MicKey button tube insertion procedure (3000)

Key points below

What do I need to know before I place a MIC-Key button?

If your child still has their very first tube, and it was never changed before, then do not change the button. Your doctor or nurse will tell you when the first tube change will happen.

If your child’s tube has been changed and you were shown how to change it, then you can change it yourself. Change the button every 3 to 6 months. Sometimes the button needs to be changed sooner if it fails.

See the Caring for a Child with a Feeding Tube Notebook or go to www.childrenswi.org/gtube. This has a video on how to change the button. You can also use the manual that came in the button kit.
If you were never shown how to change a button, talk with your child’s nurse or doctor.

What problems may I have when replacing the button?

Problem: Button fell out



Problem: The button will not go back in

Causes: Opening in skin may have started to shrink.


Problem: Balloon will not deflate

Causes: Balloon port clogged.

Solution: Gently twist the slip tip syringe in the balloon port until the valve is opened. Using a moist cotton-tipped applicator, clean out the balloon port. Attach a syringe and try again. Call the clinic to talk to the nurse or doctor if this does not work. If this is your child’s first tube, you should not check water balloon.

Problem: The button needs changing and no spare button at home
