Analgesia con bloqueo TAP y bomba elastomérica en la reparación de hernias ventrales (primarias e incisionales) abdominales por laparoscopia en régimen de cirugía mayor ambulatoria / Analgesia with TAP block and elastomeric pump in the repair of ventral (primary and incisional) abdominal hernias by laparoscopy in major outpatient surgery

Antecedentes: El dolor moderado severo es una limitación para la incorporación de procedimientos en cirugía mayor ambulatoria (CMA), siendo uno de los principales motivos de reingreso o consulta a urgencias en las primeras horas del postoperatorio. Representa un indicador de calidad para las unidades de CMA. Algún estudio ya mide la eficacia de las bombas elastoméricas en el domicilio en CMA, pero no para la reparación de eventración de línea media por laparoscopia. Objetivo: Se diseñó un estudio para medir el dolor postoperatorio en la reparación de hernias ventrales, primarias o incisionales, de línea media por vía laparoscópica (malla fijada con tackers y cola de cianocrialato) con un diámetro transverso inferior a los 8 centímetros, en pacientes ASA I-II. Se valoró la viabilidad de la utilización de las bombas elastoméricas, con infusión continua de antinfl amatorio, opiáceos débiles y antieméticos en el domicilio del paciente. Pacientes y métodos: Estudio prospectivo observacional en pacientes ASA I-II, intervenidos de reparación de hernia ventral por laparoscopia, bajo una estrategia de control de dolor multimodal. Se realizó anestesia general endovenosa, con propofol y remifentanilo, junto a perfusión de lidocaína, y bloqueo TAP ecoguiado con levobupivacaína y mepivacaína con punción bilateral. Se inició la analgesia endovenosa intraoperatoriamente y para domicilio se pautó bomba elastomérica con dexketoprofeno, tramadol y ondansetrón, que se inció en la zona de recuperación postanestésica, junto a paracetamol fi jo y metamizol de rescate. La enfermería integrante de la unidad de hospitalización a domicilio se encargó del control postoperatorio en el domicilio del paciente. Se midió a las 24 h y 48 h el dolor postoperatorio a través de las escalas EVA y Andersen, además de las complicaciones que hubieran surgido (disfunción del dispositivo, náuseas/vómitos, complicaciones quirúrgicas)...(AU)

Background: Severe moderate pain is a limitation for the incorporation of procedures in major ambulatory surgery (MOS), being one of the main reasons for readmission or consultation to the emergency department in the first postoperative hours. It represents a quality indicator for AMC units. Some studies have already measured the efficacy of elastomeric pumps in the home in the AMC, but not for laparoscopic repair of midline eventration. Objective: A study was designed to measure postoperative pain in the repair of ventral, primary or incisional, midline hernias by laparoscopy (mesh fixed withtackers and cyanocryalate glue) with a transverse diameter of less than 8 centimeters, in ASA I-II patients. The feasibility of using elastomeric pumps withcontinuous infusion of anti-inflammatory drugs, weak opioids and antiemetics at the patient’s home was assessed. Patients and methods: Prospective observational study in ASA I-II patients who underwent laparoscopic ventral hernia repair under a multimodal pain control strategy. Intravenous general anesthesia was performed with propofol and remifentanil, together with lidocaine perfusion, and ultrasound-guided TAP block with levobupivacaine and mepivacaine with bilateral puncture. Intravenous analgesia was started intraoperatively and an elastomeric pump with dexketoprofen, tramadoland ondansetron was prescribed for home use, which was started in the postanesthetic recovery area, together with fixed paracetamol and rescue metamizole. The nursing staff of the home hospitalization unit was in charge of postoperative monitoring at the patient’s home. Postoperative pain was measured at 24 h and 48 h using the VAS and Andersen scales, as well as any complications that might have arisen (device dysfunction, nausea/vomiting, surgical complications). Patient satisfaction was measured by means of a survey at 30 days, during the postoperative follow-up with the surgeon.(AU)

Actualización en analgesia preventiva y analgesia multimodal / Update on preventive analgesia and multimodal analgesia

Una deficiente calidad del manejo del dolor post operatorio agudo genera aumento en la morbilidad perioperatoria, disminuye la calidad de vida del paciente, aumenta los reingresos hospitalarios y, finalmente, los costes en salud. La analgesia preventiva y multimodal son dos estrategias que han sido implementadas para tratar de optimizar el manejo del dolor. Si bien en la primera, la evidencia es favorable a su empleo, aún no existe un total consenso en esto. A su vez, la analgesia multimodal, al emplear diferentes fármacos y/o técnicas, ha logrado evidenciar de mejor manera su utilidad y los beneficios al implementarla como terapia. En este artículo, revisamos la evidencia que certifica y avala el uso de éstas. Finalmente, a nuestro parecer, lo más importante en el quehacer del clínico, es lograr individualizar la estrategia que usaremos en el manejo del dolor postoperatorio, adaptándonos a las necesidades y el contexto propio de cada uno de nuestros pacientes.

