Abstract
Introduction/Description: For accessing the cervical epidural space, the contralateral oblique (CLO) view under fluoroscopy at 50 degrees (CLO50) has been described as a safe and effective view for obtaining epidural access with some studies suggesting it is superior to the lateral and anteroposterior (AP) views for correct needle tip placement [1]. Because false loss of resistance can still occur using this approach, contrast medium needs to be injected prior to medication administration to ensure correct placement. It is important to recognize spread patterns within the meningeal layers to distinguish between proper placement into the epidural space and unintended spread into the subdural or intrathecal space.
