ABSTRACT

ABSTRACT Introduction: Patient blood management (PBM) programs are associated with better patient outcomes, a reduced number of transfusions and cost-savings The Clinical Decision Support (CDS) systems are valuable tools in this process, but their availability is limited in developing countries This study assesses the feasibility and effectiveness of an adapted CDS system for low-income countries. Methods: This was a prospective study of the PBM program implementation, in a 200-bed tertiary hospital, between February 2019 and May 2020. Outcome measures were red blood cell (RBC), fresh frozen plasma (FFP) and platelet unit transfusions, the transfusion of a single unit of red blood cells and an RBC adequacy index (RAI). Results: Comparing the post-PBM program era with the pre-PBM system era, there was a decrease in red blood cell transfusions (p = 0.05), with an increase in single unit red blood cell transfusions (p = 0.005) and RAI (p < 0.001). Conclusions: The PBM programs, including electronic transfusion guidelines with pre-transfusion medical auditing, was associated with improved transfusion practices and reduced product acquisition-related costs.

ABSTRACT

Abstract Objective Preoperative anemia in orthopedic patients is associated with higher allogeneic blood transfusion rates and poorer outcomes. Up to 25% of the patients listed for major orthopedic surgery have some degree of anemia. Good perioperative patient blood management is essential to reduce the sequelae of anemia and the need for transfusions. We assessed the efficacy of rapid near-patient testing in conjunction with a dedicated preoperative anemia clinic for screening and treating primary total hip replacement (THR) patients for anemia. Methods A comparison of overall allogeneic blood transfusion rates was made for patients undergoing primary total hip replacement before and after the implementation of near-patient testing and of a dedicated preoperative anemia clinic over 1 year. A comparison was also performed between anemic patients who were referred to the clinic with those who were not referred. Preoperative hemoglobin levels, allogeneic blood transfusion rates and clinic treatment for 1,095 patients were reviewed. Results There was a significant decrease in transfusion rates in patients undergoing primary THR from 10.0 to 6.2% (p< 0.05; χ2 test) after the implementation of near-patient testing and of a dedicated preoperative anemia clinic pathway. The allogeneic blood transfusion rate for anemic patients who were treated in the clinic was 6.7% compared with 26.9% for patients who were anemic preoperatively but were not treated in the clinic (p< 0.05; Fisher exact test). On average, treatment in the pathway increased the hemoglobin of the patients by 20 g/L, from 104 g/L to 124 g/L (p< 0.001). Conclusions Near-patient testing, in conjunction with a dedicated preoperative anemia clinic, reduces perioperative allogenic blood transfusion requirements for patients undergoing primary THR by providing rapid identification and effective treatment of preoperative anemia.


Resumo Objetivo A anemia pré-operatória em pacientes ortopédicos, está associada a maiores taxas de transfusão de sangue alogênico, resultando em desfechos mais desfavoráveis. Até 25% dos pacientes encaminhados para cirurgia ortopédica de grande porte, apresentam algum grau de anemia. O controle adequado do sangue do paciente no perioperatório é essencial, a fim de reduzir as sequelas da anemia e a necessidade de transfusões. Avaliamos a eficácia do teste rápido, em conjunto com uma clínica especializada no tratamento da anemia pré-operatória, com o objetivo de detectar e tratar a anemia dos pacientes a serem submetidos a artroplastia total primária do quadril. Métodos A comparação das taxas totais de transfusão de sangue alogênico, foi realizada em pacientes submetidos a artroplastia total primária do quadril, antes e depois da implementação dos testes rápidos e da clínica especializada no tratamento da anemia pré-operatória ao longo de um ano. Também foi feita uma comparação entre os pacientes com anemia, que foram encaminhados para a clínica, com aqueles que não foram encaminhados. Foram revisados os níveis de hemoglobina pré-operatória, as taxas de transfusão de sangue alogênico e o tratamento clínico em 1.095 pacientes. Resultados Houve uma redução significativa nas taxas de transfusão, em pacientes submetidos à ATQ primária, caindo de 10,0% para 6,2% (p <0,05, teste χ2), após a implementação do teste rápido e da clínica especializada em anemia pré-operatória. A taxa de transfusão de sangue alogênico para pacientes anêmicos tratados na clínica foi de 6,7%, em comparação com 26,9% para pacientes anêmicos no pré-operatório, que não foram tratados na clínica (p <0,05, teste exato de Fisher). Em média, o tratamento na clínica aumentou a taxa de hemoglobina dos pacientes em 20 g/L, passando de 104 g/L para 124 g/L p <0,001. Conclusões O teste rápido, juntamente com a clínica especializada no tratamento da anemia pré-operatória, reduziu a necessidade de transfusão de sangue alogênico perioperatório, em pacientes submetidos a artroplastia total primária do quadril, proporcionando uma identificação rápida e um tratamento eficaz da anemia pré-operatória.

