Cirugía esofágica pediátrica. La historia de la cirugía de la atresia esofágica / Pediatric esophageal surgery. The history of esophageal atresia surgery

Introducción. Una de las anomalías congénitas a las que permanentemente se enfrenta el cirujano pediatra es la atresia de esófago. Los resultados de su tratamiento en el siglo XXI, el cual incluso se realiza a través de cirugía mínimamente invasiva, nada tienen que ver con las angustias vividas a partir de su reconocimiento como enfermedad en 1670 por Durston. Métodos. Se realizó una revisión histórica y el análisis de la información disponible en las bases de datos, con el fin de establecer la evolución de la corrección quirúrgica de la atresia esofágica a través del tiempo hasta la actualidad. Resultados. Desde finales del siglo XIX, cuando empezó la era de la cirugía, los cirujanos se enfrentaron a las incertidumbres de una enfermedad que estaba por comprenderse, realizando múltiples esfuerzos infructuosos, con alta mortalidad en cada procedimiento que se proponía para su resolución. Luego de cinco décadas de intentos fallidos, la resiliencia de los cirujanos de la época, junto con el progreso en cuanto a recursos anestésicos, cuidados pediátricos y de enfermería, instrumental y control de las infecciones, permitió que por fin el objetivo de alcanzar la supervivencia después de un procedimiento tan complejo fuera posible. Conclusiones. Este artículo pretende reconocer los hitos que marcaron los avances en la cirugía para la corrección de la atresia de esófago en el ámbito mundial, latinoamericano y nacional.

Introduction. One of the congenital anomalies that pediatric surgeons constantly face is esophageal atresia. The results of its treatment in the 21st century, which is even carried out through minimally invasive surgery, have nothing to do with the anguish experienced after its recognition as a disease in 1670 by Durston. Methods. A historical review and analysis of the information available in the databases was performed to establish the evolution of the surgical correction of esophageal atresia over time to the present. Results. Since the end of the 19th century, when the era of surgery began, surgeons faced the uncertainties of a disease that was yet to be understood, making multiple unsuccesful efforts, with high mortality in each procedure proposed for its resolution. After five decades of failed attempts, the resilience of the surgeons of the time, together with progress in anesthetic resources, pediatric and nursing care, instruments and infection control, finally allowed the goal of achieving survival after such a complex procedure was possible. Conclusions. This article aims to recognize the milestones that marked advances in surgery for the correction of esophageal atresia at the global, Latin American and national levels.

Neumatocele en paciente pediátrico. ¿Cuándo debemos actuar? / Pneumatocele in a pediatric patient. When should we act?

El neumatocele es una lesión cavitada llena de aire de carácter adquirido que se encuentra en el interior del parénquima pulmonar. Aunque las causas pueden variar, el origen infeccioso bacteriano es lo más frecuente. Los cambios en los serotipos de neumococo y el aumento de las neumonías necrotizantes observado en las últimas décadas hacen de este tipo de lesiones algo cada vez más frecuente. Es importante conocer la evolución esperable, así como también saber qué paciente se beneficia de intervención para evitar secuelas a largo plazo y complicaciones graves. En este artículo se exponen las causas, epidemiología, orientación diagnóstica y una propuesta de manejo para el neumatocele.

A pneumatocele is an air-filled cavitary lesion of acquired nature located within the pulmonary parenchyma. Although causes can vary, bacterial infectious origin is the most common. Changes in pneumococcal serotypes and the increase in necrotizing pneumonia observed in recent decades have made these lesions increasingly frequent. It is important to know the expected evolution and to identify which patients would benefit from intervention to prevent long-term sequelae and severe complications. This article exposes the causes, epidemiology, diagnostic approach, and a management proposal for pneumatocele.

Sihler's Staining of the Thoracic Cutaneous Nerve and its Significance / Tinción de Sihler del Nervio Cutáneo Torácico y su Relevancia

SUMMARY: Our team has modified Sihler's intramuscular nerve staining method to allow for calculation of nerve density. Therefore, this study aimed to show the overall distribution pattern of the thoracic cutaneous nerves to provide a morphological basis for selecting and matching sensory reconstruction during skin flap transplantation. Twelve Chinese adult cadavers were dissected; the thoracic skin was removed, and the modified Sihler's staining method was performed. Centered around the nipple, the chest skin was divided into four regions: medial-superior, lateral-superior, lateral-inferior, and medial-inferior. The thoracic skin was not only innervated by the branches of the 1st to 7th intercostal and supraclavicular nerves, but also by a small number of nerves that directly reached the skin and passed through the pectoralis major muscle. There is a phenomenon of cross overlap between the branches of adjacent intercostal nerves. The branches of the 2nd to 7th intercostal nerves were distributed in the breast, and the branches of the lateral and anterior cutaneous branches were densely distributed around the nipple, forming a grid-like anastomosis. There was no cross-overlapping innervation between the anterior cutaneous branches on both sides. The density of nerve distribution in the four regions of the chest was in the order of the medial-superior, lateral-superior, lateral-inferior and medial-inferior region, respectively. These results may be used to map sensory regions when designing thoracic skin flaps for reconstruction surgery to obtain improved sensory recovery.

