RESUMO

La creación de una fístula arteriovenosa (FAV) determina un incremento del gasto cardíaco, cuya magnitud está relacionada con el tamaño del cortocircuito. En el escenario adecuado esta puede conducir al desarrollo de insuficiencia cardíaca (IC) con alto gasto cardiaco. Se presenta el caso de un paciente que desarrolla IC luego de la confección de una FAV para hemodiálisis crónica y sus implicancias clínicas posteriores. Se revisan aspectos diagnósticos y terapéuticos referidos a la IC de alto gasto.

The creation of an arteriovenous fistula (AVF) determines an increase in cardiac output, the magnitude of which is related to the size of the shunt. In the right scenario, this can lead to the development of heart failure (HF) with high cardiac output. The case of a patient who develops HF after creating an AVF for chronic hemodialysis and its subsequent clinical implications is presented. Diagnostic and therapeutic aspects related to high-output HF are reviewed.

RESUMO

O objetivo do presente estudo foi levantar, na literatura atual, estudos relevantes que identifiquem as possíveis respostas hemodinâmicas encontradas em indivíduos hipertensos praticantes do Método Pilates. A revisão sistemática conduzida conforme as recomendações PRISMA em cinco bases de dados eletrônicas (PEDro, PubMed, SciELO, LILACS e Cochrane), disponibilizado desde o início das bases até Março de 2019, com descritores MESH conforme segue: [("Adult" OR "Young adult" OR "Middle Aged" OR "Aged" OR "Elderly") AND ("exercise movement techniques" OR "Pilates-Based Exercises" OR "Pilates Training") AND ("Hemodynamics" OR "Heart Rate" OR "Cardiac Chronotropy" OR "Heart Rate Control" OR "hypertension" OR "Blood Pressure" OR "High Blood Pressure" OR "Systolic Pressure" OR "Diastolic Pressure" OR "High Blood Pressure" OR "Pulse Rate Determination")], posteriormente ajustado para as demais bases. Busca complementar manual nas referências dos artigos incluídos na pesquisa e Google Scholar. Foram incluídos estudos de intervenção, com idade maior ou igual a 18 anos; diagnóstico de hipertensão arterial sistêmica (HAS); submetidos a exercícios de pilates solo e/ou pilates aparelhos como método de intervenção e incluído a descrição de análise das variáveis hemodinâmicas de pressão arterial (PA), frequência cardíaca (FC) e duplo produto (DP). Após processo de seleção foi selecionado apenas um único estudo que tenha contemplado todos os critérios de elegibilidade, totalizando 44 indivíduos do sexo feminino, com média de idade de 50,5 anos (±6,3 anos), hipertensas com utilização de medicação, onde 22 foram submetidas ao pilates solo e 22 permaneceram no grupo controle. O estudo apresentou resultados positivos na frequência cardíaca (FC), pressão arterial (PA) e no duplo-produto (DP) em comparação ao grupo controle. Apesar do número limitado de manuscritos encontrados nesta revisão, os resultados das variáveis hemodinâmicas nos levam a considerar plausível a utilização do Mat pilates em pacientes com HAS. Entretanto, novos estudos devem ser realizados para a confirmação dos achados...(AU)

The aim this study was to raise in the current literature relevant studies that identify the possible hemodynamic responses found in hypertensive individuals practicing the Pilates Method. The systematic review conducted according to PRISMA recommendations in five electronic databases (PEDro, PubMed, SciELO, LILACS and Cochrane), available from the beginning of the databases until March 2019, with MESH descriptors as follows: [("Adult "OR" Young adult "OR" Middle Aged "OR" Aged "OR" Elderly ") AND (" Exercise Movement Techniques "OR" Pilates-Based Exercises "OR" Pilates Training ") AND (" Hemodynamics "OR" Heart Rate " OR "Cardiac Chronotropy" OR "Heart Rate Control" OR "Hypertension" OR "Blood Pressure" OR "High Blood Pressure" OR "Systolic Pressure" OR "Diastolic Pressure" OR "High Blood Pressure" OR "Pulse Rate Determination")] , later adjusted to the other bases. Manual complementary search in the references of the articles included in the search and Google Scholar. Intervention studies, 18 years of age or older were included; diagnosis of systemic arterial hypertension (SAH); submitted to solo pilates exercises and / or pilates apparatus as intervention method and included the description of analysis of hemodynamic variables of blood pressure (BP), heart rate (HR) and double product (SD). After the selection process, only one study was selected that met all the eligibility criteria, totaling 44 female individuals, with a mean age of 50.5 years (± 6.3 years), hypertensive with medication use, where 22 were submitted to solo pilates and 22 remained in the control group. The study showed positive results in heart rate (HR), blood pressure (BP) and double product (SD) compared to the control group. Despite the limited number of manuscripts found in this review, the results of hemodynamic variables lead us to consider the use of Mat pilates in patients with hypertension to be plausible. However, further studies should be performed to confirm the findings...(AU)