A poor quality of acute postoperative pain management generates an increase in perioperative morbidity, decreases the quality of life of the patient, increases hospital readmissions and finally, increases health costs. Preventive and multimodal analgesia are two strategies that are implemented to try to optimize pain management. Although in the first, the evidence is favorable to its use, there is still no total consensus. At the same time, multimodal analgesia, by using different drugs and/or techniques, has demonstrated, in a better way, its usefulness and benefits when implemented as a therapy. In this article, we review the evidence that certifies and supports the use of these techniques. Finally, in our opinion, the most important thing in the clinician's task is to be able to individualize the strategy that we will use in postoperative pain management, adapting to the needs and context of each one of our patients.

Eficacia de la analgesia peridural continua con bupivacaína y fentanilo en la cirugía de colon / Efficacy of continuous peridural analgesia with bupivacaine and fentanyl in colon surgery

Introducción: En la cirugía de colon se persigue lograr una recuperación acelerada y se debate el método analgésico más ventajoso. Objetivo: Comparar la eficacia analgésica de la infusión continua peridural con bupivacaína y fentanilo frente a la analgesia parenteral en este tipo de intervención. Métodos: Se realizó un estudio cuasi-experimental, prospectivo y longitudinal, en 30 pacientes operados de colon entre agosto 2018 agosto 2019 en el Hospital Militar Central Dr. Carlos J. Finlay; divididos de forma no aleatoria en grupo analgesia peridural y grupo analgesia multimodal endovenosa. Resultados: La demora en despertar y extubar en el grupo peridural fue inferior (1,6-1,8 min) a los 4,9-5,0 min en el multimodal, igual ocurrió con la estadía en Unidad Cuidados Intensivos Quirúrgicos y hospitalaria aunque con discreta diferencia. El 60 por ciento de los pacientes en el grupo peridural presentaron ruidos hidroaéreos en las primeras 24 h y el 80 por ciento expulsó gases a las 48 h o antes, con marcada diferencia del multimodal. La analgesia fue buena en ambos grupos, valores de escala visual análoga inferiores en el grupo peridural, solo el 13,3 por ciento necesitó dosis rescate frente al 26,7 por ciento en el multimodal. Las complicaciones más frecuentes fueron hipotensión (23,3 por ciento) y bradicardia (10 por ciento), sin diferencias entre grupos. La analgesia aceleró la recuperación en el 87,5 por ciento de los casos en el grupo peridural superior al 76 por ciento del grupo multimodal. Conclusiones: La analgesia peridural continua con bupivacaína y fentanilo es más eficaz que la analgesia multimodal endovenosa en la cirugía de colon y acelera la recuperación posoperatoria(AU)

Introduction: In colon surgery, accelerated recovery is pursued and the most advantageous analgesic method is still under debate. Objective: To compare the analgesic efficacy of continuous epidural infusion with bupivacaine and fentanyl versus parenteral analgesia in this type of operation. Methods: A quasiexperimental, prospective and longitudinal study was carried out with thirty patients who underwent colon surgery, between August 2018 and August 2019 at Dr. Carlos J. Finlay Central Military Hospital, nonrandomly divided into an epidural analgesia group and a multimodal intravenous analgesia group. Results: The awakening and extubation time in the epidural group was lower (1.6 -1.8 min) than the 4.9 to 5.0 min for the multimodal group. The same happened with intensive care unit and hospital stay, although with a discrete difference. 60 percent of the patients from the epidural group presented hydroaerial noise within the first 24 hours and 80 percent expelled gasses at 48 hours or earlier, with a marked difference in the multimodal group. Analgesia was good in both groups, with lower visual analog scale values in the peridural group; only 13.3 percent required rescue doses compared to 26.7 percent in the multimodal group. The most frequent complications were hypotension (23.3 percent ) and bradycardia (10 percent ), without differences between groups. Analgesia accelerated recovery for 87.5 percent of cases in the epidural group, compared to 76 percent in the multimodal group. Conclusions: Continuous epidural analgesia with bupivacaine and fentanyl is more effective than multimodal intravenous analgesia in colon surgery and accelerates postoperative recovery(AU)

Erector Spinae Plane Block in pediatric cancer pain: Case report / Bloqueo del plano erector espinal en dolor oncológico pediátrico: reporte de caso

Abstract The advent of the erector spinae plane block brought a new therapeutic option in a multimodal analgesia strategy, as evidenced in this case, which describes a five-year old pre-school patient who presented with severe abdominal cancer pain, secondary to an abdominal neuroblastoma, with partial high-dose opioid response, undergoing bilateral erector spinal plane block. The technique used did not give rise to complications and proved to be effective in blocking pain and reducing the opioid dosage 36 hours after the procedure. The paper discusses the variables involved in the administration mode (continuous infusion vs. bolus) and the benefit for optimal analgesia in the pediatric oncology setting.

