Hi All! 'Been pumping since last November with Animas Ping. I use both the Inset30 (angled) and Inset (straight-in.) Those have Teflon flexible cannulas (not steel needle.) I use the shortest available cannula length.
I run Apidra in the pump, and my basal rates could be considered low: about 14 U/day total and max rate is .75 U/hr throughout the morning.
I noticed my BG starts running high when I'm in my 3rd day on a set, and I'm guessing that's because the basal is not absorbing properly anymore. When I bolus for food or to correct it still works just as I expected.
When I change the set, I get good BG performance again.
I get the same pattern regardless if I have been very active exercising or just being a "slacker" so I have ruled out low activity as a cause.
Site exhibits red tenderness and slight swelling at cannula "dive" too, in the days following insertion.
On a couple of the straight-in sets, I had a lot of accumulated blood under the skin at the site (like a hematoma or blood blister) that bled profusely when I pulled the set out.
When I described all this to my witch blood doctor, he suggested I could try an anti-histamine to suppress my body’s reaction to the inset. I haven’t taken him up on that suggestion yet ....
OK so here's the Q's: does anyone else have similar experience (BG control is better when you change site every 2 days)? And does anyone have any tips or secrets for making the site last longer? I'd love to be able to stretch it out to 3 or 4 days for convenience...
