Pediatric Multichannel Intraluminal Impedance (MII)

A MII test consists of a catheter placement into the nose leading to the esophagus with PH monitoring. This PH monitoring has been proven to be a valuable tool for diagnosing gastro esophageal reflux and associated symptoms in infants and children. There are a number of symptoms that originate in the esophagus including heartburn, difficulty swallowing food or liquid, and chest pain. MII will allow the doctor to treat problems of reflux and plan the proper care for your child.

Prior to Your Child's MII Checklist

Prior to your child's day in Endoscopy, please discuss with your child's doctor the following:

  • Any medical preparation your child may need before their procedure
  • The scheduled procedure time and date, as well as, the time you'll need to arrive at the hospital on the day of the procedure
  • Please have your child stop eating and drinking (including water, gum and mints) 8 hours prior to the test, unless instructed differently by the doctor
  • What care your child will need at home after their procedure
  • If your child becomes sick or you need to cancel your child's procedure, please call Dr. Khaled's office at (309)672-4200 or UnityPoint Health - Methodist | Proctor at (309)672-5768

Day of MII Checklist

What to bring with you on the day of your child's procedure:

  • When you arrive at UnityPoint Health Methodist please check in at the patient registration desk located on the first floor of UnityPoint Health Methodist.
  • Please arrive at the patient registration area on time. Every effort is made by the doctor and medical staff to start the procedure on time. However, procedures may be delayed due to emergencies or other unforeseen circumstances. You will be kept informed regarding any delays.
  • Please bring your child's favorite security object from home (pacifier, toy, blanket, or hand held game)
  • Your child's preferred empty bottle, sippy cup or sports bottle for a drink in recovery after the procedure.
  • Insurance card, ID, paperwork, etc.
  • Medication Information - Names and doses and time of day taken
  • Guardianship papers, if applicable
  • Please dress your child in comfortable clothes
  • Please do not allow your child to take any medications unless instructed/approved by the doctor

MII Procedure

  • Inform the Endoscopy nurse of the three main symptoms that your child is experiencing to program into the PH monitor (Note: not all children have three)
  • The nurse will calibrate the probe to your child's PH. To do this, an electrode will be placed on your child's chest which will stay on until the next day. Then the child will place their finger with the probe into two different colored PH solutions.
  • After the patient is calibrated, the PH probe will be placed. Once the probe is placed, it will be taped to the nose, one side of cheek, and behind the ear.
  • Following placement of the MII your child will need an x-ray to confirm the correct placement of the probe. Sometimes the probe will need to be adjusted.
  • The child may also have on arm splints on both arms/elbows after the probe is placed to remind the child/parents to be extra careful with the probe and not to accidentally pull on the probe
  • Sometimes children are admitted after the probe is placed; instructions will still be given to the child's parents/responsible adult.

Following the MII

  • Discharge instructions will be provided by the Endoscopy department following procedure. Verbal and written instructions will be given. At the bottom of the written instructions will be the time to return to Endoscopy to have the probe removed the next day.
  • Your child should return 24hours after the PH probe is placed to Endoscopy.
  • You will not need to register in admitting when coming back to get probe removed. You will just need to go to the 3rd floor to the Endoscopy Department
  • The probe removal will take approximately 5-10mintues then your child will be able to go home.
  • If the probe moves from the marked line given, call UnityPoint Health - Methodist immediately and the nurse will instruct you what to do 309-672-5768
  • The probe needs to remain in the nose approximately 24 hours. If the probe is removed before that time the test may be invalid.

If you have any additional questions or concerns please don't hesitate to call Dr. Khaled's office between 8:00 a.m. and 4 p.m. Monday - Friday at 309-672-4200; or you can call UnityPoint Health - Methodist Endoscopy between 7:30 a.m. and 4 p.m. Monday - Friday at 309-672-5768.

We look forward to meeting you and your child!
