regression was 78.3 ± 10.44 min, 150.2 ± 23.07 min and 149.3 ± 18.33 min in Groups 1-3 respectively. Time to rescue analgesia was significantly prolonged in Groups 2 and 3 compared with Group 1 (P < 0.05. Incidence of hypotension was higher in Group 2 (P < 0.05. Conclusion: Optimal dose of oral clonidine that produces clinically useful prolongation of spinal anesthesia using bupivacaine appears to be 0.15 mg when compared with 0.3 mg when overall efficacy is being compared.

    Full Text Available Objective: Our primary objective in this study is to compare the effects of the applications of desflurane and remifentanyl anaesthesia, along with lumbar epidural analgesia combined with desflurane on postoperative recovery in the cases who undergoing lower abdominal surgery. Methods: This study performed 240 patients who undergoing elective lower abdominal surgery. Patients were divided into two random groups as Group DR (desflurane + remifentanyl n=120 and Group DL (desflurane +Lumbar Epidural Analgesia n=120.The general anaesthesia in Group DR was performed through the use of desflurane and remifentanyl. Group DL was administered a general anaesthesia through a pre-operative epidural catheter insertion and an application of desflurane. Extubation, eye opening, head lift for 5 seconds, and the surgical durations of the patients as well as the postoperative side-effects were recorded. Modified Aldrete Scoring System was used to assess the recovery of the patients from anaesthesia. Results: According to the inter group comparison results between Group DR and Group DL, the duration of extubation, eye opening, head lift for 5 seconds and the average amount of elapsed time until the modified Aldrete Scoring reached 10 were found statistically and significantly shorter in Group DL than Group DR( respectively p=0.002, p<0.001, p<0.001, p<0.001.The duration of the first analgesic need was statistically and significantly longer in Group DL compared to Group DR (p<0.001. The postoperative patient satisfaction in Group DL was statistically and significantly higher than that in Group DR (p=0.010. Conclusion: The Epidural analgesia included in the general anaesthesia in lower abdominal surgery is considered by us to be the beneficial and efficient method of analgesia which leads to an earlier recovery of the patients without affecting the intraoperative hemodynamic stability and which boosts the patient satisfaction by providing a more efficient analgesia

Morphine and hydromorphone remain the most commonly used opioids for PCA. Although both are effective, adverse effects may occur. When these adverse effects are unremitting or severe, opioid rotation may be required. In this study, we retrospectively evaluated PCA use, the adverse effect profile, and the frequency of opioid rotation. Methods: This retrospective study was performed at Nationwide Children’s Hospital (Columbus, OH. The hospital's electronic registry was queried for PCA use delivering either morphine or hydromorphone from January 1, 2008 to December 31, 2010. Results: A total of 514 patients were identified, that met study entry criteria. Of the 514 cases, 298 (56.2% were initially started on morphine and 225 (43.8% were initially started on hydromorphone. There were a total of 26 (5.1% opioid changes in the cohort of 514 patients. Of the 26 switches, 23 of 298 (7.7% were from morphine to hydromorphone, and 3 of 225 (1.3% were from hydromorphone to morphine (P=0.0008. Of the 17 morphine-to-hydromorphone switches with adverse effects, pruritus (64.7%, and inadequate pain control (47.1% were the most common side effects. The most common side effect resulting in a hydromorphone-to-morphine switch was nausea (66.7%. Conclusion: PCA switches from morphine-to-hydromorphone (88.5% were more common than vice-versa (11.5%. The most common reasons for morphine-to-hydromorphone switch were pruritus and inadequate pain control. These data suggest that a prospective study is necessary

    Factor V Leiden mutation is the most common congenital thrombophilic disorder, affecting between 5% and 8% of the Caucasian population. Pregnancy creates a state of hypercoagulability and all factors that increase the risk of thrombosis should be considered, as they may be cumulative. In recent years, the diagnosis of new allelic variants of thrombophilic states have increased the incidence of pregnant women receiving anticoagulant therapy, with the anesthetic considerations that implies. We report the case of a 33-year-old woman with heterozygous Leiden factor V mutation who was admitted with spontaneous amniorrhexis in the 38th week of gestation. She was taking low molecular weight heparin therapy. An epidural catheter was inserted to provide analgesia for labor, with all safety precautions to prevent an epidural hematoma. Epidural anesthesia is the technique of choice for obstetric labor in patients with hypercoagulability because of its effects of favoring blood flow and inhibiting clot formation. PMID:17319433

    1998-07-01

    Full Text Available The management of pain in patients with burn wounds is complex and problematic. Burn-wound pain is severe, inconsistent and underestimated. Patients experience severe pain, especially during procedures, until wound healing has occurred. A multi-modality approach is needed for effective management of pain, which requires an understanding of the mechanisms of pain. Altered pharmacokinetics and pharmacodynamics in burn-wound patients makes drug actions unpredictable. Opioids alone are seldom sufficient for pain control. The multi-modality approach includes the use of opioids and non-steroidal antiinflammatory, anxiolytic and alternative drugs. Ketamine has been found to be a useful agent for analgesia in burn-wound patients; a dose of 10 mg/kg qid per os was found to be an effective adjunct to pain therapy.

