ABSTRACT
OBJECTIVE@#To characterize the paraspinal muscles of adolescent idiopathic scoliosis (AIS) patients, and to further explore its etiology.@*METHODS@#Clinical records and paraspinal muscle biopsies at the apex vertebra region during posterior scoliosis correction surgery of 18 AIS were collected from November 2018 to August 2019. Following standardized processing of fresh muscle tissue biopsy, serial sections with conventional hematoxylin-eosin (HE) and histochemical and immunohistochemical (IHC) with antibody Dystrophin-1 (R-domain), Dystrophin-2 (C-terminal), Dystrophin-3 (N-terminal), Dystrophin-total, Myosin (fast), major histocompatibility complex 1 (MHC-1), CD4, CD8, CD20, and CD68 staining were obtained. Biopsy samples were grouped according to the subjects' median Cobb angle (Cobb angle ≥ 55° as severe AIS group and Cobb angle < 55° as mild AIS group) and Nash-Moe's classification respectively, and the corresponding pathological changes were compared between the groups statistically.@*RESULTS@#Among the 18 AIS patients, 8 were in the severe AIS group (Cobb angle ≥55°) and 10 in the mild AIS group (Cobb angle < 55°). Both severe and mild AIS groups presented various of atrophy and degeneration of paraspinal muscles, varying degrees and staining patterns of immune-expression of Dystrophin-3 loss, especially Dystrophin-2 loss in severe AIS group with significant differences, as well as among the Nash-Moe classification subgroups. Besides, infiltration of CD4+ and CD8+ cells in the paraspinal muscles and tendons was observed in all the patients while CD20+ cells were null. The expression of MHC-1 on myolemma was present in some muscle fibers.@*CONCLUSION@#The histologic of paraspinal muscle biopsy in AIS had similar characteristic changes, the expression of Dystrophin protein was significantly reduced and correlated with the severity of scoliosis, suggesting that Dystrophin protein dysfunctions might contribute to the development of scoliosis. Meanwhile, the inflammatory changes of AIS were mainly manifested by T cell infiltration, and there seemed to be a certain correlation between inflammatory cell infiltration, MHC-1 expression and abnormal expression of Dystrophin. Further research along the lines of this result may open up new ideas for the diagnosis of scoliosis and the treatment of paraspinal myopathy.

OBJECTIVE@#To observe the effect of acupotomy on the fat infiltration degree of lumbar multifidus muscle (LMM) in patients with lumbar disc herniation after percutaneous transforaminal endoscopic discectomy (PTED).@*METHODS@#A total of 104 patients with lumbar disc herniation treated with PTED were randomly divided into an observation group (52 cases, 3 cases dropped off) and a control group (52 cases, 4 cases dropped off). Patients of both groups received rehabilitation training of two weeks 48 h after PTED treatment. The observation group was treated with acupotomy (L3-L5 Jiaji [EX-B 2]) once within 24 h after PTED. In the two groups, the fat infiltration cross sectional area (CSA) of LMM was compared before and 6 months after PTED, the visual analogue scale (VAS) score and Oswestry disability index (ODI) score were observed before and 1, 6 months after PTED. The correlation between fat infiltration CSA of LMM in each segment and VAS score was analyzed.@*RESULTS@#Six months after PTED, the fat infiltration CSA of LMM in L4/L5 and the total L3-S1 segments of the observation group was lower than that before PTED (P<0.05), and the fat infiltration CSA of LMM in L4/L5 of the observation group was lower than the control group (P<0.01). One month after PTED, the ODI and VAS scores of the two groups were lower than those before PTED (P<0.01), and those in the observation group were lower than the control group (P<0.05). Six months after PTED, the ODI and VAS scores of the two groups were lower than those before PTED and 1 month after PTED (P<0.01), and those in the observation group were lower than the control group (P<0.01). There was a positive correlation between the fat infiltration CSA of LMM in the total L3-S1 segments and VAS scores in the two groups before PTED (r = 0.64, P<0.01). Six months after PTED, there was no correlation between the fat infiltration CSA of LMM in each segment and VAS scores in the two groups (P>0.05).@*CONCLUSION@#Acupotomy can improve the fat infiltration degree of LMM, pain symptoms and activities of daily living in patients with lumbar disc herniation after PTED.

