Correlation between postoperative cardiac risks factors, functionality and hospital length of stay

Introduction: 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.

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.

Objectifs.Evaluer l'apport de la TDM thoracique dans le diagnostic de la COVID-19 chez les patients suspects en prenant comme référence le Test RT ­PCR et secondairement déterminer les anomalies scanographiques caractéristiques associés au Test RT ­PCR.Matériels etméthodes.Il s'est agi d'une étude rétrospective, descriptive à visée analytique, menée au service d'imagerie du CHU de Libreville. Aux vues de la disponibilité des dossiers nous avons exploité ceux de la période d'activité de mars à juin 2020, soit une période quatre mois. Cette étude a inclus tous les patients ayant une infection à COVID-19 confirmée par la réaction de polymérase en chaine en temps réel (RT ­PCR), après écouvillonnages nasal et/ou pharyngé et / ou les signes typiques de la pneumonie à COVID-19. Pour déterminer les anomalies scanographiques caractéristiques de la COVID-19 associées au test RT ­PCR nous avons comparé 25 patients avec un test RT ­PCR négatifs et 119 patients avec un test RT ­PCR positifs. Une valeur de p < 0,05 était considérée comme significative. La sensibilité de la TDM thoracique a été calculée à l'aide de la relation, Sensibilité=VP/ (VP+FN), (VP : vrai positif de la TDM : TDM positive et test RT PCR positif ; et le FN : Faux négatif de la TDM : TDM négative et test RT PCR positif). L'analyse statistique a été rendu possible grâce au logiciel SPSS 25. Résultats. En régression logistique multivariée, les anomalies scanographiques caractéristiques de la COVID-19 positivement associés à un test RT ­PCR positif étaient :verre dépoliOR = 33,236, IC95% [6,939 ­59,192], p=0,0001), la condensation alvéolaire (OR = 8,093 [1,488 ­44,013]; p=0,016). La sensibilité du scanner thoracique pour le diagnostic de la COVID-19, chez les patients suspects était de 93,2%, la spécificité de 64,2% avec une valeur prédictive positive de 90,2% et une valeur prédictive négative de 73,0%.Conclusion.Le diagnostic scanographique de la COVID-19 chez les patients suspects est aisé avec une bonne sensibilité et spécificité. La présence des anomalies scanographiques caractéristiques à type de verre dépoli et de condensation alvéolaire est associéeà un test RT ­PCR positif

Objective. Evaluate the contribution of Thoracic CT in the diagnosis of COVID-19 in suspected patients by taking the RT ­PCR Test as a reference and secondarily determine the impact of the RT ­PCR Test on characteristic scan abnormalities, in the service of thoracic imaging at Libreville University Hospital.Materials and methods. This was a retrospective, descriptive study with an analytical aim. In view of the availability of files, we used those from the period of activity from March to June 2020, i.e. a four-month period. To determine the impact of the RT ­PCR test on characteristic scan abnormalities, we compared 25 patients with negative RT ­PCR and 119 patients with negative RT ­PCR. A value of p < 0.05 was considered significant. The sensitivity of chestCT was calculated using the relationship, Sensitivity=VP/(VP+FN), (VP: true positive of CT: positive CT and positive RT PCR test; and FN: False negative CT: negative CT and positive RT PCR test). Statistical analysis was made possible using SPSS 25 software.Results. In multivariate logistic regression, CT abnormalities characteristic of COVID-19 were positively associated with a positive RT ­PCR: ground glass, (OR = 33.236, 95% CI [6.939 ­59.192], p = 0.0001), condensation alveolar (OR = 8.093 [1.488 ­44.013]; p = 0.016). The sensitivity of chest CT for the diagnosis of COVID-19 in suspected patients was 93.2%, the specificity of 64.2% with a positive predictive value of 90.2% and a negative predictive value of 73. 0%.Conclusion. CT diagnosis of COVID-19 in suspected patients is easy with good sensitivity and specificity. The presence of characteristic scan abnormalities such as ground glass and alveolar condensation is associated with a positive RT ­PCR tes