Nuestro equipo ha modificado el método de tinción nerviosa intramuscular de Sihler para permitir el cálculo de la densidad nerviosa. Por lo tanto, este estudio tuvo como objetivo mostrar el patrón de distribución general de los nervios cutáneos torácicos proporcionando una base morfológica para seleccionar y combinar la reconstrucción sensorial durante el trasplante de colgajo de piel. Se diseccionaron 12 cadáveres de individuos adultos chinos. Se eliminó la piel torácica y se realizó el método de tinción de Sihler modificado, centrada alrededor del pezón, la piel del pecho se dividió en cuatro regiones: medial- superior, lateral-superior, lateral-inferior y medial-inferior. La piel torácica no solo estaba inervada por los ramos de los nervios intercostal y supraclavicular 1º a 7º, sino también por un pequeño número de nervios que llegaban directamente a la piel y pasaban a través del músculo pectoral mayor. Existe un fenómeno de superposición cruzada entre los ramos de los nervios intercostales adyacentes. Los ramos de los nervios intercostales 2º a 7º se distribuyeron en la mama, y los ramos de los ramos cutáneos lateral y anterior se distribuyeron densamente alrededor del pezón, formando una anastomosis en forma de rejilla. No hubo inervación cruzada entre los ramos cutáneos anteriores en ambos lados. La densidad de la distribución nerviosa en las cuatro regiones del tórax estaba en el orden de región medial-superior, lateral-superior, lateral-inferior y medial-inferior, respectivamente. Estos resultados pueden ser útiles para mapear regiones sensoriales al diseñar colgajos de piel torácicos para utilizarlos en cirugía de reconstrucción y obtener así una mejor recuperación sensorial.

Síndrome de dolor crónico posterior a cirugía torácica: estrategias para reducir su incidencia / Chronic pain síndrome after thoracic surgery: strategies to reduce its incidence

El dolor crónico posterior a cirugía torácica es una entidad frecuente, pudiendo llegar a afectar a un 60% de los pacientes sometidos a este tipo de cirugías, con el consiguiente deterioro en su calidad de vida. El principal factor de riesgo para la aparición de éste es la presencia y severidad del dolor agudo postquirúrgico; por lo cual, es de vital importancia la prevención y el tratamiento eficaz de este último. Es por esta razón que la implementación de estrategias para el manejo del dolor agudo, tales como la analgesia multimodal y la analgesia preventiva, juegan un rol importante en el manejo de estos pacientes. Dentro del manejo podemos destacar también el uso de técnicas de analgesia neuroaxial, como la analgesia epidural torácica y técnicas de analgesia regionales, como el bloqueo paravertebral, bloqueos intercostales y los bloqueos del plano o miofascial. La analgesia regional ha cobrado gran interés en los últimos años debido a una eficacia comparable a la anestesia epidural torácica, pero con menos efectos adversos y complicaciones. Finalmente, el uso adecuado y criterioso de las técnicas antes señaladas permitirán un manejo exitoso de nuestros pacientes.

Chronic pain after thoracic surgery is a frequent entity, affecting up to 60% of patients undergoing this type of surgery, with the consequent deterioration in their quality of life. The main risk factor for the appearance of this is the presence and severity of acute post-surgical pain; Therefore, the prevention and effective treatment of the latter is of vital importance. For this reason, the implementation of strategies for the management of acute pain, such as multimodal analgesia and preventive analgesia, play an important role in the management of these patients. Within management we can also highlight the use of neuraxial analgesia techniques, such as thoracic epidural analgesia and regional analgesia techniques such as paravertebral block, intercostal blocks and plane or myofascial blocks. Regional analgesia has gained great interest in recent years due to efficacy comparable to thoracic epidural anesthesia, but with fewer adverse effects and complications. Finally, the proper and judicious use of the techniques will allow a successful management of our patients.

Prevertebral thoracic abscess in neonate- a previously unknown cause of respiratory failure in neonates: a case report

A prevertebral abscess is one of the serious infections of the prevertebral space. Prevertebral abscess cases are reported in children and adults. However, it has not been reported in neonates to date, and our team report a case of prevertebral abscess in a 17-day-old baby. A previously healthy term neonate with no antecedent risk factors and an evident source of infection presented with respiratory failure and repeated extubation failures. On evaluation, bronchoscopy revealed antero-posterior collapse of the trachea; further evaluation by computed tomography scan revealed a prevertebral thoracic abscess which was compressing the trachea. Surgical drainage and IV antibiotics led to complete resolution, and the neonate is doing well on follow-up. Prevertebral thoracic abscess is an uncommon cause of airway compression in the neonates. It is important to consider in the differential diagnosis of airway compression.

