ABSTRACT

Objetivo: examinar el efecto de la técnica de tos de mediana intensidad durante la inyección subcutánea de heparina de bajo peso molecular sobre la severidad del dolor y la satisfacción individual en pacientes de cirugía general. Método: estudio prospectivo, cuasi experimental, que incluyó a 100 pacientes a los que se les prescribió una inyección subcutánea de heparina de bajo peso molecular una vez cada 24 horas. Cada paciente recibió dos inyecciones por el mismo investigador utilizando técnica de inyección estándar con técnica de tos de intensidad media y solo técnica de inyección estándar. Resultados: hubo una diferencia estadísticamente significativa entre las puntuaciones medias de los pacientes sobre la intensidad del dolor y los niveles de satisfacción después de las inyecciones administradas por las dos técnicas (p= 0,000). Además, se encontró que el género afectó la severidad del dolor relacionado con la inyección, pero no afectó el nivel de satisfacción individual. Conclusión: se encontró que la técnica de tos de intensidad media reduce la severidad del dolor y aumenta la satisfacción del paciente de cirugía general que reciben inyecciones subcutáneas de heparina de bajo peso molecular. Registro del ensayo: NCT05681338.


Objective: to examine the effect of the medium intensity coughing technique during subcutaneous low molecular weight heparin injection on pain severity and individual satisfaction in general surgery patients. Method: the prospective, quasi-experimental study included 100 patients who had been prescribed a subcutaneous low molecular weight heparin injection once in 24 hours. Each patient received two injections by the same researcher, one using the standard injection technique with medium intensity coughing technique and the other only the standard injection technique. Results: there was a statistically significant difference between patients' mean scores on pain severity and satisfaction levels after injections administered by the two techniques (p= 0.000). Also, it was found that gender affected pain severity relating to the injection but did not affect the level of individual satisfaction. Conclusion: the medium intensity coughing technique was found to reduce pain severity and increase patient satisfaction in general surgery patients receiving subcutaneous low molecular weight heparin injections. Trial registration: NCT05681338.


Objetivo: examinar o efeito da técnica de tosse de média intensidade durante injeção subcutânea de heparina de baixo peso molecular na intensidade da dor e satisfação individual em pacientes submetidos à cirurgia geral. Método: estudo prospetivo, quasi experimental que incluiu 100 pacientes que haviam recebido uma injeção subcutânea de heparina de baixo peso molecular em 24 horas. Cada paciente recebeu duas injeções pelo mesmo pesquisador usando a técnica de injeção padrão com técnica de tosse de média intensidade e apenas técnica de injeção padrão. Resultados: houve diferença estatisticamente significativa entre as pontuações médias dos pacientes quanto à gravidade da dor e níveis de satisfação após as injeções administradas pelas duas técnicas (p = 0,000). Além disso, verificou-se que o sexo do paciente afetou a intensidade da dor relacionada à injeção, mas não afetou o nível de satisfação individual. Conclusão: a técnica de tosse de média intensidade reduz a intensidade da dor e aumenta a satisfação de pacientes submetidos à cirurgia geral recebendo injeções subcutâneas de heparina de baixo peso molecular. Registro do ensaio clínico: NCT05681338.

ABSTRACT

Abstract Introduction Cancer-associated thrombosis is a leading cause of morbidity and mortality in malignancy patients. Prophylactic anticoagulation is under-utilized and the cost of low-molecular-weight heparin (LMWH) and direct oral anticoagulants is a major barrier in developing countries. Material and methods A retrospective analysis was performed of all cancer-associated thrombosis patients attending the thrombosis clinic at a tertiary-level referral hospital based in North India between 2011 and 2015. Patient demographics and disease-related parameters were collected and analyzed. Results A total of 771 patients attended the thrombosis clinic during study period, of which 64 cases were malignancy-associated. Of these, 56% of the patients were female and 20% were bedridden. The median age was 48.5 years, adenocarcinoma (48%) being the most common histological subtype. Gynecological malignancies (30%) were the most common malignancies, followed by genitourinary (11%) malignancies. Most of the cases occurred during first year of diagnosis (51%), and only 14% occurred after 3 years. Most of the patients were on combined treatment. Almost 40% of the patients developed thrombosis within 30 days of surgical treatment. Lower limb thrombosis was the most commonly seen type (56%), while abdominal and pulmonary thrombosis were both seen in 5%. Patients were managed with LMWH and vitamin K antagonists (84.3%) and only 6.25% with LMWH alone. Direct oral anticoagulants were not commonly used during the study period. Discussion At the hospital studied, most of the cases occurred early in the disease course. Postoperative prophylaxis could have contributed towards reducing thrombosis in the peri-operative period. Early suspicion and prompt treatment can improve quality of life in such patients.