Diagnosis and treatment of 131 adult patients with bronchopulmonary sequestration: A retrospective analysis / 中国胸心血管外科临床杂志

@#Objective    To explore the safety and feasibility of uni-portal video-assisted thoracic surgery (VATS) for the treatment of bronchopulmonary sequestration (BPS). Methods    The clinical data of BPS patients with surgical resection in Shanghai Pulmonary Hospital from February 2010 to June 2021 were reviewed. The patients were divided into a VATS group and a thoracotomy group according to the operation method. The operation time, intraoperative blood loss, hospital stay and postoperative complication rate were compared between the two groups. The VATS group was subdivided into a uni-portal VATS group and a multi-portal VATS group for subgroup analysis. Results    Finally 131 patients were enrolled, including 62 males and 69 females with an average age of 39.3±13.2 years. There were 103 patients in the VATS group and 28 patients in the thoracotomy group. A total of 104 patients were diagnosed with left lower BPS, 26 with right lower BPS and 1 with bilateral lower BPS. The main symptom was cough (88 patients, 67.2%). There were 119 patients diagnosed by thoracic enhanced CT before operation. Compared with the thoracotomy group, the operation time was not statistically different (P=0.717), but the blood loss was less, the rate of postoperative complication was lower and hospital stay was shorter in the VATS group (P<0.05). The rate of conversion to open surgery in the uni-portal VATS group and multi-portal VATS group was 11.8% and 13.5%, respectively. Meanwhile, patients in the uni-portal VATS group had shorter operation time and postoperative hospital stay, less blood loss and lower postoperative complication rate than those in the multi-portal VATS group (P<0.05). Conclusion     In order to improve the rate of diagnosis, the lung enhanced CT scan should be selected as an optimal noninvasive method in adult suspected patients (especially those with solid cystic and solid lesions in the lower lobe). Uni-portal VATS is a safe and feasible method for BPS which can be widely promoted.

Imaging study on thoracic and lumbar physiological curvature in adolescent idiopathic scoliosis / 中国骨伤

OBJECTIVE@#To observe the alteration of thoracic and lumbar physiological curvature in adolescent idiopathic scoliosis(AIS) and the difference of physiological curvature between different types of scoliosis.@*METHODS@#A retrospective analysis was conducted on 305 adolescent patients taken full spine X-ray in our hospital from January 2017 to December 2021. The patients were divided into normal group and scoliosis group. The normal group was composed of 179 patients, 79 males and 100 females, aged 10 to 18 years old with an average of (12.84±2.10) years old, with cobb agle less than 10 degrees. The scoliosis group was composed of 126 patients, 33 males and 93 females, aged 10 to 18 years old with an average of (13.92±2.20) years old. The gender, age, Risser sign, thoracic kyphosis(TK) and lumbar lordosis(LL) in 2 groups were compared, and the TK and LL were also compared between different genders, different degrees of scoliosis and different segments of scoliosis.@*RESULTS@#The female ratio(P=0.001) and age (P<0.001) in scoliosis group were higher than them in normal group; the ratio of low-grade ossification was higher in normal group than in scoliosis group(P=0.038). TK was significantly smaller in scoliosis group than in normal group(P<0.001), but there was no significant difference in LL between the 2 groups(P=0.147). There were no significant difference in TK and LL between male and female. The TK was significantly bigger in mild AIS patients than in moderate AIS patients(P<0.05), but there was no significant difference in LL between mild and moderate patients(P>0.05). The TK and LL in different segments scoliosis were not found significant difference.@*CONCLUSION@#The physiological curvature of thoracic and lumbar spine is independent of gender. The thoracic physiological curvature becomes smaller in AIS patients, but lumbar curvature remains unchanged. The thoracic physiological curvature in mild AIS patients is greater than that in moderate AIS patients, but the lumbar curvature is almost unchanged between mild and moderate scoliosis and is similar with that in normal adolescent. The alteration of thoracic and lumbar physiological curvature in AIS patients may be related to relative anterior spinal overgrowth, and the specific detailed mechanism needs to be further studied.

