In the past decades, the most common anticoagulation agent was vitamin-K antagonist, who plays an important role in surgery with bleeding risk. The disadvantages of vitamin-K antagonist include narrow therapeutic window, interactions with drugs and foods, and not dose dependent drug for every patient. So these patients need regular blood test for monitoring the concentration of drugs to avoid the bleeding risk. In recent years, a novel oral anticoagulation agent was developed for preventing stroke of non-valvular atrial fibrilliation and for the deep vein thrombosis patients. The benefit is no need of regular blood test. When patient use anticoagulation agent, this will have effect for the surgery including the bleeding risk in the oral and maxillofacial surgery inpatient and outpatient. We will focus on the novel anticoagulation agent with reviewing literatures about the pharmacotherapeutics and treatment policy of surgery, and the emergency treatment of bleeding with suggestions.
