RESUMO
ABSTRACT Global Cardiac Surgery is an innovative initiative with a focus on improving health outcomes and achieving healthcare equity for individuals worldwide affected by cardiac surgical conditions or in need of cardiac surgical care. Considering the existing disparities in access to cardiac surgery and the substantial burden of cardiac conditions amenable to surgical procedures in Brazil, it is imperative to support and scale Global Cardiac Surgery initiatives and leave no Brazilian patient behind. Here, we advocate for national initiatives within this field and highlight opportunities and challenges to support their development.
RESUMO
ABSTRACT Introduction: Cardiac surgery is a frequent surgical procedure and may present a high risk of complications. Among the prophylactic strategies studied to decrease the rates of negative outcomes, respiratory care seems to reduce pulmonary complications. Incentive spirometry (IS) is a low-cost, respiratory exercise technique, used for the prevention and treatment of postoperative pulmonary complications (PPC). The aim of this review was to evaluate whether IS is superior to respiratory care, mobilization exercises, and noninvasive ventilation on PPC, and clinical outcomes. Methods: Systematic review. Medical Literature Analysis and Retrieval System Online (or MEDLINE®), Embase®, Cochrane Central Register of Controlled Trials (or CENTRAL), Physiotherapy Evidence Database (or PEDro), Cumulative Index of Nursing and Allied Health (or CINAHL®), Latin American and Caribbean Health Sciences Literature (or LILACS), Scientific Electronic Library Online (or SciELO), Allied, Scopus®, and OpenGrey databases, clinical trial registration sites, conferences, congresses, and symposiums were searched. Results: Twenty-one randomized trials and one quasi-randomized trial (1,677 participants) were included. For partial pressure of oxygen (PaO2), IS was inferior to respiratory care (mean difference [MD] -4.48; 95% confidence interval [CI] -8.32 to -0.63). Flow-oriented IS was inferior to respiratory care on PaO2 (MD -4.53; 95% CI -8.88 to -0.18). However, compared to respiratory care, flow-oriented IS was superior on recovery vital capacity. Conclusions: This meta-analysis revealed that IS was not superior to standard respiratory care for PPCs and clinical outcomes, therefore its use should not be widely recommended until further studies with high quality be performed to ensure this clinical guidance.
RESUMO
ABSTRACT Introduction: It is not yet clear whether cardiac surgery by mini-incision (minimally invasive cardiac surgery [MICS]) is overall less painful than the conventional approach by full sternotomy (FS). A meta-analysis is necessary to investigate polled results on this topic. Methods: PubMed®/MEDLINE, Cochrane CENTRAL, Latin American and Caribbean Health Sciences Literature (or LILACS), and Scientific Electronic Library Online (or SciELO) were searched for all clinical trials, reported until 2022, comparing FS with MICS in coronary artery bypass grafting (CABG), mitral valve surgery (MVS), and aortic valve replacement (AVR), and postoperative pain outcome was analyzed. Main summary measures were the method of standardized mean differences (SMD) with a 95% confidence interval (CI) and P-values (considered statistically significant when < 0.05). Results: In AVR, the general estimate of postoperative pain effect favored MICS (SMD 0.87 [95% CI 0.04 to 1.71], P=0.04). However, in the sensitivity analysis, there was no difference between the groups (SMD 0.70 [95% CI -0.69 to 2.09], P=0.32). For MVS, it was not possible to perform a meta-analysis with the included studies, because they had different methodologies. In CABG, the general estimate of the effect of postoperative pain did not favor any of the approaches (SMD -0.40 [95% CI -1.07 to 0.26], P=0.23), which was confirmed by sensitivity analysis (SMD -0.02 [95% CI -0.71 to 0.67], P=0.95). Conclusion: MICS was not globally less painful than the FS approach. It seems that postoperative pain is more related to the degree of tissue retraction than to the size of the incision.
