General guidelines regarding any invasive procedure on an anticoagulated patient or patient with
known clotting abnormality (eg arthrogram, biopsy, drainage, myelogram, lumbar puncture):
INR
PLATELETS
PTT
INR should be 1.5 or less. Ordering
physician to alter therapy to achieve this goal.
If unable to get INR 1.5 or less, procedure must be
approved by radiologist. If patient not on Coumadin,
value can be up to 10 days old.
Plt must be greater 90,000. Ordering physician to
alter therapy to achieve this goal. Value can be up to
10 days unless recent instability. If recent instability,
Plt must be re-drawn within 3-7 days of procedure.
PTT should be less than 35. Value can be up to 10
days old unless patient is on Heparin. If on Heparin,
follow Heparin protocol.
Radiologist must be notified of all abnormal labs
Following medication guidelines:
Coumadin
INR should be 1.5 or less. Ordering Physician
to alter therapy to achieve this goal