Resumen Con la aparición del bloqueo del plano erector espinal surgen nuevas alternativas terapéuticas dentro de una estrategia de analgesia multimodal, tal como se puede apreciar en este caso, en el cual se describe un paciente preescolar de cinco años, quien cursó con dolor abdominal oncológico intenso secundario a neuroblastoma abdominal con respuesta parcial a opioides en dosis altas y en el que se empleó el bloqueo mencionado aplicado bilateralmente. La técnica empleada no generó complicaciones y demostró ser efectiva al permitir el control del dolor y la disminución de las dosis de opioides en las 36 horas posteriores a su colocación. Se plantea la discusión de variables con relación a la forma de administración (infusión continua vs. bolo) y la utilidad en la optimización analgésica en el contexto oncológico pediátrico.

Aplicación de la técnica OFA en cirugía mayor. Experiencia en un hospital secundario / OFA in major surgery. Experience at a secondary level hospital

Introducción: La técnica OFA (opioid free anaesthesia) se basa en una anestesia multimodal con menor uso de opioides, que consigue un adecuado control del dolor, con menor incidencias de náuseas y vómitos en el postoperatorio y mejora el pronóstico en los pacientes oncológicos.Pacientes y método:Estudio retrospectivo de casos de pacientes sometidos a cirugía mayor en el periodo de noviembre de 2018 a febrero de 2020. Objetivo principal: cuantificar tipo y dosis de opioide administrado en periodo intraoperatorio y en el postoperatorio inmediato. Objetivos secundarios: graduación del dolor en el postoperatorio y al alta a planta de hospitalización y presencia de náuseas/vómitos en el postoperatorio. Resultados: 157 pacientes fueron incluidos. El 29,9 % de los pacientes no precisaron ninguna dosis de opioide intraoperatorio. De los que sí la precisaron, un 72,7 % de los mismos solo necesitó morfina y a una dosis media de 3,3 mg (± 0,9); un 8,1 % solo recibieron fentanilo (dosis media de 110,1 mcg, ± 57,1), y un 19,2 % recibieron morfina y fentanilo (3,8 mg ± 1,2 y 90,4 mcg ± 62,4, respectivamente). En cuanto a la necesidad de opioide postoperatorio, solo el 31,7 % de los pacientes precisó su administración; de ellos ⅔ (33 pacientes) solo recibieron morfina (4,8 mg ± 2,6), 1/5 (10 pacientes) solo fentanilo (83,3 mcg ± 28,8) y el resto una combinación de fentanilo y morfina (140,6 mcg ± 119,4 y 8 mg ± 5,9, respectivamente).Respecto a la intensidad de dolor, el valor en la escala EVA a la llegada de los pacientes a la Reanimación tuvo un valor de 1,6 ± 1,9 y al alta de 0,3 ± 0,6. Solo dos pacientes tuvieron náuseas o vómitos.Conclusiones:El uso de una técnica OFA es factible en cirugía mayor y permite un adecuado control del dolor. La necesidad de opioides intravenosos, tanto en el intraoperatorio como en el postoperatorio, es menor cuando se realiza una técnica OFA.(AU)

Introduction: Opioid free anaesthesia is a new paradigm that focuses in multimodal analgesia with an opioid sparing approach that provides a good pain management, without nauseas nor vomiting and improves prognosis in oncological patients. Patients and method: Cases retrospective study of major surgery patients from november 2018 to february 2020. Main objective: type and dosage of opioid requeriments both in the intraoperatory and postoperative setting. Secondary objectives: pain level score cuantification at the end of the surgery and at leaving the postoperative recovery unit and incidence of nausea/vomiting. Results:157 patients were recruited. 29,9 % need no opioid intraoperatively. Those who requiered it, 72,7 % only needed morphine (3,3 mg ± 0,9), 8,1 % had to recieved fentanyl (110,1 mcg, ± 57,1) and 19,2 % need both morphine and fentanyl (3,8 mg ± 1,2 and 90,4 mcg ± 62,4). At the postoperative recovery unit, only 31,7 % precised opioids: ⅔ (33 patients) recieved morphine (4,8 mg ± 2,6), 1/5 (10 patients) only fentanyl (83,3 mcg ± 28,8) and the rest needed a combination of fentanyl and morphine (140,6 mcg ± 119,4 and 8 mg ± 5,9, respectively). Two of them have nausea or vomyting.Conclusions:An opioid free anaesthesia approach is feasible in major surgery patients and it achieves and adequate pain management. Opioid requeriments in such patients is less than in those who recieved a traditional base opioid analgesia protocol.(AU)

Intravenous lidocaine infusion for the treatment of acute pain in the pediatric intensive care unit: case series / Infusión de lidocaína endovenosa para el tratamiento de dolor agudo en la unidad de cuidado intensivo pediátrico: serie de casos