Introducción: La sarcopenia está revistiendo importancia en el estudio de diferentes enfermedades para predecir la morbimortalidad en el perioperatorio. Los objetivos de este estudio fueron evaluar la eficacia de la tomografía y la resonancia en la medición de la musculatura del psoas y los paraespinales, y comparar estos índices con la edad, el sexo y la enfermedad. materiales y métodos: Se utilizaron las tomografías computarizadas y las resonancias magnéticas de pacientes ambulatorios. La medición de los músculos se realizó en los pedículos de L3 y L4. Resultados: El estudio incluyó 18 tomografías y 34 resonancias. El rango de edad de los pacientes era de 15 a 80 años, divididos en grupos etarios. En los promedios globales, en ambos estudios, el sexo masculino estaba por encima del promedio global. Con respecto a los rangos etarios, se observó que el primer grupo (15-29 años) tenía un mayor volumen muscular y de unidades Hounsfield en el psoas comparado con el grupo >60 años. Los pacientes que consultaron por espondilolistesis tenían menos masa muscular que aquellos con discopatías. Conclusiones: No existe diferencia entre la resonancia magnética y la tomografía computarizada en cuanto a la medición de los músculos paraespinales y psoas. Queda en evidencia que la disminución del volumen muscular es común en pacientes de mayor edad y con enfermedades que afectan el balance espinal. Nivel de Evidencia: IV
background: Sarcopenia is becoming increasingly significant in the research of various diseases to predict morbidity and mortal-ity in the perioperative period. Objectives: The objectives of this study were to evaluate the efficacy of computed tomography and magnetic resonance imaging in measuring the psoas and paraspinal muscles and to compare these indexes with age, sex, and pathology. materials and methods: Computed tomography and magnetic resonance imaging of outpatients were used. Muscle measurements were taken at the L3 and L4 pedicles. Results: The study included 18 CT and 34 MRI scans. The patients were divided into groups based on their age range, which was 15 to 80 years. In the overall averages, males were above the global average in both studies. Regarding age ranges, it was observed that the first group (15-29 years) had a higher muscle volume and Hounsfield units in the psoas compared to the >60 age group. Patients consulting for spondylolisthesis had less muscle mass than those with discopathy. Conclusions: There is no difference between magnetic resonance imaging and computed tomography in measuring the paraspinal and psoas muscles. It is evident that the decrease in muscle volume is common in older patients and those with diseases that affect spinal balance. Level of Evidence: IV

OBJECTIVE@#To observe the effect of electroacupuncture on motor function and muscle state in patients with primary osteoporosis (POP).@*METHODS@#A total of 60 female patients with POP were randomized into an observation group (30 cases, 1 case dropped off) and a control group (30 cases, 1 case dropped off). On the basis of adjusting lifestyle, caltrate was given orally in the control group, 2 pills a day for 4 weeks. On the basis of the treatment in the control group, electroacupuncture was applied at Zusanli (ST 36), Yanglingquan (GB 34), Ganshu (BL 18), Pishu (BL 20), Shenshu (BL 23), etc. in the observation group, with disperse-dense wave of 2 Hz/10 Hz in frequency, once every other day, 3 times a week for 4 weeks. The time of timed up-and-go test (TUGT) and the value of 10 m maximal walking speed (10 m MWS) before and after treatment were compared in the two groups, and the Young's modulus values of bilateral multifidus muscles in prone position and sitting position before and after treatment were compared by real-time shear wave elastography (SWE) in the two groups.@*RESULTS@#After treatment, the TUGT time was decreased compared before treatment in the observation group (P<0.01), and that in the observation group was shorter than the control group (P<0.01). After treatment, the value of 10 m MWS test was increased compared before treatment in the observation group (P<0.05). After treatment, the Young's modulus values of bilateral multifidus muscles in prone position and sitting position were increased compared before treatment in the observation group (P<0.01); except for the left side in sitting position, the Young's modulus values of multifidus muscles in the observation group were higher than those in the control group (P<0.01, P<0.05).@*CONCLUSION@#On the basis of oral caltrate, electroacupuncture can improve the motor function and muscle state in patients with POP.