Methods This is a controlled and randomized clinical trial carried out in a university reference hospital in cardiology between June and December 2021. Chunk randomization and allocation by draw with opaque sealed envelopes were carried out in two groups: Control (n=44; not subjected to intervention); and Intervention (n=44; submitted to two Reiki sessions three days before and the day before surgery). The main outcomes (anxiety, well-being and muscle tension) were assessed across sessions using a mixed effects model. To assess the effect size, partial eta squared (η2p) values were calculated. Results Differences in anxiety scores (+2.7 points more than the control), well-being (-0.78) and muscle tension (1.27) were determined, being considered statistically significant (p<0.001). In analyzing the effect size, the experiment better distinguished the variation in the anxiety variable (η2p=0.74) than in the other two variables (η2p=0.14; η2p=0.23). Conclusion The study offers favorable evidence for the effectiveness of Reiki in controlling preoperative anxiety after cardiac surgery. Brazilian Clinical Trials Registry: RBR-2nhgvn6

Relação entre a Complacência Pulmonar Estática e a Falha de Extubação em Pacientes Pós-Operatório de Cirurgia Cardíaca / Relationship between Static Lung Compliance and Extubation Failure in Postoperative Cardiac Surgery Patients

Resumo Fundamento: Pouco explorada na decisão de extubação no pós-operatório de cirurgia cardíaca, a complacência pulmonar estática seriamente afetada no procedimento cirúrgico pode levar à insuficiência respiratória e à falha na extubação. Objetivo: Avaliar a complacência pulmonar estática no pós-operatório de cirurgia cardíaca e relacionar sua possível redução aos casos de falha na extubação dos pacientes submetidos ao método fast-track de extubação. Métodos: Foram incluídos pacientes que realizaram cirurgia cardíaca com uso de circulação extracorpórea (CEC) em um hospital universitário estadual admitidos na UTI sob sedação e bloqueio residual. Tiveram sua complacência pulmonar estática avaliada no ventilador mecânico por meio do software que utiliza o least squares fitting (LSF) para a medição. No período de 48 horas após a extubação os pacientes foram observados respeito à necessidade de reintubação por insuficiência respiratória. O nível de significância adotado para os testes estatísticos foi de 5%, ou seja, p<0,05. Resultados: Obtiveram sucesso na extubação 77 pacientes (75,49%) e falharam 25 (24,51%). Os pacientes que falharam na extubação tiveram a complacência pulmonar estática mais baixa quando comparados aos que tiveram sucesso (p<0,001). Identificamos o ponto de corte para complacência por meio da análise da curva Receiver Operating Characteristic Curve (ROC) sendo o ponto de corte o valor da complacência <41ml/cmH2O associado com maior probabilidade de falha na extubação (p<0,001). Na análise de regressão múltipla, verificou-se a influência da complacência pulmonar (dividida pelo ponto de corte da curva ROC) com risco de falha 9,1 vezes maior para pacientes com complacência <41ml/cmH2O (p< 0,003). Conclusões: A complacência pulmonar estática <41ml/cmH2O é um fator que compromete o sucesso da extubação no pós-operatório de cirurgia cardíaca.

Abstract Background: Static lung compliance, which is seriously affected during surgery, can lead to respiratory failure and extubation failure, which is little explored in the decision to extubate after cardiac surgery. Objective: To evaluate static lung compliance in the postoperative period of cardiac surgery and relate its possible reduction to cases of extubation failure in patients submitted to the fast-track method of extubation. Methods: Patients undergoing cardiac surgery using cardiopulmonary bypass (CPB) at a state university hospital admitted to the ICU under sedation and residual block were included. Their static lung compliance was assessed on the mechanical ventilator using software that uses least squares fitting (LSF) for measurement. Within 48 hours of extubation, the patients were observed for the need for reintubation due to respiratory failure. The level of significance adopted for the statistical tests was 5%, i.e., p<0.05. Results: 77 patients (75.49%) achieved successful extubation and 25 (24.51%) failed extubation. Patients who failed extubation had lower static lung compliance compared to those who succeeded (p<0.001). We identified the cut-off point for compliance through analysis of the Receiver Operating Characteristic Curve (ROC), with the cut-off point being compliance <41ml/cmH2O associated with a higher probability of extubation failure (p<0.001). In the multiple regression analysis, the influence of lung compliance (divided by the ROC curve cut-off point) was found to be 9.1 times greater for patients with compliance <41ml/cmH2O (p< 0.003). Conclusions: Static lung compliance <41ml/cmH2O is a factor that compromises the success of extubation in the postoperative period of cardiac surgery.

