[Caution for prophylaxis of thrombosis in connection with spinal anesthesia. Risk of hemorrhage when low-molecular-weight heparin is administered in epidural/spinal anesthesia].
There is an increasing awareness of the risk of haematoma in patients anticoagulated with low molecular weight heparins and scheduled to undergo epidural or spinal anaesthesia. The mechanisms causing this are not always clear, the incidence is very low. Risk factors are discussed as well as possible precautions to avoid this iatrogenic complication.