RESUMO
Resumo Fundamento A infecção do sítio cirúrgico (ISC) é uma importante complicação no pós-operatório de cirurgia cardíaca pediátrica associada ao aumento da morbimortalidade. Objetivos Identificar fatores de risco para a ISC após cirurgias cardíacas para correção de malformações congênitas. Métodos Este estudo caso-controle incluiu 189 pacientes com um ano completo e 19 anos e 11 meses, submetidos à cirurgia cardíaca em hospital universitário terciário de cardiologia de janeiro de 2011 a dezembro de 2018. Foi realizado registro e análise de dados pré, intra e pós-operatórios. Para cada caso foram selecionados dois controles, conforme o diagnóstico da cardiopatia e cirurgia realizada em um intervalo de até 30 dias para minimizar diferenças pré e/ou intraoperatórias. Para a análise dos fatores de risco foi utilizado o modelo de regressão binária logística. Significância estatística definida como valor de p<0,05. Resultados O estudo incluiu 66 casos e 123 controles. A incidência de ISC variou de 2% a 3,8%. Fatores de risco identificados: faixa etária de lactentes (OR 3,19, IC 95% 1,26 - 8,66, p=0,014), síndrome genética (OR 6,20, IC 95% 1,70 - 21,65, p=0,004), RACHS-1 categorias 3 e 4 (OR 8,40, IC 95% 3,30 - 21,34, p<0,001), o valor da proteína C reativa (PCR) de 48 horas pós-operatórias foi demonstrado como fator protetor para esta infecção (OR 0,85, IC 95% 0,73 - 0,98, p=0,023). Conclusão Os fatores de risco identificados não são variáveis modificáveis. Vigilância e medidas preventivas contínuas são fundamentais para reduzir a infecção. O papel do PCR elevado no pós-operatório foi fator protetor e precisa ser melhor estudado.
Abstract Background Surgical site infection is an important complication after pediatric cardiac surgery, associated with increased morbidity and mortality. Objectives We sought to identify risk factors for surgical site infection after pediatric cardiac surgeries. Methods A case-control study included patients aged between 1 year and 19 years and 11 months of age, submitted to cardiac surgery performed at a tertiary cardiac center from January 1 st , 2011, through December 31, 2018. Charts were reviewed for pre-, intra, and postoperative variables. We identified two randomly selected control patients with the same pathophysiological diagnosis and underwent surgery within thirty days of each index case. Univariate and multivariate logistic regression analyses were performed to identify risk factors. Statistical significance was defined as p<0.05. Results Sixty-six cases and 123 controls were included. Surgical site infection incidence ranged from 2% to 3.8%. The following risk factors were identified: Infant age (OR 3.19, 95% CI 1.26 to 8.66, p=0.014), presence of genetic syndrome (OR 6.20, CI 95% 1.70 to 21.65, p=0.004), categories 3 and 4 of RACHS-1 (OR 8.40, CI 95% 3.30 to 21.34, p<0.001), 48 h C-reactive protein level range was detected as a protective factor for this infection (OR 0.85, 95% CI 0.73 to 0.98, p=0.023). Conclusions The risk factors defined in this study could not be modified. Therefore, additional surveillance and new preventive strategies need to be implemented to reduce the incidence of surgical site infection. The increased CRP in the postoperative period was a protective factor that needs further understanding.
RESUMO
ABSTRACT Objective: To evaluate the occurrence of adverse events in the postoperative period of cardiac surgery in a pediatric intensive care unit and to find any patient characteristics that can predict such events. Methods: This was a historical cohort study of patients recovering in the pediatric intensive care unit for the first 7 days after cardiac surgery between April and December 2019, by reviewing the medical records. The following were reviewed: demographic, clinical, and laboratory characteristics; patient severity scores; and selected adverse events, grouped into device-related, surgical, and nonsurgical. Results: A total of 238 medical records were included. At least one adverse event occurred in 110 postoperative patients (46.2%). The total number of adverse events was 193 (81%). Vascular catheters were the most common cause, followed by cardiac arrest, bleeding, and surgical reexploration. In the univariate analysis, the vasoactive-inotropic score (VIS), Risk Adjustment in Congenital Heart Surgery (RACHS-1) score, age, Pediatric Index of Mortality (PIM-2), cardiopulmonary bypass and aortic clamping duration were significantly associated with adverse events. In the multivariate analysis, VIS ≥ 20 (OR 2.90; p = 0.004) and RACHS-1 ≥ 3 (OR 2.11; p = 0.019) were significant predictors, while age and delayed sternal closure showed only trends toward significance. To predict the occurrence of adverse events from VIS and RACHS-1, the area under the curve was 0.73 (95%CI 0.66 - 0.79). Conclusion: Adverse events were quite frequent in children after cardiac surgery, especially those related to devices. The VIS and RACHS-1, used together, predicted the occurrence of adverse events well in this pediatric sample.
