SUMMARY
1. Coagulopathy: epidural hematoma risk is rather low (1 in 70,000 to 1 in 190,000)[1][2]. However, severe morbidity such as paraparesis or quadriparesis can be associated with an epidural hematoma.
2. NSAIDs: including aspirin, reduce platelet aggregation, but have not been implicated in increased bleeding risk or complications in lumbar epidural injections[3].
3. Antiplatelet medication: based on labeling precautions, surgical literature, and interventional cardiology and radiology data, it is recommended clopidogrel be discontinued for 7 days and ticlopidine for 14 days before spinal intervention[4][5].
4. Anticoagulants: warfarin is contraindication for spinal interventions & should be discontinued for 4-5 days before any spinal intervention to allow the PT and INR to normalize. Prophylactic LMWH shoulde be withheld for 12 hrs prior to procedure & and can be immediately recommenced after. Theraputic LMWH should be withheld for 24 hrs prior and 24 hrs after.
5. Prophylactic low-dose unfractionated heparin is not a contraindication for spinal procedures[6]. Therapeutic heparin should be discontinued 2-4 hrs before any spinal procedure and a normal APTT documented before; can be recommenced 1 hr after the procedure[7].