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

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

Eficacia terapéutica de la buprenorfina para tratamiento de dolor agudo postoperatorio en cirugía torácica por toracoscopía / Therapeutic efficacy of buprenorphine for treatment of acute postoperative pain in thoracic surgery by thoracoscopy

Resumen: Introducción: El dolor postoperatorio en toracoscopía tiene una incidencia del 80%. Estos procedimientos se realizan bajo anestesia general o sedoanalgesia. La buprenorfina en dosis de 4 μg/kg o más es un fármaco pilar para el tratamiento de dolor postoperatorio; sin embargo, dosis menores pueden ser suficientes. El objetivo de este estudio fue demostrar que dosis de 1-3 μg/kg de buprenorfina aporta una adecuada analgesia con menores efectos adversos durante el postoperatorio en pacientes sometidos a cirugía toracoscópica. Material y métodos: Se realizó el estudio prospectivo, transversal y doble ciego en 48 pacientes sometidos a toracoscopía, divididos en 3 grupos: A (1 μg/kg), B (2 μg/kg) y C (3 μg/kg) tratados con buprenorfina, se evaluaron efectos adversos, intensidad de dolor por escala verbal numérica (EVN) y sedación con escala de agitación-sedación de Richmond (RASS) de los 0 a los 120 minutos postanestesia. Resultados: Las dosis de 1 a 3 μg/kg de buprenorfina no ocasionaron efectos adversos. El mantenimiento de analgesia es mayor con 2 μg/kg (p = 0.019) y 3 μg/kg (p = 0.045). Las dosis de 1 y 2 μg/kg presentan un nivel de sedación menor. Conclusiones: La analgesia multimodal disminuyó un 200% el dolor postquirúrgico inmediato. Las dosis de 2-3 μg/kg de buprenorfina son efectivas para el control del dolor con menor incidencia de efectos adversos y un nivel de sedación superficial durante el postoperatorio.

Abstract: Introduction: Posterior pain in thoracoscopy has an 80% incidence. These procedures are done under general anesthesia or sedoanalgesia. The buprenorphin in dosage of 4 μg/kg it's the foundation for post-operatory pain treatment, nevertheless, smaller dosage can be sufficient. The objective of this study is to demonstrate that a dosage of buprenorphin from 1-3 μg/kg provides suitable analgesia with less side effects during post-operatory in patients who underwent thoracoscopic surgery. Material and methods: We conducted a double-blind, prospective, transversal study, in 48 patients which underwent a thoracoscopy divided in 3 groups: A (1 μg/kg), B (2 μg/kg), and C (3 μg/kg) treated with buprenorphin. We studied side effects, pain intensity (NVE), and sedative effect (RASS) from 0 to 120 minutes postanesthesia. Results: Dosage from 1 to 3 μg/kg did not generate side effects. The analgesia effect is higher with 2 μg/kg (p = 0.019) and 3 μg/kg (p = 0.045). Dosage of 1 and 2 μg/kg have lower sedative effect. Conclusion: The multimodal analgesia was diminished by 200% inmidiate postsurgical pain. Dosage from 2-3 μg/kg of buprenorphine are effective for pain control with less side effects and a superficial sedative effect during post-operatory.

Analgesia multimodal una alternativa para el paciente quirúrgico / Multimodal analgesia: an alternative for the surgical patient

Introducción: El dolor posterior a una intervención quirúrgica, es un síntoma frecuentemente observado, no cumple una función útil y el peligro de no tratarlo aumenta la morbilidad y mortalidad posoperatoria. Objetivo: Destacar la importancia de la analgesia multimodal en el control del dolor agudo posoperatorio. Métodos: Revisión en la literatura impresa tanto nacional como internacional, sobre la analgesia y la modalidad multimodal y además, se hizo búsqueda en Internet. En los artículos revisados se obtuvieron distintos aspectos clínicos de la analgesia multimodal y de sus protocolos. Resultados: En la actualidad para mitigar el dolor y alcanzar la máxima expresión en la analgesia posoperatoria se han desarrollado diferentes modalidades analgésicas, aunque de todas ellas solo ha alcanzado mayor grado de recomendación, la analgesia multimodal porque es capaz de conseguir con su efecto sinérgico y con pequeñas dosis, una mejor potencia para producir analgesia y menos efectos adversos. Consideraciones finales: La analgesia multimodal logra un control adecuado del dolor agudo posoperatorio, disminuye las complicaciones posoperatorias y la necesidad de analgesia de rescate, pero todo esto depende del protocolo de analgesia multimodal propuesto, la vía de administración de los fármacos elegidos, sus dosis y el cumplimiento de los intervalos de aplicación(AU)