RESUMO Objetivo: Avaliar a ocorrência de eventos adversos em pós-operatório cardíaco em uma unidade de terapia intensiva pediátrica e estabelecer eventuais associações das características dos pacientes e a possibilidade de predizer tais eventos. Métodos: Coorte histórica de 7 dias de pós-operatório cardíaco, de abril a dezembro de 2019, por revisão de prontuários de pacientes com recuperação em unidade de terapia intensiva pediátrica. Foram revisados: características demográficas e clínico-laboratoriais, escores de gravidade dos pacientes e eventos adversos selecionados agrupados em: relacionados a dispositivos, a aspectos cirúrgicos e a aspectos não cirúrgicos. Resultados: Foram incluídos 238 prontuários. Ocorreu pelo menos um evento adverso em 110 pós-operatórios (46,2 %). O número total de eventos adversos foi 193 (81%), sendo mais frequente a complicação com cateteres vasculares, seguida de parada cardíaca, sangramento e reexploração cirúrgica. Na análise univariada, escore vasoativo-inotrópico (VIS- vasoactive-inotropic score), Risk Adjustment in Congenital Heart Surgery (RACHS-1) score, idade, Pediatric Index of Mortality (PIM-2), tempo de circulação extracorpórea e de clampeamento aórtico foram estatisticamente significantes com eventos adversos. Na análise multivariável, VIS ≥ 20 (OR 2,90; p = 0,004) e RACHS-1 ≥ 3 (OR 2,11; p = 0,019) mostraram-se relevantes e com significância estatística, enquanto idade e fechamento tardio do esterno possuíam apenas tendência a essa associação. Considerando a previsão de ocorrência de eventos adversos a partir dos valores de escore vasoativo-inotrópico e de RACHS-1, a área sob a curva mostrou valor de 0,73 (IC95% 0,66 - 0,79). Conclusão: A frequência de eventos adversos foi expressiva e aqueles relacionados a dispositivos foram os mais frequentes. O VIS e o RACHS-1, utilizados em conjunto, foram capazes de predizer a ocorrência de eventos adversos nesta amostra pediátrica.
RESUMO
La cirugía de revascularización coronaria (CABG) es el estándar de tratamiento para la revascularización de la enfermedad de la arteria coronaria izquierda y/o de tres vasos. La cirugía coronaria sin bomba (OPCAB) evita el uso de derivación cardiopulmonar y puede mejorar los resultados a largo plazo al reducir las tasas de lesión miocárdica perioperatoria, accidente cerebrovascular (ACV), deterioro neurocognitivo y mortalidad de causa cardiaca. En la actualidad, se han llevado a cabo diversos ensayos clínicos desde la popularización del OPCAB en la década de los 90. Sin embargo, hasta el momento no se ha demostrado ningún beneficio del OPCAB en comparación con la cirugía tradicional a pesar de las reducciones favorables a corto plazo en los requerimientos de transfusión y otras complicaciones postoperatorias. Además, OPCAB se asocia con una revascularización miocárdica menos eficaz y no previene por completo las complicaciones tradicionalmente asociadas con la circulación extracorpórea (CEC). Este artículo revisa la evidencia actual de OPCAB en comparación con CABG tradicional en cuanto a los resultados clínicos a corto y largo plazo. Se analizan los resultados de la cirugía coronaria sin circulación extracorpórea (CEC) , comparándola con la cirugía convencional (con CEC). La revascularización coronaria sin CEC presenta resultados similares a la convencional, siempre que se cumplan determinadas condiciones en la selección de los pacientes. Una de ellas, muy importante, es la mayor experiencia del cirujano con el procedimiento.
