Spinal anaesthesia and the use of anticoagulants

Best Pract Res Clin Anaesthesiol. 2003 Sep;17(3):443-9. doi: 10.1016/s1521-6896(02)00091-5.

Abstract

This chapter addresses the increasing incidence of spinal haematoma after central neuraxis anaesthesia in patients receiving drugs that affect coagulation. Administration of low-molecular-weight heparins in the perioperative period is highlighted because these drugs remain the 'gold standard' for prophylaxis against deep-vein thrombosis. The performance of spinal anaesthesia in patients already receiving antiplatelet drugs is discussed--as well as special warnings in such a setting. In addition, issues such as those concerning the administration of unfractionated heparin, anti-vitamin K drugs or new antiplatelet and antithrombotic medications are addressed. Finally, specific recommendations regarding each class of drug are defined in order to avoid the occurrence of a rare but catastrophic event such as spinal haematoma.