Prolonged survival after thoracic metastasectomy in patients with nonseminomatous testicular cancer

Abstract Introduction Almost 20 % of patients with Non-Seminomatous Germinative Cell Tumors (NSGCT) will require intrathoracic metastasectomy after chemotherapy. The authors aim to determine their long-term survival rates. Methods Retrospective study including patients with NSGCT and intrathoracic metastasis after systemic therapy from January 2011 to June 2022. Treatment outcomes and overall survival were analyzed with the Kaplan-Meier method. Results Thirty-seven male patients were included with a median age of 31.8 years. Six presented with synchronous mediastinum and lung metastasis, nine had only lung, and 22 had mediastinal metastasis. Over half had retroperitoneal lymph node metastasis. Twenty-two had dissimilar pathologies, with a discordance rate of 62 %. Teratoma and embryonal carcinoma were the prevalent primary tumor types, 40.5 % each, while teratoma was predominant (70.3 %) in the metastasis group. Thoracotomy was the main surgical approach (39.2 %) followed by VATS (37.2 %), cervico-sternotomy (9.8 %), sternotomy (5.8 %), and clamshell (3.9 %). Lung resection was performed in 40.5 % of cases. Overall, 10-year survival rates were 94.3 % with no surgical-related mortality. Conclusion Multimodality treatment with systemic therapy followed by radical surgery offers a high cure rate to patients with intrathoracic metastatic testicular germ cell tumors.

Is Deep Hypothermic Cardiac Arrest Mandatory in Aortic Arch Surgeries?

ABSTRACT Cannulation strategies in aortic arch surgeries are a matter of immense discussion. Majority of time deep hypothermic circulatory arrest (DHCA) is the way out, but it does come with its set of demerits. Here we demonstrate a case with aortic arch dissection dealt with dual cannulation strategy in axillary and femoral artery without need for DHCA and ensuring complete neuroprotection of brain and spinal cord without hinderance of time factor. Inception of new ideas like this may decrease the need for DHCA and hence its drawbacks, thus decreasing the morbidity and mortality associated.

Bone Anatomy of the Thoracic Limb in the Common Hippopotamus (Hippopotamus amphibius) and White Rhinoceros (Ceratotherium simum)

SUMMARY: Although megaherbivores do not belong to the Brazilian fauna, they can be found in national zoos, which makes it important to know the anatomy of the locomotor apparatus to contribute to the clinical routine of zoos and veterinary rehabilitation centers. Thus, the aim of this study was to describe the anatomical structures of the thoracic limb bones in the common hippopotamus (Hippopotamus amphibius) and white rhinoceros (Ceratotherium simum) and to compare them with the bone structures described for other ungulates. The scapula had a triangular appearance in the common hippopotamus, whereas in the white rhinoceros it had a rectangular appearance. The acromion was observed only in the common hippopotamus scapula. The hippopotamus humerus did not have the intermediate tubercle, only the greater and lesser tubercles, unlike the rhinoceros which also has the intermediate tubercle. The two megamammals studied had an ulna not incorporated to the radius and seven carpal bones distributed in two bone rows. The common hippopotamus had four digits and four metacarpal bones, while the white rhino had three digits, hence three metacarpal bones. Although with some species-specific differences, the bone anatomy found in the studied megaherbivores was similar to that described for domestic ungulates, such as horses and cattle. The fact that the bones studied belong to articulated skeletons of the collection of the Museum of Anatomy made it difficult to identify some anatomical structures. This study can help veterinarians in bone health care, animal welfare and comfort of such species present in Brazilian zoological parks.