The results of coronary artery revascularization performed without extracorporeal circulation (off pump) are compared to those of the traditional ("on pump") procedure. Compliance with selective conditions are required to obtain similar results. The most important being the experience of the surgeon performing the off pump procedure.

Abstract Background The SHARPEN score was developed to predict in-hospital mortality in patients hospitalized for infective endocarditis (IE), undergoing or not undergoing cardiac surgery. A comparison with other available scores has not yet been carried out. Objective To evaluate the performance of the SHARPEN score in predicting in-hospital mortality in patients hospitalized for IE undergoing cardiac surgery and compare it with that of both nonspecific and IE-specific surgical scores. Methods Retrospective cohort study including all admissions of patients ≥18 years who underwent cardiac surgery due to active IE (modified Duke criteria) at a tertiary care university hospital between 2007 and 2016. The SHARPEN score was compared to the EuroSCORE, EuroSCORE II, STS-IE, PALSUSE, AEPEI, EndoSCORE and RISK-E scores. Differences P<0.05 were considered statistically significant. Results A total of 105 hospitalizations of 101 patients (mean age 57.4±14.6 years; 75.2% male) were included. The median SHARPEN score was 11 (9-13) points. The observed in-hospital mortality was 29.5%. There was no statistically significant difference in observed vs. estimated mortality (P = 0.147), with an area under the ROC curve of 0.66 (P = 0.008). In comparison with the other scores, no difference was observed in discriminative ability. The statistics of the SHARPEN score at a cutoff >10 points — positive predictive value (PPV): 38.1%, 95%CI:30.4-46.6; negative predictive value (NPV): 80.0%, 95%CI:69.8-87.4; and accuracy: 58.1%, 95%CI:48.1-67.6 — showed overlapping 95%CIs, indicating no significant difference between scores. Conclusions The SHARPEN score did not present parameters with a significant difference in relation to the other scores analyzed; despite the easy obtainment of its few variables, it has limited applicability in clinical practice, like other existing scores.
RESUMO
SUMMARY OBJECTIVE: This study aimed to evaluate postoperative pain and quality of life in patients undergoing median sternotomy. METHODS: A cohort study was carried out on a sample of 30 patients who underwent elective cardiac surgery by longitudinal median sternotomy. Patients were interviewed at Intensive Care Unit discharge and hospital discharge, when the Visual Numeric Scale and the Brief Pain Inventory were applied, and 2 weeks after hospital discharge, when the World Health Organization Quality of Life-Bref questionnaire was administered. The normality of the results was analyzed by the Shapiro-Wilk test, and Wilcoxon Rank Sum and McNemar tests were utilized for the analysis of numerical and categorical variables. For correlation between numerical variables, Spearman's linear correlation test was applied. To compare numerical variables, Mann-Whitney U and Kruskal-Wallis tests were applied. Differences between groups were considered significant when the p-value was <0.05. RESULTS: Between Intensive Care Unit and hospital discharge, there was a reduction in median pain intensity assessed by the Visual Numeric Scale from 5.0 to 2.0 (p<0.001), as well as in eight Brief Pain Inventory parameters: worst pain intensity in the last 24 h (p=0.001), analgesic relief (p=0.035), and pain felt right now (p=0.009); and in interference in daily activities (p<0.001), mood (p=0.017), ability to walk (p<0.001), relationship with other people (p=0.005), and sleep (p=0.006). Higher pain intensity at Intensive Care Unit discharge was associated with worse performance in the psychological domain of quality of life at out-of-hospital follow-up. CONCLUSION: Proper management of post-sternotomy pain in the Intensive Care Unit may imply better quality of life at out-of-hospital follow-up.