Pott’s paraplegia-satisfactory outcome in spite of poor prognostic factors, treated by a novel surgical technique of posterior spinal stabilization and anterolateral decompression with bone graft fusion: a case report

A case of Pott’s paraplegia of sudden onset and of more than two months duration in an aged female, treated by a novel surgical technique of anterior decompression and local kyphotic angle correction by spinal pedicular fixation is presented here. A 52 year female with Pott’s paraplegia, ASIA-A with sphincters involvement and with flexor spasm, was treated by surgical intervention, in a single operation of two stages, the first by provisional posterior pedicular fixation and the second stage by anterolateral decompression and correcting the local kyphotic angle by cyclic changing the rods in increments of 5 degrees in compressive mode. The paravertebral abscess of opposite side was sucked out and at the end a tricortical bone graft harvested from iliac crest was impacted in between the space created by pedicular fixation maneuver in course of correcting kyphosis. There was steady dramatic improvement of clinical and neurological status within three weeks. Kyphotic correction was maintained with anterior tricortical interbody bone graft impacted in position. The novel surgical technique that is adopted for decompression, drainage including paravertebral abscess of opposite side, debridement and local kyphotic angle correction along with interbody bone graft fusion, in this case, offered a satisfactory outcome in spite of poor prognostic factors.

Condrossarcoma gigante de corpo esternal: relato de caso / Giant chondrosarcoma of the sternal body: case report

Os tumores de parede torácicas são relativamente inusitados, representando 1 a 2% de todas as neoplasias, e cerca de 5% das neoplasias torácicas. Sarcomas são tumores raros e com apresentação heterogênea. São divididos em dois grandes grupos: tumores ósseos e de partes moles. A ocorrência na parede torácica é rara, representando 8% de todos os sarcomas. O tratamento de escolha é a ressecção com margens ampliadas e, quando ocorre a invasão de estruturas profundas, a toracectomia é indicada. A reconstrução do arcabouço ósseo é realizada com materiais de síntese, proporcionando estabilidade, e é seguida da reconstrução de partes moles com retalhos musculares, musculocutâneos ou locais ao acaso. Os tumores malignos primários da parede torácica correspondem a menos de 1% de todas as neoplasias e incluem grande variedade de lesões ósseas e de tecidos moles. Os condrossarcomas representam 20% dos tumores primários da parede torácica, sendo que 80% têm origem nas costelas e 20% no esterno.

Chest wall tumors are relatively uncommon, representing 1 to 2% of all neoplasms, and approximately 5% of thoracic neoplasms. Sarcomas are rare tumors with heterogeneous presentation. They are divided into two large groups: bone and soft tissue tumors. Occurrence in the chest wall is rare, representing 8% of all sarcomas. The treatment of choice is resection with wide margins and, when invasion of deep structures occurs, thoracotomy is indicated. The reconstruction of the bone framework is carried out with synthetic materials, providing stability, and is followed by the reconstruction of soft tissues with muscular, musculocutaneous, or random local flaps. Primary malignant tumors of the chest wall account for less than 1% of all neoplasms and include a wide variety of bone and soft tissue lesions. Chondrosarcomas represent 20% of primary tumors of the chest wall, with 80% originating in the ribs and 20% in the sternum.

A Calcificação do Arco Aórtico Observada na Radiografia de Tórax Pode Servir Como um Preditor Independente de Acidente Vascular Cerebral Recorrente / Aortic Arch Calcification Observed on Chest X-Ray May Serve as an Independent Predictor for Recurrent Stroke

Resumo Fundamento Apesar dos avanços nas modalidades de diagnóstico e tratamento, há necessidade de marcadores preditivos para acidente vascular cerebral (AVC) recorrentes. Objetivos Este estudo teve como objetivo investigar a relação entre calcificação do arco aórtico (CAA) e recorrência de AVC em pacientes com AVC durante o acompanhamento de um ano. Métodos Todos os pacientes com AVC que sofreram seu primeiro evento foram avaliados para participação no estudo. Foram registrados pacientes que sofreram AVC recorrentes durante o acompanhamento de um ano. A CAA foi avaliada por radiografia de tórax. Com base na ocorrência de AVC recorrente, os pacientes foram divididos em dois grupos. A CAA foi classificada em quatro categorias de acordo com o seu grau, e a presença de CAA foi incluída na análise estatística. A relação entre CAA e AVC recorrente foi avaliada por meio de uma curva característica de operação do receptor. Um nível de significância <0,05 foi considerado aceitável para todas as análises estatísticas. Resultados Um total de 203 pacientes foram incluídos no estudo (46,8% mulheres, média de idade 69±12,3). AVC recorrente foi detectado em 49 pacientes. CAA, hipertensão e fibrilação atrial foram mais frequentes em pacientes com AVC recorrente. Pacientes com AVC recorrente apresentaram menor taxa de filtração glomerular e maior largura de distribuição de glóbulos vermelhos (RDW). Na análise de regressão multivariada, CAA (hazard ratio [HR], 3,544; IC 95%:1,653-7,598, p=0,001) e RDW (HR,1,214; IC 95%:1,053-1,400, p=0,008) foram identificados como preditores independentes de AVC recorrente. Conclusão A presença de CAA (≥ grau 1) e RDW foram significativamente associadas ao desenvolvimento de AVC recorrente dentro de um ano. Esses achados podem ter significado prognóstico no acompanhamento de pacientes com AVC.

