Introduction: During the preoperative period of cardiovascular surgery, people frequently present high levels of depression, associated with little favorable surgical outcomes and, therefore, with the need for a nursing intervention to reduce such levels. Objective: To evaluate the effectiveness of a nursing intervention to reduce depression in preoperative cardiovascular patients. Methods: A preexperimental study with pretest and protest was carried out in a population of 88 people in the cardiovascular surgery service at Centro de Investigaciones Médico-Quirúrgicas, in Havana, Cuba, from March 2019 to June 2020. Depression was measured using the State/Trait Depression Inventory test. A nursing intervention was performed, based on the Adaptation Model of Sister Callista Roy, the Nursing Care Process, as well as the NANDA, NOC and NIC taxonomies, in order to reduce depression in preoperative cardiovascular patients. The results were compared and expressed as percentages, mean and absolute numbers. The chi-square and Fisher's exact probability tests were used. The association of variables was obtained with the nonparametric Wilcoxon test, with the dissociation rule if p ≤ 0.05, H O is rejected. Results: The male sex accounted for 57.92 percent of the cases and the mean age was 57-years. After the intervention, depression was reduced by 27.27 percent (p= 0.000). Conclusions: The implementation of a nursing intervention to reduce depression in preoperative cardiovascular patients, based on the Adaptation Model of Sister Callista Roy, the Nursing Care Process, as well as NANDA, NOC and NIC taxonomies, showed effectiveness, since it was possible to modify depression in a positive and significant way, while optimizing postoperative outcomes(AU)

Does type 2 diabetes mellitus increase postoperative complications in patients submitted to cardiovascular surgeries?

Abstract Objective: To compare the incidence of postoperative complications (PC) between diabetic and nondiabetic patients undergoing cardiovascular surgeries (CS). Methods: This is a retrospective cross-sectional study, based on the analysis of 288 medical records. Patients aged ≥ 18 years, admitted to the intensive care unit (ICU) between January 2012 and January 2013, and undergoing coronary artery bypass grafting (CABG) or vascular surgeries were included. The population was divided into those with and without type 2 diabetes mellitus (T2DM), and then it was evaluated the incidence of PC between the groups. Results: The sample included 288 patients, most of them being elderly (67 [60-75] years old) male (64%) subjects. Regarding to surgical procedures, 60.4% of them were undergoing vascular surgeries and 39.6% were in the postoperative period of CABG. The incidence of T2DM in this population was 40% (115), just behind hypertension, with 72% (208). Other risk factors were also observed, such as smoking in 95 (33%) patients, dyslipidemias in 54 (19%) patients, and previous myocardial infarction in 55 (19%) patients. No significant difference in relation to PC (bleeding, atrial fibrillation, cardiorespiratory arrest, and respiratory complications) between the groups was observed (P>0.05). Conclusion: T2DM has a high incidence rate in the population of critically ill patients submitted to CS, especially in the elderly. However, in this small retrospectively analyzed study, there was no significant increase in PC related to diabetes for patients undergoing CS.

Entre los parámetros de evolución posquirúrgica, se observó un incremento en la duración de la internación, requerimiento de inotrópicos, días de asistencia respiratoria mecánica, sangrado y complicaciones neurológicas.Conclusión. La incidencia de LRA en este estudio fue del 35 %. Se pudieron definir factores de riesgo modificables y no modificables asociados, y se detectó una mayor incidencia de complicaciones en aquellos pacientes que desarrollaron LRA

Introduction. Acute kidney injury (AKI) has been described as a common complication of cardiac surgery in pediatric patients, whose impact on morbidity and mortality has been documented. Its incidence has been estimated to be approximately 40 % in this patient group. The objective of this study was to estimate the incidence of AKI in patients who underwent cardiovascular surgery and to define associated risk factors and the impact of AKI on the parameters of the post-operative course.Population and methods. This was a retrospective, observational study of pediatric patients who underwent cardiovascular surgery between January 2015 and December 2017 at Hospital Británico de Buenos Aires. The incidence of AKI was defined as per the Kidney Disease: Improving Global Outcomes criteria, based on pre- and post-operative blood creatinine levels and urine output.Results. A total of 125 patients were included. Of them, 35 % developed AKI. The analysis of risk factors showed a statistically significant difference for the administration of vancomycin and thiazide diuretics, red blood cell transfusion requirement, extracorporeal circulation pump time, clamp time, maximal intraoperative lactate level, minimum temperature, and delayed chest closure. In relation to the parameters of the post-operative course, we observed a longer hospital stay, higher inotropic requirement, more days of mechanical ventilation, bleeding, and neurological complications.Conclusion. In this study, the incidence of AKI was 35 %. Modifiable and non-modifiable associated risk factors were defined and a greater rate of complications was observed in patients who developed AKI.