    In teaching centers, primary failure of thoracic epidural analgesia can be due to multiple etiologies. In addition to the difficult anatomy of the thoracic spine, the conventional end point-loss-of-resistance-lacks specificity. Furthermore, insufficient training compounds the problem: learning curves are nonexistent, pedagogical requirements are often inadequate, supervisors may be inexperienced, and exposure during residency is decreasing. Any viable solution needs to be multifaceted. Learning curves should be explored to determine the minimal number of blocks required for proficiency. The problem of decreasing caseload can be tackled with epidural simulators to supplement in vivo learning. From a technical standpoint, fluoroscopy and ultrasonography could be used to navigate the complex anatomy of the thoracic spine. Finally, correct identification of the thoracic epidural space should be confirmed with objective, real-time modalities such as neurostimulation and waveform analysis. PMID:27035462

    Relief of acute pain after hip and knee replacement represents a major therapeutic challenge as post-operative pain hinders early mobilisation and rehabilitation with subsequent consequences on mobility, duration of hospitalisation and overall recovery. In recent years, there has been increased...... interest in high-volume local wound infiltration/infusion techniques in these operations with a combined administration of local anaesthetics, NSAIDs and epinephrine. This review provides an update of the current knowledge of the efficacy of the high-volume wound infiltration technique based on randomised...... either intraoperatively or with a post-operative wound infusion catheter technique, provided that multimodal, oral non-opioid analgesia is given. In knee replacement, the data support the intraoperative use of the local infiltration technique but not the post-operative use of wound catheter...

    This proof of principle study examined the potential benefits of EEG neurofeedback for increasing responsiveness to self-hypnosis training for chronic pain management. The study comprised 20 individuals with multiple sclerosis (MS) who received 5 sessions of self-hypnosis training--1 face-to-face session and 4 prerecorded sessions. Participants were randomly assigned to have the prerecorded sessions preceded by either (a) EEG biofeedback (neurofeedback) training to increase left anterior theta power (NF-HYP) or (b) a relaxation control condition (RLX-HYP). Eighteen participants completed all treatment sessions and assessments. NF-HYP participants reported greater reductions in pain than RLX-HYP participants. The findings provide support for the potential treatment-enhancing effects of neurofeedback on hypnotic analgesia and also suggest that effective hypnosis treatment can be provided very efficiently.

    Postoperative nausea and vomiting (PONV) are major problems after gynaecological surgery. We studied 40 patients undergoing total abdominal hysterectomy, allocated randomly to receive opioid-free epidural-spinal anaesthesia or general anaesthesia with continuous epidural bupivacaine 15 mg h-1 or...... continuous bupivacaine 10 mg h-1 with epidural morphine 0.2 mg h-1, respectively, for postoperative analgesia. Nausea, vomiting, pain and bowel function were scored on 4-point scales for 3 days. Patients undergoing general anaesthesia had significantly higher nausea and vomiting scores (P < 0.01) but...... significantly lower pain scores during rest (P < 0.05) and mobilization (P < 0.01). More patients undergoing general anaesthesia received antiemetics (13 vs five; P < 0.05), but fewer received supplementary opioids on the ward (eight vs 16; P < 0.05). We conclude that opioid-free epidural-spinal anaesthesia for...

The groups were compared in terms of the times to perform the procedures, analgesia, parent satisfaction and orthopedic team.Results:13 patients were allocated to ketamine and 12 to morphine, without differences in relation to age, weight, gender, type of injury, and pain scale before the intervention. There was no failure in any of the groups, no differences in time to start the intervention and overall procedure time. The average hospital stay time was similar (ketamine = 10.8+5.1h versus morphine = 12.3+4.4hs; p=0.447. The median pain (faces pain scale scores after the procedure was 2 in both groups. Amnesia was noted in 92.3% (ketamine and 83.3% (morphine (p=0.904. Parents said they were very satisfied in relation to the analgesic intervention (84.6% in the ketamine group and 66.6% in the morphine group; p=0.296. The satisfaction of the orthopedist regarding the intervention was 92.3% in the ketamine group and 75% in the morphine group (p=0.222.Conclusion:by producing results similar to morphine, ketamine can be considered as an excellent option in pain management and helps in the reduction of dislocations and closed fractures in pediatric emergency rooms.

  1. US-Guided Femoral and Sciatic Nerve Blocks for Analgesia During Endovenous Laser Ablation

    International Nuclear Information System (INIS)

    Endovenous laser ablation may be associated with significant pain when performed under standard local tumescent anesthesia. The purpose of this study was to investigate the efficacy of femoral and sciatic nerve blocks for analgesia during endovenous ablation in patients with lower extremity venous insufficiency. During a 28-month period, ultrasound-guided femoral or sciatic nerve blocks were performed to provide analgesia during endovenous laser ablation in 506 legs and 307 patients. The femoral block (n = 402) was performed at the level of the inguinal ligament, and the sciatic block at the posterior midthigh (n = 124), by injecting a diluted lidocaine solution under ultrasound guidance. After the blocks, endovenous laser ablations and other treatments (phlebectomy or foam sclerotherapy) were performed in the standard fashion. After the procedures, a visual analogue pain scale (1–10) was used for pain assessment. After the blocks, pain scores were 0 or 1 (no pain) in 240 legs, 2 or 3 (uncomfortable) in 225 legs, and 4 or 5 (annoying) in 41 legs. Patients never experienced any pain higher than score 5. The statistical analysis revealed no significant difference between the pain scores of the right leg versus the left leg (p = 0.321) and between the pain scores after the femoral versus sciatic block (p = 0.7). Ultrasound-guided femoral and sciatic nerve blocks may provide considerable reduction of pain during endovenous laser and other treatments, such as ambulatory phlebectomy and foam sclerotherapy. They may make these procedures more comfortable for the patient and easier for the operator.

Although patient-controlled devices are frequently used in patients ≥6 years of age, alternative modes of analgesic delivery are needed in infants.Objective: To examine the safety and efficacy of nurse-controlled analgesia (NCA in neonates less than 1 year of age.Methods: Data from patients <1 year of age receiving NCA as ordered by the Acute Pain Service at our institution were collected over a 5-year period and reviewed retrospectively. The primary outcomes were activation of the institution’s Rapid Response Team (RRT or Code Blue, signifying severe adverse events. Pain score after NCA initiation was a secondary outcome.Results: Among 338 girls and 431 boys, the most common opioid used for NCA was fentanyl, followed by morphine and hydromorphone. There were 39 (5% cases involving RRT or Code Blue activation, of which only one (Code Blue was activated due to a complication of NCA (apnea. Multivariable logistic regression demonstrated morphine NCA to be associated with greater odds of RRT activation (OR=3.29, 95% CI=1.35, 8.03, P=0.009 compared to fentanyl NCA. There were no statistically significant differences in pain scores after NCA initiation across NCA agents.Conclusion: NCA is safe in neonates and infants, with comparable efficacy demonstrated for the three agents used. The elevated incidence of RRT activation in patients receiving morphine suggests caution in its use and consideration of alternative agents in this population.

