    Full Text Available Presentamos un caso clínico de espasmos vesicales por hiperactividad del detrusor de la vejiga, desencadenados por lavado vesical continuo aplicado en un paciente con hematuria, en el contexto de hipertrofia benigna de próstata. Los espasmos llegaron a ser refractarios a tratamiento sistémico con antimuscarínicos, espasmolíticos y opioides. Se optó por la colocación de un catéter epidural lumbar para infusión continua de anestésicos locales y opioides como terapia analgésica alternativa, que no solo proporcionó un aceptable grado de confort, sino que permitió el mantenimiento del sondaje uretral y el lavado vesical continuo. Realizamos una revisión bibliográfica sobre el uso del bloqueo epidural de la neurotransmisión de las aferencias sensitivas vesicales en dolor de origen disfuncional vesical, y analizamos algunas de la teorías publicadas sobre la fisiopatología y génesis de dolor en estos trastornos vesicales, con la intención de interpretar las peculiaridades y complejidad del dolor en el cuadro del caso presentado.We present a clinical case of bladder spasms due to detrusor overactitivity, triggered by continuous vesicoclysis therapy, which was applied in a patient with benign prostatic hypertrophy-related hematuria. Bladder spasms turned out to be refractory to combined antimuscarinic, spasmolytic and systemic opioid therapies. Implantation of a lumbar epidural catheter was chosen for continuous epidural infusion of local anesthetics and opioid drugs as an alternate analgesic therapy, which provided the patient an optimum comfort, but let urethral indwelling catheterization and the maintenance of continuous vesicoclysis therapy as well. We reviewed scientific literature concerning bladder-afferent neurotransmission blockade at epidural level for dysfunctional bladder pain therapy, and discussed several published theories about pain physiopathology and origin in those cases of dysfunctional bladder disturbance, with the

El objetivo del estudio, fue evaluar si el bloqueo del plexo lumbar combinado con la anestesia general, equivale a la anestesia epidural lumbar en cuanto a la eficacia del bloqueo nociceptivo, efectos hemodinámicos secundarios, dificultad en su ejecución e influencia en el sangramiento operatorio en pacientes sometidos a la ATC. MÉTODO: Pacientes estado físico ASA I a III que fueron ubicados aleatoriamente en los grupos Epidural y Lumbar. En el grupo Epidural, se realizó la anestesia epidural lumbar continua con la ropivacaína a 0,5% 10 a 15 mL. En el grupo Lumbar, fue realizado el bloqueo del plexo lumbar por la vía posterior con ropivacaína a 0,5% 0,4 mL.kg-1. Todos los pacientes fueron sometidos a la anestesia general. Se estudiaron: la dificultad en la ejecución de los bloqueos, su eficacia y los efectos hemodinámicos secundarios. RESULTADOS: Cuarenta y un pacientes fueron incluidos en el estudio. El tiempo para la ejecución del bloqueo epidural fue menor, pero el número de intentos en colocar la aguja fue similar en los dos grupos. El bloqueo epidural fue más eficaz. En el grupo Lumbar, se registró un aumento de la presión arterial diastólica y media (PAM y en el doble producto. Después de la incisión, el consumo anestésico durante la operación fue mayor. Posteriormente al bloqueo, la PAM fue menor en los 50, 60 y 70 minutos después de la realización del bloqueo epidural. El sangramiento fue parecido en los dos grupos. CONCLUSIONES: La técnica epidural promovió un bloqueo nociceptivo más eficaz sin asociarse a la inestabilidad hemodinámica, cuando se le combinó con la anestesia general. El bloqueo del plexo lumbar fue una técnica útil en combinación con la anestesia general cuando la anestesia epidural estuvo contraindicada.BACKGROUND AND OBJECTIVES: Anesthesia for total hip arthroplasty (THA is a challenge due to the advanced age and associated diseases of patients.

    Full Text Available El Síndrome de Horner es una complicación de la anestesia epidural que aparece más frecuentemente en pacientes obstétricas debido a los cambios fisiológicos y anatómicos propios del embarazo; sin embargo, su incidencia es baja, y sólo se han descrito dos casos previos asociando un bloqueo del plexo braquial. Presentamos el caso de una gestante de 23 años que precisó analgesia epidural para el trabajo de parto. Tras comprobar la correcta colocación del catéter se administró una dosis inicial en bolo de 8 ml de ropivacaína 0,2% y 50 μgr de fentanilo, y se iniciσ una perfusión de ropivacaína a 0,125% y fentanilo a 1,2 μg/ml a 10 mg/h. Tras cuatro horas de perfusión, la paciente alcanza dilatación completa y pasa a quirófano para realizar prueba de parto. Allí se administró una dosis de refuerzo por vía epidural con 10 ml de ropivacaína 0,5% y 50 μg de fentanilo. A los 15 minutos, la paciente comenzó a manifestar un cuadro de disestesias en hemicara derecha y miembro superior derecho. A continuación, estando ya la paciente en la zona de recuperación la paciente refirió bloqueo motor y sensitivo de miembros inferiores asociado a pérdida de fuerza de miembro superior derecho y ptosis palpebral, miosis con ligero enrojecimiento de ojo derecho, siendo diagnosticado como síndrome de Horner con bloqueo del plexo braquial ipsilateral, desapareciendo espontáneamente en las tres horas siguientes.Horner´s syndrome is an uncommon side effect after epidural analgesia which occurs more frecuently in pregnant women due to physiological and anatomical changes; however, it has a low incidence, and the association with ipsilateral brachial plexus block has only been published twice before. We report the case of a 23-year-old woman who required epidural analgesia for labor. After verifying correct placement of the catheter, an initial dose of 8 ml of ropivacaine 0,2% with 50 μg of fentanyl was injected. A continuous infusion of

RESULTADOS: No hubo diferencia entre la latencia, bien como en el nivel máximo de bloqueo entre los grupos. La ausencia de bloqueo motor fue el resultado más frecuente, encontrado en cerca de 64% de los pacientes. El intervalo de analgesia fue diferente entre los grupos, siendo más significativo en el grupo III. CONCLUSIONES: El uso de la clonidina, asociada o no al fentanil, prolongó el tiempo de analgesia pós-operatoria en la anestesia peridural sacral con lidocaína.BACKGROUND AND OBJECTIVES: The association of different substances to local anesthetics aims to improve the blockade quality and prolonging analgesia. The aims of this study were to compare the effectiveness of the association of clonidine, clonidine and fentanyl, and fentanyl, to lidocaine for postoperative analgesia. METHODS: Participated in this study 64 patients aged 23 years or above, physical status ASA I or II, undergoing to orificial proctologic surgery under epidural caudal anesthesia. Patients were distributed in 4 groups of 16: group I (lidocaine alone; group II (lidocaine and fentanyl; group III (lidocaine, fentanyl and clonidine; and group IV (lidocaine and clonidine. The quality of sensory and motor blockade were compared. RESULTS: There has been no difference in onset and maximum block level among groups. Absence of motor block was the most frequent result, found in about 64% of patients. Analgesia length was different among groups, being more significant in group III. CONCLUSIONS: Clonidine, associated or not to fentanyl, has prolonged postoperative analgesia after epidural caudal blockade with lidocaine.

Los bloqueos de nervios periféricos han sido indicados como procedimientos con una baja incidencia de complicaciones y un tiempo prolongado de analgesia. El objetivo del estudio actual, fue comparar el tiempo de analgesia de los bloqueos nerviosos periféricos y del bloqueo caudal y el consumo de morfina, en las primeras 24 horas después de la corrección de PJC en niños. MÉTODO: Estudio randómico doble ciego, en niños sometidos a la intervención quirúrgica para liberación posteromedial de PJC, ubicadas en cuatro grupos conforme a la técnica anestésica: caudal (ACa; bloqueos isquiático y femoral (IF; bloqueos isquiático y safeno (IS; bloqueo isquiático y anestesia local (IL, asociados a la anestesia general. En las primeras 24 horas, los pacientes recibieron dipirona y paracetamol vía oral y fueron evaluados por un anestesiólogo que no conocía la técnica usada. Conforme a las puntuaciones de la escala CHIPPS (Children's and infants postoperative pain scale, se administraba morfina vía oral (0,19 mg.kg-1 por día. RESULTADOS: Fueron estudiados 118 niños distribuidos en los grupos ACa (30, IF (32, IS (28 IL (28. El tiempo promedio entre el bloqueo y la primera dosis de morfina fue de 6,16 horas en el grupo ACa, 7,05 horas en el IF, 7,58 horas en el IS y 8,18 horas en el IL. El consumo de morfina fue de 0,3 mg.kg-1 por día en los cuatro grupos. No hubo diferencia significativa entre los grupos. CONCLUSIONES: Los bloqueos nerviosos periféricos no promovieron un tiempo más elevado de analgesia, ni tampoco una reducción en el consumo de morfina en las primeras 24 horas, en niños sometidos a la corrección de PJC cuando se les comparó con el bloqueo epidural caudal.BACKGROUND AND OBJECTIVES: Correction of congenital clubfoot (CCF is associated with

    Full Text Available Los bloqueos nerviosos periféricos pueden ser una alternativa a la analgesia intravenosa y epidural en el tratamiento del miembro fantasma doloroso. La dificultad en la localización del nervio ciático mediante neuroestimulación en pacientes con arteriopatía periférica y neuropatía puede verse aumentada por el hecho de presentar una amputación del miembro inferior, que imposibilita la observación de una respuesta motora en el pie coincidiendo con la localización del nervio. En estos casos, la ecografía puede convertirse en una técnica de localización nerviosa determinante del éxito de la analgesia ya que permite la identificación del nervio, así como la visualización en tiempo real de la posición relativa de la aguja y catéter respecto al nervio y la difusión del anestésico local administrado. Se presenta el caso de un paciente con miembro fantasma doloroso resistente al tratamiento convencional que se controló con un bloqueo ciático continuo con catéter estimulador guiado con ecografía.Peripheral nerve blocks can be an alternative to intravenous and epidural analgesia in the treatment of phantom limb pain. The difficulty of localizing the sciatic nerve through neurostimulation in patients with peripheral arteriopathy and neuropathy can be increased by lower limb amputation, making it impossible to observe a motor response in the foot coinciding with localization of the nerve. In these cases, ultrasonography can become a technique for nerve localization and determine the success of analgesic strategy, since it allows nerve identification, as well as visualization in real time of the relative position of the needle and catheter with respect to the nerve and the diffusion of the local anesthetic administered. We report the case of a patient with phantom limb pain refractory to conventional treatment, in whom pain control was achieved by ultrasound-guided continuous sciatic block with stimulating catheter.

    Full Text Available El bloqueo facetario es un procedimiento usado en aquellos pacientes con artrosis facetaria en los cuales han fallado los múltiples tratamientos médicos. En nuestro país se desconocen estudios o estadísticas que demuestren su efectividad, por lo que se consideró pertinente demostrarlo. Se realizó un estudio observacional retrospectivo de una cohorte de pacientes intervenidos en el período comprendido entre enero de 2005 y diciembre de 2009 en la Clínica CES. Se recolectó información de las historias clínicas mediante un formulario diseñado para tal fin; además se relacionó la existencia de mejoría del paciente posterior a la intervención con edad, sexo, ocupación, tiempo de evolución, síntomas motores y sensitivos previos y enfermedades asociadas. La población fue de 232 pacientes entre 21 y 92 años, con una edad promedio de 56,9 (± 14,6 años, con un tiempo de evolución del dolor lumbar de 2 años en el 40% de la población estudiada. La resonancia magnética fue el estudio más utilizado previo al procedimiento en 42,2% de los pacientes, la tomografía en 38,31% y los rayos X en 7,46%. El procedimiento fue eficaz en el 78% de los pacientes. En conclusión, el bloqueo facetario es un método terapéutico, ya que se vio mejoría de la sintomatología en la mayoría de los pacientes estudiados. Esto es coherente con otros estudios realizados, donde también se ha evidenciado disminución de las limitaciones físicas y funcionales de los pacientes. Además, es un procedimiento diagnóstico ya que la mejoría con esta técnica indica que la patología sí era facetaria.Facet block is a procedure used in patients with facet arthrosis in which several other medical techniques have failed.

    . El objetivo de este estudio fue comparar el bloqueo de los nervios supraescapular y axilar en las cirugías artroscópicas de hombro con el abordaje interescalénico del plexo braquial. MÉTODO: Sesenta y ocho pacientes fueron ubicados en dos grupos de 34, de acuerdo con la técnica utilizada: grupo Interescalénico (GI y grupo selectivo (GS, siendo ambos abordajes realizados con neuroestimulador. En el GI, y después de la respuesta motora adecuada, se inyectaron 30 mL de levopubivacaina en exceso enantiomérico de un 50% al 0,33% con adrenalina 1:200.000. En el GS, y después de la respuesta motora del nervio supraescapular y axilar, se inyectaron 15 mL de la misma sustancia en cada nervio. Enseguida se realizó la anestesia general. Las variables que se evaluaron fueron: tiempo para la realización de los bloqueos, analgesia, consumo de opioide, bloqueo motor, estabilidad cardiocirculatoria, satisfacción y aceptabilidad por parte del paciente. RESULTADOS: El tiempo para la ejecución del bloqueo interescalénico fue significativamente menor que para la realización del bloqueo selectivo. La analgesia fue significativamente mayor en el postoperatorio inmediato en el GI y en el postoperatorio tardío en el GS. El consumo de morfina fue significativamente mayor en la primera hora en el GS. El bloqueo motor fue significativamente menor en el GS. La estabilidad cardiocirculatoria, satisfacción y aceptabilidad de la técnica por el paciente no fueron diferentes entre los grupos. Ocurrió un fallo en el GI y dos en el GS. CONCLUSIONES: Ambas técnicas son seguras y eficaces con el mismo grado de satisfacción y de aceptabilidad. El bloqueo selectivo de ambos nervios presentó una analgesia satisfactoria, con la ventaja de proporcionar un bloqueo motor restringido al hombro.BACKGROUND AND OBJECTIVE: Shoulder arthroscopic surgeries evolve with intense postoperative pain.

    2006-04-01

    Full Text Available Introducción: La ketamina de uso corriente es una droga utilizada principalmente para la inducción y el mantenimiento de la anestesia, compuesta por una mezcla racémica de enantiómeros R (- y S (+. En la década de los años 80 comienza la administración humana de la ketamina por vía epidural. A partir de entonces se han presentado disímiles investigaciones para justificar su acción analgésica en este espacio con varias hipótesis: 1 supresión específica laminar de las astas dorsales, 2 mediación por el sistema opioide endógeno y sustancia gris periacueductal, y 3 bloqueo de los canales del calcio por antagonismo no competitivo de los receptores N-metil-d-aspartato. Objetivo: Demostrar la eficacia de la ketamina por vía epidural como analgésico postoperatorio en la cirugía de hemiabdomen inferior. Material y Método: Se realizó un ensayo clínico aleatorizado y prospectivo en una muestra de 50 pacientes operados de hernia inguinal electiva. Los pacientes fueron divididos en dos grupos, un grupo tratado con 50 mg de ketamina y otro grupo al que se le administró una dosis de 2 mg de morfina liofilizada. Resultados: la ketamina por vía epidural en una dosis de 50 mg proporciona una analgesia adecuada por un período de al menos de 6 horas. La morfina brinda una analgesia por encima de las 18 horas. Conclusión: La ketamina por vía epidural es menos efectiva que la morfina desde el punto de vista analgésico, pero es una alternativa importante pues permite disminuir la dosis de morfina si se combinan ambos fármacos o se asocia a anestésicos locales.Introduction: Ketamine is a drug used for induction and maintenance of anesthesia, exists as a racemic mixture of R- and S+-enantiomers.

    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. Avisan al Servicio de Anestesia para valoración de la indicación de epidural para analgesia del parto. 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 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.

    Full Text Available Las intoxicaciones por alcohol y drogas de abuso son una causa frecuente de consulta en los Servicios de Urgencias. Las alteraciones electrocardiográficas y las arritmias debidas a la ingesta de alcohol se conocen como Holiday Heart Syndrome. Este síndrome se define como la presencia de alteraciones del ritmo o de la conducción cardiaca asociadas al consumo de alcohol que revierten tras la intoxicación y que se producen en una persona sin enfermedad cardiaca conocida. La alteración más común es la fibrilación auricular. Se presenta el caso de una paciente joven que ingresa en urgencias por intoxicación por alcohol y diferentes drogas y que presentaba un bloqueo auriculoventricular de primer grado transitorio. Se discute el posible efecto causal de las drogas y del alcohol en los cambios electrocardiográficos observados en esta paciente.

    Full Text Available Introducción: El fenómeno de Raynaud es un trastorno vascular, frecuente en la población general, que consiste en la aparición paroxística de espasmo vascular distal, en pequeñas arterias y arteriolas cutáneas de las extremidades, con escasa repercusión sistémica. Existen bases anatómicas y fisiológicas para producir un bloqueo simpático selectivo utilizando agentes neurolíticos en los ganglios torácicos T2 y T3, considerados estaciones sinápticas que se distribuyen en el miembro superior. Objetivo: Determinar la eficacia del bloqueo neurolítico del tercer ganglio dorsal en el síndrome de Raynaud de una serie de casos. Material y métodos: Se realizó la revisión de expedientes de una serie de ocho casos con fenómeno de Raynaud de causa multifactorial, en la Clínica del Dolor de la Unidad Médica de Alta Especialidad Monterrey; Nuevo León, México. Casos: Ocho casos de 41 a 72 años de edad con fenómeno de Raynaud, tratados médicamente, a los cuales se les realizaron simpaticolisis del tercer ganglio dorsal. Conclusiones: El fenómeno de Raynaud tiene una prevalencia que va del 1 al 25%, en este hay una actividad simpática aumentada por lo que al realizar una simpaticolisis selectiva se logra mejorar el dolor isquémico, el cual está determinado por la insuficiencia total o parcial en el aporte de oxígeno a los tejidos, además de que tenemos bases anatómicas y fisiológicas para limitar el bloqueo a los ganglios T2 y T3, considerados como las estaciones sinápticas que interrumpen los impulsos que se distribuyen en el miembro superior, siendo por tanto más selectivos y con menores efectos adversos para el paciente.Background: Raynaud's phenomenon, a vascular disorder that is common in the general population, consists of paroxysmal onset distal vasospasm in small cutaneous arteries and arterioles of extremities, usually with little systemic impact. There are anatomical and physiological bases to produce a selective

    Full Text Available En este artículo se describe el estudio de los fenómenos de bloqueo y ensombrecimiento en una tarea de aprendizaje espacial en un anfibio, el sapo terrestre Rhinella arenarum. Ambos fenómenos de aprendizaje, ampliamente observados en otras clases de vertebrados, se describen por primera vez en un grupo con un cerebro filogenéticamente antiguo, como es el caso de los anfibios. Específicamente, se observó durante el aprendizaje espacial: (1 bloqueo entre claves visuales asociadas a una meta, y (2 ensombrecimiento de una clave visual lejana por la presencia de una clave cercana. Este hecho permite sentar un precedente para estudiar posteriormente los mecanismos biológicos que rigen el aprendizaje espacial, en búsqueda de patrones funcionales comunes con otras clases de vertebrados, potencialmente presentes en un ancestro común.

    Full Text Available Introducción: Los efectos del trabajo continuado y nocturno sobre la atención y la incidencia de complicaciones en desarrollo habitual de las labores del médico han sido previamente estudiados, aunque con resultados poco concluyentes. Objetivo: Comparar la incidencia de complicaciones, durante la punción, en el curso del bloqueo, como consecuencia de una analgesia incompleta y evaluar las diferencias que existen entre el día y la noche definiendo día como el periodo entre 9:00 y 21:59 h y noche: de 22:00 a 8:59 h. Material y métodos: Hemos realizado un estudio de los bloqueos recogidos en nuestra base de datos informatizada de pacientes a quienes se practicó algún bloqueo central para analgesia del parto realizados en un hospital universitario de grado 4, con atención durante las 24 horas, durante un periodo de 2 meses. Resultados: Se ha estudiado un total de 1097 pacientes, homogéneas en su distribución (variables demográficas y obstétricas, entre el día y la noche. El número de pacientes a las que se les practica un bloqueo analgésico para trabajo de parto no muestra diferencias entre el día y la noche. No hemos encontrado diferencias en la incidencia de complicaciones en la punción ni de analgesia incompleta, deficiente o necesidad de re-punción. Conclusiones: Parece que el cansancio o la falta de sueño no influyen en la incidencia de complicaciones en la analgesia para el trabajo de parto en una unidad de atención las 24 horas. Probablemente, los médicos se ven incentivados por la realización de una tarea interesante.Introduction: Sleep deprivation effects in vigilance, performance and complications have been previously studied in general population and in medical tasks too.

    Full Text Available La isquemia arterial periférica puede ser el resultado de diversas enfermedades que afectan la vascularización de los miembros, generando dolor, discapacidad y deterioro de la calidad de vida del paciente, y en los casos de isquemia crítica produciendo una considerable morbimortalidad y dolor crónico. El objetivo ha sido realizar una revisión histórica de publicaciones científicas acerca de los distintos tipos de isquemia periférica, del dolor derivado, de su tratamiento analgésico por vía epidural y de las peculiaridades que hay que tener en cuenta en dicha patología. Se ha realizado una búsqueda en MEDLINE y se han recopilado los principales datos respecto a la evolución y las principales líneas de investigación científicas publicadas en las áreas de la analgesia epidural y el dolor en el contexto de la isquemia arterial periférica. Desde su introducción terapéutica en la isquemia periférica, la analgesia con perfusión de fármacos epidurales ha constituido un método eficaz analgésico, que en el caso de los anestésicos locales, además, aporta efectos hemorreológicos positivos a través de un bloqueo simpático. La neuroestimulación eléctrica epidural (NEE medular es una modalidad analgésica crónica con indicaciones específicas dentro de la isquemia periférica, con potencial efecto trófico y capacidad de preservación de miembros, incluso en isquemia crítica aterooclusiva. El efecto, tanto analgésico como trófico de las distintas modalidades analgésicas epidurales, varía según sus características técnicas y según los distintos tipos de isquemia periférica. Se deben tener en cuenta las limitaciones y riesgos del tratamiento analgésico epidural en la isquemia de miembros. Se necesitan estudios científicos que evalúen la eficiencia y la efectividad de la NEE en la isquemia periférica de naturaleza no aterooclusiva, así como la investigación de parámetros clínicos vasculares que puedan actuar como

    implante de lente intra-ocular.JUSTIFICATIVA Y OBJETIVOS: En las intervenciones quirúrgicas para oftalmología no se encontró técnica de anestesia totalmente segura, la introducción de la anestesia extraconal hizo que aumentasen las indicaciones de cirugías oculares con bloqueo, ya que la incidencia de complicaciones graves es menor, un hecho ya descrito por Hay, en 1991. Los bloqueos extraconales pueden ser realizados por varias vías de acceso, entre ellas, la superior y la inferior. El objetivo de este estudio fue evaluar cual vía de acceso (superior o inferior promueve bloqueo anestésico de mejor calidad. MÉTODO: Fueron incluidos en este estudio 164 pacientes, de ambos sexos, con edades entre 23 y 92 años, estado físico ASA I a IV, índice cardíaco 1 y 2 de Goldman, con indicación de facectomia con implantación de lente intra-ocular. Los pacientes fueron distribuidos aleatoriamente en dos grupos de 82 de acuerdo con la vía de acceso primaria del bloqueo extraconal: grupo ES (extraconal superior y EI (extraconal inferior. La calidad del bloqueo fue evaluada por el aparecimiento de dolor en el per-operatorio, manutención de movimentación de las pálpebras o del globo ocular, persistencia del reflejo de Bell, número de bloqueos realizados para la obtención de condiciones quirúrgicas y evaluación del bloqueo por el cirujano. RESULTADOS: La vía de acceso superior presentó mayor incidencia de acinesis de pálpebras (Vía superior - 56,1%; vía inferior - 36,6% del músculo recto superior (vía superior 93,9%; vía inferior 65,9%, así como menor necesidad de bloqueos complementares (vía superior 29,3%; vía inferior 42,7%. La vía de acceso inferior presentó mayor acinesis del músculo recto inferior (vía superior 72%; vía inferior - 84,1% sin diferencia estadística. CONCLUSIONES: En las condiciones de este estudio, la vía extraconal superior demostró que es superior en relación a la vía extraconal inferior, como vía de acceso primaria para

    2004-11-01

    Full Text Available Introducción: El hematoma epidural secundario a una anestesia neuroaxial es una complicación poco frecuente, pero de gran trascendencia tanto por sus implicaciones clínicas como por las médico legales; según algunos autores su incidencia puede oscilar entre 1/190.000-1/200.000 para las punciones peridurales y 1/320.000 en el caso de las espinales. El aspecto prioritario en su manejo terapéutico es el del diagnóstico y tratamiento precoz, antes de las 6-12 primeras horas. No obstante, en determinados pacientes como en el caso que presentamos puede no ser precisa la cirugía, resolviéndose el cuadro con tratamiento conservador. Caso clínico: Varón de 73 años, ASA IV, con antecedentes de cirrosis con hipertensión portal, hiperesplenismo, EPOC, obesidad, cardiopatía hipertensiva e insuficiencia tricuspídea. Se programa para alcoholización prostática al haber sido desechada la cirugía. En la analítica preoperatoria destacaba una actividad de protrombina del 80% y 90.000 plaquetas. Se realizaron varios intentos fallidos de punción espinal, finalmente fue precisa una anestesia general con ventilación espontánea mediante mascarilla laríngea, propofol, fentanilo y sevoflurano. A las 36 horas, comienza la clínica en forma de dolor intenso lumbar, sin irradiación y arreflexia cutáneo plantar, confirmándose en la RMN la presencia de un hematoma epidural de L1 a L4. Ante la ausencia de paraparesia flácida, afectación esfinteriana u otros signos sensitivo-motores y tras consulta con la Unidad de Raquis y con el Servicio de Neurología se decide tratamiento conservador y actitud expectante en forma de analgesia y monitorización neurológica estricta, clínica y radiológica. Evolucionando favorablemente en los siguientes días. Discusión: Determinadas condiciones clínicas pueden influir en la aparición de un hematoma tras la realización de un bloqueo regional central: heparinas de bajo peso molecular, punciones dificultosas

    International Nuclear Information System (INIS)

    Central deposition of fat is a well-known clinical feature of long-term elevated corticosteroid levels. Rarely described is increased extadural fat within the spinal canal causing compression of the spinal cord and neurologic deficits. Together with 12 previously reported cases, the authors present six additional cases of epidural lipomatosis, review presenting signs and symptoms, and demonstrate the myelographic, CT, and MR findings in this condition. Previously undescribed examples of (1) normal myelography with diagnostic postmyelogram CT, (2) MR imaging of this condition, and (3) cases not associated with exogenous steroid use or morbid obesity are presented. The importance of considering this entity in the appropriate clinical setting is stressed. In particular, if clinical suspicion is high, even in the setting of a normal myelogram, CT or MR imaging should be considered

    consecuencias es la parálisis diafragmática. En pacientes con algún grado de disfunción pulmonar previa, esa parálisis puede conllevar a la insuficiencia respiratoria. El abordaje del plexo braquial por vía posterior ha conquistado espacio. El objetivo de este estudio fue el de determinar la prevalencia de parálisis diafragmática, después del bloqueo de plexo braquial interescalénico por vía posterior con el uso de ropivacaína a 0,2%. MÉTODO: Veinte y dos pacientes sometidos al bloqueo del plexo braquial interescalénico por vía posterior con ropivacaína a 0,2% fueron evaluados en el postoperatorio con el objetivo de identificar señales radiológicas de elevación de la cúpula diafragmática sugestivas de parálisis hemidiafragmática. En 20 pacientes se utilizó 40 mL de ropivacaína a 0,2%, en ellos fue realizada la radiografía de tórax en inspiración. En dos fueron utilizados 20 mL de ropivacaína a 0,2%, con la siguiente evaluación fluoroscópica. RESULTADOS: No hubo complicaciones relacionadas con la realización del bloqueo. En todos los pacientes, el bloqueo fue efectivo y proporcionó una buena analgesia postoperatoria. Se observó una elevación de la cúpula diafragmática compatible con la parálisis hemidiafragmática en todos los casos estudiados.

    Background: There are few reported cases of an epidural spinal hematoma following interventional pain procedures. Case Description: We report a case of a spinal epidural hematoma in a patient with no known risk factors (e.g. coagulopathy), who underwent an epidural steroid injection (ESI) in the same anatomic location as two previously successful ESI procedures. Conclusion: Early detection was the key to our case, and avoiding sedation allowed the patient to recognize the onset of a new neurological deficit, and lead to prompt diagnosis as well as surgical decompression of the resultant hematoma.

