Abstract
Severe hemorrhage with necessity of allogeneic blood transfusion is common complication in intensive care unit and is associated with increased morbidity and mortality. Prompt recognition and treatment of bleeding causes becomes essential for the effective control of hemorrhage, rationalizing the use of allogeneic blood components, and in this way, preventing an occurrence of their potential adverse effects. Conventional coagulation tests such as prothrombin time and activated partial thromboplastin time present limitations in predicting bleeding and guiding transfusion therapy in critically ill patients. Viscoelastic tests such as thromboelastography and rotational thromboelastometry allow rapid detection of coagulopathy and goal-directed therapy with specific hemostatic drugs. The new era of thromboelastometry relies on its efficacy, practicality, reproducibility and cost-effectiveness to establish itself as the main diagnostic tool and transfusion guide in patients with severe active bleeding. RESUMO A hemorragia grave com necessidade de transfusão de sangue e componentes é uma complicação frequente na unidade de terapia intensiva e está associada ao aumento da morbidade e da mortalidade. A identificação adequada e o tratamento precoce da causa específica da coagulopatia tornam-se fundamentais para o controle efetivo da hemorragia, racionalizando a utilização de sangue e componentes, e desta forma, prevenindo a ocorrência de efeitos adversos. Testes convencionais da coagulação (tempo de ativação de protrombina e tempo de tromboplastina parcial ativada) apresentam limitações para prever sangramento e guiar a terapia transfusional em pacientes graves. Testes viscoelásticos como a tromboelastografia e tromboelastometria rotacional permitem a rápida detecção da coagulopatia e orientam a terapia de forma individualizada, alvo dirigida com drogas hemostáticas específicas. A nova era da tromboelastometria confia na sua eficácia, praticidade, reprodutibilidade e custo-eficácia para se firmar como a principal ferramenta diagnóstica e guia transfusional em pacientes com sangramento ativo grave.
This research output has an Altmetric Attention Score of 4. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 01 October 2024.
All research outputs
#7,962,193
of 25,382,440 outputs
Outputs from Einstein (São Paulo)
#94
of 576 outputs
Outputs of similar age
#118,313
of 331,880 outputs
Outputs of similar age from Einstein (São Paulo)
#1
of 3 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. This one has received more attention than most of these and is in the 67th percentile.
So far Altmetric has tracked 576 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.0. This one has done well, scoring higher than 83% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 331,880 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 63% of its contemporaries.
We're also able to compare this research output to 3 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