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

Survival and risk factors among dialytic acute kidney injury patients after cardiovascular surgery

Abstract Objective: Acute kidney injury (AKI) is a frequent postoperative complication after cardiovascular surgery. It has been described as a predictor of decreased survival rates, but how dialysis decreases survival when initiated on the postoperative period has yet to be determined. To analyze the survival of patients who presented postoperative AKI requiring dialysis up to 30 days after cardiovascular surgery and its risk factors is the aim of this study. Methods: Of the 5,189 cardiovascular surgeries performed in a 4-year period, 157 patients developed AKI requiring dialysis in the postoperative period. The Kaplan-Meier survival curve and log-rank test were used in the statistical analysis to compare the curves of categorical variables. P-value< 0.05 was considered significant. Results: Patient average survival was 546 days and mortality was 70.7%. The need for dialysis on the postoperative period decreased late survival. Risk factors for decreased survival included age (P<0.001) and postoperative complications (P<0.0003). Conclusion: The average survival was approximately one year among dialytic patients. Age and postoperative complications were risk factors that determined decreased survival.

Evolução pós-operatória mediata e tardia de pacientes submetidos a cirurgias cardíacas eletivas / Postoperative medium and long-term evolution of patients who underwent elective cardiac surgery

Introdução. O estudo procurou investigar a evolução pós-operatória (PO) mediata e tardia de pacientes que participaram de um estudo anterior, sendo submetidos à primeira cirurgia de revascularização do miocárdio (CRM), correção de valvopatias e cirurgias combinadas, entre agosto/2013 e fevereiro/2015. Objetivo. Identificar as principais complicações e a ocorrência de óbito no PO mediato e investigar a evolução tardia desses pacientes, dentro de dois anos, quanto aos locais de retorno, necessidade de novas internações e de procedimentos relacionados ao aparelho circulatório, presença de infecção de sítio cirúrgico (ISC) e desfecho ao término deste período. Método. Estudo observacional, tipo coorte retrospectiva. Coletouse os dados mediante consulta aos prontuários dos pacientes e ao sistema de intranet do hospital, de março/2016 a outubro/2017. No PO mediato investigou-se a presença de complicações por sistema e o desfecho da internação; no PO tardio investigou-se o local dos retornos ambulatoriais; reinternações e suas causas; novos procedimentos/condutas relacionados ao aparelho circulatório; presença de ISC e desfecho clínico após dois anos. Realizamos uma análise descritiva das variáveis do estudo. Resultados. A amostra foi composta por 118 pacientes, 59 (50%) submetidos à CRM, 48 (40,6%) às cirurgias para correção de valvopatias e 11 (9,4%) às cirurgias combinadas. A hiperglicemia foi a complicação mais frequente entre pacientes que realizaram a CRM (64,4%) e entre aqueles submetidos às cirurgias combinadas (45,5%). No grupo de pacientes que realizaram cirurgias para correção de valvopatias, a complicação mais frequente foi o distúrbio de coagulação (20,8%). Todos os pacientes da amostra tiveram alta hospitalar. Quanto ao seguimento PO inicial, todos os pacientes, independentemente da cirurgia realizada, tiveram pelo menos um retorno no hospital do estudo. Ao longo de dois anos após a alta, 25,4% dos pacientes submetidos à CRM foram reinternados, assim como 33,3% dos submetidos às cirurgias para correção de valvopatias e 18,2% dos submetidos às cirurgias combinadas. Dois pacientes do grupo de CRM foram submetidos à intervenção coronária percutânea (ICP) e apenas um do grupo de válvula foi submetido a uma nova cirurgia cardíaca no período do estudo. Quanto à ISC, no grupo de CRM, cinco pacientes apresentaram infecção na safenectomia, um evoluiu com endocardite e um com mediastinite; no grupo de valva, apenas um evoluiu com endocardite, daqueles submetidos às cirurgias combinadas, um apresentou infecção da ferida esternal e um mediastinite. A maioria dos pacientes encontrava-se vivo após dois anos da alta hospitalar (CRM = 96,6%; cirurgia de valva = 83,3% e cirurgia combinada = 90,9%). Conclusão. A frequência de complicações dos pacientes no PO mediato foi baixa, e todos tiveram alta hospitalar. Quanto à evolução PO tardia, a maioria dos pacientes permanecia em acompanhamento ambulatorial no hospital do estudo após dois anos da alta hospitalar. Entre os pacientes estudados, apenas um do grupo de cirurgias corretivas de valvopatias foi submetido a nova cirurgia cardíaca, e dois do grupo de CRM à ICP. Quanto à ISC, poucos a desenvolveram, a maioria dos quais pertencia ao grupo de CRM. A maioria deles, independentemente da cirurgia realizada, encontrava-se vivo após dois anos da alta hospitalar