Introduction: The pain after surgery is a frequently observed symptom, it is not a useful function and the danger of not treating it increases postoperative morbidity and mortality. Objective: To highlight the importance of multimodal analgesia in the control of acute postoperative pain. Methods: It was made a review in the printed literature both national and international on the multimodal analgesia, and in addition, a search in Internet. In the reviewed articles there were obtained different clinical aspects of multimodal analgesia and its protocolization. Results: Nowadays, in order to mitigate the pain and achieve the maximum expression in the postoperative analgesia, there have been developed different analgesic modalities, although of all of them it only has achieved a greater degree of recommendation, the multimodal analgesia because it is capable of achieving with its synergetic effect and with small doses, a better power to produce analgesia and fewer adverse effects. Conclusions: The multimodal analgesia achieved adequate control of acute postoperative pain, decreasing the inherent complications of this state and the need of rescue analgesia. All of the above depends on the proposed protocol of multimodal analgesia, the route of administration of the chosen drugs, their doses and the compliance of the application intervals(AU)

[Is postoperative acute pain control in colorectal surgery better within an enhanced recovery after surgery program (ERAS)?] / ¿Mejora el control del dolor postoperatorio en cirugía colorrectal tras la implementación de un protocolo de rehabilitación intensificada (ERAS)?

BACKGROUND AND OBJECTIVE: A good acute pain control is necessary to achieve the main objective of Enhanced recovery After Surgery (ERAS) programs and accelerate recovery. The study objective is to evaluate postoperative (PO) acute pain, PO opioid consumption, and its association with functional recovery, after implementing a colorectal surgery ERAS program. An analysis was made as regards drugs adverse effects. METHODS: Observational cohort study on scheduled colorectal Surgery: one prospective cohort subjected to the ERAS care program, and one retrospective cohort that received traditional non-standardised care. A record was made of mean pain intensity (measured by a visual analogue scale, which classifies pain intensity from 0 to 10, from lower to higher intensity), as well as the amount of opioid consumption on the day of surgery and on the first three postoperative days, and drugs adverse effects. An analysis was made of the association between PO opioid consumption and ERAS program, and between PO opioid consumption and functional recovery. RESULTS: The study included a total of 410 patients (313 in the ERAS group and 97 in the control group). In the ERAS group, it was observed that the mean visual analogue scale was less than 2, with a smaller amount of PO opioid consumption, on each single day and the accumulated amount of the four days (4 [0-24] vs. 0 [0-4], P<.001). PO opioid consumption was associated with functional recovery (OR 0.97 [95% CI; 0.96-0.99], P=.011). No drugs adverse effects were observed. CONCLUSIONS: After implementing a colorectal Surgery ERAS program, good pain control was achieved, as well as a reduction in PO opioid consumption, which is associated with functional recovery. No drugs adverse effects were observed.

Strategies of analgesic treatment after cesarean delivery. Current state and new alternatives. / Estrategias de tratamiento analgésico tras cesárea. Estado actual y nuevas alternativas.

The number of caesarean sections performed worldwide is increasing, and with it, the need for the optimal analgesia strategies. Deficient postoperative analgesia increases the need for opioids, delays recovery, and is associated with chronic pain and postpartum depression. It is essential to find good postoperative pain control strategies that facilitate early mobility, early recovery, and early hospital discharge with minimal side effects on the mother and infant. Multimodal analgesia based on neuroaxial anaesthesia with morphine in combination with non-opioids such as non-steroidal anti-inflammatory drugs and paracetamol, gives the best post-caesarean analgesia outcome, and allows anaesthesiologists to reserve opioids, corticoids, gabapentin, magnesium or ketamine for situations where neuroaxial anaesthesia cannot be performed, for high-risk patients, or when pain is difficult to control. Peripheral nerve block techniques can also be added, such as transverse abdominis plane block, erector spinae block, or continuous wound infiltration.

Infusão de morfina e cetamina, associada ou não à lidocaína, em gatas submetidas à ovariossalpingo-histerectomia / Infusion of morphine and ketamine, with or without lidocaine, in cats undergoing ovariohysterectomy

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

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

Se busca evaluar el dolor durante el postoperatorio de acuerdo a la técnica utilizada: artroscópica o mini abierta bajo el protocolo de analgesia multimodal. Materiales y métodos Fueron incluidos 60 pacientes en el estudio, de los cuales se llevaron 24 pacientes a cirugía mini abierta y 36 pacientes a cirugía artroscópica entre mayo 2017 y junio 2018. Se realizo seguimiento hasta el primer mes postoperatorio. El desenlace primario es el dolor de acuerdo a la escala visual análoga (EVA) en los diferentes grupos de acuerdo a los diferentes momentos del postoperatorio. Resultados La mediana de dolor postoperatorio fue menor en los pacientes llevados a cirugía mini-abierta con una diferencia estadísticamente significativa en la primera (0 vs 4 (p = 0.001)), segunda hora de postoperatorio (0 vs 1 (p=0.016)) y en el control al mes postoperatorio (3 vs 5 (p=0.043)). Conclusión El dolor en el postoperatorio es menor para el grupo de cirugía mini abierta, con diferencia estadísticamente significativa en las dos primeras horas del postoperatorio y al mes de la cirugía. Estos resultados podrían atribuirse a la inflamación del hombro dada por la hidratación de los tejidos con la artroscopia y también por que las lesiones eran de mayor tamaño en el grupo de cirugía artroscópica. Nivel de Evidencia: II

