Coagulopathy induced by viperid snake venoms in a murine model: Comparison of standard coagulation tests and rotational thromboelastometry.

Viperid snakebite envenoming is often characterized by a venom-induced consumption coagulopathy due to the procoagulant effect of venom components, resulting in the alteration of clotting laboratory tests. There is a growing trend to use rotational thromboelastometry in the assessment of clotting disturbances in a variety of pathologies, although its use in experimental models of envenoming has been limited. An in vivo murine model was implemented to assess the coagulopathy induced by three Central American viperid venoms which have different mechanisms of action on clotting factors, i.