ABSTRACT Introduction: The paravertebral musculature is essential for the biomechanics and stability of the spine, and its involvement in the pathophysiology of spinal diseases has been demonstrated. Qualitative evaluation of muscle degeneration is usually performed by analyzing the fat infiltration rate proposed by the Goutallier classification system. Objective: The objective of this study is to analyze the intra- and interobserver agreement of the Goutallier Classification for the evaluation of fatty degeneration of the multifidus muscle, using magnetic resonance imaging exams. Methods: The study included 68 patients, all diagnosed with symptomatic disc hernia and indicated for surgery. Preoperative magnetic resonance images were used for the analyses. The images were initially evaluated by two orthopedists and two medical students, and then re-evaluated after two weeks. Intra- and inter-observer reliability analysis was performed using the Fleiss Kappa test and the Landis and Koch criteria. All the analyses were performed using the R statistical environment (R Development Core Team, version 3.3.1, 2016) and the significance level was set at 5%. Results: The percentages of intra- and inter-observer agreement were 86.76% and 61.03%, respectively. The intraobserver agreement was near perfect and the interobserver agreement was moderate. Conclusion: The Goutallier Classification System showed moderate interobserver and intraobserver agreement, being a relevant tool for the evaluation of paravertebral musculature fat replacement. Level of evidence II; Prospective study for diagnostic purposes.

The Erector Spinae Plane (ESP) block, described in 2016 by Dr. Forero et al, was used to treat neuropathic pain and postoperative acute pain. It was described as an interfascial block in the erector spinae plane, where it manages to block both ventral and dorsal branches of the spinal nerve. Due to scarce literature on its applicability in urological endoscopic surgeries, we formulate the hypothesis that it would be an effective opioid-sparing analgesic alternative in patients undergoing TULIP. Therefore, bilateral ESP was performed in a 69-year-old patient, who underwent transurethral prostatectomy guided by laser induced (TULIP) for benign prostatic hyperplasia. The patient did not require rescue medication, reported a maximum VAS of 4/10. At 72 hours postoperatively, the patient kept a VAS of 0/10, without nausea and vomiting, with a Likert satisfaction level of 1
El bloqueo del plano erector de la espina (ESP) fue descrito en 2016 por el Dr. Forero et al., con el afán de tratar el dolor neuropático y el dolor agudo posoperatorio. Consiste en un bloqueo interfascial en el plano del erector de la espina, en el cual se logra el bloqueo tanto de ramas ventrales como dorsales de los nervios espinales. Debido a la falta de literatura sobre su indicación en cirugías endoscópicas urológicas se formula la hipótesis de que podría considerarse como una alternativa analgésica efectiva ahorradora de opioides en pacientes sometidos a RTU-P. Por lo anterior se realizó el bloqueo ESP de manera bilateral a un paciente de 69 años, el cual fue sometido a prostatectomía transuretral guiado por láser inducido (TULIP) por hiperplasia prostática benigna. El paciente no requirió opioides de rescate, con EVA 0/10 en posoperatorio, valor que se mantuvo de la misma manera por 72 h, tanto en reposo como en movimiento, sin la presencia de náuseas o vómitos y una escala de satisfacción de Likert de 1.

Erector spinae plane block (ESP) is a regional anesthesia technique consisting of blocking the interfascial plane, where local anesthetic (LA) is injected at the site where the dorsal branch of the spinal nerve emerges. There are various publications on the application of the block (EPS) in the adult population, however there are few reports of the use of this block in pediatric surgery. We present the first case report of an infant under 9 months of age with the presence of a tumor in the anterior mediastinum, who underwent a resection through the 6th intercostal space, previous blockage of the erector spinae under ultrasound vision. The patient did not present adverse effects and was discharged on the fourth postoperative day.

Abstract The erector spinae plane block is a safe and effective regional anesthesia technique, which has earned new indications perioperatively since its description. We introduce two pediatric anesthesia cases in which we performed the erector spinae plane block during intermediate/major orthopedic surgeries. The first patient is a 2 year-old girl submitted to surgical treatment of developmental dysplasia of the hip. The second patient is a 14 year-old boy submitted to surgical treatment of bilateral clubfoot. This last patient is potentially the first published case in which the erector spinae plane block was performed for ankle and foot surgery. Both cases experienced excellent analgesia, avoiding opiate requirement completely.