    Full Text Available Background: Shoulder arthroplasty procedures are seldom performed on an ambulatory basis. Our objective was to examine postoperative analgesia, nausea and vomiting, patient satisfaction and complications of ambulatory shoulder arthroplasty performed using interscalene brachial plexus block (ISB. Materials and Methods: We prospectively examined 82 consecutive patients undergoing total and hemi-shoulder arthroplasty under ISB. Eighty-nine per cent (n=73 of patients received a continuous ISB; 11% (n=9 received a single-injection ISB. The blocks were performed using a nerve stimulator technique. Thirty to 40 mL of 0.5% ropivacaine with 1:400,000 epinephrine was injected perineurally after appropriate muscle twitches were elicited at a current of less than 0.5% mA. Data were collected in the preoperative holding area, intraoperatively and postoperatively including the postanesthesia care unit (PACU, at 24h and at seven days. Results: Mean postoperative pain scores at rest were 0.8 ± 2.3 in PACU (with movement, 0.9 ± 2.5, 2.5 ± 3.1 at 24h and 2.8 ± 2.1 at seven days. Mean postoperative nausea and vomiting (PONV scores were 0.2 ± 1.2 in the PACU and 0.4 ± 1.4 at 24h. Satisfaction scores were 4.8 ± 0.6 and 4.8 ± 0.7, respectively, at 24h and seven days. Minimal complications were noted postoperatively at 30 days. Conclusions: Regional anesthesia offers sufficient analgesia during the hospital stay for shoulder arthroplasty procedures while adhering to high patient comfort and satisfaction, with low complications.

There are several different clinical variations in the approaches used for achieving analgesia via TAP infiltration, and methods for identification of the TAP have evolved considerably since the landmark-guided technique was first described in 2001. There are many factors that impact the analgesic outcomes following TAP infiltration, and the various nuances of this technique have led to debate regarding procedural classification of TAP infiltration. Based on our current understanding of fascial and neuronal anatomy of the anterior abdominal wall, as well as available evidence from studies assessing local anesthetic spread and cutaneous sensory block following TAP infiltration, it is clear that TAP infiltration techniques are appropriately classified as field blocks. While the objective of peripheral nerve block and TAP infiltration are similar in that both approaches block sensory response in order to achieve analgesia, the technical components of the two procedures are different. Unlike peripheral nerve block, which involves identification or stimulation of a specific nerve or nerve plexus, followed by

    Opioids are widely used medicinally as analgesics and abused for hedonic effects, actions that are each complicated by substantial risks such as cardiorespiratory depression. These drugs mimic peptides such as β-endorphin, which has a key role in endogenous analgesia. The β-endorphin in the central nervous system originates from pro-opiomelanocortin (POMC) neurons in the arcuate nucleus and nucleus of the solitary tract (NTS). Relatively little is known about the NTSPOMC neurons but their position within the sensory nucleus of the vagus led us to test the hypothesis that they play a role in modulation of cardiorespiratory and nociceptive control. The NTSPOMC neurons were targeted using viral vectors in a POMC-Cre mouse line to express either opto-genetic (channelrhodopsin-2) or chemo-genetic (Pharmacologically Selective Actuator Modules). Opto-genetic activation of the NTSPOMC neurons in the working heart brainstem preparation (n = 21) evoked a reliable, titratable and time-locked respiratory inhibition (120% increase in inter-breath interval) with a bradycardia (125±26 beats per minute) and augmented respiratory sinus arrhythmia (58% increase). Chemo-genetic activation of NTSPOMC neurons in vivo was anti-nociceptive in the tail flick assay (latency increased by 126±65%, pmelanocortin receptor antagonist). The NTSPOMC neurons were found to project to key brainstem structures involved in cardiorespiratory control (nucleus ambiguus and ventral respiratory group) and endogenous analgesia (periaqueductal gray and midline raphe). Thus the NTSPOMC neurons may be capable of tuning behaviour by an opioidergic modulation of nociceptive, respiratory and cardiac control. PMID:27077912

    Full Text Available This study was carried out to assess the effect of nitroglycerine (transdermal on intrathecal neostigmine with bupivacaine on postoperative analgesia and note the incidence of adverse effects, if any. After taking informed consent, 120 patients of ASA Grade I and II were systematically randomised into four groups of 30 each. Patients were premedicated with midazolam 0.05 mg/kg intravenously and hydration with Ringer′s lactate solution 10ml/kg preoperatively in the holding room. Group I patients received Intrathecal injection of 15 mg bupivacaine with 1ml of normal saline and transdermal placebo patch. Group II patients received Intrathecal injection of 15 mg bupivacaine with 5 mcg of neostigmine and transdermal placebo patch. Group III patients received Intrathecal injection of 15 mg bupivacaine with 1ml of normal saline with transdermal nitroglycerine patch (5 mg/24 hours. Group IV patients received Intrathecal injection of 15 mg bupivacaine with 5mcg of neostigmine and transdermal nitroglycerine patch (5 mg/24 hours, applied on a non anaesthetised area after 20 minutes. Groups were demographically similar and did not differ in intraoperative characteristics like sensory block, motor block, haemodynamic parameters and SpO 2 . The mean duration of analgesia was 202.17 minutes, 407.20 minutes, 207.53 minutes and 581.63 minutes in control group (I, neostigmine group (II, nitroglycerine group (III and nitroglycerine neostigmine group (IV respectively (P< 0.01. To conclude, our results show that transdermal nitroglycerine itself does not show any analgesic potential but it enhances the analgesic potential of intrathecal neostigmine.

