Abstract
Anticoagulation and profound thrombocytopenia are among the few absolute contraindications to regional anesthesia (1,2). The risk of epidural hematoma is well documented as a rare complication in fully anticoagulated patients given spinal or epidural anesthesia (1,3–6). The issue of the relative safety of regional anesthesia in patients on "minidose" heparin remains unsettled. Should surgery be necessary in an anticoagulated patient, general anesthesia is considered a safer option.
Unfortunately for the patient who is suffering from intractable pain of malignant origin and who is also receiving anticoagulants, the options of techniques for pain relief other than regional anesthesia are more limited.
We report on 37 patients that were fully anticoagulated and 19 patients with profound thrombocytopenia suffering from intractable pain of malignant origin who underwent 336 caudal blocks with morphine sulfate and bupivacaine for pain control, and we review the safety of this approach.