Background Rotator cuff surgery improve symptoms and function in patients who have not responded to a conservative treatment. However, pain can be severe and uncomfortable after surgery requiring adequate analgesia. We aimed to evaluate pain during the postoperative period after rotator cuff surgery in two different groups: arthroscopic and mini open surgical repair both under a multimodal analgesia protocol. Methods Sixty patients were included in the study, 24 patients underwent mini-open surgery and 36 patients underwent arthroscopic surgery between May 2017 and June 2018. Final follow-up was done on postoperative day 30. The primary outcome is pain according to the visual analog scale (VAS) in the two different groups during different postoperative moments. Results Median postoperative pain was lower in patients undergoing mini-open surgery than in patients undergoing arthroscopic surgery on the first postoperative hour (0 vs 4 (p=0.001)), during the second postoperative hour (0 vs 1 (p=0.016)) and at final follow up (3 vs 5 (p=0.043)). Conclusion Pain during the postoperative period was lower for patients undergoing mini-open surgery, with a statistically significant difference during the first two postoperative hours and at final follow up. These results can be attributed to the local inflammation of the shoulder caused by the hydration of the tissues with arthroscopy surgery and bigger size tears in the group of arthroscopy surgery. Evidence Level: II.

Recuperação anestésica e analgesia residual da infusão continua intravenosa de fantanil, lidocaína, cetamina e fentanyl-lidocaína-cetamina associados à anesthesia total intravenosa com Propofol em cadelas submetidas à ovariossalpingo-histerectomia eletiva / Anesthetic recovery and residual analgesia of constant rate infusion intraoperative of fentanyl, lidocaine, ketamine or fentanyl-lidocaine-ketamine associated with total intravenous anesthesia with propofol in bitches submitted to elective ovariohysterectomy

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

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

Efectos cardiopulmonares y ácido-base de la infusión continua de fentanilo, ketamina y lidocaína en pacientes caninos ASA I / Cardiopulmonary and acid-base effects of continuous infusion of fentanyl, ketamine and lidocaine in canines ASA I / Efeitos cardio-pulmonares e ácido-base da infusão contínua de fentanil, cetamina e lidocaína em pacientes caninos ASA I

Resumen La combinación de fentanilo, lidocaína y ketamina (FLK) se ha utilizado am- pliamente en la cirugía canina como parte del protocolo analgésico. Algunos efectos asociados con su aplicación han sido descritos por la literatura. El objetivo del presente trabajo fue evaluar los efectos cardiopulmonares pro- ducidos por la infusión de FLK y el uso de isoflurano durante la cirugía en pacientes caninos ASA I. Las muestras fueron tomadas de nueve hembras caninas de diferentes razas, edades y tamaños que se presentaron para la ovariohisterectomía y recibieron una infusión continua de FLK (0,08, 30 y 15 µg/kg/min, respectivamente) como parte del protocolo analgésico. Antes (tiempo 1; T1) y durante (tiempo 2; T2) la cirugía se tomaron medidas de fre- cuencias cardíaca y respiratoria, presión arterial no invasiva, índice y gasto cardíaco, saturación arterial de oxígeno, dióxido de carbono espirado, tempe- ratura, presión parcial arterial de dióxido de carbono y oxígeno, bicarbonato, pH sanguíneo, dióxido de carbono total y lactato sanguíneo. Los resultados de la temperatura corporal y el pH en T1 y T2 fueron estadísticamente dife- rentes (p<0,05). Se concluye que no hubo diferencia entre los efectos de las variables cardiorrespiratorias y hemodinámicas en T1 y T2. Los resultados encontrados indican que los cambios en el pH y la temperatura se dieron por factores adicionales a la infusión FLK. Aunque las variables cardiovasculares y hemodinámicas no se encontraron como significativas, fue posible observar una mejora en la perfusión tisular y la estabilidad hemodinámica.