    Full Text Available El presente trabajo corresponde una revisión bibliográfica de los estudios clínicos realizados en síndromes anginosos refractarios al tratamiento convencional, utilizando como tratamiento el bloqueo de ganglio estrellado. Se realizó una búsqueda de literatura publicada entre los años 1.900 al 2.000 en las bases de datos MDConsult, Medline y ProQuest. A su vez se revisaron las publicaciones en la Biblioteca del Hospital Rafael Ángel Calderón Guardia y en la Biblioteca del BINASSS (Biblioteca Nacional de Salud del Seguro Social. De acuerdo a los estudios analizados el bloqueo de ganglio estrellado se describe como posibilidad terapéutica para el control de dolor de la angina de pecho refractaria . La descripción clásica de la inervación cardíaca consiste en tres nervios simpáticos mayores originados de los ganglios cervicales superior, medio e inferior. Esta inervación simpática en conjunto con diversos nervios parasimpáticos, se describen como el plexo cardíaco. En contraste Jane et. al. (1986 en un estudio anatómico de 23 cadáveres describe que la inervación cardiopulmonar en el hombre se origina en el ganglio estrellado y las mitades caudales de las cadenas simpáticas cervicales junto con nervios que se originan del nervio recurrente laríngeo o del vago. De estas estructuras derivan los dos plexos cardiopulmonares. De estos plexos derivan tres nervios cardíacos mayores que se proyectan hacia el corazón. Se estima que determinado porcentaje de los pacientes diagnosticados con angina inestable progresará a desarrollar una angina refractaria al tratamiento. El bloqueo de ganglio estrellado podría ser un nuevo método terapéutico para controlar el dolor de dicha condición. Sin embargo se necesitan estudios clínicos randomizados a doble ciego para obtener resultados concluyentes.

    Full Text Available Introducción: Los intentos repetidos de punción son factores de riesgo para la aparición de complicaciones neurológicas secundarias a la práctica de la analgesia espinal y aumentan la ansiedad del paciente. El objetivo de este estudio es determinar qué factores son mejores predictores de la colocación dificultosa del catéter epidural en la paciente obstétrica. Material y método: Estudio observacional y prospectivo en 120 gestantes a término que solicitan la analgesia epidural para el trabajo de parto. Se recogen variables demográficas y antecedentes de anestesia espinal previa no exitosa o considerada dificultosa por la paciente. Se identifican variables anatómicas y se clasifica la calidad de los puntos de referencia anatómicos según los criterios publicados por Chien en cuatro grados. Las condiciones de la técnica y la experiencia del anestesiólogo son similares en todos casos. Consideramos punción dificultosa si se necesita más de una punción en la piel o una punción pero más de un cambio de dirección de aguja en el espacio interespinoso. Se recoge el éxito obtenido y las complicaciones de la técnica. Resultados: Fueron calificadas de punción difícil según los criterios del estudio en el 36,67 % de los casos. En la mayoría de los casos la técnica fue efectiva obteniendo una adecuada analgesia. La incidencia de repunción epidural fue de 5 %. En las pacientes clasificadas en el grado 4, la tasa de punción epidural considerada dificultosa supuso un 90 %, necesitando en el 80 % de esos casos 3 o más intentos. En las pacientes con antecedentes personales de técnica neuroaxial dificultosa se encontró dificultad de punción epidural en un 28,57 % de los casos. El hábito corporal no tuvo efecto significativo sobre la tasa de éxito con el primer intento. Discusión: Nuestro estudio representa una buena estimación de la dificultad técnica de un bloqueo neuroaxial. Seria difícil saber si los datos reflejados ser

    Spinal epidural abscess is an uncommon entity, the frequency of which is increasing. They occur spontaneously or as a complication of intervention. The classical triad of fever, back pain and neurological symptoms are not always present. High index of suspicion is key to diagnosis. Any delay in diagnosis and treatment can have significant neurological consequences. We present the case of a previously well man with a one month history of back pain resulting from an epidural abscess.

    resulta en alta efectividad para el bloqueo axilar del plexo braquial. La técnica de utilizar múltiples estímulos exige más tiempo y mayor experiencia. Este estudio prospectivo compara la latencia y el índice de éxito del bloqueo del plexo braquial usando dos técnicas de localización: transarterial o múltipla estimulación de los nervios. MÉTODO: La lidocaína con epinefrina, 800 mg, fue usada inicialmente para el bloqueo axilar. En el grupo transarterial, 30 mL de lidocaína a 1,6% con epinefrina fueron inyectados profundamente y 20 mL superficialmente a la arteria axilar. En el grupo de múltipla estimulación, tres nervios fueron localizados eléctricamente y bloqueados con volúmenes 20 mL, 20 mL y 10 mL de la solución. El bloqueo fue considerado efectivo cuando la analgesia estaba presente en todos los nervios en la área distal al codo. RESULTADOS: El tiempo de latencia (8,8 ± 2,3 min versus 10,2 ± 2,4 min; p-valor = 0,010 fue significativamente menor en el grupo transarterial. Bloqueos sensitivos completos en los cuatro nervios (mediano, ulnar, radial y musculocutáneo fueron logrados en un 92,5% versus 83,3% en el grupo de múltipla estimulación y acceso transarterial, respectivamente sin diferencia significativa (p-valor = 0,68. El nervio musculocutáneo fue significativamente más fácil de bloquear con el estimulador de nervio periférico (p = 0,034. CONCLUSIONES: La técnica de múltipla estimulación para el bloqueo axilar usando estimulador de nervios (3 inyecciones y la técnica transarterial (2 inyecciones producen resultados semejantes en la calidad del bloqueo. El nervio musculocutáneo es más facilmente bloqueado con el uso del estimulador del nervio periférico. La técnica de múltipla estimulación necesitó menor suplementación del bloqueo y aumentó el tiempo para el inicio de la cirugía.BACKGROUND AND OBJECTIVES: High-dose transarterial technique results in highly effective axillary block.

Primary spinal epidural lymphoma (PSEL is a subset of lymphomas, where there are no other recognizable sites of lymphomas at the time of diagnosis. The incidence of this subset of lymphomas is much less. It, however, is increasingly diagnosed, due to the increased use of more sensitive imaging modalities. For the electronic search, Pubmed was used to identify journals that enlisted and enumerated PSEL from 1961 to January 2011. The following combination of terms: "primary," "spinal," "epidural," and "lymphoma" were used. The most significant articles and their bibliographies were analyzed by the authors. The symptoms, pathogenesis, diagnostic workup, histopathology, treatment, and outcome have been analyzed in a systematic manner

CONCLUSIONES: El rápido diagnóstico con intervención quirúrgica precoz es el tratamiento más eficaz para la reducción de la lesión neurológica, en pacientes que desarrollan hematoma peridural postoperatorio. La utilización de heparina de bajo peso molecular, con uso actual de catéter peridural, exige la adhesión estricta a protocolos establecidos, para que se reduzcan los riesgos del desarrollo de hematoma peridural.BACKGROUND AND OBJECTIVES: Presents a patient case with epidural hematoma, in the course of the use of epidural catheter and low molecular weight heparin, her clinical condition and treatment. CASE REPORT: A 75-year old female patient, submitted to the fixation of lumbar spine by anterior route, who, in the postoperative period, developed a clinical condition of progressive paralysis of the lower limbs, with loss of sensitivity and presenting no intense radicular pain. The treatment was the immediate medullar decompression, with drainage and surgical cleaning of a epidural hematoma, which extended from the 5th to the 10th thoracic vertebrae. After the drainage of the hematoma, the patient gradually recovered the strength in the lower limbs, was discharged in ten days with a condition of sphincterian dysfunction. After three months, the condition receded and there was no definitive neurological sequel. CONCLUSIONS: The quick diagnosis with early surgical intervention is the most effective treatment for the reduction of neurological damage, in patients that develop postoperative epidural hematoma. The use of low molecular weight heparin, in the course of the use of epidural catheter, requires the strict compliance with the established protocols so that the risks of epidural hematoma development can be

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.

    anestesiologista conhecimento minucioso da anatomia, treinamento na técnica e vigilância constante.JUSTIFICATIVA Y OBJETIVOS: El bloqueo del plexo lumbar puede ser bastante útil en procedimientos quirúrgicos de la cadera, del muslo y de la rodilla, pero exige práctica del anestesiólogo teniendo en cuenta sus potenciales complicaciones. El presente relato tiene como objetivos presentar un caso de raquianestesia total después del bloqueo del plexo lumbar por la vía posterior y discutir el probable mecanismo fisiopatológico. RELATO DEL CASO: Paciente del sexo masculino, 34 años, 97 kg, estado físico ASA I, programado para artroplastia total de la cadera. Fue realizada anestesia general seguida de bloqueo del plexo lumbar derecho por la vía posterior con auxilio de estimulador de nervio periférico. La aguja fue introducida hasta una profundidad de 8 cm, perpendicular a la piel, y a una distancia de 4 cm de la línea media sobre una línea perpendicular al proceso espinoso de L4. Después de la identificación de respuesta motora en el cuadriceps, la intensidad de la corriente de estimulación se redujo hasta 0,35 mA, siendo entonces administrada ropivacaína a 0,5% (39 mL. Durante la inyección, fueron verificadas contracciones intermitentes del cuadriceps. Después del bloqueo, el paciente evolucionó con apnea, hipotensión arterial y midriasis bilateral. Al final de la cirugía, presentaba bloqueo motor en los dos miembros inferiores que solo mejoró nueve horas después de la realización del bloqueo. En el postoperatorio, el paciente se quejó de dolor intenso, recibiendo alta hospitalaria 12 días después de la cirugía sin anormalidades motora o sensitiva. CONCLUSIONES: La identificación del compartimento del psoas, donde está el plexo lumbar, exige la utilización de intensidad de corriente entre 0,5 e 1 mA. La incidencia de respuesta motora con bajas corrientes puede indicar posicionamiento de la aguja dentro del recubrimiento que envuelve la raíz nerviosa y

    Full Text Available Introducción: el dolor crónico es una entidad que afecta a la salud física y psicológica de los pacientes. El síndrome postlaminectomía consiste en la aparición o persistencia de dolor lumbar y/o radicular en un paciente que ha tenido uno o más procedimientos quirúrgicos en la columna. Objetivo general: evaluar la efectividad de la administración de ozono epidural y paravertebral, a una concentración de 50 μg/ml, en pacientes con dolor crónico asociado a síndrome postlaminectomía lumbar. Material y métodos: durante el periodo comprendido entre el 15 de julio y el 30 de diciembre del 2010 se realizó un estudio prospectivo, en 30 pacientes de ambos géneros, con edades comprendidas entre los 18 y los 85 años de edad, que tenían un diagnóstico de dolor crónico secundario a síndrome postlaminectomia lumbar. La media de las EVAs iniciales fue 6,8 sobre 10. La primera infiltración se realizó bajo sedación endovenosa y con control fluoroscópico de la región lumbosacra; se administró vía caudal un volumen de 20 ml de ozono a una concentración de 50 μg/ml en el espacio epidural, y en la región muscular paravertebral lumbar bilateral (L3, L4 y L5 se administraron 10 ml de ozono a la misma concentración en cada nivel. En total, el volumen infiltrado fue de 60 ml. La infiltración en la región paravertebral se repitió, al mismo volumen y concentración, en intervalos de 7 días durante 3 semanas consecutivas. Para medir la efectividad del tratamiento se evaluó la intensidad del dolor considerando las medias inicial y final en la escala visual analógica (EVA. Como medida de la funcionalidad se usó el índice de discapacidad de Oswestry, que se registró previo a la infiltración y a las semanas 4 y 8. El análisis estadístico se realizó mediante el programa Statistical 7.0, aplicando el test de Friedman para las dos variables principales, y la estadística descriptiva (media y desviación estándar para el an

    Epidural infusion of local analgesic and opioid are commonly used for postoperative pain relief. This combina-tion gives excellent anlgesia but nausea and vomiting remains a major concern. Low dose epidural naloxone prevents PONV induced by spinal opioids like morphine, fentanyl and sufentanil. However, it is not known that epidural naloxone administration prevents PONV induced by epidural buprenorphine. We have reported three cases of major abdominal operation in which lowdose epidural infus...

    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.

    A unique case of idiopathic diffuse lipomatosis is reported. The patient was an 11-year-old boy with diffuse lipomatosis in the epidural space, paraspinal muscles, and thoracolumbar subcutaneous regions. Epidural lipomatosis involved the entire thoracolumbar spine and was associated with filar thickening and lipoma. In addition, paraspinal muscles, especially the erector spinae group, had diffuse fatty infiltration. The ultimate clinical effect of this fatty tissue was urinary dysfunction, radicular pain and hypoesthesia in both legs and difficulty walking. (orig.)

    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.

La incidencia de efectos adversos fue semejante entre los grupos. CONCLUSIONES: La mezcla enantiomérica de bupivacaína (S75-R25 presentó mayor tiempo analgésico y menor grado de bloqueo motor, comparada con la solución de bupivacaína racémicaBACKGROUND AND OBJECTIVES: A bupivacaine formulation containing 25% of R(+ and 75% of S(- isomer has been used because its anesthetic properties with less toxicity than the racemic bupivacaine. This study aimed at evaluating the racemic bupivacaine as compared to B25/75 in epidural anesthesia. METHODS: Participated in this study 44 patients who were distributed in two groups (n = 22, namely Bupivacaine and S75-R25. Patients were premedicated with intravenous midazolam. Epidural anesthesia was induced at L3-L4 or L2-L3 interspace with 16 to 24 ml of the anesthetic solution. Group Bupivacaine received 0.5% bupivacaine with vasoconstrictor. Group S75-R25 received the enantiomeric mixture of 0.5% bupivacaine with vasoconstrictor. The following parameters were evaluated: lower limb temperature before and after epidural block, blockade onset, type of sensation referred by the patient, possible sensory failures, metameric sensory level and motor block level. Time for first analgesic request in the PACU was also recorded. RESULTS: Forty-one patients completed the study. Groups were demographically similar. Perioperative midazolam dose, epidural anesthetic volume, blockade onset, sensory failures at pinprick, lower limb temperature in different moments, type of paresthesia sensation and anesthetic depth in dermatomes were similar between groups. Motor block was less intense in group S75-R25 (p = 0.0117 as compared to group Bupivacaine.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: A cirurgia de artroplastia vertebral com uso do cimento ósseo tem suas particularidades e complicações. Na maioria das vezes o procedimento é realizado sob anestesia local com sedação, mas algumas vezes é realizado bloqueio subaracnóideo ou peridural com morfina com o intuito de fornecer analgesia pós-operatória. O objetivo deste relato foi discutir as possíveis complicações em cirurgias de artroplastia vertebral. RELATO DO CASO: Paciente do sexo masculino, 76 anos, apresentando fratura patológica em T12, foi admitido para cirurgia de artroplastia vertebral e biopsia óssea. Foi realizada sedação com midazolam e fentanil, o paciente foi colocado em decúbito ventral e o cirurgião infiltrou anestésico local desde a pele até o corpo vertebral de T12 a seguir biopsiou a vértebra e injetou 6 mL de cimento ósseo em T12. Ao final do procedimento o paciente apresentava paralisia dos membros inferiores. CONCLUSÕES: A intervenção cirúrgica na coluna vertebral não é procedimento isento de complicações. Quando se associa bloqueio espinal pode-se retardar o diagnóstico de complicação cirúrgica; além disto corre-se o risco de se imputar à anestesia um problema proveniente do procedimento cirúrgico.JUSTIFICATIVA Y OBJETIVOS: A cirugía de artroplastia vertebral con uso del cimiento óseo tiene sus particularidades y complicaciones.

  7. MR imaging of spinal epidural sepsis

    International Nuclear Information System (INIS)

    Spinal epidural abscess is uncommonly found in adults and children. Early diagnosis and treatment improves prognosis and prevents serious neurologic sequelae. Four patients with spinal epidural infections were recently evaluated with MR and CT of the spine. In all cases, MR and CT localized the site of infection accurately and showed adjacent bony osteomyelitis. MR proved superior in characterizing infection (abscess vs. inflammatory edema) and demonstrating epidural involvement and spinal cord compression. In all cases, MR obviated the need for myelography. Early recognition by MR of spinal epidural sepsis led to expeditious treatment and better clinical outcome

    The spinal canal takes the form of a series of cylinders designated by their relationship to the meninges and is divided by the dura mater into the epidural or extradural space and intradural space. The epidural space is composed of spinal ligaments, connective and areolar tissue, the epidural venous plexus, lymphatic channels and supporting elements, and various pathologic entities are found there. MR imaging can accurately depict the extent and characteristics of lesions, and in some cases specific diagnosis is possible. In this pictorial essay, we illustrate a variety of spinal epidural lesions and their MR findings.

    A 48-year-old man presented to the emergency department with complain of severe neck pain and anterior chest pain. Intermittent fever in the recent 2 days was also noted. There is a track maker over his left side of neck. The laboratory examination showed leukocytosis and high C-reactive protein level. Urine drug screen was positive for opiate. Empirical antibiotic administration was given. Blood culture grew gram-positive cocci in chain, and there was no vegetation found by heart echocardiogram. However, progressive weakness of four limbs was noted, and patient even cannot stand up and walk. The patient also complained of numbness sensation over bilateral hands and legs, and lower abdomen. Acute urine retention occurred. We arranged magnetic resonance imaging survey, which showed evidence of inflammatory process involving the retropharyngeal spaces and epidural spaces from the skull base to the bony level of T5. Epidural inflammatory process resulted in compression of the spinal cord and bilateral neural foramen narrowing. Neurosurgeon was consulted. Operation with laminectomy and posterior fusion with bone graft and internal fixation was done. Culture of epidural abscess and 2 sets of blood culture all yielded methicillin-sensitive Staphylococcus aureus. For epidural abscess, the most common involved spine is lumbar followed by thoracic and cervical spine. Diagnosis and treatment in the drug abusers are still challenging because they lack typical presentation, drug compliance, and adequate follow-up and because it is hard to stop drug abuser habit. Significant improvement of neurological deficit can be expected in most spinal abscess in drug abusers after treatment. PMID:26298050

    International Nuclear Information System (INIS)

    To measure the clinically relevant skin to posterior lumbar epidural space distance in adult surgical patients and to correlate this distance with the patient physical factors to construct a model for the prediction of this distance using the correlation. The study was carried out in 100 patients divided into three groups, who were scheduled for different surgical procedures. Group-I consisted of female patients scheduled for lower segment caesarian section (L.S.C.S); group-II adult non-pregnant females undergoing elective surgery and group-III adult males undergoing different surgical procedures. Epidural anaesthesia was given, using loss of resistance (LOR) technique, and skin to posterior epidural space was measured. The mean skin to posterior lumbar epidural space distance was found to be 3.8 +- 0.5 cm in group-I, 3.76 +- 0.7 cm in group- II and 4.0 +- 0.5 cm in group-III. Skin to posterior epidural space distance correlates best with weight of the patient. Posterior lumbar skin to epidural space distance has been found to be less than what is normal in rest of the world. These results may be used as a guideline for performing successful epidural blocks in Pakistani population. A reliable model using patient physical factors to predict skin to posterior epidural space distance could not be constructed. (author)

    International Nuclear Information System (INIS)

    Extensive, diffuse, epidural spinal cord compression was visualized myelographically in two dogs presented for rapid development of nonambulatory tetraparesis and paraplegia, respectively. Purulent fluid containing bacterial organisms was aspirated percutaneously under fluoroscopic guidance from the epidural space of each dog. One dog responded poorly to aggressive medical therapy, which included installation of an epidural lavage and drainage system. Both dogs were euthanized due to the severe nature of their disorder and the poor prognosis. Spinal epidural empyema (i.e., abscess) is a rare condition in humans and has not been reported previously in the veterinary literature. Spinal epidural empyema should be considered as a differential diagnosis in dogs presenting with painful myelopathies, especially when accompanied by fever

    Full Text Available La incidencia de lesiones neurológicas de miembros inferiores en la práctica obstétrica es del 0,08% y 0,92%. La incidencia de complicaciones neurológicas asociadas a la técnica epidural ha sido estimada en 2 casos de cada 10.000 epidurales. Durante los últimos años, con la generalización de la analgesia epidural para el trabajo de parto, es posible que algunas de las neuropatías sean atribuidas a esta técnica, olvidando que hay otros mecanismos de lesión en estas situaciones. Presentamos el caso de una paciente primigesta de 21 años de edad y 139 cm de altura sin antecedentes de interés, que 24 horas tras una epidural para parto y un expulsivo prolongado resuelto con fórceps, desarrolla un "pie caído", que evolucionó a la resolución funcional completa. El pie caído puede darse como consecuencia de una lesión del nervio peroneo, del ciático, o de una raíz del plexo lumbo-sacro. La clínica unida al uso de pruebas como la resonancia magnética (RNM y el electromiograma (EMG, ayudan en el diagnóstico diferencial de la lesión. Parece necesario el estudio del las neuropatías relacionadas con el parto para descartar su relación con la técnica anestésica empleada. Con frecuencia, estas lesiones se deben a mecanismos ajenos a la analgesia-anestesia epidural, si bien debemos procurar minimizar su incidencia con la realización de punciones a niveles adecuados, evitando la inyección de anestésicos cuando existen parestesias, valorando los factores de riesgo en obstetricia y, una vez producida la lesión, con un seguimiento clínico estrecho.Postpartum neurological damage occurs in the obstetric practice with an incidence between 0.08-0.92%.

The magnetic resonance imaging showed an extramedullary, extradural space occupative lesion on the right side of the spinal canal from D5 to D7 vertebral levels. The mass was well marginated and there was no bone involvement. Compression of the adjacent thecal sac was observed, with displacement to the left side. Radiological differential diagnosis included nerve sheath tumor and meningioma. The patient underwent D6 hemilaminectomy under general anesthesia. Intraoperatively, the tumor was purely extradural in location with mild extension into the right foramina. No attachment to the nerves or dura was found. Total excision of the extradural compressing mass was possible as there were preserved planes all around. Histopathology revealed cavernous hemangioma. As illustrated in our case, purely epidural hemangiomas, although uncommon, ought to be considered in the differential diagnosis of spinal epidural soft tissue masses. Findings that may help to differentiate this lesion from the ubiquitous disk prolapse, more common meningiomas and nerve sheath tumors are its ovoid shape, uniform T2 hyperintense signal and lack of anatomic connection with the neighboring intervertebral disk or the exiting nerve root. Entirely extradural lesions with no bone involvement are rare and represent about 12% of all intraspinal hemangiomas.

    Spinal epidural lipomatosis (SEL) is a rare but well-recognized condition. In general, the onset of its symptoms is insidious and the disease progresses slowly. We report two cases of rapid progression of SEL with no history of steroid intake in non-obese individuals after epidural steroid injection. These SEL patients developed neurologic symptoms after less than 5 months; these symptoms were confirmed to be due to SEL by serial MR images. After the debulking of the epidural fat, their sympt...

    Epidural steroid injections (ESI) are a common treatment for back pain management. ESI-related complications have increased with the growing number of procedures. We report a case of cervical meningomyelitis followed by multiple lumbar ESI. A 60-year-old male with diabetes mellitus presented to our hospital with severe neck pain. He had a history of multiple lumbar injections from a local pain clinic. After admission, high fever and elevated inflammatory values were detected. L-spine magnetic resonance imaging (MRI) revealed hematoma in the S1 epidural space. Antibiotic treatment began under the diagnosis of a lumbar epidural abscess. Despite the treatment, he started to complain of weakness in both lower extremities. Three days later, the weakness progressed to both upper extremities. C-spine MRI revealed cervical leptomeningeal enhancement in the medulla oblongata and cervical spinal cord. Removal of the epidural abscess was performed, but there was no neurological improvement.

    In 1901, the first Epidural anesthesia via a caudal approach was independently described by two FrenchmanJean-Anthanase Sicard and Fernand Cathelin.. The Spanish military surgeon, Fidel Pagés Miravé, completed the lumbar approach successfully in 1921. The two possibilities for identification of the epidural space the "loss of resistance" technique and the technique of the "hanging drop" were developed by Achille Mario Dogliotti, an Italian, and Alberto Gutierrez, an Argentinean physician, at the same time. In 1956 John J. Bonica published the paramedian approach to the epidural space. As early as 1931 Eugene Aburel, a Romanian obstetrician, injected local anaesthetics via a silk catheter to perform lumbar obstetric Epidural analgesia. In 1949 the first successful continuous lumbar Epidural anaesthesia was reported by Manuel Martinez Curbelo, a Cuban. Epidural anaesthesia can be performed in sitting or lateral position in all segments of the spinal column via the median or paramedian approach. Different off-axis angles pose the challenge in learning the technique. PMID:26230893

    Full Text Available En este artículo se describen desde una perspectiva comparativa los fenómenos de bloqueo, ensombrecimiento e inhibición latente, enfatizando su presencia en tareas de aprendizaje espacial. Estos fenómenos de aprendizaje, ampliamente observados en otras clases de vertebrados e invertebrados, han sido recientemente descriptos por primera vez en anfibios, un grupo de vertebrados con un cerebro filogenéticamente antiguo. Tomando como modelo al sapo terrestre Rhinella arenarum, se revisarán los tres fenómenos de aprendizaje asociativo mencionados en una situación de aprendizaje espacial: (1 bloqueo entre claves visuales asociadas a una meta, (2 ensombrecimiento de una clave visual lejana por la presencia de una clave cercana y (3 inhibición latente debida a la pre-exposición a una cla ve visual. Todos los entrenamientos se llevaron a cabo en una arena circular de color blanco, utilizando agua como recompensa. Dentro de la arena, se distribuyeron cuatro piletas de acrílico en forma de cruz contra las paredes laterales (sólo una tenía acceso a la recompensa. En las paredes interiores de la arena circular se colocaron varias señales visuales para guiar a los animales. Los resultados obtenidos en sapos indican que estos fenómenos, observados previamente en aves y mamíferos, también se encuentran en este grupo (uti lizando un paradigma de aprendizaje espacial con claves visuales cercanas y lejanas. Este primer registro en anfibios sugiere que los mecanismos biológicos de estos fenómenos de aprendizaje han surgido muy tempranamente en el curso de la evolución de los vertebrados totalmente terrestres y que los mismos han sido fuertemente conservados. El análisis comparado de estos hallazgos contribuirá a mejorar el entendimiento de los mecanismos biológicos que subyacen al aprendizaje espacial, en busca de patrones funcionales comunes con otras clases de vertebrados y potencialmente presentes en un ancestro común.

    Full Text Available La anestesia locorregional es uno de los mejores métodos para el control y manejo del dolor intra y postoperatorio. En el paciente pediátrico este tipo de analgesia normalmente se realiza junto con anestesia general o sedación profunda, por la escasa o nula colaboración de los niños. Para la cirugía de hombro y antebrazo uno de los bloqueos periféricos más eficaces es el del plexo braquial por abordaje interescalénico, considerando siempre su elevada incidencia de complicaciones como la parálisis frénica ipsolateral, entre otras. Presentamos el caso de un niño de 13 años de edad propuesto para injerto de húmero de cadáver en miembro superior derecho. Un año antes se realizó resección de tumor refiriéndose un mal manejo del dolor postoperatorio con mórficos en PCA. Como técnica anestésica se realizó una anestesia general y, posteriormente, un bloqueo del plexo braquial por vía interescalénica con ecografía y neuroestimulador, y posterior colocación de catéter para analgesia en el postoperatorio. Se administraron 10 ml de levobupivacaína al 0,5%, sin necesidad de más analgésicos suplementares durante las 6 h que duró la intervención quirúrgica. Al finalizar la cirugía el paciente fue extubado en quirófano objetivando ausencia de dolor, síndrome de Horner y parálisis diafragmática izquierda sin repercusión clínica. Durante las 24 h siguientes se administraron 10 ml/h de ropivacaína al 0,25% a través del catéter, y así se consiguió una analgesia excelente y sin necesidad de bolos a demanda de anestésico local. En conclusión, la anestesia locorregional aporta una adecuada analgesia peri y postoperatoria, disminuyendo la necesidad de analgésicos adyuvantes. La utilización de la ecografía en la realización del bloqueo interescalénico permite no sólo una disminución de las dosis necesarias de anestésico local, sino también una visualización directa en la zona de administración, por lo que podr

  17. Symptomatic Spinal Epidural Lipomatosis After a Single Local Epidural Steroid Injection

    International Nuclear Information System (INIS)

    Spinal epidural lipomatosis is a rare disorder that can manifest with progressive neurological deficits. It is characterized by abnormal accumulation of unencapsulated epidural fat commonly associated with the administration of exogenous steroids associated with a variety of systemic diseases, endocrinopathies, and Cushing syndrome (Fogel et al. Spine J 5:202–211, 2005). Occasionally, spinal epidural lipomatosis may occur in patients not exposed to steroids or in patients with endocrinopathies, primarily in obese individuals (Fogel et al. Spine J 5:202–211, 2005). However, spinal lumbar epidural lipomatosis resulting from local steroid injection has rarely been reported. We report the case of a 45-year-old diabetic man with claudication that was probably due to symptomatic lumbar spinal lipomatosis resulting from a single local epidural steroid injection.

