Learning About Caudal Blocks for Children

Regions of the spine

What is a caudal block?

A caudal block is a shot of numbing medicine. A doctor may use it to numb the area for some surgeries below the belly button. It may also be used to help keep your child as pain-free as possible in the first few hours after surgery.

A caudal block is usually combined with sedation or general anesthesia. Those medicines make your child feel relaxed or fall asleep during surgery.

How is a caudal block done?

The injection goes into the lower part of your child's back. It enters into the epidural space near the nerves at the end of the tailbone. The block numbs those nerves so your child won't feel pain. This is done after your child is asleep.

What can you expect after your child's caudal block?

The caudal block may affect how well your child can move their legs. Follow your doctor's instructions to keep your child safe until the block wears off. That usually takes 3 to 6 hours.

Problems from a nerve block are rare. There is a small risk of problems like bleeding, damage to nerves, and infection.

Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if your child is having problems. It's also a good idea to know your child's test results and keep a list of the medicines your child takes.
