Begin infusion of heparin at 13 units/kg/h (25,000 units/250 mL = 100 units/mL). Obtain partial thromboplastin time (PTT) every 6 hours and adjust the infusion using the following scale: Convert the patient’s weight from pounds to kilograms. PTT Heparin Dosing <35 Bolus 70 units/kg and increase drip by 4 units/kg/h 35-54 Bolus 35 units/kg and increase drip by 3 units/kg/h 55-85 Therapeutic—no change 86-100 Decrease drip by 2 units/kg/h >100 Hold infusion 1 hour, decrease drip by 3 units/kg/h, then restart aston or neparin 515 units/kg/h (25,000 units/250 mL = 100 units/mL). Obtain partial thromboplastin time (PTT) every 6 hours and ad following scale: Hold infusion 1 hour, decrease drip by 3 units/kg/h, Convert the patient’s weight from pounds to kilograms.
