Replacing The Mic-Key* Sf Feeding Tube; Duration Of Use; Mri Safety Information - Halyard MIC-KEY Séries Guide D'utilisation

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.
