What is an epidural?
An epidural is an injection that aims to numb down the lower half of your body to provide pain relief and adequate conditions for surgery.
It is named after the space where the local anaesthetic drugs are injected to achieve this effect – the epidural space, which is a tiny, almost non-existent space that sits just outside of your spine. An epidural is therefore done by “feel”, that is: advancing a needle attached to a pressurised syringe – when pressure is lost, it indicates that the needle has found this tiny space. Expert technique and patient cooperation is therefore very important at a successful epidural insertion.
