MIC* Gastrostomy Feeding Tube
The first of its kind, the MIC* Gastrostomy Feeding Tube is indicated for patients requiring continuous enteral feeding.
Q: What is the purpose of the syringes?
A 6 ml slip tip syringe is included with the feeding tube. It
should be used to fill and empty the retention balloon when
periodic volume checks are made and when the feeding tube is
replaced. The 35 ml catheter tip syringe should be used when
priming and flushing the extension sets and when checking for
proper placement of the feeding tube.
Q: What are the steps for daily maintenance of the feeding tube?
Q: What maintenance is required for the silicone balloon?
The balloon should be filled with water at the time of
insertion. We recommend the use of distilled or sterile water as
saline may crystallize and clog the balloon valve or lumen and air
may seep out and cause the balloon to collapse. Tap water may
contain harmful contaminants that could shorten the life of the
balloon. The balloon volume should be checked weekly and additional
water added if the amount in the balloon is less than the amount
prescribed by the physician. The balloon should never be filled
with air as it may leak and the tube may fall out of the
Q: How is the silicone feeding tube retention balloon filled and emptied?
The feeding tube balloon, which holds the tube in place, is
located inside the stomach. It is filled and emptied with water by
inserting a slip tip syringe into the balloon valve. The valve
should only be used to check the balloon volume or to replace the
tube. Never feed through the balloon valve.
Q: What if the balloon leaks or ruptures?
Silicone balloons may last several months, but the life span of
the balloon can be affected by various factors such as medication,
gastric pH, infection and tube care. We recommend that you have a
replacement feeding tube available in case of inadvertent tube
removal or failure. If the tube fails and you have been properly
trained, you may replace the tube. If you have not been properly
trained or your clinician prefers to replace the tube, you should
contact your clinician as soon as possible as the stoma may begin
to close within 2-4 hours.
Q: How do I prevent the feeding tube from becoming clogged?
Proper tube flushing is the best way to avoid clogging
the tube. Flush the tube with water every 4-6 hours during
continuous feeding, before and after every intermittent or bolus
feeding, or at least every 8 hours if the tube is not being
The feeding tube should also be flushed before and after
administration of medications and after checking for stomach
residuals. Medications should be given in liquid form. If a
medication is only available in tablets or capsules, make sure it
can be crushed and mixed with water. Medication should not be mixed
with formula. Never crush enteric-coated medication. Before and
after giving medication, the port should be flushed with water.
When flushing a tube, use water and a 30cc-60cc catheter tip
syringe. Do not use smaller sizes as this can increase pressure on
the tube and potentially rupture the tube. The amount of water used
to flush the tube will depend on the individual's needs, clinical
condition and type of tube, but the average volume ranges from
10-50 ml for adults, and 3-10 ml for children. Do not use excessive
force to flush the tube as this can perforate the tube and can
cause injury to the gastrointestinal tract.
Q: How should medications be given?
Medications should be given in liquid form. Thick medication can
plug the feeding port.
If a medication is only available in tablets or capsules, make
sure it can be crushed and mixed with water.
Medication should not be mixed with formula as they may harden
together and cause the tube to become occluded.
Never crush enteric-coated medication.
Before and between each medication the port or
tubing should be flushed with water.
Q: What do I do if there is gastric leakage from the stoma site?
If you suspect gastric leakage:
Leaks can also be caused by improper patient positioning, by
infusing the feeding formula too rapidly, or by feeding too large a
volume. Keep the head of the patient elevated at least 30 degrees
during, and 1 hour after feeding. This will also help to prevent
aspiration. If the feeding volume is too large, consult your
clinician as to whether you should change to smaller, more
frequent, or continuous volume feedings.
Q: How does the MIC* (Bolus) Gastrostomy Feeding Tube work?
The MIC* (Bolus) Gastrostomy Feeding Tube is used to
provide a means of accessing the stomach to provide nourishment,
liquids and medication. It may also be used as a means to release
excess air or contents from the stomach.
The MIC* (Bolus) Gastrostomy Feeding Tube is made of
silicone and is kept in place by an internal balloon that keeps the
tube from falling out of the stomach and a SECUR-LOK*
external retention ring or bolster that keeps the tube
from migrating into the stomach.
Q: What is the procedure for replacing the gastrostomy feeding tube?
The specialist will decide when to replace the gastrostomy
feeding tube. You may change the gastrostomy feeding tube yourself
provided you have been properly trained and have been given
permission to do so. Note: Do not try and replace a jejunal or
transgastric-jejunal tube yourself, this should only be done by
Steps for replacing your gastrostomy tube:
Q: What if the balloon will not deflate?
If water cannot be extracted from the balloon with the syringe,
make sure the recess in the balloon valve is clean and that the
valve is not blocked by food. Clean inside the recess, then firmly
seat the syringe into the valve, push and twist a quarter turn. Try
pulling back on the plunger again. If the balloon will not deflate,
use the end of a large paper clip to depress the valve and release
the water. Make sure to have a replacement tube to insert into the
Q: What if the feeding administration set becomes disconnected?
If the feeding administration set becomes disconnected from the
MIC-KEY* extension set tubing, stop the pump and estimate the
amount of formula lost. Thoroughly wipe the tube connections with
soap and water or alcohol. Clean inside the MIC-KEY* extension set
feeding port with a cotton-tipped applicator and alcohol. Irrigate
the tube with warm water. Dry the connections and firmly reconnect
the tubes with a quarter turn. Resume feeding.
Q: How should the end user/patient be positioned during feeding?
Correct feeding position is essential to avoid aspiration of
stomach contents through the esophagus and potentially into the
lungs. The end user/patient should be placed in an upright position
or at least at a 30-degree angle during, and one hour after
Q: How is the MIC-KEY* extension set attached?
To attach the right angle MIC-KEY* extension set, align the
black line on the set with the black line on the feeding port.
Insert the "nose" of the Secur-Lok* connector into the MIC-KEY*
feeding port, then rotate it a quarter turn clockwise. Next, open
the MIC-KEY* extension set feeding port and attach the feeding bag
connector to the extension set by firmly pushing and twisting. The
MIC-KEY* extension set will swivel with movement, which allows the
user to change position during feeding.
Q: What types of skin and stoma problems can occur?
Be on the alert for the following signs and symptoms of stoma
If any of these conditions occurs, contact your clinician for
advice on how to treat the problem.