Introduction. This study aimed at investigating the medium and long-term postoperative (PO) evolution of patients who participated in a previous study, who were submitted to the first myocardium revascularization surgery (MRS), valvopathy correction and to combined surgeries, from August/2013 to February/2015. Objective. Identifying the main complications and cases of death among patients in the medium-term PO and investigate the late evolution of these patients, within two years, their return to the hospital, the need for other hospitalizations, the need for new procedures regarding their circulatory system, the presence of surgical site infections (SSI) and their outcome in this period. Method. Observational and retrospective cohort study. Data was collected from the records of patients and the intranet system of the hospital, from March/2016 to October/2017. In the medium-term PO, the complications in each system were investigated as was the outcome of the hospitalization; in the long-term PO, the site of outpatient returns; rehospitalizations and their motives; new procedures/conducts related to the circulatory system; the presence of SSI and the clinical outcome after two years. A descriptive analysis of the study variables was made. Results. The sample of the study included 118 patients, 59 (50%) had undergone MRS, 48 (40.6%) valvopathy correction surgeries and 11 (9.4%) combined surgeries. Hyperglycemia was the most common medium-term PO complication among patients who underwent the combined surgery (45.5%), while those who underwent valvopathy correction surgeries most commonly presented coagulation disorder (20.8%). All patients in the sample were discharged. Regarding the initial PO monitoring, all patients came back to the hospital at least once. Regarding the rehospitalizations in the first two years after the discharge from the first heart surgery, 25.4% of patients who underwent MRS were re-hospitalized, as were 33.3% of those who underwent valvopathy correction surgeries and 18.2% of those who underwent combined surgeries. Two patients from the MRS group were submitted to percutaneous coronary interventions (PCI) and only one in the group of corrective valvopathy was submitted to another surgery in the period of the study. Regarding the presence of SSI, in the SMR group, five patients had infections after saphenectomies, one had endocarditis and one, mediastinitis; considering valvopathy correction patients, one presented with endocarditis, while one of those who underwent combined surgeries had sternum injuries and another, mediastinitis. Most patients were alive two years after discharge (SMR=96.6%; valvopathy correction=83.3% and combined surgery=90.9%). Conclusion. The frequency of complications among patients in the medium-term PO was low, and all of them were discharged from the hospital. Regarding long-term PO evolution, most patients were undergoing outpatient monitoring in the hospital were the study was conducted two years after hospital discharge. Among all patients in the study, only one, in the group of valvopathy correction, underwent new cardiac surgeries, and two of the SMR group underwent PCI. Few patients presented SSI, and most were in the MRS group. Most patients were alive after two years

Pre-Frailty Increases the Risk of Adverse Events in Older Patients Undergoing Cardiovascular Surgery / Pré-Fragilidade Aumenta o Risco de Eventos Adversos em Idosos Submetidos à Cirurgia Cardiovascular