RESUMO
ABSTRACT Introduction: The Impella ventricular support system is a device that can be inserted percutaneously or directly across the aortic valve to unload the left ventricle. The purpose of this study is to determine the role of Impella devices in patients with acute cardiogenic shock in the perioperative period of cardiac surgery. Methods: A retrospective single-surgeon review of 11 consecutive patients who underwent placement of Impella devices in the perioperative period of cardiac surgery was performed. Patient records were evaluated for demographics, indications for placement, and postoperative outcomes. Results: Impella devices were placed for refractory cardiogenic shock preoperatively in 6 patients, intraoperatively in 4 patients, and postoperatively as a rescue in 1 patient. Seven patients received Impella CP, 1 Impella RP, 1 Impella CP and RP, and 2 Impella 5.0. Additionally, 3 patients required preoperative venovenous extracorporeal membrane oxygenation (VV-ECMO), and 1 patient required intraoperative venoarterial extracorporeal membrane oxygenation (VA-ECMO). All Impella devices were removed 1 to 28 days after implantation. Length of stay in the intensive care unit stay ranged from 2 to 53 days (average 23.9±14.6). The 30-day and 1-year mortality were 0%. Ten of 11 patients were alive at 2 years. Also, 1 patient died 18 months after surgery from complications of coronavirus disease (Covid-19). Device-related complications included varying degrees> of hemolysis in 8 patients (73%) and device malfunction in 1 patient (9%). Conclusions: The Impella ventricular support system can be combined with other mechanical support devices for additional hemodynamic support. All patients demonstrated myocardial recovery with no deaths in the perioperative period and in 1-year of follow-up. Larger studies are necessary to validate these findings.
RESUMO
Abstract Paravalvular leakage (PVL) after mitral valve replacement is a troublesome complication that may lead to severe symptoms and reoperation. Previous case reports on total thoracoscopic cardiac surgery without aortic cross-clamping for repairing late PVL are rare. We describe a 64-year-old man who had undergone aortic and mitral valve replacement via median sternotomy eight years earlier, and who recently developed cardiac failure due to severe tricuspid regurgitation (TR) and PVL in the posterior mitral annulus. During total thoracoscopic surgery with using the beating heart technique, direct closure of the PVL was achieved via pledgeted mattress sutures, and tricuspid valvuloplasty was routinely performed to treat TR. This case indicated that total thoracoscopic surgery on a beating heart may be an excellent option for treating PVL concomitant with TR.
RESUMO
ABSTRACT The presence of persistent left superior vena cava to the left atrium connection without an innominate vein may give rise to technical challenges during intracardiac repair. In this report, the end-to-side anastomosis technique of the persistent left superior vena cava to the right superior vena cava is discussed in a patient with tetralogy of Fallot associated with persistent left superior vena cava draining directly into the left atrium. A successful end-to-side anastomosis between the persistent left superior vena cava and the right superior vena cava was performed and short-term anastomosis patency was documented via angiography.
RESUMO
ABSTRACT Introduction: Aortic stenosis (AS) is the most common valvular heart disease and the most common indication for aortic valve replacement in adults. Aortic valve neocuspidization (AVNeo) with fixed autologous pericardium, also known as the Ozaki procedure, is a possible alternative treatment of AS. Autopericardial valves save the dynamics and physiological anatomy of the aortic root, however, the service life of autopericardial leaflets is limited. There is no data about factors that may influence the development of AVNeo insufficiency. Here, we assessed the effect of autopericardial leaflet symmetry on the development of aortic insufficiency after Ozaki procedure. Methods: This study included 381 patients with AS who underwent Ozaki procedure. Patients were divided into group 1 (171 patients with symmetric aortic root) and group 2 (210 patients with asymmetric aortic root). Results: The maximum observation period was up to 65 months. Sixteen cases of aortic insufficiency were detected in group 1, and 33 cases were detected in group 2. Based on the results of Cox regression, the predictors of aortic insufficiency in the late postoperative period are age and asymmetry of neocusps. According to results of Kaplan-Meier analysis, insufficiency of AVNeo in the maximum follow-up period after surgical correction of AS for group 1 patients was significantly lower than for group 2 patients (P=0.006). Conclusion: Asymmetric neocusps increase the risk of aortic insufficiency in the mid-term period after Ozaki procedure. And the older the patients at the time of surgery, the less likely they develop AVNeo insufficiency.
