Meniscus Sign: A Test for the Confirmation of Correct Placement of Epidural Catheter.
Localization of epidural space has no clear-cut end point like during subarachnoid block, making it an enigma to the anaesthetist. Confirmation of correct placement of the catheter is desirable in order to prevent failure, high or total spinal when large amount of local anaesthetic agent is inadvertently injected in the intrathecal space, subdural block and lastly local anaesthesia systemic toxicity. This study evaluated the use of meniscus sign to confirm correct placement of epidural catheter. ⋯ The meniscus sign is a reliable indicator of correct epidural catheter placement, with high sensitivity and specificity.
