ABSTRACT
Los test viscoelásticos son tecnologías diseñadas para estudiar la dinámica de formación del coágulo, identificar coagulopatías en tiempo real, realizar un diagnóstico y guiar el tratamiento hemostático de forma específica. Sus principales aplicaciones son el tratamiento de la hemorragia significativa en cualquier escenario, así como el de otras situaciones que cursen con alteraciones clínicamente relevantes de la hemostasia, como la coagulopatía del paciente crítico. Su uso se establece mediante algoritmos basados en la evidencia científica que están sujetos a variabilidad en función del contexto clínico. Basada en una encuesta distribuida en varios hospitales, esta revisión objetiva el grado de extensión y la homogeneidad en el uso de los test viscoelásticos en nuestro medio en cirugía cardiaca, en el trasplante hepático y en el paciente politraumatizado. Los resultados obtenidos revelan disparidad en aspectos clave que van desde su capacidad diagnóstica propiamente dicha hasta la interpretación de los parámetros básicos. Estos hallazgos permiten plantear potenciales áreas de investigación con el objetivo de mejorar su rendimiento.(AU)
Viscoelastic tests are designed to study the dynamics of clot formation, identify coagulopathies in real time, arrive at a diagnosis, and guide patient-specific administration of haemostatics. They are mainly used to treat clinically significant bleeding in any setting, and are also used in other situations involving clinically relevant alterations in haemostasis, such as coagulopathy in critically ill patients. These tests are administered following evidence-based algorithms that vary depending on the clinical context. This review summarises the results of a survey conducted in several hospitals to determine the prevalence and standardisation of viscoelastic tests in cardiac surgery, liver transplantation, and multiple trauma patients in Spain. The results reveal divergent opinions on key aspects, ranging from the diagnostic capacity of these tests to the interpretation of the basic parameters. On the basis of these findings, we propose a number of potential areas in which further research will improve the performance of these tests.(AU)