Aunque los megaherbívoros no pertenecen a la fauna brasileña, se pueden encontrar en zoológicos nacionales, lo que hace importante conocer la anatomía del aparato locomotor para contribuir a la rutina clínica de los zoológicos y de los centros de rehabilitación veterinaria. Por tanto, el objetivo de este estudio fue describir las estructuras anatómicas de los huesos de los miembros torácicos en el hipopótamo común (Hippopotamus amphibius) y el rinoceronte blanco (Ceratotherium simum) y compararlas con las estructuras óseas descritas para otros ungulados. La escápula tenía una apariencia triangular en el hipopótamo común, mientras que en el rinoceronte blanco tenía una apariencia rectangular. El acromion se observó sólo en la escápula del hipopótamo común. El húmero del hipopótamo no tenía el tubérculo intermedio, sólo los tubérculos mayor y menor, a diferencia del rinoceronte que también tiene el tubérculo intermedio. Los dos ejemplares de megamamíferos estudiados tenían una ulna no incorporada al radio y siete huesos del carpo distribuidos en dos filas óseas. En el hipopótamo común se observaron cuatro dedos y cuatro huesos metacarpianos, mientras que en el rinoceronte blanco se encontraron tres dedos, por lo tanto, tres huesos metacarpianos.A pesar de algunas diferencias específicas de cada especie, la anatomía ósea encontrada en los megaherbívoros estudiados fue similar a la descrita para los ungulados domésticos, tal como los caballos y el ganado. El hecho de que los huesos estudiados pertenezcan a esqueletos articulados de la colección del Museo de Anatomía dificultó la identificación de algunas estructuras anatómicas. Este estudio puede ayudar a los veterinarios en el cuidado de la salud ósea, el bienestar animal y el confort de las especies presentes en los parques zoológicos brasileños.

Algoritmo diagnóstico y terapéutico de las lesiones esplácnicas provocadas durante la inserción de sondas pleurales / Diagnostic and Therapeutic Algorithm for Splanchnic Injuries Caused during Chest Tube Insertions

Introducción: La colocación de sondas pleurales es un procedimiento quirúrgico frecuente que puede tener graves complicaciones, las cuales dependen en la mayoría de los casos de la experiencia del operador, el tamaño del tubo y el uso de imágenes para guiar la inserción. Objetivo: Describir las principales lesiones esplácnicas provocadas durante la inserción de sondas pleurales y presentar algoritmos para el diagnóstico precoz y el tratamiento oportuno de estas iatrogenias. Métodos: Se realizó una revisión descriptiva narrativa durante el primer trimestre del año 2023. Se utilizaron las bases de datos electrónicas PubMed, LILACS, EBSCO y Cochrane. Se revisaron artículos publicados desde 1984 hasta el 2022. Se procuró que la mayoría de la información se enmarcara en un período no mayor de 10 años de antigüedad. Desarrollo: De las lesiones esplácnicas de la cavidad torácica, la de pulmón es la más frecuente y puede conducir a sangrado o fuga aérea persistente. Las lesiones vasculares son graves y pueden provocar la muerte si no se toman las medidas pertinentes. Se han descrito lesiones de órganos huecos de la cavidad abdominal que suelen ser parte de una hernia diafragmática. Dentro de las lesiones esplácnicas en el abdomen más frecuentes están la hepática y la esplénica. Conclusiones: Estas lesiones son prevenibles y se debe tener en cuenta su mecanismo de producción para evitarlas. Para este fin recomendamos una selección cuidadosa del sitio de inserción, realizar una confirmación adecuada de la posición de la sonda, manipularla cuidadosamente y monitorear constantemente al paciente(AU)

