 PATIENT CARE: Bridging is commonly used for perioperative anticoagulation. In patients who have atrial fibrillation or a history of blood clotting, warfarin, which has a relatively long half-life, is withheld several days before surgery. The bridge consists of the administration of low-molecular-weight heparins (LMWHs), which have a shorter half-life, until about 12 hr before the procedure in order to prevent clotting. At a safe time after the operation, LMWHs are reinstituted until warfarin reaches therapeutic levels, e.g., an international normalized ratio of 2 or more.
