Transcribed Image Text:A blood sample taken from a 247 lb patient 6 hours after heparin therapy is initiated shows an aPTT of 32 seconds. Calculate the
infusion rate, in mL/hr, according to the heparin protocol below.
|Standard Heparin IV Premixed Solution is 25,000 units in 250 mL (100 units per mL)
Initial laboratory tests (draw before starting heparin): APTT, PT, CBC with platelet count
Day 2 and every 3 days thereafter: CBC with platelet count
APTT six (6) hours after heparin infusion is started
Bolus Dose
None
80 units/kg (limit 8000 units)
ADULT WEIGHT-BASED HEPARIN PROTOCOL-
units)
Other (specify:
Continuous infusion rate APTT six (6) hours after every change in heparin administration rate or bolus dose of heparin
Once a therapeutic aPTT level is reached, do an aPTT six (6) hours later
18 units/kg/h After two (2) consecutive therapeutic aPTT levels are obtained, do an aPTT daily at 0600
Discontinue all IM medications and other IM injections
Other (specify:"
units/h)
APTT Value
Heparin Dose Adjustments
<35 seconds
Bolus with 80 units/kg and increase infusion rate by 4 units/kg/h
35 to 45 seconds
Bolus with 80 units/kg and increase infusion rate by 2 units/kg/h
46 to 70 seconds
No change in infusion rate
71 to 90 seconds
Decrease infusion rate by 2 units/kg/h
Hold infusion for 1 hour; when restarted, decrease infusion rate
by 3 units/kg/h
>90 seconds