Abstract Background Despite advances in diagnostic and treatment modalities, there is a need for predictive markers for recurrent strokes. Objectives This study aimed to investigate the relationship between aortic arch calcification (AAC) and stroke recurrence in stroke patients during a one-year follow-up. Methods All stroke patients who experienced their first event were evaluated for participation in the study. Patients who experienced recurrent strokes during the one-year follow-up were recorded. AAC was assessed by chest radiography. Based on the occurrence of recurrent strokes the patients were divided into two groups. AAC was classified into four categories according to its degree, and the presence of AAC was included in the statistical analysis. The relationship between AAC and recurrent stroke was assessed using a receiver operating characteristic curve. A significance level of <0.05 was deemed acceptable for all statistical analyses. Results A total of 203 patients were included in the study (46.8% female, mean age 69±12.3). Recurrent stroke was detected in 49 patients. AAC, hypertension, and atrial fibrillation were more frequent in patients with recurrent stroke. Patients with recurrent stroke had a lower glomerular filtration rate and a higher red cell distribution width (RDW). In multivariate regression analysis, AAC (hazard ratio [HR], 3.544; 95% CI:1.653-7.598, p=0.001) and RDW (HR,1.214; 95% CI:1.053-1.400, p=0.008) were identified as independent predictors of recurrent stroke. Conclusion The presence of AAC (≥ grade 1) and RDW were found to be significantly associated with the development of recurrent stroke within one year. These findings may have prognostic significance in the follow-up of stroke patients.

Correlation between postoperative cardiac risks factors, functionality and hospital length of stay / Correlação entre os fatores de risco cardíaco pós-operatórios, funcionalidade e tempo de internação

INTRODUÇÃO: Cardiac surgery (CS) may be associated with several organic repercussions responsible for the appearance of cardiac risk factors during the postoperative period. These, associated with prolonged hospital length of stay (LoS), may trigger critical manifestations in individuals undergoing this surgical procedure. OBJECTIVE: To investigate the relationships between postoperative cardiac risk factors, LoS, and changes in functioning state. METHODS: Patients undergoing reconstructive, substitutive, or corrective cardiac surgeries were evaluated. The presence of postoperative cardiovascular risks was assessed using the InsCor score, while LoS and functionality were collected from medical records. RESULTS: One-hundred patients with a mean age of 59.2±12.3 years were included. Significant correlations between functionality and both the hospital and Intensive Care Unit (ICU) LoS (p<0.0001, ρ=0.56; p=0.002, ρ=0.29, respectively), as well as between hospital LoS and the number of comorbidities (p=0.003, ρ=0.28) were found. No significant relationships were observed between the number of postoperative risk factors and LoS. CONCLUSION: Functionality and comorbidities are associated with increased hospital and ICU LoS in patients undergoing cardiac surgery.

INTRODUÇÃO: A cirurgia cardíaca (CC) pode estar associada a diversas repercussões orgânicas responsáveis pelo surgimento de fatores de risco cardíaco no pós-operatório.

O Índice de Imuno Inflamação Sistêmica Prevê Mortalidade Hospitalar em Pacientes Submetidos à Cirurgia Cardíaca com Circulação Extracorpórea / The Systemic Immune-Inflammation Index Predicts In-Hospital Mortality in Patients Who Underwent On-Pump Cardiac Surgery

Resumo Fundamento: O índice de imuno-inflamação sistêmica (SII), um novo índice inflamatório calculado usando contagens de plaquetas, neutrófilos e linfócitos, demonstrou ser um fator de risco independente para a identificação de doença arterial coronariana de alto risco em pacientes submetidos a intervenção coronária percutânea e cardiovascular e cirurgia com circulação extracorpórea (CEC). A relação entre as taxas de mortalidade relacionadas ao SII e à CEC permanece obscura. Objetivo: Esta pesquisa foi desenhada para investigar o uso do SII para prever mortalidade hospitalar em pacientes submetidos à cirurgia cardíaca com CEC. Métodos: Quatrocentos e oitenta pacientes submetidos a procedimento cardíaco envolvendo CEC durante 3 anos foram coletados do banco de dados do hospital. Foram comparados os dados demográficos, comorbidades, perfis hematológicos e bioquímico e dados operatórios dos grupos. Análises múltiplas de regressão logística foram feitas para determinar preditores independentes de mortalidade. Os fatores prognósticos foram avaliados por análise multivariada e os valores preditivos de SII, relação neutrófilo-linfócito (NLR) e razão plaqueta-linfócito (PLR) para mortalidade foram comparados. Um valor de p <0,05 foi considerado significativo. Resultados: Dos 480 pacientes, 78 desenvolveram mortalidade hospitalar após cirurgia cardíaca. O SII foi um preditor independente de mortalidade hospitalar (odds ratio: 1,003, intervalo de confiança de 95%: 1,001-1,005, p<0,001). O valor de corte do SII foi >811,93 com sensibilidade de 65% e especificidade de 65% (área sob a curva: 0,690). Os valores preditivos de SII, PLR e NLR foram próximos entre si. Conclusão: Altos escores pré-operatórios do SII podem ser usados para determinação precoce de tratamentos apropriados, o que pode melhorar os resultados cirúrgicos de cirurgia cardíaca no futuro.

Abstract Background: Systemic immune-inflammation index (SII), a new inflammatory index calculated using platelet, neutrophil, and lymphocyte counts, has been demonstrated to be an independent risk factor for the identification of high-risk coronary artery disease in patients undergoing percutaneous coronary intervention and cardiovascular surgery with cardiopulmonary bypass (CPB). The relationship between SII and CPB-related mortality rates remains unclear. Objective: This research was designed to investigate the use of SII to predict in-hospital mortality in patients undergoing cardiac surgery with CPB. Methods: Four hundred eighty patients who underwent a cardiac procedure involving CPB over 3 years, were obtained from the hospital's database. The demographic data, comorbidities, hematological and biochemical profiles, and operative data of the groups were compared. Multiple logistic regression analyses were done to determine independent predictors of mortality. Prognostic factors were assessed by multivariate analysis, and the predictive values of SII, neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR) for mortality were compared. A p-value <0.05 was considered significant. Results: Of 480 patients, 78 developed in-hospital mortality after cardiac surgery. SII was an independent predictor of in-hospital mortality (Odds ratio: 1.003, 95% confidence interval: 1.001-1.005, p<0.001). The cut-off value of the SII was >811.93 with 65% sensitivity and 65% specificity (area under the curve: 0.690). The predictive values of SII, PLR, and NLR were close to each other. Conclusion: High preoperative SII scores can be used for early determination of appropriate treatments, which may improve surgical outcomes of cardiac surgery in the future.

Study on Analgesic Effects of Combined Thoracic Paravertebral Block Anesthesia or Erector Spinae Plane Block with Ultrasound Guided Transversus Abdominis Plane Block in Endoscopic Esophagectomy: A Clinical Anatomical Approach / Estudio sobre los Efectos Analgésicos de la Anestesia Combinada con Bloqueo Paravertebral Torácico o el Bloqueo del Plano del Erector de la Columna con Bloqueo del Plano Transverso del Abdomen Guiado por Ultrasonido en la Esofagectomía Endoscópica: Un Enfoque Anatómico Clínico

SUMMARY: The application effect of transversus abdominis plane block (TAPB) combined with thoracic paravertebral block (TPVB) or erector spinae plane block (ESP) under ultrasound guidance in endoscopic radical resection of esophageal cancer under general anesthesia was studied. From March 2021 to February 2022, patients who underwent endoscopic radical resection of esophageal cancer in our hospital were selected as the research object, and 90 patients were selected as the samples. Patients were divided into groupA and group B according to the difference of blocking schemes. Group A received ESP and Group B received TPVB. The dosage of sufentanil, nerve block time, awakening time and extubation time of the two groups were counted. The postoperative pain, sedation effect, sleep satisfaction and analgesia satisfaction of the two groups were compared, and the complications of the two groups were observed. The nerve block time and extubation time in group A were shorter than those in group B (P0.05). At T2, T3 and T4, the visual analogue scale (VAS) scores of group A at rest and cough were significantly lower than those of group B (P0.05). The satisfaction of sleep and analgesia in group A was higher than that in group B (P0.05). The analgesic effect of ultrasound-guided TAPB combined with ESP is better than that of ultrasound-guided TAPB combined with TPVB, and it can shorten the time of nerve block and extubation, which is worth popularizing.

Se estudió el efecto de la aplicación del bloqueo del plano transverso del abdomen (TAPB) combinado con el bloqueo paravertebral torácico (TPVB) o el bloqueo del plano del erector de la columna (ESP) bajo guía ecográfica en la resección radical endoscópica del cáncer de esófago bajo anestesia general. Desde marzo de 2021 hasta febrero de 2022, en nuestro hospital, se seleccionaron como objeto de investigación pacientes sometidos a resección radical endoscópica de cáncer de esófago, y como muestra se seleccionaron 90 pacientes. Los pacientes se dividieron en el grupo A y el grupo B según la diferencia de esquemas de bloqueo. El grupo A recibió ESP y el grupo B recibió TPVB. Se contaron la dosis de sufentanilo, el tiempo de bloqueo nervioso, el tiempo de despertar y el tiempo de extubación de los dos grupos. Se compararon el dolor posoperatorio, el efecto de la sedación, la satisfacción del sueño y la satisfacción de la analgesia de los dos grupos y se observaron las complicaciones de los dos grupos. El tiempo de bloqueo nervioso y el tiempo de extubación en el grupo A fueron más cortos que los del grupo B (P0,05). En T2, T3 y T4, las puntuaciones de la escala visual analógica (EVA) del grupo A en repo- so y tos fueron significativamente más bajas que las del grupo B (P 0,05). La satisfacción del sueño y la analgesia en el grupo A fue mayor que en el grupo B (P0,05). El efecto analgésico de la TAPB guiada por ecografía combinada con ESP es mejor que el de la TAPB guiada por ecografía combinada con TPVB, y puede acortar el tiempo de bloqueo nervioso y extubación, lo que vale la pena popularizar.

Objetivo: Analisar a atuação do enfermeiro perfusionista na cirurgia cardíaca. Método: Estudo exploratório com abordagem qualitativa, desenvolvida em ambiente virtual no período de 1 a 30 de junho de 2022. Amostra intencional, não probabilística, constituída de 14 enfermeiros perfusionistas. Os dados foram analisados por meio da análise de conteúdo de Bardin. Resultados: Emergiram duas categorias temáticas: Atuação do enfermeiro perfusionista na circulação extracorpórea e A relevância da interação do enfermeiro com os membros da equipe durante a cirurgia cardíaca com circulação extracorpórea. Os relatos identificaram que o enfermeiro perfusionista realiza inúmeras atribuições que vão desde o histórico de enfermagem, até o preparo e a escolha de materiais, circuitos, dispositivos e maquinários para a condução da circulação extracorpórea. Destaca-se a interação desse profissional com os demais membros da equipe no tocante à comunicação a fim de minimizar riscos e obter resultado cirúrgico positivo para o paciente. Conclusão: A atividade do enfermeiro perfusionista é complexa e necessita de um rigoroso preparo teórico-prático, especializações reconhecidas pelos órgãos competentes, bem como frequentes atualizações mesmo já sendo um profissional experiente. (AU)

Objective: To analyze the role of the perfusionist nurse in cardiac surgery. Method: Exploratory study with a qualitative approach, conducted in a virtual environment from June 1st to June 30th, 2022. The sample consisted of 14 perfusionist nurses, selected intentionally and non-probabilistically. Data were analyzed through Bardin's content analysis. Results: Two thematic categories emerged: the role of the perfusionist nurse in extracorporeal circulation and the relevance of the nurse's interaction with team members during cardiac surgery with extracorporeal circulation. The reports identi-fied that the perfusionist nurse performs numerous tasks ranging from nursing history to the preparation and selection of materials, circuits, devices, and machinery for extracorporeal circulation. The interaction of this professional with other team members regarding communication stands out, aiming to minimize risks and achieve positive surgical outcomes for the patient.

Lesión cardíaca por arma blanca inadvertida durante la evaluación inicial en el servicio de emergencia / Missed cardiac stab injury during initial evaluation in the Emergency Department

Introducción. La incidencia reportada de traumatismo cardíaco es baja y su grado de resolución es variable, dependiendo de la causa, el mecanismo de la lesión, el lugar donde ocurra y las características del sistema sanitario. Su incidencia ha aumentado recientemente debido al incremento de los accidentes de tránsito y la violencia, predominando los traumatismos penetrantes asociados a heridas por armas cortopunzantes y de fuego. Los traumatismos cardíacos se acompañan de un alto grado de letalidad. Caso clínico. Mujer de 35 años que consultó a emergencia por trauma torácico penetrante ocasionado por arma blanca y fue intervenida de urgencia por derrame pleural izquierdo, sin mejoría hemodinámica. Fue reevaluada detectándose derrame pericárdico con taponamiento cardíaco, ocasionado por lesión cardíaca. Fue tratada quirúrgicamente con resultados satisfactorios. Resultados. Las manifestaciones clínicas en los traumatismos penetrantes generalmente son graves y fatales, pero en algunos casos puede no comprometer tanto la hemodinamia del paciente. Para consolidar el diagnóstico clínico pueden realizarse variados estudios, siendo la ecografía FAST extendida uno de los más recomendados por su elevada sensibilidad y especificidad. Dependiendo del adelanto tecnológico del centro hospitalario y la estabilidad hemodinámica del paciente, el tratamiento quirúrgico es el más indicado. Conclusión. El conocimiento del trauma cardíaco penetrante resulta de gran importancia, no solo para el médico del servicio de emergencia sino también para el médico general. Un diagnóstico rápido y acertado, unido a un manejo adecuado, pueden ser decisivos para salvar la vida del paciente.

Introduction. The reported incidence of cardiac trauma is low and its degree of resolution is variable depending on the cause, the mechanism of injury, the place where it occurs and the characteristics of the health care system. Their incidence has currently increased due to the increase in traffic accidents and violence, with a predominance of penetrating trauma associated with stab wounds and firearms. Cardiac trauma is accompanied by a high degree of lethality. Clinical case. A 35-year-old female patient, evaluated in the emergency room for penetrating thoracic trauma caused by stab wound. She underwent emergency intervention due to left pleural effusion, but without hemodynamic improvement. She was reevaluated and pericardial effusion with cardiac tamponade caused by cardiac injury was detected. She was treated surgically with satisfactory results. Results.The clinical manifestations generally described in penetrating cardiac trauma are severe and fatal, but in some cases and due to the characteristics of the injury caused, the patient's hemodynamics may not be so compromised. To consolidate the clinical diagnosis, several complementary studies can be performed, with FAST ultrasound being one of the most recommended due to its high sensitivity and specificity. Surgical treatment is still the most indicated, depending on the technological progress of the hospital and the hemodynamic stability of the patient. Conclusions.Knowledge of penetrating cardiac trauma is of great importance, not only for the emergency department physician but also for the general practitioner. A quick and accurate diagnosis, together with adequate management can be decisive in saving the patient's life.

