Today we welcome one of the gurus in anti-coagulant reversal, John J. Lewin. Dr. Lewin recently published one of the recent landmark articles in the field of Neurocritical care: "Guideline for Reversal of Antithrombotics in Intracranial Hemorrhage". Today he is gracious enough to spend 60 minutes with us, and not a second can be missed if you EVER expect to take care of a patient with a head bleed on AC!!
