Replacing The Mic-Key* Sf Feeding Tube; Duration Of Use; Mri Safety Information; Problem Solving - Halyard MIC-KEY SF Anweisungen

REPLACING THE MIC-KEY* SF FEEDING TUBE

DURATION OF USE

The life span of the tube varies according to several factors. These factors may include medications,
volume of sterile or distilled water used to inflate the balloon, gastric pH and tube care.
The MIC-KEY* SF G-Tube is designed to function properly for 3 months of normal use. The
MIC-KEY* SF Extension sets with ENFit
®
normal use.

MRI SAFETY INFORMATION

Non-clinical testing demonstrated that the MIC-KEY* SF Low-Profile Gastrostomy Tube is MR
Conditional. A patient with this device can be safely scanned in an MR system meeting the following
conditions:
• Static magnetic field of 3-Tesla or less
• Maximum spatial field gradient magnetic field of 720-Gauss/cm or less
In non-clinical testing, the MIC-KEY* SF Low-Profile Gastrostomy Tube produced the following
temperature rise during MRI performed for 15-min of scanning (i.e., per pulse sequence) in the
3-Tesla (3-Tesla/128-MHz, Excite, HDx, Software 14X.M5, General Electric Healthcare, Milwaukee, WI)
MR system:
• Highest temperature change +1.8˚C
Therefore, the MRI-related heating experiments for the MIC-KEY* SF Low-Profile Gastrostomy Tube
at 3-Tesla using a transmit/receive RF body coil at an MR system reported whole body averaged
SAR of 2.9 -W/kg (i.e., associated with a calorimetry measured whole body averaged value of 2.7-W/
kg) indicated that the greatest amount of heating that occurred in association with these specific
conditions was equal to or less than +1.8˚C.
In non-clinical testing, it has been shown that MR image quality may be compromised if the area of
interest is in the exact same area or relatively close to the position of the MIC-KEY* SF Low-Profile
Gastrostomy Tube. Therefore, optimization of MR imaging parameters to compensate for the
presence of this device may be necessary. The maximum artifact size (i.e., as seen on the gradient
echo pulse sequence) extends approximately 20-mm relative to the size and shape of the MIC-KEY*
SF Low-Profile Gastrostomy Tube.

PROBLEM SOLVING

WHEN TO CALL YOUR MEDICAL PROFESSIONAL:

1. If the stoma bleeds (more than a small amount), or if it looks like blood is mixed with
stomach contents, call your Medical Professional immediately.
2. The stoma is persistently red and sore.
3. The red area is larger than 2.5 cm in diameter.
4. The stoma emits an odor.
5. The skin surrounding the stoma is swollen.
6. There is pus around the stoma.
7. The patient has a fever.

STOMACH CONTENTS LEAK OUT AROUND THE TUBE

1. Check stomach residual (See "Residual" on page 11 for instructions). The stomach may be too
full or contain gas. If the stomach contains too much residual more than a few times, the patient
may be getting too much formula at one time.
• If you are using an intermittent or Bolus feeding, consider switching to continuous
feeding.
• If you are using a continuous feeding, try decreasing the flow rate.
2. Ensure that the balloon inside the stomach is filled by gently pulling on the tube and checking
for resistance. Check the Feeding Tube Information Section (page 3 and Table on Page 7) for the
prescribed balloon fill volume. Test the balloon by attaching a Luer slip syringe to the Balloon
Inflation Port. Withdraw the water from the balloon and note the volume in the syringe.
• If the amount is less than prescribed, refill the balloon with the prescribed amount of
sterile or distilled water, wait 10 to 20 minutes and repeat the procedure.
• If the prescribed volume of water is still in the balloon, try increasing the volume by 1 ml
at a time until the leak stops.
Important: Fill according to Balloon Fill Volume chart on page 7.
Caution: Use care while filling or removing water from the balloon. The MIC-KEY* SF Feeding
GRE
Tube may be easily pulled out.

as improper MIC-KEY* SF Feeding Tube sizing and improper feeding.
