What to buy with G Tube Extension Set

How to measure Mic-Key Stoma length?

Selection of the correct size MIC-KEY is critical for the safety and comfort of the patient. Measure the length of the patient’s stoma with the Stoma Measuring Device. The shaft length of the MIC-KEY selected should be the same as the length of the stoma. An inappropriately sized MIC-KEY can cause necrosis, buried bumper syndrome, and/or hyper granulation tissue.

  1. Lubricate the tip of the Stoma Measuring Device with water-soluble lubricant. Caution: Do not use mineral oil. Do not use petroleum jelly. 
  2. Advance the Stoma Measuring Device over the guidewire, through the stoma, and into the stomach. Caution: Do not use force. 
  3. Fill the Luer slip syringe with 5 ml of water and attach to the balloon valve. Depress the syringe plunger and inflate the balloon. 
  4. Gently pull the device toward the abdomen until the balloon rests against the inside of the stomach wall. 
  5. Slide the plastic disc down to the abdomen and record the measurement above the disc. 
  6. Add 4–5 mm to the recorded measurement to ensure the proper stoma length and fit in any position. Record the measurement. 
  7. Using a Luer slip syringe, remove the water in the balloon. 
  8. Remove the stoma measuring device. 
  9. Document the date, lot number, and measured centimeter shaft length