ABSTRACT

Blood compatibility is the main restriction of blood-contacting medical devices in clinical application, especially long-term blood-contacting medical devices will stimulate the immune defense mechanism of the host, resulting in thrombosis. Heparin anticoagulant coating links heparin molecules to the surface of medical device product materials, improves the compatibility between the material surface interface and the body, and reduces the host immune defense reactions. This study reviews the structure and biological properties of heparin, the market application status of heparin-coated medical products, the insufficiency and improvement of heparin coating, which can provide a reference for the application research of blood contact medical devices.

ABSTRACT

A heparina é a solução mais utilizada para selar cateteres de hemodiálise. Entretanto, seu uso está associado a complicações locais e sistêmicas. A solução de citrato surge como alternativa devido aos seus efeitos anticoagulantes. O objetivo desta revisão sistemática é avaliar o risco de infecção da corrente sanguínea relacionada ao cateter usando heparina em comparação com solução de bloqueio de citrato. Esta revisão sistemática seguiu o protocolo Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) e a estratégia Population, Intervention, Comparison, Outcome (PICO), bem como utilizou as bases de dados Medline, Lilacs e Scielo. Buscaram-se ensaios clínicos randomizados que comparassem heparina com citrato como solução de bloqueio associada à infecção de corrente sanguínea relacionada a cateter. Inicialmente, foram encontrados 1.204 artigos. Após a leitura de seus títulos e resumos, foram selecionados 33 estudos. Depois da aplicação dos critérios de exclusão, restaram quatro artigos. Destes, o desfecho primário foi infecção da corrente sanguínea relacionada ao cateter. Em Weijmer et al. houve redução no grupo citrato. Por outro lado, Barcellos et al. mostraram resultados opostos usando o modelo multivariado. Power et al. não identificaram diferença entre os grupos e Winnett et al. favoreceram o grupo citrato usando análise de subgrupo. Não foi possível determinar diferença entre o grupo citrato e heparina na redução da infecção da corrente sanguínea relacionada ao cateter. São necessários mais estudos utilizando uma população maior e solução padronizada de citrato ou heparina.


As the most used solution to seal hemodialysis catheters, heparin use is associated with local and systemic complications. Citrate solution emerges as an alternative due to its anticoagulant effects. This systematic review sought to evaluate the risk of catheter-related bloodstream infection using heparin compared to citrate lock solution. Based on the PRISMA protocol and PICO strategy, data were collected from the Medline, Lilacs and Scielo databases. The search strategy included randomized clinical trials that compared heparin versus citrate as lock solution associated with catheter-related bloodstream infection. Of the 1,204 articles identified, 33 were selected after reading tittles and abstract. After applying the exclusion criteria, four papers were included for review. Primary outcome was catheter-related bloodstream infection. Weijmer et al. observed a reduction in the citrate group. In turn, Barcellos et al. showed opposite results using a multivariate model. Power et al. found no difference between groups and Winnet et al. favored the citrate group using subgroup analysis. Results on the difference between citrate versus heparin in reducing catheter-related bloodstream infection were inconclusive. Further studies using a bigger population and standardized citrate or heparin solution are needed.

Método: estudo experimental delineado para análise de potencial hidrogeniônico e concentração por cromatografia líquida de alta eficiência de soluções de cloridrato de vancomicina (n=06) e cloridrato de vancomicina e heparina sódica (n=06). Submeteram-se as soluções estudadas à ausência de luz, 22°C e 37°C. Análises em triplicadas (n=192) ocorreram no momento inicial (T0), três (T3), oito (T8) e 24 horas (T24) após preparo. Os dados foram submetidos à análise de variância (p≤0,05). Resultados: a concentração do antimicrobiano a 22°C apresentou redução (T0-T8) e posterior elevação (T24); o potencial hidrogeniônico diminuiu significativamente ao longo do tempo. Em 37°C a concentração aumentou em até T3 e reduziu em T24, com redução de potencial hidrogeniônico até 24 horas. A concentração das soluções de cloridrato de vancomicina e heparina sódica apresentaram variação com redução a 22°C acompanhada de aumento de potencial hidrogeniônico. Observou-se formação de precipitado por inspeção visual da associação cloridrato de vancomicina e heparina sódica (T3). Conclusão: evidenciou-se estabilidade farmacológica do cloridrato de vancomicina (5 mg/mL) e incompatibilidade física com heparina sódica (100 UI/mL) após três horas de associação nas soluções de selo antimicrobiano estudadas.


