When Your Child Needs a Barium Enema

Have your child drink only clear liquids 24 hours before the exam.

Give your child a laxative, a suppository, or enema the night before and on the day of the exam, as instructed by your healthcare provider.

Don’t give your child anything to eat or drink 4 to 6 hours before the exam.

Talk with your healthcare provider if any medicines need to be given during this time. 

Has allergies to medicines

Has allergies to iodinated contrast material

Has any health problems

Has had surgery

Is pregnant or may be pregnant

Is taking any medicines

You can stay with your child in the X-ray room. You’ll be given a lead apron to wear for your safety. Pregnant women aren’t allowed in the X-ray room.

Your child lies on an X-ray table.

Movement affects the quality of the results. If your child can’t stay still during the exam, they may be held down. In rare cases, your child is sedated or given anesthesia (medicines to make your child relax or sleep). The healthcare provider will tell you more about this if needed.

The technologist first takes an X-ray of your child’s belly (abdomen).

Then your child lies on their side as the radiologist or technologist puts the tip of an enema tube into the rectum. Barium flows through this tube and fills the colon. Tape may be used to keep the enema tube in place. Air may also be injected through the tube.

Live X-ray images (fluoroscopy) are viewed on a screen as the barium moves through your child’s colon.

Your child may need to roll over, shift positions, or take deep breaths and hold them while X-rays are taken.

Once the enema tube is removed, your child can go to the bathroom if needed.

The radiologist may take final X-rays of your child’s empty colon before the exam is done.

Your child may need to return to the hospital the next day for more X-rays. This often happens if your child doesn’t have a bowel movement at the end of the exam.

Unless told not to, your child can return to their normal routine and diet right away. But make sure your child drinks plenty of water. Water helps relieve constipation that may occur after the exam.

Your child’s stool may look chalky white or light for 1 to 2 days due to the barium. If no barium is passed in 24 hours, call the healthcare provider.

The radiologist may discuss early results with you after the exam. A report is given to your child’s healthcare provider, who follows up with full results.

Explain that the radiologist will be testing the colon and rectum. Use brief and simple terms to describe the exam. Younger children have shorter attention spans, so do this shortly before the exam. Older children can be given more time to understand the exam in advance. 

As best you can, describe how the exam will feel. There may be some cramping and mild pain. Your child may also feel the urge to use the bathroom during the exam.

Let your child ask questions.

Use play when helpful. This can include role-playing with a child’s favorite toy or object. It may help older children to see pictures of what happens during the exam. 

Allergic reaction (such as hives, itching, or wheezing) to barium

Constipation and bowel obstruction due to barium that hasn't left the body

Tear in the colon wall (rare)

Radiation exposure from X-rays

Reaction (such as headaches, shivering, and vomiting) to sedative or anesthesia
