Introduction: Adequate nursing intervention can improve post-operative outcomes, stress and knowledge; and reduce complications. Objective: Present a personalized nursing intervention in the pre-operative period of cardiovascular surgery at the Center for Medical and Surgical Research. Methods: A longitudinal and pre-experimental study was conducted, which included 88 people who attended the Cardiovascular Surgery Service of the Center for Medical and Surgical Research in a period of two years. The Trait-State Anxiety Inventory and Trait-State Depression Inventory tests were applied to measure anxiety and depression; as well as the ESCAPS test (Instrument for measuring the coping and adaptation process) and a semi-structured interview that explored knowledge. A personalized nursing intervention was performed. The initial and final results were compared, and expressed in absolute numbers, percentages and average. The Chi-square test was applied to the qualitative variables and the Student test for independent means to the quantitative variables, with a 95 percent confidence interval. Results: Men (57.9 percent) with a mean age of 57.73 ± 11.9 years predominated. After the intervention, anxiety was reduced by 36.6 percent (p < 0.001) and depression by 72.7 percent (p = 0). Knowledge increased (76.1 percent; p = 0.037) and coping and adaptive capacity (0.11 points). Only an association was found between anxiety and depression with complications (p = 0.008 and p < 0.001 respectively). Conclusions: Nursing intervention positively modified anxiety and depression by optimizing coping and adaptation capacity(AU)

Results of percutaneous closure with device in congenital heart disease of the atrial septal defect type / Resultados del cierre percutáneo con dispositivo en la cardiopatía congénita de tipo comunicación interauricular

Congenital Interatrial Septal Defects (TEA) are among the most common Congenital Heart Diseases in the population, where Atrial Septal Defect stands out, which is produced by a left-right short circuit that provides greater survival and less morbidity and mortality. The objective was to determine the results of Percutaneous Closure with a Device in Congenital Heart Disease of the Atrial Communication type at the Carlos Andrade Marín Specialty Hospital (Quito) in the Hemodynamics service from January 2009 to July 2019. It is a retrospective descriptive cross-sectional study . With a population of 122 cases from the AS400 registry. Thus, it was determined: there is a female predominance in a ratio of 2:1, the ranges for defect intervention were 5.5 mm to 35 mm, post-procedure pulmonary artery pressures (systolic 18-25 mmHg and diastolic 6-10 mmHg) in 95% of patients, ventricular overload in 76% in pre-procedure patients. Concluding that 96% of our population has a significant post-procedure improvement.

Los defectos del tabique interauricular congénitos (TEA) se encuentran entre las cardiopatías congénitas más comunes en la población donde resalta la comunicación interauricular que es producido por un cortocircuito izquierda derecha que brinda mayor sobrevida y menor morbimortalidad. El objetivo fue determinar los resultados del cierre percutáneo con dispositivo en la cardiopatía congénita de tipo comunicación interauricular en el hospital de especialidades Carlos Andrade Marín (Quito) en el servicio de hemodinamia en el período enero 2009 a julio 2019.

Concluyendo que el 96% de nuestra población tiene una mejoría significativa post-procedimiento.

Minimally Invasive Mini-orbitozygomatic Approach for Clipping an Anterior Communicating Artery Aneurysm: Virtual Reality Surgical Planning

Virtual reality (VR) has increasingly been implemented in neurosurgical practice. A patient with an unruptured anterior communicating artery (AcoA) aneurysm was referred to our institution. Imaging data from computed tomography angiography (CTA) was used to create a patient specific 3D model of vascular and skull base anatomy, and then processed to a VR compatible environment. Minimally invasive approaches (mini-pterional, supraorbital and mini-orbitozygomatic) were simulated and assessed for adequate vascular exposure in VR. Using an eyebrow approach, aminiorbitozygomatic approach was performed, with clip exclusion of the aneurysm from the circulation. The step-by-step process of VR planning is outlined, and the advantages and disadvantages for the neurosurgeon of this technology are reviewed.

Gasparyan method of total autologous reconstruction of the aortic valve

Abstract In this case report, I describe a new technique for total reconstruction of the aortic valve with autologous pericardium. The parameters of the cusps were calculated using very simple formulas after measurement of the aortic root intercommissural distances. Glutaraldehyde-treated pericardium was trimmed along the marked line, leaving 2 mm of tissue along the fibrous annulus attachment margin for the suture and small wings on both commissural margins to secure the commissural coaptation between right and noncoronary cusps. The annular margin of each pericardial cusp was sutured to the corresponding fibrous annulus with running 4/0 polypropylene suture. The commissures of pericardial patch and the commissural coaptation between right and noncoronary cusps were secured with mattress 4/0 polypropylene sutures. The coaptation of the three cusps was checked with negative pressure on the left ventricular vent before closure of the aortotomy. Intraoperative transesophageal echocardiogram revealed a peak pressure gradient of 10 mmHg and trivial aortic regurgitation.