RESUMO
Abstract Introduction: Arterial lactate, mixed venous O2 saturation, venous minus arterial CO2 partial pressure (Pv-aCO2) and the ratio between this gradient and the arterial minus venous oxygen content (Pv-aCO2/Ca-vO2) were proposed as markers of tissue hypoperfusion and oxygenation. The main goals were to characterize the determinants of Pv-aCO2 and Pv-aCO2/Ca-vO2, and the interchangeability of the variables calculated from mixed and central venous samples. Methods: 35 cardiac surgery patients were included. Variables were measured or calculated: after anesthesia induction (T1), end of surgery (T2), and at 6-8 hours intervals after ICU admission (T3 and T4). Results: Macrohemodynamics was characterized by increased cardiac index and low systemic vascular resistances after surgery (p < 0.05). Hemoglobin, arterial-pH, lactate, and systemic O2 metabolism showed significant changes during the study (p < 0.05). Pv-aCO2 remained high and without changes, Pv-aCO2/Ca-vO2 was also high and decreased at T4 (p < 0.05). A significant correlation was observed globally and at each time interval, between Pv-aCO2 or Pv-aCO2/Ca-vO2 with factors that may affect the CO2 hemoglobin dissociation. A multilevel linear regression model with Pv-aCO2 and Pv-aCO2/Ca-vO2 as outcome variables showed a significant association for Pv-aCO2 with SvO2, and BE (p < 0.05), while Pv-aCO2/Ca-vO2 was significantly associated with Hb, SvO2, and BE (p < 0.05) but not with cardiac output. Measurements and calculations from mixed and central venous blood were not interchangeable. Conclusions: Pv-aCO2 and Pv-aCO2/Ca-vO2 could be influenced by different factors that affect the CO2 dissociation curve, these variables should be considered with caution in cardiac surgery patients. Finally, central venous and mixed values were not interchangeable.

RESUMO
ABSTRACT Objectives: to analyze the influence of sociodemographic and clinical variables, as well as the surgical checklist adherence score, on the occurrence of surgical site infection among patients undergoing myocardial revascularization. Methods: an observational, longitudinal, retrospective study was conducted at a university hospital, involving 266 medical records of patients who underwent myocardial revascularization surgery. Instruments containing sociodemographic, clinical, and infection-related variables were used, along with the Perioperative Surgical Safety Checklist. Descriptive, bivariate, and logistic regression analyses were employed. Results: surgical site infection occurred in 89 (33.5%) patients. There was a statistically significant association between body temperature outside the range of 36 degrees Celsius to 36.5 degrees Celsius (p=0.01), the presence of invasive devices (p=0.05), surgical procedures with the anticipation of critical events (p<0.001), and the occurrence of infection. Conclusions: body temperature, the presence of invasive devices, and surgical procedures with the anticipation of critical events were significant factors contributing to an increased risk of infection.

RESUMO
ABSTRACT Introduction: The increasing worldwide number of adults with congenital heart disease (CHD) demands greater attention from health professionals. The purpose of this report is to describe the clinical demographic profile, frequency, and invasive treatment status of adults with CHD in a public reference hospital in northeastern Brazil. Methods: This is a retrospective cross-sectional study including 704 patients attended between August 2016 and August 2020. Data were collected from virtual database. Results: Patients' age varied from 17 to 81 years (mean 32±14; median 27 years); 294 (41.8%) patients were male, and 410 (58,2%) were female; 230 (32,7%) had diagnosis from age 18 and up. Cardiac complexity categories were "simple defects" (134 [19%] patients), "moderate complexity" (503 [71.5%]), and "great complexity" (67 [9.5%]). Atrial septal defect (ASD) was diagnosed in 216 (30.7%) patients, ventricular septal defect (VSD) in 101 (14.3%), tetralogy of Fallot in 93 (13.2%), and other CHD in 294 (41.8%). New York Heart Association (NYHA) functional classes were I (401 [57%]), II (203 [28.8%]), III (76 [10.8%]), and IV (24 [3.4%]). Complications were arrhythmias (173 [24%]) and severe pulmonary hypertension (69 [9.8%]). Invasive treatments were corrective surgery (364 (51.6%]), reoperation (28 [4.0%]), palliation (11 [1.6%]), interventional catheterization (12 [1.7%]), surgery plus interventional catheterization (5 [0.7%]), and preoperation (91 [12.9%]). Treatment was not required in 102 (14,5%) patients, and 91 (12.9%) were inoperable. Conclusion: The leading diagnosis was ASD. Frequency of unrepaired patients was high, mainly ASD, due to late diagnosis, which favored complications and denotes a matter of great concern.