Abstract Objective: to verify the stability of vancomycin hydrochloride in antimicrobial seal solutions with and without association of heparin sodium according to temperature and association time. Method: an experimental study designed for the analysis of hydrogenionic potential and concentration by means of high-efficiency liquid chromatography of vancomycin hydrochloride (n=06) and vancomycin hydrochloride and heparin sodium (n=06). The solutions studied were submitted to absence of light, as well as to 22°C and 37°C. Analyses in triplicate (n=192) were performed at the initial moment (T0) and three (T3), eight (T8) and 24 hours (T24) after preparation. The data were submitted to analysis of variance (p≤0.05). Results: concentration of the antimicrobial at 22°C presented a reduction (T0-T8) and a subsequent increase (T24); hydrogenionic potential decreased significantly over time. At 37°C, the concentration increased up to T3 and decreased at T24, with a reduction of hydrogenionic potential up to 24 hours. Concentration of the vancomycin hydrochloride and heparin sodium solutions varied with a reduction at 22°C, accompanied by increased hydrogenionic potential. Precipitate formation was observed by visual inspection of the vancomycin hydrochloride-heparin sodium association (T3). Conclusion: pharmacological stability of vancomycin hydrochloride (5 mg/mL) and physical incompatibility with heparin sodium (100 IU/mL) were evidenced after three hours of association in the antimicrobial seal solutions studied.

ABSTRACT

OBJECTIVES@#Heparin is mainly used as an anticoagulant in clinic, and it also has a certain anti-inflammatory effect. At present, after portal vein islet transplantation in diabetic patients, heparin is mainly infused through the peripheral veins of the limbs to achieve the purpose of anticoagulation and protection of the graft, rather than through the portal vein. In this study, animal experiments were conducted to investigate the effect of heparin infusion via the portal vein and marginal ear vein on the instant blood-mediated inflammatory reaction (IBMIR) after portal vein islet transplantation, which is the choice of anticoagulation methods for clinical islet transplantation to provide a basis for decision-making.@*METHODS@#A total of 50 neonatal pigs (Xeno-1 type, 3-5 days) were selected. Islets were isolated and purified from the pancreas of neonatal pigs. Ten non-diabetic Landrace pigs (1.5-2.0 months) served as recipients, and 12 000 IEQ/kg neonatal porcine islets were transplanted into the liver through the portal vein. All recipients received bolus injection of 50 U/kg of heparin 10 minutes before transplantation. After the bolus injection of heparin, the experimental group received heparin via the portal vein [10 U/(kg·h), 5 recipients], and the control group received heparin via the marginal ear vein [10 U/(kg·h), 5 recipients]. The superior vena cava blood was collected from the 2 groups pre-operation at 1, 3, 24 h post-operation of the transplantation. The portal vein blood was collected from the experimental group at 1 and 3 h after the transplantation as well. The levels of complement C3a, C5a, thrombin-antithrombin complex (TAT), β-thromboglobulin (β-TG), and D-dimer as well as activated partial thromboplastin time (APTT) in superior vena cava blood from 1 and 3 h post-transplantation were detected in the 2 groups, and the levels of anti-Xa and anti-IIa in the portal vein and superior vena cava blood from 1 and 3 h post-transplantation in the experimental group were detected. Twenty four hours after the transplantation, the liver tissues in the 2 groups were collected for pathological examination to observe the inflammatory cell infiltration and peripheral thrombosis around the islets graft in liver.@*RESULTS@#Before transplantation, there was no statistically significant difference in C3a, C5a, TAT, β-TG, D-dimer levels and APTT between the 2 groups (all P>0.05). At 1 and 3 h after transplantation, the C3a, TAT, and D-dimer levels in the experimental group were significant decreased than those in the control groups (all P<0.05), and at 3 h after transplantation the C5a was significant decreased than that in the control group (P<0.05). At 1 and 3 h after transplantation, the anti-Xa and anti-IIa levels in the portal vein blood were significantly increased than those in the superior vena cava blood in the experimental group (all P<0.05). Pathological results showed the presence of islet cell clusters in the liver blood vessels. The thrombus formation and neutrophil infiltration around islet graft was not obvious in the experimental group, while massive thrombus formation and neutrophil infiltration in the control group.@*CONCLUSIONS@#Compared with marginal ear vein infusion of heparin, the direct infusion of heparin in the portal vein has a certain inhibitory effect on complement system, coagulation system activation and inflammatory cell infiltration in portal vein islet transplantation, which may attenuate the occurrence of IBMIR.