Apresentamos dois casos de bloqueio do plano eretor da espinha realizados para analgesia de cirurgia ortopédica pediátrica de médio/grande porte. O primeiro: menina de 2 anos submetida a tratamento cirúrgico de displasia do desenvolvimento do quadril. O segundo: menino de 14 anos submetido a correção de pé valgo bilateral. Este último, no melhor do nosso conhecimento, é o primeiro caso de bloqueio do plano eretor da espinha em cirurgia de tornozelo/pé descrito na literatura. Os casos tiveram analgesia pós-operatória adequada, sem necessidade de opioides.

Abstract Background: Failure of ductus arteriosus closure in preterm neonates results in a left-to-right shunt that leads to variable severities of hemodynamic and respiratory distress. When medical therapy fails, surgical ligation via left lateral thoracotomy remains an alternative approach and can be performed in the operating room or at the bedside with a low mortality rate. Opioid-based anesthesia is a frequent choice among anesthesiologists who manage patent ductus arteriosus cases based on the suppression of the stress response and maintenance of hemodynamic stability. This rationale suggests that regional anesthesia may also be an advantageous technique and may benefit earlier weaning from ventilation. Blocking afferent signals before incision may also modulate the long-term consequences of altered sensory perception and pain responses. Case report: We present two cases of general anesthesia combined with erector spinae plane block as part of multimodal anesthesia in premature twins undergoing patent ductus arteriosus closure. Discussion: In these cases, the use of erector spine plane block combined with general anesthesia was efficient to minimize the negative impact of surgery and allowed a reduction in the amount of intraoperative opioid use for patent ductus arteriosus closure.
Resumo Justificativa: A persistência do canal arterial em neonatos prematuros resulta em shunt esquerdo-direito com alterações hemodinâmicas e desconforto respiratório de gravidade variável. Quando o tratamento clínico não é bem sucedido, o fechamento cirúrgico via toracotomia lateral esquerda continua sendo a abordagem alternativa, e pode ser realizado no centro cirúrgico ou à beira leito com baixa taxa de mortalidade. A anestesia baseada em opioides é frequentemente escolhida pelos anestesiologistas nos casos de fechamento de canal arterial devido à supressão de resposta ao estresse e manutenção da estabilidade hemodinâmica. Essa justificativa sugere que a anestesia regional também pode ser uma técnica vantajosa e que promove desmame mais precoce do ventilador. O bloqueio dos estímulos aferentes antes da incisão também pode modular os efeitos no longo-prazo, tanto da percepção sensorial quanto das respostas à dor. Relato de caso: Apresentamos dois casos de anestesia geral associada a bloqueio do plano do músculo eretor da espinha como parte de anestesia multimodal em gêmeos prematuros submetidos a fechamento de canal arterial persistente. Discussão: Nos dois casos descritos, o bloqueio do plano do músculo eretor da espinha associado à anestesia geral foi eficiente para minimizar o impacto negativo da cirurgia, e possibilitou a redução na quantidade de opioide usado durante cirurgia para fechamento de persistência canal arterial.

Extraabdominal desmoid tumors are uncommon soft-tissue tumors. The etiology of the tumor is still unclear. Injury is one of the etiological factors of soft-tissue tumors. A 41-year-old female patient who had a traumatic vertebral body fracture on the thoracic spine was treated conservatively. Two and a half years later, she presented a painful, palpable swelling on the thoracolumbar region. In the present report, was discuss the patient, who underwent a surgery to remove the desmoid tumor (aggressive fibromatosis), within the context of the current literature. The literature on desmoid tumor caused by a trauma is rare. This is the first case that demonstrates an extraabdominal desmoid tumor following a spinal fracture. The swelling on the region of the trauma must be examined carefully and desmoid tumor must be kept in mind as a possible diagnosis.

