HOW TO CHANGE OR REPLACE MIC-KEY TUBE

What is a Mic-key tube and how do you change it?

A Mic-key button is a gastrostomy tube that rests against the skin, and is held inside the stomach by a balloon on the inside inflated with sterile water. It can easily be changed at home by a parent.

Equipment

  • Mic-key tube
  • 5 ml syringe empty
  • 5 ml syringe with sterile water
  • Water-soluble lubricant
  • Washcloth

Procedure to change Mic-Key tube

  1. Wash Hands
  2. Draw up 5 mls of sterile or distilled water into your 5 ml syringe.
  3. Remove the new MIC-KEY*feeding tube from the package. Fill the balloon with 5 ml sterile or distilled water.
  4. Remove the syringe and observe the balloon. It should be symmetrical. Check for leaks. Remove the water from the balloon.
  5. Attach a 5 ml luer slip syringe to the balloon valve of the old MIC-KEY* feeding tube. Pull back on the plunger until all the water is out of the balloon.
  6. Gently remove the MIC-KEY* feeding tube from your child’s stomach. It may help to use a little water-soluble lubricant as you are removing it.
  7. Lubricate the tip of the new MIC-KEY* feeding tube with a watersoluble agent. DO NOT USE OIL OR PETROLEUM JELLY.
  8. Gently guide the new tube into the stoma. Insert the tube all the way until it is flat against the skin.
