Safety of mini-dose heparin administration for neurosurgical patients

Abstract

✓ A course of small doses of heparin given subcutaneously before and after elective operations has been reported to reduce the incidence of deep venous thrombosis and pulmonary embolism in general surgical patients. To test the safety of mini-dose heparin for neurosurgical patients, mini-dose heparin was used for 150 adult patients undergoing elective neurosurgical procedures. No operative complications were thought to be related to heparin administration. Postoperatively, there were four wound seromas, two hematomas, and one non-fatal pulmonary embolus. Seven patients died postoperatively, of whom five had no evidence of pulmonary embolus. Although no conclusions were drawn as to the effectiveness of mini-dose heparin in preventing deep venous thrombosis or pulmonary emboli, it was believed that the method could be used safely and without fear of increased intracranial or intraspinal bleeding for neurosurgical patients.