OBJECTIVE@#To compare the degeneration of lumbosacral multifidus muscle in patients with lumbar disc herniation.@*METHODS@#Thirty-five healthy volunteers and 35 patients with unilateral L lumbar disc herniation from December 2015 to September 2017 were recruited. There were 20 males and 15 females in each group, aged from 25 to 55 years old. In healthy volunteers group, the mean age was (35.66±8.73) years old and the BMI was (21.85±1.94) kg /m. In patients with lumbar disc herniation, the mean age was (36.09±7.70) years old, the BMI was (21.50±1.78) kg /m, the VAS score was 4.40±0.88, the course of disease was (11.20±7.14) months. Surface electromyography analysis was performed on the multifidus muscle of the two groups. The average myoelectric amplitude of the multifidus muscle in the two groups were compared.@*RESULTS@#The average myoelectric amplitude of the multifidus muscle of healthy volunteers was (48.84±7.77) µV on the left and (49.13±7.86) µV on the right. There was no significant difference between the two sides (>0.05). The average myoelectric amplitude of multifidus muscle in patients with lumbar disc herniation was(48.82±8.14) µV on the healthy side and (42.81±7.00) µV on the affected side, and the difference was statistically significant between two sides(0.05). There was significant difference in the average myoelectric amplitude of multifidus muscle between the affected side of lumbar disc herniation and on the left of healthy volunteers, and also between the affected side of lumbar disc herniation and on the right of healthy volunteers(<0.05).@*CONCLUSION@#Patients with chronic lumbar disc herniation have an imbalance in myoelectric activity, and the muscle strength of the multifidus muscle on the affected side is significantly reduced.

Abstract Objective and background: Erector spinae plane block is a novel analgesic truncal block that has been popularized due to its ease of performance and perceived safety. Erector spinae plane block has been postulated to target the ventral rami and rami communicates of spinal nerves, thus providing somatic and visceral analgesia. In this case series, we describe our experience of bilateral erector spinae plane block placed at the low thoracic level in open gynecologic oncology surgery in three patients. Method: Under ultrasound guidance, erector spinae plane blocks were done, preoperatively, at the 8th thoracic transverse process bilaterally. Numeric rating scale for pain and opioid consumption of the first 48 postoperative hours were recorded. Results: Pain scores ranged from 0 to 4 among the three patients and 48 h opioid consumption in oral morphine equivalents of 4, 6 and 18 mg. No adverse events were recorded up to patient discharge from the hospital. Conclusions: Erector spinae plane block provided effective analgesia in our case series. While its true mechanism of action remains obscure, the available case reports show encouraging analgesic results with no adverse events recorded. Formal prospective randomized trials are underway to provide further evidence on its efficacy, failure rate and safety.
Resumo Justificativa e objetivo: O bloqueio do plano do músculo eretor da espinha é um novo bloqueio troncular analgésico popularizado devido à sua facilidade de aplicação e segurança percebida. O bloqueio do plano do músculo eretor da espinha foi postulado para atingir os ramos ventrais e os ramos comunicantes dos nervos espinhais, proporcionando analgesia somática e visceral. Nesta casuística, descrevemos nossa experiência com o bloqueio do plano do músculo eretor da espinha bilateral depositado no nível torácico inferior em cirurgia oncológica ginecológica aberta em três pacientes. Método: Os bloqueios do plano do músculo eretor da espinha guiados por ultrassom foram administrados no pré-operatório, entre o 8° e o 10° processo transverso do tórax bilateralmente. Os valores de uma escala de classificação numérica para dor e consumo de opioides nas primeiras 48 horas de pós-operatório foram registrados. Resultados: Os escores de dor variaram de 0-4 entre as três pacientes e o consumo de opioide em 48 horas equivaleu à morfina oral (4, 6 e 18 mg). Nenhum evento adverso foi registrado até a alta hospitalar das pacientes. Conclusões: O bloqueio do plano do músculo eretor da espinha proporcionou analgesia efetiva em nossa casuística. Embora o mecanismo de ação verdadeiro permaneça obscuro, os relatos de casos disponíveis mostram resultados analgésicos encorajadores, sem eventos adversos registrados. Ensaios prospectivos randômicos formais estão em andamento para fornecer mais evidências sobre sua eficácia, taxa de falha e segurança.