Trauma cerrado de aorta torácica, desde el servicio de urgencias hasta el quirófano: revisión narrativa / Blunt trauma of the thoracic aorta, from the emergency department to the operating room: narrative review / Trauma contuso da aorta torácica: do pronto-socorro ao centro cirúrgico, uma revisão narrativa

El trauma es la principal causa de muerte de la población en edad productiva. El abordaje del trauma torácico cerrado todavía es un desafío para el médico de urgencias. Aunque no es una entidad frecuente, se asocia con una alta mortalidad y resultados adversos. El diagnóstico del trauma cerrado de aorta torácica (LCAT) requiere un alto índice de sospecha, dado que los signos y síntomas no son específicos de esta enfermedad (dolor torácico, dolor interescapular, disnea, disfagia, estridor, disfonía). Es importante resaltar que la ausencia de inestabilidad hemodinámica no debe descartar una lesión aórtica. Para su diagnóstico imagenológico se debe tener en cuenta que los rayos X de tórax no tienen el rendimiento adecuado, el patrón de referencia es la angiotomografía y el ecocardiograma transesofágico (ETE) constituye una opción diagnóstica. El manejo incluye líquidos endovenosos y antihipertensivos como medida transitoria, manejo quirúrgico definitivo y, en algunos casos, manejo expectante o diferido. Los pacientes inestables o con signos de ruptura inminente deben ser llevados de manera inmediata a cirugía. El manejo quirúrgico temprano ha impactado en la mortalidad. A pesar de los avances en las técnicas quirúrgicas, la técnica quirúrgica abierta documenta mayor tasa de mortalidad que el manejo endovascular, el cual tiene numerosas ventajas al ser poco invasivo. Esta es una revisión narrativa que destaca algunos aspectos clave sobre los mecanismos de lesión, diagnóstico y manejo inicial del trauma cerrado aorta torácica. Por último, se propone un algoritmo de abordaje de trauma de aorta.

Trauma is the leading cause of death in the productive-age population. Addressing blunt chest trauma is still a challenge for the emergency physician. Although it is not a common entity, it is associated with high mortality and adverse outcomes. The diagnosis of blunt thoracic aortic trauma (LCAT) requires a high index of suspicion, given that the signs and symptoms are not specific to this disease (chest pain, interscapular pain, dyspnea, dysphagia, stridor, dysphonia). It is important to highlight that the absence of hemodynamic instability should not rule out aortic injury. For its imaging diagnosis, it must be taken into account that chest X-rays do not have adequate performance; the reference standard is angiotomography and transesophageal echocardiography (TEE) is a diagnostic option. Management includes intravenous fluids and antihypertensives as a temporary measure, definitive surgical management and, in some cases, expectant or deferred management. Unstable patients or patients with signs of imminent ruptura should be taken immediately to surgery. Early surgical management has impacted mortality. Despite advances in surgical techniques, the open surgical technique documents a higher mortality rate than endovascular management, which has numerous advantages as it is minimally invasive. This is a narrative review that highlights some key aspects about the mechanisms of injury, diagnosis and initial management of blunt thoracic aortic trauma. Finally, an algorithm for addressing aortic trauma is proposed.

O trauma é a principal causa de morte na população em idade produtiva. Abordar o trauma torácico contuso ainda é um desafio para o médico emergencista. Embora não seja uma entidade comum, está associada a alta mortalidade e resultados adversos. O diagnóstico de trauma fechado de aorta torácica (TACE) requer alto índice de suspeição, visto que os sinais e sintomas não são específicos desta doença (dor torácica, dor interescapular, dispneia, disfagia, estridor, disfonia). É importante ressaltar que a ausência de instabilidade hemodinâmica não deve descartar lesão aórtica. Para seu diagnóstico por imagem deve-se levar em consideração que a radiografia de tórax não apresenta desempenho adequado; o padrão de referência é a angiotomografia e a ecocardiografia transesofágica (ETE) é uma opção diagnóstica. O manejo inclui fluidos intravenosos e anti-hipertensivos como medida temporária, manejo cirúrgico definitivo e, em alguns casos, manejo expectante ou diferido. Pacientes instáveis ou com sinais de ruptura iminente devem ser encaminhados imediatamente para cirurgia. O manejo cirúrgico precoce impactou a mortalidade. Apesar dos avanços nas técnicas cirúrgicas, a técnica cirúrgica aberta documenta maior taxa de mortalidade do que o manejo endovascular, que apresenta inúmeras vantagens por ser minimamente invasivo. Esta é uma revisão narrativa que destaca alguns aspectos-chave sobre os mecanismos de lesão, diagnóstico e manejo inicial do trauma contuso da aorta torácica. Finalmente, é proposto um algoritmo para tratar o trauma aórtico.

