Bleeding while inserting Guardian sensor 670G

(Kathy) #1

My daughter was previously using the Dexcom and rarely had bleeding issues during sensor insertion. Now with the 670G Guardian sensor, it bleeds more than half of the times we attempt insertions. For the sensors that we haven’t been able to use, Medtronic has been great about replacing them. But it’s frustrating to put in multiple sensors every time, and it’s a hassle to call Medtronic every week to get replacements. We’ve had the bleeding issue with abdomen and arms. Have others had the same issue? Any suggestions to try and prevent this from happening? We have even had our Medtronic trainer come out and help/watch us do it, and she said that we were doing everything right.

Is the bleeding causing inaccurate readings? Mine bleed every few times but the readings are still accurate.

Usually it’s enough blood that we take it out and put in a new sensor. This past time it didn’t look as bad, so we just kept it in. So far it seems pretty accurate.

Try not pressing down on the inserter. Just holding it gently on the skin. Pressing too hard will cause bleeding.

I’ll suggest that to my daughter. Thanks!

I do not know if this will work for your 670G sensor, but I use a 630G sensor and I have had bleeding several times. This is what I do. I first put on an IV3000, then put the sensor on over and thru the IV3000. Since doing that I have not had a bleeding issue. Bleeding however, is not the reason I starting putting the IV3000 on first. I was sensitive to the adhesive strips Medtronic sends with the 630G sensors. The IV3000 has solved both problems for me, at lease so far.

That’s interesting. Thanks for the suggestion. I’m assuming that doing that way hasn’t negatively affected the sensor accuracy?

No. It hasn’t. In fact I believe it is more accurate. Maybe that is because there hasn’t been any bleeding. Keep working with it you will find what work best for you.

I have this is issue often. Like you said, I call Medtronic and get replacements too. Only if the blood bleeds through the backing will I replace it, otherwise a little blood in the sensor tip doesn’t seem to harm the accuracy of the sensor readings. It is super frustrating, I feel you. I once hit an vein and it bruised badly on my stomach (close to my belly button). I have since been trying the far sides of my abdomen and it bleeds much less.

I appreciate the suggestion. If we keep having issues, then I’ll try that. Thanks so much!

I wasn’t sure if this was common or not, so I feel a little better that we’re not the only ones (but I’m sorry that you’ve had similar issues). I definitely agree that farther out we have less issues. The closer to the belly button the more bleeding–I think especially since she has her pump sites there. Thanks for responding!

This is my experience as well. As soon as I lightened up on the inserter, bleeding stopped.

(Kathy) #13

Thanks for you input! I think that helped this last time.

My personal assistant has another T1D client, also using the 670G system, and we’ve been sharing information among the three of us. The other client apparently had bleeding problems until she started icing the area before sensor insertion. I remembered this thread, and was lucky enough to find it again. If you try this, please let us all know if it helps.
