Caudal block

What is a caudal block?

A caudal block is an injection of medicine near the lower spine to decrease pain after lower abdominal or groin-area surgery.

What can I expect after the caudal block?

Your child may not have a full return of normal sensation in the lower body for 4 to 6 hours after the caudal block.

Generally, muscle strength is not affected, but lack of normal sensation may make the child wobbly. It is unsafe to walk until normal sensation returns.

It is normal for children to feel the need to urinate. They may wet their pants as the caudal block wears off.

How should I care for my child?

Until normal sensation returns, avoid having your child walk alone. Help your child walk until steady.

Watch your child closely and keep sharp and hot objects away until normal sensation returns.

Give your child acetaminophen (Tylenol® or another brand) or other prescribed pain medicine before the caudal block wears off.

When should I call the doctor?

  • not urinating at least every 8 hours
  • discomfort not relieved by acetaminophen or prescribed medicine
