Does anyone know what might cause infusion sites to bleed beyond just a "bad site"? I have had ongoing problems with allergies to infusion sets over the past few years which. I am currently using Comforts (same as Minimed Silhouettes, I believe) and my endo recommended I try needle sets to see if that helps. I've been putting this off because the last time I tried needle sets they bled about 50% of the time I used them, for some reason. Still, I need to get my butt in gear and call the nurse my endo gave me.
Currently, I am changing my sets every two days, by which point they are usually fairly itchy, and I change them sooner if they get irritated or itchy before the two-day mark. I'm also taking extra-strength antihistamines daily for seasonal/environmental allergies and also Benadryl some days if I have an outright allergic reaction (usually to food). For the past month or two this seemed to work well so it just encouraged me to put off calling the diabetes nurse.
I usually mever have problems with sites bleeding except the needle sets above. The past few weeks, however, I've had three instances of my sites just completely dying and being covered in blood when I remove them. I don't think these are "bad sites" because they don't hurt going in and work fine for the first 24 hours. One was on my left abdomen, one on my right abdomen, and one on my right arm, so they haven't been in the same areas, either.
Basically what happens is I test, find my blood sugars in the 20-25 mmol/L range (350-450 mg/dl), don't come down for hours, and when I remove the site the adhesive is bloody (but not the cannula).
This happened today at work, I tested after lunch at 20.7 (373 mg/dl) and after three corrections was still 11.8 (212 mg/dl) almost six hours later without eating. When I changed my site, there was dried blood all over the adhesive, but nothing on the cannula, and it wasn't a "gusher" and didn't feel overly itchy or irritated. This site was in for 1.5 days and seemed fine until this afternoon.
Just wondering if anyone else has had this. Is it a continuation of my allergy problem? (In which case, I need to suck it up and give the needle sets another try.) I'm not anymore active than usual, don't think the sites are getting jostled or anything, and I am just confused.
The only other thing I can think of (and I thought of it just now while writing this post) is that I have had instances where the insulin "leaks" out of the site. Usually I notice this when I have an unexplained high and then smell insulin during a bolus and/or notice a wet spot near my site. I didn't notice that these past few times, but when it's happened in the past I've noticed blood on the adhesive. Again, I wonder if this could be caused by allergies (maybe swelling/inflammation of the skin) or something else?
I think it is really time for me to switch up my infusion set ...