ABSTRACT

Abstract Objective To collect data on the role played by tranexamic acid in the prevention and management of blood loss in patients undergoing total hip arthroplasty and total knee arthroplasty. Methods In the present prospective, comparative study, 30 patients undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA) were randomly allocated into 1 of 2 groups with 15 patients each. Tranexamic acid was administered by intravenous and topical routes in the study group, but it was not administered in the control group. Preoperative blood parameters, intraoperative and postoperative blood loss, and need for blood transfusion were noted. Statistical analysis was performed using the chisquared test and the independent t-test. Results The study group had statistically significant higher postoperative hemoglobin values (p = 0.03), less difference between pre and postoperative hemoglobin value (p = 0.046), less difference between pre and postoperative packed-cell volume (p = 0.06), less intraoperative measured blood loss (p = 0.015), and less volume of blood collected in the drain (p = 0.0291) compared with the control group. There was also reduced frequency of blood transfusions in the study group (p = 0.0008). Conclusion Tranexamic acid is associated with reduced intra and postoperative blood loss and reduced frequency of blood transfusions in patients undergoing THA/TKA.


Resumo Objetivo Coletar dados sobre o papel desempenhado pelo ácido tranexâmico na prevenção e gerenciamento da perda de sangue em pacientes submetidos à artroplastia total do quadril (ATQ) e à artroplastia total do joelho (ATJ). Métodos Neste estudo prospectivo e comparativo, 30 pacientes submetidos à ATQ ou à ATJ foram alocados aleatoriamente em 1 de 2 grupos com 15 pacientes. O ácido tranexâmico foi administrado por rotas intravenosas e tópicas no grupo de intervenção, mas não foi administrado no grupo controle. Foram observados parâmetros sanguíneos pré-operatórios, perda de sangue intrae pós-operatória e necessidade de transfusão de sangue. A análise estatística foi realizada utilizando-se teste do qui-quadrado e o teste-t independente. Resultados O grupo de intervenção apresentou hemoglobina mais elevada no pósoperatório de forma estatisticamente significante (p = 0,03), menor diferença entre concentração de hemoglobina pré- e pós-operatória (p = 0,046), menor diferença entre volume de células embaladas pré- e pós-operatório (p = 0,06), menor perda de sangue intraoperatória medida (p = 0,015) e menor volume de sangue coletado na drenagem (p = 0,0291) em comparação com o grupo controle. Também houve redução da frequência de transfusões de sangue no grupo de intervenção (p = 0,0008). Conclusão O ácido tranexâmico está associado à redução da perda sanguínea intraoperatória e pós-operatória e à redução da frequência de transfusões de sangue em pacientes submetidos à ATQ/ATJ.

ABSTRACT

We report the successful management of a pregnant woman with para-Bombay phenotype. The woman received routine prenatal check-ups and underwent vaginal delivery in the Affiliated Shenzhen Maternity & Child Healthcare Hospital. Blood grouping at 12 weeks of pregnancy showed that the forward typing of the patient was group O, but reverse typing indicated group AB. Her ABO genotype was determined as ABO*A1.02/B.01. There was c.551-552del AG and c.880-882 del TT in the FUT1 gene, and 357C>T and 716G>A in the FUT2 gene. Thus, her FUT1 genotype was h1/h2 and FUT2 genotype was Se/Se. No significant abnormalities were found in the routine prenatal examination. A male infant was born vaginally at 39 +2 gestational weeks, who was grouped as B-positive without neonatal hemolytic disease. Para-Bombay is a rare blood group. It is necessary to clarify the blood type during prenatal examination and develop a management strategy for those with special blood groups to reduce the incidence of postpartum hemorrhage and ensure safe delivery.

