Continuing the discussion from Medtronic 640g - Offical Details and photos:
I have tried inserting an Enlite on the back(ish) part of my upper arm three times so far. My experience with this is that it is sort of really good while also, at times, really annoying.
Good because I feel I get noticeably better performance from the sensor. ISIGs in my experience have so far been generally stronger and remained that way for a longer period over the life of the sensor. Also, the accuracy seems generally better as well. I also believe that … with the exception noted later … I tend to jostle the sensor less in that location as I go about my day to day activities. Another definite personal plus is that when my cats sleep on or walk over my stomach while I’m laying down, they won’t disturb the sensor.
FWIW, should anyone be curious, it’s a location where you can easily show someone what the sensor looks like without pushing up against common social TMI boundaries.
The really annoying aspect for me was essentially that there is an adjustment period to acclimate to the new sensor location. I definitely have to make sure the pump is always on the same side of my body as the sensor to avoid “Weak Signal” disconnects and alarms. I also found I have to consciously remember to not rip the sensor out when I’m washing my upper arm in the shower. (I tend to be on autopilot while I’m soaping and rinsing. )
Of course, the most obvious potential problem is the insertion and overtaping, especially if you are doing this by yourself. The trick of pushing the back of your upper arm “towards” you with the back of a chair is what I use. But applying a length of very sticky tape is consistently challenging to do while using only one hand. Getting the tape to lay smoothly so you don’t irritate your skin and also putting it exactly where you want it to go is definitely easier with two hands than one.
I have made one modification to Medtronic’s suggested order of insertion steps as an adaptation to working one handed. After inserting and very carefully removing the “serter”, I leave the insertion needle in place while I slowly & gently remove the white paper cover to affix the curved adhesive pad on an Enlite’s back end. It’s only after I have applied the rear adhesive pad that I move on to working on removing the insertion needle tower.
I do it this way because I think it may make it a little harder to accidentally pull out the sensor while I am tugging one-handed on that rear adhesive cover. Maybe it makes no difference, but, if nothing else, it makes me happier doing it this way. Probably not worth thinking about if you have someone other than a cat who can help you with that step.
One final question and slight digression. I would like to ask @swisschocolate and/or @Buckley83 and/or @ anyone else using Enlites outside the U.S., if you have ever spoken about inserting the Enlite in the upper arm with anyone from Medtronic or whomever you work with about CGM/Enlites in your doctor’s office. If so, what did they say?
I’m just looking for some anecdotal confirmation from personal experience on whether or not Medtronic presents a different policy towards CGM insertion sites outside of the U.S. versus inside.
