Abstract
El término hemostasia significa prevención de la pérdida de sangre. La sangre, es el tejido líquido formado por plasma sanguíneo y células (glóbulos rojos, glóbulos blancos y plaquetas). Para mantener la hemostasia, en circunstancias normales, existe un perfecto equilibrio entre coagulación y fibrinólisis. La pérdida del equilibrio entre estos mecanismos, da lugar a la aparición de diversos cuadros patológicos que se engloban como: diátesis trombótica, cuando predomina la actividad hemostática, o diátesis hemorrágica, cuando la actividad coagulante está disminuida. La diátesis hemorrágica, puede producirse por un déficit de factores de la coagulación, o por una disminución de su actividad, o bien porque exista una estimulación de la actividad fibrinolítica. La coagulación tiene como objetivo principal la formación de trombina y fibrina que estabilicen el coágulo. A este nivel, pueden actuar tanto fármacos antihemorrágicos que favorecen la coagulación, como agentes anticoagulantes que mantienen la fluidez...
The term hemostasis means prevention of blood loss.To maintain hemostasis, normally, there is a perfect balance between coagulation and fibrinolysis. The loss of balance between these mechanisms can result in pathological conditions, such as: thrombotic diathesis or hemorrhagic diathesis. Hemorrhagic diathesis can be due to a lack of coagulation factors, or to a decrease in their activity, or to a stimulation of the fibrinolytic activity. Coagulation’s main goal is the synthesis of thrombin and fibrin to stabilize the clot. Antihemorrhagic drugs, that stimulate coagulation, and anticoagulant agents, that maintain fluidity, can act at this level.Vitamin K antagonist (VKA) drugs are indicated for the treatment and prophylaxis of thromboembolic conditions. For the follow-up of these treatments, the international normalized ratio (INR) is monitored. In general, INR levels between 2 and 3 are considered adequate. In patients with oral anticoagulant therapy (OAT) with these drugs, the main adverse reaction is bleeding...