Abstract Background: Frailty is identified as a major predictor of adverse outcomes in older surgical patients. However, the outcomes in pre-frail patients after cardiovascular surgery remain unknown. Objective: To investigate the main outcomes (length of stay, mechanical ventilation time, stroke and in-hospital death) in pre-frail patients in comparison with no-frail patients after cardiovascular surgery. Methods: 221 patients over 65 years old, with established diagnosis of myocardial infarction or valve disease were enrolled. Patients were evaluated by Clinical Frailty Score (CFS) before surgery and allocated into 2 groups: no-frailty (CFS 1~3) vs. pre-frailty (CFS 4) and followed up for main outcomes. For all analysis, the statistical significance was set at 5% (p < 0.05). Results: No differences were found in anthropometric and demographic data between groups (p > 0.05). Pre-frail patients showed a longer mechanical ventilation time (193 ± 37 vs. 29 ± 7 hours; p<0.05) than no-frail patients; similar results were observed for length of stay at the intensive care unit (5 ± 1 vs. 3 ± 1 days; p < 0.05) and total time of hospitalization (12 ± 5 vs. 9 ± 3 days; p < 0.05). In addition, the pre-frail group had a higher number of adverse events (stroke 8.3% vs. 3.9%; in-hospital death 21.5% vs. 7.8%; p < 0.05) with an increased risk for development stroke (OR: 2.139, 95% CI: 0.622-7.351, p = 0.001; HR: 2.763, 95%CI: 1.206-6.331, p = 0.0001) and in-hospital death (OR: 1.809, 95% CI: 1.286-2.546, p = 0.001; HR: 1.830, 95% CI: 1.476-2.269, p = 0.0001). Moreover, higher number of pre-frail patients required homecare services than no-frail patients (46.5% vs. 0%; p < 0.05). Conclusion: Patients with pre-frailty showed longer mechanical ventilation time and hospital stay with an increased risk for cardiovascular events compared with no-frail patients.

Resumo Fundamentos: A fragilidade é reconhecida como um importante preditor de eventos adversos em pacientes cirúrgicos idosos. Entretanto, os desfechos em pacientes com pré-fragilidade após a cirurgia cardiovascular ainda permanecem desconhecidos. Objetivos: Investigar os principais desfechos (tempo de internação, tempo de ventilação mecânica, incidência de acidente vascular cerebral e óbito intra-hospitalar) após cirurgia cardiovascular em pacientes com pré-fragilidade em comparação a pacientes sem fragilidade. Métodos: 221 pacientes acima de 65 anos de idade, com diagnóstico de infarto do miocárdio ou doença valvar foram recrutados no estudo. Os pacientes foram avaliados pela escala de fragilidade clínica (CFS, Clinical Frailty Score) antes da cirurgia e separados em 2 grupos: sem-fragilidade (CFS 1~3) vs. pré-fragilidade (CFS 4). Para todas as análises, foi considerada diferença significativa quando p < 0,05. Resultados: Não foram observadas diferenças nos dados antropométricos e demográficos entre os grupos. Os pacientes com pré-fragilidade apresentaram maior tempo de ventilação mecânica em comparação a pacientes sem fragilidade (193 ± 37 vs. 29 ± 7 horas; p < 0,05); resultados similares foram observados para tempo de permanência na unidade de terapia intensiva (5 ± 1 vs. 3 ± 1 days; p < 0,05) e tempo total de internação hospitalar (12 ± 5 vs. 9 ± 3 dias; p < 0,05). Além disso, os pacientes com pré-fragilidade apresentaram maior número de eventos adversos (acidente vascular cerebral-AVC 8,3% vs. 3,9%; óbito intra-hospitalar 21,5% vs. 7,8%; p<0,05) com risco aumentado para AVC (OR: 2,139, IC 95%: 0,622-7,351, p = 0,001; HR: 2,763, IC 95%: 1,206-6,331, p = 0,0001) e morte intra-hospitalar (OR: 1,809, IC 95%: 1,286-2,546, p = 0,001; HR: 1,830, IC 95%: 1,476-2,269, p = 0,0001). Além disso, um maior número de pacientes com pré-fragilidade necessitaram de fisioterapia domiciliar que pacientes sem fragilidade (46,5% vs. 0%; p< 0,05). Conclusão: Pacientes com pré-fragilidade apresentaram maior tempo de ventilação mecânica e maior tempo de internação hospitalar, com maior risco de desenvolverem eventos cardiovasculares adversos em comparação a pacientes sem fragilidade.