Abstract The combination of fentanyl, lidocaine, and ketamine (FLK) has been widely used in canine surgery as part of the analgesic protocol. Some effects associated with its application have been described by the literature. The objective was to evaluate the cardiopulmonary effects produced by the infusion of FLK and the use of isoflurane during surgery in canine ASA I patients. Samples was taken of nine healthy female dogs of different breeds, ages, and sizes undergoing ovariohysterectomy that received a continuous infusion of FLK (0,08, 30, and 15 µg/kg/min, respectively) as part of the analgesic protocol. The results of cardiac and respiratory rates, non-invasive blood pressure monitoring, cardiac output and index, arterial oxygen sa- turation, end-tidal carbon dioxide, body temperature, arterial partial pressure of carbon dioxide and oxygen, bicarbonate, blood pH, total carbon dioxide, and blood lactate were measured before (time 1; T1) and during (time 2; T2) the surgery. Body temperature and acid base status at T1 and T2 were statistically different (p<0,05). In contrast, there was no difference between the effects of the analgesic protocol on cardiorespiratory and hemodynamic variables at T1 and T2. The results found indicate that changes in pH and temperature were due to additional factors different conditions outside the FLK infusion. Al- though cardiovascular and hemodynamic variables were not found as significant, it was possible to observe an improving on tissue per- fusion and hemodynamic stability.

Resumo A combinação de fentanil, lidocaína e cetamina (FLK) tem sido amplamente utilizada em cirurgia canina como parte do protocolo analgésico. Alguns efeitos associados à sua aplicação foram descritos na literatura. O objetivo do presente trabalho foi avaliar os efeitos cardiopulmonares produzidos pela infusão de FLK e o uso de iso- flurano durante a cirurgia em pacientes caninos ASA I. As amostras foram coletadas de nove fêmeas caninas de diferentes raças, idades e tamanhos apresentados para ovario-histerectomia e recebeu infusão contínua de FLK (0,08, 30 e 15 µg/kg/min, respectivamente) como parte do protocolo analgésico. Antes (tempo 1; T1) e duran- te (tempo 2; T2) a cirurgia fazia medições das frequências cardíaca e respiratória, pressão arterial não invasiva, índice e débito cardíaco, saturação arterial de oxigênio, dióxido de carbono expirado, temperatura, pressão parcial de dióxido de carbono e oxigênio, bicarbonato, pH no sangue, dióxido de carbono total e lactato no sangue. Os resultados de temperatura corporal e pH em T1 e T2 foram estatisticamente diferentes (p <0,05). Conclui-se que não houve diferença entre os efeitos das variá- veis cardiorrespiratórias e hemodinâmicas em T1 e T2. Os resultados encontrados indicam que alterações no pH e temperatura foram devidas a fatores adicionais à infusão de FLK. Embora as variáveis cardiovasculares e hemodinâmicas não ten- ham sido significativas, foi possível observar uma melhora na perfusão tecidual e na estabilidade hemodinâmica.

Recomendaciones analgésicas en cirugía de reemplazo de cadera / Analgesic recommendations in hip replacement surgery

Resumen: La osteoartritis de cadera es la segunda causa de discapacidad funcional del aparato locomotor. Se presenta en adultos mayores de 35 años en 3 a 11%. Caracterizada por dolor al deambular, al subir o bajar escaleras, mejora con el reposo, pero evoluciona hasta limitada movilidad articular, crujido, rigidez e inestabilidad, restringiendo la funcionalidad y calidad de vida del individuo. La artroplastía total de cadera es la intervención indicada cuando la sintomatología es severa, persistente y han fallado otras terapéuticas. Tiene el objetivo de mejorar la calidad de vida, reducir el dolor y mejorar la función del paciente. Sin embargo, es un procedimiento que presenta dolor moderado a severo en el postoperatorio inmediato y una prevalencia de dolor crónico de 10 a 35%. La analgesia multimodal tiene que ser considerada para disminuir los efectos secundarios de los medicamentos y disminuir el uso de opioides (visita http://www.painoutmexico.com para obtener la versión completa del artículo y el diagrama de recomendaciones).

Abstract: Hip osteoarthritis is the second cause of functional impairment of the locomotor system. Its prevalence in adults over 35 years old in 3 to 11%. Characterized by a pain to walking, going up or down stairs, it improves with rest, that reaches a limited joint mobility, crunching, rigidity and instability restricting the functionality and quality of life. Total hip arthroplasty is the intervention indicated when the symtomatology is severe and persistent that have failed other therapeutics. It aims to improve the quality of life, reduce pain and improve the function of the patient. However, it is a procedure that is accompanied by moderate to severe pain in the immediate postoperative period and a chronic pain prevalence of 10 to 35%. Multimodal analgesia has to be considered to reduce the side effects of medications and reduce the use of opioids (visit http://www.painoutmexico.com to see the full article and recommendations diagram).