We report a 47-year-old male with a severe disease caused by COVID-19, who required mechanical ventilation for 18 ays. During the hospital stay he received dexamethasone and anticoagulation with heparin. After discharge a new chest CT scan showed homogeneous hypo vascular enlargement of both adrenal glands, not present in the initial imaging studies. It was interpreted as a subacute bilateral adrenal hemorrhage. The patient remained stable and without any complaint.

ABSTRACT

ABSTRACT Introduction: The clinical impact of vascular calcification is well established in the context of cardiovascular morbidity and mortality, but other clinical syndromes, such as calciphylaxis, although less frequent, have a significant impact on chronic kidney disease. Methods: Case report of a 27-year-old woman, who had complained of bilateral pain in her toes for 3 days, with the presence of small necrotic areas in the referred sites. She had a history of type 1 diabetes (25 years ago), with chronic kidney disease, on peritoneal dialysis, in addition to rheumatoid arthritis. She was admitted to the hospital, which preceded the current condition, due to exacerbation of rheumatoid arthritis, evolving with intracardiac thrombus due to venous catheter complications, when she started using warfarin. Ischemia progressed to her feet, causing the need for bilateral amputations. Her chirodactyls were also affected. Thrombophilia, vasculitis, endocarditis or other embolic sources were investigated and discarded. Her pathology report evidenced skin necrosis and superficial soft parts with recent arterial thrombosis, and Monckeberg's medial calcification. We started treatment with bisphosphonate and sodium thiosulfate, conversion to hemodialysis and replacement of warfarin with unfractionated heparin. Despite all the therapy, the patient died after four months of evolution. Discussion: Calciphylaxis is a rare microvasculature calcification syndrome that results in severe ischemic injuries. It has pathogenesis related to the mineral and bone disorder of chronic kidney disease combined with the imbalance between promoters and inhibitors of vascular calcification, with particular importance to vitamin K antagonism. Conclusion: The preventive strategy is fundamental, since the therapy is complex with poorly validated effectiveness.


RESUMO Introdução: O impacto clínico da calcificação vascular está bem estabelecido no âmbito de morbimortalidade cardiovascular, mas outras síndromes clínicas, como a calcifilaxia, apesar de menos frequente, têm significante impacto na doença renal crônica. Métodos: Relato de caso de mulher, 27 anos, com queixa de dor em pododáctilos bilateralmente havia 3 dias, com presença de pequenas áreas necróticas nos locais referidos. Antecedente pessoal de diabetes tipo 1 (há 25 anos), com doença renal crônica, em diálise peritoneal, além de artrite reumatoide. Teve internação hospitalar, que antecedeu o quadro atual, devido à exacerbação da artrite reumatoide, evoluindo com trombo intracardíaco por complicação de cateter venoso, quando iniciou uso de varfarina. A isquemia progrediu para pés com necessidade de amputações bilaterais. Quirodáctilos também foram acometidos. Trombofilias, vasculites, endocardite ou outras fontes emboligênicas foram pesquisadas e descartadas. Anatomopatológico evidenciou: necrose de pele e partes moles superficiais com trombose arterial recente e calcificação medial de Monckeberg. Tratamento foi instituído com bisfosfonato e tiossulfato de sódio, conversão para hemodiálise e substituição de varfarina por heparina não fracionada. Apesar de toda a terapia, a paciente foi a óbito após quatro meses de evolução. Discussão: A calcifilaxia é uma rara síndrome de calcificação da microvasculatura que resulta em graves lesões isquêmicas. Tem patogênese relacionada ao distúrbio mineral e ósseo da doença renal crônica combinado com o desbalanço entre promotores e inibidores de calcificação vascular, com particular importância ao antagonismo da vitamina K. Conclusão: A estratégia preventiva é fundamental, uma vez que a terapia é complexa e de eficácia pouco validada.