RESUMEN Objetivo: Describir las características clínico-demográficas de sujetos internados luego de una intervención quirúrgica que recibieron asistencia kinésica (AK) en la sala de cirugía general de un hospital público de la Ciudad Autónoma de Buenos Aires (CABA). El objetivo secundario consiste en describir el uso de dispositivos de oxigenoterapia, el desarrollo de complicaciones pulmonares postoperatorias (CPP) y el tiempo transcurrido hasta la AK. Materiales y métodos: Se incluyeron datos extraídos de fichas kinésicas de sujetos que se sometieron a una intervención quirúrgica abdominal, torácica o pélvica y recibieron AK entre enero de 2019 y diciembre de 2022. Se registraron datos demográficos y clínicos, motivo de consulta kinésica, desarrollo de CPP, cantidad de días de AK y uso de dispositivos de oxigenoterapia. Resultados: Se incluyeron 151 fichas kinésicas. Del total, 15 sujetos (9,9 %) desarrollaron CPP. En este grupo, la mediana de días transcurridos entre el procedimiento quirúrgico y el comienzo de la AK fue de 8 días (RIQ 4-16), mientras que para los sujetos que no desarrollaron complicaciones fue de 4 días (RIQ 2-7). Un total de 57 sujetos (37,5 %) requirieron oxigenoterapia, de los cuales 3 requirieron ventilación mecánica invasiva y 1 no invasiva. Conclusión: Se describieron las características clínico-demográficas de sujetos postquirúrgicos internados en la sala de cirugía general de un hospital general de agudos de la CABA. Aquellos sujetos con CPP recibieron más días de AK y requirieron oxígeno suplementario durante un período más extenso. Los sujetos que no desarrollaron CPP recibieron AK en una etapa más temprana, en comparación con los que desarrollaron complicaciones.

ABSTRACT Objective: To describe the clinical-demographic characteristics of subjects who were hospitalized after a surgical intervention and received physical therapy (PT) in the general surgery ward of a public hospital in the Autonomous City of Buenos Aires (CABA). The secondary objective is to describe the use of oxygen therapy devices, the development of postoperative pulmonary complications (PPC), and the time elapsed until PT. Materials y methods: We included data from the PT records of subjects who underwent abdominal, thoracic, or pelvic surgical interventions and received PT between January 2019 and December 2022. Demographic and clinical data, reason for PT consultation, development of PPC, number of days of PT, and use of oxygen therapy devices were recorded. Results: A total of 151 records were included; of them, 15 subjects (9.9 %) developed PPC. In this group, the median number of days elapsed between the surgical intervention and the onset of PT was 8 days (IQR 4-16), while for subjects who did not develop complications, it was 4 days (IQR 2-7). A total of 57 subjects (37.5 %) needed oxygen therapy, with 3 subjects requiring invasive mechanical ventilation and 1 requiring non-invasive mechanical ventilation. Conclusion: We described the clinical-demographic characteristics of postoperative subjects hospitalized in the general surgery ward of a general acute hospital in the CABA. Subjects with PPC received PT over an extended period and required supplemental oxygen for a longer period. Subjects who did not develop PPC received PT earlier, compared with those who developed complications.

Effect of different regional blocks on postoperative acute and chronic pain in patients undergoing modified radical mastectomy / 重庆医学

Objective To compare the effect of serratus anterior plane block(SAPB)and thoracic para-vertebral block(TPVB)on acute and chronic pain and plasma tumor necrosis factor-α(TNF-α)level after breast cancer modified radical operation.Methods A total of 99 patients with elective breast cancer modified radical operation,aged 35-70 years,American Society of Anesthesiologists physical status(ASA):grade Ⅰ-11,Body Mass Index(BMI):18-25 kg/m2,were randomly divided into three groups:the simple patient-con-trolled intravenous analgesia(PCIA)group(C group),PCIA combined with TPVB group(TC group)and PCI A combined witj SAPB group(SC group).TPVB and SAPB were performed before induction in the TC group and the SC group,and the relevant situation of regional blocking operation was recorded.The Visual Analogue Scales(VAS)scores in rest and activity at 2,4,8,12,24,48 h after operation,effective pressing times of analgesic pump and remedial analgesia situation after operation were recorded.The TNF-α levels be-fore anesthesia and at postoperative 12,48 h,in postoperative 3,6 months were measured by enzyme linked immunosorbent assay(ELISA).Results Compared with the TC group,the block operation time in the SC group was shorter(P＜0.05).Compared with the C group,the VAS scores in the state of rest and activity at postoperative 2,4,8,12,24 h in the TC group and SC group were significantly decreased(P＜0.05),and the dosage of remifentanil during operation,incidence rates of postoperative nausea and vomiting,effective press-ing times of analgesic pump and rate of remedial analgesia were all decreased(P＜0.05).There was no statis-tical difference in the incidence rate of post-mastectomy pain syndrome(PMPS)among the three groups(P＞0.05).Compared with the C group,the levels of plasma TNF-α in the TC group and SC group were decreased at postoperative 12,48 h,in postoperative 3,6 months,moreover the VAS score in the patients with PMPS was lower(P＜0.05).Compared with the patients without PMPS occurrence,the levels of plasma TNF-α in postoperative 3,6 months in the patients with PMPS were significantly up-regulated(P＜0.05).Conclusion By blocking the afference of pain signals caused by peripheral injury and reducing plasma TNF-α level,SAPB or TPVB may relieve the acute and chronic pain degree in the patients with breast cancer modified radi-cal operation.
