Introducción: El dolor posoperatorio es un fenómeno observado con elevada frecuencia y constituye uno de los retos más importantes en el ámbito quirúrgico. Objetivo: Describir los resultados clínicos y hemodinámicos obtenidos con la utilización de anestesia peridural torácica alta como técnica analgésica durante el período posoperatorio en los pacientes intervenidos de tórax. Método: Se realizó un estudio descriptivo, longitudinal, prospectivo en el Hospital Abel Santamaría Cuadrado, entre enero de 2014 y enero de 2017. La muestra estuvo conformada por 37 pacientes que cumplieron con los criterios de inclusión y exclusión. Resultados: Predominaron los valores normales en los que no presentaron dolor posoperatorio, con 33 ± 5,23 y 33 ± 7,86 respectivamente. Se calculó una media de saturación de oxígeno de 99,48 por ciento y frecuencia respiratoria de 16 res/min. Se evidenció que 31 pacientes (83,78 por ciento) no presentaron complicaciones posoperatorias secundarias a la técnica analgésica. En la mayoría no fue necesaria la analgesia de rescate, elemento que representó el 89,19 por ciento. Resultó significativo que 32 pacientes (86,49 por ciento), manifestaron encontrarse satisfechos con el proceder y los resultados alcanzados. Conclusiones: La aplicación de la peridural con morfina para cirugía de tórax arrojó resultados muy efectivos como método analgésico con adecuada estabilidad, mínimas complicaciones requerimientos de rescate analgésico, lo que propició satisfacción por los pacientes(AU)

Introduction: Postoperative pain is a phenomenon that appears frequently and constitutes one of the most important challenges in the surgical field. Objective: To describe the clinical and hemodynamic results obtained with the use of high thoracic epidural as analgesic technique during the postoperative period in patients undergoing thoracic surgery. Method: A descriptive, longitudinal, prospective study was carried out in Abel Santamaría Cuadrado Hospital, during the period between January 2014 and January 2017. The sample consisted of 37 patients who met the inclusion and exclusion criteria. Results: In blood pressure and heart rate according to analgesic response, normal values prevailed in those without postoperative pain, with 33 ± 5.23 and 33 ± 7.86 respectively. A mean of oxygen saturation of 99.48 percent and respiratory rate of 16 res/min were calculated. It was evidenced that 31 patients (83.78 percent) did not present postoperative complications after the analgesic technique. In the majority, rescue analgesia was not necessary, an element that represented 89.19 percent. It was significant that 32 patients (86.49 percent) said they were satisfied with the procedure and the results achieved. Conclusions: The application of peridural with morphine for thoracic surgery yielded very effective results as an analgesic method with adequate stability, minimal complications and analgesic rescue requirements, which led to patient satisfaction(AU)

Eficacia analgésica y complicaciones a corto plazo de catéteres peridurales lumbares y torácicos en pacientes pediátricos: una evaluación retrospectiva / Analgesic efficacy and short-term complications of lumbar peridural catheters and thoracic in pediatric patients: a retrospective evaluation

Introducción: la analgesia peridural postoperatoria en niños es efectiva con catéteres insertados al nivel del sitio quirúrgico. Objetivo:comparar la eficacia y las complicaciones de catéteres insertados a nivel lumbar y torácico para analgesia postoperatoria. Método:revisamos la base de datos del Servicio de dolor agudo. Extrajimos información de pacientes de 0-18 años, con analgesia peridural postoperatoria. Los pacientes fueron divididos en grupo lumbar y torácico y, en cada grupo, por edades. Recopilamos información de: variables demográficas, tipo de cirugía, nivel de inserción del catéter peridural, solución de anestésico local administrada, analgésicos sistémicos, coadyuvantes peridurales, dolor postoperatorio y complicaciones. Dividimos las complicaciones según gravedad. Resultados: se analizaron 221 pacientes, 123 con catéter lumbar y 98 con catéter torácico. Catéteres peridurales lumbares y torácicos fueron principalmente insertados en niños de 1-3 años y mayores de 4 años respectivamente. Se utilizó bupivacaína 0,1-0,125 por ciento. Las cirugías fueron urológicas, intraabdominales, ortopédicas, torácicas y cardiovasculares. Los niños con catéteres torácicos tuvieron más dolor (mediana (rango): 3 (0-6) vs. 2 (0-4)) y necesitaron sus catéteres por más días (promedio (DE): 2,96 (1,06) vs. 2,53 (1,09) que aquellos con catéter lumbar. Los requerimientos analgésicos fueron similares en ambos grupos. Hubo 60 complicaciones (27,1 por ciento), principalmente menores (92 por ciento), sin diferencias entre los grupos lumbar y torácica (30 por ciento vs 23 por ciento) ni entre las diferentes edades. Conclusión: los catéteres peridurales insertados en relación al sitio quirúrgico, a nivel lumbar o torácico, proporcionarían analgesia postoperatoria clínicamente aceptable y comparable, con similar incidencia de complicaciones.(AU)