Abstract Introduction: The erector spinae plane (ESP) block is a relatively new interfascial block about which several applications have been described, both in abdominal and thoracic surgical procedures. Case presentation: A 17-year old patient programed for removal of a Nuss bar through mini-thoracotomy. Following the induction with anesthesia, a US-guided bilateral ESP block was administered; no pain was reported during the immediate postoperative period and over the 48-hour follow-up. Conclusion: Bilateral ESP block seems to be promising, easy to administer, and an acceptable alternative to the epidural catheter (the gold standard in the management of analgesia for thoracic surgery), providing adequate and opiate-free analgesia.
Resumen Introducción: El bloqueo erector de la espina (ESP) es un bloqueo interfascial relativamente nuevo, sobre el cual se han descrito diferentes aplicaciones, tanto en cirugías abdominales como torácicas. Presentación del caso: Paciente de 17 años programado para el retiro de una barra de Nuss por minitoracotomía, a quien, después de la inducción anestésica, se le realizó un bloqueo ESP bilateral guiado con ecografía, y en su posoperatorio inmediato y seguimiento a las 48 horas no reportó dolor alguno. Conclusión: El bloqueo ESP bilateral parece ser prometedor, de fácil realización y apunta a ser una alternativa aceptable al catéter epidural (estándar de oro en el manejo analgésico en cirugías de tórax), por la cual se obtiene analgesia adecuada y libre de opioides.

Abstract Augmentation mammoplasty is the third most frequently performed esthetic surgical procedure worldwide. Breast augmentation with prosthetic implants requires the insertion of an implant under breast tissue, which causes severe pain due to tissue extension and surgical trauma to separated tissues. In this case series, we present the successful pain management of six patients with ultrasound-guided Erector Spinae Plane block after augmentation mammoplasty. In the operating room, all patients received standard monitoring. While the patients were sitting, the anesthesiologist performed bilateral ultrasound-guided erector spinae plane block at the level of T5. Bupivacaine (0.25%, 20 mL) was injected deep to the erector spinae muscle. Then, induction of anesthesia was performed with propofol, fentanyl, and rocuronium bromide. All patients received intravenous dexketoprofen trometamol for analgesia. The mean operation time was 72.5±6 min and none of the patients received additional fentanyl. The mean pain scores of the patients were 1, 2, 2, and 2 at the postoperative 5th, 30th, 60th and 120th minutes, respectively. At the postoperative 24th hour, the mean Numerical Rating Scale score was 1. The mean intravenous tramadol consumption was 70.8±15.3 mg in the first 24 h. None of the patients had any complications related to erector spinae plane block.
Resumo A mamoplastia de aumento é o terceiro procedimento cirúrgico estético mais feito em todo o mundo. A cirurgia com implantes protéticos requer a inserção de um implante sob o tecido mamário, o que causa dor intensa devido à extensão do tecido e trauma cirúrgico aos tecidos separados. Nesta série de casos, apresentamos o manejo bem-sucedido da dor em seis pacientes com bloqueio do plano eretor da espinha guiado por ultrassom (US-ESP) após mamoplastia de aumento. Na sala de cirurgia, todas as pacientes receberam monitoramento padrão. Enquanto as pacientes estavam sentadas, o anestesiologista fez o bloqueio US-ESP bilateral no nível de T5. Bupivacaína (0,25%, 20 mL) foi injetada entre os músculos romboide maior e eretor da espinha. Em seguida, a indução anestésica foi feita com propofol, fentanil e rocurônio. Todas as pacientes receberam dexcetoprofeno trometamol por via venosa para analgesia. O tempo médio de operação foi de 72,5 ± 6 minutos e nenhuma das pacientes recebeu fentanil adicional. Os escores médios de dor das pacientes foram 1, 2, 2 e 2 no 5°, 30°, 60° e 120° minutos de pós-operatório, respectivamente. No 24° dia de pós-operatório, o escore médio da Escala de Avaliação Numérica (NRS) foi 1. O consumo médio de tramadol foi de 40 ± 33,4 mg nas primeiras 24 horas. Nenhuma das pacientes apresentou complicações relacionadas ao bloqueio US-ESP.

