An epidural block is a commonly used form of regional anesthesia for labor and birth. We insert a needle into the epidural space, which is just outside your spinal canal. Through this needle we insert a small, hollow, plastic tube called a catheter. The needle is then removed. The catheter stays in your back for your entire labor and until after the birth of your baby. Through the catheter we give medications continuously to help keep you comfortable, numbing a narrow area of your lower abdomen. If needed, the block may be extended to include your perineum.