    Lumbosacral epidural lipomatosis (LEL) is characterized by excessive deposition of epidural fat (EF). The purpose of our retrospective study was to quantify normal and pathologic amounts of EF in order to develop a reproducible MRI grading of LEL. In this study of 2528 patients (1095 men and 1433 women; age range 18-84 years, mean age 47.3 years) we performed a retrospective analysis of MRI exams. We obtained four linear measurements at the axial plane parallel and tangent to the superior end plate of S1 vertebral body: antero-posterior diameter of dural sac (A-Pd DuS), A-Pd of EF, located ventrally and dorsally to the DuS, and A-Pd of the spinal canal (Spi C). We calculated (a) DuS/EF index and (b) EF/Spi C index. We developed the following MRI grading of LEL: normal, grade 0: DuS/EF index {>=}1.5, EF/Spi C index {<=}40%; LEL grade I: DuS/EF index 1.49-1, EF/Spi C index 41-50% (mild EF overgrowth); LEL grade II: DuS/EF index 0.99-0.34, EF/Spi C index 51-74% (moderate EF overgrowth); LEL grade III: DuS/EF index {<=}0.33, EF/Spi C index {>=}75% (severe EF overgrowth). The MRI exams were evaluated independently by three readers. Intra- and interobserver reliabilities were obtained by calculating Kappa statistics. The MRI grading showed the following distribution: grade 0, 2003 patients (79.2%); LEL grade I, 308 patients (12.2%); LEL grade II, 165 patients (6.5%); and LEL grade III, 52 patients (2.1%). The kappa coefficients for intra- and interobserver agreement in a four-grade classification system were substantial to excellent: intraobserver, kappa range 0.79 [95% confidence interval (CI), 0.65-0.93] to 0.82 (95% CI, 0.70-0.95); interobserver, kappa range 0.76 (95% CI, 0.62-0.91) to 0.85 (95% CI, 0.73-0.97). In LEL grade I, there were no symptomatic cases due to fat hypertrophy. LEL grade II was symptomatic in only 24 cases (14.5%). In LEL grade III, all cases were symptomatic. A subgroup of 22 patients (42.3%) showed other substantial spinal pathologies (e

    To evaluate the radiologic findings of intraspinal epidural arachnoid cyst. Six patients with surgically proven intraspinal epidural arachnoid cyst were included in this study. Four were free of specific past history, but two had a history of trauma. All underwent examination by plain radiogr4aphy, CT-myelography and MRI, and the following aspects were retrospectively analysed:vertebral pressure erosion, interpedicular distance, enlargement of neural foramina, as seen on plain radiograph, contrast-filling and lateral bulging of lesions through neural foramina on CT-myelograph, and signal intensity, size and shape of margin and epidural fat pattern, as seen on MRI. Three of four congenital intraspinal epidural arachnoid cysts were single in the thoracolumbar region, while in the other case, there were multiple cysts in the mid-and lower thoracic regions. Cysts were equivaleut in size to between four and six vertebral bodies. Plain radiographic findings of pedicular pressure erosion, widened interpedicular distance, and bilateral neural foraminal enlargement of several contiguous vertebrae were observed in all four cases. One showed posterior vertebral scalloping. On CT-myelograph, a contrast-filled cystic lesion occupying the posterior epidural space, with lateral bulging through neural foramina and anterior displacement of the contrast-filled thecal sac, was seen. On MRI, longitudinally elongated, well-demarcated cysts were seen to be present in the posterior epidural space;their signal intensity was the same as in CSF.

    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. The literature and our clinical experience have been reports linking neonatal respiratory depression with increasing temperature (37

    Lumbar radiculopathy is generally caused by such well-recognized entity as lumbar disc herniation in neurosurgical practice; however rare pathologies such as thrombosed epidural varix may mimic them by causing radicular symptoms. In this case report, we present a 26-year-old man with the complaint of back and right leg pain who was operated for right L4-5 disc herniation. The lesion interpreted as an extruded disc herniation preoperatively was found to be a thrombosed epidural varix compressing the nerve root preoperatively. The nerve root was decompressed by shrinking the lesion with bipolar thermocoagulation and excision. The patient's complaints disappeared in the postoperative period. Thrombosed lumbar epidural varices may mimic lumbar disc herniations both radiologically and clinically. Therefore, must be kept in mind in the differential diagnosis of lumbar disc herniations. Microsurgical techniques are mandatory for the treatment of these pathologies and decompression with thermocoagulation and excision is an efficient method. PMID:27446525

    Full Text Available An 8-month-old male infant had presented with a history of a fall from the crib a fortnight ago. He had developed progressive weakness of both lower limbs. On examination, the infant had spastic paraplegia. Magnetic resonance (MR imaging of the cervical spine showed an epidural hematoma extending from the fourth cervical (C4 to the first dorsal (D1 vertebral level with cord compression. The patient had no bleeding disorder on investigation. He underwent cervical laminoplasty at C6 and C7 levels. The epidural hematoma was evacuated. The cervical cord started pulsating immediately. Postoperatively, the patient′s paraplegia improved dramatically in 48 hours. According to the author′s literature search, only seven cases of post-traumatic epidural hematoma have been reported in pediatric patients, and our patient is the youngest. The present case report discusses the etiopathology, presentation, and management of this rare case.

    Full Text Available Background. Traumatic delayed epidural hematoma (DEH can be defined as insignificant or not seen on the initial CT scan performed after a trauma but seen on the subsequent CT scan as a “massive” epidural bleeding. Case report. We presented two cases of traumatic DEH after mild head injury. Both patients were conscious and without neurological deficit on the admission. Initial CT scan did not reveal intracranial hematoma. Repeated CT scan, that was performed after neurological deterioration, revealed epidural hematoma in both cases. The patients were operated with a favorable surgical outcome. Conclusion. Traumatic DEH could occur in the patients with head injuries who were conscious on the admission with a normal initial CT scan finding. Early detection of DEH and an urgent surgical evacuation were essential for a good outcome.

    Pain caused by tumor infiltration of the sacral area remains a major clinical challenge. Patients with poor pain control despite comprehensive medical management may be treated with neuraxial techniques such as continuous epidural or spinal anesthetic. We report a case in which a patient with metastatic breast cancer experienced inadequate pain relief after multiple intravenous pain management regimens as well as intrathecal (IT) drug delivery. The concentration of local anesthetics delivered via the IT catheter was limited due to the patient's baseline motor weakness which would be exacerbated with higher concentrations of local anesthetics. Thus, a decision was made to insert an epidural catheter via a retrograde technique to provide the patient with a "band of anesthesia" which would provide profound sensory blockade without concomitant motor weakness. Pain refractory to other modalities of pain control was successfully treated with the epidural technique. PMID:27162431

    Epidural angiolipomas are uncommon benign tumors of the spine. Their clinical presentation is usually a progressive spinal cord compression. We report the case of a 22-year-old patient who presented with an acute paraparesis and a spontaneous epidural hematoma, which revealed a epidural angiolipoma which extended from C7 to T3. The patient underwent a C7-T3 laminectomy, in emergency, with evacuation of the hematoma and extradural complete resection of a fibrous epidural tumor bleeding. The postoperative course was favorable with regression of neurological symptoms. Epidural angiolipomas can be revealed by spontaneous intratumoral hemorrhage without traumatism. The standard treatment is total removal by surgery. PMID:26597606

Material y métodos: Estudio retrospectivo y observacional que incluyó a todas las mujeres que dieron a luz en el Complejo Hospitalario de Segovia durante un periodo de 8 meses. La analgesia epidural obstétrica, cuando se administró, consistió en una perfusión de bupivacaína al 0,125% más fentanilo a 2 µg.mL-1 (grupo F, o en una perfusión de bupivacaína al 0,125% (grupo B. Se recogieron los siguientes parámetros: edad, nuliparidad, administración de analgesia epidural (sí/no, tipo de parto, duración de la dilatación, duración del expulsivo, causa de la cesárea, peso fetal, test de Apgar y pH arterial umbilical fetal. Resultados: Se recogieron datos de 576 mujeres. Se administró analgesia epidural en el 47,7% de las parturientas, de las cuales 29,4% recibieron fentanilo en la perfusión continua. La duración de los periodos de dilatación y expulsivo fue más larga en las mujeres con analgesia epidural (p = 0,01 y p = 0,03, respectivamente, con independencia de que recibieran o no opioides epidurales. La analgesia epidural con y sin opioides también se asoció a un mayor riesgo de parto instrumental (28%; p = 0,006, pero no a un incremento de la tasa de cesáreas. Las pacientes que recibieron opioides epidurales presentaron fiebre intraparto en el 12,8% de los casos, frente al 7,1% de las que sólo recibieron bupivacaína en la perfusión.

    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.

    To describe the MRI findings in ten patients of spinal epidural angiolipoma for differentiated diagnosis presurgery. Ten surgically proved cases of spinal epidural angiolipomas were retrospectively reviewed, and the lesion was classified according to the MR findings. Ten tumors were located in the superior (n = 4), middle (n = 2), or inferior (n = 4) thoracic level. The mass, with the spindle shape, was located in the posterior epidural space and extended parallel to the long axis of the spine. All lesions contained a fat and vascular element. The vascular content, correlating with the presence of hypointense regions on T1-weighted imaging (T1WI) and hyperintense signals on T2-weighted imaging, had marked enhancement. However, there were no flow void signs on MR images. All tumors were divided into two types based on the MR features. In type 1 (n = 3), the mass was predominantly composed of lipomatous tissue (> 50%) and contained only a few small angiomatous regions, which had a trabeculated or mottled appear. In type 2 (n = 7), the mass, however, was predominantly composed of vascular components (> 50%), which presented as large foci in the center of the mass. Most spinal epidural angiolipomas exhibit hyperintensity on T1WI while the hypointense region on the noncontrast T1WI indicates to be vascular, which manifests an obvious enhancement with gadolinium administration.

    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.

La etiología más frecuente es la disfunción del manguito de los rotadores, que supone más del 70% de los casos, incluyendo aquí la tendinitis, la bursitis y la rotura de éste o de alguno de sus componentes. Se han postulado diversos tratamientos para el hombro doloroso. El objetivo del estudio es exponer una nueva técnica para los pacientes que son resistentes a los tratamientos convencionales. Material y métodos: Se analizó la eficacia de la técnica mediante una escala analógica visual (EVA que se pasó a los pacientes en el momento basal y al mes posterior a su realización. En el mismo período se valoró el grado de satisfacción de los pacientes y el porcentaje de mejoría de éstos. Por último, se analizaron las complicaciones, si existieron, y se preguntó a los pacientes si repetirían la técnica o no. Resultados: La técnica se realizó en 12 pacientes. La EVA basal media fue de 8,5 ± 1 y descendió a 5,5 ± 3 tras el procedimiento. Cuando se analizan los pacientes en los que se obtuvo beneficio, el descenso de la EVA fue cercano a 5 puntos con respecto al basal. Cuando se analizan estos datos se podría decir que en patología artrósica el valor de la técnica es mayor que en los pacientes en los que predomina la patología de partes blandas. El porcentaje medio de mejoría en la muestra completa fue de 45,83 ± 42,05. Los pacientes en los que se realizó la técnica, ante la pregunta de si repetirían o no la técnica, 7 repetirían frente a 5 que no lo harían. No se recogió ninguna complicación derivada del procedimiento. Conclusiones: El bloqueo tricompartimental del hombro parece una técnica prometedora en el tratamiento del hombro doloroso, principalmente en los casos en los que la patología subyacente es de origen artrósico.Introduction: Painful

  10. Opiodes como coadyuvantes de la analgesia epidural en pediatría Opioids as adjuvants of epidural analgesia in the paediatric age

    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. However, its possible side effects, mainly respiratory depression, should be considered. Morphine is the mu agonist opioid most widely used for

  11. Recurrent acute low back pain secondary to lumbar epidural calcification

    International Nuclear Information System (INIS)

    Epidural calcification is a rare cause of back pain, and spontaneous epidural calcification has not been reported previously. We describe a patient with acute low back pain and signs of lumbar nerve root compression due to epidural calcification, as demonstrated by CT-scan and MRI. Radiological signs of spondylodiscitis led to a search for an infectious cause, which was negative, and her symptoms responded rapidly to NSAID treatment alone. Her symptoms recurred 18 months later, and further imaging studies again revealed epidural calcification, but with a changed distribution. Her symptoms were relieved once more by NSAID treatment alone. We propose that epidural calcification secondary to aseptic spondylodiscitis is the main cause of acute back pain in this patient. A possible mechanism may be the pro-inflammatory effects of calcium pyrophosphate or hydroxyapatite crystal deposition within the epidural space. (orig.)

  13. Langerhans' cell histiocytosis presenting with an intracranial epidural hematoma

    International Nuclear Information System (INIS)

    An 8-year-old boy developed vomiting and severe headache following minor head trauma. A CT scan of the head demonstrated a lytic lesion of the skull and adjacent epidural hematoma. Surgical evacuation and removal of the skull lesion and hematoma were carried out, and pathologic evaluation resulted in a diagnosis of Langerhans' cell histiocytosis (LCH). Epidural involvement of Langerhans' cell histiocytosis is very rare, and we report the first case of LCH presenting as an intracranial epidural hematoma. (orig.)

    This work relies on the development of a sensorized medical needle with an all-optical guidance (Lab in a Needle) system for epidural space identification. The device is based on the judicious integration of a Fiber Bragg grating sensor inside the lumen of an epidural needle to discriminate between different types of tissue and thus providing continuous and real time measurements of the pressure experienced by the needle tip during its advancement. Experiments carried out on an epidural training phantom demonstrate the validity of our approach for the correct and effective identification of the epidural space.

    Salmonella vertebral osteomyelitis is an uncommon complication of Salmonella infection. We report a case of a 57-year-old transgender male who presented with lower back pain for a period of one month following a fall. Physical examination only revealed tenderness over the lower back with no neurological deficits. MRI of the thoracic and lumbar spine revealed a spondylodiscitis at T10-T11 and T12-L1 and right posterior epidural collection at the T9-T10 level. He underwent decompression laminectomy with segmental instrumentation and fusion of T8 to L3 vertebrae. Intraoperatively, he was found to have acute-on-chronic osteomyelitis in T10 and T11, epidural abscess, and discitis in T12-L1. Tissue and wound culture grew Salmonella Typhi and with antibiotics susceptibility guidance he was treated with intravenous ceftriaxone for a period of six weeks. He recovered well with no neurological deficits. PMID:27034871

  19. 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 ABSTRACT BACKGROUND AND OBJECTIVES: Inadvertent venous catheterizations occur in approximately 9% of lumbar epidural anesthetic procedures with catheter placement and, if not promptly recognized, can result in fatal consequences. The objective of this report is to describe a case of accidental catheterization of epidural venous plexus and its recording by computed tomography with contrast injection through the catheter. CASE REPORT: A female patient in her sixties, physical status II (ASA, underwent conventional cholecystectomy under balanced general anesthesia and an epidural with catheter for postoperative analgesia. During surgery, there was clinical suspicion of accidental catheterization of epidural venous plexus because of blood backflow through the catheter, confirmed by the administration of a test dose through the catheter. After the surgery, a CT scan was obtained after contrast injection through the catheter. Contrast was observed all the way from the skin to the azygos vein, passing through anterior and posterior epidural venous plexuses and intervertebral vein. CONCLUSION: It is possible to identify the actual placement of the epidural catheter, as well as to register an accidental catheterization of the epidural venous plexus, using computed tomography with contrast injection through the epidural catheter.

CONCLUSIONES: La técnica combinada (raqui-peridural para analgesia de parto está próxima de lo ideal. Cuidados con la técnica de anti-sepsia son necesarios para realización de bloqueos espinales. La complicación presentada ocurrió sin la aparente falla en la realización de la técnica, siendo una cuestión que es inherente al riesgo - beneficio que la técnica proporciona.BACKGRAUND AND OBJECTIVES: Meningitis is a serious complication, although rare in regional anesthesia. This report aimed at presenting a case which evolved to meningitis after combined labor spinal-epidural analgesia. CASE REPORT: Laboring patient, 25 years old, second gestation and previous c-section. Combined labor spinal-epidural analgesia was induced with double-puncture. Twenty-four hours later she presented with headache at rest, fever and mild chills, which regressed with symptomatic medication. Headache worsened in the 5th day. There were vomiting and neck pain in the 10th day. Symptoms became more severe in the 13th day. Lumbar puncture was performed. Clinical history and CSF analysis were compatible with bacterial meningitis. CONCLUSIONS: Combined labor spinal-epidural analgesia is very close to being the ideal technique. Care must be taken with the sterile technique to induce spinal blockade. The reported complication has occurred without an apparent technique failure and is inherent to technique’s risk-benefit ratio.

    Spinal epidural lipomatosis is a rare condition which is described as the accumulation of fat in the extradural territory and often causes dural impingement. Spinal epidural lipomatosis has been implicated in causing a variety of neurologic impairments ranging from back pain, radiculopathy, claudication, myelopathy or even cauda equina syndrome. We report a 46-year-old female with obesity and a history of chronic back pain and radiculopathy who developed idiopathic Spinal epidural lipomatosis diagnosed by magnetic resonance imaging. The purpose of this report is to present a case of spinal epidural lipomatosis presenting with symptomatic cord compression and also remind this rare condition as a the differential diagnosis of epidural lesions in patients with risk factors.

    2012-01-01

    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.

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.

    Full Text Available Introduction. Thoracic epidural analgesia, combined with general anesthesia, is an established anesthetic choice for abdominal aortic surgery. However, there are controversies about the level of anesthesia as well as the dose and concentration of the local anesthetic used. The aim of the study was to compare the effects of two different concentrations of epidural bupivacaine on sevoflurane requirements and hemodynamic parameters during aortic surgery under combined epidural/general anesthesia. Methods and Material. Sixty patients scheduled for abdominal aortic surgery were randomly divided into two groups according to the concentration of local anesthetic used for epidural anesthesia: - Group 1- low concentration - where 0.125% bupivacaine was used, and - Group 2 - high concentration - where 0.5% bupivacaine was used at the beginning and then the concentration was reduced to 0.25%. Anesthesia was maintained with sevoflurane, the dose was adjusted to achieve the target entropy of 40-60. The measurements included the inspired sevoflurane concentrations, blood pressure, and heart rate at the beginning and every 5 min during the surgery. Results. Both groups had similar heart rate and blood pressure, but the inspired sevoflurane concentration was significantly higher and more variable in patients where bupivacaine 0.125% was used. Vasopressors were used more often and in higher doses in the 0.5% bupivacaine group, and in the same group the blood loss and fluid requirements were reduced. Conclusion. When 0.5% bupivacaine is used in combined thoracic epidural/ general anesthesia for aortic surgery, the sevoflurane concentrations are lower and less variable. In addition, the blood loss and fluid requirements are reduced.

Supuso un éxito editorial insólito hasta entonces porque reunía tres características novedosas: una actitud crítica ante la guerra de Marruecos, una integración de las novedades vanguardistas en la que su autor llamó literatura de avanzada y un posicionamiento del intelectual al lado de las reivindicaciones del pueblo. Sin embargo, aunque publicó otra novela un año después (La Venus mecánica, un libro teórico en el que definía la literatura que él propugnaba y practicaba (El nuevo romanticismo y algunas narraciones breves, Díaz Fernández se bloqueó y dejó la literatura narrativa que tan buenas expectativas levantó. Analizaremos las posibles causas de ese bloqueo.

  16. Caudal epidural anesthesia during intracavitary brachytherapy for cervical cancer

    International Nuclear Information System (INIS)

    It has been suggested that pain control during intracavitary brachytherapy for cervical cancer is insufficient in most hospitals in Japan. Our hospital began using caudal epidural anesthesia during high-dose-rate (HDR) intracavitary brachytherapy in 2011. The purpose of the present study was to retrospectively investigate the effects of caudal epidural anesthesia during HDR intracavitary brachytherapy for cervical cancer patients. Caudal epidural anesthesia for 34 cervical cancer patients was performed during HDR intracavitary brachytherapy between October 2011 and August 2013. We used the patients' self-reported Numeric Rating Scale (NRS) score at the first session of HDR intracavitary brachytherapy as a subjective evaluation of pain. We compared NRS scores of the patients with anesthesia with those of 30 patients who underwent HDR intracavitary brachytherapy without sacral epidural anesthesia at our hospital between May 2010 and August 2011. Caudal epidural anesthesia succeeded in 33 patients (97%), and the NRS score was recorded in 30 patients. The mean NRS score of the anesthesia group was 5.17 ± 2.97, significantly lower than that of the control group's 6.80 ± 2.59 (P = 0.035). The caudal epidural block resulted in no side-effects. Caudal epidural anesthesia is an effective and safe anesthesia option during HDR intracavitary brachytherapy for cervical cancer. (author)

    Thoracic epidural anaesthesia in anaesthetized children requires a meticulous technique and may have an increased success rate when the distance between skin and epidural space is known. The objective of this observational study was to measure the skin to epidural distance (SED) during thoracic epidural puncture in 61 children. The epidural puncture was performed using the loss of resistance technique with saline 0.9%. The distance from the needle tip to the point where the needle emerged from the skin was measured. The post-operative analgesia parameters were also measured. Skin to epidural distance correlated significantly with the age and weight of the children. The equation for the relation between SED (cm) and age was 2.15 + (0.01 x months) and for SED vs weight was 1.95 + (0.045 x kg). Despite considerable variability among individuals, the observed correlation of SED with both age and weight shows that this parameter may be helpful to guide thoracic epidural puncture in anaesthetized children.

El objetivo de este relato fue presentar un caso en que ocurrió bloqueo del nervio frénico, con comprometimiento ventilatorio en paciente con insuficiencia renal crónica, sometido a la instalación de fístula arterio-venosa extensa, bajo bloqueo del plexo braquial por la vía perivascular interescalénica. RELATO DEL CASO: Paciente del sexo masculino, 50 años, tabaquista, portador de insuficiencia renal crónica en régimen de hemodiálisis, hipertensión arterial, hepatitis C, diabetes melito, enfermedad pulmonar obstructiva crónica, sometido a la instalación de fístula arterio-venosa extensa en el miembro superior derecho bajo bloqueo de plexo braquial por la vía interescalénica. El plexo braquial fue localizado con la utilización del estimulador de nervio periférico. Se inyectaron 35 mL de una solución de anestésico local constituida de una mezcla de lidocaína a 2% con epinefrina a 1:200.000 y ropivacaína a 0,75% en partes iguales. Al final de la inyección el paciente estaba lúcido, pero sin embargo con disnea y predominio de incursión respiratoria intercostal ipsilateral al bloqueo. No había murmullo vesicular en la base del hemitórax derecho. La SpO2 se mantuvo en un 95%, con catéter nasal de oxígeno. No fue necesaria la instalación de métodos de auxilio ventilatorio invasivo. La radiografía del tórax reveló que el hemidiafragma derecho ocupaba el 5° espacio intercostal. El cuadro clínico se revirtió en tres horas. CONCLUSIONES: El caso mostró que hubo parálisis total del nervio frénico con síntomas respiratorios. A pesar de no haber sido necesaria la terapéutica invasiva para el tratamiento, queda el aviso aquí para la restricción de la indicación de la técnica en esos casos.BACKGROUND AND OBJECTIVES: Phrenic nerve block is a common adverse event of brachial plexus block.

    Full Text Available Spontaneous pneumomediastinum is a relatively rare benign condition. It may rarely be associated with one or combination of pneumothorax, epidural pneumatosis, pneumopericardium, or subcutaneous emphysema. We present a unique case with four of the radiological findings in a 9-year-old male child who presented to our emergency department with his parents with complaints of unproductive cough, dyspnea, and swelling on chest wall. Bilateral subcutaneous emphysema was palpated on anterior chest wall from sternum to midaxillary regions. His anteroposterior and lateral chest radiogram revealed subcutaneous emphysema and pneumomediastinum. His thorax computed tomography to rule out life-threatening conditions revealed bilateral subcutaneous, mediastinal, pericardial, and epidural emphysema without pneumothorax. He was transferred to pediatric intensive care unit for close monitorization and conservative treatment. He was followed-up by chest radiographs. He was relieved from symptoms and signs around the fifth day and he was discharged at the seventh day. Diagnosis of pneumomediastinum is often made based on physical findings and plain radiographs. It may not be as catastrophic as it is seen. Close cardiopulmonary monitorization is mandatory for complications and accompanying conditions. Most patients with uncomplicated spontaneous pneumomediastinum respond well to oxygen and conservative management without any specific treatment.

    This study was a retrospective analysis of 850 lumbar microdiscectomy (LMD) under epidural anesthesia (EA; n=573) or general anesthesia (GA; n=277) performed by the same surgeon and paid by invoice to the Social Security Institution of the Turkish Republic between April 2003 and May 2013. Although GA is the most frequently used method of anesthesia during LMD, the choice of regional anesthetia (epidural, spinal or a combination of these) differs between surgeons and anesthetists. Studies have reported that EA in surgery for lumbar disc herniation may be more reliable than GA, as it enables the surgeon to communicate with the patient during surgery, but few studies have compared the costs of these two anesthetic methods in LMD. We found that EA patient costs were significantly lower than GA patient costs (p0.05). The anesthetic method used during LMD affected the complication rate, cost and efficiency of operating room use. We suggest that EA is an anesthetic method that can contribute to health care cost savings and enable LMD to be completed with less nerve root manipulation and more comfort, efficacy, reliability and cost efficiency without affecting the success rate of the surgical procedure.

    Full Text Available Background. Thoracic epidural catheters provide the best quality postoperative pain relief for major abdominal and thoracic surgical procedures, but placement is one of the most challenging procedures in the repertoire of an anesthesiologist. Most patients presenting for a procedure that would benefit from a thoracic epidural catheter have already had high resolution imaging that may be useful to assist placement of a catheter. Methods. This retrospective study used data from 168 patients to examine the association and predictive power of epidural-skin distance (ESD on computed tomography (CT to determine loss of resistance depth acquired during epidural placement. Additionally, the ability of anesthesiologists to measure this distance was compared to a radiologist, who specializes in spine imaging. Results. There was a strong association between CT measurement and loss of resistance depth (P35 changed this relationship (P=0.007. The ability of anesthesiologists to make CT measurements was similar to a gold standard radiologist (all individual ICCs>0.9. Conclusions. Overall, this study supports the examination of a recent CT scan to aid in the placement of a thoracic epidural catheter. Making use of these scans may lead to faster epidural placements, fewer accidental dural punctures, and better epidural blockade.

    braquial es el territorio potencial para la absorción de anestésicos locales. Estudios de los estereoisómeros de la bupivacaína han venido demostrando un menor potencial de toxicidad de la fracción levógira (levobupivacaína, sobre el sistema cardiovascular. Sin embargo, se discute la eficacia anestésica (bloqueo sensitivo y motor, de la levobupivacaína en anestesia del neuro eje. Este estudio pretende demostrar la eficacia anestésica de la levobupivacaína, comparándola con la bupivacaína racémica en bloqueo de plexo braquial por la vía perivascular subclavia. MÉTODO: Cincuenta pacientes adultos de ambos sexos, ASA I y II, fueron sometidos a la anestesia de plexo braquial vía perivascular subclavia para procedimientos ortopédicos de miembros superiores con la ayuda de un neuroestimulador. Se dividieron de modo aleatorio, en dos grupos: G BUPI - bupivacaína racémica, G LEVO - levobupivacaína, en un volumen de 30 mL a 0,5%. El bloqueo sensitivo fue evaluado por el método de "picada de aguja" en los metámeros de C5 a C8; y el bloqueo motor, en los intervalos en minutos: 1, 2, 5, 10, 15, 20, 25, 30, o hasta la instalación del bloqueo en los movimientos de los dedos, la mano el antebrazo y el brazo. RESULTADOS: No hubo ninguna diferencia estadística entre los dos grupos en cuanto a la latencia, incidencia de fallas, grado del bloqueo motor e incidencia de fallas y grado del bloqueo motor e incidencia de fallas del bloqueo sensitivo, pero sí que se verificó la diferencia estadística de la latencia del bloqueo sensitivo en todos los metámeros analizados. No hubo efectos adversos inherentes a la aplicación del anestésico local. CONCLUSIONES: La levobupivacaína demostró una eficacia anestésica en el bloqueo de plexo braquial, igualable a la solución racémica usualmente utilizada.BACKGROUND AND OBJECTIVES: Brachial plexus block is used in surgical procedures of the upper limbs.

