RESUMEN

El dolor es una causa importante de sufrimiento físico y emocional. El tratamiento médico de los pacientes con dolor crónico refractario es un gran reto. Se presenta el caso de una paciente de 19 años con un cuadro radicular compresivo secundario a Hernia discal L5-S1 derecha, que se le aplicó una discectomía L5-S1 por técnica de Caspar. Al mes de evolución regresa con igual sintomatología. A pesar de múltiples terapias farmacológicas y procederes intervencionistas, el dolor neuropático no mejora, después de múltiples estudios y discusiones en colectivo se determina la posibilidad de la colocación de un neuroestimulador medular, proceder que se lleva a cabo con mejoría considerable de su cuadro doloroso(AU)

Pain is a major cause of physical and emotional suffering. The management of patients with refractory chronic pain is a great challenge. The case is presented of a 19-year-old female patient with compressive radicular symptoms secondary to right L5-S1 disc herniation, who underwent L5-S1 discectomy with Caspar technique. After one month of evolution, she returned with the same symptoms. Despite multiple pharmacological therapies and interventional procedures, the neuropathic pain did not improve. After multiple studies and collective discussions, the possibility of placing a spinal neurostimulator was decided. After the procedure, the patient improved considerably with respect to her painful symptoms(AU)

RESUMEN

BACKGROUND: Intermittent intraoperative neuromonitoring of the recurrent laryngeal nerve is the ideal complement in thyroid surgeries, decreasing thyroid injuries. OBJECTIVE: To analyze the prevalence of recurrent laryngeal nerve injuries with the use and without the use of neuromonitoring in thyroid surgery. METHOD: Observational, descriptive and retrospective study, in which a total of 571 patients were included between the years 2012-2018. Of which 180 neuromonitoring was used and 391 were not used. RESULTS: Of the 180 patients who underwent total thyroidectomy with the use of neuromonitoring, we had a total of 8 (4.4%) transient paralysis and 2 (1.1%) definitive. Without the use of neuromonitoring we obtain 12 (3%) transient paralysis and 7 (1.85%) definitive. CONCLUSIONS: We believe that the use of neuromonitoring complementary to surgery should be used routinely to the usual technique. And we also obtain significant results regarding the reduction of recurrent laryngeal nerve injuries with the use of intraoperative neuromonitoring.

ANTECEDENTES: La neuromonitorización intraoperatoria intermitente del nervio laríngeo recurrente es el complemento ideal en las cirugías tiroideas, ya que disminuye las lesiones. OBJETIVO: Analizar la prevalencia de lesiones del nervio laríngeo recurrente con y sin el uso de neuromonitorización en cirugía de tiroides. MÉTODO: Estudio observacional, descriptivo y retrospectivo, en el que se incluyeron 571 pacientes entre los años 2012 y 2018. De ellos, en 180 se utilizó neuromonitorización y en 391 no. RESULTADOS: De los 180 pacientes que se sometieron a tiroidectomía total con neuromonitorización hubo 8 (4.4%) parálisis transitorias y 2 (1.1%) parálisis definitivas. Sin el uso de neuromonitorización hubo 12 (3%) parálisis transitorias y 7 (1.85%) definitivas. CONCLUSIONES: Creemos que la neuromonitorización debe usarse sistemáticamente con la técnica habitual. Obtenemos resultados significativos con respecto a la reducción de las lesiones del nervio laríngeo recurrente con el uso de neuromonitorización intraoperatoria.

RESUMEN

A anestesia locorregional reduz o requerimento de agentes inalatórios e diminui as respostas autonômicas a estímulos cirúrgicos nocivos. Objetiva-se descrever um bloqueio anestésico do plexo braquial guiado por neuroestimulador em jumento, submetido à amputação do membro anterior direito. Foi realizada medicação pré-anestésica com detomidina 0,01mg.kg-1, indução com diazepam 0,05mg.kg-1 e cetamina 2mg.kg-1, todos pela via intravenosa (IV), e a manutenção da anestesia com isoflurano. O plexo braquial foi bloqueado por acesso subescapular, sendo usado neuroestimulador. Utilizou-se 1mg.kg-1 de bupivacaína 0,5% sem vasoconstritor, associada a 1mg.kg-1 de lidocaína 2% sem vasoconstrictor. Os valores de FC e ƒ durante o procedimento cirúrgico variaram de 62 a 78bpm e de 24 a 32rpm, respectivamente. Foram coletadas quatro amostras de sangue para dosagem de cortisol. Este, antes da aplicação da medicação pré-anestésica, foi de 6,4µg/dL e, 30 minutos após a MPA, foi de 2,8µg/dL. A recuperação anestésica foi rápida e sem complicações. O bloqueio do plexo braquial guiado por neuroestimulador mostrou-se eficaz em jumentos, fornecendo analgesia e anestesia satisfatória.(AU)