ABSTRACT

Objective:To identify the risk factors for massive blood transfusion in pediatric living donor liver transplantation.Methods:The medical data of children underwent living donor liver transplantation in our hospital from April 2006 to April 2019 were retrospectively collected.Massive transfusion was defined as the administration of red blood cells > 1 fold of the total blood volume (70 ml/kg) during operation.Patients were assigned to massive transfusion group and non-massive transfusion group according to the volume of blood transfused during operation.Binary logistic regression analysis was used to identify the risk factors for massive blood transfusion during living liver transplantation.Results:A total of 95 pediatric patients were enrolled in this study, with 18 cases in massive transfusion group and 77 cases in non-massive transfusion group.The incidence of massive blood transfusion was 19% during operation.The results of logistic regression analysis showed that preoperative survival status of " hospitalization" ( OR=49.816, 95% CI 2.945-842.59, P=0.007), increased serum Cr concentrations ( OR=1.046, 95% CI 1.007-1.086, P=0.021), increased Pediatric End-Stage Liver Disease (PELD) or Model for End-Stage Liver Disease (MELD) score ( OR=1.215, 95% CI 1.046-1.411, P=0.011) and prolonged operation time( OR=1.623, 95% CI 1.133-2.327, P=0.008) were the independent risk factors for intraoperative massive blood transfusion in living donor liver transplantation, while increased recipient weight ( OR=0.856, 95% CI 0.761-0.962, P=0.009) was a protective factor for intraoperative massive blood transfusion. Conclusions:Preoperative survival status of " hospitalization", increased PELD or MELD score and prolonged operation time are independent risk factors, while increased pediatric weight is a protective factor for massive blood transfusion in pediatric living donor liver transplantation.

ABSTRACT

Ectopic pregnancy is a common gynecological acute abdomen disease. Once the pregnant tissue is ruptured, it will rapidly develop into hemorrhagic shock or even death. In recent years, blood transfusion from the body is widely used in the rescue of intra-abdominal hemorrhage of ectopic pregnancy, which can reduce the time of cross matching and blood collection, reduce the risk of allogeneic blood transfusion, and enable patients with hemorrhagic shock to receive timely and effective treatment. Hemolysis caused by autologous blood transfusion is rarely reported. Once hemolysis occurs, if it is not handled in time, severe cases can occur acute renal injury, hyperkalemia, or cardiac arrest or even sudden death. We retrospectively analyzed the diagnosis and treatment of a patient with hemolysis after autologous blood transfusion, suggesting that the adverse reactions of blood transfusion occur not only in allogeneic blood transfusion, but also in autologous blood transfusion. It should be handled reasonably in clinical work to reduce the occurrence of similar complications.