Introduction: Chest tube insertion is a frequent surgical procedure that can have serious complications, which depend mostly on the practitioner's experience, the tube's size and the use of imaging to guide the insertion. Objective: To describe the main splanchnic injuries caused during chest tube insertion, as well as to present algorithms for early diagnosis and timely treatment of these types of iatrogeny. Methods: A descriptive narrative review was performed during the first quarter of the year 2023. The electronic databases PubMed, LILACS, EBSCO and Cochrane were used. Articles published from 1984 to 2022 were reviewed. Most of the information was secured to be framed within a period of no more than 10 years. Development: Among the splanchnic injuries within the thoracic cavity, lung injury is the most frequent and may lead to bleeding or persistent air leak. Vascular injuries are severe and can lead to death if appropriate measures are not taken. Injuries to hollow organs of the abdominal cavity have been described to be usually part of a diaphragmatic hernia. Among the most frequent splanchnic lesions within the abdomen are the hepatic and splenic injuries. Conclusions: These lesions are preventable and their mechanism of production should be taken into account in order to avoid them. To achieve this, we recommend that the insertion site be carefully selected and that the tube's position be adequately confirmed, as well as the careful handling of the tube and the constant monitoring of the patient(AU)

Cirugía de Ross en Chile: Tasa libre de reoperación y supervivencia global en una cohorte de más de 10 años de seguimiento

Antecedentes: El autoinjerto de válvula pulmonar (VP) u operación de Ross (OpR) tiene excelentes resultados a largo plazo. Es superior a otros tipos de reemplazo valvular en jóvenes adultos, aunque no el estándar de primera línea. Un tiempo quirúrgico prolongado o alta morbimortalidad son importantes preocupaciones. Objetivos: Establecer la morbimortalidad asociada a la OpR por un período >10 años, considerando el tiempo quirúrgico, tasa de reoperación y supervivencia global (SG). Métodos: Cohorte prospectiva (1996-2012), en seguimiento hasta agosto-2023. La SG fue estimada desde la OpR hasta la última consulta o deceso. Mediante regresión de Cox (Hazard Ratio, HR) se estimaron factores asociados a la SG. Resultados: La serie consta de 161 pacientes: 118 de etiología congénita (73.3%), 17 infecciosa (10.6%), 26 reumática (16.1%). La lesión fue estenótica en 79 (49.1%), insuficiencia en 40 (24.8%), mixta en 42 (26.1%). La OpR fue urgente en 11 (6.8%). The median time of ECC and the operation was 149 y 232 minutos, respectivamente. Veintisiete pacientes requirieron reoperación (16.8%). Con una mediana de 19.7 años (17.2-22.2), 23 pacientes fallecieron (14.3%): 1/23 asociado a OpR, 17/23 por causa cardiovascular y 5/23 por causas no cardiovasculares. La lesión mixta se asoció a mayor mortalidad (HR 3.07; IC 95% 1.11-8.47; p=.029). Conclusiones: La OpR es un procedimiento con baja morbimortalidad. La lesión mixta es un factor de riesgo independiente de mayor mortalidad. Sin embargo, la mediana de tiempo de CEC y quirúrgico es prolongado frente a otras técnicas de reemplazo valvular.

Background: Pulmonary valve (PV) autograftor reoperation or Ross surgery (RS), presents excellent long-term results. It is superior to other types of PV replacement in young adults, although it is not the first-line gold standard. A longer operative time or high morbidity and mortality rates are important concerns. Aim: To establish the morbidity and mortality associated with RS for >10 years, considering operative time, reoperation rate and overall survival (OS). Methods: Prospective cohort (1996-2012), with a follow-up until August/2023. The OS was estimated from RS to the last consultation/death. Factors associated to OS were estimated using Cox regression (Hazard Ratio, HR) Results: 161 patients were included: the etiology was congenital (118, 73%), infectious (17, 10.6%), and rheumatic (26,16.1%). The lesion was stenotic in 79 (49.1%), heart failure in 40 (24.8%), mixed in 42 (26.1%). RS was urgent in 11 (6.8%). Extracorporeal circulation (ECC) and operative times were 149 and 232 minutes, respectively. Twenty-seven patients required reoperation (16.8%). With a median follow up of 19.7 years (17.2-22.2), 23 patients died (14.3%): 1/23 associated with RS, 17/23 due to cardiovascular causes, and 5/23 due to non-cardiovascular causes. Mixed injury was associated with higher mortality (HR 3.07; 95% CI 1.11-8.47; p=.029). Conclusions: RS is a procedure with low morbidity and mortality. Mixed injury is an independent risk factor for increased mortality. However, the median ECC and operative times were higher compared to other valvular replacement techniques.

