Learning About Peripheral Nerve Blocks in Children

What is a peripheral nerve block?

A peripheral nerve block is a shot of numbing medicine near a specific nerve or group of nerves. It can be used to numb a part of the body (often an arm or a leg) for a procedure or surgery. It can also help with pain afterward.

What are some common types of peripheral nerve blocks?

Some common types of peripheral nerve blocks include brachial plexus, femoral, and popliteal blocks. A brachial plexus block numbs the shoulder, arm, and hand. A femoral block numbs most of the leg. A popliteal block numbs most of the lower leg and foot.

How is it done?

Your child will get medicine to help them relax, feel sleepy, or go to sleep.

The doctor may use ultrasound or another way to help guide the shot for the nerve block.

After finding the right spot for the block, the doctor numbs the skin. Then they put the nerve block near the nerves. If your child is awake, they may feel some pressure in the area. But they should not feel pain.

How do you prepare?

You'll get instructions to help you prepare. They'll tell you what to expect at the hospital. They'll also tell you when your child should stop eating, drinking, or breastfeeding. And you'll learn what medicines they can and can't take. If your child feels nervous, ask your doctor about ways to help them relax.

What should you tell the anesthesia specialist before the procedure?

Tell the provider about any health problems your child has. Tell them about your child's past surgeries. Also let them know if a family member had problems with anesthesia. Give them a list of any medicines, vitamins, supplements, and herbal remedies your child takes.

What are the risks?

Problems after a nerve block are rare. There is a small risk of nerve damage, infection, or bleeding where the numbing medicine was given.