RESUMO
SUMMARY OBJECTIVE: The aim of this study was to investigate the efficacy of vasoactive inotrope score at the 24th postoperative hour for mortality and morbidity in elective adult cardiac surgery. METHODS: Consecutive patients who underwent elective adult coronary artery bypass and valve surgery in a single tertiary center for cardiac surgery between December 2021 and March 2022 were prospectively included. The vasoactive inotrope score was calculated with the dosage of inotropes that were continuing at the 24th postoperative hour. Poor outcome was defined as any event of perioperative mortality or morbidity. RESULTS: The study included 287 patients, of whom 69 (24.0%) were on inotropes at the 24th postoperative hour. The vasoactive inotrope score was higher (21.6±22.5 vs. 0.94±2.7, p=0.001) in patients with poor outcome. One unit increase in the vasoactive inotrope score had an odds ratio of 1.24 (95% confidence interval: 1.14-1.35) for poor outcome. The receiver operating characteristic curve of vasoactive inotrope score for poor outcome had an area under the curve of 0.857. CONCLUSION: Vasoactive inotrope score at the 24th hour can be a very valuable parameter for risk calculation in the early postoperative period.
RESUMO
ABSTRACT Objective: to compare cardiac anxiety symptoms in patients undergoing coronary artery bypass graft and valve surgery repair in the preoperative period, on the day of hospital discharge and on the first return visit after hospital discharge. Methods: an observational study, carried out in inpatient units and in outpatient clinic of a university hospital. Data were collected through interviews. Cardiac anxiety symptoms were assessed using the Cardiac Anxiety Questionnaire. Results: we observed the effect of time on cardiac anxiety symptoms of patients undergoing coronary artery bypass graft in the total score and in the "Avoidance" domain at discharge and at the first return visit. In patients undergoing valve repair surgery, the effect of time on symptoms was observed only in the first return visit, when compared with the preoperative period. Conclusion: the findings revealed increased cardiac anxiety symptoms in the postoperative period, discharge and first return, when compared to the preoperative period.

Métodos: estudio observacional, realizado en las unidades de hospitalización y en la consulta externa de un hospital universitario. Los datos fueron recolectados a través de entrevistas. Los síntomas de ansiedad cardíaca se evaluaron mediante el Cuestionario de Ansiedad Cardíaca. Resultados: observamos el efecto del tiempo sobre los síntomas de ansiedad cardiaca de los pacientes sometidos a cirugía de revascularización miocárdica en la puntuación total y en el dominio "Evitación" al alta y en la primera visita de regreso. En pacientes sometidos a corrección quirúrgica de cardiopatía valvular, el efecto del tiempo sobre los síntomas se observó sólo en la primera visita de seguimiento, en comparación con el período preoperatorio. Conclusión: los hallazgos revelaron un aumento de los síntomas de ansiedad cardiaca en el postoperatorio, alta y primer retorno, en comparación con el preoperatorio.
RESUMO Objetivo: comparar os sintomas de ansiedade cardíaca em pacientes submetidos às cirurgias de revascularização do miocárdio e de correção de valvopatias no pré-operatório, no dia da alta hospitalar e no primeiro retorno após a alta hospitalar. Métodos: estudo observacional, realizado nas unidades de internação e no ambulatório de um hospital universitário. Os dados foram coletados por entrevistas. Os sintomas de ansiedade cardíaca foram avaliados utilizando o Questionário de Ansiedade Cardíaca. Resultados: observamos o efeito do tempo nos sintomas de ansiedade cardíaca dos pacientes submetidos à cirurgia de revascularização do miocárdio no escore total e no domínio "Evitação" na alta e no primeiro retorno. Em pacientes submetidos à correção cirúrgica de valvopatias, observou-se o efeito do tempo nos sintomas apenas no primeiro retorno, quando comparados com o pré-operatório. Conclusão: os achados revelaram o aumento dos sintomas de ansiedade cardíaca no pós-operatório, alta e primeiro retorno, quando comparados com o pré-operatório.