Causas de readmissão hospitalar após cirurgia cardíaca / Causes of hospital readmission after heart surgery

Objetivou-se identificar o perfil e as causas de readmissão de pacientes submetidos à cirurgia cardíaca. Estudo retrospectivo, descritivo, realizado por meio de revisão de prontuários de pacientes submetidos à cirurgia de revascularização do miocárdio ou implante de prótese valvar com readmissão posterior. A amostra foi constituída por 62 pacientes. A taxa de readmissão foi de 5,9%. A infecção do sítio cirúrgico foi a principal causa de readmissão em 87,5% dos pacientes submetidos à revascularização do miocárdio e em 12,5% dos implantes de prótese valvar (p˂0,001) e esteve associada às variáveis obesidade (p=0,05) e dislipidemia (p=0,007). A identificação dos pacientes em risco para o desenvolvimento de infecção do sítio cirúrgico pode minimizar as taxas de readmissão e diminuir os custos associados ao cuidado, e, merece um planejamento diferenciado de ações multiprofissionais

The objective was to identify readmission's profile and causes of heart surgery patients. A retrospective, descriptive study, through the revision of records from patients submitted to myocardial revascularization surgery or valvar prosthesis implantation with posterior readmission. Sixty-two patients composed the sample. The readmission rate was 5.9%. Surgical site infection was the main cause for readmission in 87.5% of patients submitted to myocardial revascularization surgery and in 12.5% of valvar implantation (p<0.001) and, it was associated with obesity (p=0.05) and dyslipidemia (p=0.007). To identify patients at risk of surgical site infection can minimize readmission rates and decrease care costs and, it deserves a special planning of multi-professional actions.

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.

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.

Influence of fresh frozen plasma as a trigger factor for kidney dysfunction in cardiovascular surgery / Plasma fresco congelado como fator de risco para a disfunção renal no pós-operatório de cirurgia cardiovascular

OBJECTIVE: Kidney dysfunction is a major complication in the postoperative cardiac surgery setting. Operative risk factors for its development are cardiopulmonary bypass, anemia, antifibrinolytic drugs and blood transfusion. The objective of this study was to identify the risk factors for developing kidney dysfunction in patients undergoing cardiac surgery. METHODS: Ninety-seven patients were studied and 84 were analyzed. The sample was stratified into two groups. A serum creatinine higher than 30% compared to the preoperative period was considered for the kidney dysfunction group (n=9; 10.71%). There also was a control group when the increase in serum creatinine remained lower than 30% (n=75; 89.28%). RESULTS: It was observed that intraoperative transfusion of fresh frozen plasma in the control group was 2.05 ± 0.78 units and 3.80 ± 2.16 units in the kidney dysfunction group with P= 0.032. CONCLUSION: It was possible to associate that fresh frozen plasma transfusion is a risk factor for postoperative kidney dysfunction after cardiovascular surgery.

OBJETIVO: A disfunção renal é uma complicação importante no cenário de pós-operatório de cirurgia cardiovascular. Como fatores de risco conhecidos no intraoperatório para o seu desenvolvimento destacam-se a circulação extracorpórea, a hemodiluição, drogas antifibrinolíticos e a transfusão sanguínea. O objetivo deste estudo é identificar os fatores de risco na transfusão de sangue e derivados para o desenvolvimento de disfunção renal em pacientes submetidos à cirurgia cardiovascular. MÉTODOS: Noventa e sete pacientes foram estudados e 84 foram analisados. A amostra foi estratificada em dois grupos, sendo que o incremento de 30% na creatinina sérica no pós-operatório foi considerado para o grupo com disfunção renal (n = 9; 10,71%). O grupo não disfunção renal foi caracterizado pela creatinina sérica, que permaneceu inferior a aumento de 30% no pós-operatório (n = 75; 89,28%). RESULTADOS: Foi observado que a transfusão de plasma fresco congelado no grupo não disfunção renal foi de 2,05 ± 0,78 unidades e 3,80 ± 2,16 unidades no grupo disfunção renal com P= 0,032. CONCLUSÃO: Foi possível associar, nesta série de pacientes, que a transfusão de plasma fresco congelado foi um fator de risco para disfunção renal pós-operatório de cirurgia cardiovascular.

