 Heparin Drip Calculation Reference  (sample calculations for reference only!)    Heparin Infusion Rate:  Total Units (in IV bag) = Units/hour                                             Total Volume (ml)         X (ml/hour)    Your patient has a DVT is ordered for a heparin infusion to start at 18 units/kg/hour  per the practitioner’s order.  His weight is 75kg.  The heparin infusion comes in a  500ml bag with 25,000 units.  Calculate the starting rate of the infusion (ml/hour).    Step 1:  Calculate the starting units per hour .          18 units X 75 kg = 1350 units/hour    Step 2:  Calculate the starting rate of the Infusion (solve for X).               Heparin Infusion Rate:  25,000 units =  1350 units/hour                                                      500ml                 X (ml/hour)                                                            25,000 units (X ml/hr) = 675,000            X ml/hr = 675,000                 25,000         X  =  27  ml/hour    Your patient’s PTT result is 55.  Per the Intravenous High Intensity Heparin  Nomogram (for DVT/PE), the infusion dose should be increased by 2 units/kg/hour.   Your patient is currently receiving an infusion based on 18/units/kg/hour.  What is the  new rate for the infusion (note:  use the same initial weight to calculate the new rate).    Step 1:  Calculate the new units per hour.          18 units/kg/hour + 2 units/kg/hour = 20 units/kg/hour          20units X 75 kg = 1500 units/hour    Step 2:  Calculate the new rate of the infusion (solve for X).            Heparin Infusion Rate:  25,000 units = 1500 units/hour                                                     500ml                 X (ml/hour)                                                            25,000 units (X ml/hr) = 750,000            X ml/hr = 750,000                 25,000         X  =  30  ml/hour  Поделитесь с Вашими друзьями:
