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 Other (specify: units) 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 After two (2) consecutive therapeutic aPTT levels are obtained, do an aPTT daily at 0600 Discontinue all IM medications and other IM injections 18 units/kg/h 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 >90 seconds Hold infusion for 1 hour; when restarted, decrease infusion rate by 3 units/ka/h

Transcribed Image Text:A blood sample taken from a 247 Ib 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-
Other (specify:
units)
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
After two (2) consecutive therapeutic aPTT levels are obtained, do an aPTT daily at 0600
Discontinue all IM medications and other IM injections
18 units/kg/h
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
>90 seconds
Hold infusion for 1 hour; when restarted, decrease infusion rate
by 3 units/kg/h