    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.Epidural

La hipótesis diagnóstica de anestesia subdural accidental, en estos casos, se limitó a los datos clínicos. Las complicaciones del bloqueo subdural pueden ser de las más variadas, más en su grande mayoría son de resolución fácil, desde que sean diagnosticadas y tratadas rápidamenteBACKGROUND AND OBJECTIVES: Epidural anesthesia is a widely used procedure nowadays. Accidental subdural anesthesia after epidural puncture is an uncommon complication. This report aimed at describing two cases of subdural injection which coincidentally have happened in consecutive anesthesias induced by the same anesthesiologist. CASE REPORTS: Case 1: Male patient, 41 years old, physical status ASA I, submitted to surgical ureteral calculi removal. Our choice was epidural anesthesia. Thirty minutes after beginning of induction, patient was communicative but sleepy with 100% SpO2, when he slowly began to show oxygen saturation decrease reaching 80% SpO2. Patient was unconscious with apnea and anisocoria. At this moment the diagnostic hypothesis was accidental subdural anesthesia. Patient was then intubated and maintained under mechanically controlled ventilation. After surgery, patient was referred to the recovery room and was discharged 6 hours after without any neurological complications. Case 2: Female patient, 82 years old, physical status ASA II, submitted to surgical proximal femur fracture fixation. Our choice in this case was continuous epidural anesthesia. Similar to the previous case, 30 minutes after she began to show SpO2 decrease, reaching 90%. Patient was uncons- cious with anisocoria, however without apnea. We decided to maintain the patient under constant surveillance and intubation was considered unnecessary. Our diagnostic hypothesis in this case was also accidental subdural

    BACKGROUND: The most common side effect of epidural or spinal anesthesia is hypotension with functional hypovolemia prompting fluid infusions or administration of vasopressors. Short-term studies (20 min) in patients undergoing lumbar epidural anesthesia suggest that plasma volume may increase when...... hypotension is present, which may have implications for the choice of treatment of hypotension. However, no long-term information or measurements of plasma volumes with or without hypotension after epidural anesthesia are available. METHODS: In 12 healthy volunteers, the authors assessed plasma (125I...... volunteers receiving hydroxyethyl starch. RESULTS: Plasma volume did not change per se after thoracic epidural anesthesia despite a decrease in blood pressure. Plasma volume increased with fluid administration but remained unchanged with vasopressors despite that both treatments had similar hemodynamic...

    An 8-year-old, male Boxer was examined for an acute onset of ambulatory paraparesis. Neurologic examination was consistent with a T3-L3 myelopathy. Myelography revealed an extradural spinal cord compression in the region of the T10-T13 vertebrae. On magnetic resonance (MR) imaging, a well-defined epidural mass lesion was detected. The mass was mildly hyperintense on T1-weighted, hyperintense on T2-weighted and STIR images compared to normal spinal cord and enhanced strongly and homogenously. Postmortem examination confirmed a primary epidural hemangiosarcoma. Findings indicated that the MRI characteristics of spinal epidural hemangiosarcoma may mimic other lesions including meningioma and epidural hemorrhages/hematomas of non-neoplastic etiology.

    LENUS (Irish Health Repository)

    2012-02-29

    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 Introduction:- Regional analgesia provides excellent pain relif in labour. This study was designed to compare combined spinal eqidural (CSE versus epidural block using a narcotic (sufentanil and local anaesthetic bupivacaine regarding their effects on progress of labour, method of delivery, pain relif, side effects and neonatal outcome. Patients and Methods :-Forty pregnant women ASA I and II were enrolled in this study. The women were randomly allocated to receive either CSE or epidural ( 20 patient of each . In CSE group analgesia was initiated with 10ug sufentanil with 2mg bupivacaine. In epidural group 10ml bupivacaine 0.125%.and 10ug sufentanil injected epidurally. In both groups the continuous infusion of 0.83% bupivacaine with 0.33ug/ml sufentanil at 10ml/hr adjusted as required. Maternal haemodynamics, analgesia characteristics VAPS, degree of motor block, were measured. Duration of labour, cervical dilation, maternal satisfaction and mode of delivery were assessed. Foetal outcome was assessed by 1 and 5 min. Apgar score and umbilical venous blood gases. Maternal and neonatal side effects were observed. The experimental study was done on 30 rats divided into 3 groups 10 rats of each. Control group (A injected intrathecally with saline, group (B injected intrathecally with 1.5ug/kg sufentanil (low dose, and group (C injected intrathecally with 7.5ug/kg sufentanil (high dose, the pervious doses were injected every 2hr. for 3 times then the spinal cord was obtained and stained for histological evaluation. Results:- The clinical study showed that no difference between the 2 groups for the degree of motor block or adequacy of analgesia, mode of delivery and Foetal outcome. The onset of analgesia was faster with CSE technique, more patient satisfaction and more pruritis. The histological results revealed that no detectable significant neurotoxic changes with the use of small dose of intrathecal sufentanil but mild changes occurred with high

    uso de bupivacaína racémica con levobupivacaína en anestesia peridural de pacientes sometidas a cesárea electiva. MÉTODO: Ensayo clínico eventual, doblemente encubierto, con gestantes estado físico ASA I y II. Las pacientes fueron distribuidas para recibir 20 mL de bupivacaína a 0,5% racémica ó 20 mL de levobupivacaína a 0,5%, ambas con 10 µg de sufentanil y vasoconstrictor. RESULTADOS: Participaron del estudio 47 pacientes, 24 en el grupo de la levobupivacaína y 23 en el grupo de la bupivacaína. Los grupos eran comparables entre sí en lo que se refiere a las características materno-fetales. Transcurridos 15 minutos después del término de la punción peridural, 62,5% de las pacientes del grupo de la levobupivacaína tenían Bromage 2 ó 3 contra 72,7% en el grupo de la bupivacaína (p = 0,83. Transcurridos veinte minutos, 66,7% de las pacientes del grupo de la levobupivacaína tenían Bromage 2 ó 3 contra 86,3% del grupo de la bupivacaína (p = 0,21. La complicación más frecuente fue la hipotensión arterial, encontrada en 16 (66,7% pacientes del grupo de la levobupivacaína y en 10 (43,5% pacientes del grupo de la bupivacaína (p = 0,11. CONCLUSIONES: La levobupivacaína y la bupivacaína fueron igualmente efectivas en el bloqueo peridural de pacientes sometidas a cesárea.BACKGROUND AND OBJECTIVES: Local anesthetic bupivacaine is found in two different enantiomers: levobupivacaine - S (- and dextrobupivacaine - R (+. Based on studies showing that S(- enantiomers are less cardiotoxic, their use has been increasing in clinical practice. This study aimed at comparing racemic bupivacaine and levobupivacaine in epidural anesthesia for elective cesarean section. METHODS: Randomized, double blind clinical trial enrolling physical status ASA I and II parturients. Patients were assigned to receive either 20 mL of 0.5% racemic bupivacaine or 20 mL of 0.5% levobupivacaine, both with 10 µg sufentanil and epinephrine 1:200,000. RESULTS: Participated in this

    The aim of our study was to determine if using the Epidrum to site epidurals improves success and reduces morbidity. Three hundred parturients requesting epidural analgesia for labour were enrolled. 150 subjects had their epidural sited using Epidrum and 150 using standard technique. We recorded subject demographics, operator experience, number of attempts, Accidental Dural Puncture rate, rate of failure to site epidural catheter, rate of failure of analgesia, Post Dural Puncture Headache and Epidural Blood Patch rates. Failure rate in Epidrum group was 9\\/150 (6%) vs 0 (0%) in the Control group (P = 0.003). There were four (2.66%) accidental dural punctures in the Epidrum group and none in the Control group (P = 0.060), and 2 epidurals out of 150 (1.33%) in Epidrum group were re-sited, versus 3\\/150 (2%) in the control group (P = 1.000). The results of our study do not suggest that using Epidrum improves success or reduces morbidity.

    Full Text Available Aims and Objectives: The risk assessment of epidural hematoma due to catheter placement in patients undergoing cardiac surgery is essential since its benefits have to be weighed against risks, such as the risk of paraplegia. We determined the risk of the catheter-related epidural hematoma in cardiac surgery based on the cases reported in the literature up to September 2012. Materials and Methods: We included all reported cases of epidural catheter placement for cardiac surgery in web and in literature from 1966 to September 2012. Risks of other medical and non-medical activities were retrieved from recent reviews or national statistical reports. Results: Based on our analysis the risk of catheter-related epidural hematoma is 1 in 5493 with a 95% confidence interval (CI of 1/970-1/31114. The risk of catheter-related epidural hematoma in cardiac surgery is similar to the risk in the general surgery population at 1 in 6,628 (95% CI 1/1,170-1/37,552. Conclusions: The present risk calculation does not justify not offering epidural analgesia as part of a multimodal analgesia protocol in cardiac surgery.

    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.

    A 70-year-old Greek lady presented with fever, arthralgias of knees, cervical and lumbar pain during the last month. On clinical examination the patient was found to have tenderness of the cervical and the lumbar spine with great motion restriction. The blood tests revealed high erythrocyte sedimentation rate and C-reactive protein, abnormal liver function tests and a positive rheumatoid factor. Serological test for Brucella was positive while cervical MRI revealed epidural abscess and spondylodiscitis. Conservative treatment with streptomycin (it was substituted by rifampicin after the third week) and doxycyclin for 4 months significantly improved her symptoms. The frequency as well as the diagnosis and management of this manifestation are discussed. PMID:23188848

    Background and Aims: Epidural morphine after caesarean section may cause moderate to severe pruritus in women. Epidural oxycodone has been shown in non-obstetric trials to reduce pruritus when compared to morphine. We hypothesised that epidural oxycodone may reduce pruritus after caesarean section. Methods: A randomised controlled trial was conducted in pregnant women at term who underwent caesarean section with combined spinal-epidural technique initiated with intrathecal fentanyl 15 μg. Women received either epidural morphine 3 mg or epidural oxycodone 3 mg via the epidural catheter after delivery. The primary outcome was the incidence of pruritus at 24 h after caesarean section. The secondary outcomes were the pruritus scores, treatment for post-operative nausea and vomiting (PONV), pain scores and maternal satisfaction. Results: One hundred women were randomised (group oxycodone O = 50, morphine M = 50). There was no difference between Group O and M in the incidence of pruritus (n [%] 28 [56%] vs. 31 [62%], P = 0.68) and the worst pruritus scores (mean [standard deviation] 2.6 (2.8) vs. 3.3 [3.1], P = 0.23), respectively. Both groups had similar pain scores at rest (2.7 [2.3] vs. 2.0 [2.7], P = 0.16) and sitting up (5.0 [2.3] vs. 4.6 [2.4], P = 0.38) at 24 h. Pruritus scores were lower at 4–8, 8–12 and 12–24 h with oxycodone, but pain scores were higher. Both groups had a similar need for treatment of PONV and maternal satisfaction with analgesia. Conclusion: There was no difference in the incidence of pruritus at 24 h between epidural oxycodone and morphine. However, pruritus scores were lower with oxycodone between 4 and 24 h after surgery with higher pain scores in the same period. PMID:27053782

    OBJECT The authors performed a pattern-of-failure analysis, with a focus on epidural disease progression, in patients treated with postoperative spine stereotactic body radiotherapy (SBRT). METHODS Of the 70 patients with 75 spinal metastases (cases) treated with postoperative spine SBRT, there were 26 cases of local disease recurrence and 25 cases with a component of epidural disease progression. Twenty-four of the 25 cases had preoperative epidural disease with subsequent epidural disease progression, and this cohort was the focus of this epidural-specific pattern-of-failure investigation. Preoperative, postoperative, and follow-up MRI scans were reviewed, and epidural disease was characterized based on location according to a system in which the vertebral anatomy is divided into 6 sectors, with the anterior compartment comprising Sectors 1, 2, and 6, and the posterior compartment comprising Sectors 3, 4, and 5. RESULTS Patterns of epidural progression are reported specifically for the 24 cases with preoperative epidural disease and subsequent epidural progression. Epidural disease progression within the posterior compartment was observed to be significantly lower in those with preoperative epidural disease confined to the anterior compartment than in those with preoperative epidural disease involving both anterior and posterior compartments (56% vs 93%, respectively; p = 0.047). In a high proportion of patients with epidural disease progression, treatment failure was found in the anterior compartment, including both those with preoperative epidural disease confined to the anterior compartment and those with preoperative epidural disease involving both anterior and posterior compartments (100% vs. 73%, respectively). When epidural disease was confined to the anterior compartment on the preoperative and postoperative MRIs, no epidural disease progression was observed in Sector 4, which is the most posterior sector.

    This a unique case of severe scapular pain following unintentional epidural space air injection during epidural steroid injection.A 70-year-old woman presented for a fluoroscopically guided C7-T1 interlaminar epidural steroid injection. Three injection attempts were made using the loss of resistance with air technique. On the first attempt the epidural space was entered, but contrast injection showed that the needle was intravenous. On the second attempt an equivocal loss of resistance with air was perceived and 5 mL of air was lost from the syringe. The needle was withdrawn and redirected, and upon the third needle passage the contrast injection showed appropriate epidural space filling up to the C4-5 level. Injection of betamethasone mixed in lidocaine was initially uneventful.However, 20 minutes post-injection the patient experienced sudden sharp and continuous pain along the medial edge of the scapula. After failing to respond to multiple intravascular analgesics, the patient was transferred to the emergency room. Her pain subsided completely following an intravenous diazepam injection. Cervical spine computerized tomography showed obvious air in the posterior epidural space from C4-5 to C6-7 as well as outside the spinal canal from (C4-T2). Having recovered fully, she was discharged the following morning. In reviewing the procedure, the equivocal loss of resistance on the second passage was actually a true loss of resistance to epidural space and air was unintentionally injected. Surprisingly, severe scapular pain resulted in a delayed manner after the steroid solution was injected. The authors theorize that unintentional prefilling of the epidural space with air prior to the injection of the subsequent steroid mixture added sufficient pressure to the epidural space to cause right-sided C4 nerve root stretching/entrapment and ensuing radicular pain to the right scapular border. The subsequent intravenous diazepam provided cervical muscle relaxation and

    Full Text Available JUSTIFICATIVA E OBJETIVOS: As técnicas de bloqueios nervosos guiados por ultra-som são baseadas na visualização direta das estruturas nervosas, da agulha de bloqueio e das estruturas anatômicas adjacentes. Desta maneira, é possível depositar a solução de anestésico local precisamente em torno dos nervos e acompanhar a sua dispersão em tempo real, obtendo-se, assim, um bloqueio mais eficaz, de menor latência, menor dependência de referências anatômicas, menor volume de solução anestésica e maior segurança. CONTEÚDO: O artigo revisa os aspectos relativos aos mecanismos físicos para formação de imagens, a anatomia ultra-sonográfica do neuroeixo e dos plexos braquial e lombossacral, os equipamentos e materiais empregados nos bloqueios, os ajustes do aparelho de ultra-som para melhorar as imagens, os planos de visualização das agulhas de bloqueio e as técnicas e o treinamento em bloqueios guiados por ultra-som. CONCLUSÕES: Os passos para se obter sucesso em anestesia regional incluem a identificação exata da posição dos nervos, a localização precisa da agulha, sem lesões nas estruturas adjacentes e, finalmente, a injeção cuidadosa de anestésico local junto aos nervos. Embora a neuroestimulação forneça grande auxílio na identificação dos nervos, esta não consegue, isoladamente, preencher todas essas exigências. Por isso, acredita-se que os bloqueios guiados por ultra-som serão a técnica de eleição para anestesia regional num futuro não muito distante.JUSTIFICATIVA Y OBJETIVOS: Las técnicas de bloqueos nerviosos guiados por ultrasonido se basan en la visualización directa de las estructuras nerviosas, de la aguja de bloqueo y de las estructuras anatómicas adyacentes.

    Full Text Available The aim of the investigation was to assess the efficacy of epidural anesthesia and analgesia during the integrated anesthetic management in spinal deformity surgery. Materials and Methods. The prospective randomized study involved 350 patients aged from 15 to 65 years, divided into two groups: group 1 (n=205 were given combined anesthesia — epidural and endotracheal anesthesia with sevoflurane and continuous epidural analgesia with ropivacaine, fentanyl and epinephrine after surgery; group 2 (n=145 had general anesthesia with sevoflurane and fentanyl, and systemic administration of opioids after surgery. We assessed systemic hemodynamics parameters (a non-invasive method, pain at rest and activities, parameters of hemostasis and fibrinolysis, plasma levels of stress hormones, cytokine levels at seven stages of the study (before, during and three days after surgery. Results. Patients in group 1 with epidural anesthesia had significantly less pain both at rest and motion. The most blood saving effect (up to 60% of blood loss was also found in group 1. Hemodynamic monitoring demonstrated epidural anesthesia not to lead to the life-threatening events of myocardial contractility, cardiac output, systemic vascular resistance and critical increasing of extravascular lung water. The impact of epidural anesthesia on hemostasis encompassed the activation of both coagulation and fibrinolysis. Furthermore, patients in group 1 compared to group 2 had significantly lower plasma levels of glucose, lactate, С-reactive protein, cortisol, and interleukins IL-1β, IL-6, IL-10. Conclusion. Comprehensive anesthetic protection in spinal deformity surgery based on epidural anesthesia provides adequate antinociceptive effects, inhibition of endocrine and metabolic stress response and correction of hemostasis problems.

    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

    2016-02-01

    Full Text Available BACKGROUND Lumbosacral radiculopathy is a common medical and socioeconomic problem with a lifetime prevalence estimated to be around 40%-60%. In 1930, Evans reported that sciatica could be treated by epidural injection. The use of epidural corticosteroid injection for the treatment of axial and radicular back pain was first reported in 1953. Lumbar Transforminal Epidural Steroid Injections (TFESIs are performed to provide symptomatic relief in patients with radicular pain. A transforaminal epidural steroid injection (TFESI using a small volume of local anaesthetic will anaesthetize the spinal nerve and also partially anaesthetize the dura, the posterior longitudinal ligament, the intervertebral disc and facet joint. For these reasons, fluoroscopy-guided TFESI has become the preferred approach to epidural space. AIMS AND OBJECTIVES To study the role of transforaminal epidural steroid injection in management of radiculopathy. SETTINGS AND DESIGN This prospective study was conducted in the Department of Orthopaedics, SKIMS Medical College and Hospital, Bemina, Srinagar, J and K, India, for a 2-year period from November 2012 to October 2014; 110 cases, both male and female in the age group of 20-60 years having back pain with radiculopathy of varied types and duration without neurodeficit were enrolled in the study. MATERIALS AND METHODS After selecting a patient for giving transforaminal block, we used a local anaesthetic (2% Xylocaine. Contrast media, e.g. Iohexol was used to demarcate the correct positioning of the needle. A spinal needle (20-25 gauge and 5mL syringe were used to deliver the drug. CONCLUSION Transforaminal epidural steroid injections with long acting anaesthetic is an excellent form of conservative treatment in management of low back ache with radicular pain. It is relatively safe, simple, economical and shortens the time of recovery from severe pain, avoids risks and complications of surgery and also avoids long periods of bed

    Full Text Available El síndrome de dolor regional complejo (SDRC se manifiestan con una clínica variada que se caracteriza por dolor, impotencia funcional, trastornos vaso-sudomotores y alteraciones tróficas. Está causado por una lesión primaria o una disfunción del Sistema Nervioso Periférico, estableciéndose dos grupos: SDRC-I que sustituye al término DSR y el SDRCII en lugar del término causalgia. Caso clínico: Varón de 37 años de edad, que tras ser sometido a una artroscopia de hombro comenzó a presentar dolor en el hombro y limitación funcional importante, así como ciertos cambios vasomotores de la misma extremidad, por lo que se diagnosticó de SDRC. El paciente siguió varias pautas de tratamiento analgésico por vía oral, fue sometido a numerosas infiltraciones intraarticulares, se realizaron bloqueos del ganglio estrellado e inició tratamiento rehabilitador. Durante estos meses la evolución clínica del paciente fue tórpida, reapareciendo el dolor en todas las ocasiones y sin presentar mejoría de la movilidad. Se decidió iniciar tratamiento con parches de lidocaína al 5%, con lo que se consiguió controlar el dolor del paciente y finalizó la rehabilitación con recuperación completa. El parche de lidocaína al 5% es un analgésico tópico desarrollado para el tratamiento del dolor neuropático de origen periférico. Está aprobado en EEUU para el tratamiento de la neuralgia postherpética. Sin embargo, se está probando su utilización en otras formas de dolor neuropático, como la neuropatía diabética, el dolor crónico de espalda y el dolor miofascial. El SDRC está asociado con una actividad anormal del sistema nervioso simpático, por lo que el bloqueo simpático mediante anestésicos locales es ampliamente utilizado. En el caso concreto de los parches de lidocaína al 5% se ha publicado un caso de tratamiento de forma efectiva. Este caso es similar al que nosotros describimos, que también fue refractario al tratamiento

    Full Text Available La historia de la anestesia intratecal y epidural ha discurrido en paralelo al desarrollo de la anestesia general. La primera reseña publicada sobre el uso de opioides para anestesia intradural la realizó un cirujano rumano, que presentó su experiencia en 1901 en París. Ha pasado casi un siglo hasta conseguir la utilización de opioides por vía epidural. En nuestros días, el uso de opioides intradurales y epidurales constituye una práctica clínica habitual para conseguir analgesia intra y postoperatoria. En los últimos 30 años, el uso de opioides epidurales se ha convertido en rutinario para el tratamiento del dolor del trabajo del parto y del manejo tanto del dolor agudo como crónico. Ha sido ampliamente asumido que cualquier opioide depositado en el espacio epidural o intratecal producirá una analgesia altamente selectiva medular y que esta será superior a la conseguida por otras técnicas analgésicas o vías de administración. Desafortunadamente esto simplemente no es verdad. De hecho, en multitud de ocasiones, los opioides son utilizados vía perimedular a pesar de que la evidencia clínica nos demuestra que no producen un efecto específico medular, o que la analgesia producida no es superior a la conseguida tras su administración intravenosa. Para realizar un uso apropiado de los opioides espinales, debemos comprender adecuadamente la fisiología y la farmacología clínica de estos fármacos y cuál produce analgesia selectiva medular y cuál no. Las diferencias son producto de la biodisponibilidad en los receptores específicos de su biofase medular en la sustancia gris. Esta es menor para los opioides lipofílicos, ya que son aclarados hacia el plasma con mayor rapidez que los hidrofílicos, y consecuentemente producen con mayor antelación efectos adversos supramedulares y su vida media es de menor duración. La morfina es probablemente el opioide con mayor acción selectiva medular tras su administración epidural o

    A few reports have demonstrated rare cases of Baastrup’s disease that involve epidural cysts that cause dural compression. However, there have been no reports of a midline epidural fibrotic mass being associated with Baastrup’s disease. A 60-year-old man presented with neurogenic claudication that had lasted for 5 years. Radiography showed anterolisthesis at the L4–L5 level, magnetic resonance imaging demonstrated severe stenosis due to a posterior noncystic mass, and the linear fluid signal tracked into the posterior epidural space at the L4–L5 level. A cleft in the ligamentum flavum was identified by probe at surgery, and this enabled the probe to be inserted into the epidural space without excising ligamentum flavum. Histological analysis showed that the fibrotic mass consisted of a collagen matrix that had a cystic component and exhibited a peripheral inflammatory reaction. This report shows that it is possible for an extended epidural cystic mass that occurs in Baastrup’s disease to change over time through peripheral inflammation into a cyst-containing fibrotic mass.

    Spinal epidural hematoma is a rare neurosurgical emergency in respect of motor and sensory loss. Identifiable reasons for spontaneous hemorrhage are vascular malformations and hemophilias. We presented a case of spontaneous epidural hematoma in an 18-year-old female patient who had motor and sensory deficits that had been present for 1 day. On MRI, there was spinal epidural hematoma posterior to the T2-T3 spinal cord. The hematoma was evacuated with T2 hemilaminectomy and T3 laminectomy. Patient recovered immediately after the surgery. Literature review depicted 112 pediatric cases (including the presented one) of spinal epidural hematoma. The female/male ratio is 1.1:2. Average age at presentation is 7.09 years. Clinical presentations include loss of strength, sensory disturbance, bowel and bladder disturbances, neck pain, back pain, leg pain, abdominal pain, meningismus, respiratory difficulty, irritability, gait instability, and torticollis. Most common spinal level was cervicothoracic spine. Time interval from symptom onset to clinical diagnosis varied from immediate to 18 months. Spinal epidural hematoma happened spontaneously in 71.8 % of the cases, and hemophilia was the leading disorder (58 %) in the cases with a definable disorder. Partial or complete recovery is possible after surgical interventions and factor supplementations. PMID:26033378

    Full Text Available Background: Laparoscopic cholecystectomy (LC is normally performed under general anesthesia. But of late this operation has been tried under regional anesthesia successfully without any added complications like epidural anesthesia. Aims: The aim of the study was to study the feasibility of performing LC under epidural anesthesia in normal patients so that the benefits could be extended to those high-risk patients having symptomatic gallstone disease and compromised cardio-pulmonary status where general anesthesia is contraindicated. Materials and Methods: In all, 20 patients with the American Society of Anesthesiologist′s class I or II were enrolled in the study. The level of epidural block and satisfaction score, both for the patient and the surgeon, were noted in the study. Results: The LC was performed successfully under epidural anesthesia in all but two patients who had severe shoulder pain in spite of giving adequate analgesia and were converted to general anesthesia. Conclusions: The LC can be performed safely under epidural anesthesia with understanding between patient and surgeon. However, careful assessment of complications in the patients should be done to make the procedure safer.

    Full Text Available Getu Ataro Department of Anesthesia, Jimma University, Jimma, EthiopiaI read the article by Phillips entitled, “Reducing gastrointestinal anastomotic leak rates: review of challenges and solutions”, published in the journal of Open Access Surgery with enthusiasm and found it crucial for perioperative management of patients with gastrointestinal (GI surgery, particularly anastomosis. I appreciate the author’s exhaustive search of literature and discussion with some limitation on review basics like methodology, which may affect the reliability of the review findings. The effects of risk factors for anastomosis leak, such as malnutrition, smoking, steroid use, bowel preparation, chemotherapy, duration of surgery, use of pressors, intravenous fluid administration, blood transfusion, and surgical anastomotic technique, were well discussed.1 However, from anesthesia perspective, there are some other well-studied risk factors that can affect healing of anastomosis wound and cause anastomosis leak. Among others, the effect of neostigmine and epidural block has been reported in many studies since half a century ago. View the original paper by Phillips

  20. Computational modeling of epidural cortical stimulation

    2008-12-01

    Epidural cortical stimulation (ECS) is a developing therapy to treat neurological disorders. However, it is not clear how the cortical anatomy or the polarity and position of the electrode affects current flow and neural activation in the cortex. We developed a 3D computational model simulating ECS over the precentral gyrus. With the electrode placed directly above the gyrus, about half of the stimulus current flowed through the crown of the gyrus while current density was low along the banks deep in the sulci. Beneath the electrode, neurons oriented perpendicular to the cortical surface were depolarized by anodic stimulation, and neurons oriented parallel to the boundary were depolarized by cathodic stimulation. Activation was localized to the crown of the gyrus, and neurons on the banks deep in the sulci were not polarized. During regulated voltage stimulation, the magnitude of the activating function was inversely proportional to the thickness of the CSF and dura. During regulated current stimulation, the activating function was not sensitive to the thickness of the dura but was slightly more sensitive than during regulated voltage stimulation to the thickness of the CSF. Varying the width of the gyrus and the position of the electrode altered the distribution of the activating function due to changes in the orientation of the neurons beneath the electrode. Bipolar stimulation, although often used in clinical practice, reduced spatial selectivity as well as selectivity for neuron orientation.

  1. Review of spinal epidural cavernous hemangioma

    International Nuclear Information System (INIS)

    The characteristics of spinal epidural cavernous hemangioma without primary origin in the vertebral bone were evaluated in 54 patients including our new case. The 36 male and 18 female patients were aged 5 to 78 years (mean 47 years). Most lesions were in the thoracic spine (80%) and on the dorsal side of the spinal cord (93%). The clinical course was mostly slowly progressive, with myelopathy in 33% at onset and 83% at admission. The lesion appeared isointense to the spinal cord on T1-weighted imaging, and isointense or slightly hypointense to the cerebrospinal fluid on T2-weighted imaging. Lesion without hemorrhage showed prominent homogeneous enhancement after administration of gadolinium-diethylenetriaminepenta-acetic acid because of the sinusoidal channel structure. Heterogeneous enhancement was caused by hematoma and/or post-hemorrhagic degeneration. The differential diagnosis of this disease includes metastatic tumor, Ewing's sarcoma, chordoma, eosinophilic granuloma, sarcoidosis, lipoma, hypertrophy of the posterior longitudinal ligament or the ligamentum flavum, meningioma, and neurinoma. The relationships between clinical course and surgery or outcome suggest that early diagnosis and total removal of the lesion before massive lesional bleeding occurs are necessary for a good outcome.