  8. An investigation of injection techniques for local analgesia of the equine distal tarsus and proximal metatarsus

    International Nuclear Information System (INIS)

    A positive radiographic contrast agent was injected into the tarsometatarsal (TMT) joints of both hindlimbs of 10 horses. Lateromedial radiographic views were obtained at 5, 15 and 30 mins after injection. Injection was successful in 19 of 20 limbs. Communication between the centrodistal (CD) and TMT joints was identified in 7 limbs (35%). Contrast agent extended around the tendons of tibialis cranialis (TC) and fibularis tertius (FT) in 18 limbs, and in 7 limbs some contrast entered the tarsal sheath. Slight to moderate plantar and/or distal extension of contrast agent was identified in 13 limbs. On a subsequent occasion positive contrast agent was injected subtarsally using one of two techniques and radiography was repeated. Contrast agent was principally distributed on the plantar aspect of the 3rd metatarsal bone, the plantar aspect of the suspensory ligament and between the superficial and deep digital flexor tendons. Extension of contrast agent into the TMT joint was identified in only 1 limb but in 8 limbs contrast agent extended into the tarsal sheath. The practical implications of these results include the possibility that local anaesthetic solution injected into the TMT joint may alleviate pain from the CD joint, the insertions of TC and FT or the tarsal sheath. It may also result in perineural analgesia of the dorsal metatarsal nerves or the plantar metatarsal nerves. In some cases subtarsal injection of local anaesthetic solution may result in alleviation of pain from the tarsal sheath. False negative results for subtarsal analgesia may be achieved by inadvertent injection into the tarsal sheath or into a blood or lymphatic vessel

    Pain catastrophizing is associated with greater levels of pain. While many studies support the efficacy of hypnosis for pain, the effect on pain catastrophizing remains unclear. The present study evaluated the effect of hypnosis on pain catastrophizing using experimental heat stimulation. Twenty-two pain patients engaged in 3 conditions: baseline (no suggestion), hypnotic induction, and hypnotic induction plus analgesia suggestion. Participants with higher baseline pain showed a significant reduction in rumination following hypnotic induction plus analgesia suggestion and significant reductions in pain due to both the hypnotic induction alone and the hypnotic induction plus analgesia suggestion. The findings suggest that unpleasantness-focused hypnotic analgesia reduces pain via its effect on the rumination component of pain catastrophizing. PMID:27585727

    Up to 75% of pre-hospital trauma patients experience moderate to severe pain but this is often poorly recognised and treated with insufficient analgesia. Using multi-level logistic regression analysis, we aimed to identify the determinants of pre-hospital analgesia administration and choice of analgesic agent in a single helicopter-based emergency medical service, where available analgesic drugs were fentanyl and ketamine. Of the 1156 patients rescued for isolated limb injury, 657 (57%) received analgesia. Mean (SD) initial pain scores (as measured by a numeric rating scale) were 2.8 (1.8), 3.3 (1.6) and 7.4 (2.0) for patients who did not receive, declined, and received analgesia, respectively (p administration. Fentanyl was preferred for paediatric patients and ketamine was preferentially administered for severe pain by physicians who had more medical experience or had trained in anaesthesia. PMID:27091515

    Full Text Available Central neuraxial blocked is one of the safest and efficacious methods of anaesthesia and analgesia. It has the added advantage of prolonged pain relief into the postoperative period. Epidural analgesia has increased steadily in popularity when compared to spinal anaesthes ia due to its neurological consequences and improved post - operative analgesia with epidural Opioids and as a consequence decreased side effects and prolonged the duration of analgesia. Present study is undertaken to compare hemodynamic and analgesic charac teristics using a 0.75% ropivacaine to a conventional dose of 0.5% bupivacaine for cesarean section under epidural anaesthesia. This study was conducted in ASA Grade I 50 singleton parturient to compare hemodynamics, APGAR scores and analgesic characterist ics of ropivacaine and bupivacaine. We have observed that the onset of sensory blockade was slower with ropivacaine and the duration of sensory blockade was also less. Whereas there was no significant change in haemodynamics and APGAR scores with both the drugs.

    Full Text Available OBJETIVOS: O plexo lombar foi localizado entre os músculos quadrado lombar e psoas maior. O objetivo deste estudo foi avaliar a eficácia da injeção única de bupivacaína 0,25% através do bloqueio do compartimento do psoas na analgesia pós-operatória em pacientes de cirurgias ortopédicas. MÉTODO: Quarenta pacientes receberam bloqueio do plexo lombar no compartimento do psoas através da localização com estimulador de nervos e injeção de bupivacaína a 0,25%. Avaliou-se a analgesia e a intensidade da dor às 4, 8, 12, 16, 20 e 24 horas após o término da cirurgia, assim como opióides de resgate. RESULTADOS: Os nervos ilioinguinal, genitofemoral, cutâneo femoral lateral, femoral e obturatório foram bloqueados em 90% dos pacientes. O bloqueio reduziu o regaste de opióides administrados, sendo que 52,5% dos pacientes não necessitaram de complementação analgésica, com duração de 24 horas. Não foram observados sinais e sintomas clínicos da toxicidade da bupivacaína, nem seqüelas associadas com o bloqueio dos nervos. CONCLUSÕES: Este estudo mostra que a injeção no espaço do compartimento do psoas é fácil de realizar com efetivo bloqueio dos cinco nervos. O bloqueio do plexo lombar no compartimento do psoas pode ser recomendado para o uso na analgesia pós-operatória após cirurgias ortopédicas.OBJECTIVES: The lumbar plexus is located between the quadratus lumborum and the psoas major muscles.

