Epidural needles (such as the Tuohy needle) are larger, hollow needles that enter the epidural space. The curve of the needle is designed to enable an inserted cannula to be threaded into the epidural space at an angle. Once the cannula is in place the epidural needle is removed. Anaesthesia and analgesia can be administered via the epidural.. Most epidurals used on pregnant women are 8 cm (3.15 in) long. The gauge size can range from 14 gauge to 25 gauge, although most doctors use either 16, 17, or 18 gauge needles for pregnant women. Larger patients may require longer epidural needles (source: Association of Anaesthetists). In this article, we'll look a bit more in-depth into why.