Mediastinite no pós-operatório de cirurgia cardiovascular: análise de 1038 cirurgias consecutivas / Mediastinitis in cardiovascular surgery postoperation: analysis of 1038 consecutive surgeries

OBJETIVO: Relatar a incidência de mediastinite no pós-operatório de cirurgia cardiovascular. MÉTODOS: Foram analisados os prontuários de 1038 pacientes submetidos à cirurgia cardiovascular entre maio/ 2007 e junho/2009. Todas as operações foram realizadas na Divisão de Cirurgia Cardiovascular do Pronto Socorro Cardiológico de Pernambuco - PROCAPE. RESULTADOS: A mediastinite ocorreu, em média, 13 dias após a cirurgia, num total de 25 (2,4 por cento) casos, com taxa de letalidade 32,0 por cento (n=8). Vários fatores de risco foram identificados: 56 por cento diabéticos, 56 por cento tabagistas, 20 por cento obesos, 16 por cento portadores de doença pulmonar obstrutiva crônica e 8 por cento com insuficiência renal crônica. A maioria (n=21; 84,0 por cento) dos casos foi observada em pacientes submetidos à revascularização do miocárdio, sendo esta associada a maior risco de desenvolvimento da infecção (IC 3.44-8.30, P=0,0001). Observou-se alto índice de complicações: insuficiência respiratória (44 por cento), acidente vascular cerebral (16 por cento), choque cardiogênico (12 por cento), insuficiência renal aguda (28 por cento), infecção pulmonar (36 por cento), falência de múltiplos órgãos (16 por cento) e deiscência de esterno (48 por cento). A cultura do exsudato foi positiva em 84 por cento dos casos, sendo o Staphylococcus aureus o patógeno mais observado (28,8 por cento). CONCLUSÕES: A mediastinite continua como complicação cirúrgica bastante grave e de difícil manuseio no pós-operatório de cirurgia cardiovascular. A doença permanece como de baixa incidência, entretanto, ainda com alta letalidade. A cirurgia de revascularização está associada a maior risco de desenvolvimento da infecção.

OBJECTIVE: To report the incidence of mediastinitis in cardiovascular surgery postoperation. METHODS: The records of all 1038 patients who underwent cardiovascular surgical procedures between May/2007 and June/2009 were reviewed. All operations were performed in Division of Cardiovascular Surgery of Pronto Socorro Cardiológico de Pernambuco - PROCAPE. RESULTS: The complication occurred within, on average, 13 days after operation, in total of 25 (2.4 percent), eight (32 percent) deaths occurred. Several risk factors mediastinitis were identified: 56 percent diabetes, 56 percent smokers, 20 percent obeses, 16 percent with chronic obstructive pulmonary disease and 8 percent of chronic renal failure. Mediastinitis were reported in 21 (84 percent) cases of patients submitted to coronary artery bypass grafting, being associated to major risk of infection development (IC 3.448.30, P=0.0001). High rates of complications were observed: respiratory insufficiency (44 percent), stroke (16 percent), cardiogenic shock (12 percent), acute renal failure (28 percent), pulmonary infection (36 percent), multiple organs failure (16 percent) and esternal deiscence (48 percent). Bacterial cultures of exudates were positive in 84 percent of patients; Staphylococcus aureus was the most responsible pathogen (28.8 percent). CONCLUSION: Mediastinitis stays a serious surgical complication and difficult management in cardiovascular surgery postoperation. The disease stays with low incidence, but still with high lethality. Coronary bypass was associated to major risk of infection development.