Appropriate surgical repair of ventricular free wall rupture after infarction: a case report

Abstract Ventricular free wall rupture is a fatal mechanical complication of acute myocardial infarction. In some cases it can be represented as subacute clinic and may not cause death in a few minutes. Acute pseudo-aneurysms are extremely unstable and bound to fatal rupture. Herein we report a male patient who suffered dyspnea and mild chest pain, 4 weeks after acute ST-segment elevation myocardial infarction.

Milrinona inhalada en hipertensión pulmonar: A propósito de un caso / Case Report: Inhaled milrinone in pulmonary hypertension

INTRODUCCIÓN: Pulmonary hypertension (PH) is a disease that is characterized for an elevated pressure in the pulmonary artery and an increased pulmonary vascular resistance (PVR). Inhaled milrinone has demonstrated acting as a selective pulmonary vasodilator, being a useful tool for the treatment of patients with PH in the perioperative. MATERIALS AND METHODS: We report a successful case of inhaled milrinone in PH in cardiovascular surgery. The patient signed the informed consent for this report. DISCUSSION: Patients with PH has increased risk of perioperative complications (mortality as far as 37-90%) The management with intravenous vasodilators is frequently limited because of secondary effects of vasodilation and hypotension affecting the myocardial perfusion pressure. Milrinone is an inodilator that acts as an inhibitor of the phosphodiesterase III. Wang et al., and posterior studies have demonstrated that administered by inhalation it acts as a selective pulmonary vasodilator and inotrope, with a minor systemic effect. CONCLUSION: Inhaled milrinone have demonstrated to be a useful drug to lower PH, PVR and to enhance inotropism without deleterious systemic effects. Wide availability, lower costs and ease of administration make you think as it could be an ideal tool for perioperative management in patients with PH. There are still more studies to define it´s potentials.

INTRODUCCIÓN: La hipertensión pulmonar (HTP) es una enfermedad caracterizada por la elevación de las presiones de arteria pulmonar (PAP) y un aumento de la resistencia vascular pulmonar (RVP). La milrinona inhalada ha demostrado actuar como un vasodilatador pulmonar selectivo siendo una herramienta útil en el manejo de los pacientes con HTP en el perioperatorio. MATERIALES Y MÉTODOS: Reportamos un caso exitoso de milrinona inhalada en HTP en cirugía cardiovascular. La paciente firmó el consentimiento informado para este reporte. DISCUSIÓN: Pacientes con HTP tienen mayor riesgo de complicaciones perioperatorias (mortalidad hasta 37-90%). Su manejo con vasodilatadores intravenosos es frecuentemente limitado por sus efectos secundarios de vasodilatación e hipotensión, perjudicando la presión de perfusión miocárdica. La milrinona es un inodilatador que actúa como inhibidor de la fosfodiesterasa III. Wang et al., y estudios posteriores, han demostrado que administrada por vía inhalatoria actúa como un vasodilatador pulmonar selectivo e inótropo, con menor efecto sistémico. CONCLUSIÓN: La milrinona inhalada ha demostrado ser una herramienta útil para la disminución de la PAP, RVP y mejoría del inotropismo, sin efectos sistémicos deletéreos. Su amplia disponibilidad, menor costo y facilidad de administración, hacen pensar que podría ser una herramienta útil para el manejo perioperatorio de los pacientes con HTP. Hacen falta más trabajos para definir sus potencialidades.

Emergências cardiológicas: avaliação nutricional - parte I / Cardiological emergences: nutritional assessment - Part I

As emergências cardiológicas podem causar rápidas e profundas alterações na resposta metabólica e sistêmica. Essas alterações contribuem acentuadamente para a mobilização das reservas corporais que repercutirão no estado nutricional. A avaliação nutricional, ainda que não seja realizada na fase crítica da assistência interdisciplinar, deverá ser realizada o quanto antes, visando a adoção da alimentação adequada e reposição hídrica e de eletrólitos. O uso de ferramentas subjetivas capazes de estimar o risco nutricional global é de fácil aplicação devido a sua praticidade e rapidez. Entre essas destaca-se o Nutritional Risk Score ­ NRS 2002. Sempre que possível, a avaliação nutricional global deve ser complementada pela avaliação nutricional objetiva e pelo uso de marcadores nutricionais bioquímicos, os quais auxiliarão na avaliação mais precisa do estado nutricional do paciente crítico. Essas ferramentas devem ser utilizadas por nutricionistas treinados e os resultados devem ser discutidos pela equipe multidisciplinar de terapia nutricional que decidirá as estratégias mais adequadas para o início da terapia nutricional precoce nos quadros de emergências cardiológicas