RESUMO

Introducción: la anomalía de Ebstein es una rara malformación congénita cardiaca, definida por un desplazamiento apical de las valvas septal y posterior de la válvula tricúspide hacia el interior del ventrículo derecho, en vez de hacerlo a nivel del anillo auriculoventricular, lo cual conlleva un aumento del volumen de la aurícula derecha (megaurícula) a expensas de una reducción del tamaño del ventrículo del mismo lado (auriculización del ventrículo). Causa una significante regurgitación tricuspídea y reducción de la capacidad funcional del ventrículo, dilatación atrioventricular derecha, con arritmias auriculares y ventriculares, las que tienden a hacerse resistentes en ocasiones, o de difícil tratamiento. El desplazamiento del orificio valvular tricuspídeo produce una división del ventrículo derecho en una porción integrada al atrio derecho, lo que constituye la porción atrializada del ventrículo derecho, en tanto la porción apicotrabecular y de salida constituye su parte funcional. Objetivo: presentar la evolución clínico-anestesiológica de una paciente con anomalía de Ebstein. Caso clínico: paciente de 69 años de edad programada para cirugía electiva en dos ocasiones por diferentes enfermedades oncológicas, portadora de anomalía de Ebstein. Antecedentes de tromboembolismo pulmonar, tres cirugías cardiacas, diabetes mellitus e hipertensión arterial, enfermedad arterial aterosclerótica estable e infarto cerebral media derecha embólico. Se evitaron aquellas condiciones que aumenten el trabajo cardiaco y el consumo de oxígeno. Conclusiones: el desafío que representa para el anestesiólogo, aquellos pacientes que sufren anomalía de Ebstein puede variar de paciente a paciente, en dependencia del estado físico, el tipo de enfermedad y las técnicas de monitorización(AU)

Introduction: Ebstein's anomaly is a rare congenital cardiac malformation, defined by an apical displacement of the septal and posterior leaflets of the tricuspid valve into the right ventricle, instead of at the level of the atrioventricular ring, which leads to an increase of the volume of the right atrium (mega atrium) at the expense of a size reduction for the ventricle on the same side (auriculization of the ventricle). It causes a significant tricuspid regurgitation and reduction of the functional capacity of the ventricle, right atrioventricular dilation, with atrial and ventricular arrhythmias, which tend to become resistant at times, or difficult to treat. The displacement of the tricuspid valve orifice produces a division of the right ventricle in a portion integrated to the right atrium, which constitutes the atrialized portion of the right ventricle, while the apico-trabecular and exit portion constitutes its functional part. Objective: To present the clinical-anesthesiological evolution of a patient with Ebstein's anomaly. Clinical case: A 69-year-old patient, with Ebstein's anomaly, who was scheduled for elective surgery on two occasions for different oncological diseases. History of pulmonary thromboembolism, three cardiac surgeries, diabetes mellitus and arterial hypertension, stable atherosclerotic arterial disease, and right middle cerebral infarction. Conditions that increase cardiac work and oxygen consumption were avoided. Conclusions: The challenge patients suffering from Ebstein's anomaly represent for the anesthesiologist can vary from patient to patient, depending on the physical state, the type of disease, and the monitoring techniques(AU)

RESUMO

A 33 years old woman was admitted to the hospital after four days with cough, dyspnea, orthopnea and hemoptysis. Blood pressure was 170/90 mmHg, pulse was 112 and temperature was normal. She had cyanosis and a left ventricular gallop, without heart murmurs. A chest radiograph revealed pulmonary edema and echocardiogram showed a global left ventricular systolic disfunction. Oxygen and furosemide were started, but cardiopulmonary collapse ensued. The patient was supported with mechanical ventilation and treated with inotropic drugs. A right sided cardiac catheterization showed pulmonary wedge pressure of 18 mmHg and a cardiac index of 3 l/min/m2. The levels of creatinine and urea nitrogen were elevated and a urine protein was 97 mg/dl. Coagulation tests were normal except by a positive lupic anticoagulant. Markers of connective tissue diseases or vasculitis were negatives. The clinical evolution suggested that a catastrophic antiphospholipid syndrome was ongoing. Intravenous corticoids, gammaglobulin and cyclophosphamide were administered with transient improvement. On her fourth day of treatment, the patient presented sudden pulmonary bleeding and embolism. A plasmapheresis was performed with improvement of renal, cardiac and pulmonary function. After this episode, the patient has been treated with prednisone and oral anticoagulants treatment for the last two years, without further clinical events.

RESUMO

Beriberi (BB), thiamine deficiency, has been described in the Asian literature in the 17th century and is characterized by peripheral neuropathy and muscle weakness, also called "dry" beriberi (BB) to differentiate it from "wet" BB, with essentially cardiovascular manifestations. Wet can be either "classic" wet BB in which signs and symptoms of right-sided heart failure with normal or high cardiac output are the presenting features or the "shoshin" BB variant with severe biventricular failure and metabolic acidosis, which must be treated early to prevent the rapid development of low cardiac output failure and sudden death. In this case, we report a 58 year old alcoholic woman who developed dyspnea, oliguria, edema, cardiac failure with high output, metabolic acidosis, renal tubular dysfunction and serum lactate level of 5.6 mEq/L. Neurological examination revealed peripheral neuropathy in the lower legs and cognitive alteration. She was treated with a loading dose of 100 mg of intravenous thyamine and responded with a marked increase in urine output, correction of acidosis, reduction in pulmonary-capillary wedge pressure and a change of the hemodynamic pattern. We conclude that shoshin-BB is uncommonly encountered but not widely recognized. In lactic acidosis and/or hyperdynamic circulation without any other apparent etiology in patients with possible vitamin B1 deficiency, the diagnosis of BB must be considered and thiamine should be administered.