  4. MRI spectrum of findings in lumbosacral epidural lipomatosis

    International Nuclear Information System (INIS)

    Lumbosacral epidural lipomatosis (LEL) has been defined as a disease produced by excessive fat deposition within the spinal canal. In the pre MRI-era, this entity has been commonly overlooked. While a mild (or moderate) epidural fat hypertrophy is basically asymptomatic, severe LEL represents the symptomatic end-stage of this disease, conducing in many cases to surgical fat debulking. Since LEL may be concurrent with other substantial spinal abnormalities (e.g. disk herniation) MRI exams may increase our awareness of this condition to avoid its underestimation. MRI enables a reliable LEL characterization and may show its eventual reversibility in obese or corticosteroid receiving patients. This pictorial essay illustrates the usefulness of MRI to demonstrate the ongoing process of epidural fat accumulation in mild, moderate and severe LEL. The different morphologic patterns of the thecal sac produced by advanced LEL are analyzed. LEL and concurrent spinal disorders with superimposed neurological symptoms and signs are illustrated.

  5. Lumbar epidural varices: An unusual cause of lumbar claudication

    Directory of Open Access Journals (Sweden)

    Meenakshisundaram Subbiah

    2016-01-01

    Full Text Available Lumbar epidural varices can also present with radiculopathy similar to acute intervertebral disc prolapse (IVDP. However as the magnetic resonance imaging (MRI in these patients are usually normal without significant compressive lesions of the nerve roots, the diagnosis is commonly missed or delayed leading to persistent symptoms. We present a rare case of acute severe unilateral claudication with a normal MRI unresponsive to conservative management who was treated surgically. The nerve root on the symptomatic side was found to be compressed by large anterior epidural varices secondary to an abnormal cranial attachment of ligamentum flavum. Decompression of the root and coagulation of the varices resulted in complete pain relief. To conclude, lumbar epidural varices should be considered in the differential diagnosis of acute onset radiculopathy and claudication in the absence of significant MRI findings.

    2013-08-01

    Full Text Available Cauda equina syndrome is a neurological disorder defined by urinary and/or anal sphincter dysfunction, bilateral sciatica and bilateral motor and sensory deficits. Regarding the etiology, lumbar disc disease, spinal stenosis, tumors, haematomas, fractures, infectious diseases and ankylosing spondylitis are pathologies causing this syndrome. Spinal epidural haematomas are common amongst complications after spinal surgery. However the majority of these cases are asymptomatic, thus having little clinical importance. Symptomatic postoperative spinal epidural haematomas is a serious complication, and in order to prevent permanent neurologic deficit it requires urgent surgical intervention. This article aims to present the case of a patient with a spinal epidural haematoma after spinal stenosis surgery, causing cauda equina syndrome.

  7. Primary epidural lymphoma without vertebral involvement in a HIV-positive patient

    International Nuclear Information System (INIS)

    Epidural involvement is rarely associated with lymphoma, it being more typical of non-Hodgkin's lymphoma in advanced stages of the disease. The invasion of the epidural space is usually caused by the extension of a paravertebral mass or by the affected vertebrae. However, the epidural space alone can be involved. We present a case of epidural lymphoma in a patient who presented with clinical evidence of spinal cord compression. Magnetic resonance disclosed the existence of an epidural mass compressing and displacing the spinal cord without involving the adjacent vertebra or the associated paravertebral mass.

    Full Text Available Aim To determine the quality and duration of the analgesic and haemodynamic effects of clonidine when used as an additional analgesic for postoperative epidural analgesia in major vascularsurgery. Methods The prospective, single-blinded study involved 60 patients randomised into three groups (20 patients each: Group BM—bupivacaine 0.125% and morphine 0.1 mg/ml; Group BC—bupivacaine 0.125% and clonidine 5 μg/ml; Group MC—morphine 0.1 mg/ml and clonidine 5 μg/ml continuously infused at 5 ml/h. The quality and duration of the analgesia measured by the Visual Analogue Scale (VAS at rest and on movement, additional analgesia requirements, sedation scores, haemodynamic parameters and side effects(respiratory depression, motor block, toxic effects, nausea and pruritus were recorded. Results The average VAS scores at rest and on movement were significantly lower in Group MC at two, six and 24 hours following the start of epidural infusion (P<0.05. The duration of the analgesic effect after finishing the epidural infusion was significantly longer in Group MC (P<0.05. Patients from Group MC were intubated longer. Additional analgesia consumption, sedation scoresand haemodynamic profiles were similar in all three groups. Prurituswas more frequent in morphine groups (P<0.05, but other sideeffects were similar in all three groups.Conclusion Under study conditions, clonidine added to morphine,not 0.125% bupivacaine, provided significantly better pain scoresat two, six and 24 hours following the start of epidural infusionand the longest-lasting analgesia following the discontinuationof epidural infusion. However, patients from the Group MC weremechanically ventilated longer than patients from other two groups.Continuous monitoring of the patient is necessary after theadministration of clonidine for epidural analgesia.

    Background Cervicogenic headache (CEH) is caused by a structural abnormality in the cervical spine. Available treatments for CEH include medical therapy, local botulinum toxin injection, cervical epidural corticosteroid injection, and surgery. The objective of this study was to investigate the safety and efficacy of a continuous epidural block of the cervical vertebra.Methods Medical records were retrospectively analyzed for 37 patients diagnosed with CEH treated by a continuous epidural block of the cervical vertebra with lidocaine, dexamethasone, and saline (5 ml/min) for 3-4 weeks and triamcinolone acetonide 5 mg once weekly for 3-4 weeks. Pain was measured via the visual analogue scale (VAS) in combination with quality of life assessment. Outcome measures were patient-reported days with mild or moderate pain, occurrence of severe pain, and the daily oral dosages of non-steroidal anti-inflammatory drug use (NSAID).Results In the 3 months immediately preceding placement of the epidural catheter, the mean number of days with mild or moderate pain was 22.0±4.3. The mean occurrence of severe pain was (3.20±0.75) times and the mean oral dosage of NSAID was (1267±325) mg. During the first 6 months after epidural administration of lidocaine and corticosteroids, the mean number of days with mild or moderate pain, the mean occurrence of severe pain, and the mean daily oral dosages of NSAIDs were significantly decreased compared to 3-month period immediately preceding treatment (P <0.01). By 12 months post-treatment, no significant difference in these three outcome measures was noted.Conclusions Continuous epidural block of the cervical vertebra for patients with CEH is effective for at least six months. Further research is needed to elucidate mechanisms of action and to prolong this effect.

    Although bone infarction is a common feature in sickle cell disease, the involvement of the orbit is an unusual complication. Intracranial bleeding is another uncommon and serious complication. Few cases of orbital infarction alone have been reported. We report imaging findings (CT, bone scan, MRI) in a 16-year-old boy with sickle cell disease with orbital infarction and epidural hematoma. The precise cause of epidural hematoma is not well known, but it is probably related to vaso-occlusive episodes and the tearing of small vessels. (orig.)

    Full Text Available Anesthetic consideration of obstetric patients with pituitary disorders is an important topic to deal with. Few cases were reported with accidently discovered pituitary tumor complications especially in the postpartum period. A 26 years old primigravida lady with 39 weeks gestational period was reported to have severe headache and sudden loss of conscious after normal vaginal delivery with lumbar epidural anesthesia. Accidently discovered pituitary adenoma was proved after neurology, endocrine and ophthalmology consultations. Hence, undiagnosed pituitary adenomas should be taken in to consideration with unexplained postpartum generalized weakness and loss of conscious especially after exclusion of epidural anesthesia complications.

    Full Text Available This is a rare case of persistent Horner′s syndrome following epidural anesthesia and Caesarean section. A 33-year-old female presented with persistent ptosis and miosis following epidural anesthesia and Caesarian section several months prior. Magnetic resonance imaging (MRI/magnetic resonance angiography (MRA of head, neck, and chest were unremarkable. Medline search using terms Horner′s, epidural, spinal anesthesia, delivery, childbirth, Caesarian, and pregnancy identified 31 articles describing Horner′s syndrome in obstetric epidural anesthesia, of which 11 were following Caesarean section. The increased incidence of Horner′s syndrome in the setting of epidural anesthesia in pregnancy may be related to epidural venous engorgement and cephalic spread of the local anaesthetic, with disruption in the oculosympathetic pathway. It is important to include recent epidural anesthesia within the differential diagnosis of acute Horner′s syndrome in a postpartum female. Rarely, the ptosis may be permanent and require surgical intervention.

    ólogo. El objetivo de este relato fue presentar un caso de rotura de catéter epidural en analgesia de parto. RELATO DEL CASO: Paciente del sexo femenino, 33 años, GII, PI, entró en la maternidad en trabajo de parto. Después de dos horas de evolución, la paciente solicitó analgesia. Al realizársele el examen, se encontraba en fase activa del trabajo de parto, con dilatación cervical de 5 cm, dinámica uterina regular, bolsa rota, con dolor clasificado por la Escala Visual Analógica - VAS 10. Se inicia la analgesia de parto por la técnica combinada con doble punción. Durante la evolución se hizo una complementación analgésica por catéter. En la retirada hubo una pequeña dificultad y su consiguiente rotura. Se optó entonces por la realización de una tomografía axial computadorizada y una radiografía de la región lumbar que no mostró la presencia del fragmento del catéter. Visto que la paciente evolucionó asintomática y clínicamente, y sin señales de irritación radicular, dolor o infección, se procedió a las debidas orientaciones y a su alta. CONCLUSIONES: Los catéteres epidurales en la región lumbar son a veces raros, difíciles de retirar. Los factores que pueden aumentar las chances de formación de nudos y el riesgo de rotura del catéter se relacionaron. En ese caso, uno de los principales factores involucrados fue la introducción excesiva del catéter epidural lumbar. Por suerte, las complicaciones neurológicas son todavía más raras y secundando las directrices de una tracción lenta y suave en la falta de parestesias en la mayoría de los casos, el catéter se retira con éxito.BACKGROUND AND OBJECTIVES: Breakage of epidural catheters during their removal is rare, but it has been described. The anesthesiologist should be aware of the complications and proper handling of those catheters. The objective of this report was to present a case of breakage of an epidural catheter in labor analgesia. CASE REPORT: A 33-year old female, gravida

    abiertas con incisión subcostal, recibieron bloqueo intercostal (Grupo IC, n=30 o bloqueo interpleural (Grupo IP, n=30, ambos con 100 mg de bupivacaína 0,5% con adrenalina, para analgesia pós-operatoria. Fueron evaluados los tiempos de analgesia y las quejas relatadas por los pacientes. RESULTADOS: La calidad de la analgesia fue considerada buena para ambas técnicas. La duración media de analgesia fue de 505 minutos en el grupo IP y 620 minutos en el grupo IC, no habiendo diferencia estadística entre ellos. Náuseas, vómitos y dolor abdominal leve fueron las quejas pós-operatorias más frecuentes. No se constató cualquier complicación pós-operatoria asociada exclusivamente a los bloqueos, así como no fue evidenciado ningún caso de pneumotórax. CONCLUSIONES: Se concluye que las técnicas promovieron analgesia satisfactoria después de colecistectomia, siendo que el bloqueo interpleural presentó mayor facilidad de ejecución.BACKGROUND AND OBJECTIVES: Postoperative analgesia is a wish of all surgical patients and has been used by most anesthesiologists. In addition to opioids, local anesthetic agents have been employed for peripheral and central blocks. The purpose of this study was to evaluate and to compare intercostal and interpleural blocks for post-cholecystectomy analgesia. METHODS: Sixty patients undergoing open cholecystectomy with subcostal incision, received either intercostal block (Group IC, n = 30 or interpleural block (Group IP, n = 30, for postoperative analgesia, both with 0.5% bupivacaine (100 mg with epinephrine. 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

    To describe the MR imaging and clinical findings of spontaneous spinal epidural hematoma. The MR and clinical findings in six patients (M:F=3D4:2;adult:child=3D3:3) with spontaneous spinal epidural hematoma were reviewed. Five patients without any predisposing factor which might cause the condition and one with acute myelogenous leukemia were included. Emergency surgery was performed in two patients, and the other four were managed conservatively. The epidural lesion involved between three and seven vertebrae (mean:4.5), and relative to the spinal cord was located in the posterior-lateral (n=3D4), anterior (n=3D1), or right lateral (n=3D1) area. The hematoma was isointense (n=3D1) or hyperintense (n=3D5) with spinal cord on T1-weighted images, and hypointense (n=3D2) or hyperintense (n=3D4) on T2-weighted images. It was completely absorbed in four of five patients who underwent follow-up MR imaging, but not changed in one. The clinical outcome of these patients was complete recovery (n=3D4), spastic cerebral palsy (n=3D1), or unknown (n=3D1). Because of the lesion's characteristic signal intensity; MR imaging is very useful in the diagnosis and evaluation of spontaneous spinal epidural hematoma. (author)

    Background and Objective. Although minimally invasive surgical treatment of acute epidural hematoma attracts increasing attention, no generalized indications for the surgery have been adopted. This study aimed to evaluate the effects of minimally invasive surgery in acute epidural hematoma with various hematoma volumes. Methods. Minimally invasive puncture and aspiration surgery were performed in 59 cases of acute epidural hematoma with various hematoma volumes (13–145 mL); postoperative follow-up was 3 months. Clinical data, including surgical trauma, surgery time, complications, and outcome of hematoma drainage, recovery, and Barthel index scores, were assessed, as well as treatment outcome. Results. Surgical trauma was minimal and surgery time was short (10–20 minutes); no anesthesia accidents or surgical complications occurred. Two patients died. Drainage was completed within 7 days in the remaining 57 cases. Barthel index scores of ADL were ≤40 (n = 1), 41–60 (n = 1), and >60 (n = 55); scores of 100 were obtained in 48 cases, with no dysfunctions. Conclusion. Satisfactory results can be achieved with minimally invasive surgery in treating acute epidural hematoma with hematoma volumes ranging from 13 to 145 mL. For patients with hematoma volume >50 mL and even cerebral herniation, flexible application of minimally invasive surgery would help improve treatment efficacy. PMID:27144170

    Full Text Available Thoracic anesthesia offers particular challenge. Thoracic patients frequently have a painful wound after surgery. So analgesia after thoracic surgery is of particular significance. In the present study we assessed the efficacy of thoracic paravertebral and epidural blockade on post thoracotomy pain and pulmonary function. Thirty adult ASA I-III patients undergoing elective thoracic surgery were enrolled in this study. they were randomly divided into two groups : paravertebral and epidural group (15 patients each. Both percutaneous paravertebral and epidural catheters were placed preoperatively. Before chest closure each patient received a bolus dose of bupivacaine (0.25 % according to its height. This was followed by postoperative bupivacaine infusion (0.25 % 0.1 ml kg-1h ­1 in both groups. Also patients were encouraged to take supplementary doses of morphine from a patient controlled analgesia (PCA. Subjective pain relief was assessed on a linear visual analogue scale and pulmonary function was measured by spirometry. Stress responses to noxious stimuli was assessed by plasma levels of cortisol and glucose. Respiratory variables were recorded throughout the study period. Also sensory level of analgesia and performance status were assessed in the two groups. Although we found significantly lower visual analogue pain scores at rest and on maximal coughing in the paravertebral compared to the epidural group, no significant difference in patient controlled morphine requirements was noted between the two groups. Pulmonary function (FVC, FEV1 and PEFR was significantly better in the paravertebral group. Meanwhile no significant difference in respiratory variables was recorded between the two groups. Paravertebral block produced significantly diminished stress responses to noxious stimuli as manifested by less increase in plasma cortisol level than in epidural block. Sensory levels of analgesia and performance status was similar in both groups. Side

    utiliza a menudo para procedimientos estéticos de la mama y existen pocos relatos de su uso en mastectomías con exploración axilar. El presente estudio comparó la técnica con anestesia general en operaciones oncológicas de la mama. MÉTODO: Cuarenta pacientes que se dividieron en dos grupos. En el grupo epidural (n = 20 se hizo una epidural torácica con bupivacaína y fentanil asociados a la sedación con midazolam. El otro grupo (n = 20, recibió anestesia general convencional con propofol, atracurio y fentanil y mantenimiento con O2 e isoflurano. En el intraoperatorio y durante la operación, se verificó la necesidad de complementación de la anestesia o de la sedación y variables hemodinámicas. En el postoperatorio fue registrado el tiempo para el alta de la sala de recuperación postanestésica y hospitalaria, la intensidad del dolor y el consumo de analgésicos, efectos adversos y la satisfacción con la técnica anestésica. RESULTADOS: Los grupos fueron similares y no hubo diferencia en la duración de la operación. Se hizo necesario complementar la sedación en un 100% de las pacientes que recibieron anestesia epidural y en un 15% fue complementada la analgesia con infiltración de anestésico local en la axila. Hubo una mayor incidencia de hipertensión arterial en el grupo de la anestesia general y de hipotensión entre las que recibieron epidural. Ocurrió prurito en un 55% de las pacientes con anestesia epidural. Náusea (30% y vómito (45%, fueron más frecuentes entre las que recibieron anestesia general. La analgesia postoperatoria tuvo una mejor calidad y el consumo de analgésicos fue menor en el grupo de la anestesia epidural. El período de internación también fue menor. CONCLUSIONES: La técnica epidural tiene algunas ventajas con relación a la anestesia general y puede ser considerada una opción para la anestesia en mastectomías oncológicas con vaciado axilar.BACKGROUND AND OBJECTIVES: Thoracic epidural block is frequently used for

  9. MR epidurography: distribution of injectate at caudal epidural injection

    International Nuclear Information System (INIS)

    To (a) evaluate the feasibility of MR epidurography (MRE) and (b) assess the distribution of injectate using two different volumes at caudal epidural steroid injection. Twenty patients who were referred with symptomatic low back pain for caudal epidural steroid injection were assigned to have either 10 ml (9/20) or 20 ml (11/20) of injectate administered. Gadolinium was included in the injection. The patients proceeded to MRI where sagittal and coronal T1-weighted fat-saturated sequences were acquired and reviewed in the mid-sagittal and right and left parasagittal views at the level of the exit foramina. Gadolinium was observed at or above the L3/4 disc level in all 11 patients who received 20 ml (100 %), compared with only five of nine patients who received 10 ml (56 %). Injectate was seen to the L4 nerve root level in all 11 patients who received 20 ml (100 %) but only four out of nine patients who received 10 ml (44 %), not even reaching the L5 nerve root level in four further of these nine patients (44 %). Overall, there was a trend to visualize gadolinium at higher levels of the epidural space with higher volumes injected. Firstly, MR epidurography is a safe technique that allows excellent visualization of the distribution of gadolinium in the epidural space following injection via the caudal hiatus. Secondly, a volume of 10 ml is unlikely to treat L5/S1 disease in almost half of patients at caudal epidural steroid injection and at least 20 ml of injectate is likely required for any medication to reach the desired level.

  11. Ultrasound as a Screening Tool for Performing Caudal Epidural Injections

    International Nuclear Information System (INIS)

    The caudal approach to the epidural space has been used for decades to treat low back pain caused by lumbosacral root compression. The use of fluoroscopy during epidural steroid injection is the preferred method for placing the needle more accurately in the sacral hiatus, but it carries the risk of radiation hazard. The aim of the study was to assess the anatomical structure of the sacral hiatus and the feasibility of caudal epidural injections under ultrasound guidance. Two hundred and forty patients (male = 100, female = 140) with low back pain and sciatica who were candidates for caudal epidural injection were enrolled into this study. Ultrasound images of the sacral hiatus and bilateral cornua were obtained by a real-time linear array ultrasound transducer. The distance between bilateral cornua and the anterior and posterior wall of the sacrum were measured at the base (sacral hiatus). Under the guide of ultrasonography, we defined the injection successful if turbulence of medication fluid was observed in the sacral canal, but correct placement of the needle and injectant was confirmed on fluoroscopic view as the gold standard technique. The epidurogram showed that the injection was successful in 230 of the 240 patients (95.8%). In eight patients, the injection was not in the correct place in the sacral canal. The sacral hiatus could not be identified by ultrasound images in only two patients who had a closed sacral hiatus identified by fluoroscopy. The mean distance of the sacral hiatus was 4.7 ± 1.7 mm and the mean distance between bilateral cornua was 18.0 ± 2.8 mm. The mean duration of the procedure was 10.8 ± 6.8 minutes. No major complication was observed in the next month. In conclusion, ultrasound could be used as a safe, fast and reliable modality to observe the anatomic variation of the sacral hiatus and to perform caudal epidural injections

    Spontaneous spinal epidural hematoma is very uncommon cause of spinal cord compression. It is extremely rare in children and is mostly located in dorsal epidural space. Ventral spontaneous spinal epidural hematoma (SSEH) is even rarer, with only four previous reports in childrens. We are reporting fifth such case in a 14 year old male child. He presented with history of sudden onset weakness and sensory loss in both lower limbs with bladder bowel involvment since 15 days. There was no history...

  5. Histopathological Alterations after Single Epidural Injection of Ropivacaine, Methylprednizolone Acetate, or Contrast Material in Swine

    International Nuclear Information System (INIS)

    Purpose: The consequences from the injection of different types of drugs in the epidural space remains unknown. Increasing evidence suggests that localized inflammation, fibrosis, and arachnoiditis can complicate sequential epidural blockades, or even epidural contrast injection. We investigate the in vivo effect of epidural injections in the epidural space in an animal model. Materials and Methods: A group of ten male adult pigs, five punctures to each at distinct vertebral interspaces under general anesthesia, were examined, testing different drugs, used regularly in the epidural space (iopamidol, methylprednisolone acetate, ropivacaine). Each site was marked with a percutaneous hook wire marker. Histological analysis of the epidural space, the meninges, and the underlying spinal cord of the punctured sites along with staining for caspase-3 followed 20 days later. Results: The epidural space did not manifest adhesions or any other pathology, and the outer surface of the dura was not impaired in any specimen. The group that had the contrast media injection showed a higher inflammation response compared to the other groups (P = 0.001). Positive staining for caspase-3 was limited to <5% of neurons with all substances used. Conclusion: No proof of arachnoiditis and/or fibrosis was noted in the epidural space with the use of the above-described drugs. A higher inflammation rate was noted with the use of contrast media.

    mujeres obesas y con peso normal. MÉTODO: Evaluamos embarazadas con peso normal (IMC 30 kg.m-2, con feto único a término, sometidas a cesáreas de elección. Ese fue un estudio mono ciego y de ubicación secuencial, usando el método up-down (modificado por la regla de Narayana. Todas las pacientes recibieron bloqueo combinado raquiepidural con administración intratecal de dosis variables de bupivacaína hiperbárica a 0.75% más 10 µg de fentanil y 100 µg de morfina. La primera paciente recibió 9 mg de bupivacaína. La anestesia se suplementó cuando fue necesario, a través de un catéter epidural. El éxito de la anestesia, definido como bloqueo sensitivo hasta por lo menos T6, sin necesidad de anestesia suplementaria, fue el objetivo primario. La ED95 para un resultado satisfactorio fue determinada por un modelo logístico sin transformación logarítmica de las dosis. RESULTADOS: Veinte y cuarto embarazadas con peso normal y dieciséis embarazadas obesas participaron en este estudio. La ED95 estimada para todas las pacientes fue de 12,92 mg (IC 95%: 11,49 a 34,77. La ED95 estimada para las embarazadas con peso normal y las embarazadas obesas fue similar, 12,78 mg (IC 95%: 10,75 a + infinito y 11,86 mg (CI 95%: 11,31 a 15,61, respectivamente. CONCLUSIONES: Si la anestesia raquídea con inyección única es utilizada en cesáreas, las pacientes con peso normal y obesas deben recibir dosis parecidas de bupivacaína hiperbárica. A pesar de que no fuimos capaces de determinar con exactitud la ED95 en nuestro estudio, sí que podemos afirmar que es de por lo menos 11,49 mg.BACKGROUND AND OBJECTIVES: The effect of BMI on the spread of intrathecal bupivacaine is controversial.

    Spontaneous spinal epidural hematoma (SSEH) is a rare but real neurosurgical emergency. It is caused by atraumatic rupture of the vertebral epidural vein that results in nerve root or spinal cord compression. Most cases of SSEH have a multifactorial etiology, including congenital and acquired coagulopathies; platelet dysfunction; vascular malformation; tumors; uncontrolled hypertension; pregnancy; and, very rarely, activities requiring Valsalva. Herein we reported the case of a young pianist who was attacked by SSEH during piano practice. Playing the piano is a joyful, relaxing entertainment; however, this musical activity can be a highly demanding physical and mental exercise for pianists. Emotional and expressive performance, especially in professional performing, has been reported to result in significant increase of sympathetic and decrease of parasympathetic activities and thus influence the cardiorespiratory variables. The increased biomechanical stress from fluctuating hemodynamics was thought to trigger the rupture of her spinal arteriovenous malformation. PMID:24418452

    An 81-year-old man was treated with intravenous antibiotics for a soft tissue infection in a finger. Despite adequate antibiotic treatment, he developed signs of spinal cord injury caused by a cervical spinal epidural abscess. An emergency laminectomy was performed. The neurological impairment appeared to be irreversible, and the patient died. Spinal epidural abscess is a rare and serious complication ofa bacteraemia. It is often caused by an infection of the skin or soft tissue with Staphylococcus aureus. Given the risk of rapidly progressive and irreversible neurological damage, this complication must be treated as soon as possible. The treatment of choice is surgery. Conservative management with intravenous antibiotics is an option only under strict conditions. PMID:18624007

  9. Transient bladder and fecal incontinence following epidural blood patch

    2015-01-01

    Full Text Available Epidural blood patch (EBP is the currently accepted treatment of choice for postdural puncture headache because of its high initial success rates and infrequent complications. Many authors recommended a small volume (10-20 mL of blood to be delivered for an effective EBP. Here, we report an obstetric patient who developed a transient bladder and fecal incontinence after 19 mL of blood EBP at L 1 -L 2 level. Since the magnetic resonance image did not demonstrate any definitive spinal cord lesion, the exact mechanism remains unclear. We suggest that accumulation of blood performed at L 1 to L 2 level in a closed relationship with the sacral cord, may have trigger a significant pressure elevation of the epidural space at this level, resulting in a temporal spinal cord-related injury in the sacral cord.

    2008-01-01

    Full Text Available Spontaneous spinal epidural hematoma is a rare cause of acute spinal cord compression. A 25-year-old male presented with a history of sudden onset of complete quadriplegia with sensory loss below the neck along with loss of bowel and bladder control. He had no history of any constitutional symptoms. He reported 10 days later. He was managed conservatively and after two weeks of intensive rehabilitation he had complete neural recovery. The spontaneous recovery of neurological impairment is attributed to the spreading of the hematoma throughout the epidural space, thus decreasing the pressure with partial neural recovery. Conservative treatment is a fair option in young patients who present late and show neurological improvement. The neurological status on presentation will guide the further approach to management.

    A 39-year-old male with no previous medical history presented with abdominal and low back pain. Based on clinical and radiological findings he was diagnosed with L1/L2 osteomyelitis and epidural abscess. Further history taking revealed recent use of acupuncture for treatment of mechanical back pain. The patient was treated conservatively with an extended course of antibiotics, monitored with repeat MRI scans and had a full recovery with no neurological deficit. This is the first reported case of epidural abscess formation and osteomyelitis after acupuncture in the UK. As acupuncture becomes more commonly used in western countries, it is important to be aware of this rare but serious complication. PMID:26976275

    Spontaneous spinal epidural hematomas (SSEH) are heralded by spinal pain and progressive cord compression syndromes which may lead to permanent neurological disability or death if emergent neurosurgical intervention is delayed. It therefore must be considered early in the differential diagnosis of acute spinal cord compression syndrome. A case of spontaneous spinal epidural hematoma presenting as an acute myelopathy in a clarinet player who chronically used a nonsteroidal anti-inflammatory medication is presented. The case was remarkable for the rare complete spontaneous resolution of neurological function. Approximately 250 cases of SSEH have been reported in the medical literature, although only a handful of these patients have recovered spontaneously. This is the sixth report of such an event. The etiologies, contributing factors, disease progression, and treatment recommendations are discussed. PMID:8768163

    To bring attention to the MR imaging appearance of epidural hematoma (EDH) in the lumbar spine as a small mass often associated with disk herniation or an acute event. This paper will show our experience with this entity and describe criteria for its MR imaging appearance. Design and patients. Thirteen cases of prospectively diagnosed EDH of the lumbar spine were compared with 12 cases of prospectively diagnosed prominent epidural extrusion. Our criteria were retrospectively evaluated by the two authors for their presence or absence in each case. The chi-square test for nominal data was applied. MR imaging criteria utilized to distinguish EDH from disk herniation at our institution include: (1) signal different from disk, (2) high signal on T1-weighted images, either centrally or peripherally, (3) teardrop- or egg-shaped mass, in the sagittal plane, (4) size greater than half the vertebral body height in a craniocaudal dimension, (5) primarily retrosomatic epidural location, (6) plasticity - the mass is seen to conform closely to the contours of bone (e.g., in the lateral recess), (7) little or no disk space narrowing unless associated with disc herniation. Chi-square analysis demonstrated each criterion to significantly differentiate between EDH and extrusion. Only six of 13 EDH cases went to surgery in spite of their relatively large size. Two of six patients were diagnosed as having epidural clot consistent with hematoma at the time of surgery. The four patients who were not diagnosed at surgery revealed only small disk herniations or fragments of disk. The occurrence of EDH is more frequent than previously suspected. Spontaneous EDH is frequently associated with disk herniation and acute events such as sneezing or coughing. Most cases of spontaneous EDH will resolve prior to surgery with only the minority becoming chronic in order to be seen at surgery as an encapsulated mass. MR imaging can reliably identify EDH and distinguish between EDH and large disk

    Solitary, spinal epidural metastasis (SEM) that is not related to vertebral metastasis is very rare. And solitary SEM from prostatic cancer is rarely found in previously published reports. However, it is clinically significant due to the possibility of neurologic dysfunction, and it can be assessed by MRI. In this report, we show a case of solitary SEM arising from prostatic small cell carcinoma detected by MRI.

