Modified Barium Swallow
What you should know
A modified barium swallow (MBS) is an x-ray procedure used to examine problems with swallowing. Liquid barium is a white, chalky solution that helps caregivers see the pictures more clearly. Barium is mixed with liquids and foods to show how they are swallowed. This helps caregivers decide what liquids or foods are safe for you to eat. MBS may also detect if food or liquids go into your airways.
Care AgreementYou have the right to help plan your care. Learn about your health condition and how it may be treated. Discuss treatment options with your caregivers to decide what care you want to receive. You always have the right to refuse treatment.
- You may have abdominal cramps, vomiting, or problems swallowing. The barium may become hard and cause a blockage in your bowels. Your esophagus may tear. The barium may leak out of this tear or go down your airway. If the barium goes down your airway, it can block oxygen from your heart and brain. This can be life-threatening.
- Without this procedure, your condition may not be diagnosed. Correct treatment may not be given. Your signs and symptoms may get worse. You may have trouble eating, digesting food, and having a bowel movement.
The week before your procedure:
- Write down the correct date, time, and location of your procedure.
- Arrange a ride home. Ask a family member or friend to drive you home after your surgery or procedure. Do not drive yourself home.
- Ask your caregiver if you need to stop using aspirin or any other prescribed or over-the-counter medicine before your procedure or surgery.
- Bring your medicine bottles or a list of your medicines when you see your caregiver. Tell your caregiver if you are allergic to any medicine. Tell your caregiver if you use any herbs, food supplements, or over-the-counter medicine.
- Tell the caregiver if you have ever had an allergic reaction to contrast solution.
- You may need blood, urine, or bowel movement tests before your procedure. You may also need a chest x-ray. Talk to your caregiver about these or other tests you may need. Write down the date, time, and location for each test.
The day before your procedure:
Ask your caregiver about directions for eating and drinking. You may need to drink clear liquids, such as gelatin, broth, or clear fruit juice.
The day of your procedure:
- Do not eat or drink anything on the morning of your procedure. The pictures may not be seen clearly if your esophagus and stomach are not empty.
- Ask your caregiver before taking any medicine on the day of your procedure. These medicines include insulin, diabetic pills, high blood pressure pills, or heart pills. Bring a list of all the medicines you take, or your pill bottles, with you to the hospital.
- You or a close family member will be asked to sign a legal document called a consent form. It gives caregivers permission to do the procedure or surgery. It also explains the problems that may happen, and your choices. Make sure all your questions are answered before you sign this form.
- Caregivers may insert an intravenous tube (IV) into your vein. A vein in the arm is usually chosen. Through the IV tube, you may be given liquids and medicine.
- An anesthesiologist will talk to you before your surgery. You may need medicine to keep you asleep or numb an area of your body during surgery. Tell caregivers if you or anyone in your family has had a problem with anesthesia in the past.
What will happen:
- Your caregiver will give you medicine that will help relax your esophagus and prevent spasms. Caregivers will take x-rays while you stand, before you drink the barium. You will then be given barium mixtures to drink. Caregivers will ask you to sit up, stand still, and move your neck and head as pictures are taken. You will also need to talk, swallow, and change head positions as you drink the mixtures.
- If you are able to swallow liquids without any problems, foods will then be tested. These foods will have different thickness or textures. You may be given barium-coated puddings and cookies, or barium tablets to swallow. Pictures will be taken to see how food goes down your throat, esophagus, and into your stomach. When the procedure is finished, you will have to drink extra liquids. This helps flush barium from your body. More pictures may be taken after the barium has been flushed out.
After your procedure:
You will be taken to a room to rest until you are fully awake. Caregivers will monitor you closely for any problems. Do not get out of bed until your caregiver says it is okay. When your caregiver sees that you are okay, you will be able to go home or be taken to your hospital room.
Contact a caregiver if
- You cannot make it to your procedure.
- You have a fever.
- You get a cold or the flu.
- You have questions or concerns about your procedure.
Seek Care Immediately if
- Your symptoms get worse.