ABSTRACT

Resumen La flegmasia cerulea dolens es una complicación rara y poco frecuente de la trombosis venos a profunda. Los principales factores predisponentes son los procesos neoformativos, estados de hiper coagulabilidad, insuficiencia cardíaca congestiva, embarazo, inmovilización prolongada y cirugías. Se caracteriza por edema masivo, dolor intenso y cianosis. Sin tratamiento evoluciona con isquemia, necrosis y amputación del miembro comprometido. No existe consenso en su tratamiento, pero éste debe ser rápido, multidisciplinario y agresivo. La anticoagulación con heparina, la fibrinólisis sistémica, la trombectomía percutánea con fibrinólisis local, la trombectomía quirúrgica, la fasciotomía, la colocación de filtro de vena cava inferior y la amputación son algunos de los tratamientos propuestos.


Abstract Phlegmasia cerulea dolens (FCD) is a rare complication of deep vein thrombosis. Its cause is unknown. The main predisposing factors for the disease are neoformative processes, hypercoagulable states, congestive heart failure, pregnancy, prolonged immobilization, and surgeries on the affected limb. FCD is characterized by massive edema, severe pain, and cyanosis. The diagnosis is clinical. It is associated in most cases with pulmonary embolism and can lead to loss of the compromised limb if not treated in time. So far there is no consensus on its treatment. In clinical practice the use of anticoagulation with heparin, local thrombolysis, systemic fibrinolysis, surgical thrombectomy, fasciotomy, and inferior vena cava filter are described. In irreversible cases amputation is required. We present the case of a patient with FCD, the treatment performed and the evolution.

ABSTRACT

ABSTRACT Objective: Intraoperative blood salvage (cell saver technique) in cardiac surgery is universally used in surgical procedures with a marked risk of blood loss. The primary objectives of this study were to determine the concentration of residual heparin in the final product that is reinfused into the patient in the operating room and to evaluate the efficacy and safety of the cell saver technique. Method: Twelve patients undergoing elective cardiac surgery were enrolled in this study. Using the XTRA Autotransfusion System, blood samples were collected from the cardiotomy reservoir, both prior to blood processing (pre-sample) and after it, directly from the bag with processed product (post-sample). Hematocrit and hemoglobin levels, the protein, albumin and residual heparin concentrations, hemolysis index, and the platelet, erythrocyte and leukocyte counts were measured. Results: Hematocrit and hemoglobin levels and red blood cell counts were higher in post-processing samples, with a mean variation of 54.78%, 19.81 g/dl and 6.84 × 106/mm3, respectively (p < 0.001). The mean hematocrit of the processed bag was 63.49 g/dl (range: 57.2-67.5). The residual heparin levels were ≤0.1 IU/ml in all post-treatment analyses (p = 0.003). No related adverse events were observed. Conclusion: The reduced residual heparin values (≤0.1 IU/ml) in processed blood found in this study are extremely important, as they are consistent with the American Association of Blood Banks guidelines, which establish target values below 0.5 IU/ml. The procedure was effective, safe and compliant with legal requirements and the available international literature.

ABSTRACT

La pandemia COVID-19 provocada por el betacoronavirus SARS-CoV-2 exige rápidas respuestas desde el campo de la medicina. El riesgo de tromboembolismo venoso y arterial está aumentado durante la infección, especialmente en pacientes críticos. En ese contexto se destaca una coagulopatía caracterizada por niveles elevados de dímero D, con tendencia a la falla multiorgánica, y aumento de la mortalidad. Esas anormalidades de la hemostasia responden a varios mecanismos que deben tenerse en cuenta para la toma de decisiones terapéuticas. Analizamos la evidencia científica disponible en la que se fundamenta el enfoque terapéutico de la coagulopatía descripta y sus complicaciones, con el objetivo de diseñar recomendaciones terapéuticas realistas tendientes a disminuir la morbilidad y la mortalidad en pacientes con COVID-19


