Jejunal Feeding Tube
The Kimberly-Clark* MIC* Jejunal Feeding Tube is indicated for
patients requiring jejunal feeding only. The distal tip can be
trimmed to suit individual patient needs.
Q: How does the MIC-KEY* feeding port work?
Nourishment and liquids are delivered through the tube and into
the stomach or jejunum through the feeding and medication
port. When not in use, the port should be capped off with the
attached cover. An anti-reflux valve located inside and toward the
top of the feeding port helps prevent stomach or
jejunal contents from leaking out of the tube. The valve is
opened with the extension set.
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: How is the MIC-KEY* tube placement verified?
Before feeding, check the MIC-KEY* tube to be sure it is not
clogged or displaced outside the stomach. You may do this by
drawing 5-10 ml of air into a syringe. Place a stethoscope on the
left side of the abdomen just above the waist. Inject the air into
the MIC-KEY* extension set feeding port and listen for the stomach
to "growl." Try again if you do not hear the sound. If you still do
not hear it, do not proceed to feed. Contact your specialist and
report the problem.
Another method is to connect the extension set to the feeding
tube and attach a catheter tip syringe with 10 ml of water to the
extension set feeding port. Pull back on the plunger. When stomach
contents appear in the tube, flush the tube with water.
Check for leaking around the stoma. If at any time you suspect
the feeding tube has become dislodged, discontinue feeding and
contact your specialist to report the problem.
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: How should the feeding port and anti-reflux valve be maintained?
The port and valve should be kept very clean. To prevent dried
formula from lodging inside the recess and possibly holding the
valve open, flush thoroughly with water and complete the cleaning
with cotton-tipped applicators and water. Residual formula should
not be left to pool and dry inside the valve opening.
Caution: Do not push cotton-tipped applicators or other foreign
objects through the feeding port valve as this may cause the valve
to tear and leak.
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: How should the MIC-KEY* extension set be maintained?
The MIC-KEY* extension set should be washed after every feeding
with warm, soapy water, then rinsed thoroughly and allowed to air
dry. Prompt flushing and rinsing prevent the formula from drying
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.