Analgesia en cirugía torácica (toracotomía) / Analgesia in thoracic surgery (thoracotomy)

Resumen: La cirugía torácica abierta se encuentra entre las cirugías más dolorosas y sus resultados se ven afectados adversamente por el malestar postoperatorio. La analgesia óptima en toracotomía, la disminución en el consumo de narcóticos, un despertar rápido y predecible, la prevención de efectos adversos, la movilización temprana y maniobras de fisioterapia respiratoria, así como el uso seguro de fármacos en recuperación y piso, son las estrategias más importantes para un manejo óptimo perioperatorio. Hasta hace unos años, la analgesia epidural era considerada el estándar analgésico; sin embargo, intervenciones como el bloqueo paravertebral también han sido evaluadas. El síndrome de dolor postoracotomía (PTPS) es una complicación bien reconocida, su incidencia varía entre el 15 y 67% de acuerdo con la definición. Se realizó la búsqueda en diversas fuentes de literatura para poder emitir recomendaciones perioperatorias, con mayor evidencia, esto se realizó con un equipo multidisciplinario para la emisión del manejo multimodal del dolor (visita http://www.painoutmexico.com para obtener la versión completa del artículo y el diagrama de recomendaciones).

Abstract: Open thoracic surgery is among the most painful surgeries and its results are adversely affected by postoperative discomfort. The optimal analgesia in thoracotomy, the decrease in the consumption of narcotics, a rapid and predictable awakening, the prevention of adverse effects, the early mobilization and maneuvers of respiratory physiotherapy, as well as the safe use of drugs, are the most important strategies for optimal perioperative management. Until a few years ago, epidural analgesia was considered the gold standard, however, interventions such as paravertebral block have been evaluated as well. Post-thoracotomy pain syndrome (PTPS) is a well-recognized complication, its incidence varies between 15 and 67% according to the definition. This review includes recommendations of literature sources to be able to translate perioperative recommendations with the highest evidence level, this was done including a multidisciplinary team for the issuance of multimodal pain management (visit http://www.painoutmexico.com to see the full article and recommendations diagram).

Recomendaciones en la analgesia para cirugía abdominal abierta / Recommendations in analgesia for open abdominal surgery

Resumen: La analgesia postoperatoria es uno de los componentes básicos en la recuperación funcional tras una intervención quirúrgica. El bloqueo de los estímulos nociceptivos contribuye a disminuir la respuesta al estrés quirúrgico, acelerando la rehabilitación y disminuyendo la incidencia de dolor crónico postoperatorio. Al bloquear las vías de conducción del dolor se limita la respuesta neuroendocrina, metabólica, inflamatoria e inmunitaria al estrés quirúrgico. La analgesia epidural sigue siendo el estándar de referencia en la cirugía abierta abdominal, en cuanto a la calidad de la analgesia dinámica y a la disminución de los tiempos de extubación, de ventilación mecánica y de las complicaciones respiratorias, con el potencial de reducir las tasas de eventos adversos relacionados (dolor no controlado, bloqueo motor y retención urinaria). La analgesia multimodal, basada en un concepto amplio de combinación de analgésicos, fármacos coadyuvantes y técnicas analgésicas, se presenta como una alternativa segura y eficaz (para ver el artículo completo visite http://www.painoutmexico.com).

Abstract: Postoperative analgesia is one of the basic components in functional recovery after surgical intervention. The blocking of nociceptive stimulus contributes to decrease the response to surgical stress, accelerating rehabilitation and decreasing the incidence of chronic postoperative pain. By blocking the pain conduction pathways, the neuroendocrine, metabolic, inflammatory and immune response to surgical stress is limited. Epidural analgesia continues to be the reference standard in open abdominal surgery, in terms of the quality of dynamic analgesia and the reduction of extubation times, mechanical ventilation and respiratory complications, with the potential to reduce the rates of related adverse events (uncontrolled pain, motor blockage and urinary retention). Multimodal analgesia, based on a broad concept of combination of analgesics, adjuvant drugs and analgesic techniques, is presented as a safe and effective alternative (full version visithttp://www.painoutmexico.com ) .

Manejo del dolor en nefrectomía abierta / Pain management in open nephrectomy

Resumen: La nefrectomía es el procedimiento quirúrgico en el cual se extirpa una parte o la totalidad de un riñón. Este procedimiento puede llevarse a cabo vía laparoscópica o abierta, esta última tiene tres vías de abordaje: por una incisión en flanco, toracoabdominal o transabdominal. Todas son amplias y el dolor postquirúrgico que se presenta va de una intensidad moderada a severa y en algunos pacientes puede convertirse en crónico. Para el manejo del dolor, en esta cirugía, se recomienda el uso de la analgesia multimodal, la cual consiste en usar fármacos con diferentes sitios de acción, así como el empleo de técnicas regionales con el uso de anestésicos locales. (visita http://www.painoutmexico.com para obtener la versión completa del artículo y el diagrama de recomendaciones).

Abstract: Nephrectomy is the surgical procedure in which part or all of a kidney is removed, this procedure can be carried out laparoscopically or openly. Open way has 3 boarding techniques: by an incision on the flank, thoraco-abdominal or trans-abdominal. All are wide and the postoperative pain that occurs ranges from a moderate to severe intensity and in some patients can become chronic. For the management of pain, in this surgery, the use of multimodal analgesia is recommended, which consists of using drugs with different sites of action as well as the use of regional techniques with the use of local anesthetics.