The coronavirus disease 2019 (COVID-19) pandemic requires rapid medical responses. The risk of venous and arterial thromboembolism increases in critically ill patients with SARS-CoV-2 infection. There is a hypercoagulable state that includes elevated levels of D-dimer, with an increased risk of organ failure and increased mortality. The abnormalities described in hemostasis should be considered for therapeutic decision making. We analyzed the available scientific evidence for the therapeutic approach of coagulopathy in the course of the disease with the objective of designing realistic therapeutic recommendations aimed at reducing morbidity and mortality in patients with COVID-19

ABSTRACT

Objective: to evaluate the effectiveness of the 50 IU/mL heparin solution compared to the 0.9% isotonic saline solution in preventing occlusion of the double lumen Hickman® catheter, 7 and 9 French, in patients undergoing hematopoietic stem cell transplantation. Method: a triple-blind randomized clinical trial. 17 double-lumen catheters (heparin group: n=7 and 0.9% isotonic saline group: n=10) were analyzed in which the two catheter routes were evaluated separately, totaling 34 lumens. The outcome variables were occlusion without reflux and complete occlusion. Descriptive analyses were performed using the Chi-square test and, of survival, according to the Kaplan-Meier test. Results: the mean number of days until the occlusion outcome was 52 in the heparin group and 13.46 in the 0.9% isotonic saline group in the white catheter route (p<0.001). In the red route, the mean follow-up days in the heparin group were 35.29, with no occlusion and 22.30 in the 0.9% isotonic saline group until the first occlusion (p=0.030). Conclusion: blocking with 50 IU/mL heparin solution is more effective than 0.9% isotonic saline in preventing occlusion of the Hickman® catheter. Brazilian Registry of Clinical Trials: RBR-3ht499.

ABSTRACT

Abstract Introduction: Heparin-induced thrombocytopenia (HIT) is a potentially lethal complication of unfractionated or low-molecular weight heparin therapy. We aimed to determine the incidence and mortality rate of patients with positive heparin/platelet factor 4 (PF4) antibodies, which is a rapid detection test of HIT. Methods: Coronary artery bypass grafting and mitral and aortic valve surgeries were evaluated. Cardiopulmonary bypass was employed in all patients. The diagnosis of HIT was based on immunological assays. Postoperative complications, mortality rates, and the causes of death were specified in patients with positive heparin/PF4 antibodies. Results: Postoperative thrombocytopenia was detected in 257 patients. Twenty of these patients undergoing open heart surgery were included in the final analysis. Antibodies against heparin/PF4 complex were positive in 20 patients. The mean body mass index was 28.8±2.3 kg/m2, mean value of left ventricular ejection fraction was 48.3±6.7%, cardiopulmonary bypass time was 113.0±35.0 min, aortic cross-clamping time was 88.0±32.7 min, mean intensive care unit length of stay was 10.9±4.9 days, mean preoperative platelet count was 307.250±88528 platelets/microliter, and mean postoperative platelet count was 243.050±89.354 platelets/microliter. The mean duration of heparin exposure was 6.9±2.9 days. The mortality rate was 45% (nine patients) and 1.2% (three patients) in heparin/PF4 complex positive and negative patients, respectively. Conclusion: Although the incidence of HIT was low in patients undergoing open heart surgery, an increased rate of early mortality was observed in patients with positive heparin/PF4 antibodies.

ABSTRACT

Abstract Objective: To compare immediate postoperative results in patients receiving heparin-albumin-coated and non-coated circuits. Methods: A total of 241 patients undergoing on-pump cardiac surgery were divided into two groups: those receiving heparin-coated circuits (Bioline®, Maquet Cardiopulmonary AG., Hirrlingen, Germany) and those receiving non-coated circuits (Maquet Cardiopulmonary AG., Hirrlingen, Germany). Results: Activated clotting times (ACT) during cardiopulmonary bypass (CPB) were significantly shorter in the heparin-albumin-coated group than in the non-coated group (355.64±34.12 vs. 560.38±90.20, respectively, P=0.001). In-hospital mortality and postoperative stroke rates and lengths of intensive care unit stay were similar between the groups; in contrast, in the heparin-albumin-coated group, patients had significantly better outcomes for hospital stay, drainage, and need for erythrocyte transfusion. Conclusion: Heparin-coated circuits and reduced level of systemic heparinization with 300 seconds of target ACT level in cardiac surgery under CPB are safe and result in a very satisfactory clinical course.