    Many studies have shown that hypothalamic paraventricular nucleus (PVN) plays a role in pain process, and endogenous opiate peptide system in the spinal cord is involved in nociception. This communication was designed to study the relationship between PVN and endogenous opiate system in the spinal cord in the rat. The results showed that in both the thoracic and the lumber spinal cord, microinjection of 100 ng L-glutamate sodium into PVN could increase leucine-enkephalin (L-Ek), beta-endorphin (beta-Ep), dynorphinA(1-13) (DynA(1-13)) concentrations and PVN cauterization decreased L-Ek and beta-Ep concentrations. Pretreatment of the spinal cord with 5 microg naloxone, an opiate receptor antagonist could partly reverse the analgesia induced by microinjection of 100 ng L-glutamate sodium into PVN. The data suggested that PVN analgesia might be involved in the endogenous opiate peptide system in the spinal cord independently. PMID:19452637

    1988-01-01

    The effects of exposure to clinical magnetic resonance imaging (MRI) on analgesia induced by the mu opiate agonist, fentanyl, was examined in mice. During the dark period, adult male mice were exposed for 23.2 min to the time-varying (0.6 T/sec) magnetic field (TVMF) component of the MRI procedure. Following this exposure, the analgesic potency of fentanyl citrate (0.1 mg/kg) was determined at 5, 10, 15, and 30 min post-injection, using a thermal test stimulus (hot-plate 50 degrees C). Exposure to the magnetic-field gradients attenuated the fentanyl-induced analgesia in a manner comparable to that previously observed with morphine. These results indicate that the time-varying magnetic fields associated with MRI have significant inhibitory effects on the analgesic effects of specific mu-opiate-directed ligands.

    Full Text Available Background and Aims: Caudal analgesia is one of the most popular regional blocks in paediatric patients undergoing infra-umbilical surgeries but with the drawback of short duration of action after single shot local anaesthetic injection. We evaluated whether caudal dexamethasone 0.1 mg/kg as an adjuvant to the ropivacaine improved analgesic efficacy after paediatric herniotomies. Methods: Totally 128 patients of 1–5 years age group, American Society of Anaesthesiologists physical status I and II undergoing elective inguinal herniotomy were randomly allocated to two groups in double-blind manner. Group A received 1 ml/kg of 0.2% ropivacaine caudally and Group B received 1 ml/kg of 0.2% ropivacaine, in which 0.1 mg/kg dexamethasone was added for caudal analgesia. Post operative pain by faces, legs, activity, cry and consolability tool score, rescue analgesic requirement and adverse effects were noted for 24 h. Results: Results were statistically analysed using Student's t-test. Pain scores measured at 1, 2, 4, and 6 h post-operative, were lower in Group B as compared to Group A. Mean duration of analgesia in Group A was 248.4 ± 54.1 min and in Group B was 478.046 ± 104.57 min with P = 0.001. Rescue analgesic requirement was more in Group A as compared to Group B. Adverse effects after surgery were comparable between the two groups. Conclusion: Caudal dexamethasone added to ropivacaine is a good alternative to prolong post-operative analgesia with less pain score compared to caudal ropivacaine alone.

    Recent data suggest that opioids can activate immune-like cells of the central nervous system (glia). This opioid-induced glial activation is associated with decreased analgesia, owing to the release of proinflammatory mediators. Here we examine in rats whether the putative microglial inhibitor, minocycline, may affect morphine-induced respiratory depression and/or morphine-induced reward (conditioned place preference). Systemic co-administration of minocycline significantly attenuated morphi...

    Full Text Available Background: Paravertebral block is a popular regional anesthetic technique used for perioperative analgesia in multiple surgical procedures. There are very few randomized trials of its use in laparoscopic cholecystectomy in medical literature. This study was aimed at assessing its efficacy and opioid-sparing potential in this surgery. Methods: Fifty patients were included in this prospective randomized study and allocated to two groups: Group A (25 patients receiving general anesthesia alone and Group B (25 patients receiving nerve-stimulator-guided bilateral thoracic Paravertebral Block (PVB at T6 level with 0.3 ml/kg of 0.25% bupivacaine prior to induction of general anesthesia. Intraoperative analgesia was supplemented with fentanyl (0.5 μg/kg based on hemodynamic and clinical parameters. Postoperatively, patients in both the groups received Patient-Controlled Analgesia (PCA morphine for the first 24 hours. The efficacy of PVB was assessed by comparing intraoperative fentanyl requirements, postoperative VAS scores at rest, and on coughing and PCA morphine consumption between the two groups. Results: Intraoperative supplemental fentanyl was significantly less in Group B compared to Group A (17.6 μg and 38.6 μg, respectively, P =0.001. PCA morphine requirement was significantly low in the PVB group at 2, 6, 12, and 24 hours postoperatively compared to that in Group A (4.4 mg vs 6.9 mg, 7.6 mg vs 14.2 mg, 11.6 mg vs 20.0 mg, 16.8 mg vs 27.2 mg, respectively; P <0.0001 at all intervals. Conclusion: Pre-induction PVB resulted in improved analgesia for 24 hours following laparoscopic cholecystectomy in this study, along with a significant reduction in perioperative opioid consumption and opioid-related side effects.

    1987-01-01

    During a social confrontation between a resident and an intruder mouse, only the submissive or defeated intruder shows an opioid-mediated analgesia to which tolerance develops. We investigated the altered morphine responsiveness after different kinds of social experiences. Mice were assessed for performance of operant behavior under the control of a fixed ratio schedule of positive reinforcement as well as for the tail flick response to a heat stimulus before and after one or five consecutive social confrontations. The dose-effect curves for morphine's suppression of schedule-controlled behavior were closely similar before and after defeat in a single or in five social confrontations. However, the concurrently measured response to pain in the tail flick assay produced morphine dose-effect curves that were shifted to the right after defeat in one or five social confrontations. Four to six times higher doses of morphine were necessary to produce analgesia in mice that were defeated in five social confrontations. Naltrexone (1 mg/kg, ip) antagonized the suppressive effects of morphine (10 mg/kg, ip) on rate of responding and the analgesic effects. Naltrexone also blocked the development of analgesia in mice that were defeated for the first time in a social confrontation, but did not prevent the suppressive effects on rate of responding. Specific social experiences such as defeat in a social confrontation appear to alter endogenous opioid process that mediate analgesia; these processes differ from those that suppress positively reinforced behavior. The differential development of morphine tolerance to the analgesic effects, but not the rate-decreasing effects as well as the differential naltrexone antagonism of both effects may indicate the involvement of opioid and non-opioid mechanisms.

