Spinal, epidural, and caudal anesthesia are used to block pain from an entire area of the body. They're often used for surgeries on the belly, legs, groin or genitals.
For spinal anesthesia, a single shot of medicine is given near the spinal cord. For epidural anesthesia, medicine is usually given through a small tube (catheter) that's inserted into the epidural space near the spinal cord. This tube is left in place so that more medicine can be given as needed. Caudal anesthesia is medicine put into the lower part of your child's back in the epidural space near the nerves at the end of the tailbone. Sometimes a catheter is also used.
Sometimes both spinal and epidural medicines are used. Spinal medicine offers quick pain relief. Then the epidural medicine can offer relief for longer.
Side effects can include a headache or nausea. There may be soreness at the injection site on the back. Serious side effects, such as nerve damage, are rare.