Late aortic dilatation and regurgitation after Ross operation

The Ross operation, a procedure of replacement of the diseased aortic valve with an autologous pulmonary valve, has many advantages such as no need for anticoagulation therapy and similar valve function and growth potential as native valves. However secondary aortic disease has emerged as a significant complication and indication for reoperation. We report a 48-year-old woman who had Ross operation in 1997 for a damaged bicuspid aortic valve and severe aortic regurgitation due to subacute bacterial endocarditis complicated by aortic root abscess. In 2009, 12 years later, progressive severe aortic regurgitation with incomplete coaptation and mild dilatation of the aortic root was shown on echocardiography and contrasted CT, while the pulmonary homograft retained normal function. She subsequently underwent aortic valve replacement. Histopathological examination of the explanted neo-aortic valve and neo-arterial wall revealed pannus formation at the nodulus Arantii area of the three valve cusps, ventricularis, and arterialis. The amount of elastic fibres in the neo-aorta media was less than usual for an aorta of this patient's age but was similar to a pulmonary artery. The pathological findings were not different from other studies of specimens removed between 7 to 12 years after Ross operation. However, the pathophysiology and long-term implications of these findings remain debatable. Considering the anatomical and physiological changes induced by the procedure, separate mechanisms for aortic dilatation and regurgitation are worthy of consideration.

Bandagem da artéria pulmonar: uma cirurgia simples? Uma análise crítica em um centro terciário / Pulmonary artery banding: a simple procedure? A critical analysis at a tertiary center

OBJETIVO: A bandagem da artéria pulmonar (BAP) é um procedimento tecnicamente simples, mas envolto em várias peculiaridades que o fazem apresentar elevadas taxas de morbidade e mortalidade. O objetivo deste estudo é analisar a experiência de um hospital de referência na bandagem da artéria pulmonar, avaliando e correlacionando diversas variáveis relacionadas ao procedimento. MÉTODOS: Entre janeiro de 2000 e dezembro de 2008, 61 pacientes submetidos a BAP por cardiopatia congênita de hiperfluxo no Hospital do Coração de Messejana-Fortaleza/CE foram avaliados quanto a mortalidade, complicações, permanência em ventilação mecânica (VM) e terapia intensiva (UTI), uso de drogas vasoativas, dificuldade de ajustes transoperatórios e reoperações para reajuste. Análise estatística foi realizada para comparações entre subgrupos. RESULTADOS: Em 46,8 por cento dos pacientes, não se conseguiu o ajuste pressórico pretendido e 6,5 por cento precisaram ser reoperados para reajustes. O tempo médio UTI e VM foi 14,16 ± 10,92 dias e 14,1 ± 49,6 dias, respectivamente. Em 82,6 por cento dos pacientes foram administradas drogas vasoativas por 10,30 ± 12,79 dias. Complicações graves incidiram em 49,15 por cento dos pacientes, com predominância da insuficiência cardíaca (44 por cento). A taxa de mortalidade foi de 8,2 por cento, não influenciada por peso, procedimentos associados ou cardiopatia univentricular ou biventricular. CONCLUSÃO: Neste estudo, a BAP foi realizada com taxas de mortalidade aceitáveis, compatíveis com a literatura mundial. No entanto, os ajustes transoperatórios são de difícil análise, tornando o procedimento complexo e justificando elevados índices de complicações, resultando em longa permanência em UTI. Nenhuma variável isolada representou significante fator de risco, dentre as quais, fisiologia uni ou biventricular

OBJECTIVE: Although pulmonary artery banding (PAB) seems to be a technically simple procedure it presents several peculiarities and is related to a significant morbidity and mortality. The aim of this study is to analyze the experience of a tertiary hospital on the PAB by assessing and correlating many aspects related to the procedure. METHODS: Between January 2000 and December 2008, 61 patients undergone PAB due to congenital heart disease with increased pulmonary blood flow at Messejana Heart Hospital were assessed as for mortality, complications, stay in mechanical ventilation and need for intensive care unit (ICU), use of vasoactive drugs, difficulties in the adjustment on the banding and reoperations. Some statistical analyzes were performed to compare the subgroups. RESULTS: In 46.8 percent of the patients the intended pressoric adjustment was not achieved and in 6.5 percent it was necessary another surgery to readjust the banding. The mean time of mechanical ventilation was 14.1±49.6 days and ICU 14.16±10.92 days. In 82.6 percent of the patients vasoactives drugs were administrated for 10.3±12.79 days. Severe complications were noted in 49.15 percent of patients and cardiac insufficiency was the most common one with an incidence of 44 percent. The mortality rate was 8.2 percent and it was not influenced by weight or associated procedures with the PAB neither if univentricular or biventricular heart disease. CONCLUSION: The PAB can be performed with acceptable mortality rates compatible with the ones of the world literature. Nevertheless, the adjustment of the banding is difficult to be assessed during the surgery by making the procedure complex and justifying the high incidence of complications and long stay in ICU. It wasn't found any specific risk factor significant to mortality neither uni- or biventricular heart disease