RESUMO
Resumen Introducción: La saturación de oxígeno y el lactato son marcadores de hipoxia tisular, se obtienen de muestra venosa mezclada en arteria pulmonar o venosa central. Se desconoce el comportamiento simultáneo de estos parámetros en el postoperatorio de cirugía cardiaca. Objetivo: Caracterizar la saturación de oxígeno y lactato del circuito venoso-arterial del paciente postoperado de cirugía cardiaca. Métodos: Diseño transversal analítico. En pacientes consecutivos postoperados de cirugía cardiaca se obtuvieron lactato sérico y saturación de oxígeno del circuito venoso-arterial. Las variables se informaron con mediana (percentiles 25 y 75). Se analizaron con ANOVA de Kruskal-Wallis y ajuste respectivo, correlación de Spearman, el estadístico descriptivo de Bland-Altman y coeficiente de correlación intraclase (intervalo de confianza al 95%). Una p < 0.05 se consideró significativa. Resultados: Se estudiaron 244 muestras sanguíneas de 61 pacientes. Mujeres 30 (49%). Saturación de oxígeno y lactato fueron: arterial 98 (95.3, 99.4)% y 1.7 (1,1, 2.1); venosa periférica 85 (75.4, 94)% y 1.9 (1.35, 2.3); venosa central 68.8 (58.74, 70.2)% y 1.8 (1.3, 2.3); venosa central mezclada 66.8 (61.2, 73.1)% y 1.8 (1.3, 2.2), p < 0.05. El mejor coeficiente de correlación intraclase para la saturación de oxígeno fue de vena central a vena central mezclada: 0.856 (0.760, 0.914); del lactato: 0.954 (0.923, 0.972). Conclusiones: La saturación de oxígeno difiere en el circuito venoso-arterial a diferencia del lactato, donde son similares. Los mejores valores del coeficiente de correlación intraclase para el lactato y la saturación de oxígeno fueron los obtenidos en vena central y vena central mezclada.
Abstract Introduction: Oxygen saturation and lactate are markers of tissue hypoxia; they are obtained from central venous and mixed venous sample of the pulmonary artery. The simultaneous behavior of these parameters in the postoperative period of cardiac surgery is unknown. Objective: To characterize the lactate and oxygen saturation of the venous-arterial circuit of the postoperative patient from cardiac surgery. Methods: Design: Analytical cross-sectional. In consecutive patients after cardiac surgery, serum lactate and oxygen saturation of the venous-arterial circuit were obtained. The variables were reported with median (25.75 percentiles). They were analyzed with Kruskal-Wallis ANOVA and respective adjustment, Spearman correlation, the descriptive Bland-Altman statistic and intraclass correlation coefficient (95% confidence interval). A p < 0.05 was considered significant. Results: 244 blood samples from 61 patients were studied. Women 30 (49%). (Oxygen saturation) [lactate] were: arterial 98 (95.3, 99.4%) and 1.7 (1.1, 2.1); peripheral venous 85 (75.4, 94%) and [1.9 (1.35, 2.3)]; central venous 68.8 (58.74, 70.2%) and 1.8 (1.3, 2.3); mixed central venous 66.8 (61.2, 73.1%) and 1.8 (1.3, 2.2), p < 0.05. The best intraclass correlation coefficient for oxygen saturation were from central vein to mixed central vein 0.856 (0.760,0.914); and lactate: 0.954 (0.923, 0.972). Conclusions: The oxygen saturation differs in the venous-arterial circuit unlike lactate where they are similar. The best values of the intraclass correlation coefficient for lactate and oxygen saturation were those obtained in central vein and mixed central vein.
