Retrospective analysis of the incidence of epidural haematoma in patients with epidural catheters and abnormal coagulation parameters

摘要

Background. Epidural haematoma is a rare but potentially catastrophic complication associated with epidural catheterization. The times of insertion and removal of epidural catheters are high-risk periods for epidural haematoma formation, especially with abnormal coagulation parameters. There is a lack of data on the incidence of epidural haematoma in patients with abnormal coagulation parameters.