    Emine Rabia Koç

    2014-09-01

    Full Text Available Spontaneous spinal epidural hematoma is an uncommon cause of acute non-traumatic myelopathy and may present with various clinical phenotypes. Focal neurological symptoms can result in overlooking this differential diagnosis in patients presenting with neurological deficits and assuming the diagnosis of a stroke. Therefore, a thorough documentation of patient history is of great importance, since this can reveal symptoms suggestive of a different etiology. Here, we present a case of an 80-year-old female who was admitted with a hemiparesis without cortical or cranial neurological abnormalities. She mentioned of preceding shoulder and neck pain. Diagnosis of epidural hematoma was made by cervical magnetic resonance imaging. Symptoms resolved partially after surgical intervention. Our case illustrates the variation in the clinical presentation of spontaneous spinal epidural hematoma which can be misdiagnosed as stroke. Therefore, in patients with preceding neck, shoulder or interscapular pain and focal neurological deficits, this diagnosis should be included in the differential, particularly when cortical and cranial signs are lacking.

  6. Combined spinal epidural anesthesia in achondroplastic dwarf for femur surgery

    2011-11-01

    Full Text Available Achondroplasia is the commonest form of short-limbed dwarfism and occurs in 1:26,000- 40,000 live births. This is an autosomal dominant disorder with abnormal endochondral ossification whereas periosteal and intramembranous ossification are normal. The basic abnormality is a disturbance of cartilage formation mainly at the epiphyseal growth plates and at the base of the skull. The anesthetic management of achondroplastic dwarfs is a challenge to the anesthesiologist. Both regional as well as general anesthesia have their individual risks and consequences. We report a case of an achondroplastic dwarf in whom combined spinal epidural anesthesia was used for fixation of a fractured femur. The patient had undergone previous femur surgery under general anesthesia since he had been informed that spinal anesthesia could be very problematic. There was no technical difficulty encountered during the procedure and an adequate level was achieved with low-dose local anesthetics without any problem. Postoperative pain relief was offered for three consecutive postoperative days using epidural tramadol. We discuss the anesthetic issues and highlight the role of combined spinal epidural anesthesia with low-dose local anesthetics in this patient. This approach also helped in early ambulation and postoperative pain relief.

    cada vez más en una práctica frecuente. Con la menor probabilidad de promover lesiones vasculares, el ultrasonido se convierte en un instrumento interesante en la realización de bloqueos periféricos, especialmente en los pacientes que usan anticoagulantes o con disturbios de la coagulación. El objetivo de este estudio fue relatar dos casos en que se realizaron los bloqueos isquiático y femoral guiados por ultrasonido en pacientes anticoagulados. RELATO DE LOS CASOS: En el primer caso, la cirugía realizada consistió en la amputación del pie anterior izquierdo en función de una necrosis y de señales de infección. El segundo caso, fue una limpieza quirúrgica de la rodilla izquierda. Los pacientes presentaron disturbios de coagulación con una actividad de protrombina y tiempo de tromboplastina activado por encima de los valores normales. Los dos pacientes se sometieron al bloqueo femoral e isquiático guiado por ultrasonido, evolucionando sin alteración motora o sensitiva en los territorios de esos nervios y sin hematoma en la región local de la punción. CONCLUSIONES: La anticoagulación impone ciertas restricciones a la aplicación de las técnicas anestésicas regionales clásicas. Con el avance de los equipos y métodos de ultrasonido, hoy por hoy se puede identificar con alta precisión las estructuras vasculares y neurales. Eso posibilita que la punción guiada por ultrasonido sea más exacta, tanto para alcanzar el área de interés como para minimizar los riesgos de lesión vascular accidental. Hasta el presente momento, no se recomienda la realización de bloqueo periférico en pacientes anticoagulados o portadores de coagulopatías. Sin embargo, considerando que existen pocos relatos sobre bloqueos regionales con ultrasonido en situaciones de coagulopatías, la seguridad de tal técnica en esas condiciones todavía no se ha establecido.BACKGROUND AND OBJECTIVES: The use of the ultrasound to guide the puncture in peripheral nerve blocks has become

    SUMMARY Choosing the initial medications for intrathecal delivery is often confusing and not standardized. We describe a novel way for using a combined spinal-epidural technique to compare two first-line medications for intrathecal delivery; ziconotide and morphine (or hydromorphone). Five patients with intractable chronic or cancer pain were elected to have an intrathecal drug delivery system implanted for pain management. Each patient was given a 3-day inpatient trial with the combined spinal-epidural technique. The Visual Analog Scale, Numerical Rating Scale, short-term McGill questionnaire and opioid consumption were monitored daily. The results were used to develop a paradigm to describe how ziconotide can be used in practice. PMID:24645996

Todos los pacientes asociaron el hidromasaje en el hogar. Se administraron fármacos coadyuvantes para el control del dolor neuropático, paroxístico y persistente quemante. En los casos con trastornos de la consolidación ósea, se aplicó laserterapia local y TENS en los que presentaban mayor limitación funcional; así como técnicas de fisiatría. Se aplicó la escala análoga visual (EAV para evaluar la intensidad de la analgesia y se realizó examen físico para la valoración de los trastornos autonómicos. La función articular se consideró mediante la escala de Enneking y cols. para pacientes amputados, modificada por nosotros. Resultados: El dolor se controló en 33 pacientes y 28 descendieron su EAV a niveles álgicos tolerables, para un 89,70% de efectividad terapéutica. La función articular se recuperó en 30 pacientes y 20 quedaron con limitación leve, estos dos grupos con mejor respuesta correspondieron al 73,52% del total de los pacientes, 11 quedaron con limitación moderada y sólo 7, el 10,29% de ellos con limitación severa. Los trastornos vasomotores remitieron en la totalidad de los que presentaron respuesta favorable. Conclusiones: La intensidad de la 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 We report two cases of spontaneous spinal epidural hematoma with different clinical presentations without precipitating factors and a brief review of the literature. Our case first developed acute and had progressive cervical spinal cord signs that determined emergency decompressive laminectomy. On the other hand, the second patient, who was chronic, was operated almost five months after the initial symptoms and the radiological diagnosis was a large facet cyst. Early surgical intervention is the chosen treatment for spontaneous spinal epidural hematomas. Spinal surgeons should bear in mind that spontaneous spinal epidural hematomas may have different clinical presentations according to their location in order to perform a differential diagnosis.Fueron relatados dos casos de hematoma epidural espinal espontáneo con diferentes presentaciones clínicas sin factores precipitantes, y fue hecha una breve revisión de la literatura.

  1. Epidural analgesia practices for labour: results of a 2005 national survey in Ireland.

    LENUS (Irish Health Repository)

    Fanning, Rebecca A

    2012-02-01

    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.

  2. The knowledge and attitudes of nonanesthesia nurses regarding postoperative epidural analgesia.

    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.

    2006-09-01

    Full Text Available Abstract Background Epidural anaesthesia is used extensively for cardiothoracic and vascular surgery in some centres, but not in others, with argument over the safety of the technique in patients who are usually extensively anticoagulated before, during, and after surgery. The principle concern is bleeding in the epidural space, leading to transient or persistent neurological problems. Methods We performed an extensive systematic review to find published cohorts of use of epidural catheters during vascular, cardiac, and thoracic surgery, using electronic searching, hand searching, and reference lists of retrieved articles. Results Twelve studies included 14,105 patients, of whom 5,026 (36% had vascular surgery, 4,971 (35% cardiac surgery, and 4,108 (29% thoracic surgery. There were no cases of epidural haematoma, giving maximum risks following epidural anaesthesia in cardiac, thoracic, and vascular surgery of 1 in 1,700, 1 in 1,400 and 1 in 1,700 respectively. In all these surgery types combined the maximum expected rate would be 1 in 4,700. In all these patients combined there were eight cases of transient neurological injury, a rate of 1 in 1,700 (95% confidence interval 1 in 3,300 to 1 in 850. There were no cases of persistent neurological injury (maximum expected rate 1 in 4,600. Conclusion These estimates for cardiothoracic epidural anaesthesia should be the worst case. Limitations are inadequate denominators for different types of surgery in anticoagulated cardiothoracic or vascular patients more at risk of bleeding.

    Overgrowth of epidural fat, known as spinal epidural lipomatosis (SEL), can cause symptomatic compression of the spinal cord, conus medullaris, or cauda equina. Suggested predisposing factors such as obesity, steroid use, and diabetes mellitus have been based on a few reported cases, many of which were not surgically confirmed. There is a paucity of epidemiological data in surgically confirmed cases for this disorder. The purpose of this independently reviewed, retrospective, matched cohort analysis was to compare the demographics and incidence of comorbidities of patients who underwent lumbar decompression for SEL vs degenerative stenosis without SEL. Two surgeons' databases were reviewed to identify patients older than 18 years who underwent decompression surgery for magnetic resonance imaging-verified, symptomatic lumbar SEL. A matched control group comprised an equal number of patients with degenerative stenosis (n=14). Demographic data, body mass index, symptom type/duration, comorbidities, complications, treatment history, and associated pathology were collected from medical records. Previously suggested risk factors, such as obesity, endocrinopathy, and epidural steroid injections, were not significantly different between the SEL and control groups. Furthermore, there were no differences in operative times, complications, or blood loss. The only noted difference between the 2 groups was the preoperative duration of symptoms, on average double in patients with SEL. This series represents the largest of its kind reported to date. Because symptom duration was the only difference noted, it is postulated to be the result of lack of awareness of SEL. Future prospective study in a larger group of patients is warranted.

    Full Text Available Aim: Epidural blood patch has been used to treat spinal headache with varying success. An experimental model was designed to ascertain whether an epidural blood patch can be used to seal the needle puncture sites in dural repair. Materials and Methods: Bovine dura was secured to the lower end of an open-ended calibrated plastic cylinder. Multiple interrupted stitches were applied over a 02 cm length of the dura without any incision. The cylinder was filled with colored saline gradually with the dura placed in a dependent position. Height of the water column at which sutured dura leaked was recorded. A layer of fresh blood was laid over the dura and allowed to clot. The test was repeated and the hydrostatic pressure at which leak took place was noted again. The test was repeated three times. Similar studies were done with two specimens with 02-cm dural incisions repaired with interrupted stitches of 4-0 silk in one specimen and 4-0 prolene in another, and three specimens with 3-mm unsutured dural rent in one and dural punctures made with 23-G and 26-G spinal needles in the other two. Results: All the dural preparations leaked, at a very low hydrostatic pressure (<30 mm of H 2 O. By covering the needle puncture sites with clotted blood, a watertight closure could be achieved, that can withstand a much higher hydrostatic pressure (mean of 180 mm of H 2 O. Conclusion : The experimental findings indicate that an epidural blood patch does enhance the ability of a dural closure to prevent a leak; however, its utility in clinical setting is questionable.

  8. Epidural anesthesia as a cause of acquired spinal subarachnoid cysts

    International Nuclear Information System (INIS)

    Six patients with acquired spinal subarachnoid cysts secondary to epidural anesthesia were evaluated with MR imaging (seven patients) and intraoperative US (three patients). The cysts were located in the lower cervical and thoracic spine. Adhesions and irregularity of the cord surface were frequently noted. Associated intramedullary lesions, including intramedullary cysts and myelomalacia, were seen in two of the patients. Arachnoiditis was unsuspected clinically in three patients, and MR imaging proved to be the diagnostic examination that first suggested the cause of the patients symptoms. The underlying mechanism for the formation of these cysts is a chemically induced arachnoiditis

    Intrapartum fever is associated with excessive maternal interventions as well as higher neonatal morbidity. Epidural-related maternal fever (ERMF) contributes to the development of intrapartum fever. The mechanism(s) for ERMF has remained elusive. Here, we consider how inflammatory mechanisms may be modulated by local anesthetic agents and their relevance to ERMF. We also critically reappraise the clinical data with regard to emerging concepts that explain how anesthetic drug-induced metabolic dysfunction, with or without activation of the inflammasome, might trigger the release of nonpathogenic, inflammatory molecules (danger-associated molecular patterns) likely to underlie ERMF.

    Full Text Available BACKGROUND AND OBJECTIVES: In this study, we aimed to clarify the importance of residency grade and other factors which influence the success of thoracic epidural catheterization in thoracotomy patients. METHODS: After the ethical committee approval, data were recorded retrospectively from the charts of 415 patients. All patients had given written informed consent. The thoracic epidural catheterization attempts were divided into two groups as second-third year (Group I and fourth year (Group II according to residency grade. We retrospectively collected demographic data, characteristics of thoracic epidural catheterization attempts, and all difficulties and complications during thoracic epidural catheterization. RESULTS: Overall success rate of thoracic epidural catheterization was similar between the groups. Levels of catheter placement, number and duration of thoracic epidural catheterization attempts were not different between the groups (p > 0.05. Change of needle insertion level was statistically higher in Group II (p = 0.008, whereas paresthesia was significantly higher in Group I (p = 0.007. Dural puncture and postdural puncture headache rates were higher in Group I. Higher body mass index and level of the insertion site were significant factors for thoracic epidural catheterization failure and postoperative complication rate and those were independence from residents' experience (p < 0.001, 0.005. CONCLUSION: Body mass index and level of insertion site were significant on thoracic epidural catheterization failure and postoperative complication rate. We think that residents' grade is not a significant factor in terms overall success rate of thoracic epidural catheterization, but it is important for outcome of these procedures.

    Epidural electrostimulation has shown promise for spinal cord injury therapy. However, finding effective stimuli on the multi-electrode stimulating arrays employed requires a laborious manual search of a vast space for each patient. Widespread clinical application of these techniques would be greatly facilitated by an autonomous, algorithmic system which choses stimuli to simultaneously deliver effective therapy and explore this space. We propose a method based on GP-BUCB, a Gaussian process bandit algorithm. In n = 4 spinally transected rats, we implant epidural electrode arrays and examine the algorithm's performance in selecting bipolar stimuli to elicit specified muscle responses. These responses are compared with temporally interleaved intra-animal stimulus selections by a human expert. GP-BUCB successfully controlled the spinal electrostimulation preparation in 37 testing sessions, selecting 670 stimuli. These sessions included sustained autonomous operations (ten-session duration). Delivered performance with respect to the specified metric was as good as or better than that of the human expert. Despite receiving no information as to anatomically likely locations of effective stimuli, GP-BUCB also consistently discovered such a pattern. Further, GP-BUCB was able to extrapolate from previous sessions' results to make predictions about performance in new testing sessions, while remaining sufficiently flexible to capture temporal variability. These results provide validation for applying automated stimulus selection methods to the problem of spinal cord injury therapy. PMID:25974925

    Full Text Available The authors present two cases of intraventricular hemorrhage (IVH believed to be a result of epidural blood patching. The first was a 71-year-old woman who had new onset of nontraumatic IVH on computed tomography (CT scan after undergoing an epidural blood patch (EBP. This amount of intraventricular blood was deemed an incidental finding since it was of very small volume to account for her overall symptoms. The second patient, a 29-year-old woman, was found to have nontraumatic IVH three days after undergoing an EBP. This was seen on CT scan of the head for workup of pressure-like headaches, nausea, vomiting, and absence seizures. Conservative management was followed in both instances. Serial CT scan of the head in our first patient displayed complete resolution of her IVH. The second patient did not have follow-up CT scans because her overall clinical picture had improved significantly. This highlights a potential sequel of EBP that may be observed on CT scan of the head. In the event that IVH is detected, signs and symptoms of hydrocephalus should be closely monitored with the consideration for a future workup if warranted by the clinical picture.

    Aortic coarctation complicated with spinal artery aneurysm rupture is exceptionally rare and can be source of intraspinal hemorrhage with markedly poor prognosis. A 21-year-old man visited the emergency department because of chest and back pain along with immobility of bilateral lower limbs immediately after he woke up in the morning. Complete flaccid paraplegia and hypoesthesia in dermatome below bilateral T3 level and pain over axial region from neck to lumbar region were noted. A computed tomography excluded aortic dissection. Magnetic resonance imaging revealed a fusiform lesion involving the anterior epidural space from C7 to T2 level suspected of epidural hemorrhage, causing compression of spinal cord. He started intravenous corticosteroid but refused operation concerning the surgical benefits. Severe chest pain occurred with newly onset right bundle branch block that developed the other day. Coronary artery angiography revealed myocardial bridge of left anterior descending coronary artery at middle third and coarctation of aorta. He underwent thoracic endovascular aortic repair uneventfully. The patient was hemodynamically stable but with slow improvement in neurologic recovery of lower limbs. Aortic coarcation can cause paralysis by ruptured vascular aneurysms with spinal hemorrhage and chest pain that mimics acute aortic dissection. A history of hypertension at young age and aortic regurgitated murmurs may serve as clues for further diagnostic studies. Cautious and prudent evaluation and cross disciplines cares are essential for diagnosis and successful management of the disease. PMID:26275629

    The relationship between tachyphylaxis (measured as a decrease in the rate of regression of sensory levels of analgesia) during repeated epidural injections of lidocaine and both the distribution of lidocaine within the epidural space (as measured by spread of simultaneous injection of the tracer technetium-99m diethylenetriaminepentaacetate (99mTc-DTPA)) and elimination of lidocaine from the epidural space (as measured by serum concentrations of lidocaine) was investigated in 18 patients undergoing minor surgery during lumbar epidural analgesia. Twelve patients received four injections of 20 mL of 2% lidocaine at 2-hr intervals. Epidural distribution was assessed by injection of 99mTc-DTPA diluted in saline on the preoperative day and diluted in an equal volume of 2% lidocaine on the morning before surgery and again after the fourth injection of lidocaine 6 hr later. The distribution of 99mTc-DTPA in the epidural space was unchanged during the three measurements despite significant tachyphylaxis in both sensory analgesia and motor blockade (11 of 12 patients had sensory analgesia 2 hr after the first injection in contrast to only 3 of 12 patients during the third injection). In another six patients 20 mL of 2% lidocaine were injected three times at 2-hr intervals before surgery, with measurements of serum concentrations of lidocaine after the first and last injections. Despite tachyphylaxis (no patient had sensory analgesia 2 hr after the third injection), there was no difference in the rate of disappearance of lidocaine from the epidural space as assessed by plasma lidocaine concentration curves during the first and third injection (0.5 +/- 0.1 and 0.3 +/- 0.04 microgram.mL-1.min-1, respectively).

    Anaphylaxis during image-guided interventional procedures is a rare but potentially fatal event. Anaphylaxis to iodinated contrast is an established and well-recognized adverse effect. However, anaphylaxis to some of the other frequently administered medications given during interventional procedures, such as corticosteroids, is not common knowledge. During caudal epidural injection, iodinated contrast is used to confirm needle placement in the epidural space at the level of the sacral hiatus. A combination of corticosteroid, local anesthetic, and saline is subsequently injected. We describe a very rare case of anaphylaxis to a component of the steroid medication instilled in the caudal epidural space.

    An 8-year-old boy developed vomiting and severe headache following minor head trauma. A CT scan of the head demonstrated a lytic lesion of the skull and adjacent epidural hematoma. Surgical evacuation and removal of the skull lesion and hematoma were carried out, and pathologic evaluation resulted in a diagnosis of Langerhans' cell histiocytosis (LCH). Epidural involvement of Langerhans' cell histiocytosis is very rare, and we report the first case of LCH presenting as an intracranial epidural hematoma. (orig.)

    International Nuclear Information System (INIS)

    We present the case of an 86-year-old female with spontaneous spinal epidural hematoma. Although T1- and T2-weighted images showed the dilated posterior epidural space at the cervical spine, this finding was non-specific on conventional magnetic resonance imaging obtained 15 h after the onset of symptoms. Diffusion-weighted imaging with the use of periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER), which clearly revealed the high intensity hematoma, was useful for detection and diagnosis of acute spinal epidural hematoma

    Full Text Available BACKGROUND: Epidural anaesthesia is used extensively for both intra-operative and post-operative analgesia. This prospective randomized study was conducted using opioids epidurally for post-operative analgesia. Fentanyl is a pure opioid agonist. Butorphanol tartarate which is an agonist antagonist opioid is considered safer than pure opioid agonist. Hence, we compared epidural 4mg butorphanol and epidural 100 µg fentanyl for the relief of post-operative pain. AIMS AND OBJECTIVES: To compare the onset, duration, quality of analgesia, hemodynamic effects and side effects between the 2 study drugs. MATERIALS AND METHODS: 60 patients of either sex posted for elective lower abdominal and lower limb surgeries were randomly divided into 2 groups of 30 each. Group A received butorphanol 4mg epidurally. Group B received fentanyl 100 µg epidurally. All surgeries were done under lumbar epidural anaesthesia with catheter in situ. Post-operatively when patients complained of pain, intensity of pain was assessed using visual analogue scale [VAS]. When the VAS score was > 5, Group A received butorphanol 4mg diluted to 10 ml with NS or Group B received 100 µg fentanyl epidurally diluted to 10 ml with NS. Onset, duration, quality of analgesia, hemodynamic effects and incidence of side effects were compared between the two groups and treated accordingly. RESULTS: Demographic profile was comparable in both groups. Mean time of onset of analgesia was rapid (3.22 ±0.9 (S.D min in group B compared to group A (6.38± 1.26 (S.D min. Duration of analgesia was longer in group A (344.00 ±63.39 min compared to group B (227±38.12 min. Quality of analgesia was better with group A compared to group B. There was no significant difference in hemodynamic parameters in both groups. Sedation was the main side effect in group A. Incidence of pruritis, vomiting, hypotension and respiratory depression was more in group B. CONCLUSION: Epidural Butorphanol though has a delayed

    fue determinar cuál volumen de anestésico local en el bloqueo de plexo braquial por la vía posterior propicia analgesia postoperatoria para esas operaciones de manera más eficiente. MÉTODO: Noventa pacientes sometidos al bloqueo del plexo braquial por vía posterior fueron divididos aleatoriamente en tres grupos de 30. Grupo 1 - volumen de 20 mL; Grupo 2 - volumen de 30 mL; Grupo 3 - volumen de 40 mL. En todos los grupos, el anestésico usado fue la ropivacaína a 0,375%. El bloqueo se evaluó a través de la investigación de sensibilidad térmica utilizando algodón con alcohol y el dolor postoperatorio se evaluó secundando una escala numérica verbal (ENV en las primeras 24 horas. RESULTADOS: En los tres grupos la analgesia postoperatoria fue similar según los parámetros evaluados; ENV de dolor promedio,tiempo hasta el primer quejido de dolor y consumo de opioides en el postoperatorio. En el grupo de 20 mL hubo un mayor consumo de analgésicos no opioides después de la 12ª hora de postoperatorio. En los grupos de 30 y 40 mL la extensión del bloqueo fue significativamente mayor. CONCLUSIONES: Este estudio mostró que el bloqueo del plexo braquial por la vía posterior es una técnica que promueve analgesia eficaz para intervenciones quirúrgicas en el hombro. Los tres diferentes volúmenes estudiados promovieron analgesia similar. La mayor extensión del bloqueo con volúmenes mayores no se tradujo en una mejor analgesia.BACKGROUND AND OBJECTIVES: Arthroscopic surgeries of the shoulder are accompanied by severe postoperative pain.

    Full Text Available Cauda equina syndrome (CES may be caused by herniated disc, tumor, trauma, and spinal infections. However, CES due to epidural high-grade non-Hodgkin lymphoma (NHL is very rare. Up to our knowledge, few cases have been reported in the literature. We report a case of epidural high-grade NHL presenting as CES. A 55-year-old man presented with CES caused by extradural compression by primary NHL. The patient underwent an L4-L5 laminectomy. The operative findings were suggestive of well-demarcated epidural tumor. The final histopathological diagnosis revealed epidural high-grade NHL. NHL causing CES is rare. This report highlights the importance of keeping afresh the various causes of CES for prompt diagnosis and management.

    Full Text Available The purpose of this study was to determine the analgesic efficacy and clinical effects of morphine, fentanyl, methadone, lidocaine, lidocaine with epinephrine and saline (control when injected epidurally into the caudal epidural space in cattle. Epidural analgesia was achieved in five cattle on five successive occasions at weekly intervals. Analgesia was defined as a lack of response to hemostat pressure and pinprick in the skin of the perineal area and ventral aspect of the tail. The results demonstrated that while epidural lidocaine and lidocaine with epinephrine decreased the response to hemostat and pinprick compared to control, there was no reduction in response after the administration of morphine, methadone or fentanyl. Heart rate, pulse and respiratory rates were not significantly altered by any of the drugs. Neither did the drugs produce any change in the electrocardiogram (ECG of the animals.

    Spontaneous spinal epidural hematoma is very uncommon cause of spinal cord compression. It is extremely rare in children and is mostly located in dorsal epidural space. Ventral spontaneous spinal epidural hematoma (SSEH) is even rarer, with only four previous reports in childrens. We are reporting fifth such case in a 14 year old male child. He presented with history of sudden onset weakness and sensory loss in both lower limbs with bladder bowel involvment since 15 days. There was no history of trauma or bleeding diasthesis. On clinical examination he had spastic paraplegia. Magnetic resonance imaging (MRI) of dorsal spine was suggestive of ventral spinal epidural hematoma extending from first to sixth dorsal vertebrae. Laminectomy of fourth and fifth dorsal vertebrae and complete evacuation of hematoma was done on the same day of admission. Postoperatively the neurological status was same. PMID:27114667

    We report a case of symptomatic epidural lipomatosis in an 8-year-old girl with Cushing's syndrome secondary to longstanding high-dose steroid therapy for Crohn's disease. MR imaging of the spine revealed massive diffuse epidural fat compressing the entire spinal cord with T2 prolongation in the central gray matter of the cord suggesting ischemic myelopathy. This finding has not been previously demonstrated on imaging. A proposed mechanism underlying these findings is discussed. (orig.)

    Full Text Available This study was designed to investigate the influence of saline injections as epidural top-up on the sensory block duration, quality and hemodynamic effects of unilateral spinal anesthesia. The cases from ASA I-Il containing of 18-65 age group were randomly separated into three groups. For the purpose of unilateral spinal anesthesia, 6 mg 0.5% ‘heavy’ bupivacaine and for the purpose of epidural top-up, 10 mL saline were applied to the each patients of the groups. The study protocol was designed as:Ist group: Coming after the epidural catheter installation, unilateral spinal anesthesia was applied (n=20.IInd group: At first, unilateral spinal anesthesia was applied and after one minute, epidural top-up was done via the pre-installed epidural catheter (n=20.IIIrd group: At first the epidural catheter was installed and epidural top-up was applied. After one minute, unilateral spinal anesthesia was fulfilled (n=2O. Starting from the pre-anesthesic period, the hemodynamic data and following the anesthesia, the sensorial and motor block levels were recorded and evaluated.As the outcome of the inter-groups comparison of heart rate and mean arterial pressure, a statistically note-worthy differance was not determined; statistically significant but clinically acceptable hemodynamic changes were observed in intra-group evaluations, when the data was compared with control levels. The sensorial block levels were significantly higher in group II and significantly lower in group III.The application of 10 mL saline via epidural catheter 1 minute after the unilateral spinal anesthesia and remaining the patient leaning on the side of the extremity to be operated for 15 minutes improves the sensory block level of unilateral spinal anesthesia. It is determined that, for the lower extremity surgical operations with 1-1.5 hour estimated period, this method alone can be a worthwhile alternative.