Locoregional anesthesia reduces the requirement for inhaled agents and reduces the autonomic responses to noxious surgical stimuli. The aim of this study was to describe an anesthetic block of the brachial plexus guided by a neurostimulator in a donkey submitted to right limb amputation. Preanesthetic medication was performed with detomidine 0.01mg.kg-1 induction with diazepam 0.05mg.kg-1 and ketamine 2mg.kg-1 all intravenously, and maintenance of anesthesia with isoflurane. The brachial plexus was blocked by subscapular access, using a neurostimulator. For this purpose, 1mg.kg -1 of bupivacaine 0.5%, without vasoconstrictor, and 1mg.kg- 1 of lidocaine 2%, without vasoconstrictor were used. The values of HR and ƒ during the surgical procedure ranged from 62 to 78bpm, and 24 to 32bpm, respectively. Four blood samples were collected for cortisol dosing. This, prior to the application of the pre-anesthetic medication was 6.4µg/dL and 30 minutes was 2.8µg/dL. Anesthesia recovery was rapid and uncomplicated. Neurostimulator-guided brachial plexus blockade proved to be effective in donkeys, providing satisfactory analgesia and anesthesia.(AU)

RESUMEN

INTRODUCCIÓN: La anestesia del plexo braquial por vía axilar es un proceder frecuentemente empleado para la cirugía del miembro superior; disponer de un neuroestimulador para identificar las estructuras a bloquear ofrece múltiples ventajas. OBJETIVOS: Evaluar la efectividad del bloqueo por esta vía utilizando el neuroestimulador KWD 80811. MATERIAL Y MÉTODO: Se realizó un estudio descriptivo longitudinal y prospectivo en 100 pacientes adultos, de uno u otro sexo, ASA I-III, programados para cirugía de la mano, antebrazo y tercio inferior del brazo, en el Hospital Universitario¼ Dr. Carlos J. Finlay¼ en el período comprendido entre enero-septiembre de 2008. El neuroestimulador KWD 80811 fue empleado para la detección del plexo braquial, y la técnica utilizada para el bloqueo fue la perivascular de Burnham. Como anestésico local se empleó lidocaína al 1 %(7 mg por kg de peso) asociado con adrenalina 1:200 000. RESULTADOS: Se registró período de latencia media de 19.2 min., la calidad de la analgesia quirúrgica fue excelente en el 93 % de los casos y mala en 1 %. Reportamos una sola complicación sin interferencia con el proceder ni secuelas para el paciente. CONCLUSIONES: Esta técnica constituye una alternativa con elevada eficacia, confortable para el paciente y con muy bajo índice de complicaciones.

Introduction: Anesthesia of brachial plexus by axillary route is a frequent surgical procedure for upper extremity; availability of a neurostimulator to identify structures to be blockaded offer many advantages. Objectives: To assess the effectiveness of blockade by this route using the KWD90811 neurostimulator. Material and Methods: A prospective, longitudinal and descriptive study was conducted in 100 adult patients of both sexes, ASA I-III programmed for hand, forearm and inferior third of the arm surgery in "Dr. Carlos J. Finlay" University Hospital from January to September, 2008. Above mentioned neurostimulator was used to detect of brachial plexus and the technique used for blockade was the Burnham's perivascular one. As local anesthesia 1% lidocaine was used (7 mg /kg/bw) associated with adrenaline 1: 200.000. Results: There was an average latency period of 19.2 min; quality of surgical anesthesia was excellent in 93% of cases and poor in 1% with an only one complication without interference in the procedure and sequelae for patient. Conclusions: This technique is a high performance alternative suitable for patient and with a very low rate of complications.