Cardiac emergencies can cause rapid and profound changes in the metabolic and systemic response. These changes contribute significantly to the mobilization of body reserves, which will affect nutritional status. Nutritional evaluation, although not performed in the critical phase of interdisciplinary care, should be carried out as early as possible in order to ensure an adequate diet, and water and electrolyte replacement. The use of subjective tools capable of estimating the global nutritional risk is easy to apply due to its effective and rapid application. One such tool is the Nutritional Risk Score ­ NRS 2002. Whenever possible, the global nutritional assessment should be complemented with objective nutritional assessment and the use of biochemical nutritional markers, which will help obtain a more accurate evaluation of the nutritional status of the critically ill patient. These tools should be applied by trained nutritionists, and the results should be discussed by the multidisciplinary nutritional therapy team, which will decide on the most appropriate strategies for the initiation of early nutritional therapy in cardiac emergency situations

Retalho de omento maior no tratamento da mediastinite pós-operatória do lactente / Greater omentum flap in the treatment of infant postoperative mediastinitis

INTRODUÇÃO: A mediastinite pós-operatória é uma condição grave, com altas taxas de mortalidade. O retalho de omento maior é usado com êxito no tratamento de mediastinites pós-operatórias decorrentes de cirurgia cardíaca. O uso dessa abordagem não foi relatado em lactentes, provavelmente porque nessa idade o omento maior é membranáceo, pouco volumoso e possui tecido adiposo escasso. MÉTODOS: Entre julho de 2010 e agosto de 2014, foram tratados quatro lactentes com mediastinite pós-operatória decorrentes de cirurgia cardíaca, realizada por esternotomia. O tratamento cirúrgico consistiu em remoção dos fios de aço da osteossíntese esternal, desbridamento e lavagem do mediastino, seguidos da transposição de todo o omento maior para a cavidade mediastinal. O tratamento cirúrgico foi feito em um só tempo. Não foi feita nova síntese do esterno com fios de aço. RESULTADOS: Os quatro pacientes sobreviveram ao tratamento e obtiveram alta da unidade de tratamento intensivo sem infecção. CONCLUSÕES: Embora membranáceo e apresentando pequeno volume, o retalho de omento maior se mostrou um excelente método de abordagem da mediastinite pós-operatória do lactente.

INTRODUCTION: Postoperative mediastinitis is a serious condition that presents high mortality rates. The greater omentum flap has been used with good results in postoperative mediastinitis after cardiac surgery. The use of this approach has not been reported in infants probably because at this age, the greater omentum is membranous, not bulky, and has little amount of fatty tissue. METHOD: Between July 2010 and August 2014, four infants who presented with mediastinitis after a cardiac surgery via sternotomy were treated. The surgical treatment consisted of steel wire removal, debridement, and wound washing, followed by transposition of the entire greater omentum to the mediastinal cavity. Surgical treatment was performed in a single step. No rewiring of the sternum was performed. RESULTS: All four patients survived the treatment and were discharged from the intensive care unit without infection. CONCLUSIONS: Although membranous and not bulky, the use of a greater omentum flap proved to be an excellent approach in infant postoperative mediastinitis.

Benefício do uso de recuperadores de hemácias em cirurgias cardiovasculares / Benefit from using recycling red blood cells in cardiovascular surgery

Objetivo: Avaliar se o uso de recuperadores de hemácias está indicado nos pacientes submetidos à cirurgia cardiovascular com o uso de circulação extracorpórea. Métodos: Foram estudados 77 pacientes submetidos a cirurgias cardíacas com uso de recuperadores de hemácias e circulação extracorpórea de novembro de 2010 a junho de 2012. A amostra foi subdividida em três grupos, conforme o tempo de circulação extracorpórea. No grupo A ,o tempo de circulação extracorpórea foi menor que 45, no grupo B, de 45 a 90 e, no grupo C, maior que 90 minutos. Analisou-se o volume recuperado e infundido de hemácias, a hemoglobina de pré, trans e pós-operatório, número de unidades de concentrado de hemácias transfundidas, volume globular e hemoglobina do sangue infundido.