Emprego do suporte cardiopulmonar com bomba centrífuga e oxigenador de membrana em cirurgia cardiovascular pediátrica / Use of centrifugal pump and extracorporeal membrane oxygenation as cardiopulmonary support in pediatric cardiovascular surgery

FUNDAMENTO: O suporte cardiopulmonar com oxigenador de membrana é um método de ressuscitação de distúrbios hemodinâmicos, pulmonares ou ambos, consagrado em centros internacionais. OBJETIVOS: Descrever diversos aspectos relacionados ao suporte cardiopulmonar com oxigenador de membrana em um serviço de cirurgia cardiovascular nacional e determinar seus resultados imediatos e tardios. MÉTODOS: Entre outubro de 2005 e janeiro de 2007, 10 pacientes foram submetidos a suporte circulatório e/ou respiratório em candidatos ou submetidos a cirurgia cardiovascular pediátrica, com idade mediana de 58,5 dias (40 por cento de neonatos) e peso mediano de 3,9 kg. O suporte foi mantido com a intenção de recuperação e desmame, de acordo com critérios clínicos e ecocardiográficos diários. O suporte foi descontinuado nos pacientes sem indicação de transplante, com incapacidade de recuperação e com sobrevida limitada, de acordo com julgamento multidisciplinar. RESULTADOS: O suporte circulatório foi utilizado no pós-operatório de operações corretivas ou paliativas em 80 por cento e no pré-operatório no restante. Instabilidade hemodinâmica grave irresponsiva (40 por cento), falência miocárdica na saída de circulação extracorpórea (20 por cento) e parada cardíaca no pós-operatório (20 por cento) foram as indicações mais freqüentes. O tempo médio de permanência em suporte circulatório foi de 58 ± 37 horas. O suporte foi retirado com sucesso em 50 por cento e 30 por cento obtiveram alta hospitalar. A sobrevida atuarial foi de 40 por cento, 30 por cento e 20 por cento aos 30 dias, 3 meses e 24 meses, respectivamente. CONCLUSÃO: O suporte cardiopulmonar com oxigenador de membrana foi um método eficaz e útil na ressuscitação de distúrbios cardiovasculares e pulmonares graves no perioperatório de cirurgia cardiovascular pediátrica.

BACKGROUND: Extracorporeal membrane oxygenation is a well-documented resuscitation method in patients with severe hemodynamic and/or respiratory impairment. OBJECTIVE: To describe several aspects related to the use of extracorporeal membrane oxygenation in a pediatric heart center and determine its immediate and late outcomes. METHODS: Between October 2005 and January 2007, 10 patients who were submitted to pediatric cardiac surgery underwent extracorporeal membrane oxygenation implant. Median age was 58.5 days (40 percent neonates) and median body weight was 3.9 kg. Circulatory assistance was initiated aiming at the recovery and the weaning protocols followed daily clinical and echocardiographic criteria. Support was discontinued when transplant was contraindicated, when the patient was unable to recover or when survival was considered to be limited by a multidisciplinary team. RESULTS: Extracorporeal membrane oxygenation was employed after corrective or palliative heart surgery in 80 percent and preoperatively in the remaining ones. It was most often indicated for irresponsive hemodynamic instability (40 percent), post-cardiotomy shock (20 percent) and post-cardiac arrest (20 percent). The mean duration on support was 58 ± 37 hours. Weaning was successfully in 50 percent of the cases and 30 percent were discharged home. Actuarial survival was 40 percent, 30 percent and 20 percent at 30 days, 3 months and 24 months, respectively. CONCLUSION: Extracorporeal membrane oxygenation is an effective and useful tool for the resuscitation of patients presenting severe hemodynamic and/or respiratory failure in the perioperative period of pediatric cardiovascular surgery.