ABSTRACT

Objective:To investigate the effects of massive blood transfusion on serum electrolyte balance and serum levels of C-reactive protein (CRP), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in patients with severe trauma.Methods:A total of 83 patients with severe trauma who received treatment in Eastern District of LiHuili Hospital, Ningbo Medical Center between July 2019 and December 2020 were included in this study. All of them underwent blood transfusion. They were divided into massive blood transfusion group ( n = 29) and general blood transfusion group ( n = 54) according to the volume of blood transfused. Changes in coagulation function, electrolyte, liver-kidney function and inflammatory factor levels pre- and post-blood transfusion were compared between massive blood transfusion and general blood transfusion groups. Results:At 1 day after blood transfusion, activated partial thromboplastin time (APTT) and prothrombin time (PT) in the massive blood transfusion group were (45.64 ± 2.78) seconds and (17.71 ± 2.08) seconds, respectively, which were significantly longer than those in the general blood transfusion group [(41.02 ± 2.80) seconds, (15.35 ± 1.72) seconds, t = 5.53, 7.18, P < 0.05). At 1 day after blood transfusion, levels of tumor necrosis factor-α, interleukin-6 and C-reaction protein in the massive blood transfusion group were (1.84 ± 0.32) μg/L, (113.72 ± 13.34) ng/L, (28.94 ± 4.22) mg/L, respectively, which were significantly increased compared with those measured before blood transfusion [(1.28 ± 0.29) μg/L, (95.18 ± 10.64) ng/L, (16.48 ± 3.37) mg/L, t = 6.98, 5.85, 12.42, all P < 0.05]. Levels of tumor necrosis factor-α, interleukin-6 and C-reaction protein in the general blood transfusion group were (1.34 ± 0.27) μg/L, (98.54 ± 9.62) ng/L, (20.05 ± 3.30) mg/L, respectively at 1 day after blood transfusion, which were significantly increased compared with those measured before blood transfusion [(1.23 ± 0.26) μg/L, (94.22 ± 8.82) ng/L, (16.16 ± 3.39) mg/L, t = 2.15, 2.43, 6.04, all P < 0.05]. At 1 day after blood transfusion, serum levels of tumor necrosis factor-α and C-reaction protein in the massive blood transfusion group were significantly higher than those in the general blood transfusion group ( t = 7.53, 10.59, both P < 0.05). At 1 day after blood transfusion, serum levels of K + and Ca 2+ in the massive blood transfusion group were (3.56 ± 0.54) mmol/L and (1.87 ± 0.28) mmol/L, respectively, which were significantly lower than those in the general blood transfusion group [(4.27 ± 0.34) mmol/L, (2.26 ± 0.24) mmol/L, t = 7.34, 6.65, both P < 0.05]. Serum levels of alanine aminotransferase and aspartate aminotransferase in the massive blood transfusion group were (52.46 ± 20.27) U/L, (82.37 ± 31.15) U/L, respectively, which were significantly higher than those in the general blood transfusion group [(37.57 ± 10.31) U/L, (49.35 ± 10.14) U/L, t = 4.44, 7.14, both P < 0.05)]. The incidence of abnormal liver function in the massive blood transfusion group was significantly higher than that in the general blood transfusion group [62.07% (18/29) vs. 29.63% (16/54), χ2 = 10.13, P < 0.05)]. Conclusion:The internal environment of patients with severe trauma will change after massive blood transfusion. Their coagulation function, inflammatory factors, liver function and electrolyte balance should be monitored in time.

ABSTRACT

Objective:To investigate the clinical application effects of leukocyte-filtered blood transfusions.Methods:A total of 120 patients with massive bleeding who received transfusions of a large amount of blood in the First People's Hospital of Yongkang, China from January 2017 to December 2018 were included in this study. They were divided into a control group (even numbers) and an observation group (odd numbers) according to registration numbers. The control group was subjected to direct blood transfusion. The observation group was given leukocyte-filtered blood transfusions. Coagulation function index, hemorheological index, cellular immune function, immunoglobulin level, body temperature, and the incidence of febrile non-hemolytic transfusion reactions were compared between the two groups.Results:After blood transfusions, prothrombin time, activated partial thromboplastin time, thrombin time in the observation group were (12.39 ± 1.41) seconds, (26.84 ± 6.47) seconds, and (14.32 ± 3.14) seconds, which were significantly shorter than those in the control group [(15.54 ± 2.03) seconds, (34.23 ± 7.59) seconds, (20.98 ± 4.27) seconds, t = 9.872, 5.740, 9.733, all P < 0.05]. Hematocrit, erythrocyte sedimentation rate, and plasma viscosity in the observation group were (39.28 ± 2.17)%, (25.97 ± 4.10) mm/h, and (2.19 ± 0.45) mp·s respectively, and those in the control group were (34.64 ± 4.52)%, (21.85 ± 3.64) mm/h, and (1.76 ± 0.42) mp·s respectively. There were significant differences in these indices between the two groups ( t = 9.87, 5.74, 9.73, all P < 0.05). There were significant differences in CD 3+, CD 4/CD 8, immunoglobulin G, immunoglobulin A, and immunoglobulin M between before and after blood transfusions in the control group ( t = 5.99, 5.91, 5.77, 5.80, 5.85, all P < 0.05). There were no significant differences in these indices between before and after blood transfusions in the observation group (all P > 0.05). After blood transfusions, body temperature was significantly lower in the observation group than in the control group [(36.58 ± 0.50) ℃ vs. (37.16±0.57)℃, t = 5.95, P < 0.05]. The incidence of febrile non-hemolytic transfusion reactions was significantly lower in the observation group than in the control group (1.67% vs. 13.33%, χ2 = 5.88, P < 0.05). Conclusion:Leukocyte-filtered blood transfusions can effectively restore the patient's body temperature to normal, improve coagulation function index and hemorheological index, reduce the impact of blood transfusions on the patient's immune function, and reduce febrile non-hemolytic transfusion reactions.

ABSTRACT

Reconstructed rebalanced hemostasis exists in patients with liver cirrhosis, while such balance is unstable and can be easily broken by stress factors, which may lead to bleeding or thrombosis. There is a lack of effective strategies to prevent and solve the disrupted balance in clinic due to the complex pathogenesis of rebalanced hemostasis, limited testing methods, and insufficient awareness among clinicians. With reference to the articles in recent years, this article summarizes the mechanism of rebalanced hemostasis in liver cirrhosis and the causes of bleeding and thrombosis and discuss the association between blood transfusion and rebalanced hemostasis and the selection of anticoagulant drugs during thrombosis, in order to provide a theoretical basis and new ideas for solving related issues in clinical practice.

ABSTRACT

This review aims to update and discuss the main challenges in controlling emergent and reemergent forms of Trypanosoma cruzi transmission through organ transplantation, blood products and vertical transmission in endemic and non-endemic areas as well as emergent forms of transmission in endemic countries through contaminated food, currently representing the major cause of acute illness in several countries. As a neglected tropical disease potentially controllable with a major impact on morbimortality and socioeconomic aspects, Chagas disease (CD) was approved at the WHO global plan to interrupt four transmission routes by 2030 (vector/blood transfusion/organ transplant/congenital). Implementation of universal or target screening for CD are highly recommended in blood banks of non-endemic regions; in organ transplants donors in endemic/non-endemic areas as well as in women at risk from endemic areas (reproductive age women/pregnant women-respective babies). Moreover, main challenges for surveillance are the application of molecular methods for identification of infected babies, donor transmitted infection and of live parasites in the food. In addition, the systematic recording of acute/non-acute cases and transmission sources is crucial to establish databases for control and surveillance purposes. Remarkably, antiparasitic treatment of infected reproductive age women and infected babies is essential for the elimination of congenital CD by 2030.

ABSTRACT

ABSTRACT Introduction: Tranexamic acid is widely used for patients undergoing total knee arthroplasty (TKA). However, the duration of systemic tranexamic acid (TXA) administration varies in many reports. Hence, this study aims to compare blood loss between a single intravenous (IV) TXA dose, and one dose of IV TXA combined with oral TXA, during 48-hour postoperative care in primary TKA. Methods: Ninety-four patients with primary osteoarthritis, who underwent primary TKA, were randomized into two groups. The first group consisted of 47 patients and received a dose of 750 mg IV TXA and 750 mg oral TXA postoperatively at 8-hour intervals for 48 hours. In the second group, 47 patients received a single dose of IV TXA and a placebo at the same intervals for the same time duration. Hemoglobin (Hb) was measured at 4, 24 and 72 hours after operation. Results: The mean total blood loss were not different between the two groups (p=0.37). There was no difference in total Hb reduction or closed suction drainage outputs (p=0.9 and 0.07, respectively). Conclusion: The extended use of oral TXA for 48-hour postoperative care did not decrease the total blood loss following TKA compared with a single dose of IV TXA. Level Of Evidence I; High quality randomized trial .