Em relação às transfusões de concentrado de hemácias, no grupo A foram transfundidas 1,00±2,00 concentrado de hemácias, no B 1,27±1,85 concentrado de hemácias e no C 2,56±2,01 concentrado de hemácias. O sangue infundido tinha um volume globular de 50,97±12,06% e hemoglobina de 19,57±8,35 g/dl. Conclusão: O recuperadores de hemácias podem ser usados em pacientes submetidos à cirurgia cardiovascular com circulação extracorpórea, mas somente em cirurgias com tempo de circulação extracorpórea acima de 45 minutos o reaproveitamento de sangue ...

Objective: To show if blood salvage is indicated in all patients submitted to cardiovascular surgery with cardiopulmonary bypass. Methods: We studied 77 consecutive patients submitted to cardiac surgery with use of blood salvage and cardiopulmonary bypass from November 2010 to June 2012. The sample was divided in three groups, depending on the time of cardiopulmonary bypass. In group A, the time of cardiopulmonary bypass was smaller than 45, in group B from 45 to 90 and in group C greater than 90 minutes. We analyzed the volume of red cells recovered and infused, the pre, intra and post-operative hemoglobin, the number of packed red cells units which were transfused and hematocrit and hemoglobin blood infused. Results: The average group age was 60.44±12.09 years old, of whom 71.43% were males. The group A was formed by 5.19% of the patients, B by 81.82% and C by 12.99%. The volume of erythrocytes recovered and infused was respectively 1,360.50±511.37 ml and 339.75±87.71 ml in group A, 1,436.63±516.06 ml and 518.83±183.0 ml in B and 2,137.00±925.04 ml and 526.20±227.15 ml in C. About packed red cells transfusions, in group A 1,00±2,00 packed red cells were transfused, in B 1.27±1.85 packed red cells and in C 2.56±2.01 packed red cells. The infused blood had a hematocrit of 50.97±12.06% and hemoglobin of 19.57±8.35 g/dl. Conclusion: That blood salvage can be used in patients submitted to cardiovascular surgery with cardiopulmonary bypass. However, it is only cost-effective in surgeries in which the time of cardiopulmonary bypass is greater than 45 minutes. .

Fechamento percutâneo versus cirúrgico da comunicação interatrial em crianças e adolescente / Percutaneous versus surgical closure of atrial septal defects in children and adolescents

FUNDAMENTO: Há uma paucidade de dados comparando o método percutâneo e o cirúrgico para tratamento da comunicação interatrial tipo ostium secundum. OBJETIVOS: Análise de segurança e eficácia comparando ambos os métodos tratamento em um hospital excelência com vínculo o Ministério de Saúde. MÉTODOS: Estudo observacional, prospectivo, não randomizado de duas coortes de crianças e adolescentes < 14 anos tratadas por meio do cateterismo intervencionista (grupo A) ou da cirurgia cardíaca convencional (grupo B). A coleta dos dados foi prospectiva no grupo A e retrospectiva no B. RESULTADOS: De abr/2009 a out/2011 foram alocados 75 pts no grupo A e entre jan/2006 e jan/2011foram tratados 105 pts no grupo B. A idade e o peso dos pacientes foram maiores no grupo B e o diâmetro da comunicação interatrial do tipo ostium secundum foi semelhante entre os grupos. Sucesso técnico foi observado em todos os procedimentos e não houve óbitos. Complicações (a maioria menores) foram encontradas em 68% no grupo B e em 4% do grupo A (p < 0,001). As taxas de fluxo residual não significativo ou de oclusão total do defeito foram semelhantes nos dois grupos. A mediana de internação foi de 1,2 dias após o procedimento percutâneo e 8,4 dias após a correção cirúrgica (p < 0,001). CONCLUSÃO: Ambos os tratamentos são seguros e eficazes com ótimos desfechos, porém o tratamento percutâneo apresenta menor morbidade e tempo de internação. Tais observações embasam a visão que essa forma de tratamento deve ser, hoje em dia, o método de escolha para pacientes selecionados com CIA do tipo ostium secundum.

