Low Profile Button Tubes

Low Profile ButtonLow Profile Balloon Tube (MIC-KEY Button or AMT Mini-ONE Button)

This is a skin level tube with a balloon inside the stomach. Additional extension tubing can be attached to the button to give feedings, medications and to vent the stomach if needed.


Caring for the Low Profile/Button Type G-Tube and Site

Cleaning the Site

  1. Wash your hands with soap and water before touching the G-tube site.
  2. Use warm soapy water on a Q-tip to clean around the G-tube once a day (more often if needed).
    (May use ½ strength hydrogen peroxide instead if there is crusting around the tube that is difficult to remove with soap and water or if it is becoming reddened around the tube. If using ½ strength hydrogen peroxide be sure to rinse with plain water after cleansing.)
  3. Pat dry.
  4. After 2 weeks from original tube placement/surgery, may have regular baths (submerge in water)
  5. Do not use heavily scented soaps or cleansers.
  6. Do not apply ointments or medications to the area unless instructed by your healthcare provider


  • Keep a split gauze or button buddy around the tube at all times
    (Button buddy may be used 1 week after surgery)
  • Change it daily or when it becomes soiled/moist
  • Be sure to turn the tube in the tract at least once daily (about ¼ of a turn)

Securing the Tube

White Grip-Lok securement device (with and without extension tubing attached)




Extension tubing

Movement and pulling on the G-tube site should be minimized to prevent trauma and leakage.

  • You should always use some sort of securement device, such as a Grip-Lok or Cinch, or medical tape, such as Micropore (paper tape) or Hypafix, or a to secure the extension tubing whenever using the tube for feedings (continuous or bolus/intermittent).
  • Always remove the extension tubing whenever you are not using the tube for feeding/giving medication AND whenever you move your child from bed to chair, etc.
  • Onesies, one-piece sleepers, overalls, or other one-piece clothing will help keep the G-tube from being pulled out.
  • Stretchy gauze/netting used to cover abdomen
  • ACE bandage: May be used similar to an abdominal binder for younger children/infants. If using ACE wrap, cut it in half lengthwise and be sure not to pull it tightly around the abdomen or it will compress the G-tube into your child’s skin
  • Abdominal binder: may be used for older children/adolescents
  • Use a “tape tag” and safety pin to pin the tube to your child’s clothing to prevent accidental pulling at the G-tube site. (If using, be careful when undressing your child. You MUST remove the safety pin first!)

Bathing and Swimming

  • May swim in a chlorinated pool 2 weeks after surgery as long as the exit site well healed
  • May swim in a lake/ocean 2 months after surgery


  • Your child may not participate in strenuous activities (contact sports, gym class, playground equipment, etc) for 1 month. After 1 month, your child may participate in strenuous activities if they keep the G-tube covered/secured (minimally for the first 3 months) to prevent dislodgement. After 3 months, your child should remain mindful of the G-tube, but an abdominal binder/cover is not required.
  • Tummy time is okay for young infants. Your child may sleep or spend time on his/her belly. Make sure the G-tube is taped securely.
  • If your child does physical therapy/occupational therapy, they may resume 2 weeks after surgery. Until then they may do exercises that do not place them on their belly or use core muscles.

  6. Gently pull back on the plunger to get the air out of the child’s stomach.  
  7. Formula may come back into the syringe during venting, be sure to give any formula that backs up in the syringe back to the child taking care not to push in any air.