    2013-01-01

    Full Text Available Background: Alpha 2 -adrenergic agonists have synergistic action with local anesthetics and may prolong the duration of sensory, motor blockade and postoperative analgesia obtained with spinal anesthesia. Aim: The objectives of this study are to compare and evaluate the efficacy of intravenous dexmedetomidine premedication with clonidine and placebo on spinal blockade duration, postoperative analgesia and sedation in patients undergoing surgery under bupivacaine intrathecal block. Materials and Methods: In this prospective, randomized, double-blind placebo-controlled study, 75 patients of the American Society of Anesthesiologists status I or II, scheduled for orthopedic lower limb surgery under spinal anesthesia, were randomly allocated into three groups of 25 each. Group DE received dexmedetomidine 0.5 μgkg−1 , group CL received clonidine 1.0 μgkg−1 and placebo group PL received 10 ml of normal saline intravenously before subarachnoid anesthesia with 15 mg of 0.5% hyperbaric bupivacaine. Onset time and regression times of sensory and motor blockade, the maximum upper level of sensory blockade were recorded. Duration of postoperative analgesia and sedation scores along with side effects were also recorded. Data was analyzed using analysis of variance or Chi-square test, and the value of P < 0.05 was considered statistically significant. Results: The sensory block level was higher with dexmedetomidine (T4 ± 1 than clonidine (T6 ± 1 or placebo (T6 ± 2. Dexmedetomidine also increased the time (243.35 ± 56.82 min to first postoperative analgesic request compared with clonidine (190.93 ± 42.38 min, P < 0.0001 and placebo (140.75 ± 28.52 min, P < 0.0001. The maximum Ramsay sedation score was greater in the dexmedetomidine group than other two groups (P < 0.0001. Conclusion: Premedication with intravenous dexmedetomidine is better than intravenous clonidine to provide intraoperative sedation and postoperative analgesia during bupivacaine

    The effects of the alpha-adrenoceptor antagonists prazosin, phentolamine and yohimbine upon 5-methoxy-N,N-dimethyltryptamine (5-MeODMT)-induced analgesia were tested in the hot-plate, tail-flick and shock-titration tests of nociception with rats. Intrathecally injected yohimbine and phentolamine blocked or attenuated the analgesia produced by systemic administration of 5-MeODMT in all three nociceptive tests. Intrathecally administered prazosin attenuated the analgesic effects of 5-MeODMT in the hot-plate and tail-flick tests, but not in the shock titration test. Intrathecal yohimbine showed a dose-related lowering of pain thresholds in saline and 5-MeODMT-treated animals. Phentolamine and prazosin produced normal dose-related curves in the hot-plate test and biphasic effects in the shock titration and tail-flick tests. These results demonstrate a functional interaction between alpha 2-adrenoceptors and 5-HT agonist-induced analgesia at a spinal level in rats. PMID:2877697

    Full Text Available Regional anesthesia is widely used for abdominal hysterectomies. It is divided into spinal and epidural anaesthesia. Epidural anesthesia has got the advantage of extending the period of anesthesia to post-operative analgesia. We can use various pharmacological agents as adjuvants, which prolong the duration of action of local anesthetics. They include opiods, alpha 2 agonists like clonidine and dexmedetomidine. In this we studied the efficacy of local anesthetic agent – ropivacaine alone, ropivacaine with clonidine and ropivacaine with dexmedetomidine for epidural block. Present study showed that Epidural Dexmedetomidine and clonidine have synergistic action in combination with epidural ropivacaine resulting in smooth and prolonged postoperative analgesia and sedation. Group RD (Ropivacaine and Dexmedetomidine had significant difference in comparison of postoperative block characteristics, such as time of two segment regression, time to Bromage scale 1, time of regression to S1 dermatome and time of first epidural top up than group RC and R. (Ropivacaine with clonidine and Ropivacaine alone. Thus epidural dexmedetomidine is a better neuraxial adjuvant in combination with epidural ropivacaine in producing prolonged analgesia and better sedation for abdominal hysterectomy

    Tricyclic antidepressants (TCAs) are found to have an analgesic action for relieving cutaneous pain associated with neuropathies. The aim of this study was to assess cutaneous absorption and analgesia of topically applied TCAs. Percutaneous delivery was investigated using nude mouse and pig skin models at both infinite and saturated doses. We evaluated the cutaneous analgesia in nude mice using the pinprick scores. Among five antidepressants tested in the in vitro experiment, mesoridazine, promazine and doxepin showed a superior total absorption percentage. The drug with the lowest total absorption percentage was found to be fluphenazine (dose or at saturated solubility. The follicular pathway was important for mesoridazine and promazine delivery. Mesoridazine showed stronger skin analgesia than the other TCAs although the in vivo skin absorption of mesoridazine (0.34nmol/mg) was less than that of promazine (0.80nmol/mg) and doxepin (0.74nmol/mg). Mesoridazine had a prolonged duration of pain relief (165min) compared to promazine (83min) and doxepin (17min). The skin irritation test demonstrated an evident barrier function deterioration and cutaneous erythema by promazine and doxepin treatment, whereas mesoridazine caused no obvious adverse effect by topical application for up to 7days.