BACKGROUND: There is a scarcity of data comparing percutaneous and surgical closure of the secundum atrial septal defect (ASD). OBJECTIVES: Assessment of safety and efficacy of both methods of treatment in a referral center affiliated with the Ministry of Health. METHODS: Observational, prospective, non-randomized study of two cohorts of children and adolescents younger than 14 years, treated by catheterization or surgery. Data was collected prospectively in the percutaneous group (A) and retrospectively in the surgical group (B). RESULTS: A total of 75 patients (pts) were enrolled in group A from April 2009 to October 2011 and 105 pts were treated in group B from January 2006 to January 2011. Age was older and weight was higher in group B and the ASD diameter was similar in both groups. Technical success was achieved in all procedures and there were no deaths. Complications (most minor) occurred in 68% of group B and 4% of A (p < 0.001). Rates of total occlusion or non-significant residual shunts were similar in both groups. Median hospitalization time was 1.2 days in group A and 8.4 days in group B (p < 0.001). CONCLUSION: Both treatment modalities are safe and effective, showing excellent outcomes. However, the percutaneous treatment has lower morbidity and shorter in-hospital stay length. These observations support the concept that percutaneous treatment of atrial septal defects should be regarded as the method of choice to manage selected patients with this condition.

The following variables were evaluated: pain intensity, analgesic consumption, lumber of analgesic requests and side effects. Results: There has been no pain in 86 per cent of patients. Predominant side-effects were nausea and vomiting with significant decrease in morphine consumption and request. Conclusion: Continuous infusion plus bolus is safe and effective to control pain.

Resultados quirúrgicos y factores de riesgo relacionados a mortalidad operatoria en la corrección quirúrgica de 276 pacientes consecutivos con tetralogía de Fallot / Surgical outcomes and risk factors of operative mortality in 276 consecutives patients with tetralogy of Fallot

La tetralogía de Fallot es una de las cardiopatías congénitas cianógenas más frecuentes. A pesar de ello no existen en Venezuela reportes actualizados de los resultados de su corrección quirúrgica. Describir los resultados obtenidos en la reparación quirúrgica de pacientes con tetralogía de Fallot y evaluar los factores de riesgo de mortalidad operatoria relacionados así como describir la sobrevida actuarial y la libertad de reoperación del tracto de salida del ventrículo derecho. Se incluyeron en forma restrospectiva a todos aquellos pacientes intervenidos de corrección total de tetralogía de Fallot entre octubre 2006 a mayo 2010. Se evaluó el tiempo de by-pass cardiopulmonar, tiempo de pinzamiento aórtico, edad, peso, talla, relación de presiones entre el ventrículo derecho e izquierdo después de la corrección. Adicionalmente se trazaron las curvas actuariales para sobrevida y libertad de reoperación para el tracto de salida derecho. Solo el tiempo de circulación extracorporea mayor a 100 minutos estuvo relacionado a mortalidad operatoria. La mortalidad operatoria global fue de 5,8%. La sobrevida actuarial a los 4 años fue de 92,5%, y la libertad de reoperación por obstrucción del tracto de salida derecho fue de 98,4%. Los resultados obtenidos son similares a los observados en la literatura mundial en relación con la mortalidad operatoria y libertad de reoperación del tracto de salida derecho. Los tiempos de circulación extracorporea mayores a 100 minutos podrían estar relacionados a una mayor dificultad técnica de la corrección y esto a su vez estar relacionado a mortalidad.

Tetralogy of Fallot is one of the most common cyanotic congenital heart defects. However, in Venezuela there are no current reports of results of its surgical correction. To describe the results of surgical repair of Tetralogy of Fallot patients and evaluate the risk factors related to operative mortality and to describe the actuarial survival curves and freedom from reoperation for the right ventricule outflow tract obstruction. We included retrospectively all patients undergoing total correction of tetralogy of Fallot from October 2006 to May 2010. We evaluated time of cardiopulmonary bypass, aortic cross-clamp time, age, weight, height, and pressure ratio between right and left ventricle after correction. Additionally actuarial curves were plotted for survival and freedom from reoperation for right outflow tract obstruction. Cardiopulmonary by-pass times longer than 100 minutes was related to operative mortality. The overall operative mortality was 5.8%. The actuarial survival at 4 years was 92.5%, and freedom from reoperation for right outflow tract obstruction was 98.4%. These results are similar to those observed in the literature regarding the operative mortality and freedom from reoperation for right outflow tract obstruction. Cardiopulmonary by-pass times longer than 100 minutes could be related to increased technical difficulties during correction and this in turn be related to mortality.

Perspective on coronary interventions & cardiac surgeries in India.

