A local anaesthesia in which anaesthetic is injected into the space between the vertebral canal and the dura mater.
Epidural anaesthesia is a pain relief technique where a local anaesthetic is introduced into the epidural space. This space surrounds the protective membranes of the spinal cord, located in the middle and lower back. This method effectively numbs the nerves that cater to the chest and lower body. It is commonly employed to manage pain during and post-surgery, and is also frequently used during labor and delivery.