Introduction: postoperative epidural analgesia in children is effective with catheters inserted at the level of the surgical site. Objective: compare the efficacy and complications of epidural catheters inserted at the lumbar and thoracic level for postoperative analgesia in this population. Methods: we review the Acute Pain Service Database. We extracted information of patient from 0 to 18 years with postoperative epidural analgesia. Patients were divided into lumbar and thoracic groups and, in each group, by age. Collected data included: demographic, type of surgery, details of epidural catheters insertion, the local anesthetic administered, systemic analgesics and epidural adjuvant used, postoperative pain and complications. We divide complications according severity. Results: 221 patients were analyzed, 123 with lumbar and 98 with thoracic epidurals catheters. Lumbar and thoracic epidural catheters were mainly placed in patients 1-3 years and older than four years respectively. Bupivacaine 0.1-0.125 percent was the analgesic solution used. Performed surgeries were urological, intraabdominal, orthopedic, thoracic and cardiovascular. Children with thoracic catheters had more pain (median (IQR): 3 (0-6) vs. 2 (0-4)) and needed their catheters more days (mean (SD): 2.96 (1.06) vs. 2.53 (1.09)) than children with lumbar catheters.Analgesic requirements were similar between both groups. There were 60 complications (27.1 percent), mainly minors (92 percent), with no differences between lumbar and thoracic groups (30 percent vs. 23 percent respectively), and among age categories. Conclusion: the epidural catheters inserted about the surgical site, at the lumbar or the thoracic level would provide clinically acceptable and comparable postoperative analgesia with a similar rate of complications.(AU)

Analgesia pós-operatória da artroplastia do quadril: comparação do bloqueio de plexo lombar contínuo com a analgesia peridural / Postoperative analgesia for hip arthroplasty: comparison of continuous lumbar plexus block and epidural analgesia

RESUMO JUSTIFICATICA E OBJETIVOS: A dor pós-operatória da artroplastia total do quadril tem intensidade moderada a intensa, exigindo a realização de técnicas analgésicas eficazes. O objetivo deste estudo foi comparar o bloqueio do plexo lombar contínuo com a analgesia peridural em pacientes submetidos à artroplastia de quadril. MÉTODOS: Estudo retrospectivo, observacional e analítico dos pacientes submetidos à artroplastia de quadril durante dois anos, sob analgesia pós-operatória por bloqueios do plexo lombar contínuo e peridural. Os pacientes foram divididos de acordo com a técnica analgésica escolhida pelo anestesiologista. O protocolo consiste em infusão contínua de ropivacaína a 0,2% (5mL/h) via cateter de bloqueio do plexo lombar contínuo ou em ropivacaína a 0,1% e fentanil 3µg/mL (5mL/h) via cateter peridural. Recorrendo aos registos da Unidade de Dor Aguda, foram comparados os três dias pós-operatórios dos grupos bloqueio do plexo lombar contínuo e peridural em relação à intensidade da dor, analgesia de resgate, complicações e tempo de internação hospitalar. RESULTADOS: Foram incluídos 162 pacientes. A maioria de ambos os grupos não apresentou queixas de dor no primeiro dia pós-operatório (77,6% bloqueio do plexo lombar contínuo versus 79,2% peridural). Ambos os grupos não diferiram em relação à intensidade de dor nem à incidência de necessidade de analgesia de resgate (23,5% bloqueio do plexo lombar contínuo versus 22,1% peridural). O grupo bloqueio do plexo lombar contínuo registrou menos complicações (4,7% versus 23,4%), nomeadamente bloqueio motor, náuseas, vômitos e prurido. A rara ocorrência de complicações não permite detectar diferenças significativas entre as técnicas. A maioria dos pacientes de ambos os grupos obteve alta hospitalar no 3º dia pós-operatório. CONCLUSÃO: Em relação à analgesia peridural, o bloqueio do plexo lombar contínuo proporcionou analgesia semelhante com menos complicações.

