I was wondering what are the differences between a pregnancy epidural and a lower back epidural?

Different meds: Epidural anesthesia during labor uses a small catheter placed into the epidural space to infuse anesthetic agents. An epidural steroid injection for low back pain is a single injection, using a needle, of a long-acting steroid into the epidural space.

Anesthetic/Steroid: The main difference is that labor epidural uses mostly anesthetics to relieve labor pains and low back epidural is to relieve pain with use of steroid type medication. Also a labor epidural uses higher amt of volume of anesthetic than a low back epidural. There are 3 types of low back epidurals and x-ray guidance is used: interlaminar, transforaminal and caudal. Labor epidural does not use xray.