    We report a healthy patient with postpartum headache and neck stiffness which were diagnosed as symptoms of pseudoaneurysm of vertebral artery. She had received a Cesarean section under the spinal anesthesia, and complaint of headache and neck stiffness. Epidural blood patches were done twice, but symptoms persisted. Eight days later, she experienced sensory disturbance and emergent laminectomy was done. When persistent postpartum headache occurs after epidural blood patch, more precise differential diagnosis should be made and considering other possible pathologies. PMID:27066211

    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.

    Conclusions: Maternal outcome in labour analgesia is similar with 100 mg I/M tramadol and epidural ropivacaine. There is no significant difference between duration of labour, rate of LSCS, incidence of instrumental delivery and neonatal outcome in the two modes of analgesia. Analgesic efficacy with epidural ropivacaine seems to be better compared to intramuscular tramadol. [Int J Reprod Contracept Obstet Gynecol 2016; 5(6.000: 1722-1727

    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.

    Caring for obese pregnant women presents challenges for all medical professionals. Despite a lack of supporting evidence, expert opinion and international guidelines suggest early labour epidural insertion for obese women. Anecdotally this is not supported by all anaesthetists. This qualitative study explored the experiences of anaesthetists regarding early epidural analgesia in obese parturients, to answer the research question: Are anaesthetists consistent in how they apply early epidural analgesia in obese parturients? Personal in-depth interviews with 42 specialist anaesthetists working in south-east Queensland, Australia, were completed between February and April, 2015. Leximancer™ text analysis software applied a validated algorithm to the data to identify themes and concepts. The major themes were explored by the first author to answer the research question. Three major themes were identified: the demands associated with caring for obese women; concern regarding the anaesthetic technique used in obese women; and the importance of communication with obstetric staff. Disagreement regarding interpretation and application of early epidural analgesia was identified within this group of anaesthetists. These anaesthetists were inconsistent in how they interpreted and applied early epidural analgesia for obese parturients, with some questioning the validity of the practice. The combination of uncertainty, urgency and technical difficulty presented by obese parturients provoked anxiety in these clinicians, particularly the anticipation of unplanned general anaesthesia. Consistent anaesthetic practice could improve the implementation of early epidural analgesia in obese parturients. PMID:27608347

    In order to determine the analgesic and cardiovascular effects of the combination of epidural ketamine and lidocaine, 6 sedated cats were studied. Six healthy, young cats were used in a prospective randomised study. Each cat underwent 3 treatments, at least 1 week apart, via epidural injection: (1) ketamine (2.5 mg/kg), (2) lidocaine (4.0 mg/kg), and (3) ketamine (2.5 mg/kg) plus lidocaine (4.0 mg/kg). Epidural injections were administered through the lumbosacral space. Analgesia, motor block, sedation, heart rate, arterial blood pressure, respiratory rate and arterial oxygen saturation were measured. Rectal temperature was compared before and after sedation as well as after epidural administration of the drugs. Epidural administration of the ketamine/lidocaine combination induced prolonged analgesia extending from the coccygeal to the T13-L1 dermatomes, leading to severe ataxia. Cardiovascular effects were significant in all treatments: heart rate decreased, but there was a minimal reduction in arterial pressure. It was concluded that adding a dose of ketamine to epidural lidocaine in cats is feasible and effective. PMID:19831267

Recientes experimentaciones en animales sugerían que la modificación de la relación enantiomérica de la bupivacaína racémica podría contribuir para su eficacia terapéutica y diminución de su toxicidad potencial. El objetivo del presente estudio fue comparar la eficiencia de la mezcla enantiomerica de bupivacaína (S75-R25 con la levógira pura S(-100 en la anestesia peridural lumbar para cirugías de várices de los miembros inferiores. MÉTODO: El estudio envolvió 30 pacientes del sexo femenino con edades entre 15 y 65 años, estado físico ASA I ó II, programados para cirugía electiva de várices. En test aleatorio y duplamente encubierto, los pacientes fueron divididos en dos grupos de 15: Grupo S75-R25 - 20 ml (100 mg de mezcla enantiomerica de bupivacaína a 0,5% (S75-R25 - y Grupo Levógiro - 20 ml (100 mg de bupivacaína levógira S(-100% a 0,5% sin adyuvante. Fueron comparadas las características del bloqueo sensitivo y motor, bien como la incidencia de efectos colaterales. RESULTADOS: Fueron detectadas diferencias intergrupales relacionadas a las características demográficas y un mayor tiempo quirúrgico en el grupo S75-R25. La dispersión mas rápida y la menor potencia analgésica de la mistura isomérica exhibieron significancia estadística. No hubo diferencia significativa relacionada a la ocurrencia de efectos colaterales. El grupo levógiro presentó menor relajamiento muscular. CONCLUSIONES: La reducción de la incidencia de efectos colaterales, la receptividad del método por los pacientes, la ausencia de sintomatologia neurológica transitoria pós-operatoria apuntan para la aplicación segura de ambas las soluciones en anestesia peridural lumbar para cirugía de várices de los miembros

Avaliaram-se FC, f, PAS, PAM, PAD, T°C, tempo de bloqueio motor e analgesia pós-operatória por meio de escala analógica visual. Houve elevação da FC no CIV e diminuição desse parâmetro no CEP. As pressões arteriais mantiveram-se dentro dos valores fisiológicos e não foram observadas diferenças na f e T°C. O tempo de duração do bloqueio anestésico foi potencializado nos grupos que receberam cetamina epidural, diferindo significativamente em relação ao controle. O tempo para a analgesia resgate não diferiu entre os grupos. Conclui-se que a administração de cetamina pela via epidural, por infusão contínua intravenosa ou pela associação de ambas promoveu estabilidade cardiorrespiratória no período transcirúrgico, porém não foi capaz de prolongar a duração da analgesia pós-operatória em cães submetidos à osteossíntese de fêmur.Ketamine has demonstrated analgesic effects in subanesthetic doses, besides the maintenance of stability of physiological parameters.

Data were collected for three postoperative days (POD on: pain scores; supplemental opioids; medications for respiratory depression, nausea, and pruritus, and distance ambulated during physical therapy.Results: Pain scores were similar until subjects were transitioned to another analgesic approach on POD 2; after that time, pain scores increased in Group EPID, although they decreased in Group EREM. Supplemental opioids were used more on POD1 in Group EREM than in Group EPID, although time to first opioid and total daily morphine equivalents were similar. Naloxone and antiemetics, not antipruritics, were used more in Group EREM. Distance ambulated after THA was greater in Group EREM than in Group EPID.Conclusions: These results suggest that EREM is associated with better postoperative ambulation and analgesia during the transition to oral or intravenous analgesics, although a higher incidence of side-effects was evident.Keywords: continuous epidural morphine infusion, extended-release epidural morphine, lower extremity arthroplasty, ambulation, postoperative pain, side-effects

    Cervical interlaminar epidural steroid injections (ESIs) are commonly performed as one part of a multi-modal analgesic regimen in the management of upper extremity radicular pain. Spinal epidural hematoma (SEH) is a rare complication with a reported incidence ranging from 1.38 in 10,000 to 1 in 190,000 epidurals. Current American Society of Regional Anesthesia (ASRA), American Society of Interventional Pain Physicians (ASIPP), and the International Spine Intervention Society (ISIS) recommendations are that non-steroidal anti-inflammatory drugs (NSAIDs) do not need to be withheld prior to epidural anesthesia. We report a case wherein intramuscular ketorolac and oral fluoxetine contributed to a SEH and tetraplegia following a cervical interlaminar (ESI). A 66 year-old woman with chronic renal insufficiency and neck pain radiating into her right upper extremity presented for evaluation and was deemed an appropriate CESI candidate. Cervical magnetic resonance imaging (MRI) revealed multi-level neuroforaminal stenosis and degenerative intervertebral discs. Utilizing a loss of resistance to saline technique, an 18-gauge Tuohy-type needle entered the epidural space at C6-7. After negative aspiration, 4 mL of saline with 80 mg of methyl-prednisolone was injected. Immediately thereafter, the patient reported significant spasmodic-type localized neck pain with no neurologic status changes. A decision was made to administer 30 mg intramuscular ketorolac as treatment for the spasmodic-type pain. En route home, she developed a sudden onset of acute tetraplegia. She was brought to the emergency department for evaluation including platelet and coagulation studies which were normal. MRI demonstrated an epidural hematoma extending from C5 to T7. She underwent a bilateral C5-T6 laminectomy with epidural hematoma evacuation and was discharged to an acute inpatient rehabilitation hospital. Chronic renal insufficiency, spinal stenosis, female gender, and increasing age have been

    Full Text Available Abstract Background Lumbar spinal stenosis is one of the most common causes of low back pain among older adults and can cause significant disability. Despite its prevalence, treatment of spinal stenosis symptoms remains controversial. Epidural steroid injections are used with increasing frequency as a less invasive, potentially safer, and more cost-effective treatment than surgery. However, there is a lack of data to judge the effectiveness and safety of epidural steroid injections for spinal stenosis. We describe our prospective, double-blind, randomized controlled trial that tests the hypothesis that epidural injections with steroids plus local anesthetic are more effective than epidural injections of local anesthetic alone in improving pain and function among older adults with lumbar spinal stenosis. Methods We will recruit up to 400 patients with lumbar central canal spinal stenosis from at least 9 clinical sites over 2 years. Patients with spinal instability who require surgical fusion, a history of prior lumbar surgery, or prior epidural steroid injection within the past 6 months are excluded. Participants are randomly assigned to receive either ESI with local anesthetic or the control intervention (epidural injections with local anesthetic alone. Subjects receive up to 2 injections prior to the primary endpoint at 6 weeks, at which time they may choose to crossover to the other intervention. Participants complete validated, standardized measures of pain, functional disability, and health-related quality of life at baseline and at 3 weeks, 6 weeks, and 3, 6, and 12 months after randomization. The primary outcomes are Roland-Morris Disability Questionnaire and a numerical rating scale measure of pain intensity at 6 weeks. In order to better understand their safety, we also measure cortisol, HbA1c, fasting blood glucose, weight, and blood pressure at baseline, and at 3 and 6 weeks post-injection. We also obtain data on resource utilization

    Lower oesophageal peristalsis and lower oesophageal sphincter (LOS) pressure during thoracic epidural analgesia (TEA) were studied in 20 healthy volunteers. After oesophageal manometric baseline recordings, 10 volunteers received 4 mg epidural morphine. The other ten received 0.5% bupivacaine epidurally in sufficient amounts to block the sympathetic innervation of the oesophagus. Thereafter oesophageal manometry was repeated. During epidural morphine oesophageal peristalsis, resting LOS pressure and the contraction of LOS after swallowing did not change, but the relaxation of the LOS in response to swallowing decreased significantly (P less than 0.01). Following TEA with bupivacaine, neither distal oesophageal peristalsis nor LOS pressure changed. PMID:3414347

Iran J Child Neurol. 2013  Spring;7(2:47-50.Abstract Spontaneous ventral spinal epidural hematomas are extremely rare in children and clinically recognized by the appearance of acute asymmetric focal motor and sensory involvement. In infants, the initial presenting symptoms are very non-specific and irritability is often the only initial manifestation. Appearance of other neurological signs may be delayed up to hours or even days later. In the absence of significant precipitating factors such as severe trauma or previously known coagulopathies,the diagnosis is usually delayed until the full picture of severe cord compression is developed. The diagnosis is finally made by performing magnetic resonance imaging. We report a 5-month-old infant with spinal epidural hematoma who presented with symmetrical upper limb weakness and diaphragmatic involvement to highlight the importance of recognizing the atypical manifestations for early diagnosis andintervention. References:1.

    Full Text Available BACKGROUND: Sciatica due to lumbar intervertebral disc herniation is one of the most common causes of radicular pain in an adult working population. This study aims at studying the effectiveness of conservative management of lumbar disc herniation as an alternative to surgical measures. METHODS: A prospective study of 100 patients with lumbar disc herniations who were treated conservatively were followed up at intervals of 1 month, 6 months and 1 year. Patients planned for conservative treatment were treated with pharmacological therapy, rest and physiotherapy. Those planned for epidural steroid injections were administered a single dose of steroid one level higher than the lesion in the epidural space. The collected data was analyzed by Chi square. RESULTS: Our results showed that in both genders, epidural steroid infiltration yielded better results than conservative treatment. Occupation had no discernible effect on the magnitude of disc herniation. People with sedentary lifestyle recovered better with epidural steroid infiltration as compared to the heavy physical labor group. Irrespective of disc bulge, protrusion or extrusion, the epidural steroid injection group showed significant improvement in symptoms as compared to conservative treatment. Smokers tended to show delay in the recovery as compared with the non-smoker group. The amount of disc herniation is not directly proportional to the outcome of treatment. CONCLUSIONS: Epidural steroid infiltration showed significant improvement in symptoms of lumbar intervertebral disc herniation thereby avoiding disc surgery. Conservative management for atleast 4 to 6 weeks can be recommended followed by epidural steroid in those patients without improvement. Cessation of smoking should be an integral part of the treatment.

    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.

    Epidural injections are commonly performed blindly in veterinary medicine. The aims of this study were to describe the lumbosacral ultrasonographic anatomy and to assess the feasibility of an ultrasound-guided epidural injection technique in dogs. A cross sectional anatomic atlas of the lumbosacral region and ex vivo ultrasound images were obtained in two cadavers to describe the ultrasound anatomy and to identify the landmarks. Sixteen normal weight canine cadavers were used to establish two variations of the technique for direct ultrasound-guided injection, using spinal needles or epidural catheters. The technique was finally performed in two normal weight cadavers, in two overweight cadavers and in five live dogs with radiographic abnormalities resulting of the lumbosacral spine. Contrast medium was injected and CT was used to assess the success of the injection. The anatomic landmarks to carry out the procedure were the seventh lumbar vertebra, the iliac wings, and the first sacral vertebra. The target for directing the needle was the trapezoid-shaped echogenic zone between the contiguous articular facets of the lumbosacral vertebral canal visualized in a parasagittal plane. The spinal needle or epidural catheter was inserted in a 45° craniodorsal-caudoventral direction through the subcutaneous tissue and the interarcuate ligament until reaching the epidural space. CT examination confirmed the presence of contrast medium in the epidural space in 25/25 dogs, although a variable contamination of the subarachnoid space was also noted. Findings indicated that this ultrasound-guided epidural injection technique is feasible for normal weight and overweight dogs, with and without radiographic abnormalities of the spine. PMID:25187175

    Full Text Available Introducción: La analgesia epidural se ha popularizado en España, tanto en su conocimiento como en su uso, a lo largo de los últimos 20 años. La elección de esta técnica analgésica por parte de la futura madre durante el trabajo de parto y el parto en Andalucía es un derecho de la mujer que, explícitamente, sólo estará limitado por sus condiciones físicas y de salud y por los recursos disponibles en el hospital en el momento del parto. Esta elección pone en relación 2 elementos: por un lado, el componente cognitivo que establece la conveniencia o no de utilizar esta técnica según los valores, percepciones, cultura, etc. de la mujer y, por otro, el componente conductual, es decir, el uso o no de la técnica en cuestión, que dependerá además de la elección de la mujer de las condiciones anteriormente mencionadas. Objetivo: Analizar qué características definen a las mujeres que, aun pudiendo, deciden no utilizar analgesia epidural durante el parto en Andalucía. Material y métodos: Para ello se ha utilizado la información proporcionada por las mujeres ingresadas por parto en los hospitales del Sistema Sanitario Público de Andalucía, contenida en las encuestas anuales de satisfacción de usuarios del sistema de atención hospitalario en esta comunidad autónoma entre los años 2000 y 2007. Con esta información se ha realizado un análisis de segmentación jerárquica que tenía por objetivo analizar el perfil de las mujeres que rechazan esta técnica analgésica. Resultados: Las principales características que definen a las mujeres que rechazan la analgesia epidural durante el parto vienen dadas por su nivel educativo, nivel de ingresos y situación laboral. Conclusiones: Las características sociales, económicas y culturales que definen el rechazo, es decir, el "tipo" de mujer que rehúsa la epidural, coinciden con el esquema de "mujer tradicional" estudiado por otros autores (que se caracteriza por tener escasos

Este cuadro suele ser reconocido como lumbalgia o lumbociática. En su forma clínica más común se observa mejoría rápida y solo presentan síntomas persistentes 5-10% de los casos (1. En la década de 1990 en EEUU, el sector salud registró costes estimados en miles de millones de dólares destinados al tratamiento del dolor lumbar, y teniendo en cuenta la tendencia a la búsqueda de una mayor expectativa de vida de la población, solo se puede esperar que los costes aumenten (2,3. El tratamiento comienza generalmente con medidas conservadoras, tales como medicación oral y terapia física, y puede incluir múltiples opciones intervencionistas invasivas para controlar el dolor. En ciertas ocasiones es necesario recurrir a cirugía para los pacientes que tienen déficit neurológico progresivo o para aquellos que están refractarios a otras terapéuticas. A veces el médico se encuentra frente a un dilema, después de una primera cirugía, con respecto a si se debería repetir la cirugía o intentar otra técnica alternativa. Este es el principal problema en el cual la liberación epidural de adherencias puede permitir "evitar cirugías".

    There is an interest in the use of high thoracic epidural anesthesia in cardiac surgery, because experimental and clinical studies have suggested that central neuroaxial blockade attenuates the response to surgical stress and improves myocardial metabolism and perioperative analgesia-thus enabling earlier extubation and a smoother postoperative course. Matters of major concern in the adoption of high thoracic epidural anesthesia in cardiac surgery are neurologic injury secondary to neuroaxial hematoma and hypotension secondary to sympatholysis. The risk associated with possible neuraxial hematoma caused by high thoracic epidural anesthesia has been thoroughly investigated and largely discounted, but scant attention has been devoted to the onset of hypotensive episodes in the same setting. We analyzed the hypotensive episodes that occurred in a series of 144 patients who underwent on-pump cardiac surgery procedures. Among the patient variables that we tested in a multivariate logistic-regression model, only female sex was found to be significantly correlated with hypotension. In order to decrease the incidence and severity of hypotensive episodes resulting from anesthetic blockade, anesthesiologists need to monitor, with special care, women patients who are under high thoracic epidural anesthesia. Further studies are needed in order to determine why women undergoing open heart surgery under high thoracic epidural anesthesia are at a relatively greater risk of hypotension. PMID:16878616

  18. Saline as the Sole Contrast Agent for Successful MRI-guided Epidural Injections

    International Nuclear Information System (INIS)

    Purpose. To assess the performance of sterile saline solution as the sole contrast agent for percutaneous magnetic resonance imaging (MRI)-guided epidural injections at 1.5 T. Methods. A retrospective analysis of two different techniques of MRI-guided epidural injections was performed with either gadolinium-enhanced saline solution or sterile saline solution for documentation of the epidural location of the needle tip. T1-weighted spoiled gradient echo (FLASH) images or T2-weighted single-shot turbo spin echo (HASTE) images visualized the test injectants. Methods were compared by technical success rate, image quality, table time, and rate of complications. Results. 105 MRI-guided epidural injections (12 of 105 with gadolinium-enhanced saline solution and 93 of 105 with sterile saline solution) were performed successfully and without complications. Visualization of sterile saline solution and gadolinium-enhanced saline solution was sufficient, good, or excellent in all 105 interventions. For either test injectant, quantitative image analysis demonstrated comparable high contrast-to-noise ratios of test injectants to adjacent body substances with reliable statistical significance levels (p < 0.001). The mean table time was 22 ± 9 min in the gadolinium-enhanced saline solution group and 22 ± 8 min in the saline solution group (p = 0.75). Conclusion. Sterile saline is suitable as the sole contrast agent for successful and safe percutaneous MRI-guided epidural drug delivery at 1.5 T.

    Full Text Available Background: Epidural application of morphine has been used for postoperative analgesia following spine surgery but short duration of action of single application limits its widespread use. Materials and Methods: One hundred and fifty patients undergoing lumbar laminectomy were randomly allocated to two groups of 75 patients each. Anesthetic technique was standardized in both the groups. In Group I, at the completion of laminectomy, a 5 × 1-cm strip of gelfoam soaked in 5 mg morphine (1 mg/ml was contoured to be placed in the epidural space whereas, in group II, gelfoam soaked in saline was placed in the epidural space and 5 mg morphine (1mg/ml was instilled over the intact epidural space. Analgesic consumption for 48 hours, time-of first analgesic request, time of ambulation, time of discharge from post anesthesia care unit (PACU and hospital and adverse effects were recorded. The data was analyzed using appropriate statistical tests. Results: Mean analgesic consumption in 48 hours was significantly less in group I (8.47 ± 3.674 mg as compared to group II (24.80 ± 6.009 mg. Supplemental analgesia was requested at 30.03 ± 6.796 hours in Group I, vs 10.25 ± 2.243 in group II (P 0.01. Conclusion: Epidural application of morphine soaked in gelfoam is an effective method for prolonging the postoperative analgesia after spine surgery.

    Background: Dexamethasone is a potent anti-inflammatory, analgesic, and antiemetic drug. Individual randomized controlled trials found a possible benefit of epidural dexamethasone. The purpose of this meta-analysis is to estimate the benefit of epidural dexamethasone on postoperative pain and opioid consumption and to formulate a recommendation for evidence-based practice. Materials and Methods: Prospective, randomized controlled trials comparing the analgesic efficacy of epidural local anesthetic and dexamethasone combination, with local anesthetic alone for postoperative pain management after abdominal surgery, were planned to be included in this meta-analysis. PubMed, PubMed Central, Scopus, and Central Register of Clinical Trials of the Cochrane Collaboration (CENTRAL) databases were searched for eligible controlled trials using the following search words: “Epidural”, “dexamethasone”, and “postoperative pain”, until February 20, 2015. Results: Data from five randomized control trials have been included in this meta-analysis. Epidural dexamethasone significantly decreased postoperative morphine consumption (mean difference −7.89 mg; 95% confidence interval [CI]: −11.66 to −3.71) and number of patients required postoperative rescue analgesic boluses (risk ratio: 0.51; 95% CI: 0.41-0.63). Conclusion: The present data shows that the addition of dexamethasone to local anesthetic in epidural is beneficial for postoperative pain management. PMID:27375389

    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

    Posterior fossa dural venous sinus thrombus is a well-described complication of head trauma, especially when fracture crosses the dural sinus grooves or in association with epidural hemorrhage. We have found that post-traumatic posterior fossa epidural hematoma compressing a dural venous sinus can mimic dural venous thrombus. To discuss the CT and MRI findings of posterior fossa epidural hemorrhages simulating sinus thrombosis, to make radiologists aware of this important imaging pitfall. We describe radiologic findings in four children in whom a posterior fossa epidural hemorrhage mimicked dural venous sinus thrombus. Routine CT head and CT venography were obtained on Toshiba volume and helical CT scanners. MRI and MR venography were performed on a Philips scanner. In all cases there was medial displacement and compression of the posterior fossa dural venous sinuses without intraluminal thrombosis. The epidural hemorrhage was seen tracking along sinus grooves in the occipital bone, peeling the dura containing the sinuses from the calvarium and compressing the sinus, simulating thrombosis on axial CT views. Both venous sinus thrombosis and posterior fossa epidural hemorrhages in children are well-described complications of head trauma. Posterior fossa epidural hemorrhage can mimic a sinus thrombus by compressing and displacing the sinuses. It is important to recognize this pitfall because treatment of a suspected thrombus with anticoagulation can worsen epidural hemorrhage. (orig.)

    el bloqueo neuromuscular producido por la d-tubocurarina ya está comprobada, pero sin embargo el mecanismo es controvertido. El objetivo del estudio fue el de evaluar la influencia de la procainamida en el bloqueo neuromuscular producido por el rocuronio e investigar los mecanismos de esa interacción. MÉTODO: Se utilizaron 15 ratones (250 a 300 g en preparación descrita por Bülbring. Se formaron los siguientes grupos (n = 5 cada: procainamida - 20 µg.mL-1 (Grupo I; rocuronio - 4 µg.mL-1 (Grupo II y rocuronio - 4µg.mL-1 y procainamida - 20µg.mL-1 (Grupo III. Se evaluó: 1 la amplitud de las contracciones musculares bajo la estimulación indirecta en cada grupo, antes y después de la adición de los fármacos; 2 los potenciales de placa terminal en miniatura (PPTM; 3 la eficacia de la 4-aminopiridina en la reversión del bloqueo neuromuscular. El mecanismo de la interacción se estudió en Biventer cervicis (n = 5 y diafragma de ratón desnervado (n = 5, observándose la influencia de la procainamida en la respuesta a la acetilcolina antes y después de la adición de la procainamida. RESULTADOS: De forma aislada, la procainamida no alteró las respuestas neuromusculares. El bloqueo producido con el Grupo III fue de 68,6% ± 7,1%, con una diferencia significativa (p = 0,0067 con relación al Grupo II (10,4% ± 4,5%, revertido por la 4-aminopiridina. La procainamida ocasionó un aumento en la frecuencia de los PPTM, seguido de bloqueo revertido por la 4-aminopiridina. En Biventer cervicis, la procainamida aumentó la respuesta a la acción de contracción de la acetilcolina, resultado no observado con el diafragma desnervado. CONCLUSIONES: La procainamida potenció el bloqueo producido por el rocuronio. Las alteraciones observadas con PPTM y Biventer cervicis identificaron una acción presináptica. El antagonismo de la 4-aminopiridina sobre el bloqueo de los PPTMs sugirió la desensibilización de los receptores por la procainamida.BACKGROUND AND OBJECTIVES

  8. Stereotactic Body Radiotherapy Reirradiation for Recurrent Epidural Spinal Metastases

    International Nuclear Information System (INIS)

    Purpose: When patients show progression after conventional fractionated radiation for spine metastasis, further radiation and surgery may not be options. Stereotactic body radiotherapy (SBRT) has been successfully used in treatment of the spine and may be applicable in these cases. We report the use of SBRT for 60 consecutive patients (81 lesions) who had radiological progressive spine metastasis with epidural involvement after previous radiation for spine metastasis. Methods and Materials: SBRT was used with fiducial and vertebral anatomy-based targeting. The radiation dose was prescribed based on the extent of spinal canal involvement; the dose was 8 Gy × 3 = 24 Gy when the tumor did not touch the spinal cord and 5 to 6 Gy x 5 = 25 to 30 Gy when the tumor abutted the cord. The cord surface received up to the prescription dose with no hot spots in the cord. Results: The median overall survival was 11 months, and the median progression-free survival was 9 months. Overall, 93% of patients had stable or improved disease while 7% of patients showed disease progression; 65% of patients had pain relief. There was no significant toxicity other than fatigue. Conclusions: SBRT is feasible and appears to be an effective treatment modality for reirradiation after conventional palliative radiation fails for spine metastasis patients.

    Background: Spinal hematomas are rare entities that can be the cause of an acute spinal cord compression syndrome. Therefore, an early diagnosis is of great importance. Patients and Methods: From 2001 to 2005 seven patients with intense back pain and/or acute progressive neurological deficit were studied via 1.5 T MRI (in axial and sagittal T1- and T2-weighted sequences). Follow-up MRI was obtained in six patients. Results: Four patients showed the MRI features of a hyperacute spinal hematoma (two spinal subdural hematoma [SSH] and two spinal epidural hematoma [SEH]), isointense to the spinal cord on T1- and hyperintense on T2-weighted sequences. One patient had an early subacute SEH manifest as heterogeneous signal intensity with areas of high signal intensity on T1- and T2-weighted images. Another patient had a late subacute SSH with high signal intensity on T1- and T2-weighted sequences. The final patient had a SEH in the late chronic phase being hypointense on T1- and T2-weighted sequences. Discussion: MRI is valuable in diagnosing the presence, location and extent of spinal hematomas. Hyperacute spinal hematoma and the differentiation between SSH and SEH are particular diagnostic challenges. In addition, MRI is an important tool in the follow-up in patients with conservative treatment.

    The occurrence of congenital neuroblastoma presenting at birth with symptoms of epidural compression secondary to spinal canal invasion is rare. Almost all cases reported in the literature have survived from the tumor but suffer severe sequelae, with the exception of the 2 most recently described whose birth was anticipated. The 3 cases of this article have been followed for a minimum of 5 years with the aim to describe their definitive late complications. In none of these cases had the routine ultrasound scan performed in third trimester of pregnancy discovered a tumor mass, nor had it shown abnormal fetal movements. All had leg hypotonia detected on the first day of life. In all, both primary and intraspinal tumors responded well to chemotherapy. All survive with motor deficit and severe bladder dysfunction despite early physiotherapy. Scoliosis has developed in the case with the longest follow-up. The description of these patients enforces the importance of early diagnosis of tumor masses in late pregnancy. Neonatologists should be aware of this rare clinical entity and take it into account in the differential diagnosis with other conditions of early-onset hypotonia. On the other hand, obstetric sonologists should be aware of the possibility to detect such rare tumors in late pregnancy, as anticipation of delivery may reduce the risk of late sequelae.

