250 mg vial administered as 1.0 mg/kg intravenous (IV) bolus and 2.5 mg/kg/h IV infusion during the procedure with the option to administer additional 0.1 to 0.5 mg/kg boluses to increase the level of anticoagulation as clinically indicated. A low-dose infusion could have been administered in the preoperative phase (up to 48 hours before the procedure) and in the postoperative phase (up to 14 days after the procedure) as clinically indicated for management of HIT/TS. A starting bolus of 0.1 mg/kg and/or an infusion of 0.2 mg/kg/h titrated to a desired activated partial thromboplastin time (aPTT), eg, 1.5-2.5 times baseline aPTT, was recommended.
