ABSTRACT
Abstract Background: The indiscriminate use of blood transfusion in surgery has been associated with increased risk of infection and increased length of hospital stay. Objective: To identify the average amount of bleeding and rates of transfusion of blood products in the postoperative period of patients undergoing cardiac surgery in a cardiology center. Methods: Medical records of patients who underwent myocardial revascularization surgery and/or heart valve replacement with use of cardiopulmonary bypass (CPB) were analyzed. Perioperative data such as CPB time, hematocrit and hemoglobin values were collected after surgery. The amount of bleeding (mL), blood transfusion (IU), clinical complications and time of hospitalization were also recorded. The correlation between bleeding in the postoperative period and blood transfusion was performed using the Spearman correlation. A p < 0.05 was considered statistically significant. Results: A total of 423 patients undergoing coronary artery bypass grafting (51.5%) or heart valve replacement (33.6%) were included. During the first 24 hours, the average bleeding volume was 353.3 ± 268.3 mL. Transfusion of blood products was required in 40.1% of cases, most frequently (70.6%) in the immediate postoperative period. Red blood cell concentrate was the most frequently used product (22.9% and 60%). Conclusion: The occurrence of bleeding in the cases was low, and when transfusion of blood components was indicated, red blood cell concentrates were the most widely used component.

OBJECTIVE: Verifying the clinical-surgical profile and the results of patients monitored in an surgical wound ambulatory after a cardiac surgeries. METHODS: This is a historical cohort research with patients submitted to cardiac surgery and monitored for a year in an outpatient surgical wound clinic from a hospital specialized in cardiology. The study analyzed the prevalent microorganisms in infections, the products used in the dressings, the time of follow-up, and the type of therapy established in the dressings. RESULTS: Among the 150 patients, most were sexagenarians (61.7 ± 11.4 years), hypertensive patients (75%), and diabetic (44.7%). There were 12 patients with mediastinitis (8%) and 44 with surgical site infection (29.3%). Fatty acids (80%) and calcium alginate (19%) were used for wound healing. The mean follow-up time was 35 ± 71 days. CONCLUSION: Sexagenary, hypertensive, diabetic and revascularized patients constituted the population monitored in the wounds outpatient clinic. The SSI and mediastinitis rates found were acceptable and similar to those in literature.

Resumo OBJETIVO Verificar o perfil clínico-cirúrgico e os resultados de pacientes acompanhados em um ambulatório de ferida operatória após cirurgia cardíaca. MÉTODOS Coorte histórica com pacientes submetidos à cirurgia cardíaca e acompanhados por um ano em um ambulatório de feridas de um hospital especializado em cardiologia. Foram analisados os micro-organismos predominantes nas infecções, os produtos utilizados nos curativos, tempo de acompanhamento e o tipo de terapêutica instituída nos curativos. RESULTADOS Entre os 150 pacientes, predominaram sexagenários (61,7 ± 11,4 anos), hipertensos (75%), diabéticos (44,7%). Evidenciou-se 12 pacientes com mediastinite (8%) e 44 com infecção de sítio cirúrgico (29,3%). Utilizou-se para realização dos curativos os ácidos graxos (80%) e alginato de cálcio (19%). O tempo de acompanhamento foi de 35 ±71 dias. CONCLUSÃO Pacientes sexagenários, hipertensos, diabéticos e revascularizados constituíram a população acompanhada no ambulatório de feridas. As taxas de ISC e mediastinite encontradas foram aceitáveis e semelhantes às da literatura.
Resumen OBJETIVO Verificar el perfil clínico-quirúrgico y los resultados de pacientes acompañados en un ambulatorio de heridas operatorias después de cirugía cardiaca. MÉTODO Cohorte histórica con pacientes sometidos a la cirugía cardiaca y acompañados por un año en el ambulatorio de heridas de un hospital especializado en cardiología. Fueron analizados los microorganismos predominantes en las infecciones, los productos utilizados en las curaciones, el tiempo de seguimiento, o el tipo de tratamiento utilizado en las curaciones. RESULTADOS Entre los 150 pacientes predominaron el sexo masculino (58%), sexagenarios (61,7 ± 11,4 años), hipertensos (75%), diabéticos (44.7%). Se evidenciaron 12 pacientes con mediastinitis (8%) y 44 con infección en el sitio quirúrgico (29.3%). Se utilizó en las curaciones fueron los ácidos grasos (80%) y el alginato de calcio (19%). El tiempo medio de seguimiento fue de 35 ± 71 días.

Abstract Background: Mediastinitis is a severe surgical complication of low incidence, but high lethality. Scores used in the preoperative period to stratify the risk of postoperative mediastinitis may contribute to improve the results. Objective: To test the applicability of the MagedanzSCORE in predicting the risk factors for mediastinitis in patients undergoing coronary artery bypass grafting at a cardiology reference hospital. Methods: Historical cohort study with adult patients who underwent coronary artery bypass grafting. The analyzed variables were contemplated in the MagedanzSCORE: reoperation, chronic obstructive pulmonary disease (COPD), obesity, class IV unstable angina, polytransfusion therapy, mediastinitis and death as outcome variables. Results: Of the 1.322 patients examined, 56 (4.2%) developed mediastinitis. Of these, 26 (46.4%) were classified as high risk for mediastinitis and 15 (26.8%) at very high risk for mediastinitis. Three of the five variables of the Magendanz Score showed statistically significant differences: reoperation, COPD and obesity. Class IV unstable angina and postoperative polytransfusion were not associated with mediastinitis after coronary artery by-pass grafting. The area under the ROC curve was 0.80 (CI 95% 0.73 - 0.86), indicating the model's satisfactory ability to predict the occurrence of mediastinitis. Conclusion: The tool was useful in the preoperative assessment demonstrating the risk for mediastinitis in this population of intensive care patients.

Resumo Fundamento: A mediastinite é uma complicação cirúrgica grave de baixa incidência, porém com alto poder de letalidade. Escores utilizados no período pré-operatório para estratificar o risco de sua ocorrência podem contribuir para melhorar os resultados. Objetivo: Testar a aplicabilidade do MagedanzSCORE em prever risco de mediastinite em pacientes submetidos à cirurgia de revascularização do miocárdio (CRM) em um hospital de referência em cardiologia. Métodos: Estudo de coorte histórica conduzido com pacientes adultos submetidos à CRM. As variáveis analisadas foram as contempladas no MagedanzSCORE: reintervenção cirúrgica, doença pulmonar obstrutiva crônica (DPOC), obesidade, angina estável classe IV/angina instável, politransfusão sanguínea, mediastinite e óbito como variáveis de desfecho. Resultados: Dentre os 1.322 pacientes analisados, 56 (4,2%) desenvolveram mediastinite. Destes, 26 (46,4%) foram classificados com risco elevado e 15 (26,8%) com risco muito elevado. Três das cinco variáveis do escore apresentaram diferenças estatisticamente significativas: reintervenção cirúrgica, DPOC e obesidade. Angina classe IV/instável e politransfusão (pós-operatória) não apresentaram associação com mediastinite após a CRM. A área sob a curva ROC foi de 0,80 (IC 95% 0,73 - 0,86), demonstrando capacidade satisfatória do modelo em prever a ocorrência de mediastinite. Conclusão: O instrumento mostrou-se útil para auxiliar na avaliação pré-operatória por apontar o risco de mediastinite nesta população de pacientes de cuidados intensivos.
