Coagulación y sangrado masivo: nuevos conceptos fisiopatológicos
Contenido principal del artículo
Resumen
Actualmente se acepta de forma categórica que el evento iniciador principal de la coagulación sanguínea es la exposición del factor tisular (FT), lo cual da lugar a la formación del complejo factor VIIa/FT que activa a los factores IX y X en la superficie de las células que expresan el FT y, por último, la producción de trombina. A continuación se revisarán los aspectos relacionados con la nueva teoría celular que trata de explicar de una forma más fisiológica todos los eventos que ocurren durante la coagulación y al final se tocarán algunos aspectos relacionados con los trastornos de la coagulación en el paciente traumatizado.
