Fresh frozen plasma-learning objective: chose the appropriate therapy for a patient suffering from severe warfarin overdose. answer: e the symptoms of the patient strongly suggest a hemorrhagic complication of warfarin therapy. the standard treatment of warfarin overdose would be vit k but the patient is diaphoretic and hypotensive suggesting that bleeding is life-threatening. in this case the action of vit k is too slow to be useful (onset is delayed for 6 hours and is complete by 24 hours). fresh frozen plasma (which contains prothrombin, factor vii, ix and x) or activated clotting factors should be administered in case of severe acute bleeding due to anticoagulant therapy. a) (see explanation above) b, c, d) these drug are either useless, or dangerous, in bleeding disorders.