A principal finalidade do método Pilates é desenvolver uma automação dos músculos do core. Sendo assim, o objetivo deste estudo foi analisar a razão eletromiográfica dos músculos Oblíquo Interno (OI) e Reto do Abdômen (RA) localizados na parte anterior do tronco, a razão eletromiográfica dos músculos Multífido (MU) e Longuíssimo do Tórax (LO) localizados na parte posterior do tronco, e também a razão ântero-posterior (A/P=RA+IO/LO+MU) desses músculos durante o exercício swan do método Pilates, realizado sobre a Wunda Chair. Na comparação entre as três razões, foram encontradas diferenças estatísticas (p = 0,0103), apenas entre as razões ântero-posterior (A/P), e entre a razão dos músculos localizados na parte posterior do tronco (MU/LO). Os resultados demonstraram que houve um predomínio na atividade eletromiográfica dos músculos da região posterior em relação aos músculos da região anterior do tronco e que os músculos estabilizadores apresentaram maior atividade eletromiográfica em comparação com os músculos globais ou mobilizadores. O exercício swan pode ser utilizado como forma de treinamento para a musculatura do tronco, e como consequência gerar maior estabilidade a coluna vertebral, pois o exercício prioriza a diminuição da carga sobre a coluna vertebral.

The main purpose of the Pilates method is to develop an automation of core muscles. Thus, the aim of this study was to analyze the electromyographic ratio of the Internal Oblique (IO) and Rectus Abdominis (RA) muscles located in the anterior part of the trunk, the electromyographic ratio of the Multifidus (MU) and Longissimus Thoracis (LO) muscles, located in the posterior part of the trunk, and also the ratio antero- posterior (A/P=RA+IO/LO+MU) of these muscles during the swan exercise of the Pilates, performed on the Wunda Chair. In the comparison between the three ratios, statistical differences (p = 0.0013) were found only between the antero-posterior (A/P) ratios and the ratio of the muscles located in the posterior part of the trunk (MU/LO). The results showed a predominance of the electromyographic activity in the muscles of the posterior region in relation to the muscles of the anterior region of the trunk. The stabilizing muscles presented greater electromyographic activity in comparison to the global or mobilizing muscles. The swan can be used as training for the trunk muscles, and therefore generates greater stability of the spine, since exercise prioritizes the decrease of the load on the spine. (AU)

Abstract Background and objective: Erector spinae plane block is a valid technique to provide simultaneously analgesia for combined thoracic and abdominal surgery. Case report: A patient underwent open esophagectomy followed by reconstructive esophagogastroplasty but refused thoracic epidural analgesia; a multi-modal analgesia with a multiple erector spinae plane block was then planned. Three erector spinae plane catheters (T5 and T10 on the right side and T9 on the left side) for continuous analgesia were placed before surgery. During the first 48 h pain was never reported in the thoracic area but the patient reported multiple times to feel a pain well localized in epigastrium, but never localized in any other abdominal quadrant. Discussion: Erector spinae plane block is a valid technique to provide analgesia simultaneously for combined thoracic and abdominal surgery and could be a valid alternative strategy if the use of epidural analgesia is contraindicated.
Resumo Justificativa e objetivo: O bloqueio do plano do eretor da espinha é uma técnica válida para fornecer analgesia em cirurgias combinadas, torácica e abdominal, de modo simultâneo. Relato de caso: Um paciente foi submetido à esofagectomia aberta seguida de esofagogastroplastia reconstrutiva, mas recusou analgesia peridural torácica; uma analgesia multimodal com o bloqueio dos múltiplos segmentos do eretor da espinha foi então planejada. Três cateteres foram colocados no plano do eretor da espinha (T5 e T10 no lado direito e T9 no lado esquerdo) para analgesia contínua antes da cirurgia. Durante as primeiras 48 horas, não houve queixa de dor na área torácica, mas várias vezes o paciente relatou sentir uma dor bem localizada no epigástrio, mas nunca localizada em qualquer outro quadrante abdominal. Discussão: O bloqueio do plano do eretor da espinha é uma técnica válida para fornecer analgesia de modo simultâneo em cirurgias combinadas - torácica e abdominal - e pode ser uma estratégia opcional também válida nos casos em que o uso de analgesia peridural for contraindicado.