ABSTRACT Background: Accelerated diagnostic protocols for chest pain, with the advancement of high-sensitivity troponin, make it possible to identify patients admitted to the emergency department with chest pain and low risk for a major adverse cardiovascular event, who could be discharged immediately, early and safely, saving time and resources. Objective: The aim of this study was to assess clinical trials using accelerated diagnostic protocols based on high-sensitivity troponin. Methods: A search of randomized clinical trials evaluating accelerated diagnostic protocols based on high-sensitivity troponin in emergency services was carried out in MEDLINE/Ovid, Cochrane and EMBASE database, using the assessment criteria of the Cochrane manual and the PRISMA strategy. Results: After screening 3509 studies, 5 clinical trials, including 1513 patients, were analyzed. Early discharges were identified in 409 (27%) of patients, in 91% of cases for ESC 0/3-h protocols, 72% for 0/1-h, 48% for EDACS, 40% for HEART, 19% and 32% for ADAPT and 8% and 18% for standard care protocols. The negative predictive value was high, in the 99.1-100% range. Mean length of hospital stay was lower for the 0/1-h and ESC 0/3-h protocols, with 4.6 and 5.6 hours, respectively. Conclusions: Accelerated diagnostic protocols in chest pain using high-sensitivity troponin allow a higher proportion of early discharges with a low rate of major cardiovascular events, with reduction in length of hospital stay and resources used.

Disección de aorta secundario a trauma, manejo clínico en Hospital General / Aortic dissection secondary to trauma, clinical management in General Hospital

INTRODUCCIÓN. La disección de aorta es una patología poco frecuente, cuando se presenta, lo hace de una manera catastrófica manifestada por dolor torácico o lumbar intenso acompañado de compromiso hemodinámico agudo, un diagnóstico y tratamiento temprano suelen ser cruciales para evitar la muerte del paciente, así mismo, una disección de aorta puede ser secundario a un trauma torácico por desaceleración y se presenta en 1,5% a 2%, lo que induce sobre todo a un desgarro localizado en la región del istmo aórtico. CASO CLÍNICO. Paciente masculino de 35 años, con antecedente de accidente en vehículo motorizado que provocó un traumatismo cráneo encefálico moderado, hematoma epidural parietal derecho, con resolución quirúrgica hace 18 meses, se descartó lesiones a nivel de tórax con radiografía de tórax normal, además se realizó ecografía FAST en ventana perihepática, suprapúbica, periesplénica y subxi-foidea sin encontrar alteración. Acudió al servicio de emergencia por un cuadro de hemiparesia derecha más disartria de 4 horas de evolución, se realiza tomografía de cráneo sin encontrarse lesión, catalogándose como evento cerebrovascular isquémico con recuperación neurológica. Durante su estancia hospitalaria presenta un cuadro de disnea de grandes esfuerzos y tras realizar exámenes complementarios de control se llega a una conclusión de una cardiomegalia, por lo que es referido a consulta de cardiología donde se realiza ecocardiograma, en la cual se observa disección de aorta ascendente más aneurisma por lo que se decide su ingreso y se instaura tratamiento mediante medidas de soporte, con derivación a hospital de especialidades para cirugía cardiotorácica. CONCLUSIONES. La disección de aorta secundario a un traumatis-mo es poco frecuente, sin embargo, el diagnostico siempre debe estar presente en caso de trauma por desaceleración, ya que es vital para la supervivencia del paciente y su manejo oportuno.