  12. Head trauma and CT with reference to epidural hematoma

    International Nuclear Information System (INIS)

    Computed tomography (CT) is useful to detect lesions in patients with mild head trauma in its acute stage which may be followed by a lucid interval of hours to several days before exact diagnosis is made, or in serious patients with impairment in state of consciousness. Non-enhanced scan can determine the location of the lesion in 94% of patients with brain tumor, and enhanced scan can do in more than 98%. CT can reveal many anatomical changes due to trauma. Of these pathological changes, epidural hematoma is often caused by the damage of the middle meningeal artery or its branch. Therefore, CT should be performed if a bone-fracture line runs across the meningeal artery. CT is also applicable for the patients with some brain symptoms such as those who had not immediate post-traumatic unconsciousness but have developed impairment in state of consciousness after a lucid interval, or those who have persistent headache even if they have no impairment in stage of consciousness. In CT findings, the margin of hematoma and normal cerebral tissues is usually clear in acute causes but unclear in subacute cases. (Ueda, J.)

  13. Spinal epidural abscess: correlation between MRI findings and outcome

    International Nuclear Information System (INIS)

    Our purpose was to determine if specific MRI findings in spinal epidural abscess (SEA), at the time of diagnosis, are associated with the clinical outcome. The clinical records and MRI studies of 18 patients with SEA were reviewed and follow-up was obtained from the outpatient medical record, telephone interview, or both. The association between findings on contrast-enhanced MRI and clinical outcome (weakness, neck or back pain, and incomplete functional recovery) was evaluated. With univariate analysis, narrowing of 50 % or more of the central spinal canal (P = 0.03), peripheral contrast-enhancement (P = 0.05), and abnormal spinal cord signal intensity (P = 0.05) were associated with weakness at follow-up. Persistent neck or back pain was associated with spinal canal narrowing (P = 0.02), peripheral contrast-enhancement (P = 0.02), and an abscess longer than 3 cm (P = 0.04) on MRI. Incomplete clinical recovery was associated with both abscess length (P = 0.01) and the severity of canal narrowing (P = 0.01). Abscess length, enhancement pattern, and severity of canal narrowing can be incorporated in a grading system that can be used to predict outcome. (orig.)

    Spinal epidural lipomatosis (SEL) results from an abnormal accumulation of unencapsulated fat within the epidural space and is a rare cause of spinal cord compression, which needs to be considered with a high index of suspicion. It most commonly occurs secondary to chronic corticosteroid use and endocrinopathies. Idiopathic cases are highly associated with obesity. We report an unusual case of idiopathic thoracic SEL in a 69-year-old male, with an adjacent infiltrative Hodgkin's lymphoma and associated vertebral crush fracture, which resulted in ataxia and sensory loss. Magnetic resonance imaging scans displayed extensive SEL and an infiltrative disease process causing thoracic cord compression. Surgical decompression confirmed the presence of extensive epidural lipomatosis and Hodgkin's lymphoma and subsequently led to improvement in neurological symptoms. To our knowledge, this is the first reported case of concomitant SEL with an adjacent Hodgkin's lymphoma resulting in cord compression. PMID:26962199

    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

    Spinal epidural haematoma (SEH) is a rare condition usually the result of bleeding of the epidural venous plexus that might present with acute spinal cord compression. It is often due to traumatic events, but 'spontaneous' cases have been described, usually related to different predisposing conditions, such as coagulopathies. A 47-year-old male presented with severe frontal headache and intense cervical pain which developed during a protracted breath-hold spearfishing session. A cervical spine MRI performed 12 days after symptom onset showed a small epidural blood collection on the left side of the spinal canal, at the C7-T1 level. One week later, blood was no longer present and the asymptomatic patient was discharged. Protracted minor trauma (neck flexion) and repeated Valsalva manoeuvres might have played a role in the genesis of this event. The role of decompression sickness is discussed as well. PMID:22828819

    A 61-year-old man presented via the emergency department with a few days history of abdominal and colic occlusion symptoms. He presented signs of sepsis, midline lumbar spine tenderness and reduced hip flexion. Computer tomography of the abdomen and pelvis showed a presacral collection contiguous with the posterior part of the colo-rectal anastomosis, and MRI lumbar spine revealed abscess invation into the epidural space. He underwent a laparotomy with washout of the presacral abscess and a colostomy with a prolonged course of intravenous antibiotic therapy. At 3 weeks after initial presentation he had made a full clinical recovery with progressive radiological resolution of the epidural abscess. The objective of the case report is to highlight a unique and clinically significant complication of a rare post-operative complication after rectal surgery and to briefly discuss other intra-abdominal sources of epidural abscess.

    Pyogenic haematogenous cervical epidural abscess complicated by tetraplegia is an uncommon entity, but its clinical importance overshadows its rarity. Predisposing risk factors for spinal epidural abscess include diabetes, intravenous drug abuse, liver disease, renal failure, malignancy, HIV, infection elsewhere, rheumatoid conditions, trauma and a number of spinal interventions. Lack of recovery and death are much more frequent when complete paralysis exists since more than 24 to 48 hours. Most authors combine decompressive laminectomy and antibiotics. Anterior decompression and needle aspiration are rarely used, the former more specifically in case of anterior abscess formation. A high index of suspicion along with reliance on gadolinium-enhanced MRI is essential to diagnose the pathology and institute appropriate treatment on an individual basis. The authors report on a diabetic male patient who developed a cervical epidural abscess with tetraplegia after dental extraction. He was treated within six hours by one stage anterior/posterior decompression and fusion, with complete recovery. PMID:21954768

    Full Text Available Coincidence of isolated testicular abscess and epidural-paravertebral abscess is a rare complication of brucellosis. A 24-year-old male patient was admitted to our clinic with 2 months ongoing back pain, night sweats and left scrotal pain. Septal cystic lesion with dense content in the left testis was considered to isolated testicular abscess in scrotal Doppler examination. Multiple spinal epidural and right paraspinal abscess were detected in the spinal magnetic resonance imaging. The patient was treated with drainage of abscess and oral antibiotics. The rare combination of spinal epidural and testicular abscess should be kept in the mind if a patient presented with low back pain and scrotal pain in regions where brucellosis was endemic.

    The thoracic epidural block is the most effective method of anesthesia in patients with a closed mechanical trauma of the chest. But this method is associated with a risk of damage of the spinal cord. So it can be used but by highly qualified specialists. The authors have worked out a method of anesthesia of the thoracic segments based on the phenomenon of hydrolock. It is more simple, safe, easy for any specialist able to use the technique of routine lumbar epidural block. PMID:12638497

Previous treatment included oral and topical medications as well as an intercostal nerve block; however, these treatment options did not provide significant relief. The patient was treated with a single-level T10 thoracic transforaminal epidural steroid injection for refractory postherpetic neuralgia. He reported complete resolution of his symptoms at 2- and 12-week follow-ups.

    Traumatic spinal epidural hematoma is uncommon in children, making rapid diagnosis difficult. In this report, we present a case of traumatic cervical epidural hematoma in a 1-year-old boy, diagnosed with computed tomography scanning and magnetic resonance imaging (MRI). Management was conservative and the lesion regressed spontaneously. The presentation in childhood is often nonspecific. MRI is the imaging modality of choice for diagnosing these lesions. Conservative treatment has to be considered in cases with a benign clinical course and provided that the patient is followed up neurologically with repeated MRI. PMID:27266638

    A 10-year-old boy presented with a 7-day history of back pain and pyrexia. MRI showed an epidural abscess arising from septic arthritis in a lumbar facet joint. To our knowledge, there are only two previously reported cases of septic arthritis of a facet joint leading to an epidural abscess. This case illustrates how infection in a synovial joint may extend into the extradural space and might be the route of infection in more cases than has previously been recognised. (orig.)

    Full Text Available Uno de los mayores obstáculos en la producción de embriones in vitro con fines de investigación básica, comerciales, o de conservación, es el detenimiento temprano del clivaje que ocurre de forma específica en una etapa del desarrollo. Para explicar este fenómeno se han postulado diferentes factores causales como: desórdenes en la cromatina, rearreglos del citoesqueleto, estrés oxidativo y daños mitocondriales. Esta última propuesta ha recibido gran atención, debido a que la mitocondria es fuente de especies reactivas de oxígeno (EROs y el estrés oxidativo es un mediador crítico de procesos fisiológicos y estados patológicos. Durante los últimos años se ha demostrado que el peróxido de hidrógeno (H2O2 es una molécula pivotante capaz de desencadenar muerte celular por diferentes mecanismos que pueden involucrar o no a los factores de transcripción: NFκB - p53, y es ejecutado por caspasas efectoras. Se cree que la mitocondria podría estar jugando un papel importante como productora o como blanco del H2O2, y como mediadora en la muerte por apoptosis de los embriones. El objetivo de esta revisión es mostrar el estado del arte en cuanto a la apoptosis desencadenada por estrés oxidativo y mediada por la mitocondria en los embriones bovinos producidos in vitro, como parte de la explicación del bloqueo del clivaje y la baja eficiencia que aún se tiene en este proceso.One of the biggest obstacles in the in vitro embryo production for basic research, commercial purposes, or conservation, is the blockade of the early cleavage, which occurs on a species-specific manner in a particular stage of development. To explain this phenomenon some causative factors have been postulated such as: disturbances in chromatin, cytoskeleton rearrangement, oxidative stress and mitochondrial damage. The latter has received considerable attention because mitochondrion is a source of reactive oxygen species (ROS, and oxidative stress is a critical

  15. The lucid interval associated with epidural bleeding: evolving understanding.

    Science.gov (United States)

    Ganz, Jeremy C

    2013-04-01

    The aim of this paper was to elucidate the evolution of our understanding of the term "lucid interval." A number of texts were reviewed to assess their suitability for analysis. The primary requirement was that the text contain detailed descriptions of a series of patients. Details of the clinical course, the findings and timing of surgery, and, when relevant, the time of death and postmortem findings were required. Books written by Henri-François Le Dran, Percival Pott, and James Hill fulfilled these criteria. Surgical findings included the presence and type of fractures, changes in the bone, separation of periosteum, malodorous or purulent material, tense brain, and hematoma. Postmortem findings supplemented and/or complemented the surgical findings. The courses of the patients were then tabulated, and the correlation between different clinical and operative findings was thereby determined. Our understanding of a lucid interval began in the early 18th century with the work of Henri-François Le Dran and Percival Pott in London. They did not, however, demonstrate an interval without symptoms between trauma and deterioration in patients with epidural hematomas (EDHs). The interval they described was longer than usually expected with EDHs and occurred exclusively in patients who had a posttraumatic infection. In 1751, James Hill, from Dumfries, Scotland, described the first hematoma-related lucid interval in a patient with a subdural hematoma. The first case of a lucid interval associated with an EDH was described by John Abernethy. In the 19th century, Jonathan Hutchinson and Walter Jacobson described the interval as it is known today, in cases of EDH. The most recent work on the topic came from studies in Cincinnati and Oslo, where it was demonstrated that bleeding can separate dura mater and that hemorrhage into the epidural space can be shunted out via the veins. This shunting could delay the accumulation of a hematoma and thus the rise in intracranial pressure

    Summary Vertebral osteomyelitis (or spondylodiscitis) is steadily increasing in Western countries and often results from hematogenous seeding, direct inoculation during spinal surgery, or contiguous spread from an infection in the adjacent soft tissue. We present the case of a 67-year-old white patient with type 2 diabetes who went to Hospital for high fever, back pain, and worsening of known infected ulcers in the left foot. Despite intravenous antibiotic treatment and surgical debridement of the foot infection, high fever and lower back pain continued. Bone biopsy and two consecutive blood cultures were positive for Staphylococcus aureus. A spinal magnetic resonance imaging (MRI) was performed, revealing serious osteomyelitis in L4 and L5 complicated by an epidural abscess. Contiguous or other distant focuses of infection were not identified. In this case, diabetic foot could be considered as a primary distant focus for vertebral osteomyelitis. Clinicians should consider vertebral osteomyelitis as a ‘possible’ diagnosis in patients with type 2 diabetes complicated by foot infection that is associated with fever and lower back pain. Learning points Vertebral osteomyelitis is increasing in Western countries, especially in patients with type 2 diabetes. The primary focus of infection is the genitourinary tract followed by skin, soft tissue, endocarditis, bursitis, septic arthritis, and intravascular access. Diabetic foot could be a rare primary focus of infection for vertebral osteomyelitis, and, however, vertebral osteomyelitis could be a serious, albeit rare, complication of diabetic foot. Clinicians should keep in mind the many potential complications of diabetic foot ulcerations and consider vertebral osteomyelitis as a “possible” diagnosis in patients with type 2 diabetes and foot ulcers associated with nonspecific symptoms such as lower back pain. Early diagnosis and correct management of vertebral osteomyelitis are crucial to improve clinical outcomes

    Full Text Available Background and Objective: There are various techniques to identify epidural space but superiority of one technique over other has not been adequately studied. We conducted a study to Compare and evaluate the three techniques for epidural space localization that is, loss of resistance (LOR syringe technique, balloon technique and drip infusion technique. Materials and Methods: Seventy-five patients of either sex, belonging to American Society of Anesthesiologists physical status Class 1 or 2, between 20 and 50 years of age, scheduled to undergo lower abdominal and lower limb surgeries were randomly allocated to one of the three groups (n = 25 each depending upon epidural space localization. In Group I, epidural space localization was done with LOR syringe technique. In Group II Balloon technique and in Group III drip infusion technique was used. Distance of the epidural space from skin, number of attempts, time taken for epidural space localization and quality of the block were the parameter recorded during the study. Results: First attempt success rate for epidural space localization was highest in Group III (100%. The mean time taken for epidural space localization was least in Group III, and when compared with other groups it was found to be statistically significant with P = 0.016. Number of attempt for space localization and success rate of the block was better in the majority of patients of Group III, but the difference was found to be statistically nonsignificant. Complication rate was almost negligible in all three techniques. Conclusion: We conclude that the time taken to localize the epidural space was least in drip infusion technique. As for number of attempts, quality of the block and complications is concerned, all the three techniques are comparable.

    We report on an acute epidural abscess in a 2-year-old boy, extending from the C1 level to the L5 level. The causative agent was Staphylococcus aureus as proved by pus and blood culture. The infectious source was in the scrotum. The diffuse epidural abscess was readily detected by MRI, which showed hypo-intensity in T1 WI and hyperintensity in gradient echo T2-weighted images. The abscess capsule was enhanced by Gadolinium-DTPA. The patient recovered completely after adequate treatment with antibiotics and follow up MRI showed complete disappearance of the epidural abscess. (orig.)

    The aim of the study was to compare in terms of patient comfort, surgical requirements and anaesthetic safety, the difference between epidural and general anaesthesia in patients undergoing surgery of the anal canal. The study was undertaken on 50 adult patients undergoing anal surgery. By random allocation 25 were given a general anaesthetic while 25 were given a low-dose epidural using 0.375% bupivacaine. Advantages and disadvantages of both methods were noted in the study. It was concluded that low-dose epidural is a more effective means of providing analgesia, while maintaining adequate sphincter tone for surgery on the anal canal, than general anaesthesia.

    Caudal epidural steroid injection is a very common intervention in treatment of low back pain and sciatica symptoms. Although extensively used, it is not devoid of complications. A few reports of chemical and infective arachnoiditis exist following lumbar epidural anaesthesia, but none following a caudal epidural steroid injection.We report a case of arachnoiditis following caudal epidural steroid injections for lumbar radiculopathy. The patient presented with contralateral sciatica, worsening low back pain and urinary retention few days following the injection, followed by worsening motor functions in L4/L5/S1 myotomes with resultant dense foot drop. Gadolinium-enhanced magnetic resonance imaging suggested infective arachnoiditis with diffuse enhancement and clumping of the nerve roots within the lumbar and sacral thecal sac. As the number of injections in the management of back pain and lumbo-sacral radicular pain is increasing annually, it is imperative to have a thorough understanding of this potentially dangerous complication and educate the patients appropriately.

    2009-01-01

    Objective: To investigate epidural fat distribution patterns in patients with lumbar intervertebral disc protrusion. Methods: Medical records were selected randomly from 30 patients whose diagnoses were consistent with the inclusion criteria of the study. Thickness of bilateral fat, the longest length of posterior fat, thickness of bilateral yellow ligament and thehernial distance of lumbar discs were measured by MRI at L3/L4, L4/L5 and LS/S 1 levels. According to clinical symptoms of lumbar intervertebral disc protrusion, the patients were divided into two groups at all space levels. All data were analyzed by statistical software. Results: The longest length of posterior epidural fat at the symptomatic levels was shorter than that at the non-symptomatic levels in each disc space. The symptomatic levels had no effect on the whole thickness of the lateral fat and lateral yellow ligaments. Conclusion: Epidural fat distribution in patients with lumbar intervertebral disc protrusion is different from that in normal adults. It is affected by the hernial distance of lumbar discs. The diagnostic criteria for spinal epidural lipomatosis in normal adults may therefore prove to be inappropriate for patients with lumbar intervertebral disc protrusion.

    Full Text Available Introduction. Use of analgesics is an evitable and necessary part of thoracic surgery. This study was designed to compare analgesic effects of persistent thoracic epidural anesthesia versus persistent intercostal nerve block and determine their role in opioid need after thoracotomy. Methods. 116 patients above 20 years old who were candidate for thoracotomy through either posterolateral or thoracoabdominal incision were situatedin one of three group for pain relief. For the first group, pain relieved by petidine and pentazosin. In 2nd group, pain relived by thoracic epidural anesthesia with bupivacaine catheters which were inserted between costal and plural space. In 3rd group, bupivacaine was introduced through 3rd and 4th intercostal space by catheter (2 mg/kg in devided doses. Pain was meseared by visual analogue scale and quantified by surgical residents through a method bupivacaine was injected. If Bupivacaine did not relieve pain, then opioid was used as adjuvant. Results. The study showed that epidural group needed less opioids and had more cooperation in comparison with two other group. The intercostal group complained of pain at chest tube site. Discussion. In thoracotomized patients, pain control is more effective via epidural anesthesia in turns of opioid side effects, expenses and patient comfort.

    2011-01-01

    Summary Lumbosacral epidural abscesses are managed either conservatively with IV antibiotics or with open surgery, particularly in the presence of acute neurological symptoms. Their location makes it difficult for image-guided interventional approaches either for biopsy or evacuation. We report the sacral hiatus and canal as a corridor for image-guided minimally invasive abscess of lumbosacral epidural abscess for aspiration. A 56-year-old man presented to the emergency department complaining of six weeks of worsening low back pain. MRI of the patient’s lumbosacral spine showed osteomyelitis involving his L5, S1 vertebrae, L5-S1 discitis, as well as an anterior epidural abscess extending from L4-5 disc space to the S2 vertebral level. Blood cultures grew out gram-positive cocci. For drainage, a 5-French micropuncture kit was utilized to access the hiatus. Under fluoroscopic guidance a microwire was then advanced along the sacral canal. An 18-gauge needle curved to approximate the contours of the sacral canal was then advanced over the guidewire. Once anatomic access was established 2 ml of thick purulent material was aspirated. The patient tolerated the procedure well, and no focal nerve root symptoms were noted following the procedure. Image-guided aspiration of lumbosacral epidural abscesses can thus be carried out in a safe and effective manner using a sacral hiatus approach. PMID:22192554

    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

    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. Conclusion Epidural analgesia with 1% lidocaine does not prolong the active-first and second stages of labor and does not increase vacuum-assisted or cesarean delivery rate.

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.

    Full Text Available Introducción: La analgesia epidural se ha popularizado en España, tanto en su conocimiento como en su uso, a lo largo de los últimos 20 años. La elección de esta técnica analgésica por parte de la futura madre durante el trabajo de parto y el parto en Andalucía es un derecho de la mujer que, explícitamente, sólo estará limitado por sus condiciones físicas y de salud y por los recursos disponibles en el hospital en el momento del parto. Esta elección pone en relación 2 elementos: por un lado, el componente cognitivo que establece la conveniencia o no de utilizar esta técnica según los valores, percepciones, cultura, etc. de la mujer y, por otro, el componente conductual, es decir, el uso o no de la técnica en cuestión, que dependerá además de la elección de la mujer de las condiciones anteriormente mencionadas. Objetivo: Analizar qué características definen a las mujeres que, aun pudiendo, deciden no utilizar analgesia epidural durante el parto en Andalucía. Material y métodos: Para ello se ha utilizado la información proporcionada por las mujeres ingresadas por parto en los hospitales del Sistema Sanitario Público de Andalucía, contenida en las encuestas anuales de satisfacción de usuarios del sistema de atención hospitalario en esta comunidad autónoma entre los años 2000 y 2007. Con esta información se ha realizado un análisis de segmentación jerárquica que tenía por objetivo analizar el perfil de las mujeres que rechazan esta técnica analgésica. Resultados: Las principales características que definen a las mujeres que rechazan la analgesia epidural durante el parto vienen dadas por su nivel educativo, nivel de ingresos y situación laboral. Conclusiones: Las características sociales, económicas y culturales que definen el rechazo, es decir, el "tipo" de mujer que rehúsa la epidural, coinciden con el esquema de "mujer tradicional" estudiado por otros autores (que se caracteriza por tener escasos

    Full Text Available Evaluamos el efecto del bloqueo de la expresión del receptor del factor de crecimiento semejante a la insulina tipo I (IGF-IR sobre el crecimiento in vivo de cáncer de mama empleando una estrategia "antisentido". Utilizamos el adenocarcinoma mamario murino progestágeno-dependiente C4HD. La administración intratumoral o sistémica de oligodeoxinucleótidos antisentido fosfotiolados al ARNm del IGF-IR (AS[S]ODN inhibió el crecimiento tumoral. El efecto antitumoral fue específico debido a su dosis-dependencia y a la falta de efecto en ratones tratados con el S[S]ODN "sentido". Los tumores obtenidos de ratones tratados con AS[S]ODN mostraron: disminución en la expresión de IGF-IR y en la fosforilación del sustrato del receptor de insulina-1, inhibición de la activación de PI-3K/Akt, p42/p44MAPK y ErbB-2, mientras que la expresión y activación del receptor de progesterona no se afectó. Es la primera demostración que el crecimiento de cáncer de mama puede ser inhibido por la administración in vivo de AS[S]ODN al IGF-IR.We addressed the effect of targeting type I insulin-like growth factor receptor (IGF-IR, with antisense strategies in in vivo growth of breast cancer cells. We used C4HD tumors from an experimental model of hormonal carcinogenesis in which medroxyprogesterone acetate induced mammary adenocarcinomas in Balb/c mice. Intratumor or systemic administration of phosphorothiolated antisense oligodeoxynucleotides (AS[S]ODN to IGF-IR mRNA resulted in a significant inhibition of C4HD tumor growth. The antitumor effect was specific since inhibition of tumor growth was dose-dependent and no effect was observed in mice treated with sense S[S]ODN. Tumors from AS[S]ODN-treated mice showed a decrease in IGF-IR expression and in insulin receptor substrate-1 tyrosine phosphorylation. Activation of PI-3K/Akt, p42/p44 MAPK and ErbB-2 was abolished in tumors treated with AS[S]ODN. Progesterone receptor expression or activity remained

  5. A child case of spinal epidural abscess with successful conservative treatment following early diagnosis by CT and 67Ga SPECT

    International Nuclear Information System (INIS)

    Although early diagnosis and treatment of spinal epidural abscess are emphasized in children in view of its prognosis, these are very difficult because of the nonspecific symptoms of the disease. A 6-year-old boy complained of lumbar pain and difficulty in walking. Computed tomography, performed 6 days after the occurrence of complaints, revealed space occupying lesion in the spinal canal and epidural space at the level of L2-S1. Subsequent single photon emission computed tomography (SPECT) with Ga-67 clearly visualized active inflammation resulting from epidural abscess. The patient received intensive chemotherapy alone. Twenty-one days later, Ga-67 uptake disappeared on SPECT images. The finding indicates the usefulness of diagnostic imagings in the early diagnosis and treatment of spinal epidural abscess, thus avoiding surgery, the role of which has been under debate.

    Full Text Available There are many studies about epidural fibrosis after surgical manipulation of the spine. We have studied formation of the post laminectomy epidural fibrosis after application of two materials (Silicone and Teflon in this report. This expriment is on two groups of rats. Two separated laminectomies were done in each rat, one serving as control while in the other laminectomy spaces Silicone was used in group A and Teflon in group B. Laminectomy spaces were evaluated with gross dissection and histologic studies after 6 weeks. Silicone decreased intermuscular scar, deep scar, dural adhesion and collagen fiber density in epidural space. Teflon decreased dural adhesion and collagen fiber density but did not decrease intermuscular and deep scar formation in epidural space.

    under epidural (n = 386) or general (n = 499) anesthesia. Thirty-day mortality (3.4% for epidural anesthesia versus 4.4% general anesthesia; P = 0.414) and comorbidity were comparable in the 2 groups. Graft occlusion within 7 days after surgery was reported in 93 patients, with a similar incidence in...... the epidural (10.1%) and general (10.8%) anesthesia groups (P = 0.730). When examining a subgroup of patients (n = 242) exposed to surgery on smaller vessels (femorodistal in situ bypass procedures, n = 253), the incidence of graft occlusion was also similar in the 2 groups at 14.0% and 9.......4%, respectively (P = 0.262). CONCLUSION: This retrospective study has shown that when graft patency is evaluated 7 days after surgery, anesthetic choice (epidural or general anesthesia) does not influence outcome....

An independent pain management team scoring technical success found epidural technique to be consistent. Oncological outcome was an endpoint of our study, comparing both analysis groups. We classed prostate-specific antigen (PSA recurrence after RRP as a serum PSA ≥ 0.2 ng/mL at any stage of postoperative follow-up. Complications were recorded to 30 days using the modified Clavien system, and full statistical analyses were undertaken.Results: Records were available for 239 men; we observed a decreased trend in the use of epidural for pain management, along with a decrease in average hospital stay and an overall epidural success rate of 64%. When dividing data into RRP with and without epidural, we found a median hospital stay of 7 days for patients receiving an epidural compared with 6 days for those not receiving an epidural. The differences were statistically significant (P < 0.048 and remained so after adjusting for complications (P < 0.0001. Regarding oncological outcome, PSA recurrence was further analyzed in this cohort. Percentage of recurrence was higher (14.8% for patients receiving an epidural than for the non-epidural group (4.8%.

    Phantom limb pain may appear in up to 85% of patients after amputation. There is no effective treatment. Perioperative epidural infusion of morphine and bupivacaine, alone or in combination, is effective in preventing phantom limb pain in patients with pre-existing limb pain. Serious side-effects, however, make them difficult to manage on a general ward. Clonidine has been shown to be an effective postoperative analgesia when applied epidurally. To mitigate the potentially serious side-effect...

    Full Text Available Background: Opioids are considered mainstream for combined spinal-epidural anesthesia, but frequently limited by adverse effects. The aim of this study was to examine whether low-dose spinal neostigmine, epidural dexamethasone or their combination enhances analgesia from spinal bupivacaine without adverse effects. Materials and Methods : A total of 60 patients undergoing orthopedic surgery were randomized to one of four groups and evaluated for 24-h after surgery for analgesia (time to first rescue analgesic and rescue analgesic consumption. Patients received 15 mg bupivacaine plus the test drug intrathecally (saline or 1 microgram (μg neostigmine. The epidural test drug was either saline or 10 mg dexamethasone. The Control group (CG received spinal and epidural saline. The Neostigmine group (NG, spinal neostigmine and epidural saline; the Dexamethasone group (DG, spinal saline and epidural dexamethasone; and the Neostigmine-dexamethasone group (NDG, spinal neostigmine and epidural dexamethasone. Results: The CG (282 ± 163 min and NG (524 ± 142 min were similar in their times to first rescue analgesic and analgesic consumption. The time to first rescue analgesic was longer for the DG (966 ± 397 min compared with CG and NG (P < 0.0002, and the DG had less ketoprofen consumption and lower overall visual analogue scale-pain sores compared with CG and NG (P < 0.0005. Addition of 1 mg-neostigmine (NDG resulted in longer time to rescue analgesic (1205 ± 303 min; P < 0.02 and lower ketoprofen consumption (P < 0.05 compared to DG. Sporadic cases of vesical catheterization and emesis were observed, however adverse effects were similar among groups. Conclusion: Spinal 1 microgram (μg neostigmine further enhanced analgesia from spinal bupivacaine combined with epidural dexamethasone, without increasing the incidence of adverse effects.