    Full Text Available Gran especialista en historia moderna, Alberto Tenenti nació en Viareggio, en 1924. Tras realizar estudios superiores en Italia, trabajó en el Centre National de la Recherche Scientifique varios años, asesorado por Lucien Febvre. Ha dirigido el Archivo del Estado de Brescia; y, más tarde, ha enseñado en París, desde una cátedra en la École Pratique des Hautes Études en Sciences Sociales (VI Sección, alIado de Braudel. Su Il senso della morte e l'amore della vita nel Rinascimento, de 1957, es una obra maestra sobre los orígenes de la sensibilidad moderna: sin olvidar el naciente vitalismo, estudia el desarrollo de dos motivos, el del ars moriendi, que tiene su evolución propia desde 1350 hasta su difusión impresa, y el de lo macabro, que refleja la crisis de conciencia del siglo XV y adquiere «unas dimensiones desconocidas y verdaderamente anormales». En este libro sobre un problema clave como la muerte, apela de modo notable a la iconografía: Tenenti ha recordado que la cultura tradicional, eclesiástica sobre todo, percibió un mayor peligro en la capacidad de reflexión autónoma y de crítica de los hombres de letras, que en las renovaciones radicales de los artistas. Numerosos trabajos de conjunto realizados por él han perseguido una historia global: Los fundamentos del mundo moderno; Florencia en la época de los Medicis; La formación del mundo moderno; El Renacimiento; el primero de ellos estaba firmado con un historiador de su misma generación, R.

    AIM: To investigate the influence of repeated water avoidance stress (rWAS) on the visceromotor response (VMR) to colorectal distension (CRD) and the modulation of the response by a prebiotic diet in rats using a novel surgery-free method of solid-state manometry.METHODS: Male Wistar rats fed a standard diet with or without 4% enzyme-treated rice fiber (ERF) for 5 wk were subjected to rWAS (1 h daily x 10 d) or no stress. The VMR to graded phasic CRD was assessed by intraluminal colonic pressure recording on days 0 (baseline), 1 and 10 (45 min) and 11 (24 h) after rWAS and expressed as percentage change from baseline. Cecal content of short chain fatty acids and distal colonic histology were assessed on day 11.RESULTS: WAS on day 1 reduced the VMR to CRD at 40 and 60 mmHg similarly by 28.9% ± 6.6% in both diet groups. On day 10, rWAS-induced reduction of VMR occurred only at 40 mmHg in the standard diet group (36.2% ± 17.8%) while in the ERF group VMR was lowered at 20, 40 and 60 mmHg by 64.9% ± 20.9%, 49.3% ± 11.6% and 38.9% ± 7.3% respectively. The visceral analgesia was still observed on day 11 in ERF- but not in standard diet-fed rats. By contrast the non-stressed groups (standard or ERF diet) exhibited no changes in VMR to CRD. In standard diet-fed rats, rWAS induced mild colonic histological changes that were absent in ERF-fed rats exposed to stress compared to non-stressed rats. The reduction of cecal content of isobutyrate and total butyrate, but not butyrate alone, was correlated with lower visceral pain response. Additionally, ERF diet increased rWAS-induced defecation by 26% and 75% during the first 0-15 min and last 15-60 min, respectively, compared to standard diet, and reduced rats' body weight gain by 1.3 fold independently of their stress status. CONCLUSION: These data provide the first evidence of psychological stress-related visceral analgesia in rats that was enhanced by chronic intake of ERF prebiotic.

    Full Text Available Questions: In the active phase of the first stage of labour, does transcutaneous electrical nerve stimulation (TENS relieve pain or change its location? Does TENS delay the request for neuraxial analgesia during labour? Does TENS produce any harmful effects in the mother or the foetus? Are women in labour satisfied with the care provided? Design: Randomised trial with concealed allocation, assessor blinding for some outcomes, and intention-to-treat analysis. Participants: Forty-six low-risk, primigravida parturients with a gestational age > 37 weeks, cervical dilation of 4 cm, and without the use of any medications from hospital admission until randomisation. Intervention: The principal investigator applied TENS to the experimental group for 30 minutes starting at the beginning of the active phase of labour. A second investigator assessed the outcomes in both the control and experimental groups. Both groups received routine perinatal care. Outcome measures: The primary outcome was pain severity after the intervention period, which was assessed using the 100-mm visual analogue scale. Secondary outcomes included: pain location, duration of the active phase of labour, time to pharmacological labour analgesia, mode of birth, neonatal outcomes, and the participant's satisfaction with the care provided. Results: After the intervention, a significant mean difference in change in pain of 15 mm was observed favouring the experimental group (95% CI 2 to 27. The application of TENS did not alter the location or distribution of the pain. The mean time to pharmacological analgesia after the intervention was 5.0 hours (95% CI 4.1 to 5.9 longer in the experimental group. The intervention did not significantly impact the other maternal and neonatal outcomes. Participants in both groups were satisfied with the care provided during labour. Conclusion: TENS produces a significant decrease in pain during labour and postpones the need for pharmacological

    Full Text Available The present randomized study was conducted in our institute of pulmonary medicine and tuberculosis over a period of 1 year. This study aimed to evaluate the effectiveness of transcutaneous electrical nerve stimulation (TENS as an adjunctive to thoracic epidural analgesia for the treatment of postoperative pain in patients who underwent posterolateral thoracotomy for decortication of lung. Sixty patients in the age group 15-40 years scheduled to undergo elective posterolateral thoracotomy were divided into two groups of 30 each. Patients were alternatively assigned to one of the groups. In group I, only thoracic epidural analgesia with local anaesthetics was given at regular intervals; however, an identical apparatus which did not deliver an electric current was applied to the control (i.e. group I patients. While in group II, TENS was started immediately in the recovery period in addition to the epidural analgesia. A 0-10 visual analog scale (VAS was used to assess pain at regular intervals. The haemodynamics were also studied at regular intervals of 2 h for the first 10 h after the surgery. When the VAS score was more than three, intramuscular analgesia with diclofenac sodium was given. The VAS score and the systolic blood pressure were comparable in the immediate postoperative period (P = NS but the VAS score was significantly less in group II at 2, 4, 6, 8 h (P < 0.01, P < 0.05, P < 0.05, P < 0.05, respectively, and at 10 h the P value was not significant. Similarly, the systolic blood pressure was significantly less in group II at 2, 4, 6 h after surgery, that is P < 0.02, P < 0.01, P < 0.01, respectively, but at 8 and 10 h the pressures were comparable in both the groups. Adding TENS to epidural analgesia led to a significant reduction in pain with no sequelae. The haemodynamics were significantly stable in group II compared to group I. TENS is a valuable strategy to alleviate postoperative pain following thoracic surgery with no side

