Dexcom one + wire broke off

[zaphod37]

I recieved a dexcom one sensor as part of a trial, I attatched it to the underside of my arm. The app threw up an error and told me to remove the sensor which I did. However when I looked at the sensor I notices the wire had broke off and wasnt on the table where i was sitting.

Has this happened to anyone else? I do have an appointment at urgent care in the morning just to see if the wire is still in my arm.

Take care all.

I've been using Dexcom One for a couple of years now and never had a problem with it. Personally I find it infinitely more reliable than Freestyle.

Thanks for the reply, I must have just been unlucky then. Urgent care examined the site but couldnt determin if anything was in there, as its plastic it wont show up on xray so they advised to keep an eye out in case of any infection. Chances are its on the floor somewhere but its so small and fine i cant see it. Dexcom are sending me a replacement and a return label to send the faulty one back.

Thanks for the info. Its the first time using this system so i probably over reacted, but the urgent care staff were great. Its reassuring to hear from others that have had this experience.

Hi,

If the probe is still under the skin?
Keep an eye out for any reaction as if a splinter or thorn is imbedded.

To be frank though,
I wonder (would also question.) if the actual probe was incorporated with the Dexcom assembly in the first place?
Hence the error…

 

[zaphod37]

There was deffinately a probe when I took off the cap of the applicator, but yeah I wonder if it was properly attatched. We couldnt feel anything under the skin but then its so fine, i guess it would be difficult to detect. I will certainly keep an eye out in case of infection tho. Thanks for the reply.

I’m not familiar with the D1.
But what’s normally seen easily when prepping to fit on inspection is the “hole punch” that retracts after doing it’s job burying the probe?
With the libre the hole punch is U shaped spike & contains the probe within the U.
From memory when I used the Dexcom 6 the principle was similar though I found the applicator a funny angle..

The insertion filament is not plastic - it would not conduct electricity if it was.

It may not show up on an X-ray though because it is so fine, OR as Jaylee points out, it was never there in the first place.

Ah ok, thanks now I see the point, as always you folks always help and i am very grateful for that.

I had problems with my Dexcom One+ triaI. I attached the sensor on my stomach just to the left of belly button and up a bit (carefully following instructions). My first reading came through as 2.3 and then settled into a succession of readings of 2 - so something obviously wrong. After about 15 hours it stopped sending readings and I got an error message telling me to remove sensor.

When I looked at the sensor there was no needle sticking out of the sensor like there always is with a libre. There was a bit of blood on the sensor and looking down the hole in the centre of the sensor there was a bit of bent wire that looked like the end of a paper clip. There was no mark on my skin.

I reported this in a detailed email to Dexcom and have had no response at all from them! I had told them that I was going to report my Dexcom One+ trial findings to my local Coventry Diabetes UK meeting so I am a bit surprised they didn’t get back with an offer of a replacement trial sensor.

Maybe I will buy a new sensor as I am specially interested in testing how effective calibration is.

I phoned them and got straight through, she offered to send me a new sensor and asked me to send the faulty one back.

I have found out how to restart the Dexcom ONE sensor (won't go into the details here - please check Youtube if interested )
Allow for leaving the transmitter out for 1 hour and then the 2 hour warm up. (3 hrs total).
You will (preferably) need the sensor's original code to re-activate it (but any valid code is OK) but when it fires up it usually reads about 4mmol higher than a blood test.
Recalibration does not always work first time and it doesn't seem to like large adjustments (like 4mmol) so I do it twice and it comes back into range relatively easily.
Have got as much as 17 days on a sensor - by which time it's usually not sticking very well.

I've been using Dexcom1/1+ for a few years now, but I've very recently had two sensors fail in similar way to what you describe. The filament was visible when I looked at the sensor before fitting, but after fitting there was something sticking out of the black dot on the top of the sensor. One of these sensors failed during warm up, and one came back with a failure within seconds after pairing. Removing the sensor showed no filament on the skin side of the sensor, or in my skin. I'm going to try phoning them in the next few days, so I'll report back.

Interesting post, I migrated from Libre to Dexcom One+, been using it for 180 days, and today this happened to me, the filament was definitely present before insertion, warm up completed and failure popped up stating remove !

On removal I did think is that still in my arm! There was a puncture mark!

I’m having second thoughts about Dexcom this is now the fourth failure, I’m going to pause my sub and think about it!

1. Failed after 6 days
2. Failed after 4 days
3. Failed in 24 hours
4. Failed in warm up

Apart from knocking a sensor off with Libre never had any failures I wonder when I request the next faulty replacement if Dexcom are going to say - no

And I pay privately for these!

I do like the additional patch with Dexcom and always on Bluetooth is good, but the app is somewhat poor! We’ll see!

I do wonder considering the private cost of money would be better spent on Healthy Diet Subscription too lose weight as I put my T2 into remission before just need to motivation and will power!

I paid privately for my dexcoms until New Zealand Pharmac finally started funding them for T1s last year. Yes, you do get occasional failures but they always replace them. 4 in 180 days sounds about right to me. (Disclaimer, that's using G7 ad not the One+ but the two products are very similar.)

Thanks, seems a high failure rate!

Log another ticket for replacement tomorrow it would seem

I'm going to try phoning them in the next few days, so I'll report back.

I contacted Dexcom by telephone about the missing filaments, and was sent 2 replacement sensors (3 total replacements in the last two months, in spite of their website saying they would only replace 2 per annum). I'm NHS funded in the UK, but my prescription is limited to 3 sensors every 30 days, so I'm often taking days off to make up for failures.

Out of my previous 9 sensors before the phone call, only one had lasted the full period. Two had failed during warm-up (see above),one lasted 9 days, two lasted 8 days, two lasted 7 days, and one lasted 6 days. So 32 days without sensors out of 90 days!

All my previous sensors were fitted around the waist, so I decided to try fitting to my arm. So far I have had two sensors last the full period when arm fitted.I'm skinny and spent most of my time seated.

If you apply for a replacement using the Dexcom on-line web form, they ask you lots of questions, in spite of being logged in to your personal account which has most of those details already. You'll also need to have 'Clarity' running, so you can tell them when the sensor was started, and when it failed. If they agree to a replacement and ask for a return of the failed one, you'll need to return both the spring loaded applicator and sensor, so don't bin the applicator until the sensor has run its full life.
