Re: [IPk] Length for infusion site
I found some extremely interesting points in the answers to my question. I
know many of the points obviously eg regarding inflammation and possible
soreness of site etc. and I'm not getting marks or lumps with my Humalog
even if I leave it in longer and the sites look OK although I have never
actually looked at the site with a magnifying glass - LOL.
In general I think I do mine about twice a week and wonder if mine is
rejected as John says. How do you recognise this rejection? You say in a
separate paragraph that as time wears on the insulin is often less
predictable and this is the point I was interested in finding out if
happened to any one as at the moment I have been thinking that perhaps this
is the reason for my poor control. Also John I'm afraid I also sometimes
forget to bolus - it is so easy to do this if your attention is caught up
with something else. I always remember before too long though. I wondered
if I had done this at lunch time today but was absolutely sure I had
bolused. I carefully checked and rechecked basals, also checked my maths
for the insulin:carb and a very long time later looked at the bolus I had
given. I am ashamed to say that I had given 0.8 instead of 8!! I had been
rather low when I bolused and was surprised at what I had done. But how
useful to be able to do this.
I was also interested to see that you, John, bolused 4 and injected 5. Why
didn't you do it all by one method?
Lastly, the depth of the infusion was interesting. I do not know if it is
possible to use a deeper infusion set with the Minimed 508.
