RESUMO
Objetivo: Analisar as solicitações de transfusões sanguíneas encaminhadas à central transfusional do Hospital Universitário Evangélico de Curitiba, buscando identificar o tipo e quantidade de hemocomponentes transfundidos nesse período, bem como o perfil dos pacientes receptores e as razões pelas quais eles foram submetidos a essa terapia. Material e Métodos: Foram analisadas todas as fichas de requerimento de transfusão encaminhadas à central transfusional do hospital no período de agosto a dezembro de 2013, sendo incluídas no estudo apenas aquelas que resultaram em transfusão efetiva. Foram obtidas informações referentes às características dos pacientes, aos hemocomponentes transfundidos e às indicações relativas a cada um deles. Resultados: A idade média foi de 50 anos, com predominância nos homens (58,7%). De forma geral, foi observado que a maioria dos procedimentos foi realizada na enfermaria (47,7%). O hemocomponente mais transfundido foi o concentrado de hemácias (74,1%). A principal indicação para a transfusão de concentrado de hemácias foi por anemia em paciente com doença cardíaca, pulmonar ou cerebrovascular (51,9%). O tipo sanguíneo predominante na nossa pesquisa foi o O positivo (43%). Conclusão: O fracionamento do sangue total em hemocomponentes levou a um maior benefício clínico para os pacientes que recebem as transfusões, acarretando em um maior número de pacientes atendidos pela terapêutica transfusional e menor desperdício desse material nobre. O hemocomponente mais transfundido foi o concentrado de hemácias, não sendo realizado nenhum procedimento utilizando-se de sangue total. Dentre os procedimentos, apenas 16,4% foram indicados devido a procedimento cirúrgico.
Objective: To analyze the requests for blood transfusions that were sent to the transfusion center of Hospital Universitário Evangélico de Curitiba, seeking to identify the type and amount of blood products transfused during this period as well as the profile of the recipient patients and the reasons why they were subjected to this therapy. Material and Methods: All records of transfusion requests sent to the hospital transfusion center from August 2013 to December of that same year were analyzed, but only those that resulted in effective transfusion were included in the study. Information regarding the characteristics of patients, transfused blood products and indications for each of them were obtained. Results: The mean age was 50 years, predominantly in men (58.7%). In general, we observe that most of the procedures was performed on the ward (47.7%). The most transfused blood component was the red blood cells (74.1%). The main indication for transfusion of red blood cells is anemia in patients with heart, lung or cerebrovascular disease (51.9%). The predominant blood type in our survey was the O positive (43%). Conclusion: The fractionation of whole blood into blood components led to a greater clinical benefit for patients receiving transfusions , resulting in a greater number of patients treated by transfusion therapy and less waste of this noble material. The most transfused blood component was the red blood cells , not being carried out no procedure using whole blood . Among the procedures , only 16.4 % were indicated due to a surgical procedure.
RESUMO
BACKGROUND: Despite advances in medical therapy, cardiovascular disease, mainly coronary artery disease (CAD), remains the leading cause of mortality among patients with diabetes mellitus (DM). The objective of the present study was to assess the effectiveness of dipyridamole stress echocardiography in identify diabetic patients at high risk for cardiovascular events. METHODS: Dipyridamole stress echocardiography was administered to 483 diabetic patients (294 women; mean age 63.41 ± 11.28 years) between July 2006 and December 2012. RESULTS: Follow-up data were available for 264 patients (163 women; mean age 64.3 ± 10.5 years): 250 with a negative stress echocardiography and 14 with a positive stress echo. During a mean follow-up time of 18 ± 14 months, a cardiovascular event occurred in 18 (6.8%) patients, 12 (4.8%) in patients with a negative stress echo (n = 250) during a mean follow-up period of 20 ± 16 months and 6 (42%) in patients with positive stress echo (n = 14) during a mean follow-up of 13 ± 13 months. The positive and negative predictive values of stress echocardiography were 42% and 96% respectively. The accuracy value was 92%. A Cox regression model showed that CAD (hazard ratio [HR] 5.4, 95% confidence interval [CI] 1.9-15.4; p = 0.002) and positive stress echocardiography (HR 7.1, 95% CI 2.5-20.5; p < 0.001) were significant predictors of cardiovascular events. CONCLUSIONS: For patients with diabetes, a negative dipyridamole stress echocardiogram predicts favorable outcome during the first year of follow-up. A new stress imaging test should be done after 12 months in diabetic patients.