INTRODUCTION. Aortic dissection is an infrequent pathology; when it occurs, it does so in a catastrophic manner manifested by intense thoracic or lumbar pain accompanied by acute he-modynamic compromise. Early diagnosis and treatment are usually crucial to avoid the patient's death; likewise, aortic dissection can be secondary to thoracic trauma due to deceleration and occurs in 1.5% to 2%, which mainly induces a localized tear in the region of the aortic isthmus. CLINICAL CASE. 35-year-old male patient, with a history of motor vehicle accident that caused a moderate head injury, right parietal epidural hematoma, with surgical resolution 18 months ago, chest injuries were ruled out with normal chest X-ray, and FAST ultrasound was performed in perihepatic, suprapubic, perisplenic and subxiphoid window without finding any alteration. She went to the emergency department for a picture of right hemiparesis and dysarthria of 4 hours of evolution, a cranial tomography was performed without finding any lesion, being clas-sified as an ischemic cerebrovascular event with neurological recovery. During his hospital stay he presented with dyspnea of great effort and after performing complementary control tests, a cardiomegaly was found, so he is referred to a cardiology clinic where an echocardiogram is per-formed, which showed dissection of the ascending aorta plus aneurysm, admission is decided and treatment is instituted through supportive measures, with referral to a specialty hospital for cardiothoracic surgery. CONCLUSIONS. Aortic dissection secondary to trauma is rare, however, the diagnosis should always be present in case of trauma due to deceleration, as it is vital for the survival of the patient and its timely treatment.

Manejo conservador del neumotórax oculto en trauma

Introducción: El neumotórax oculto (NTXO) se encuentra hasta en el 15% de los traumatismos torácicos. Existen antecedentes del manejo conservador de esta patología (sólo observación), aunque su práctica continúa siendo discutida, especialmente, en traumatismos penetrantes. El objetivo de este trabajo es describir nuestra experiencia en el manejo conservador del NTXO. Materiales y Método: Estudio de cohorte retrospectivo realizado durante un período de 3 años en un Hospital de Trauma nivel I. Se incluyeron pacientes con traumatismo torácico (cerrado o penetrante) con NTXO. Se dividieron en dos grupos (conservados o drenados), realizándose una comparación de su evolución. Resultados: En 3 años fueron admitidos con traumatismo torácico 679 pacientes. De 93 pacientes con NTXO, 74 (80%) fueron conservados inicialmente y 19 (20%) tratados con drenaje pleural. Dos (3%) presentaron progresión del neumotórax en el seguimiento radiológico (conservación fallida). No se registraron complicaciones relacionadas con la ausencia de drenaje pleural. Las complicaciones y estancia hospitalaria fueron menores en el grupo de manejo conservador. Conclusión: Pacientes con NTXO por traumatismo de tórax (cerrado o penetrante), sin requerimiento de ventilación asistida y hemodinámicamente estables, pueden manejarse de manera conservadora con un monitoreo cercano durante 24 horas en forma segura, con menor tasa de complicaciones y de estancia hospitalaria.

Background: Occult pneumothorax (OPTX) is found in up to 15% of chest injuries. There is a history of conservative management of this pathology (only observation), although its practice continues to be discussed, especially in penetrating trauma. The objective of this paper is to describe our experience in the conservative management of OPTX. Materials and Method: Retrospective cohort study conducted over a 3-year period at a level I Trauma Center. Patients with thoracic trauma (blunt or penetrating) with OPTX were included. They were divided into two groups (preserved or drained) comparing their evolution. Results: Over a 3-year period 679 patients were admitted with chest trauma. From 93 patients with OPTX, 74 (80%) were initially preserved and 19 (20%) drained. Two patients (3%) presented pneumothorax progression in the follow-up imaging. There were no complications related to the absence of pleural drainage. Complications and hospital stay were lower in the conservative management group. Conclusion: Patients with OPTX due to chest trauma (blunt or penetrating), without requiring assisted ventilation and hemodynamically stable, can be safely conservative managed with close monitoring for 24 hours, with a lower rate of complications and hospital stay.
