The biggest challenge I’ve had with my Abbott FreeStyle Navigator 2.0 CGM is keeping the sensor stuck to my skin. At first I didn’t use anything, relying on the default adhesive used by Abbott, but this didn’t work too well, as I was shedding sensors like a lizard sheds its skin. he combination of a hot/humid climate and lots of tennis was lethal for the on-board adhesive So I moved to after-market products and here’s what I’ve tried so far:
Then someone recommended that after attaching the sensor, I affix it some strips of Hyporplast , a 100% polyester, white adhesive used for medical devices.This looks very much like the default adhesive used by Medtronic in their Quick-set® infusion sets which very rarely detach. While Hyporplast works great when in-built on my infusion sets, it was not getting the job done as an add-on to my FreeStyle II CGM sensor. I had to replace the strips daily, the polyester material was not so comfortable on my skin, and it felt a little thick for me.
The next referral was for ConvaTek AllKare protective barrier wipes, a non-water soluble barrier film layer on the skin. After cleaning the insertion area with an alcohol swab and letting it dry, I rub the wipe on the skin, effectively creating a very sticky fly trap. Then I attach the sensor mount adhesive to the wiped area. This made things far better, but I still wasn’t always able to get the full five days out of my sensor before it was falling off. My search continued.
Next up was another adhesive, this time a spray: Hollister Medical Adhesive, a silicone spray that is not supposed to be affected by water. This adhesive is so strong that it is highly recommended for prosthetic devices! I found this spray to work as advertised. Unfortunately, even though I do not have particularly sensitive skin, my skin reacted unfavorably to the spray and I broke out in a nasty rash.
Last but certainly not least, a nurse at my endo’s office hooked me up with some clear film strips which turned out to be Smith & Nephew Opsite Flexifix. Flexifix is a transparent & waterproof acrylic adhesive that solved my problems. It is very thin – around 2.5mm – which is just a little more than a layer of skin!
After experimenting with various combinations, I have found the winning recipe for me: I begin by prepping the skin with ConvaTel AllKare; apply the sensor to the barrier wiped area; and then reinforce it with four strips of Flexifix.
Please let me know what works for you!
