Epidural block

Epidural block is a type of anesthesia that numbs a large region of the body, typically for procedures in the lower body such as childbirth or surgery on the legs. It is administered via an injection into the epidural space, which is located outside the dura mater (the outermost, toughest, and most fibrous of the three membranes covering the brain and spinal cord).

Procedure

The procedure for an epidural block involves the insertion of a needle and a small tube (catheter) into the epidural space. The needle is removed, leaving the catheter in place to provide medication either continuously or intermittently.

Uses

Epidural blocks are commonly used in childbirth to reduce the mother's pain. They are also used in surgeries of the lower body and legs, and to manage chronic pain conditions.

Risks and Complications

While epidural blocks are generally safe, they do carry some risks. These can include a drop in blood pressure, headache, infection, bleeding around the area of the spine, difficulty urinating, and, rarely, nerve damage.