ABSTRACT BACKGROUND AND OBJECTIVES: Postoperative pain after total hip arthroplasty is moderate to severe and requires effective analgesic techniques. This study aimed at comparing continuous lumbar plexus block and epidural analgesia in patients submitted to hip arthroplasty. METHODS: This is a prospective, observational and analytical study of patients submitted to hip arthroplasty in a two-year period, under postoperative analgesia with continuous lumbar plexus block and epidural analgesia. Patients were divided according to the analgesic technique chosen by the anesthesiologist. The protocol consists in continuous perfusion of 0.2% ropivacaine (5mL/h) via continuous lumbar plexus block catheter or 0.1% ropivacaine and fentanil (3μg/mL) (5mL/h) via epidural catheter. Using Acute Pain Unit records, three postoperative days were compared between continuous lumbar plexus block and epidural analgesia with regard to pain intensity, rescue analgesia, complications and hospital stay. RESULTS: Participated in the study 162 patients. Most patients of both groups had no pain in the first postoperative day (77.6% continuous lumbar plexus block versus 79.2% epidural). Both groups were not different with regard to pain intensity and need for rescue analgesia (23.5% continuous lumbar plexus block versus 22.1% epidural). Continuous lumbar plexus block group had fewer complications (4.7% versus 23.4%), namely motor block, nausea, vomiting and itching. The low number of complications does not allow the detection of significant differences between techniques. Most patients of both groups were discharged in the third postoperative day. CONCLUSION: As compared to epidural analgesia, continuous lumbar plexus block has provided similar analgesia with fewer complications.

Combined spinal-epidural anesthesia and non-pharmacological methods of pain relief during normal childbirth and maternal satisfaction: a randomized clinical trial / Anestesia combinada e métodos não farmacológicos para alívio da dor durante o trabalho de parto e satisfação materna: ensaio clínico randomizado

OBJECTIVE: The objective of this study was to compare maternal satisfaction with childbirth according to whether or not combined spinal-epidural anesthesia (CSE) of pain relief was used during labor. METHODS: A randomized, open clinical trial was performed with 70 pregnant women, 35 of whom received CSE anesthesia while 35 received only non-pharmacological forms of pain relief during labor. The variables evaluated were visual analogue scale (VAS) pain score, maternal satisfaction with the technique of pain relief used during childbirth and with delivery, the patient's intention to request the same technique in a subsequent delivery, and loss of control during delivery. RESULTS: VAS pain score decreased significantly in patients receiving CSE during vaginal delivery. Furthermore, maternal satisfaction with the technique of pain relief and with delivery was higher in the CSE group, and around 97 percent of the patients would repeat the same technique at future deliveries compared to 82.4 percent of the women in the group using only non-pharmacological methods. With respect to the women's impressions of their control during delivery, approximately half the women in both groups felt that they had lost control at some point during the process. CONCLUSION: The use of CSE was associated with a significant reduction in VAS pain scores during delivery and with greater maternal satisfaction with the pain relief method and with the childbirth process.

OBJETIVOS: Comparar a satisfação materna com o processo do nascimento de acordo com a realização ou não de métodos farmacológicos para alívio da dor do trabalho de parto. MÉTODOS: Realizou-se um ensaio clínico randomizado com 70 parturientes, 35 das quais receberam anestesia combinada (raquidiana e peridural associadas) e 35 receberam métodos não farmacológicos para alívio da dor durante o parto vaginal. As variáveis estudadas foram: escores de dor pela Escala Visual Analógica (EVA), satisfação materna com a técnica analgésica e com o parto, desejo de repetir a técnica analgésica em parto posterior e perda do controle sobre o parto. A análise estatística foi realizada no programa Epi-Info 3.5.3, com base na intenção de tratar. RESULTADOS: Pacientes recebendo anestesia combinada (AC) durante o parto vaginal experimentaram uma diminuição significativa dos escores da EVA e maior satisfação materna com a técnica analgésica e com o parto. A maioria das parturientes, cerca de 97 por cento do grupo da anestesia combinada, repetiu a técnica em partos futuros, contra 82,4 por cento do grupo dos métodos não farmacológicos. No que diz respeito ao sentimento de controle do parto, aproximadamente metade das parturientes dos dois grupos sentiu que em algum momento do parto perdeu o controle deste, não havendo diferença significativa entre os grupos. CONCLUSÃO: O uso da AC está associado a uma significante diminuição dos escores da dor durante o parto, e maior satisfação materna com a técnica analgésica e com o parto.