Cardiovascular disease has become the leading cause of morbidity and mortality in India during the last 3 decades. The genetic predisposition and acquisition of traditional risk factors at a rapid rate as a result of urbanization seems to be the major cause. While efforts are being made to contain this epidemic by educating public and applying preventive measures, the ever increasing burden of patients with symptomatic and life threatening manifestations of the disease is posing a major challenge. This requires a concerted effort to develop modern facilities to treat these patients. The healthcare facilities to manage these high risk patients by contemporary methods like percutaneous coronary revascularization and surgical methods have shown a very promising trend during the last decade. The facilities of modern diagnostic methods and new proven techniques to offer symptomatic relief and improve their prognosis are available in most parts of the country. The lack of social security and health insurance for the large majority of the population, however, is a serious limitation. Unregulated availability of some of the newer devices for these techniques had become a very concerning issue. However, in the last few years serious efforts have been made to streamline these procedures. Indigenous research and scientific data acquisition in relation to the modern technology for achieving coronary revascularization has also started on a promising note.

Avaliação do desempenho funcional em pacientes submetidos à cirurgia cardiaca / Evaluation of functional performance in patients undergoing cardiac surgery

Fundamentos: A cirurgia cardíaca é uma forma de tratamento que, apesar de trazer melhora para o paciente, acarreta alterações no organismo. Objetivo: Avaliar a influência da dor, na primeira cirurgia e na reoperação com uso de circulação extracorpórea (CEC), na medida de independência funcional (MIF). Métodos: Foram estudados 22 pacientes cardiopatas, internados na Fundação de Beneficência Hospital de Cirurgia, submetidos à cirurgia cardíaca eletiva por toracotomia médio-esternal (TME) com uso de circulação extracorpórea (CEC) no período de março a abril 2010. Utilizou-se o questionário da medida de independência funcional (MIF) e a escala de dor pela escala visual analógica (EVA) no pré-operatório, 2º/3º dias pós-operatórios (DPO) e 5º/6º DPO. Resultado: Houve uma redução da dor do 2º/3º DPO para o 5º/6º DPO; uma perda de desempenho funcional do pré-operatório para o 2º/3ºDPO e um ganho deste do 2º/3º DPO para 5º/6º DPO com p<0,001. Não se obteve uma correlação significante entre a dor e o quantitativo cirúrgico com o desempenho funcional, apenas deste com o tempo de CEC, que se mostrou inversamente proporcional. Conclusão: A dor, na primeira cirurgia e na reoperação, não influenciou a medida de independência funcional, sendo apenas influenciada pelo tempo de CEC.

Background: Cardiac surgery is a form of treatment that causes changes in the body, although offering improvement for the patient. Objective: To evaluate the influence of pain during the initial surgery and reoperation with the use ofcardiopulmonary bypass (CPB) on the functional independence measure (FIM).Methods: This study focused on 22 cardiac patients in the Fundação de Beneficência Hospital de Cirurgia(FBHC) hospitalized for elective heart surgery through mid-sternal thoracotomy (MST) with cardiopulmonary bypass (CPB) between March and April 2010, using thefunctional independence measure (FIM) questionnaire and the Visual Analog Scale (VAS) for pain in the preoperative, 2/3 and 5/6 PODs. Results: Pain reduction was noted between 2/3 and 5/6 PODs; a loss of functional performance between the preoperativeperiod and the 2/3 PODs; and a gain between the 2/3 and 5/6 PODs with p<0.001. No statistically significant correlation was found between pain and the amount of surgery with functional performance, but only between the latter and the duration of the CPB, whichwas inversely proportional. Conclusion: Pain caused by the first surgery andreoperation did not affect the functional independence measure, which was influenced only by the CPB.

Profilaxis de la enfermedad tromboembólica en cirugía / Prevention of thromboembolism in surgery

La enfermedad tromboembólica es un término que incluye a la trombosis venosa profunda y el tromboembolismo pulmonar, complicación más temida. Dentro de los factores de riesgo para desarrollar estas patologías destacan los períodos de inmovilización, pacientes sometidos a grandes cirugías y pacientes cursando una patología oncológica. Estas condiciones son parte del perfil común del paciente hospitalizado en los servicios quirúrgicos, situación que es similar en nuestro subdepartamento. En la siguiente revisión presentamos la norma creada por el Equipo de Vascular del Subdepartamento de Cirugía del Hospital Base Valdivia abordando la estratificación del paciente quirúrgico hospitalizado, las alternativas no farmacológicas, farmacológicas, destacando el uso de heparinas de bajo peso molecular, los nuevos anticoagulantes orales, y cuál es la recomendación actual en cada situación.