    Full Text Available CONTEXT : Post - operative pain after laparoscopic cholecystectomy is less than open cholecystectomy, but many patients require strong analgesia postoperatively. Intraperitoneal administration of local anaesthetics alone or in combination with various adjuvan ts can control post - operative pain. AIM : To compare the analgesic effect of the intraperitoneal administration of Bupivacaine, Bupivacaine plus Tramadol and Bupivacaine plus Dexmedetomidine. SETTINGS AND DESIGN: 80 patients undergoing laparoscopic cholecys tectomy were randomly allocated to one of four groups: Group C; Group B, Group T and Group D. METHODS AND MATERIAL : 80 patients undergoing laparoscopic cholecystectomy were randomly allocated to one of four groups: Group C received 20 ml of saline; Group B received 20 ml of 0.25% Bupivacaine. Group T received 20 ml of 0.25% Bupivacaine with 100 mg Tramadol and patients allocated to Group D received 20 ml of 0.25% Bupivacaine with 1μg/kg of Dexmedetomidine intraperitoneally post - operatively. Faces pain scale was recorded at 0.5, 1, 2, 4, 6 and 24 hours postoperatively. Time of requirement of rescue analgesia was calculated. Level of sedation postoperatively was assessed. Incidence of postoperative nausea and vomiting (PONV was also recorded. STATISTICAL ANAL YSIS : Data was analyzed by two - way analysis of variance, Student’s t - test, Kruscal - Walis and Mann - Whitney U - test. RESULTS : Pain intensity, time of requirement of rescue analgesia, sedation score, as well as PONV were significantly lower in Group D, Group T and Group B than in Group C. Duration of post - operative analgesia was highest with Bupivacaine plus Dexmedetomidine. Ther e were no differences between the three groups receiving Bupivacaine and Bupivacaine with Tramadol and Bupivacaine with Dexmedetomidine in FPS score, incidence of PONV and postoperative analgesic and antiemetic consumption. CONCLUSIONS : Bupivacaine with or without adjuvants provides

    Full Text Available Las vacunas de células diploides humanas (WI-38, MRC-5 tienen un origen éticamente objetable, dado que dichas células proceden de abortos provocados. Entre ellas destacan vacunas empleadas contra rubéola, sarampión, parotiditis, rabia, poliomielitis, viruela, hepatitis A, varicela y herpes zóster. Actualmente se encuentran en desarrollo otras vacunas cultivadas en células (293, PER.C6 transformadas mediante virus, procedentes de abortos. Entre ellas hay vacunas contra la gripe, virus respiratorio sincitial, parainfl uenza, HIV, virus del Nilo Occidental, virus Ébola, Marburg y Lassa, hepatitis B y C, glosopeda, encefalitis japonesa, dengue, tuberculosis, carbunco, peste, tétanos y paludismo. También con igual origen se trabaja en la elaboración de anticuerpos monoclonales y otras proteínas, terapia génica y genómica. Existe la tecnología necesaria para producir todo lo descrito sin recurrir a abortos provocados. Debe indicarse en los prospectos de vacunas y otros productos el origen de las células empleadas. Debe facilitarse el acceso a las vacunas existentes no cultivadas en células procedentes de abortos provocados. Debe potenciarse la investigación de opciones en aquellos casos en los que no exista una vacuna no originada en células procedentes de abortos provocados. Debe potenciarse la elaboración de anticuerpos monoclonales y de otras proteínas, así como la terapia génica y la genómica sin recurrir a células procedentes de abortos provocados. No sería consecuente rechazar productos obtenidos a partir de células troncales embrionarias y aceptar los originados en células procedentes de abortos provocados. Se debe evitar que la biotecnología basada en el aborto provocado invada todos los terrenos de la medicina.

    The aim of the present study was to investigate the role of the amygdala in the potentiative effect of minocycline, a semisynthetic tetracycline antibiotic, on morphine analgesia in male Wistar rats. We also examined the involvement of the amygdala μ-opioid and N-methyl-D-aspartate (NMDA) receptors in the minocycline-induced potentiation of morphine analgesia. Intraperitoneal administration of morphine (3-9 mg/kg) induced analgesia in a tail-flick test. Bilateral intra-amygdala injection of minocycline (10-20 μg/rat) enhanced the analgesic response of an ineffective dose of morphine (3 mg/kg). Injection of a higher dose of minocycline into the amygdala also induced analgesia. Moreover, bilateral intra-amygdala injection of naloxone (0.5-1.5 µg/rat) reversed minocycline-induced potentiation of morphine analgesia. Pretreatment of animals with NMDA (0.01-0.1 μg/rat, intra-amygdala) also inhibited the potentiative effect of minocycline on morphine response. Bilateral intra-amygdala injection of the same doses of naloxone or NMDA plus morphine had no effect on the tail-flick latency in the absence of minocycline. It can be concluded that the amygdala has a key role in the potentiative effect of minocycline on morphine analgesia. In addition, amygdala opioidergic and glutamatergic mechanisms may be involved, probably through μ-opioid and NMDA receptors, in the modulation of the minocycline-induced potentiation of morphine analgesia in the tail-flick test.