RESUMO Introdução: O ácido tranexâmico é amplamente utilizado para pacientes submetidos à artroplastia total do joelho (ATJ). No entanto, a duração da administração de ácido tranexâmico sistêmico (ATS) varia em muitos relatórios. Assim, este estudo tem como objetivo comparar a perda sanguínea entre uma dose única intravenosa (IV) de ATS e uma dose de ATS IV combinada com ATS oral, no atendimento pós-operatório ao longo de 48 horas em ATJ primária. Métodos: Noventa e quatro pacientes com osteoartrite primária, submetidos a ATJ primária, foram randomizados em dois grupos. O primeiro grupo de 47 pacientes recebeu uma dose de 750 mg de ATS IV e 750 mg de ATS oral no pós-operatório, a cada 8 horas, durante 48 horas. No segundo grupo, 47 pacientes receberam dose única de ATS IV e placebo nos mesmos intervalos e pelo mesmo período de tempo. A hemoglobina (Hb) foi medida às 4, 24 e 72 horas de pós-operatório. Resultados: A média da perda sanguínea total não foi diferente entre os dois grupos (p = 0,37). Não houve diferença na redução da hemoglobina total ou saídas de drenagem de sucção fechada (p = 0,9 e 0,07, respectivamente). Conclusão: O uso prolongado de ácido tranexâmico oral por 48 horas de pós-operatório não diminuiu a perda total de sangue após ATJ em comparação com uma dose única de ATS IV. Nível de Evidência I; Estudo Clínico randomizado de alta qualidade .

ABSTRACT

Introducción. La resucitación hemostática es una estrategia para compensar la pérdida sanguínea y disminuir el impacto de la coagulación inducida por trauma. Debido a que la disponibilidad de transfundir una razón equilibrada de hemocomponentes es difícil de lograr en el entorno clínico, la sangre total ha reaparecido como una estrategia fisiológica, con ventajas logísticas, que le permiten ser accesible para iniciar tempranamente la resucitación hemostática. El objetivo de este estudio fue evaluar las propiedades celulares, coagulantes y viscoelásticas de la sangre total almacenada por 21 días. Métodos. Las unidades de sangre total fueron obtenidas de 20 donantes voluntarios sanos. Se procesaron mediante un sistema de leucorreducción ahorrador de plaquetas y fueron almacenadas en refrigeración (1-6°C) sin agitación. Se analizaron los días 0, 6, 11 y 21. Las bolsas fueron analizadas para evaluar las líneas celulares, niveles de factores de coagulación y propiedades viscoelásticas mediante tromboelastografía. Resultados. El conteo eritrocitario y la hemoglobina se mantuvieron estables. El conteo de plaquetas tuvo una reducción del 50 % al sexto día, pero se mantuvo estable el resto del seguimiento. Los factores de coagulación II-V-VII-X, fibrinógeno y proteína C se mantuvieron dentro del rango normal. La tromboelastografía mostró una prolongación en el tiempo del inicio de la formación del coágulo, pero sin alterar la formación final de un coágulo estable. Conclusiones. La sangre total leucorreducida y con filtro ahorrador de plaquetas conserva sus propiedades hemostáticas por 21 días. Este es el primer paso en Colombia para la evaluación clínica de esta opción, que permita hacer una realidad universal la resucitación hemostática del paciente con trauma severo.


Background. Hemostatic resuscitation is a strategy to compensate blood loss and reduce the impact of trauma-induced coagulopathy. However, balanced resuscitation presents challenges in its application in the clinical setting. Whole blood has re-emerged as a physiologic strategy with logistical advantages that offer the opportunity for early initiation of hemostatic resuscitation. The study aims to evaluate the cellular, coagulation, and viscoelastic properties of whole blood preserved for 21 days. Methods. Whole blood units were donated by 20 healthy volunteers. These units were processed using a platelet-sparing leukoreduction filtration system. Units were stored under refrigeration (1-6°C) without agitation and were sampled on days 0, 6, 11, 16, and 21. The units were tested to assess its cellular properties and coagulation factors levels. In addition, viscoelastic features were tested using tromboelastography.Results. Red blood cells count and hemoglobin levels remained stables. Platelet count had a 50% reduction on day 6, and then remained stable for 21 days. Factors II-V-VII-X, fibrinogen, and protein C remained within normal range. Tromboelastrography test showed that the reaction time of clot formation is prolonged, but the final clot formation is not altered. Conclusion. Whole blood retains its hemostatic properties for 21 days. This is the first step to evaluate the use of whole blood in the resuscitation protocols for Colombia allowing hemostatic resuscitation become a universal reality.

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.
