Re: [IPk] Cathator Life

Is it the needle that lasts longer, or is it an individual thing? I wasn't
warned about skin reactions so I got a lot in the first couple of weeks,
trying to make a silhouette set last 6 days! I soon learned my lesson.

One thing I noticed though, all the reactions were red, painful, tender and
firm to touch, and in anyone else I would have assumed they were abscesses
at once and started antibiotics. But I never did, and all of these settled
down, with gradual disappearance of the lump after around 2 weeks.

Because of this, I think they are NOT infections but just tissue reactions
to the catheter. A colleague who specialises in pumps thinks the same
because the reaction occurs even if no insulin is being pumped through the
cannula. This has some implications, firstly that antibiotics may not be
needed as often as they are prescribed for this, and secondly the question
remains, what is the long-term consequence of all this tissue reaction? I'm
very lucky to have used animal insulin without skin reactions, and nearly 3
decades of injections with no long-term skin consequences. I don't want them
to start now.

Does anyone have similar experience, and is there anyone with many years of
pumping behind them who can enlighten me about the long-term effects on the
